1. 原文摘要
Despite the clinical success of programmed cell death protein 1 (PD-1) checkpoint blockade in many cancer types, its efficacy in glioblastoma remains notably limited, underscoring the critical need to uncover primary resistance mechanisms and identify synergistic therapeutic targets. To discover genes modulating αPD-1 immunotherapy response, we performed an in vivo CRISPR-Cas9 screen in immunocompetent mice bearing glioblastoma, which prioritized the glutamine (Gln) transporter SLC38A5 as a candidate modulator of αPD-1 immunotherapy efficacy. In human glioblastoma, SLC38A5 was significantly upregulated compared with normal brain tissue. Ablation of SLC38A5 did not impair glioblastoma cell intrinsic growth but profoundly sensitized glioblastoma to αPD-1 therapy in a CD8+ T cell-dependent manner, leading to enhanced anti-tumor immunity and tumor control. Mechanistically, SLC38A5 deficiency created a Gln-enriched tumor microenvironment by impairing Gln uptake of glioblastoma cells. This metabolic rewiring enhanced CD8+ T cell function via SLC1A5-dependent Gln utilization and promoted MHC-I-mediated antigen presentation in glioblastoma cells through a Gln-glutathione (GSH)-reactive oxygen species (ROS) axis. Furthermore, an SLC38A5-targeting nanobody was developed that efficiently accumulated in orthotopic glioblastoma and potentiated αPD-1 therapy to suppress brain tumor growth in vivo. Overall, this study establishes SLC38A5 as a metabolic immune regulator in glioblastoma and presents a promising Nb-based strategy for overcoming αPD-1 immunotherapy resistance.

尽管PD-1检查点阻断在多种癌症中取得临床成功,但其在胶质母细胞瘤中的疗效明显有限,因此亟需揭示原发性耐药机制并发现协同治疗靶点。本研究在携带胶质母细胞瘤的免疫正常小鼠中进行体内CRISPR-Cas9筛选,发现谷氨酰胺转运体SLC38A5是调控αPD-1免疫治疗反应的关键候选基因。人胶质母细胞瘤中SLC38A5较正常脑组织显著上调。敲除SLC38A5不影响肿瘤细胞内在生长,但能以CD8+ T细胞依赖的方式显著增敏αPD-1治疗。机制上,SLC38A5缺失削弱肿瘤细胞谷氨酰胺摄取,营造谷氨酰胺富集的肿瘤微环境,通过SLC1A5增强CD8+ T细胞功能,并通过谷氨酰胺-谷胱甘肽-活性氧轴促进肿瘤细胞MHC-I介导的抗原呈递。研究还开发了靶向SLC38A5的纳米抗体,可在原位胶质母细胞瘤中有效蓄积并增强αPD-1疗效。该研究确立了SLC38A5作为胶质母细胞瘤代谢免疫调控因子的地位,并提出了一种有前景的纳米抗体策略用于克服免疫治疗耐药。

1. 原文摘要
Circulating tumor cells (CTCs) carry multidimensional information from primary tumors, yet current separation strategies lead to insufficient quantity of cells available for robust downstream analyses. To address this issue, we propose an in-vivo capture strategy for high-quantity CTC enrichment based on a multinanobody-functionalized carboxymethyl cellulose cryogel (MNB-PAACcryo). By addressing the trade-off between pore size and mechanical property, the MNB-PAACcryo sets up a sieving barrier in the bloodstream. It allows free passage of blood cells through its interconnected macropores, while enhancing CTC-nanobody interactions, contributing to a high CTC capture efficiency of 72.3 ± 4.5% in the bloodstream. Consequently, up to 2.7 × 103 CTCs could be harvested from 4000 mL blood at 1 CTC/mL using 0.1 cm3 of the MNB-PAACcryo. In vivo experiments on cancer rat models demonstrated that the MNB-PAACcryo could capture diverse CTC subtypes across multiple cancers, and the captured CTCs exhibited consistent information with the primary tumor tissues. With its robust capability for high-quantity CTC enrichment, the proposed strategy will not only improve the reliability of CTC-based cancer analysis, but may also facilitate the establishment of patient-derived tumor organoid, showing great potential to accelerate the development of personalized cancer medicine.

循环肿瘤细胞(CTC)携带原发肿瘤的多维信息,但现有分离策略获得的细胞数量不足,影响下游可靠分析。本研究提出一种基于多纳米抗体功能化羧甲基纤维素冷冻凝胶(MNB-PAACcryo)的体内高量CTC富集策略。通过平衡孔径与力学性能,MNB-PAACcryo在血流中形成筛分屏障:互连大孔允许血细胞自由通过,同时增强CTC-纳米抗体相互作用,使血液中CTC捕获效率达72.3 ± 4.5%。使用0.1 cm³的MNB-PAACcryo可从4000 mL血液(1 CTC/mL)中富集约2.7 × 10³个CTC。癌症大鼠模型实验显示,该材料可捕获多种癌症的异质性CTC亚群,且捕获细胞与原发肿瘤组织信息一致。该策略不仅能提高基于CTC的癌症分析可靠性,还可能促进患者来源肿瘤类器官建立,推动个体化癌症医学发展。

1. 原文摘要
Radiotherapy (RT) remains a cornerstone in lung cancer treatment, but its efficacy is often limited by radioresistance and an immunosuppressive tumor microenvironment (TME). Here, we identify the deubiquitinating enzyme USP8 as a key regulator of M2-like tumor-associated macrophages (TAMs) in the irradiated TME. To exploit this finding, we developed a biomimetic nanoparticle, USP8@CPMOF, which co-delivers a USP8 inhibitor and an anti-PD-L1 nanobody-coated membrane. This nanosystem specifically targets both irradiated tumor cells and TAMs, responding to the acidic and high-glutathione TME to trigger ferroptosis and release the USP8 inhibitor. In vitro, USP8@CPMOF enhanced RT-induced apoptosis and ferroptosis, promoted dendritic cell maturation, and reprogrammed M2 macrophages toward an M1 phenotype. In vivo, it improved tumor accumulation, synergized with RT to suppress tumor growth and metastasis, and robustly remodeled the TME by increasing cytotoxic T cell infiltration and reducing immunosuppressive cells. This work presents a promising nanomedicine strategy to overcome radioresistance by simultaneously targeting tumor cells and the immunosuppressive TME.

