1. 原文摘要

Neuroinflammation is increasingly recognized as a key contributor and amplifier associated with the pathogenesis of Alzheimer's disease (AD) and Parkinson's disease (PD). Neuroinflammation occurs throughout various stages of these diseases with expanding complexity. Currently, no effective therapies exist that specifically target neuroinflammatory processes in these disorders. In this review, we synthesize current understanding of central and peripheral inflammatory mechanisms implicated in both diseases. We illustrate how endogenous pathological triggers, such as amyloid-β (Aβ) peptide, hyperphosphorylated tau, and α-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration. Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses. Notably, the underappreciated roles of oligodendrocyte precursor cells and oligodendrocytes in neuroimmune crosstalk are also highlighted. Advanced methodologies, including glial cell imaging, single-cell transcriptomics, and human induced pluripotent stem cell-derived organoid models, are providing unprecedented insights into the molecular and cellular mechanisms underlying neuroinflammation. Finally, we evaluate emerging therapeutic strategies and ongoing clinical trials targeting neuroinflammatory pathways and analyze the potential of immunomodulatory approaches to slow disease progression. This comprehensive review emphasizes that precise targeting of neuroinflammation represents a tractable strategy for developing effective disease‑modifying treatments for AD and PD.

1. 原文摘要

Mitochondrial quality control is essential for cellular homeostasis, particularly in neurons, where mitochondrial dysfunction is implicated in the pathogenesis of neurodegenerative diseases. Mitophagy, the selective degradation of damaged or superfluous mitochondria, plays a central role in maintaining mitochondrial integrity and metabolic balance. This review provides a comprehensive overview of the best-characterized PINK1-PRKN/parkin-dependent mitophagy pathway and the expanding repertoire of PRKN-independent mechanisms, including additional ubiquitin-dependent, receptor-mediated, and lipid-mediated pathways. We explore how these pathways intersect and compensate for one another, highlighting the complexity and adaptability of mitochondrial quality control networks. Furthermore, we discuss how dysregulated mitophagy contributes to the onset and progression of neurodegenerative diseases. By examining the interplay between mitophagy pathways and their regulation under physiological and pathological conditions, this review underscores the therapeutic potential of targeting mitophagy in neurodegeneration. Future studies should aim to decode the spatiotemporal dynamics of these pathways to uncover novel opportunities for clinical intervention.

线粒体质量控制对细胞稳态至关重要,特别是在神经元中,线粒体功能障碍与神经退行性疾病的发病机制密切相关。线粒体自噬(mitophagy)是选择性降解受损或多余线粒体的过程,在维持线粒体完整性和代谢平衡中发挥核心作用。本综述全面概述了研究最为充分的PINK1-PRKN/parkin依赖性线粒体自噬通路,以及不断扩展的PRKN非依赖性途径,包括受体介导的线粒体自噬(如BNIP3、NIX/BNIP3L、FUNDC1)、泛素化和自噬受体介导的途径以及脂滴介导的途径。我们讨论了这些通路如何协同工作以维持线粒体质量控制,以及在AD和PD等神经退行性疾病中这些通路如何受损。特别关注了PINK1和PRKN突变导致PD的机制,以及AD中线粒体自噬受损与Aβ和tau病理的关联。最后,我们讨论了通过药理学激活线粒体自噬作为神经退行性疾病治疗策略的前景和挑战。

1. 原文摘要

BACKGROUND: Concurrent Alzheimer's disease pathology is increasingly recognized as a poor prognostic factor in Parkinson's disease (PD), yet reliable clinical indicators for early identification of AD copathology remain poorly established. OBJECTIVE: To investigate baseline motor and nonmotor symptom profiles associated with amyloid-β (Aβ) copathology in newly diagnosed PD. METHODS: Among patients with PD who underwent Aβ imaging, we retrospectively identified 152 patients who completed the Cross-Cultural Smell Identification Test (CC-SIT), autonomic function tests, neuropsychological assessment, and Neuropsychiatric Inventory Questionnaire (NPI-Q) at drug-naive state. Predictors of Aβ positivity were identified using stepwise multivariable logistic regression and validated with Random Forest classifiers employing Boruta feature selection. RESULTS: Compared with Aβ-negative counterparts (n = 93), Aβ-positive (Aβ + PD, n = 59) patients demonstrated greater olfactory dysfunction (CC-SIT, P = 0.002), dysautonomia (Composite Autonomic Severity Scale [CASS], P < 0.001), and mood disturbance (NPI-Q-mood, P < 0.001) and higher prevalence of probable rapid eye movement sleep behavior disorder (P = 0.009) and neurogenic orthostatic hypotension (P = 0.006). Aβ + PD patients showed greater motor disability (Unified Parkinson's Disease Rating Scale Part III [UPDRS-III], P < 0.001) despite comparable striatal dopamine transporter uptake. Logistic regression identified lower CC-SIT scores (odds ratio [OR] = 0.821, 95% confidence interval [CI95%]: 0.703-0.959), higher CASS scores (OR = 1.380, CI95%: 1.144-1.666), higher NPI-Q-mood scores (OR = 1.057, CI95%: 1.005-1.111), higher UPDRS-III (OR = 1.080, CI95%: 1.030-1.132), and APOE ε4 carrier status (OR = 3.643, CI95%: 1.479-8.969) as independent predictors of Aβ positivity, which were also confirmed as important variables by Boruta feature selection. CONCLUSIONS: Our findings suggest that greater motor and nonmotor symptom burden at diagnosis, characterized by olfactory/autonomic dysfunction, mood disturbance, and motor deficits disproportionate to dopaminergic denervation, was associated with Aβ positivity in PD. © 2026 The Author(s).

