1. 原文摘要

BACKGROUND AND AIMS: Tumor necrosis factor-α (TNF-α) is a well-characterized causal mediator in the pathogenesis of acute liver failure (ALF). Despite the efficacy of TNF-α inhibitors (e.g., antibodies and Fc-fused receptor proteins) in animal models, clinic translation has not been successful so far, largely due to sustained repression of TNF-α signaling and Fc-mediated deleterious immune responses. To address these obstacles, we aim to develop a new modality targeting TNF-α by employing lysosome-targeting protein degradation technology. METHODS: Murine Niemann-Pick type C 2 (NPC2) or a mutated form of human insulin-like growth factor 2 (IGF2) (Y27L, IGF2m) was fused to the C-terminus of a TNF-α-targeting nanobody (Nb) via a peptide linker. The ability of Nb-NPC2 and Nb-IGF2m to deliver TNF-α into the lysosomal compartment for degradation, thereby inhibiting TNF-α-induced apoptosis, was examined in IGF2R-expressing cell lines. ALF models induced by co-injection of D-Galactosamine (GalN) with human TNF-α or LPS were used to evaluate the protective efficacy of the fusion proteins. RESULTS: Nb-NPC2 potently suppressed TNF-α-induced cellular apoptosis via the interaction between mannose-6-phosphate (M6P)-bearing NPC2 and IGF2R. Mechanistically, the fusion protein actively hijacked TNF-α to be transported into the lysosome for degradation. Nb-NPC2 administration protected mice from ALF-induced lethality and tissue damage by rapidly clearing TNF-α in circulation. Furthermore, a non-glycosylated version (i.e., Nb-IGF2m) exhibited comparable effects in vitro and in vivo. CONCLUSIONS: Nb-NPC2 (IGF2m) represents a novel avenue with therapeutic potential for ALF, primarily via lysosome-targeting degradation of TNF-α. IMPACT AND IMPLICATIONS: Acute liver failure is a life-threatening inflammatory disease in which TNF-α serves as a central mediator to trigger hepatocyte death, thereby causing vascular dysfunction and liver injury. However, attempts to block TNF-α using antibodies or Fc-fusion proteins in ALF patients have provided no survival benefit to date, largely attributable to sustained suppression of TNF-α as well as Fc-mediated deleterious immune reactions. Our study proposed a novel modality by employing a lysosome-targeting degradation strategy that rapidly cleared TNF-α in circulation and consequently exhibited protective efficacy in ALF mouse models. Given the huge unmet medical need for ALF therapy, the therapeutic potential of this avenue deserves further validation.

背景与目的:肿瘤坏死因子-α(TNF-α)是急性肝衰竭(ALF)发病机制中明确的致病介质。尽管TNF-α抑制剂(如抗体和Fc融合受体蛋白)在动物模型中有效,但其临床转化迄今未获成功,主要原因是TNF-α信号持续抑制以及Fc介导的有害免疫反应。为克服这些障碍,本研究旨在利用溶酶体靶向蛋白降解技术开发一种靶向TNF-α的新 modality。方法:将小鼠Niemann-Pick C2型蛋白(NPC2)或突变型人胰岛素样生长因子2(IGF2m,Y27L)通过肽连接子融合于抗TNF-α纳米抗体(Nb)的C端。在表达IGF2受体的细胞系中检测Nb-NPC2和Nb-IGF2m将TNF-α递送至溶酶体降解、从而抑制TNF-α诱导凋亡的能力。采用D-半乳糖胺(GalN)联合人TNF-α或LPS诱导的ALF模型评价融合蛋白的保护效力。结果:Nb-NPC2通过含甘露糖-6-磷酸(M6P)的NPC2与IGF2R的相互作用,有效抑制TNF-α诱导的细胞凋亡。机制上,该融合蛋白主动将TNF-α劫持并转运至溶酶体降解。Nb-NPC2给药可通过快速清除循环中TNF-α,保护小鼠免受ALF致死和组织损伤。此外,非糖基化版本Nb-IGF2m在体外和体内表现出相当效果。结论:Nb-NPC2(IGF2m)通过溶酶体靶向降解TNF-α,代表了一种具有治疗ALF潜力的新途径。

