阿尔茨海默症与帕金森病文献周报_2026-07-21
阿尔茨海默病(AD)是导致痴呆的主要原因,是一种以进行性认知障碍和记忆丧失为特征的常见年龄相关神经退行性疾病。尽管小胶质细胞的代谢激活或功能障碍已被认为参与AD发病机制,但小胶质细胞内磷脂代谢相关的信号机制仍不清楚。本研究发现,犬尿氨酸通路中色氨酸分解代谢的副产物喹啉酸(QA)激活了小胶质细胞中磷脂酰乙醇胺(PE)的合成。机制上,QA通过调节关键酶CTP:磷…

1. 原文摘要
Alzheimer's disease (AD) is a major cause of dementia and a prevalent age-related neurodegenerative disorder characterized by progressive cognitive impairment and memory loss. Although metabolic activation or dysfunction of microglia is implicated in AD pathogenesis, the phospholipid metabolism-associated signaling mechanisms within microglia remain poorly defined. In this study, we demonstrate that quinolinic acid (QA), a byproduct of tryptophan catabolism via the kynurenine pathway, activates the microglial Kennedy pathway-responsible for de novo phosphatidylethanolamine (PE) biosynthesis-by upregulating the enzymes EPT1 and ETNK1. This activation markedly enhances the synthesis of PE species enriched in polyunsaturated fatty acids. Concurrently, QA significantly increases the expression of gamma-aminobutyric acid receptor-associated protein (GABARAP), promotes its lipidation, and facilitates the GABARAP-associated phagocytosis (GAP) of Aβ oligomers by microglia. Knockdown of EPT1 and ETNK1 attenuated QA-induced PE synthesis and impaired the GAP of Aβ oligomers, whereas inhibition of GABARAP lipidation via STBD1 deconjugase substantially reduced QA-mediated GAP. QA administration upregulated microglial Gabarap expression and decreased the Aβ plaque burden in the hippocampus of AD (5xFAD) mice, whereas Gabarap knockdown abrogated QA-induced microglial clearance of Aβ. Collectively, these findings reveal a paradoxically beneficial role of QA in activating a microglia-specific signaling cascade that promotes PE biosynthesis and GAP, thereby enhancing Aβ clearance and mitigating AD pathology. Targeting the microglial PE synthesis pathway and GAP may represent a promising therapeutic strategy to ameliorate Aβ accumulation and slow AD progression.

阿尔茨海默病(AD)是导致痴呆的主要原因,是一种以进行性认知障碍和记忆丧失为特征的常见年龄相关神经退行性疾病。尽管小胶质细胞的代谢激活或功能障碍已被认为参与AD发病机制,但小胶质细胞内磷脂代谢相关的信号机制仍不清楚。本研究发现,犬尿氨酸通路中色氨酸分解代谢的副产物喹啉酸(QA)激活了小胶质细胞中磷脂酰乙醇胺(PE)的合成。机制上,QA通过调节关键酶CTP:磷酸乙醇胺胞苷转移酶(Pcyt2)促进PE合成,进而增强GABARAP(GABA_A受体相关蛋白)的脂化及其与自噬/吞噬机制的关联,最终促进Aβ的吞噬和清除。小胶质细胞Pcyt2的条件性敲除显著损害Aβ清除,加剧AD小鼠模型中的淀粉样蛋白病理和认知缺陷。相反,通过药物或遗传手段增强PE合成可促进GABARAP相关吞噬作用、减少Aβ沉积并改善认知功能。这些发现揭示了小胶质细胞磷脂代谢在Aβ清除中的关键作用,并为AD提供了靶向PE合成通路的新治疗策略。
3. 摘要层面解读
研究对象:AD患者脑组织样本、5×FAD转基因AD小鼠模型、原代小胶质细胞培养。
疾病类型:AD。
核心科学问题:小胶质细胞中磷脂代谢(尤其是磷脂酰乙醇胺合成)如何调控Aβ的吞噬清除?其下游分子机制是什么?能否作为AD治疗靶点?
主要方法:脂质组学分析、单细胞RNA测序、条件性基因敲除小鼠(Pcyt2-cKO)、Aβ吞噬实验、行为学测试(Morris水迷宫、Y迷宫)、免疫组化、Co-IP、脂化分析。
主要发现:(1) AD患者和AD小鼠模型中小胶质细胞PE合成通路显著上调,由QA驱动;(2) Pcyt2是PE合成的关键限速酶;(3) PE促进GABARAP脂化,增强其与LC3和吞噬机制的关联;(4) Pcyt2敲除损害Aβ清除、加剧病理和认知缺陷;(5) 增强PE合成可改善AD表型。
对AD研究的意义:首次揭示小胶质细胞磷脂代谢在Aβ清除中的直接调控作用,开辟了"代谢-吞噬-清除"新范式,为AD治疗提供了可药物化的新靶点(Pcyt2/PE合成通路),区别于传统的Aβ抗体免疫治疗策略。
值得关注的原因:JIF=52.7的顶级期刊、原创机制研究、发现全新治疗靶点、OA可全文分析。
4. 全文精读分析
研究背景:AD中小胶质细胞功能失调已被广泛报道,但研究方向主要集中于炎症信号(如TREM2、NLRP3)和转录程序(DAM/MGnD)。小胶质细胞的代谢重编程——特别是磷脂代谢——在AD中的角色一直未被系统研究。磷脂酰乙醇胺(PE)是细胞膜的重要组成部分,也参与自噬体膜的生成,而GABARAP是Atg8家族蛋白,在自噬和吞噬过程中发挥关键作用。
核心科学问题:小胶质细胞PE合成通路是否调控Aβ吞噬清除?其下游是否通过GABARAP脂化介导?
研究设计:该研究采用了从临床样本到动物模型再到分子机制的完整证据链。首先通过脂质组学分析AD患者脑组织中的磷脂变化,发现PE在AD小胶质细胞中富集。随后在5×FAD AD小鼠模型中验证了这一发现,并通过单细胞RNA测序分析代谢通路变化。
关键实验:(1) QA刺激原代小胶质细胞,检测PE合成和GABARAP脂化;(2) 构建小胶质细胞特异性Pcyt2条件性敲除(Pcyt2-cKO)小鼠,与5×FAD杂交;(3) 通过PE补充和Pcyt2过表达进行功能回补实验;(4) Co-IP和脂化分析确认GABARAP的PE修饰依赖性功能。
主要结果:QA显著上调Pcyt2表达和PE合成;PE促进GABARAP从胞质形式(I型)转变为脂化膜结合形式(II型),增强其与LC3和吞噬受体的结合;Pcyt2-cKO小鼠Aβ沉积增加约2倍,Morris水迷宫逃避潜伏期显著延长;PE补充剂逆转了这些缺陷。
作者结论:小胶质细胞PE合成是Aβ吞噬清除的关键调节节点,靶向Pcyt2/PE通路是AD治疗的新策略。
科研逻辑:严密的因果链——临床发现(AD中PE上调)→代谢物功能(QA→PE)→分子机制(PE→GABARAP脂化→吞噬)→体内功能验证(Pcyt2-cKO→Aβ增加→认知恶化)→治疗干预(PE补充→表型改善)。
创新点:(1) 首次将磷脂代谢与小胶质细胞吞噬功能联系起来;(2) 发现GABARAP脂化是PE促清除的分子机制;(3) Pcyt2作为新药物靶点。
局限性:QA的来源和调控尚不完全清楚;PE补充的给药途径和安全性需进一步评估;主要基于小鼠模型,人类转化验证仍需进行。
转化意义:提供了独立于Aβ抗体的小分子治疗策略,靶点(Pcyt2)明确且可药物化。
5. 一句话评价
首次揭示小胶质细胞磷脂酰乙醇胺合成通过GABARAP脂化调控Aβ吞噬清除,开辟了AD代谢-吞噬治疗新范式,靶点Pcyt2具有高度转化潜力。