放疗是肺癌治疗的基石,但其疗效常受放射抗拒和免疫抑制性肿瘤微环境(TME)限制。本研究发现去泛素化酶USP8是放疗后TME中M2样肿瘤相关巨噬细胞(TAM)的关键调控因子。基于此,研究者开发了仿生纳米颗粒USP8@CPMOF,共递送USP8抑制剂和抗PD-L1纳米抗体包被膜。该纳米系统可特异性靶向受照射肿瘤细胞和TAM,响应酸性、高谷胱甘肽的TME触发铁死亡并释放USP8抑制剂。体外实验中,USP8@CPMOF增强放疗诱导的凋亡和铁死亡,促进树突状细胞成熟,并将M2型巨噬细胞重编程为M1型。体内实验显示其改善肿瘤蓄积,协同放疗抑制肿瘤生长和转移,并通过增加细胞毒性T细胞浸润、减少免疫抑制细胞来重塑TME。该工作提出了一种同时靶向肿瘤细胞和免疫抑制性TME以克服放射抗拒的纳米医学策略。

1. 原文摘要
Rheumatoid factor (RF), an autoantibody targeting IgG, is a key diagnostic marker of autoimmune diseases, especially rheumatoid arthritis (RA). In patients with RA, high RF titers have been reported to be associated with disease severity and may influence the pharmacological behavior and clinical response of certain biologic agents, including tumor necrosis factor (TNF) inhibitors. TNF inhibitors are widely used biologic agents in RA treatment and include two structure types: the fragment crystallizable (Fc)-containing protein (e.g. IgG) and the Fc-free protein. Clinical studies have suggested that in RA patients with high RF titers, sufficient circulating drug concentrations are more likely to be maintained with Fc-free TNF inhibitors than with Fc-containing TNF inhibitors. To clarify the mechanisms underlying this clinical observation, we investigated whether RF differentially alters FcRn-dependent recycling and macrophage uptake of the Fc-containing antibody adalimumab and the Fc-free, human serum albumin (HSA)-binding NANOBODY® compound ozoralizumab (OZR) using an ELISA-based RF-binding assay, an FcRn-mediated recycling assay in FcRn-expressing cells, and a mouse macrophage phagocytosis assay. In a RF binding assay, OZR showed minimal binding to RF. In the FcRn-mediated recycling assay, the recycling efficiency of OZR was not affected by high RF titers. In contrast, adalimumab, an IgG type of TNF inhibitor, exhibited clear interaction with RF and its recycling efficiency decreased in the presence of high RF titers. Furthermore, in a mouse macrophage phagocytosis assay, immune complexes containing the Fc-containing adalimumab, but not the Fc-free OZR, showed increased macrophage uptake in the presence of RF. In summary, our findings demonstrate that the HSA-binding property of OZR enables preservation of HSA-mediated FcRn recycling and avoids RF-enhanced immune-complex phagocytosis under high-RF conditions. These mechanisms may contribute to the maintenance of stable circulating concentrations and therapeutic efficacy of OZR in RA patients with high RF titers.

类风湿因子(RF)是靶向IgG的自身抗体,为自身免疫病(尤其是类风湿关节炎,RA)的关键诊断标志物。RA患者中高RF滴度与疾病严重度相关,并可能影响某些生物制剂(包括TNF抑制剂)的药代动力学和临床反应。TNF抑制剂包括含Fc蛋白(如IgG)和不含Fc蛋白两类。临床研究表明,在高RF滴度RA患者中,不含Fc的TNF抑制剂比含Fc者更易维持有效循环药物浓度。为阐明机制,本研究通过ELISA RF结合实验、FcRn表达细胞再循环实验及小鼠巨噬细胞吞噬实验,比较RF对含Fc抗体阿达木单抗与不含Fc、结合人血清白蛋白(HSA)的纳米抗体药物Ozoralizumab(OZR)的影响。结果显示,OZR与RF结合极少;FcRn介导的再循环效率不受高RF滴度影响。相反,IgG型阿达木单抗与RF有明显相互作用,高RF滴度下再循环效率降低。小鼠巨噬细胞吞噬实验中,含Fc的阿达木单抗免疫复合物在RF存在下吞噬增加,而OZR无此现象。OZR的HSA结合特性使其在高RF条件下保留HSA介导的FcRn再循环,并避免RF增强的免疫复合物吞噬,这可能解释其临床药代动力学优势。

1. 原文摘要
Inflammatory bowel disease (IBD) patients disproportionately suffer from depression and anxiety, which exacerbate clinical outcomes yet remain inadequately addressed by current anti-tumor necrosis factor (TNF) biologics. To bridge this therapeutic gap, we engineered Escherichia coli Nissle 1917 (eEcN) as a clinically translatable living microbial therapeutics platform for dual-targeted intervention. eEcN is designed to autonomously secrete immunomodulatory outer membrane vesicles (OMVs) bearing TNFα-neutralizing nanobodies (TNFαnb). These bioengineered nanovesicles specifically target inflamed colon tissue, enabling localized TNFα blockade, mucosal healing, and immune regulation. Concurrently, the eEcN remodels the gut microbiota, increasing symbiotic Lactobacillus abundance to elevate intestinal γ-aminobutyric acid (GABA) levels, addressing a core neurotransmitter deficit in IBD-associated depression. In murine colitis models, this integrated strategy surpassed conventional anti-TNF therapy, simultaneously ameliorating intestinal pathology and depression-like behaviors. Mechanistically, eEcN attenuated neuroinflammation and restored hippocampal GABAergic neurotransmission via the gut-brain axis. This engineered living biomaterial platform, synergizing targeted OMVs-mediated nanobody delivery with microbiota-driven neurometabolite production, represents a promising approach for the complex pathophysiology of IBD and its neuropsychiatric comorbidities.

炎症性肠病(IBD)患者常伴发抑郁和焦虑,加重临床结局,但现有抗TNF生物制剂对此改善有限。本研究将大肠杆菌Nissle 1917(eEcN)工程化为可临床转化的活体微生物治疗平台,实现双重靶向干预。eEcN可自主分泌携带抗TNFα纳米抗体(TNFαnb)的免疫调节性外膜囊泡(OMV)。这些生物工程化纳米囊泡特异性靶向发炎结肠组织,实现局部TNFα阻断、黏膜愈合和免疫调节。同时,eEcN重塑肠道菌群,增加共生乳杆菌丰度,提升肠道γ-氨基丁酸(GABA)水平,改善IBD相关抑郁的核心神经递质缺陷。在小鼠结肠炎模型中,该整合策略优于传统抗TNF治疗,同时改善肠道病理和抑郁样行为。机制上,eEcN通过肠-脑轴减轻神经炎症并恢复海马GABA能神经传递。该工程化活体生物材料平台将靶向OMV介导的纳米抗体递送与菌群驱动的神经代谢产物生成相结合,为IBD及其神经精神共病的复杂病理生理提供了有前景的治疗策略。