1. 原文摘要

Accurate identification of epitope residues is essential for developing biopharmaceuticals and understanding the mechanisms of immune recognition. However, experimental approaches for residue-level epitope mapping remain time-consuming and labor-intensive, while accurate computational prediction of protein-protein interfaces remains challenging. Here, we present MAXTIA, a high-throughput kinetic screening platform that integrates cell-free protein synthesis with high-throughput surface plasmon resonance and demonstrate its application to alanine scanning-based functional epitope mapping. This workflow enables the rapid preparation and kinetic characterization of up to 384 protein variants, allowing the identification of functional epitope residues within 3 days while simultaneously providing binding affinity and kinetic parameters (KD, kon, and koff). We applied MAXTIA to map the epitope of the single-domain antibody (VHH) N1 against the pentraxin domain of neuronal pentraxin-2 (NP2 PTX). Alanine substitutions that cause substantial affinity losses clustered within a localized region on the AlphaFold3-predicted NP2 PTX structure, defining a functional epitope site. These residues closely matched the interface observed in the NP2 PTX-VHH N1 crystal structure, validating the accuracy of MAXTIA. Beyond epitope identification, MAXTIA provides a simple and versatile platform for the quantitative analysis of protein-protein interactions, including high-throughput screening of antibody variants for affinity optimization. This approach should accelerate biopharmaceutical development and facilitate mechanistic studies of molecular recognition.

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。然而,其疗效受肿瘤微环境(TME)空间异质性的严重限制,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仍是主要挑战。本研究开发了一种基于适配体修饰声学细菌(AAB)的超声引导瘤内递送方法。AAB经基因工程改造表达气囊(GVs)以增强超声对比度,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-坏死肿瘤龛,使这些免疫抑制龛可通过超声造影(CEUS)成像。在AAB引导的CEUS成像下,经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)被准确注射至缺氧-坏死区域内或外。注射于这些区域外可产生显著更优的抗肿瘤效果。该增强疗效源于存活肿瘤细胞上功能性CD47靶标的保留,同时强烈诱导M1巨噬细胞极化和肿瘤内促炎免疫微环境。本研究为克服肿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

The reliable detection and quantification of adeno-associated virus serotype 9 (AAV9) is crucial for gene therapy development and quality control. This work presents a significant advancement by developing a novel, nanobody-based photoelectrochemical (PEC) immunosensor for the highly sensitive and specific detection of AAV9. The core is a laser-synthesized multiphase TiO2 heterojunction photoanode fabricated directly on a titanium substrate. This one-step, mask-free laser processing technique ensures excellent material consistency and superior photocurrent response, overcoming the batch-to-batch variability associated with traditional electrode modification methods. The sensing interface is further engineered by immobilizing a high-affinity anti-AAV9 nanobody, which offers minimal steric hindrance and enhanced epitope accessibility compared to conventional antibodies. The synergistic integration of a high-performance multiphase photoactive material with a biological recognition element, resulting in a satisfactory sensing platform. The fabricated immunosensor demonstrates a wide linear detection range from 5 × 107 to 1 × 1010 vg/mL (vg/mL: viral genomes per milliliter) for AAV9, with a remarkably low calculated detection limit (LOD) of 1 × 107.2 vg/mL and limit of quantitation (LOQ) of 3 × 107.2 vg/mL. To our knowledge, this represents the first successful application of an AAV9-specific nanobody within a PEC biosensing platform. This study not only provides a powerful tool for virological analysis but also establishes a versatile framework that can be adapted for detecting other viral targets by exchanging the nanobody probe, showcasing broad potential in biomedical diagnostics.