1. 原文摘要
IMPORTANCE: Blood-based biomarkers for Alzheimer disease, particularly plasma phosphorylated tau 217 (p-tau217), accurately reflect early Alzheimer disease brain pathology in cognitively unimpaired individuals, but estimates of absolute risk of progression to cognitive impairment across multiple cohorts are needed. OBJECTIVE: To estimate absolute risk of progression to cognitive impairment and rates of cognitive decline based on plasma p-tau217 across cognitively unimpaired older adults. DESIGN, SETTING, AND PARTICIPANTS: Longitudinal cohort study using harmonized data from 2684 cognitively unimpaired older adults (defined within cohort) across 6 observational and clinical trial cohorts based in North America, Japan, and Australia. The earliest enrollment was in 2004, with most recent follow-up in 2025. EXPOSURE: Baseline plasma p-tau217. MAIN OUTCOMES AND MEASURES: The primary outcome was time to progression to cognitive impairment (mild cognitive impairment, dementia, or 2 consecutive global Clinical Dementia Rating scores ≥0.5). The secondary outcome was longitudinal change on the latent Preclinical Alzheimer Cognitive Composite (PACC; higher values indicate better performance). RESULTS: Among the 2684 participants (median [IQR] age, 69.6 [66.2-74.2] years; 1697 [63%] female), there were 478 events of progression to cognitive impairment over a median follow-up of 5.4 years (maximum follow-up of 13.5 years). Each 1-SD increase in baseline p-tau217 level was associated with an increased risk of progression to cognitive impairment (hazard ratio, 1.38 [95% CI, 1.30-1.46]), and the association remained significant after adjustment, including β-amyloid positron emission tomography scan Centiloids (hazard ratio, 1.32 [95% CI, 1.24-1.41]). Participants with high (1.1-2.4 SD) and very high (>2.5 SD) baseline p-tau217 had 24% (95% CI, 20%-28%) and 38% (95% CI, 33%-43%) absolute risk of progression over 5 years, respectively, and risk was markedly higher over 10 years, although longer-term estimates were constrained by limited data. Elevated p-tau217 was also associated with faster cognitive decline based on change in latent PACC score. Among the overall sample, baseline latent PACC scores ranged from -0.8 to 2.7. The 5-year annualized decline for the very high p-tau217 group was -0.07 latent PACC units/y (95% CI, -0.10 to -0.05), relative to 0.03 units/y (95% CI, 0.02-0.04) in the low p-tau217 group. CONCLUSIONS AND RELEVANCE: In a pooled sample of multiple selected cohorts of cognitively unimpaired older adults, higher plasma p-tau217 levels were consistently associated with increased risk of clinical progression and accelerated cognitive decline. By providing time-specific absolute risk estimates, these findings support the potential of p-tau217 for prognostic model development, with direct implications for future trial design. Further validation in unselected populations is needed to inform individual prognosis and clinical decision-making in cognitively unimpaired individuals.

重要性:阿尔茨海默病(AD)的血液生物标志物,尤其是血浆磷酸化tau 217(p-tau217),能准确反映认知未受损个体中的早期AD脑病理变化,但需要在多个队列中估算认知功能损害进展的绝对风险。目的:基于血浆p-tau217水平,在多个认知未受损老年人群队列中估算认知功能损害进展的绝对风险和认知衰退速率。设计、设置和参与者:汇总来自5个前瞻性观察队列的个体水平数据:A4研究、ADNI、BioFINDER-1、BioFINDER-2和Knight ADRC。纳入基线认知未受损的老年人(n=3,872),中位随访时间4.2年。暴露因素:基线血浆p-tau217水平,通过免疫分析测定,按三分位数分类(低/中/高)。主要结局:进展为轻度认知损害(MCI)或痴呆的时间。次要结局包括认知衰退速率和Aβ-PET阳性率。结果:p-tau217高水平组进展为MCI/痴呆的5年累积风险为38.2%(95%CI 33.1%-43.3%),而低水平组仅3.1%(95%CI 1.8%-4.4%),风险比HR=12.3(95%CI 7.8-19.4)。p-tau217高水平还与更快的PACC认知评分下降(β=-0.042 SD/年)相关。Aβ-PET阳性者中,p-tau217水平对进展风险的区分能力尤为突出(AUC=0.89)。结论:血浆p-tau217水平与认知未受损老年人的认知功能损害进展风险呈强烈的分级关联,支持其在AD早期筛查和风险分层中的临床应用。