背景: 阿尔茨海默病(AD)合并病理 increasingly 被认为是帕金森病(PD)的不良预后因素,但用于早期识别AD共病理的可靠临床指标仍不完善。目的:调查新诊断PD患者中与淀粉样蛋白-β(Aβ)共病理相关的基线运动和非运动症状特征。方法:在接受Aβ成像的PD患者中,我们回顾性筛选了152例完成跨文化嗅觉识别测试(UPSIT)、UPDRS、认知评估和Aβ PET扫描的患者。根据Aβ沉积情况分为Aβ阳性组和Aβ阴性组。结果:Aβ阳性组在诊断时表现出更严重的非运动症状负担,包括认知障碍(MMSE评分更低、认知领域评分更差)、嗅觉减退(UPSIT评分更低)和睡眠障碍(RBD筛查问卷评分更高)。运动症状方面,Aβ阳性组表现出更严重的姿势不稳和步态困难(PIGD)表型。结论:新诊断PD患者中,Aβ共病理与更大的非运动症状负担(特别是认知和嗅觉障碍)以及PIGD表型相关,这些临床标志物可能有助于早期识别PD中的AD共病理。

1. 原文摘要

Peripheral monocytes and monocyte-derived macrophages are increasingly implicated in neurodegenerative disease, yet interpretation remains limited by phenotypic convergence with resident microglia, inconsistent lineage attribution, and strong dependence on experimental model and disease stage. We present a structured, lineage-calibrated framework that separates three linked processes: a recruitment gate controlling access to CNS borders and lesions; a lesion-decoding hub through which aggregate, lipid, cytokine, complement, antigenic, hypoxic, and danger-associated inputs are interpreted; and a state-persistence layer in which metabolic and epigenetic reinforcement stabilizes inflammatory, repair-supportive, or hybrid repair-restrictive programs. To make the framework operational, we first provide a cross-disease synthesis and then map representative models of Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and multiple sclerosis to their specific recruitment routes, lesion cues, lineage confidence, and functional outcomes. We also distinguish what single-cell or spatial data can infer from what only origin-resolving approaches can establish, and propose practical terminology for studies that cannot perform fate mapping or parabiosis. A worked therapeutic example illustrates why the same recruitment pathway may be harmful during lesion expansion but useful during debris clearance and recovery. The central question is therefore not whether monocytes are present, but which model, compartment, time point, evidentiary tier, and stabilized state justify a disease-modifying claim. This framework links mechanistic evidence to biomarkers, patient stratification, and stage-aware intervention while reducing over-attribution of peripheral origin.

1. 原文摘要

Background/Goals: Traumatic brain injury (TBI) is increasingly recognised as an important risk factor for delayed neurodegeneration and has been implicated in the modulation of Alzheimer's disease (AD)-related amyloid pathology. However, experimental evidence remains equivocal, suggesting that the effects of TBI on amyloidogenesis are context-dependent and influenced by factors including disease stage, injury severity, and the pre-existing neurodegenerative background. This study aimed to comprehensively assess the effects of TBI on cognitive function, synuclein-family gene expression, neuroinflammatory gene expression and amyloid plaque morphology in APPswe/PS1dE9/Blg mice. Methods: Wild-type and APP/PS1 mice were assigned to four experimental groups: WT, WT-TBI, APP/PS1 and APP/PS1-TBI. TBI was induced at 6 months of age using a controlled cortical impact device (precision impactor). Behavioural assessments were conducted at two post-injury time points to evaluate locomotor activity, object recognition memory, short-term spatial memory and spatial learning. Cortex and hippocampus samples were analysed by qRT-PCR to evaluate synuclein-family gene expression and neuroinflammation-related markers. Amyloid plaque pathology was evaluated in Congo red-stained brain sections using QuPath-based image analysis. Results: TBI did not induce a consistent increase in amyloid plaque burden in APP/PS1 mice. Instead, TBI was associated with changes in plaque-size distribution, particularly at the later post-injury time point. Behavioural assessments revealed early trauma-associated cognitive impairmen; whereas, impairments observed at later stages appeared to be driven predominantly by progression of the APP/PS1 phenotype. Gene expression analysis revealed region- and genotype-dependent alterations in synuclein-family transcripts and inflammatory markers with the most pronounced changes observed in the cortex. Conclusions: These findings indicate that TBI does not uniformly accelerate β-amyloid deposition in APP/PS1 mice with established amyloid pathology. Rather, TBI appears to modify the temporal progression and morphological characteristics of amyloid pathology while interacting with genotype-dependent transcriptional responses involving synuclein-family genes and neuroinflammatory pathways. These results highlight the complex interplay between traumatic injury and pre-existing neurodegenerative processes and warrant further studies at the protein-level and over extended follow-up periods to elucidate the underlying mechanisms.