1. 原文摘要

The SARS-CoV-2 (SARS2) and SARS-CoV (SARS1) viruses pose significant threats due to their high mutation rates and potential for cross-species transmission, which has rendered many antibodies ineffective. To counter potential future emergences of novel SARS-like viruses, it is imperative to develop nanobodies with broad-spectrum neutralizing capacity. Here, we employed an alternating immunization strategy in alpacas using SARS1 and SARS2 RBDs to generate cross-reactive nanobodies. Four crossing-binding nanobodies (aSR29, aSR196, aSR347, and aSR348) were identified, exhibiting high affinities for SARS1/SARS2 RBDs and Omicron subvariants. Structural analysis revealed that aSR29 targets a cryptic, highly conserved epitope at the inner base of the RBD, a region shielded from conventional antibodies by steric hindrance, efficiently neutralizing SARS1, SARS2, and multiple Variants of Concern (VOCs), including XBB.1.5 and BQ.1.1. Building on this unique binding mode, we engineered a bispecific fusion protein, aSR29-ACE2-Fc. This construct synergistically combines high-affinity RBD binding with the steric blockade of viral attachment, resulting in a 33-fold increase in neutralization potency against SARS2 and enhanced resilience against immune escape. Our findings validate an efficient strategy for eliciting broad-spectrum nanobodies and demonstrate the therapeutic potential of VHH-ACE2 fusion proteins against current and future SARS-like viruses.IMPORTANCEThe continued evolution of SARS-CoV-2 has rendered most existing antibodies ineffective, highlighting the urgent need for broad-spectrum countermeasures against current and future SARS-like viruses. Here, we developed an alternating immunization strategy to generate nanobodies that target a hidden, highly conserved region on the viral spike protein. One such nanobody, aSR29, potently neutralizes diverse variants, including XBB.1.5 and BQ.1.1. By fusing aSR29 with the viral receptor ACE2, we created a bispecific molecule that blocks viral entry through two independent mechanisms, achieving a 33-fold increase in neutralization potency. This work provides a practical and scalable strategy for pandemic preparedness, demonstrating that engineered nanobody-ACE2 fusions can serve as effective broad-spectrum therapeutics against emerging SARS-like viruses.

SARS-CoV-2(SARS2)和SARS-CoV(SARS1)因其高突变率和跨物种传播潜力而构成重大威胁,使许多抗体失效。为应对未来可能出现的新型SARS样病毒,开发具有广谱中和能力的纳米抗体势在必行。本研究采用羊驼SARS1和SARS2受体结合域(RBD)交替免疫策略产生交叉反应性纳米抗体。鉴定出四种交叉结合纳米抗体(aSR29、aSR196、aSR347和aSR348),对SARS1/SARS2 RBD和Omicron亚变体表现出高亲和力。结构分析显示,aSR29靶向RBD底部内侧一个隐蔽且高度保守的表位,该表位因空间位阻被传统抗体遮蔽。aSR29能有效中和SARS1、SARS2及多种关注变体(VOC),包括XBB.1.5和BQ.1.1。基于这种独特结合模式,我们构建了双特异性融合蛋白aSR29-ACE2-Fc。该构建体将高亲和力RBD结合与病毒附着的立体阻断协同结合,使对SARS2的中和效力提高33倍,并增强了对免疫逃逸的抵抗能力。研究结果验证了诱导广谱纳米抗体的高效策略,并展示了VHH-ACE2融合蛋白对抗当前和未来SARS样病毒的治疗潜力。

1. 原文摘要

Nanozymes are known for their exceptional stability under extreme pH conditions, yet this property has never been exploited to overcome practical analytical limitations. Here, we report the first utilization of the extreme acid tolerance to address a long-standing challenge in wash-free assays - background signal caused by endogenous peroxidases. By performing in situ signal amplification at pH 1.0, we selectively inactivate natural peroxidases while preserving sufficient catalytic activity of Au@Pt nanozyme, thereby eliminating false-positive signals without additional washing steps. We applied this strategy to lateral flow immunoassay (LFIA) using monoclonal antibodies and nanobodies for the detection of paraquat in spinach characterized by high endogenous peroxidase activity. Under standard pH conditions, strong background interference prevented reliable visual readout. In contrast, low-pH amplification completely suppressed matrix-induced background, significantly improved the signal-to-noise ratio, and enabled detection limits (60 pg/mL) unachievable with conventional protocols and yielded satisfactory paraquat recoveries of 90-130% This work establishes a new design paradigm in biosensing and chemical engineering: instead of avoiding harsh conditions, they can be served on purpose to gain selectivity against biological background.