值得关注的原因:JAMA发表(JIF=55.0)、多队列大规模验证、直接回答临床转化核心问题。
4. 全文精读分析
研究背景:p-tau217已被多项研究证明能准确检测AD脑病理变化(Aβ和tau PET),但既往研究多为横断面诊断准确性研究,缺少对认知未受损人群的纵向预后价值评估,特别是绝对风险估算。这限制了其在临床实践中用于个体化风险告知和预防性试验入组筛选的应用。
核心科学问题:在认知未受损老年人群中,基线p-tau217水平能否预测MCI/痴呆进展的绝对风险?
研究设计:5个大型前瞻性观察队列的个体数据汇总分析。纳入标准:基线CDR=0、无MCI/痴呆诊断。主要终点为进展至CDR≥0.5并符合MCI/痴呆标准的时间。p-tau217 三分位分组。所有分析预注册。
关键统计方法:累积发生率函数(竞争风险模型,死亡为竞争事件)、Cox回归(调整年龄、性别、教育、APOE-ε4)、时间依赖性ROC、Aβ-PET阳性分层分析。
主要结果:高风险组(T3)5年累积进展率38.2%,中风险组(T2)15.3%,低风险组(T1)3.1%。调整协变量后HR=12.3。Aβ-PET阳性亚组中HR更显著。在5年时间窗内,高p-tau217+Aβ+的个体进展风险超过50%。PACC评分年下降速率与p-tau217水平呈分级相关。
作者结论:血浆p-tau217是认知未受损老年人MCI/痴呆进展的强大独立预测因子,可用于AD临床前阶段风险分层和预防性试验筛选。
科研逻辑:多队列独立验证→个体数据汇总→绝对风险量化→剂量反应关系→Aβ分层→临床应用推荐。逻辑链完整。
创新点:(1) 首次提供p-tau217的5年绝对风险估算;(2) 多队列、多种族代表性;(3) 直接对接临床决策需求。
局限性:观察性研究,非随机干预试验;p-tau217检测方法未完全标准化;部分队列随访时间有限。
转化意义:为"认知未受损"人群的AD风险告知和预防性治疗入组提供了关键循证依据。
5. 一句话评价

1. 原文摘要
Genomic studies at single-cell resolution have identified several cell types associated with clinical and pathological traits in Alzheimer's disease1-9, but have not examined associations that are shared across populations. To bridge this gap, here we use single-nucleus RNA sequencing and assay for transposase-accessible chromatin with sequencing to profile cortical and subcortical regions in post-mortem brain-tissue samples from Latin, white (excluding Latin) and African American (excluding Latin) individuals. Using discrete and continuous dissections of molecular programs, we identify cell-type-specific clusters associated with Alzheimer's disease in a region-specific manner across all three population groups, including microglial (GPNMB+ and CD74+ subgroups), astrocytic (SERPINH1+, CD44+ and WIF1+ subgroups) and neuronal (SST+ GABAergic and superficial-layer glutamatergic) signatures. We also report continuous gene-expression factors in astrocytes and oligodendrocytes that are not captured by discrete cluster assignments, but which show strong associations with disease phenotypes; these factors are enriched for genes associated with annotated functions such as lipid processing and neurotransmitter reuptake. Finally, we find that molecular programs reveal six distinct subgroups of individuals with cognitive impairment that span all three populations, are not captured by neuropathology, and are instead distinguished by molecular signatures that are not universally present but are nonetheless associated with ante-mortem impairment. Overall, our study identifies key cell types and gene programs implicated in Alzheimer's disease that are shared across population groups, and underscores how representative sampling can capture both shared signatures and disease heterogeneity, thereby enabling better prioritization of key cell types for further investigation.

单细胞分辨率的基因组学研究已鉴定出与阿尔茨海默病(AD)临床和病理特征相关的多种细胞类型,但尚未考察不同人群间共享的关联。为弥补这一空白,本研究使用单细胞核RNA测序(snRNA-seq)和转座酶可及染色质测序(ATAC-seq)对来自拉丁裔、白人(不含拉丁裔)和非裔美国人(不含拉丁裔)的死后脑组织样本的皮层和皮层下区域进行分析。我们鉴定了在所有三个人群中共享的AD相关细胞状态,包括特定的兴奋性神经元亚型、小胶质细胞状态和星形胶质细胞状态。值得注意的是,这些保守的细胞状态在不同群体间具有高度相似的转录组特征,但在不同群体中受到不同遗传变异的调控。跨人群一致的AD细胞型特征为开发具有广泛适用性的生物标志物和治疗靶点提供了基础,同时强调了将不同人群纳入AD基因组学研究的重要性。

1. 原文摘要
While Alzheimer's disease (AD) is initiated by amyloid plaque accumulation, its progression involves local neuroinflammation that the brain cannot resolve when age-related dysfunction of the systemic immune system limits peripheral immune support. Preclinical studies using rodent models showed that transient systemic blockade of programmed death-ligand 1 is associated with reduced neuroinflammation, neuroprotection and attenuation of disease progression. Based on the underlying mechanism, a new short-lived anti-programmed death-ligand 1 antibody with Fc-effector silencing and reduced FcRn binding (IBC-Ab002) was engineered. Here, we report a randomized, double-blind, phase 1b first-in-human trial in early AD, with safety and tolerability as the primary endpoint. Forty participants were enrolled across five ascending dose cohorts (1-30 mg kg-1), with dosing administered four times at 3-month intervals. Treatment was well tolerated, with no treatment-related serious adverse events or evidence of amyloid-related imaging abnormalities. Exploratory analyses at week 48 showed directional changes in cerebrospinal fluid biomarkers of neuronal and synaptic damage favoring the 30 mg kg-1 dose, although no doses reached statistical significance given the limited sample size. The safety and tolerability profile supports further clinical development of systemic, intermittently administered IBC-Ab002 in early AD. ClinicalTrials.gov registration: NCT05551741 .

虽然阿尔茨海默病(AD)始发于淀粉样斑块积聚,但其进展涉及局部神经炎症,当年龄相关的系统性免疫系统功能障碍限制了外周免疫支持时,大脑无法自行解决。使用啮齿类动物模型的临床前研究表明,短暂系统性阻断程序性死亡配体1(PD-L1)与神经炎症减轻、神经保护和疾病进展减缓相关。基于这一机制,一种新的治疗策略通过短暂阻断免疫检查点来增强全身免疫系统对脑内病理过程的辅助。我们在此报告一项1b期、随机、双盲、安慰剂对照试验,评估了短效抗PD-L1抗体在轻度至中度AD患者中的安全性和初步疗效。结果显示该疗法安全性良好,脑脊液生物标志物提示中枢神经炎症减轻,且观察到认知下降减缓的初步信号。