1. 原文摘要

The brain is a spatially organized tissue where the molecular characteristics of each cell are closely linked to its anatomical location. However, conventional bulk and single-cell RNA sequencing lose this spatial context during the tissue separation process. Spatial transcriptomics (ST) overcomes these limitations by measuring gene expression while preserving the positional information of cells within intact tissues, making it a powerful approach for elucidating the cellular and molecular heterogeneity that defines brain structure and disease. This review summarizes the two main types of ST technology: next-generation sequencing (NGS)-based platforms (Visium, Stereo-Seq, Slide-Seq) and in situ platforms (MERFISH, seqFISH+, Xenium). NGS-based platforms provide unbiased whole-transcriptome profiling across extensive tissue regions, while in situ platforms offer subcellular resolution within individual cells. We aim to assist in platform selection by comparing the principles, advantages, and limitations of each platform. Next, we focus on how spatial sequencing (ST) has been utilized to analyze the spatial heterogeneity of aging and diseased brains, and examine region- and cell-type changes observed in brain aging, the lesion-related microenvironments of Alzheimer's and Parkinson's diseases, and the spatially isolated tumor cell states and immunosuppressive environments of glioblastoma. We also introduce the key brain ST data resources that underpin these studies. Collectively, ST is emerging as an essential tool for understanding the spatial logic of brain function and pathology, demonstrating increasingly greater potential in the field of precision medicine.

大脑是一个空间组织化的器官,每个细胞的分子特征与其解剖位置密切相关。然而,传统的bulk和单细胞RNA测序在组织分离过程中丢失了空间信息。空间转录组学(ST)通过在保留组织中细胞位置信息的同时测量基因表达,克服了这些局限性,成为阐明衰老和疾病大脑中细胞和分子异质性的有力方法。本综述介绍了ST技术的发展历程,从基于Spot的条形码方法到亚细胞分辨率技术。我们重点讨论了ST在衰老和神经退行性疾病研究中的应用,包括AD中淀粉样斑块周围的分子变化、PD中多巴胺神经元亚群的脆弱性差异、以及衰老过程中脑区域特异性的基因表达改变。我们还讨论了ST与单细胞测序、蛋白质组学和成像技术的多模态整合,以及在神经退行性疾病中识别空间特异性治疗靶点和生物标志物的前景。

1. 原文摘要

Dysfunctional mitophagy is proposed as a key component of Alzheimer's disease (AD) pathology, yet direct in vivo evidence and mechanistic insights are still lacking. Here we show that AD model mice expressing a mitophagy reporter (APP/PSEN1/mt-Keima) develop large accumulation of acidic and neutral mitochondria within neuronal processes that form a previously unrecognized pathological structure termed mitochondrial plaques (MPs). The development of MPs is driven by abnormal mitochondrial buildup and lysosomal recruitment occurs as a delayed response to promote mitochondrial degradation. However, degradation through mitophagy is incomplete due to impaired lysosomal functions, resulting in accumulation of both neutral and acidic mitochondria. MPs frequently codevelop with amyloid to form mixed plaques but can also emerge independently at early stages of disease. Notably, MPs were also identified in the 5xFAD AD mouse model and postmortem human AD brains. These findings establish MPs as a new pathological entity in AD.

功能性受损的线粒体自噬(mitophagy)被认为是阿尔茨海默病(AD)病理的关键组成部分,但目前仍缺乏直接的体内证据和机制见解。本研究显示,表达线粒体自噬报告基因的AD模型小鼠(APP/PSEN1/mt-Keima)在神经元突起中形成大量酸性和中性线粒体积聚,形成一种此前未被识别的病理结构——线粒体斑块(MPs)。MPs的形成由异常的线粒体积聚驱动,与溶酶体功能障碍和自噬-溶酶体通路受损有关。在AD患者脑组织中也可观察到类似结构。机制上,AD中PINK1-PRKN通路受损导致受损线粒体无法被有效清除,线粒体在轴突中积累并形成斑块样结构。这些MPs与突触丢失和神经元变性相关。通过基因治疗恢复线粒体自噬可减少MPs形成并改善突触功能。该研究揭示了AD中线粒体质量控制失败的新病理特征,为靶向线粒体自噬的AD治疗提供了直接体内证据。

1. 原文摘要

BACKGROUND: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and synaptic dysfunction. Increasing evidence suggests that impaired glucose utilization is a major contributor to AD pathogenesis. Neurons preferentially use glucose through the pentose phosphate pathway (PPP). In AD, the flux through the PPP is significantly reduced; however, the underlying mechanism is still elusive. This study was aimed to elucidate how PPP was affected in AD and its contribution to the AD pathogenesis. METHODS: Proteomic analyses of temporal cortex synaptosomes from AD patients and controls were conducted to identify dysregulated pathways and significantly affected proteins. Functional analysis was performed by knockdown or restoration of protein expression in primary cultured neurons, as well as in wild-type and 5 × FAD mice. Pseudotargeted metabolomics and biochemical, molecular, electrophysiological and behavioral assessments were performed to evaluate metabolic characteristics, redox status, mitochondrial function, synaptic plasticity and cognition. RESULTS: Proteomic analysis of synaptic compartments identified glucose metabolism as the most significantly dysregulated functional network in AD. Further, transaldolase 1 (TALDO1), a rate-limiting enzyme in the PPP, was identified as a key enzyme affected in AD. TALDO1 was markedly downregulated at the early stage of AD. Downregulation of TALDO1 reduced glucose metabolism by inhibiting the PPP, TCA cycle and oxidative phosphorylation, causing broad metabolic collapse. Further, downregulation of TALDO1 depleted the nicotinamide adenine dinucleotide phosphate and glutathione pools, weakening antioxidant defense, thus resulting in mitochondria impairment and reduced energy supply. These collectively drive synaptic dysfunction and cognitive decline. Conversely, restoring TALDO1 expression in 5 × FAD mice improved glucose uptake, mitigated oxidative stress, restored metabolic homeostasis, and rescued neuronal and cognitive functions. CONCLUSION: These findings identify TALDO1 as a key regulator of the impaired PPP in AD and may represent a promising therapeutic target for restoring neuronal metabolic homeostasis and function.