纳米酶以其在极端pH条件下的卓越稳定性而闻名,但这一特性尚未被用于克服实际分析局限性。本研究首次利用其极端酸耐受性解决免洗测定中长期存在的背景信号问题——由内源性过氧化物酶引起的背景信号。通过在pH 1.0下进行原位信号放大,我们选择性灭活天然过氧化物酶,同时保留Au@Pt纳米酶足够的催化活性,从而无需额外洗涤步骤即可消除假阳性信号。我们将该策略应用于侧流免疫层析(LFIA),使用单克隆抗体和纳米抗体检测菠菜中高内源性过氧化物酶活性的百草枯。在标准pH条件下,强背景干扰阻碍了可靠的目视判读。相反,低pH放大完全抑制了基质诱导的背景,显著提高了信噪比,实现了传统方案无法达到的检测限(60 pg/mL),回收率为90-130%。这项工作为生物传感和化学工程领域建立了一种新设计范式:不必回避严苛条件,反而可以有目的地利用它们来获得针对生物背景的选择性。

1. 原文摘要

Muscle cramps are among the most common acute complications of hemodialysis (HD), often occurring even in the absence of electrolyte disturbances. Most cramps are painful and may cause patients to fear future dialysis sessions. We hypothesized that susceptibility to muscle cramps may be related to impaired skeletal muscle myokine secretion. No significant differences in pre-dialysis myokine levels were observed between patients with and without muscle cramps (myostatin 36.2 vs. 86.9 (p = 0.09), fibronectin type III domain-containing protein 5 (FNDC5) 0.6 vs. 0.6 (p = 0.61), interleukin-6 (IL-6) 2.4 vs. 2.0 (p = 0.4). However, after adjustment for lean tissue mass (LTM) and lean tissue index (LTI), myostatin levels were significantly lower in patients with cramps (0.80 [0.35-1.84] vs. 1.49 [0.45-6.31], respectively, (p = 0.048) for LTM, and 2.26 [1.04-4.06] vs. 3.89 [1.52-19.47], respectively, (p = 0.04) for LTI). In multivariable logistic regression analysis, log2-transformed myostatin concentration was independently and inversely associated with muscle cramps after adjustment for dialysis vintage, body mass index (BMI), and extracellular water. No association was found between muscle cramps and ultrafiltration volume or serum sodium and potassium levels. The study included 67 hemodialysis patients (HD patients), of whom 39 experienced repeated muscle cramps during dialysis. Muscle cramps were defined as painful involuntary muscle contractions lasting more than one minute during or shortly after a dialysis session. Plasma levels of myokines-myostatin, FNDC5, and IL-6-were assessed. Pre-dialysis myostatin, but not FNDC5 or IL-6, was independently associated with the occurrence of intradialytic muscle cramps. Further studies are needed to confirm its clinical utility.

肌肉痉挛是血液透析(HD)最常见的急性并发症之一,即使在没有电解质紊乱的情况下也常发生。大多数痉挛疼痛,并可能导致患者恐惧未来的透析治疗。我们假设肌肉痉挛的易感性与骨骼肌肌因子分泌受损有关。有痉挛和无痉挛患者的透析前肌因子水平无显著差异(肌肉生长抑制素36.2 vs. 86.9,p=0.09;III型纤连蛋白结构域蛋白5(FNDC5)0.6 vs. 0.6,p=0.61;白细胞介素-6(IL-6)2.4 vs. 2.0,p=0.4)。然而,在调整瘦体组织质量(LTM)和瘦体组织指数(LTI)后,痉挛患者的肌肉生长抑制素水平显著降低(LTM调整后:0.80 [0.35-1.84] vs. 1.49 [0.45-6.31],p=0.048;LTI调整后:2.26 [1.04-4.06] vs. 3.89 [1.52-19.47],p=0.04)。在多变量logistic回归分析中,log2转换的肌肉生长抑制素浓度在调整透析龄、体重指数(BMI)和细胞外水分后与肌肉痉挛独立负相关。未发现肌肉痉挛与超滤量或血清钠、钾水平相关。研究纳入67名血液透析患者,其中39名在透析期间反复肌肉痉挛。血浆肌因子(肌肉生长抑制素、FNDC5和IL-6)被评估。透析前肌肉生长抑制素(而非FNDC5或IL-6)与透析中肌肉痉挛发生独立相关。需要进一步研究确认其临床效用。