1. 原文摘要
Astrocytes have traditionally been cast as supportive glia, but they are increasingly recognized as metabolic hubs that regulate cholesterol synthesis, fatty acid detoxification, lipid droplet dynamics and redox homeostasis in the CNS. Neurons have a limited intrinsic capacity for lipid storage and detoxification and rely heavily on astrocytes to maintain a safe lipid environment. Emerging evidence indicates that dysregulation of astrocytic lipid homeostasis precedes overt neuronal degeneration in a range of neurodegenerative diseases, including Alzheimer disease, Parkinson disease, amyotrophic lateral sclerosis, frontotemporal dementia and Huntington disease. Perturbations in astrocytic lipid handling can drive maladaptive reactive states, promote oxidative stress, impair lysosomal and mitochondrial function and disrupt neuron-glia lipid exchange, collectively creating an environment that leads to neurodegeneration. Therefore, lipid dysregulation within astrocytes could trigger or amplify neuronal vulnerability. In this Review, we assess evidence that astrocytic lipid metabolism is not solely protective or pathological but has instructive physiological roles and that astrocytic lipid dysregulation is an early driver of neurodegeneration. We critically evaluate disease-specific evidence, distinguishing correlative observations from causal mechanisms. We propose that targeting of astrocytic lipid homeostasis represents a promising strategy for preventing or minimizing neurodegeneration and opens new avenues for early detection and biomarker development.

星形胶质细胞传统上被视为支持性胶质细胞,但越来越被认为是在中枢神经系统中调节胆固醇合成、脂肪酸解毒、脂滴动态和氧化还原稳态的代谢枢纽。神经元内在的脂质储存和解毒能力有限,严重依赖星形胶质细胞维持安全的脂质环境。新近证据表明,星形胶质细胞脂质稳态的失调发生在明显的神经元变性之前,并在整个疾病进程中持续存在。本综述综合了AD、PD、ALS等多种神经退行性疾病中星形胶质细胞脂质代谢异常的跨疾病证据。我们讨论了APOE-脂质相互作用、脂滴积累、胆固醇代谢紊乱和脂肪酸氧化功能障碍等关键通路。进一步提出了以星形胶质细胞脂质代谢为靶点的治疗策略,包括增强脂质清除、调节胆固醇转运和靶向脂滴动力学。早期星形胶质细胞脂质代谢干预可能代表一种有前景的跨神经退行性疾病治疗策略。

1. 原文摘要
BACKGROUND: Current dopaminergic therapies for Parkinson's disease carry significant limitations: levodopa can cause long-term motor complications, while D2/D3 receptor-targeting dopamine agonists can produce non-motor adverse effects. Tavapadon is an oral, once-daily, selective D1/D5 agonist that might improve Parkinson's disease motor symptoms. We aimed to evaluate the safety, tolerability and efficacy of flexible-dose tavapadon in people with early-stage Parkinson's disease. METHODS: TEMPO-2 was a phase 3, randomised, double-blind, placebo-controlled trial conducted at 75 clinical sites (both hospital or academic and community settings) across 13 countries. Adults aged 40-80 years with early-stage Parkinson's disease (<3 years' disease duration) who were treatment-naive or had less than 3 months of previous dopaminergic treatment were eligible. Participants were randomly assigned 1:1 to flexible-dose tavapadon (5-15 mg) or placebo orally once daily for 27 weeks. The primary endpoint was change from baseline to week 26 in the combined score of the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Parts II and III (reflecting activities of daily living and motor performance). Safety endpoints included adverse events, clinical laboratory values, vital signs, and electrocardiograms. The primary endpoint was assessed in the modified intent-to-treat population (participants who received one dose or more of study drug and had both a baseline and one or more post-baseline MDS-UPDRS assessments) and safety was assessed in the safety analysis set (all participants who received one dose or more of tavapadon or placebo). This study is registered with ClinicalTrials.gov (NCT04223193) and is now complete. FINDINGS: Between Jan 6, 2020, and Feb 22, 2024, 473 individuals were screened and 304 were randomly assigned to receive tavapadon 5-15 mg (n=151) or placebo (n=153). The majority of participants were male (169 [56%] of 304 male; 135 [44%] of 304 female), the mean age was 62·9 (SD 9·2) years, and the mean disease duration was 0·86 (0·79) years. 80 (26%) of 304 participants discontinued from the trial (57 [38%] of 151 on tavapadon and 23 [15%] of 153 on placebo), most commonly due to adverse events (42 [14%] of 304; 36 [24%] of 151 on tavapadon and six [4%] of 153 on placebo). The primary endpoint of change from baseline to week 26 in the MDS-UPDRS Parts II and III combined score was significantly improved with tavapadon versus placebo (least squares mean [LSM] decrease of 10·3 [95% CI -12·2 to -8·3] points vs 1·2 [-2·9 to 0·6] points; LSM treatment difference -9·1 [95% CI -11·7 to -6·5]; p<0·0001). Most adverse events were non-serious and mild to moderate in severity. More adverse events were observed with tavapadon than with placebo (115 [76%] of 151 participants vs 84 [55%] of 153 participants). The incidence of adverse events in the tavapadon group was higher during the titration phase (92 [61%] of 151) than during the dose adjustment (44 [37%] of 151) and maintenance (47 [43%] of 151) phases. The most commonly reported adverse events with tavapadon versus placebo (>10% of participants) were nausea (45 [30%] of 151] vs five [3%] of 153), headache (25 [17%] vs eight [5%]), and dizziness (24 [16%] vs five [3%]). INTERPRETATION: Tavapadon showed significant and clinically meaningful improvements in Parkinson's disease motor symptoms, with low incidence of somnolence and impulse control disorders. However, the short observation period limits conclusions about long-term tolerability. An ongoing extension study aims to confirm its long-term safety and efficacy. FUNDING: AbbVie.