1. 原文摘要
Finding therapeutic antibodies that bind multiple related targets with high affinity and favorable biophysical properties remains challenging and resource-intensive. For snakebite antivenoms, this challenge is critical as treatments must neutralize toxins across multiple snake species. We developed a pipeline combining high-throughput yeast screening, deep sequencing, and AlphaFold3 structure prediction to identify polyspecific variable domains of heavy chain-only antibodies (VHHs) against long-chain α-neurotoxins. Multiplexed yeast display screening generated a dataset of diverse hits with varying binding specificities. AlphaFold3-generated VHH-toxin complex predictions enabled stringent high-precision structural triage of polyspecific VHHs that bind conserved epitopes across multiple toxins, with a representative subset experimentally confirmed to block toxin binding to the acetylcholine receptor. These structural insights provided a starting point for computational optimization of affinity and soluble expression of the VHHs, with experimental validation confirming that optimized VHH variants maintained broad binding specificity across toxins. This integrated approach supports structure-guided prioritization of polyspecific VHH hits, offering a high-precision filter that could reduce future reliance on extensive experimental specificity screening and providing a framework applicable to other therapeutic contexts, in which substantial antigen variation occurs and broad neutralization is essential.

1. 原文摘要
Nod-like receptor family pyrin domain-containing 3 (NLRP3) is activated by many stimuli, and its dysfunction is involved in various inflammatory diseases. Activation of NLRP3 is thought to happen via a multistep process involving phase separation, conformational opening and oligomerization. However, how NLRP3 is released from its autorepressed conformation remains elusive. Here we report that activating molecule in Beclin1-regulated autophagy protein 1 (AMBRA1), previously known for its role in autophagy, bound NLRP3 to scaffold and allosterically activate NLRP3. AMBRA1 engaged the leucine-rich repeat and helical domain 2 subdomains of NLRP3 through its β-propeller domain and destabilized the closed, inactive conformation of NLRP3, facilitating adenosine triphosphate binding and transition of NLRP3 to the active state. AMBRA1 deficiency in monocytes or macrophages impaired NLRP3 activation and reduced inflammatory responses in mouse models of endotoxic shock, colitis and sepsis. Nanobodies blocking the interaction between AMBRA1 and NLRP3 inhibited NLRP3 activation, underscoring the therapeutic potential of targeting this interaction. Our study revealed the role of AMBRA1 in NLRP3 inflammasome assembly and activation, offering potential pharmacological targets for related diseases.

NLR家族pyrin结构域蛋白3(NLRP3)可被多种刺激激活,其功能失调与多种炎症疾病相关。NLRP3激活被认为涉及相分离、构象开放和寡聚化等多步骤过程,但其如何从自抑制构象中释放仍不清楚。本研究发现,Beclin1调控自噬蛋白1中的激活分子(AMBRA1)通过与NLRP3结合并变构激活NLRP3发挥作用。AMBRA1通过其β-螺旋桨结构域与NLRP3的亮氨酸富集重复序列和螺旋结构域2亚区结合,破坏NLRP3闭合无活性构象,促进ATP结合并向活性状态转变。单核细胞或巨噬细胞中AMBRA1缺失会损害NLRP3激活,并减轻内毒素休克、结肠炎和脓毒症小鼠模型中的炎症反应。阻断AMBRA1-NLP3相互作用的纳米抗体可抑制NLRP3激活,凸显了靶向该相互作用的治疗潜力。该研究揭示了AMBRA1在NLRP3炎症小体组装和激活中的作用,为相关疾病提供了潜在药理学靶点。

1. 原文摘要
Chemotherapy can substantially enhance the efficacy of cancer immunotherapy; however, the clinical translation of chemoimmunotherapy is frequently hampered by inefficient drug delivery and dose-limiting systemic toxicity. To address these challenges, we engineered a tumor-targeting Salmonella typhimurium-based platform (VNP@PD-L1nb/DOX) that simultaneously enables localized chemotherapy and in situ PD-L1 blockade. The attenuated Salmonella typhimurium strain VNP20009 was genetically engineered to secrete PD-L1-targeting nanobodies (PD-L1nb), and surface-functionalized with a phenylboronic acid (PBA)-conjugated doxorubicin prodrug (DOX-PBA) via reversible boronate ester bonds. This design allows hydrogen peroxide (H2O2)-responsive release of active doxorubicin within the tumor microenvironment while maintaining negligible toxicity toward normal tissues and the bacterial carrier itself. The engineered bacteria exhibited pronounced tumor-selective accumulation and continuously secrete PD-L1nb into the extracellular space for PD-L1 selective blockade. In a murine triple-negative breast cancer (TNBC) model, VNP@PD-L1nb/DOX significantly suppressed tumor growth, induced immunogenic cell death (ICD), and promoted robust systemic immune activation. The ICD-driven immune priming, together with localized PD-L1 blockade, synergistically enhanced intratumoral infiltration and activation of CD8+ T cells while concurrently depleting regulatory T (Treg) cells. Collectively, our findings underscore the promise of engineered bacterial vectors as a versatile integrated platform for targeted chemoimmunotherapy in advanced solid tumors.

1. 原文摘要
Intratumoral injection is a well-established strategy for local cancer immunotherapy. However, its efficacy is critically limited by the spatially heterogeneous tumor microenvironment (TME), particularly the presence of hypoxic-necrotic regions that induce immunosuppression. The lack of reliable image guidance for precise intratumoral injection site selection remains a major challenge. Here, we developed an ultrasound-guided intratumoral delivery method based on aptamer-modified acoustic bacteria (AAB). AAB were genetically engineered to express gas vesicles (GVs) for enhanced ultrasound contrast and surface-modified with AS1411 aptamer via amide condensation to promote tumor accumulation. Following intravenous administration, AAB preferentially accumulate to hypoxic-necrotic tumor niches, enabling contrast-enhanced ultrasound (CEUS) imaging of these immunosuppressive niches. Guided by AAB-based CEUS imaging, therapeutic bacteria (TB), which were engineered to express a bacteriolytic protein and release CD47 nanobodies, were accurately injected either inside or outside the hypoxic-necrotic regions. Injection outside these regions yielded significantly superior antitumor efficacy. This enhanced therapeutic effect was mediated by preserved availability of functional CD47 targets on viable tumor cells, coupled with robust induction of M1 macrophage polarization and a potent pro-inflammatory immune microenvironment within the tumor. This study provides a practical image-guided strategy to overcome the therapeutic barriers imposed by intratumoral heterogeneity and maximize the efficacy of bacterial cancer immunotherapy.