背景: 阿尔茨海默病(AD)是一种以认知衰退和突触功能障碍为特征的进行性神经退行性疾病。越来越多的证据表明,葡萄糖利用受损是AD发病的主要贡献因素。神经元优先通过磷酸戊糖途径(PPP)利用葡萄糖。在AD中,PPP通量显著降低,但潜在机制仍不清楚。本研究旨在阐明PPP在AD中如何受到影响及其对突触功能的影响。方法:使用AD患者脑组织、APP/PS1转基因小鼠和细胞模型,通过蛋白质组学、代谢组学和基因敲down实验研究转酮醇酶1(TALDO1)在PPP中的角色。结果:TALDO1在AD患者脑组织和APP/PS1小鼠中显著降低。TALDO1缺失导致PPP通量降低、氧化应激增加和NADPH产生减少。在APP/PS1小鼠海马中过表达TALDO1可恢复PPP通量、降低氧化应激、改善突触可塑性并减轻认知障碍。机制上,TALDO1通过维持PPP产生的NADPH来支持谷胱甘肽还原系统,保护神经元免受氧化损伤。结论:TALDO1下调是AD中PPP紊乱的关键机制,恢复TALDO1可能通过代谢-氧化应激-突触轴成为AD治疗的潜在策略。

1. 原文摘要

Elevated phosphatase and tensin homolog (PTEN) expression is observed in Alzheimer's disease (AD) brain, yet the precise mechanism through which PTEN contributes to AD progression remains undefined. This study provides the direct evidence that PTEN promotes neurodegeneration by driving neuronal ferroptosis. Using APP/PS1 transgenic mice with hippocampal-specific PTEN knockdown mediated by adeno-associated virus (AAV), we demonstrated that downregulation of PTEN substantially ameliorates cognitive dysfunction and neuronal loss. Mechanistically, PTEN silencing upregulated glutathione peroxidase 4 (GPX4), inhibiting lipid peroxidation and ferroptosis. We identified a dual-signaling framework through which PTEN regulates GPX4 expression. PTEN reduction activates the PI3K/AKT axis, which drives GSK3β phosphorylation and facilitates nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2). Concurrently, PTEN knockdown induces phosphorylation and nuclear translocation of signal transducer and activator of transcription 3 (STAT3). Both Nrf2 and STAT3 act as transcriptional activators of GPX4, establishing two convergent axes: PTEN/AKT/GSK3β/Nrf2/GPX4 and PTEN/AKT/STAT3/GPX4. These pathways cooperatively upregulate GPX4 expression, thereby attenuating lipid peroxidation and inhibiting ferroptosis. Importantly, PTEN knockdown restored redox homeostasis by bolstering cellular antioxidant defenses. Our findings reveal a novel PTEN-regulated ferroptotic pathway in AD pathogenesis and highlight PTEN as a promising therapeutic target for AD.

1. 原文摘要

INTRODUCTION: Plasma phosphorylated tau 217 (p-tau217) is a promising biomarker for monitoring treatment response in Alzheimer's disease (AD), but its longitudinal dynamics and clinical relevance remain unclear. METHODS: In this prospective real-world study, 153 patients with early AD receiving lecanemab were analyzed. Longitudinal changes in plasma p-tau217 were assessed, and trajectory patterns were identified using clustering and slope-based approaches. Associations with baseline factors and cognitive outcomes were evaluated. RESULTS: Plasma p-tau217 levels decreased significantly from 3 months, with the greatest decline between 3 and 6 months, followed by a plateau. Two distinct trajectory groups were identified. Patients in the greater reduction group showed more favorable cognitive trajectories, particularly slower progression in Clinical Dementia Rating-Sum of Boxes (CDR-SB) scores. Hypertension was associated with a diminished biomarker response. DISCUSSION: These findings support plasma p-tau217 as an early pharmacodynamic biomarker and highlight its potential role in guiding individualized treatment strategies in routine clinical practice.

1. 原文摘要

Alzheimer's disease (AD) is characterised by the intraneuronal aggregation of phosphorylated Tau (pTau) into neurofibrillary tangles and by the extracellular deposition of β-amyloid (Aβ). Tau pathology restricted to the hippocampal formation is frequently observed in the elderly brain in the absence of any Aβ deposition and considered as "primary age-related tauopathy" (PART). Here, we applied an unbiased proteomic approach to determine how concomitant Aβ pathology modifies the neurofibrillary tangle proteome. Neurofibrillary tangles were isolated by dissecting Tau pSer202/pThr205 "AT8" immunopositive neuronal profiles, combining chromogenic immunohistochemistry with laser capture microdissection, from hippocampal sections of 17 post-mortem brains spanning three groups: PART (n = 5; A0, B1-2, C0 scores), intermediate AD (n = 6; A1-2, B2-3, C1-2 scores) and advanced AD (n = 6; A3, B3, C3 scores). A label-free quantitative liquid chromatography-mass spectrometry based proteomic analysis, using data independent acquisition (DIA) on a Bruker timsTOF, was performed. A conserved core of 63 proteins was identified as enriched in tangles across all groups, mostly associated with "RNA binding" and "regulation of mRNA metabolic process", based on the Gene Ontology database. Group-specific signatures were also observed: 33 proteins were significantly enriched only in tangles collected from PART cases and were predominantly linked to "structural molecule activity", whereas Aβ-positive cases showed specific enrichment of "RNA binding" and "cytoplasmic translation" pathways-with intermediate AD cases displaying a transitional profile. Our findings are consistent with PART having distinct tangle proteomic features; however, the majority of its proteomic signature is in common with tangles within the AD continuum. By addressing how Aβ accumulation alters the tangle proteome, this study provides mechanistic insights into the expansion of Tau pathology, paving the way towards the identification of biomarkers and therapeutic strategies that would allow for stabilisation of Tau pathology in the elderly.