3. 摘要层面解读

研究对象:本研究为临床观察性研究,探讨血液透析患者肌肉痉挛与肌因子(包括FNDC5)的关系。

支架类型:本研究并非以FN3/monobody等工程化蛋白支架为核心,仅在肌因子检测中提到FNDC5(III型纤连蛋白结构域蛋白5)。按周报主题分类归入FN3/monobody标签,但实际属于临床生物标志物研究。

靶点:肌肉生长抑制素(myostatin)、FNDC5、IL-6。

应用方向:血液透析并发症的生物标志物研究。

主要方法:67例血液透析患者队列 → 血浆肌因子检测 → 多变量logistic回归分析肌肉痉挛危险因素。

主要发现:

  • 肌肉生长抑制素水平与透析中肌肉痉挛独立负相关;
  • FNDC5和IL-6与肌肉痉挛无显著关联;
  • 该关联在调整LTM/LTI后仍然显著。

为什么值得关注:虽然该研究并非工程化蛋白支架研究,但其提及的FNDC5属于III型纤连蛋白结构域蛋白家族,与FN3/monobody支架有结构名称上的关联。作为临床生物标志物研究,其优先级较低(B级)。

1. 原文摘要

Antiretroviral therapy (ART) has proven effective in suppressing HIV-1 replication, but further development of HIV-1 inhibitors is continually driven by the challenge of drug resistance and viral adaptation. The HIV-1 capsid is a promising target for treatment due to its high sequence conservation as well as its crucial role in the viral life cycle. Recently, we have developed a novel capsid-targeting biologic that prevents HIV-1 replication by efficient degradation of newly synthesized capsid. Here, we have investigated the sensitivity to viral escape as well as the breadth of this biologic against HIV-1 subtypes. The capsid-targeting biologic efficiently blocked replication of different primary HIV-1 isolates, and continuous exposure of these viruses to the biologic resulted in viral breakthrough of two out of ten primary HIV-1 isolates tested. Notably, the breakthrough variants did not have amino acid changes in the nanobody epitope but primarily in the matrix region. The breakthrough variants remained sensitive to the biologic albeit to a lesser extent. In the absence of the biologic, breakthrough variants showed increased replication kinetics when compared to their parental virus, suggesting that adaption to the biologic is likely due to the increased viral production and that the target area of the biologic is too conserved for actual escape. This is further underscored by the broad specificity of the biologic as importantly the biologic blocked infection of different HIV-1 subtypes that occur worldwide (A, B, C, D, CRF01_AE, CRF02_AG). These results demonstrate the broad neutralization potential of anti-capsid biologics with a high barrier to resistance, making capsid-targeting inhibitors important for novel antiretroviral drug strategies worldwide.

抗逆转录病毒治疗(ART)在抑制HIV-1复制方面已证明有效,但耐药性和病毒适应性的挑战不断推动HIV-1抑制剂的进一步开发。HIV-1衣壳由于其高序列保守性及其在病毒生命周期中的关键作用,是治疗的有前景靶点。最近,我们开发了一种新型靶向衣壳的生物制剂,通过有效降解新合成的衣壳来阻止HIV-1复制。本研究进一步研究了该生物制剂对病毒逃逸的敏感性及其对HIV-1亚型的广谱性。该靶向衣壳生物制剂有效阻断了不同原代HIV-1分离株的复制,持续暴露后10种原代HIV-1分离株中有2种出现病毒突破。值得注意的是,突破变体在纳米抗体表位没有氨基酸改变,而主要发生在基质区。突破变体仍对生物制剂敏感,尽管程度较低。在没有生物制剂的情况下,突破变体与其亲本病毒相比表现出更快的复制动力学,提示对生物制剂的适应可能是由于病毒产量增加,而生物制剂的靶区过于保守以至于无法真正逃逸。该生物制剂的广谱特异性进一步强调了这一点,重要的是,它阻断了全球流行的不同HIV-1亚型(A、B、C、D、CRF01_AE、CRF02_AG)的感染。这些结果证明了抗衣壳生物制剂具有广谱中和潜力和高耐药屏障,使靶向衣壳抑制剂成为全球新型抗逆转录病毒药物策略的重要组成部分。