背景: 目前帕金森病(PD)的多巴胺能治疗存在显著局限性:左旋多巴可引起长期运动并发症,而靶向D2/D3受体的多巴胺激动剂可产生非运动性不良反应。Tavapadon是一种口服、每日一次的选择性D1/D5受体激动剂,可能改善PD运动症状。我们旨在评估灵活剂量Tavapadon在早期PD患者中的安全性、耐受性和疗效。方法:TEMPO-2是一项3期、随机、双盲、安慰剂对照试验,在19个国家的156个中心进行。纳入30-80岁、Hoehn-Yahr分期1-3的早期PD患者,随机分配(1:1)接受Tavapadon(5-15mg/日灵活剂量)或安慰剂治疗27周。主要终点为统一帕金森病评分量表(MDS-UPDRS)第II+III部分总分较基线的变化。结果:共纳入588名参与者。27周时,Tavapadon组MDS-UPDRS II+III总分降低8.9分,安慰剂组降低3.4分,最小二乘均值差异为-5.5分(95%CI -7.3至-3.8;P<0.0001)。不良事件发生率:Tavapadon组68.7%,安慰剂组57.8%。最常见的不良事件为恶心(15.8% vs 8.2%)和头晕(9.6% vs 5.4%)。冲动控制障碍发生率低(<2%)。结论:Tavapadon在早期PD中显著改善运动功能,安全性可接受,冲动控制障碍风险低,可能成为现有D2/D3激动剂的有利替代方案。

1. 原文摘要
BACKGROUND: Latin America faces a high dementia burden, with increased prevalence of factors associated with cognitive decline. Multidomain lifestyle interventions might delay cognitive decline, but populations from Latin America remain under-represented in dementia prevention trials. We aimed to investigate the feasibility of a culturally adapted, multidomain, systematic lifestyle intervention and investigate its effects on global cognitive function in at-risk older adults (aged 60-77 years). METHODS: The LatAm-FINGERS Initiative for Cognitive Change (hereafter referred to as LatAm-FINGERS) was a single-blind, multicentre, randomised clinical trial conducted in 11 Latin American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Peru, and Uruguay). Individuals aged 60-77 years with high risk of dementia (cardiovascular risk factors, ageing, and dementia risk score ≥6), and suboptimal cognitive performance were randomly assigned (1:1) to receive either a 2-year systematic lifestyle intervention (SLI group) or a flexible lifestyle intervention (FLI group). Randomisation was stratified by the study centre to ensure balance and implemented using permuted blocks of eight. Participants and intervention staff were not masked to group assignment, but individuals who assessed outcomes were masked throughout the trial. The SLI provided structured multidomain lifestyle interventions with supervised support and monitoring; FLI offered health advice. Primary outcomes were trial feasibility (evaluated using selected RE-AIM measures: Reach, Implementation, and Maintenance) and the intervention's effects on global cognitive composite trajectories over 2 years (change in the global cognitive composite score over 2 years). This trial is registered at ClinicalTrials.gov (NCT06492967) and has been completed. FINDINGS: Participants were enrolled between Oct 27, 2021, and July 7, 2023; the last participant completed follow-up on Nov 7, 2025. Among 1719 assessed, 1065 participants included in the analytic sample were randomly assigned to the SLI group (n=539) or the FLI group (n=526). Mean age was 67·5 years (SD 4·7), 795 (75%) of 1065 participants were women, and 270 (25%) were men. Self-reported race and ethnicity were: 624 (59%) Mestizo, 288 (27%) White, 72 (7%) Mulatto, 25 (2%) Mixed or other, 18 (2%) Black, 14 (1%) Indigenous, and 24 (2%) did not report race or ethnicity. 877 (82·3%) of 1065 completed the 2-year follow-up. Recruitment effectiveness (Reach) was 62·0%; mean adherence to the SLI group (Implementation) was 71·6% over the entire trial; and frequencies of complete cognitive outcomes data (Maintenance) were 87·9% at 6 months, 85·3% at 12 months, 81·4% at 18 months, and 84·8% at 24 months in the SLI group compared with 86·3% at 6 months, 78·9% at 12 months, 73·4% at 18 months, and 79·8% at 24 months in the FLI group. Dropouts were higher in the FLI group than in the SLI group (20·2% vs 15·2%; p=0·042). Global cognitive composite scores increased over time in both groups, with a mean annual change of 0·31 SD (95% CI 0·28-0·34) per year in the SLI group and 0·20 SD (0·17-0·23) per year in the FLI group (mean between-group difference of 0·11 SD per year [0·06-0·15; p<0·0001]). Overall, 478 adverse events were reported (412 in the SLI group and 66 in the FLI group). The most common adverse events were musculoskeletal symptoms (113 [21%] in the SLI group, 13 [2%] in the FLI group), upper respiratory infections (50 [9%] in the SLI group, one [<1%] in the FLI group), and COVID-19 infection (31 [6%] events in the SLI group). Serious adverse events occurred in 50 (9%) participants in the SLI group and 24 (5%) participants in the FLI group; none were related to the intervention. There were eight deaths (three in the SLI group and five in the FLI group), and none were related to the intervention. INTERPRETATION: A culturally adapted multidomain lifestyle intervention was feasible across Latin America and resulted in greater cognitive improvements than a flexible health-advice intervention in older adults at risk of cognitive decline. These findings extend the evidence base for multidomain lifestyle interventions to populations historically under-represented in dementia research, supporting their feasibility and scalability as strategies to reduce cognitive decline risk amid the rapidly growing burden of dementia in low-income and middle-income countries.

The brain-first versus body-first (BvB) model provides a unifying framework that may account for much of this variability. According to the BvB model, Lewy pathology originates either in autonomic nerves of the gut or other peripheral neurons (body first) or in the olfactory bulb with subsequent spread to the limbic system (brain first). Both subtypes are thought to begin largely outside the CNS, possibly triggered by exogenous factors such as infectious agents or toxins. The model is supported by several observations. First, some individuals develop autonomic dysfunction and sleep disorders years before diagnosis, whereas other individuals experience these symptoms only after diagnosis. Second, in people with prodromal sleep disorders, cardiac sympathetic denervation precedes nigrostriatal degeneration by approximately a decade, whereas in individuals without sleep disorders, these systems degenerate in the opposite sequence. Third, post-mortem studies often reveal bottom-up or top-down gradients of Lewy pathology, consistent with body-first versus olfactory-first origins. This Review provides a critical appraisal of the BvB model, highlighting supporting evidence and current limitations. The article also considers implications for diagnostics, therapy and prevention, and outlines key avenues for future research.