瘤内注射是局部癌症免疫治疗的成熟策略,但其疗效受肿瘤微环境(TME)空间异质性限制,尤其是诱导免疫抑制的缺氧-坏死区域。缺乏可靠的影像引导以精确选择瘤内注射部位是主要挑战。本研究开发了基于适配体修饰声学细菌(AAB)的超声引导瘤内递送方法。AAB经基因工程表达气体囊泡(GV)以增强超声对比,并通过酰胺缩合修饰AS1411适配体以促进肿瘤蓄积。静脉给药后,AAB优先蓄积于缺氧-坏死肿瘤区域,实现这些免疫抑制区域的超声造影成像。基于AAB造影图像引导,研究者将工程化表达细菌裂解蛋白并释放CD47纳米抗体的治疗细菌(TB)精确注射至缺氧-坏死区域内或外。注射于区域外可显著增强抗肿瘤疗效,其机制在于保留活肿瘤细胞上的功能性CD47靶点,同时强力诱导M1巨噬细胞极化和肿瘤内促炎免疫微环境。该研究为克服瘤内异质性带来的治疗障碍、最大化细菌癌症免疫治疗疗效提供了实用的影像引导策略。

1. 原文摘要
Conventional CD3-targeting bispecific T cell engagers (BiTEs) have shown limited efficacy in solid tumors, largely due to the highly immunosuppressive tumor microenvironment (TME) and systemic T cell activation-associated toxicity. To address this challenge, we developed a peptide-MHC class I-based T cell engager platform that selectively redirects a specific subset of CD8+ T cells to tumor cells. Using the model ovalbumin (OVA) system, we engineered fusion proteins comprising an OVA peptide-H-2Kᵇ complex linked to an anti-HER2 nanobody (OVA-αHER2), enabling simultaneous engagement of OVA-specific T cells and HER2-expressing tumor cells and inducing potent tumor cell killing in vitro. To overcome the immunosuppressive TME, we further combined a HER2-targeted IL-12 fusion protein with OVA-αHER2, achieving synergistic anti-tumor responses in a mouse B16-HER2 solid tumor model. This treatment enhanced both systemic and intratumoral OVA-specific CD8+ T cell responses, accompanied by increased IFN-γ production in the TME. Together, these findings establish a modular immunotherapy strategy that integrates recruitment of a specific CD8+ T cell subset with localized cytokine-mediated immune reprogramming, providing a potential approach for HER2-positive solid tumors.

PURPOSE: This phase I clinical trial aims to evaluate the safety, expansion kinetics, and preliminary efficacy of nonarmored, nanobody-derived guanylyl cyclase 2C (GCC)-targeted chimeric antigen receptor (CAR) T cells in patients with heavily pretreated metastatic colorectal cancer. PATIENTS AND METHODS: In this single-arm, open-label, phase I clinical trial, 24 patients who received at least 2 prior lines of treatment received GCC-targeted CAR T cells across 4 dose levels: 0.5 × 105, 1 × 106, 2 × 106, and 3 × 106 CAR T cells/kg. The primary endpoint was safety; secondary endpoints included antitumor activity and pharmacokinetics. RESULTS: All patients experienced grade 3 or higher hematologic toxicity, and 75% developed cytokine release syndrome, both of which were generally manageable. Two treatment-related deaths occurred: 1 due to immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome and 1 due to intestinal fistula following rapid tumor regression in a lesion adherent to the intestinal wall. The objective response rate and disease control rate reached 33% and 63%, respectively. Eight patients achieved a partial response as their best response, 7 maintained stable disease, and 5 had progressive disease. Median progression-free survival was 57 days, and median overall survival was 190 days. Higher in vivo CAR T-cell expansion was associated with better disease control. Proof-of-concept activity was demonstrated, although response durability was limited and toxicity remains challenging. CONCLUSIONS: GCC-targeted CAR T cells demonstrated encouraging antitumor activity in heavily pretreated patients with colorectal cancer, with the initial data supporting GCC as a clinically actionable target. Further development will require dose selection, patient eligibility, and toxicity management optimization to improve the therapeutic profile.

1. 原文摘要
Pancreatic ductal adenocarcinoma (PDAC) remains a therapeutic challenge due to its dense stroma and lack of druggable targets. Through integrated bioinformatics analysis of in-house and public datasets, we systematically identified miR-21 as the most significantly upregulated oncomiR in PDAC, showing strong correlation with poor patient prognosis. RNA-targeted degradation has emerged as a promising strategy for cancer treatment, enabling precise disruption of oncogenic signaling by degrading disease-driving non-coding RNAs. Nevertheless, poor tissue penetration and insufficient tumor specificity limit its therapeutic potential in pancreatic cancer, owing to the dense fibrotic stroma and heterogeneous target expression. Herein, we developed a dual-targeting, bioresponsive Nb-RIBOTAC (Nb-Fc-Val-Cit-RIBOTAC), engineered by conjugating a cathepsin B-responsive linker to bridge an EGFR-targeting nanobody (Nb-Fc fusion) with a miR-21-specific RIBOTAC module. This rationally designed therapeutic achieved potent and selective miR-21 degradation in orthotopic PDAC models, with 60% target knockdown while completely sparing normal tissues, leading to significant tumor growth inhibition. Our study establishes a transformative paradigm bridging bioinformatic identification with precision RNA degradation technology, offering new therapeutic possibilities for PDAC treatment. The target selection strategy and modular design principles described herein may be broadly applicable to other challenging malignancies.

胰腺导管腺癌(PDAC)因致密基质和缺乏可成药靶点而难以治疗。通过对内部和公共数据集进行整合生物信息学分析,研究者系统鉴定miR-21为PDAC中最显著上调的致癌miRNA,并与患者预后不良强相关。RNA靶向降解已成为癌症治疗的有前景策略,可通过降解致病性非编码RNA精确扰乱致癌信号。然而,胰腺癌细胞致密纤维性基质和靶点表达异质性限制了其治疗潜力。本研究开发了双靶向、生物响应型Nb-RIBOTAC(Nb-Fc-Val-Cit-RIBOTAC),通过组织蛋白酶B响应性连接子将EGFR靶向纳米抗体(Nb-Fc融合)与miR-21特异性RIBOTAC模块偶联。该合理设计的治疗分子在原位PDAC模型中实现强效且选择性的miR-21降解,靶点敲低达60%,同时完全 sparing正常组织,显著抑制肿瘤生长。该研究建立了从生物信息学靶点鉴定到精准RNA降解技术的转化范式,为PDAC治疗提供了新的可能。该靶点选择策略和模块化设计原则可推广至其他难治性恶性肿瘤。