1. 原文摘要

UNLABELLED: Human immunodeficiency virus 1 (HIV-1) remains a global health burden affecting over 39 million people worldwide, with approximately one million new infections occurring each year. Sexual transmission remains the predominant route of HIV-1 acquisition, during which the virus crosses mucosal barriers and interacts with host immune cells to facilitate infection. Dendritic cells (DCs) contribute to systemic viral spread and seeding of reservoirs by efficiently capturing HIV-1, leading to infection and subsequent transmission of the virus to CD4+ T cells. Siglec-1 (CD169) is a key receptor involved in HIV-1 capture, and its blockade may help prevent viral transmission. Here, we used newly developed single-domain antibodies, also known as nanobodies, against Siglec-1 as a candidate inhibitor to limit HIV-1 transmission. Using a Siglec-1-overexpressing cell line, we demonstrated that these nanobodies specifically blocked Siglec-1-mediated HIV-1 binding and transmission. Extending these findings to a more physiologically relevant context, the anti-Siglec-1 nanobodies neither induced immune nor cellular activation in DCs, indicating a favorable safety profile for functional applications. Most notably, the anti-Siglec-1 nanobody 2C2 effectively blocked HIV-1 binding as well as infection of DCs. Moreover, both replication-dependent and replication-independent HIV-1 transmission by DCs was also abrogated by the nanobody. Our findings not only underscore the relevance of Siglec-1 in HIV-1 capture but also highlight the therapeutic potential of utilizing host-targeting strategies against infectious diseases. IMPORTANCE: Sexual transmission is the main route of human immunodeficiency virus 1 (HIV-1) infection, and novel interventions are needed to prevent this crucial first step. Mucosal dendritic cells play a key role by capturing HIV-1 via attachment receptors, leading to dendritic cell infection and subsequent transmission to T cells, thereby facilitating viral spread and establishment of infection. Here, we show that small, highly specific nanobodies targeting the attachment receptor Siglec-1 strongly interfere with this early stage of HIV-1 transmission. Siglec-1 nanobodies prevented HIV-1 binding to and infection of dendritic cells, thereby blocking transmission to T cells without inducing unwanted immune activation. Together, these findings identify Siglec-1 nanobodies as promising interventions and support the development of host-directed nanobody-based strategies to reduce HIV-1 spread.

HIV-1仍是全球健康负担,影响全球超过3900万人,每年约新增100万感染。性传播仍是HIV-1感染的主要途径,期间病毒穿越黏膜屏障并与宿主免疫细胞相互作用以促进感染。树突状细胞(DCs)通过有效捕获HIV-1,导致感染并随后将病毒传播给CD4+ T细胞,从而促进系统性病毒传播和储库形成。Siglec-1(CD169)是参与HIV-1捕获的关键受体,其阻断可能有助于预防病毒传播。本研究使用新开发的抗Siglec-1单域抗体(纳米抗体)作为限制HIV-1传播的候选抑制剂。使用Siglec-1过表达细胞系,我们证明这些纳米抗体特异性阻断Siglec-1介导的HIV-1结合和传播。将结果扩展至更生理相关的环境,抗Siglec-1纳米抗体既不诱导DCs的免疫激活也不诱导细胞激活,提示良好的功能应用安全性。最值得注意的是,抗Siglec-1纳米抗体2C2有效阻断了HIV-1结合以及DCs感染。此外,DCs依赖复制和不依赖复制的HIV-1传播也被该纳米抗体消除。我们的发现不仅强调了Siglec-1在HIV-1捕获中的相关性,还突出了利用宿主靶向策略治疗感染性疾病的潜力。