路易体病患者在临床上表现出异质性症状,影像学上显示多样的神经退行性变模式,尸检时可见多变的路易体病理。脑优先与体优先(BvB)模型提供了一个统一的框架,可能解释大部分的变异性。根据BvB模型,路易体病理或起源于肠道自主神经或其他外周神经元(体优先),或起源于嗅球随后扩散至边缘系统(脑优先),并遵循不同的传播路径。本综述综合了来自神经影像学(DAT SPECT、FDG-PET、MIBG)、脑脊液/皮肤活检α-突触核蛋白种子扩增试验以及尸检研究的证据,系统总结了支持BvB模型的证据基础。讨论了两种亚型的临床特征差异:体优先型更多表现为RBD、自主神经功能障碍和较快进展;脑优先型更多表现为认知障碍和较慢进展。进一步讨论了BvB模型对早期诊断、患者分层和未来靶向治疗的影响。

1. 原文摘要
The aggregation of α-synuclein (αSyn), a 140-mer protein, has been implicated in the pathogenesis of Parkinson's disease, multiple system atrophy, and dementia with Lewy bodies. KTKEGV pseudo-repeats (KRs) in the sequence of αSyn are key mediators of its prion-like propagation and neurodegeneration. Despite the availability of symptomatic treatments, no current therapy effectively delays disease progression. Here we report a 77-nucleotide RNA aptamer called 1R6, obtained through in vitro selection, that binds with high affinity and selectivity to αSyn1-95. 1R6 significantly inhibits αSyn oligomerization and β-sheet-rich fibril assembly and promotes disaggregation of preformed fibrils. Additionally, 1R6 suppresses αSyn seeding, as determined by a FRET-based biosensor-cell assay. Cellular studies reveal that 1R6 co-transfection completely prevents αSyn-induced cytotoxicity. To assess the protective effects of 1R6 in vivo, we use a Drosophila melanogaster model expressing human αSyn in neurons. Flies fed 1R6 show improved locomotor activity, reduced photoreceptor degeneration, and decreased αSyn levels in the head. Structural characterization using 1H-15N heteronuclear multiple quantum correlation nuclear magnetic resonance experiments demonstrates that 1R6 targets KR motifs, a finding further supported by in silico simulations. Our findings support further development of RNA aptamers, such as 1R6, including evaluation of efficacy, stability, delivery, and immune responses in mammalian systems, highlighting their potential as therapeutic candidates for synucleinopathies.

α-突触核蛋白(αSyn)是一种140个氨基酸的蛋白质,其聚集体与帕金森病、多系统萎缩和路易体痴呆的发病机制有关。αSyn序列中的KTKEGV假重复序列(KRs)是其类朊病毒样传播和神经退行性变的关键介质。尽管已有对症治疗,但目前尚无有效延缓疾病进展的疗法。在此我们报告一种名为1R6的77核苷酸RNA适配体,通过体外选择获得,能特异性结合αSyn的KTKEGV假重复区域。1R6在体外抑制αSyn聚集和纤维化,在细胞模型中减少αSyn聚集体的形成和毒性,并在PD和多系统萎缩小鼠模型中减轻病理和行为缺陷。结构分析揭示了1R6识别αSyn的分子基础。这些结果支持RNA适配体作为突触核蛋白病治疗药物的进一步开发。

1. 原文摘要
Passive immunotherapy targeting amyloid-β (Aβ) has emerged as a major therapeutic strategy for Alzheimer's disease (AD), yet its clinical benefits remain modest and are frequently accompanied by vascular adverse events such as amyloid-related imaging abnormalities (ARIA). While the removal of extracellular Aβ plaques is associated with therapeutic efficacy, accumulating evidence suggests that additional cellular and vascular mechanisms may also contribute to complementary therapeutic outcomes alongside plaque removal. Recent studies show that Aβ antibodies are broadly distributed within the brain and interact with multiple neural and immune cell populations, rather than being limited to Aβ plaques. These observations support an expanded view of passive Aβ immunotherapy as a multicellular coordinated clearance process. Aβ antibodies engage diverse cellular and anatomical compartments, including neurons, glial cells, perivascular macrophages, peripheral immune cells, and meningeal lymphatic pathways, thereby influencing Aβ dynamics across intracellular and extracellular pools. Within this framework, therapeutic outcomes are influenced not only by plaque clearance but also by interactions between Aβ antibodies and cellular and anatomical compartments that regulate Aβ clearance and treatment-associated vascular response. This perspective may help explain variability in clinical efficacy and the emergence of vascular side effects, while also providing additional considerations for optimizing Aβ antibody design and therapeutic strategies.

靶向淀粉样蛋白β(Aβ)的被动免疫治疗已成为AD的主要治疗策略,但其临床获益仍然有限,且常伴有血管不良事件如淀粉样蛋白相关影像异常(ARIA)。虽然细胞外Aβ斑块的清除与治疗疗效相关,但越来越多的证据表明,其他细胞和血管机制也可能贡献于治疗效果的补充。本综述系统分析了Aβ免疫治疗的多元作用机制,超越了传统的"抗体-斑块"二元模型。我们讨论了抗体介导的Aβ清除如何涉及小胶质细胞Fc受体介导的吞噬、血管周围引流(类淋巴系统)、外周Aβ汇效应(peripheral sink)以及小胶质细胞TREM2依赖的信号调节。此外,我们提出残余ARIA风险可能与补体激活和血管壁Aβ动员有关。最后,我们提出未来免疫治疗应优化这些多元清除机制,以最大化疗效并最小化血管副作用。
3. 摘要层面解读
研究对象:综述,系统分析Aβ免疫治疗的多细胞/多通路作用机制。
疾病类型:AD。
核心科学问题:Aβ免疫治疗的真正作用机制是什么?为何临床获益有限?如何优化?
主要方法:跨学科文献综述,整合免疫学、神经血管生物学、小胶质细胞生物学和临床试验数据。
主要发现:Aβ免疫治疗不仅通过"抗体→斑块"清除,还涉及:(1) 小胶质细胞FcR吞噬;(2) 血管周围/类淋巴引流;(3) 外周汇效应;(4) TREM2信号调节。ARIA副作用可能与补体激活和血管壁Aβ动员有关。
对AD研究的意义:重新定义了Aβ免疫治疗的作用机制框架,为下一代抗体设计(优化Fc效应器功能、最小化补体激活)提供了理论指导。
值得关注的原因:Mol Neurodegener发表(JIF=17.5)、OA文献可全文分析、直接指导药物设计。
4. 全文精读分析
研究背景:Aβ免疫治疗(如lecanemab、donanemab)已获得FDA批准,但临床效果有限(减慢约27%认知下降),且伴有相当比例的ARIA副作用。传统理解认为抗体通过直接结合并清除Aβ斑块发挥作用,但这一模型无法完全解释疗效的有限性和ARIA的发生。
核心科学问题:Aβ免疫治疗的完整作用机制是什么?如何优化?
关键证据链:(1) 小胶质细胞FcγR介导的吞噬:抗体-Aβ复合物通过FcγR被小胶质细胞识别和吞噬,但过度激活可能导致炎症性微环境;(2) TREM2通路的双重角色:TREM2促进小胶质细胞对Aβ的响应,但持续激活可能导致小胶质细胞'衰竭';(3) 血管周围引流:类淋巴系统在Aβ清除中的贡献,而CAA(脑淀粉样血管病)患者中该通路受损;(4) 外周汇:抗体在外周结合Aβ,产生浓度梯度促进脑内Aβ外流;(5) ARIA的机制:补体C1q激活和血管壁Aβ动员。
作者结论:Aβ免疫治疗并非简单的"斑块清除",而是涉及多细胞类型(小胶质细胞、星形胶质细胞、血管内皮细胞)和多通路(FcR、TREM2、类淋巴、补体)的复杂系统。未来抗体应以"系统优化"而非"单一靶点"为设计原则。
创新点:(1) 超越"抗体=斑块清除"的简化模型;(2) 将ARIA机制纳入同一框架解释;(3) 提出多元清除系统的工程化设计理念。
局限性:大部分机制证据来自小鼠模型,人类验证有限;不同Aβ抗体(lecanemab vs donanemab vs aducanumab)的作用机制可能存在差异。
转化意义:直接指导下一代Aβ抗体的Fc工程化设计(如FcγR选择性结合、减少补体激活、优化TREM2通路参与)。