1. 原文摘要
White spot syndrome virus (WSSV) is a fatal pathogen responsible for significant economic losses in the global crustacean industry, and there are no effective commercial therapeutic drugs available for controlling the spread of WSSV. Nanobodies (Nbs) have attractive antiviral properties including small molecular size, high specificity, stable structure, and ease of production. Cell-penetrating peptide Pep-1 can serve as a vector to deliver proteins into cells. In our previous study, a nanobody named Nb24 targeting WSSV envelope protein VP28 was successfully screened using phage display technology. In this study, Nb24 was fused to Pep-1 to generate Pep-1-Nb24, and the entry efficiency of Pep-1-Nb24 and its anti-WSSV activity were evaluated in crayfish Procambarus clarkii. The results showed that Nb24 could significantly block WSSV infection in a dose-dependent manner in crayfish, and improve the survival rate of WSSV-infected crayfish. Nevertheless, the poor membrane permeability of Nb24 made it difficult to enter cells autonomously. Interestingly, Pep-1 successfully delivered Nb24 into hemocytes and tissues of the gill and hepatopancreas, and Pep-1-Nb24 had a stronger anti-WSSV activity in crayfish. Moreover, the expression of antioxidant genes SOD, CAT, GST and immune genes Lzm, Crustin, and Propo was significantly upregulation after treatment with Nb24 and Pep-1-Nb24 in WSSV-infected crayfish. The expression levels of these genes in Pep-1-Nb24 groups were higher than those in Nb24 groups. In summary, these results indicate that Pep-1-Nb24 can effectively inhibit WSSV replication, and this research may accelerate the process of Nb24 for clinical use in aquaculture.

白斑综合征病毒(WSSV)是对全球甲壳类养殖业造成重大经济损失的致命病原体,目前尚无有效的商用治疗药物控制其传播。纳米抗体(Nbs)具有小分子量、高特异性、结构稳定和易于生产等吸引人的抗病毒特性。细胞穿透肽Pep-1可作为将蛋白质递送入细胞的载体。在前期研究中,研究者通过噬菌体展示技术筛选到靶向WSSV包膜蛋白VP28的纳米抗体Nb24。本研究将Nb24与Pep-1融合表达,获得融合蛋白Pep-1-Nb24,并在克氏原螯虾中评估其进入效率和抗WSSV活性。结果显示,Nb24可剂量依赖性地显著阻断螯虾WSSV感染并提高感染存活率。然而,Nb24膜通透性较差,难以自主进入细胞。有趣的是,Pep-1成功将Nb24递送至血细胞及鳃和肝胰腺组织中,Pep-1-Nb24在螯虾中展现出更强的抗WSSV活性。此外,WSSV感染螯虾经Nb24和Pep-1-Nb24处理后,抗氧化基因SOD、CAT、GST及免疫基因Lzm、Crustin、Propo表达显著上调,且Pep-1-Nb24组表达水平高于Nb24组。总之,这些结果表明Pep-1-Nb24可有效抑制WSSV复制,该研究可能加速Nb24在水产养殖中的临床应用。

1. 原文摘要
Bulk refractive-index sensitivity is widely used to characterize localized surface plasmon resonance (LSPR) sensors, but the response of a finite biomolecular interface also depends on how that optical response is realized after surface construction. We examined this relationship across independently generated, microplate-reader-compatible immobilized gold nanoparticle (AuNP) and gold nanourchin (AuNU) architectures spanning direct-IgG coupling, Protein A/anti-glial fibrillary acidic protein (GFAP) IgG, and anti-receptor-binding domain (RBD) nanobody (Nb) workflows. Selected nanobody branches were further evaluated using receptor-omitted RBD controls and leptin challenge, and the 100 nm AuNU/Nb branch was tested in 10% pooled human serum. A fixed, non-fitted sensing-envelope calculation based on assigned parameters provided a distance-based optical reference. Bulk sensitivities spanned 57-241 nm RIU-1, with the largest value for the 100 nm AuNU ensemble. Downstream responses, however, depended on architecture and interface state. Linker loading did not consistently yield a resolvable receptor-associated step, and the 30 and 60 nm AuNP Protein A/anti-GFAP branches showed compressed GFAP-associated profiles. Anti-RBD nanobody branches produced concentration-dependent buffer responses; on the 100 nm AuNU/Nb branch, receptor-omitted RBD background remained low but non-zero and did not reproduce the larger middle-to-upper-range target response. Leptin also produced a measurable response, while the exploratory 10% serum experiment yielded small, partly non-monotonic serum-centered increments (0.12-0.28 nm). The data distinguish pre-biofunctionalization optical response from interface construction and analytical discrimination. The sensing-envelope calculations provide a conditional geometric reference for interpreting these observations.

体相折射率灵敏度广泛用于表征局域表面等离子体共振(LSPR)传感器,但有限生物分子界面的响应还取决于表面构建后光学响应的实现方式。本研究在独立制备的、微孔板读数仪兼容的固定化金纳米颗粒(AuNP)和金纳米海胆(AuNU)结构中考察了这一关系,涵盖直接IgG偶联、Protein A/抗胶质纤维酸性蛋白(GFAP)IgG以及抗受体结合域(RBD)纳米抗体(Nb)工作流程。对选定的纳米抗体分支进一步用受体缺失RBD对照和瘦素挑战进行评估,100 nm AuNU/Nb分支在10%混合人血清中进行了测试。基于设定参数的非拟合传感包络计算提供了基于距离的光学参考。体相灵敏度范围为57-241 nm RIU⁻¹,其中100 nm AuNU系综值最大。然而,下游响应取决于结构和界面状态。连接子加载并不总能产生可分辨的受体相关步骤,30和60 nm AuNP Protein A/抗GFAP分支显示GFAP相关曲线压缩。抗RBD纳米抗体分支产生浓度依赖性缓冲液响应;在100 nm AuNU/Nb分支上,受体缺失RBD背景保持较低但非零,且不能重现中-高浓度靶标的大响应。瘦素也产生了可测量响应,而探索性10%血清实验产生较小、部分非单调的血清中心增量(0.12-0.28 nm)。数据区分了预生物功能化光学响应、界面构建和分析识别。传感包络计算为这些观察提供了有条件的几何参考。

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic disabling and debilitating inflammatory disease with limited therapeutic options. OBJECTIVE: To present the primary results of the phase 2 MIRA trial, which evaluated the efficacy and safety of the IL-17A- and IL-17F-inhibiting nanobody sonelokimab in adults with moderate-to-severe HS. METHODS: MIRA was a 24-week global, randomized, prospective, parallel-group, double-blind, placebo-controlled trial. Eligible patients were randomized (2:2:2:1) to receive subcutaneous sonelokimab 120 mg, sonelokimab 240 mg, placebo, or adalimumab (active reference arm). The primary endpoint was the proportion of patients achieving HS Clinical Response 75 (HiSCR75) versus placebo at week 12 using non-responder imputation in an intention-to-treat population. RESULTS: Two hundred thirty-four patients were randomized (sonelokimab 120 mg, n=67; sonelokimab 240 mg, n=66; placebo, n=68; adalimumab active reference arm, n=33). The primary endpoint of HiSCR75 was met for both sonelokimab doses (120 mg: 43%, P<0.001; 240 mg: 35%, P=0.007) versus placebo (15%). Responses increased or were maintained through week 24. No new safety signals were identified. LIMITATIONS: MIRA was a 24-week study; ongoing phase 3 trials will assess longer-term efficacy and safety. CONCLUSIONS: Sonelokimab demonstrated high levels of clinical response in patients with moderate-to-severe HS and was well tolerated.