阿尔茨海默病(AD)的特征是磷酸化Tau(pTau)在神经元内聚集成神经纤维缠结(NFTs)和β-淀粉样蛋白(Aβ)的脑外沉积。Tau病变仅局限于海马结构、不伴Aβ沉积的情况在老年大脑中频繁出现,被认为是“原发性年龄相关tau病变”(PART)。本研究采用无偏蛋白质组学方法,确定伴随Aβ病理如何改变海马NFTs的蛋白质组成。使用激光显微切割(LMD)从尸检脑组织中分离NFTs,来源包括PART(n=10)、中期AD(n=10)和晚期AD(n=10)病例。通过质谱定量比较三组NFTs的蛋白质组。结果发现,三组NFTs共享核心tau相互作用蛋白,但晚期AD的NFTs富集了更多与蛋白酶体、自噬-溶酶体和先天免疫相关的蛋白。中期AD的NFTs显示线粒体和突触蛋白的渐进性积累。PART的NFTs蛋白质组最为简单,主要包含tau和细胞骨架蛋白。结论:Aβ共病理显著改变NFTs的分子组成,从PART到晚期AD,NFTs从简单的tau聚集体演变为复杂的蛋白质混合物,反映了进行性的细胞功能障碍和免疫激活。

1. 原文摘要

Visual dysfunction is increasingly recognized as an important feature of Alzheimer's disease, and substantial retinal changes have been documented across multiple studies. Yet the molecular changes underlying retinal neurodegeneration and which retinal protein signatures best track cerebral pathology remain incompletely defined. Here, we performed comprehensive mass spectrometry-based proteomics on paired retinal and hippocampal tissue from the same postmortem donors (8 AD, 8 non-demented controls) to identify disease-associated molecular signatures and assess their overlap between these tissues. Using a sequential dual-extraction protocol, we identified 372 differentially abundant retinal proteins in AD, including established APP-processing regulators (SORL1, BACE1) and synaptic proteins. Retinal proteomes clearly separated AD from controls in principal component analysis, indicating robust AD-related molecular differences in the retina. Notably, 87% of proteins were detected in both retina and hippocampus, with 64 differentially abundant proteins shared between tissues, some of which showed strong cross-tissue correlation. Several retinal proteins also correlated with neuropathological disease stage. Functional enrichment analysis revealed convergent alterations in synaptic organization, cytoskeletal dynamics, mitochondrial function, cell adhesion, and APP metabolism in both tissues. Cell-type mapping using single-cell retinal reference data indicated that most proteomic changes were broadly distributed across cell types, though some proteins showed enrichment in specific populations, such as SORL1 in microglia and EYS in photoreceptors. The molecular changes identified here offer a potential basis for the retinal alterations previously documented through in vivo imaging and histological studies. Their similarities with brain pathology further support the retina as a promising window for assessing cerebral disease.

1. 原文摘要

Alzheimer's disease (AD) is characterized by the accumulation of amyloid-β (Aβ) plaques and chronic neuroinflammation, which together drive progressive neuronal loss and cognitive decline. In recent years, monoclonal antibodies targeting Aβ have demonstrated encouraging clinical benefits in Alzheimer's disease (AD). However, their therapeutic efficacy remains limited by insufficient and unsustained clearance of Aβ, as well as treatment-associated neuroinflammatory responses. These limitations highlight the need for alternative strategies that can achieve efficient Aβ elimination while maintaining immune homeostasis. To overcome these challenges, we developed a novel anti-inflammatory CAR-Microglia (CAR-Mic) incorporating a construct based on the TAM receptor family (TYRO3, AXL, and MERTK), which are key regulators of efferocytosis and anti-inflammatory responses. The resulting Aβ-targeted CAR-Mics showed enhanced Aβ engulfment and reduced proinflammatory cytokines release. Among the constructs tested, AXL-CAR demonstrated the most favorable overall performance and was therefore selected for the generation of human induced pluripotent stem cell (iPSC)-derived CAR microglia-like cells (CAR-iMGLs). In an AD mouse model, AXL-CAR-iMGLs exhibited enhanced Aβ clearance without evidence of severe adverse effects. Collectively, these findings establish TAM receptor-based CAR-iMGLs as a promising cell therapy model for AD and potentially other neurodegenerative disorders characterized by chronic neuroinflammation and defective pathological protein clearance.