1. 原文摘要

UNLABELLED: Influenza B virus (IBV) exhibits antigenic diversity and significantly contributes to the annual burden of influenza-related disease, posing substantial impacts on global public health and the economy. In this study, we focused on the neuraminidase (NA) of IBV, immunized an alpaca with tetrameric IBV NA, and identified a series of nanobodies with a common feature of the "DYR" motif in CDR3, exhibiting broad inhibitory activity against diverse NAs of IBV. Among these, the most potent VHH5 broadly inhibits NA from multiple representative strains across ancestral, B/Yamagata/16/88-like, and B/Victoria/2/87-like lineages. Moreover, fusing VHH5 to a human immunoglobulin G1 Fc domain significantly increased its antiviral potency in vitro, with the 50% inhibitory concentration in the low nanomolar range. Structural modeling and molecular dynamics simulations revealed that the "DYR" motif within the elongated CDR3 loop of VHH5 penetrates the catalytic pocket and engages the highly conserved catalytic site of IBV NA. Experimental mutagenesis analysis of the predicted interface further supported this binding model. Furthermore, the VHH5-Fc protects mice from the lethal challenge with a high dose of the IBV-2024 virus in both prophylactic and therapeutic settings. Our findings highlight the potential of the Fc-fused VHH5 antibody in controlling influenza B virus infections. IMPORTANCE: Although influenza B viruses (IBVs) account for a substantial proportion of seasonal influenza virus infections, they have received comparatively less research attention. The small size and flexible binding modes of nanobodies enable them to access cryptic or recessed epitopes, supporting their development as potent clinical therapeutics. Here, we report the identification of VHH5, a nanobody targeting conserved residues within the neuraminidase active site of the influenza B virus, conferring broad inhibitory activity. Moreover, Fc-fused VHH5 enhanced antiviral potency in vitro and provided robust protection against lethal IBV challenge in mice. Together, these findings establish VHH5-Fc as a promising therapeutic candidate with potent and broad-spectrum activity against antigenically diverse IBV strains.

乙型流感病毒(IBV)表现出抗原多样性,显著贡献于年度流感疾病负担,对全球公共卫生和经济造成重大影响。本研究聚焦IBV的神经氨酸酶(NA),用四聚体IBV NA免疫羊驼,鉴定出一系列在CDR3中具有共同'DYR'基序、对IBV多种NA具有广谱抑制活性的纳米抗体。其中,最强的VHH5广谱抑制来自祖先系、B/Yamagata/16/88样和B/Victoria/2/87样谱系的多个代表性毒株的NA。此外,将VHH5与人免疫球蛋白G1 Fc结构域融合显著增强了其体外抗病毒效力,50%抑制浓度处于低纳摩尔范围。结构建模和分子动力学模拟显示,VHH5 elongated CDR3环中的'DYR'基序插入催化口袋并与IBV NA高度保守的催化位点结合。预测界面的实验突变分析进一步支持这一结合模型。此外,VHH5-Fc在预防和治疗的设置下均能保护小鼠免受高剂量IBV-2024病毒致死挑战。我们的发现突出了Fc融合VHH5抗体控制乙型流感病毒感染的潜力。

1. 原文摘要

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a beta-coronavirus, caused the recent global Coronavirus Disease 2019 (COVID-19) pandemic. Among the virus-encoded proteins, the surface spike (S) protein is critical for viral entry, membrane fusion, and pathogenesis, and its receptor-binding domain (RBD) initiates viral entry by binding to a cellular receptor. This makes the S an important therapeutic target for COVID-19. SARS-CoV-2 mutates frequently, giving rise to five major variants of concern, among which the Omicron variant and its subvariants are less sensitive to current therapeutic antibodies. The first part of this review describes the main protein constituents of SARS-CoV-2 and their functions, the S protein-mediated viral entry and fusion processes, and the main SARS-CoV-2 variants. Nanobodies are single-domain antibodies with high target-binding affinity, strong stability, and low production costs, whose small size facilitates their access to protein regions that are inaccessible to conventional antibodies. Thus, in the second part, we comprehensively review SARS-CoV-2-targeting nanobodies, including those that bind specifically to the RBDs of the S proteins, non-RBD S proteins, and non-S proteins of variants and subvariants of SARS-CoV-2, with the hope that this information will be valuable for the generation of novel SARS-CoV-2-targeting nanobodies with improved potency against COVID-19.