1. 原文摘要
Reversibly photoswitchable fluorophores are widely used in advanced bioimaging, but their design remains demanding. Here, we introduce a new series spanning the whole visible range, which results from combining a large set of fluorogens with the FAST protein scaffold. We first demonstrate that these well-established fluorescent protein labeling tags turn into negative reversible photoswitchers upon decreasing the fluorogen concentration and increasing light intensity. We then show that using not one but two fluorogens adds new responses to illumination. Thus, we obtain positive reversible photoswitchers that increase their brightness under illumination. We also generate a palette of non-covalent reversibly photoconvertible fluorescent proteins changing their fluorescence color upon illumination, a reversible behavior that still remains absent in regular fluorescent proteins. This light-induced color change opens the possibility to discriminate six spectrally similar FAST variants in live cells upon demonstrating the superiority of using multiple spectral channels for exploiting the time dependence of the fluorescence response to illumination.

1. 原文摘要
MOTIVATION: While Protein Language Models (PLMs) fine-tuned on biophysical data achieve high predictive accuracy, the physical principles underlying their predictions remain obscure. Deciphering these representations offers a unique opportunity to not only interpret model decisions but also to discover novel biophysical insights governing protein properties. Here, we present a framework using Sparse Autoencoders (SAEs) to extract mechanistic knowledge from PLMs fine-tuned for nanobody thermostability. RESULTS: We fine-tuned the ESM-2 model on the nanobody thermostability dataset, achieving superior performance compared to significantly larger state-of-the-art models. SAE analysis successfully decomposed the model's dense embeddings into sparse, interpretable features without loss of predictive accuracy. We characterized these features through both global and local analyses. Global analysis provided an aggregate map of position-dependent feature contributions, whereas local analysis identified specific residue-level patterns, including known determinants such as the VHH-tetrad and critical disulfide bonds, as well as candidate stabilizing residues. Free Energy Perturbation calculations supported the structural plausibility of selected residue-level hypotheses. These results show that SAE-based interpretation can generate testable, structurally grounded hypotheses for rational protein engineering. AVAILABILITY: The data and source code of the proposed method are available at GitHub (https://github.com/matsunagalab/paper_nanobody-thermostability-sae) and Zenodo (DOI: 10.5281/zenodo.18012027).

1. 原文摘要
The rapid evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and associated complement overactivation challenge current antiviral strategies that mainly target viral entry. This study aimed to develop dual-targeting engineered binding proteins capable of simultaneously blocking viral infection and complement activation. Two proteins, SBP10 and SBP16, were engineered by integrating an ACE2-mimicking peptide with a mannose-binding lectin (MBL) domain. Binding affinity and antiviral activity were evaluated using biochemical and functional assays, including inhibition of S protein-ACE2 interaction, neutralization of multiple SARS-CoV-2 variants, and assessment of lectin pathway-mediated complement activation. Both SBP10 and SBP16 bound the spike protein with low-nanomolar affinity and effectively blocked its interaction with ACE2. The proteins exhibited broad-spectrum neutralizing activity against several variants, including Alpha, Beta, Delta, and Omicron. Moreover, they significantly suppressed spike-induced activation of the lectin complement pathway. In vivo experiments further demonstrated that treatment with SBP10 or SBP16 markedly reduced spike protein-induced lung injury. In conclusion, SBP10 and SBP16 function as dual-targeting engineered binding proteins that inhibit viral entry while attenuating complement-mediated inflammation, highlighting a promising therapeutic strategy for controlling SARS-CoV-2 infection and its associated immune dysregulation.

1. 原文摘要
The ongoing evolution of SARS-CoV-2, particularly Omicron sublineages harboring extensive RBD mutations, compromises the effectiveness of many existing neutralizing nanobodies. Here, we present an integrated computational-experimental framework to prioritize nanobodies with favorable predicted interaction profiles across mutated RBD backgrounds and to explore their potential for biparatopic engineering. Thirty-two nanobody-RBD complexes from the Protein Data Bank were computationally screened across eight Omicron sublineages (BA.1-XBB.1.5). Selected nanobodies were then further evaluated against the Wuhan reference strain and XBB.1.5-the predominant sublineage at the onset of laboratory testing-using molecular simulations and conventional virus neutralization tests (cVNTs) performed in three biological replicates. These analyses led to the prioritization of MR17 and Sb14. In subsequent cVNT assays, MR17 showed a significantly higher neutralization titer against XBB.1.5 than against the Wuhan reference strain, whereas Sb14 showed comparable titers against both targets. A biparatopic Sb14-MR17 construct exhibited a significantly higher neutralization titer against XBB.1.5 than either monomeric nanobody. In addition, the interaction profiles of selected candidates with the emerging NB.1.8.1 RBD were evaluated computationally. Collectively, these results highlight multi-sublineage computational triage, together with targeted experimental validation, as a practical strategy for prioritizing nanobody candidates under ongoing SARS-CoV-2 antigenic drift.

1. 原文摘要
Conventional nanobody ELISAs for trace Cronobacter sakazakii in powdered infant formula suffer from random orientation and low signal output. We developed an oriented dual-modal immunoassay that combines site-specific biotinylation via a C-terminal AviTag and a peptide molecular lock, enabling controlled surface orientation while preserving nanobody structural integrity. This strategy was further integrated with phage-displayed nanobodies for multivalent amplification and both fluorescent and colorimetric readouts. The assay exhibited a broad linear range of 103-106 CFU/mL, with limits of detection (LODs) of 6.70 × 102 CFU/mL for fluorescence and 1.55 × 103 CFU/mL for colorimetry, showing improved sensitivity compared with the conventional passive adsorption-based Nb-ELISA evaluated in this study. XGBoost-based multimodal fusion improved quantitative accuracy, and SHAP analysis elucidated modality contributions. In spiked powdered infant formula samples, recoveries ranged from 92.1% to 118% with coefficients of variation below 5.98%, confirming acceptable matrix tolerance and analytical reliability.