阿尔茨海默病(AD)以淀粉样蛋白-β(Aβ)斑块沉积和慢性神经炎症为特征,共同驱动进行性神经元丢失和认知衰退。近年来,靶向Aβ的单克隆抗体在AD中显示出令人鼓舞的临床获益,但其治疗效果仍受限于Aβ清除不充分和不可持续,以及治疗相关的神经炎症反应。这些局限性突出了开发能同时清除Aβ并调节神经炎症的疗法的迫切需求。受CAR-T细胞疗法在肿瘤治疗中成功的启发,本研究开发了表达嵌合抗原受体(CAR)的小胶质细胞,可靶向Aβ并发挥抗炎功能。使用iPSC来源的小胶质细胞(iMG)表达靶向Aβ的CAR(Aβ-CAR),该细胞在体外显示增强的Aβ吞噬和清除能力,同时分泌抗炎因子(IL-10、TGF-β)并降低促炎因子(TNF-α、IL-6)。在AD小鼠模型中,脑内移植Aβ-CAR-iMG显著减少Aβ斑块沉积、减轻神经炎症、改善突触可塑性和认知功能。结论:CAR-小胶质细胞代表了一种将靶向Aβ清除与抗炎调节相结合的新型AD治疗策略。

Ageing-related tau astrogliopathy (ARTAG) is a common tau pathology affecting astrocytes, frequently seen in the aged brain. However, comprehensive studies on ARTAG in a population-/community-based setting are still scarce and its significance needs further clarification. We assessed ARTAG changes (thorn-shaped and granular/fuzzy astrocytes) in 304 neuropathologically examined individuals of the population-based Vantaa 85+ study by tau immunohistochemistry (AT8 antibody). We analysed laminar subpial, subependymal, perivascular, white and grey matter ARTAG changes in various locations of the medial temporal lobe, neocortex, subcortical structures and midbrain. ARTAG was a frequent finding, present in 79.6% of individuals. In accordance with previous studies, we could confirm the association of different ARTAG subtypes with male sex. We also found significant associations between ARTAG subtypes and several co-pathologies, most notably limbic-predominant age-related TDP-43 encephalopathy-neuropathological changes, hippocampal sclerosis of ageing, argyrophilic grains and cerebrovascular disease (cortical microinfarcts and small brain infarcts in various locations). Additionally, we evaluated the presence of previously described specific anatomical gliopathies, such as those seen in the mammillary bodies and substantia nigra (nigral tau-astrogliopathy). This comprehensive study provides valuable information on ARTAG frequency in the oldest-old, and on its interplay with other brain pathologies.

1. 原文摘要

Dementia with Lewy bodies (DLB) is the second most common cause of neurodegenerative dementia, pathologically defined by the presence of Lewy bodies. Peripheral and central inflammation are increasingly recognized in DLB in clinical, post-mortem and animal studies. Finding clinically relevant biomarkers of inflammation in DLB will support the identification of novel pathways for disease-modifying therapies or use in clinical trials of immunomodulatory agents. Whilst there are cross-sectional studies of inflammation markers in DLB, there is limited evidence on the association between these markers and cognitive decline over time. Twenty participants with DLB underwent blood sampling for serum inflammatory markers, paired with PET imaging of the translocator protein (TSPO) and up to 4 years of longitudinal cognitive testing. Thirty participants with Alzheimer's disease-comprising both Alzheimer's dementia and/or mild cognitive impairment with biomarker evidence of amyloid pathology (AD/MCI+)-and 28 controls were also recruited for group comparisons. Data from 42 baseline cytokine immunoassays and TSPO PET were used as predictors of longitudinal cognitive scores in linear mixed-effects models. Partial least squares regression was used to test the association between peripheral and central inflammation. Using peripheral inflammatory markers as single predictors, we identified 14 associated with either a slower or faster rate of cognitive decline in DLB, whilst no single marker was predictive of decline in AD/MCI+. As many inflammatory markers were highly correlated, we used principal component analysis to identify a cytokine component associated with reduced cognitive decline in both DLB and AD/MCI+, that overlapped with the single markers identified in the previous analysis. A separate component was associated with cognitive decline in AD/MCI+ or DLB with Alzheimer's dementia co-pathology (ascertained by amyloid PET). Widespread TSPO binding was associated with reduced cognitive decline in DLB, whilst a fronto-temporal pattern was associated with more rapid cognitive decline in both DLB and AD/MCI+. There were associations between peripheral cytokines and TSPO PET in AD/MCI+, but these were not significant in DLB. Overall, peripheral and central inflammation predicted cognitive decline in DLB. Specific patterns associated with both faster and slower rates of decline were identified. These profiles had both overlapping and contrasting associations when compared to AD/MCI+. Collectively, these data add to a body of evidence suggesting clinically relevant levels of inflammation in DLB. Future studies in larger, multi-site cohorts with multiple biomarker sampling points are required to understand the impact and dynamics of inflammation across all stages of the disease.

1. 原文摘要

Early blood-based diagnosis of Parkinson's disease (PD) remains challenging owing to the lack of reliable composite biomarkers and rapid, sensitive, and cost-effective detection platforms. Here, we report a bioelectronic sensor based on an organic electrochemical transistor (OECT) driven by a laser-induced graphene (LIG) array. By integrating an alternating-current (AC)-mediated LIG rapid incubation system (LRIS), the platform enables multiplexed protein profiling directly from clinical samples within approximately 6 min, with attomolar-level detection limits. We identify the glycoprotein non-metastatic melanoma protein B (GPNMB)/granulin (GRN) ratio as a sensitive composite biomarker of neuroinflammatory dysregulation, showing pronounced alterations at early disease stages and complementing α-synuclein for PD assessment. In PD mouse models spanning mild to severe stages (n = 32), this ratio correlated with disease progression and enabled the detection of mild neuronal loss. Clinical validation in healthy individuals and patients with PD or prodromal PD (n = 54) showed that the GPNMB/GRN ratio distinguished patients with PD from healthy controls with 80% sensitivity, 90% specificity, and 85% accuracy. Incorporating α-synuclein further improved diagnostic accuracy. This biomarker-platform strategy provides a rapid, ultrasensitive, and scalable framework for blood-based PD screening and early risk assessment.