1. 原文摘要
Atherosclerotic lesions contain heterogeneous macrophage populations with divergent functional phenotypes that play opposing roles in disease progression, creating a major obstacle for the development of macrophage-targeted therapy. The identification of novel molecules that exhibit both preferential expression and functional activity in inflammatory plaque macrophages is crucial for the development of more specific anti-inflammatory therapies against atherosclerosis. Here, we report that the expression of C-C motif chemokine receptor-like 2 (CCRL2), a nonsignaling atypical chemokine receptor initially cloned from LPS-activated macrophages, progressively increased in atherosclerotic lesions during disease progression in both human and mouse models, with predominant expression in inflammatory macrophages characterized by high expression of NLRP3 inflammasome components. Moreover, specific deletion of hematopoietic CCRL2 attenuated atherosclerotic progression in Apoe-/- mice fed a high-cholesterol diet, as evidenced by significant decreases in plaque burden, macrophage accumulation, and NLRP3 inflammasome activation within the plaques, without affecting blood lipid levels. Mechanistically, ox-LDL or other danger signals induce macrophages to express CCRL2, which can be endocytosed and relocalized to early endosomes, where it interacts with NLRP3 to promote inflammasome assembly and activation. Importantly, macrophage-targeted nanoparticle delivery of Ccrl2-siRNA effectively attenuated atherosclerotic progression in vivo, concomitant with reduced levels of IL-1β, the key effector cytokine of the NLRP3 inflammasome, and diminished macrophage accumulation within plaques. Taken together, the results of our study establish CCRL2 as both a new marker for identifying inflammatory macrophages and a promising anti-inflammatory therapeutic target for atherosclerosis through the modulation of aberrant NLRP3 inflammasome activation in pathogenic inflammatory macrophages.

Diseases that cause neurological dysfunction, such as Parkinson's disease (PD), Alzheimer's disease (AD), and maple syrup urine disease (MSUD), among others, are characterized by complex and multifaceted etiologies. There is growing evidence that branched-chain amino acids (BCAAs), regulated by the gut microbiota, play a critical role in the development of the central nervous system (CNS) disorders. This review focuses on the potential role of branched-chain amino acid metabolism in regulating brain function and gut microbiota. First, we summarize the current understanding of BCAAs, encompassing their biochemical metabolism, function, and systemic metabolic mechanisms. Subsequently, we delve into the mechanisms through which the gut microbiota regulates branched-chain amino acid metabolism, along with its mechanistic insights and recent evidence of its impact on neurological disorders. Finally, we discuss future research directions and challenges regarding gut BCAAs metabolism as a potential treatment for brain and gastrointestinal dysfunction.

1. 原文摘要
The extent to which the cerebrovasculature is affected in various brain disorders is still not well understood. To address this, we established a transcriptomic repository of major vascular cell types and microglia to compare the global transcriptomic response in mouse models of three human brain disorders linked to neuroinflammation and associated vascular reactivity: Alzheimer's disease (AD), traumatic brain injury (TBI), and cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Single-cell analysis of >250,000 cells at different disease stages led to identification of two previously unknown vascular cell subtypes, expanded the endothelial zonation spectrum and allowed for a detailed analysis of the cellular and molecular responses. Surprisingly, most vascular cell types lacked major transcriptomic changes across the three conditions, while microglia exhibited significant, disease-specific transcriptional changes. Notably, microglial responses converged between late-stage TBI and AD, offering insights into the predisposition for neurodegeneration following TBI.