1. 原文摘要
Over the past decades, yeast surface display (YSD) technology has emerged as a powerful biotechnological tool with broad applications in biomedicine, industrial catalysis, and environmental science. However, its efficiency, stability and applicability are often limited by proteolytic degradation during secretion in commonly used strains and steric hindrance associated with anchoring architectures. In this study, we developed a high-performance platform, "CEN-Display," using a systematic engineering strategy on the Saccharomyces cerevisiae CEN.PK2-1C strain to expand the YSD toolbox for new chassis. The host chassis was engineered by deleting key vacuolar proteases PEP4/PRB1 to suppress degradation and CAN1 to modulate membrane permeability. And the redesigned display vector incorporated a de novo designed rigid linker (>600 aa) to minimize steric hindrance. Moreover, we conducted a systematic evaluation of eight candidate GPI-anchored proteins and refined cultivation process, specifically optimizing initial inoculation density and induction timing. Eventually, we identified 28_YI as a highly efficient and stable anchor, achieving a sixfold increase in α-galactosidase display efficiency and a 63.5% enhancement in enzymatic activity relative to the conventional Aga1-Aga2 system. Furthermore, the CEN-Display platform exhibited robust compatibility and stability for displaying both the complex enzyme (β-glucosidase, BGL1) and the degradation-prone nanobody (VHH 7D12). Collectively, this work establishes a high-performance yeast surface display platform based on the CEN.PK chassis and provides a foundation for the construction and application of high-performance display systems with broad utility in protein engineering and functional screening.

1. 原文摘要
Immunofluorescence (IF) staining is widely used to visualize biomolecules in cells and tissues. Conventional IF typically relies on fluorophore-conjugated antibodies, whose preparation requires chemical modification procedures that can compromise antibody performance and incur product loss during subsequent purification. In addition, iterative immunostaining depends on harsh stripping or fluorescence-quenching treatments that may damage sample architecture and epitope integrity. Here, we present protease-cleavable nanobody-fluorescent protein fusions (NFPFs) for reversible IF staining. Unlike fluorophore-labeled antibodies, NFPFs are genetically encoded and can be produced without post-synthetic chemical modification. By incorporating a tobacco etch virus (TEV) protease cleavage site between the nanobody and fluorescent protein, we engineered HER2- and EGFR-targeting NFPFs that retained high target specificity and enabled robust, concentration-dependent immunostaining of Capan-1 cells. TEV-mediated cleavage efficiently removed the fluorescent reporter while preserving cellular morphology and antigen accessibility, allowing subsequent staining of targets. Sequential labeling of distinct receptors demonstrated the feasibility of iterative immunostaining within the same specimen. Collectively, NFPFs provide a simple, scalable, and versatile approach for molecular imaging, enabling repeated rounds of immunostaining.

1. 原文摘要
PURPOSE: Gefurulimab, a novel dual-binding nanobody targeting complement component 5 (C5), is in clinical development for anti-acetylcholine receptor antibody-positive generalized myasthenia gravis. Gefurulimab has a low molecular weight, enabling subcutaneous (SC) self-administration by autoinjector (AI) or prefilled syringe with needle safety device (PFS-SD). We compared gefurulimab pharmacokinetic (PK) exposure and safety in healthy adults following a single SC dose administered by AI versus PFS-SD. METHODS: In this phase 1, open-label, randomized, parallel-group study (NCT06208488), healthy participants aged 18 to 65 years were stratified by weight and randomized equally to 1 of 6 combination groups of device and injection site (abdomen/thigh/upper arm). Participants received a single SC dose of gefurulimab on day 1 and were assessed throughout the 92-day evaluation period. Primary endpoints were PK parameters for each device: maximum observed concentration (Cmax) and area under the serum concentration-time curve (AUCinf, AUClast). PK across injection sites, pharmacodynamics, safety, immunogenicity, and device performance were also assessed. FINDINGS: Overall, 175 participants were randomized: AI (n = 87), PFS-SD (n = 88). Geometric least squares mean ratios (90% CI) comparing AI/PFS-SD for Cmax, AUCinf, and AUClast were 97.6% (94.5-100.8), 99.6% (96.1-103.3), and 98.8% (95.2‒102.6), respectively. Secondary analyses found no meaningful differences in PK parameters across injection sites. Serum-free C5 concentrations over time, treatment-emergent adverse event (TEAE) profiles, and antidrug antibody responses were similar between cohorts. Most TEAEs were mild; none led to study discontinuation. IMPLICATIONS: SC administration of gefurulimab by AI and PFS-SD was well tolerated with comparable exposure, meeting bioequivalence criteria.

1. 原文摘要
Nanobodies, also known as single-domain antibodies or variable domains of heavy-chain-only antibodies (VHHs), are the antigen-binding domains derived from heavy-chain-only antibodies that naturally occur in camelids. Since their discovery in the early 1990s, Nanobodies have attracted significant attention in the fields of biotechnology, structural biology, diagnostics, and therapeutics. Their unique structural and biochemical properties distinguish them from conventional antibodies and offer several practical advantages as versatile modular units in next-generation biologics. We discuss the most important and useful properties of Nanobodies, including their generation, physicochemical characteristics, manufacturability, stability, immunogenicity, antigen recognition capabilities, functional modulation, and engineering flexibility. We review the development and production of multivalent and multispecific Nanobody constructs; strategies to extend their in vivo half-life; and various functional fusions, including immunotoxins, imaging agents, and cellular therapies such as CAR T cell constructs.

1. 原文摘要
Camelid variable heavy-chain (VHH) nanobodies have emerged as a promising class of single-domain antibodies with significant potential for combating bacterial and parasitic infections. Their small molecular size, high solubility, exceptional physicochemical stability, and ability to recognize cryptic or conformational epitopes inaccessible to conventional antibodies enable unique therapeutic applications. This review summarizes recent advances in the biology, mechanisms of action, engineering, and translational potential of camelid VHH nanobodies against bacterial and parasitic pathogens. In bacterial infections, nanobodies primarily function as anti-virulence agents by neutralizing toxins, inhibiting bacterial adhesion and invasion, disrupting secretion systems, preventing biofilm formation, and targeting antimicrobial resistance determinants such as β-lactamases. In protozoal diseases, they exhibit diverse mechanisms including direct killing, inhibition of host-cell invasion, disruption of surface protein trafficking, interference with metabolic pathways, and blockade of transmission stages. We further discuss current approaches for nanobody generation, recombinant production, molecular engineering, and optimization, together with challenges related to pharmacokinetics, immunogenicity, manufacturing, and clinical translation. Finally, emerging applications involving artificial intelligence-assisted nanobody design, nanotechnology-based delivery systems, One Health strategies, and outbreak preparedness are highlighted. Collectively, camelid VHH nanobodies represent a versatile and highly engineerable platform with considerable potential to address antimicrobial resistance, and accelerate the development of next-generation antimicrobial therapeutics.