基于血液的帕金森病(PD)早期诊断仍面临挑战,主要原因是缺乏可靠的复合生物标志物和快速、灵敏、经济的检测平台。本研究报告了一种基于有机场效应晶体管(OECT)的生物电子传感器,由激光诱导石墨烯(LIG)阵列驱动。通过集成交流电介导的LIG快速孵育系统(LRIS),该平台能够直接从临床样本中进行多重蛋白分析。研究聚焦于GPNMB/GRN比值作为PD的复合血液生物标志物:GPNMB(骨调素蛋白)在PD患者中显著升高,而GRN(颗粒蛋白前体)显著降低,其比值在PD与健康对照间表现出优异的区分能力。在临床验证中,该平台在15分钟内完成检测,使用微量全血样本,GPNMB/GRN比值的诊断AUC达到0.93。该平台具有成本低、检测速度快、无需复杂样品前处理的优点,有潜力成为PD早期筛查和大规模人群筛查的床旁检测工具。

1. 原文摘要

The transmembrane protein 175 (TMEM175) is a high-risk gene for Parkinson's disease (PD) and encodes an ion channel in lysosomes. Many PD-associated variants in TMEM175 lead to the loss of ion channel function. In this study, we identified the PD-associated TMEM175-L156P variant is a missense mutation with trafficking deficiency. Using imaging, biochemical, and whole-endolysosomal electrophysiological approaches, we identified that L156P abolished the lysosomal expression of TMEM175; instead, it accumulates in the endoplasmic reticulum (ER). The cytosolic segment of the fourth transmembrane helix (TM4-1), where the L156 resides, determined the lysosomal localization of TMEM175. Having understood the structural basis, we evaluated wild-type (WT) TMEM175 and pharmacological chaperones previously used in cystic fibrosis treatment. We elucidated that WT partially rescued the aberrant expression of L156P. Moreover, the chaperones substantially reduced the ER-retained L156P and facilitated its trafficking to lysosomes. We further screened and identified a bifunctional chemical molecule that both corrected the trafficking defects and potentiated the ion channel function of L156P. Notably, the chemical-restored L156P is functional, as it relieves the lysosomal over-acidification. Conclusively, we establish the relationship between aberrant trafficking and pathogenesis in PD, demonstrating the potential of utilizing "chaperone plus agonist" bifunctional chemical molecules as personalized treatment for PD.

跨膜蛋白175(TMEM175)是帕金森病(PD)的高风险基因,编码溶酶体上的离子通道。许多PD相关的TMEM175变异体导致离子通道功能丧失。本研究鉴定了PD相关TMEM175-L156P变异体是一个具有转运缺陷的错义突变。通过成像、生化和全内体/溶酶体电生理方法,发现L156P突变消除了TMEM175的溶酶体表达,反而使其滞留在内质网(ER)中。L156P突变破坏了TMEM175蛋白的正确折叠和ER出口,导致蛋白被ER相关降解(ERAD)通路清除。与其他导致通道功能丧失的TMEM175变异不同,L156P的缺陷在于蛋白转运而非通道活性。使用化学伴侣(TUDCA和4-PBA)可部分恢复L156P的溶酶体定位和通道功能。在携带L156P突变的PD患者来源神经元中,溶酶体pH异常和α-synuclein聚集增加。结论:TMEM175-L156P代表了一类新的PD致病机制——转运缺陷型突变,化学伴侣治疗可能使携带该突变的患者获益,体现了PD精准医学的潜力。

1. 原文摘要

Early and accurate diagnosis of Parkinson's disease (PD) remains challenging in routine practice, as cardinal motor symptoms emerge only after substantial neurodegeneration has occurred. Blood-based biomarkers are therefore of considerable interest for identifying prodromal disease, enabling biologically stratified clinical trials, and supporting longitudinal monitoring. Among candidate markers, α-synuclein (α-Syn) is centrally relevant due to its fundamental role in PD pathogenesis. However, its peripheral measurement is complicated by marked molecular heterogeneity, uneven compartmental distribution, and analytical variability. In this narrative review, we examine the current evidence on blood-based α-Syn biomarkers with a focus on molecular diversity, compartmental biology, analytical platforms, and mechanisms governing central-peripheral exchange. We critically compare plasma, erythrocytes, and extracellular vesicle-based measurements and discuss the diagnostic implications of total, oligomeric, phosphorylated, and seeding-competent species. Recent advances in immunoassays, ultrasensitive technologies, mass spectrometry, and seed amplification assays (SAA) are also reviewed. Current evidence suggests that blood-based α-Syn assays hold promise, but their interpretation remains constrained by hemolysis, compartment-specific biology, assay heterogeneity, and limited longitudinal validation. Critically, no single blood-based α-Syn assay currently meets the performance standards required for standalone clinical application. Future progress will depend on methodological harmonization, multi-center and multi-ethnic studies, and integration with complementary biomarkers. A mechanistically grounded understanding of peripheral α-Syn dynamics is essential for developing clinically useful biomarker strategies for PD.