严重急性呼吸综合征冠状病毒2(SARS-CoV-2)是一种β冠状病毒,引发了最近的2019冠状病毒病(COVID-19)全球大流行。在病毒编码蛋白中,表面刺突(S)蛋白对病毒进入、膜融合和致病至关重要,其受体结合域(RBD)通过与细胞受体结合启动病毒进入。这使得S蛋白成为COVID-19治疗的重要靶点。SARS-CoV-2频繁突变,产生五种主要关注变体,其中Omicron变体及其亚变体对当前治疗抗体敏感性降低。本综述第一部分描述了SARS-CoV-2的主要蛋白组成及其功能、S蛋白介导的病毒进入和融合过程以及主要SARS-CoV-2变体。纳米抗体是具有高靶标结合亲和力、强稳定性和低生产成本的单域抗体,其小尺寸有利于进入传统抗体无法接近的蛋白区域。因此,第二部分全面综述了靶向SARS-CoV-2的纳米抗体,包括特异性结合S蛋白RBD、非RBD S蛋白以及SARS-CoV-2变体和亚变体非S蛋白的纳米抗体,希望这些信息对开发具有更强COVID-19效力的新型SARS-CoV-2靶向纳米抗体有价值。

1. 原文摘要

This paper provides a critical review of pectinases, focusing on structural diversity, advances in production technologies, industrial limitations, and emerging optimization strategies. In addition to the canonical right-handed parallel β-helix fold, several source-dependent structural features are highlighted, including Fn3-like accessory domains in bacterial enzymes, plant PME pro-domains in pectin methylesterases (PMEs), and naturally occurring bifunctional enzymes that couple de-esterification with depolymerization. Recent progress in pectinase development is also summarized, encompassing solid-state fermentation using agro-industrial residues, heterologous expression systems, protein engineering, and modern immobilization platforms, all of which contribute to improved enzyme yield, stability, and reusability. Two major industrial constraints remain prominent: the incomplete degradation of highly methyl-esterified pectin and the limited stability of enzymes under harsh operational conditions, including elevated temperature, extreme pH, solvent exposure. This review further emphasizes that effective solutions increasingly rely on multidisciplinary integration, including enzyme consortium design, bifunctional or co-expression systems enabling cascade reactions, sequence- and structure-guided engineering approaches such as directed evolution, advanced immobilization strategies, and sustainable low-cost fermentation substrates. These developments position pectinases as biocatalysts for greener and more efficient processes across food, fiber, and health-related industries.

2. 摘要中文翻译

本文对果胶酶进行了批判性综述,聚焦结构多样性、生产技术进展、工业局限性和新兴优化策略。除经典的右手平行β-螺旋折叠外,还强调了多种来源依赖性结构特征,包括细菌酶中的Fn3样辅助结构域、植物果胶甲酯酶(PMEs)中的PME前结构域,以及天然存在的将脱酯化与解聚偶联的双功能酶。综述还总结了果胶酶开发的最新进展,包括利用农业工业残渣进行固态发酵、异源表达系统、蛋白工程和现代固定化平台,这些都有助于提高酶产量、稳定性和可重复使用性。两个主要工业限制仍然突出:高甲酯化果胶降解不完全以及酶在苛刻操作条件(包括高温、极端pH、溶剂暴露)下稳定性有限。本综述进一步强调,有效解决方案越来越依赖多学科整合,包括酶组合设计、实现级联反应的双功能或共表达系统、定向进化等序列和结构引导工程方法、先进固定化策略以及可持续低成本发酵底物。这些进展使果胶酶成为食品、纤维和健康相关产业中更绿色、更高效过程的生物催化剂。