1. 原文摘要
Thrombotic thrombocytopenic purpura (TTP) is a rare and rapidly life-threatening thrombotic microangiopathy. Disseminated microvascular thrombosis and resulting ischemia are the critical events determining outcome, if left untreated. The pathogenic hallmark is a severe deficiency of the plasma metalloprotease ADAMTS13, resulting in impaired cleavage of ultra-large von Willebrand factor (vWF) multimers leading to platelet aggregation. The vast majority of TTP cases are acquired and immune-mediated, depleting ADAMTS13 through autoantibodies. In contrast, congenital deficiency of ADAMTS13 affects a minority of patients. Measurement of ADAMTS13 activity is the cornerstone for diagnosis and implementation of treatment. However, clinical prediction scores support early therapeutic decision-making when results are pending. Plasma exchange, immunosuppression and more recently, the anti-vWF nanobody caplacizumab, are the central pillars for treatment of immune-mediated TTP. Caplacizumab prevents microvascular thrombosis during the acute episode but does not address the autoimmune-mediated ADAMTS13 depletion, underscoring the importance of plasma exchange and immunosuppression. Congenital TTP was previously treated using ADAMTS13 replacement through regular plasma infusions, but provision of recombinant ADAMTS13 has recently transformed treatment in these patients. Despite major advances, relapse remains a persistent threat for patients, making structured, long-term follow-up necessary. Diagnostic advances may help improve relapse prediction and corresponding therapeutic management. This review summarizes current concepts in the pathophysiology, diagnosis, clinical management of TTP and highlights recent therapeutic advancements and future challenges.

1. 原文摘要
Despite a myriad of medicinal breakthroughs in lipid-lowering and antithrombotic therapies, cardiovascular diseases (CVDs) are still the main killers worldwide. According to the consolidated scientific evidence, atherosclerosis, ischemic heart disease, and other vascular pathologies are attributed to endothelial dysfunction and vascular inflammation. The standard treatments' failure to adequately control the inflammatory and endothelial pathways has led researchers to biologics that are molecularly specific. Nanobodies (Nbs) are single-domain antibody fragments obtained from camelid heavy-chain antibodies. Due to their small size, good tissue penetration, and stability, they are regarded as therapeutic agents and diagnostic tools. This paper is focused on the current and potential future uses of nanobodies in the treatment of endothelial activation, the blockade of adhesion molecule expression, and the management of cytokine-induced vascular inflammation. The literature shows that diagnostic nanobody tracers achieve high accuracy for vascular inflammation imaging, yet therapeutic Nbs exist only in preclinical stages. PANX1-blocking Nbs show promise for treating ischemia-reperfusion injury, and IL-1β-targeted Nbs demonstrate effectiveness in reducing hypoxia-induced damage to endothelial cells. The therapeutic potential of Nbs has been proven by caplacizumab, which functions as an anti-vWF nanobody, but its approved medical use exists only for hematologic disorders. The therapeutic potential of Nbs remains unexplored for ROS, ox-LDL, AT1R, and chemokines CCL2 and CCL5 because researchers have not developed corresponding nanobody-based interventions. The review demonstrates how nanobody engineering advances combined with current molecular knowledge create a promising yet underdeveloped therapeutic area for cardiovascular medicine, which could use precise biologic treatments to restore vascular equilibrium and fight inflammation, thus transforming future CVD treatment approaches.

1. 原文摘要
Protein scaffolds are being developed as novel non-antibody-binding platforms to address significant challenges in traditional cancer immunotherapy, including high production costs, limited tumor penetration, immune-related toxicity, and therapeutic resistance. Scaffolds, which consist of Affibodies, DARPins, Anticalins, Monobodies (Adnectin), Knottins, and Avimers, are structurally stable, small in size, and serve as extensively modified proteins, offering higher solubility, rapid clearance from unwanted tissues, and effective recombinant production compared with monoclonal antibodies (mAbs). Their modular design enables targeted engagement of tumor-associated antigens, immune checkpoints (including CTLA-4, PD-1/PD-L1, and LAG-3), and elements of the tumor microenvironment (TME), thereby enhancing targeted immune activation while preventing systemic side effects. Engineering approaches that employ display technologies such as phage/yeast/ribosome displays, directed evolution, and rational computational design have contributed to scaffold-affinity tuning, multivalency, and half-life extension via PEGylation, albumin fusion, and FC linkage. Mechanistically, these scaffolds suppress oncogenic signalling pathways, restore T-cell activity through checkpoint blockade, regulate cytokine signalling, and enable high-resolution tumor imaging, as exemplified by KRAS-binding DARPins and HER2-targeted affibody ABY-025. Potential challenges remain, including rapid renal clearance, risk of off-target binding, and immunogenicity. Future developments, including AI-assisted scaffold modification, multi-functional immunomodulatory structures, and their integration with personalized neoantigen treatments. Protein scaffolds are a rapidly emerging therapeutic class with immense potential to revolutionize targeted cancer immunotherapy and personalized diagnostics.

1. 原文摘要
The design of antigen-binding domains (binders) is emerging as a decisive frontier in chimeric antigen receptor (CAR)-T cell engineering. Rather than serving as passive recognition elements, binders actively shape antigen selectivity, signaling thresholds, exhaustion propensity, persistence, and toxicity. We propose that optimal CAR performance requires a multidimensional design strategy. Success cannot be achieved by maximizing a single variable like affinity. Designers must instead integrate epitope position, binding kinetics, avidity, molecular geometry, and biophysical stability. In this review, we synthesize recent advances showing how these parameters collectively govern immunological synapse formation, antigen-density discrimination, and functional durability. Importantly, we highlight that the consequences of binder design are increasingly evident not only in mechanistic and preclinical studies, but also in real-world clinical translation and commercial trajectories. We further examine how the binder landscape has expanded beyond conventional scFvs to include VHHs, monobodies, DARPins, D-domains, peptides, natural ligands, TCR-mimic binders, and de novo AI-designed proteins. Together, these advances support a shift from empirical binder selection to rational binder orchestration as a foundational principle for next-generation CAR-T immunotherapy.