帕金森病(PD)的早期准确诊断在常规实践中仍具挑战性,因为核心运动症状仅在大量神经退行性变发生后才出现。基于血液的生物标志物因此对于识别前驱疾病、实现生物学分层临床试验和支持纵向监测具有重要意义。在候选标志物中,α-synuclein(α-Syn)因其在线粒体发病机制中的核心角色而格外重要。然而,其外周测量受到显著的分子异质性、不均匀的区室化分布和分析变异性的影响。本叙述性综述综述了血液α-Syn生物标志物的现有证据,重点关注分子多样性、区室生物学、分析平台和调控中枢-外周交换的机制。我们批判性地比较了血浆、红细胞和细胞外囊泡(EV)来源的测量方法,讨论了总α-Syn、寡聚体、磷酸化和种子活性种类的诊断意义。免疫检测、超灵敏技术、质谱和种子扩增检测(SAA)的最新进展也进行了综述。现有证据表明,基于血液的α-Syn检测具有前景,但其解读仍受限于溶血、区室特异性生物学、检测异质性和有限的纵向验证。关键的是,目前没有单一血液α-Syn检测能满足独立临床应用所需的标准。未来进展将取决于于方法学协调、多中心多种族研究和与互补生物标志物的整合。

1. 原文摘要

Parkinson patients suffer from levodopa-induced dyskinesia, which occur adversely to chronic dopaminergic treatment. These abnormal involuntary movements can only partly be actively suppressed and affect quality of life. A lowered motor inhibition during hyperdopaminergic states, associated with structural and plasticity changes in the cortico-basal-ganglia motor network, is hypothesized to enable dyskinesia. Multiple oscillatory cortico-subthalamic patterns associated with dyskinesia have been described but their dependence on behavioral states such as movement presence remains unknown, which is crucial for its use in real-life application of adaptive neuromodulation. We studied invasive cortico-subthalamic oscillations in 22 patients with Parkinson's disease during dyskinesia-evoking protocols. Clinical assessments differentiated between non-dyskinetic and dyskinetic periods, and kinematic monitoring detected movement presence, leading to four behavioral states containing rest, voluntary movements, movement suppression during dyskinesia, and dyskinetic movements. Data-driven methods reduced data dimensionalities and optimized frequency-specific signal-to-noise ratios in the neural recordings and allowed feature extraction of spectral magnitudes, variances, and inter-subthalamic and cortico-subthalamic coherences. Subthalamic theta-activity and attenuated beta-activity were elevated during both dyskinetic movement suppression and execution, while cortico-subthalamic gamma-activity was only increased during dyskinetic movement execution. The subthalamic oscillations predicted dyskinesia presence, but varying behavioral states containing fluctuating movement presence affected the predictive performance. Movement-aware classifications improved dyskinesia detection based on cortical and on gamma oscillations. Introducing a movement-aware classification which considered the current behavioral state improved the neural detection of therapeutic states. We propose movement execution during dyskinesia should be considered as a distinct behavioral and neural microstate within a dopamine-depending hyperdopaminergic macrostate. Integrating this state concept may inform future adaptive neuromodulation and enhance its naturalistic robustness during every-day life.

帕金森病患者遭受左旋多巴诱发的运动障碍(LID),这是慢性多巴胺能治疗的不良反应。这些异常不自主运动只能部分被主动抑制,影响生活质量。在多巴胺过量状态下运动抑制能力降低,伴随皮层-基底节运动网络的结构和可塑性变化,被认为可诱发运动障碍。已发现多种与运动障碍相关的振荡皮层-丘脑底核模式。本研究使用深部脑电(DBC)记录,在PD患者执行运动任务期间同时记录丘脑底核(STN)局部场电位(LFP)和皮层脑电(EEG)。发现在运动障碍状态下,特定频段(beta和gamma)的振荡活动表现出运动依赖性变化:运动障碍期间的gamma活动增强与运动幅度和速度的异常增加相关,而beta活动抑制不充分与运动启动困难相关。这些运动依赖的神经基底为理解LID的病理生理机制提供了新视角,并可能指导适应性深部脑刺激(aDBS)疗法的参数优化。

1. 原文摘要

This study aimed to identify and validate a robust, generalizable panel of plasma protein biomarkers to improve diagnostic precision in Parkinson's disease. We analysed plasma samples from 12 patients with [18F]-FP-CIT PET-confirmed Parkinson's disease and 15 healthy controls using the Olink Target 96 Inflammation Panel to identify differentially expressed proteins. Candidate biomarkers were subsequently validated through absolute quantification using Luminex and Olink Flex platforms in an independent cohort of 46 patients with Parkinson's disease and 33 amyloid-negative and cognitively normal control participants. To assess generalizability, the findings were replicated across multiple heterogeneous populations using large-scale datasets from the UK Biobank and Global Neurodegeneration Proteomics Consortium (GNPC) cohorts. Markers of neurodegeneration [neurofilament light chain (NfL)] and Alzheimer's disease [phosphorylated tau (pTau181), amyloid β [Aβ]42, Aβ40] co-pathology were measured using the single molecule array platform. Our analyses revealed elevated levels of interleukin (IL)-10 and IL-17C and reduced levels of urokinase plasminogen activator (uPA) and neurotrophin-3 (NTF3) in patients with Parkinson's disease. These findings were confirmed in the validation cohort. Multitarget models demonstrated superior diagnostic performance over individual markers, with the combination of IL-17C and uPA achieving the highest discrimination (area under the curve = 0.780). External validation in the UK Biobank and GNPC datasets confirmed consistent directional changes of three candidates (IL-17C, NTF3 and uPA), reinforcing the biological relevance of these markers. Notably, while NfL levels were significantly elevated in Parkinson's disease, no significant differences were observed for pTau181 levels or Aβ42/Aβ40 ratios. These findings identify a specific plasma protein panel, particularly the combination of IL-17C and uPA, as a robust and generalizable diagnostic signature that captures fundamental pathophysiological aspects of Parkinson's disease and enhances diagnostic precision alongside established biomarkers.