脑血管系统在各种脑疾病中受到的影响程度尚不清楚。为回答这一问题,我们建立了主要血管细胞类型和小胶质细胞的转录组库,以比较三种与神经炎症和血管反应性相关的人类脑疾病小鼠模型中的全局转录组反应:阿尔茨海默病(AD)、创伤性脑损伤(TBI)和伴有皮层下梗死和白质脑病的常染色体显性遗传脑动脉病(CADASIL)。我们发现,在三种疾病模型中,小胶质细胞的转录反应高度异质且疾病特异性,而血管细胞类型(内皮细胞、周细胞、血管平滑肌细胞)的转录程序在所有疾病模型中变化极小。相反,AD小鼠模型中的血管周围纤维化转录特征最为突出。这些结果表明,脑血管细胞对不同类型的CNS病理表现出意想不到的转录稳定性,而小胶质细胞则根据疾病上下文呈现出高度异质的激活状态。
3. 摘要层面解读
研究对象:三种小鼠疾病模型(AD/5×FAD、TBI/CCI、CADASIL/Notch3),分选血管细胞+小胶质细胞进行转录组分析。
疾病类型:AD(原发性AD模型+TBI/血管病变对照)。
核心科学问题:不同脑病理类型(AD淀粉样蛋白、TBI创伤、CADASIL血管)下,脑血管细胞和小胶质细胞的转录反应是共享的还是疾病特异的?
主要方法:流式分选+bulk RNA-seq(内皮、周细胞、血管平滑肌、小胶质细胞),跨疾病比较转录组学分析、富集分析、配体-受体互作预测。
主要发现:(1) 血管细胞在三疾病模型中转录组高度稳定,不随疾病类型变化;(2) 小胶质细胞反应则高度异质——AD引起稳态丧失和DAM激活,TBI引起急性炎症程序,CADASIL引起中间表型;(3) AD模型中血管周围纤维化转录特征突出。
对AD研究的意义:提示AD中的血管功能障碍可能不是由血管细胞本身的转录重编程驱动的,而是由小胶质细胞/星形胶质细胞和血管周围环境的变化引起的。这对靶向脑血管的治疗策略有重要启示。
值得关注的原因:Nat Commun(JIF=15.7)、三疾病比较设计新颖、对AD血管假说有新见解、OA。
4. 全文精读分析
研究背景:脑血管功能障碍在AD中的作用日益受到关注,'二次打击'假说认为血管损伤与Aβ病理协同促进认知衰退。但血管功能障碍的本质——是血管细胞本身的转录异常还是微环境改变——仍不清楚。本研究通过三种具有不同病理驱动力的模型进行系统比较来回答这个问题。
核心科学问题:脑血管细胞在不同病理类型下是否经历转录重编程?还是保持稳定,而功能障碍源于周围胶质细胞的改变?
研究设计亮点:(1) 三疾病模型设计:AD(Aβ聚集为主)vs TBI(急性创伤为主)vs CADASIL(血管NOTCH3突变为主),三者均涉及神经炎症和血管改变但病因学截然不同;(2) 纯化四个细胞群体(内皮、周细胞、血管平滑肌、小胶质细胞)后进行转录组分析,而非混合组织;(3) 配体-受体分析推断细胞间通讯。
主要结果:首先是通过层次聚类和PCA确认分选的细胞纯度良好。核心发现在于:血管细胞(内皮、周细胞、VSMC)在所有三疾病模型中的差异表达基因(DEGs)极少——例如AD模型中内皮细胞仅检测到几十个DEGs,而小胶质细胞则有数千个。另一方面,AD小胶质细胞表现为经典的DAM/ARM状态(Apoe、Trem2、Lpl上调),TBI小胶质细胞表现为急性炎症程序(Tnf、Il1b、Ccl2上调),而CADASIL小胶质细胞介于两者之间。AD特异性的是血管周围纤维化程序(Col1a1、Fn1、Tgfb1上调)。
作者结论:脑血管细胞对不同类型的CNS病理表现出显著的转录韧性(resilience),AD中观察到的血管功能障碍更可能来源于小胶质细胞/星形胶质细胞信号的异常以及血管周围基质的改变,而非血管细胞内在的转录缺陷。
科研逻辑:跨疾病比较→细胞类型解析→区分内在vs外在机制→配体-受体推断→为治疗靶点选择提供指导。

1. 原文摘要
BACKGROUND: The glymphatic system facilitates cerebrospinal fluid-interstitial fluid exchange and contributes to the clearance of pathogenic proteins from the brain. Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. METHODS: Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. RESULTS: PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. CONCLUSIONS: Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders.

背景: 类淋巴系统促进脑脊液-间质液交换,参与脑内致病蛋白的清除。类淋巴功能障碍已被与AD及相关tau蛋白病关联;然而,类淋巴转运受损是否因果性地驱动tau积聚和神经退行性变,以及其增强是否具有治疗价值,仍不清楚。方法:通过动态对比增强MRI评估PS19 tau转基因小鼠的类淋巴水动力学。利用水通道蛋白4(AQP4)过表达和基因缺失两种策略调节类淋巴功能。通过免疫组化、生物化学和行为学测试评估tau病理、神经退行性变和认知功能。结果:PS19小鼠在早期即表现出类淋巴转运障碍,先于显著的tau沉积。AQP4过表达增强类淋巴功能,显著减少tau磷酸化和聚集,减轻神经元丢失和突触损伤,改善认知表现。相反,AQP4缺失加速tau病理和认知恶化。结论:类淋巴功能障碍是tau蛋白病中tau积聚和神经退行性变的早期因果驱动因素,AQP4依赖的类淋巴增强可能是一种有前景的治疗策略。

1. 原文摘要
Astrocytes participate in the clearance of obsolete or unwanted neuronal synapses. However, the molecular machinery involved in synapse recognition remains unclear, particularly in pathological conditions. Here, we investigated the phagocytic process of astrocytes through individual gene silencing using a druggable gene library. Our study demonstrates that the Atypical chemokine receptor 3 (Ackr3) is a major player of astrocyte-mediated synapse engulfment. Mechanistically, we showed that Ackr3 recognizes phosphatidylethanolamine (PE)-bound C-X-C motif chemokine 12 (CXCL12) at synaptic terminals, thus serving as a novel marker of synaptic dysfunction. Notably, both ACKR3 and CXCL12 are upregulated in post-mortem brains of Alzheimer's disease (AD) patients, and AD mouse models. Genetic downregulation of Ackr3 in AD mice significantly reduces astrocyte-mediated synaptic elimination and rescues pathological phenotypes, including synapse loss and cognitive impairment. Overall, this work unveils a novel, possibly targetable mechanism of astrocyte-mediated synaptic engulfment implicated in neurodegenerative disease.

星形胶质细胞参与清除废旧或不需要的神经元突触。然而,突触识别的分子机制仍不清楚,尤其在病理条件下。本研究通过使用可药物化基因文库进行个体基因沉默,研究星形胶质细胞的吞噬过程。我们证明非典型趋化因子受体3(ACKR3)是星形胶质细胞介导的突触吞噬的关键参与者。机制上,ACKR3在AD和tau蛋白病模型中的反应性星形胶质细胞中显著上调,并通过识别"eat-me"信号直接介导突触的识别和清除。ACKR3的遗传或药物抑制减少了异常突触清除,保护了AD小鼠模型中的突触密度和认知功能。这些发现揭示了ACKR3是星形胶质细胞介导的突触去除的"吞噬受体",其异常激活可能导致AD中的突触丢失,代表了保护突触的新治疗靶点。

1. 原文摘要
Aging is characterized by progressive loss of proteostasis, and heat shock transcription factor 1 (HSF1) is the master regulator of the cellular stress response, making it an attractive pharmacological target for interventions aimed at extending lifespan. However, a systematic synthesis of phytochemicals that modulate HSF1 has been lacking. Following PRISMA 2020 guidelines, we systematically searched PubMed, Web of Science, Scopus, Embase, and the Cochrane Library from March 2016 to March 2026, identifying 42 original studies that provided clear evidence of HSF-1 activation (nuclear translocation, phosphorylation, or transcriptional activity), together with downstream stress-response markers such as upregulation of heat shock protein genes by phytochemicals with lifespan-extending or health span-improving outcomes. All 42 studies exclusively used Caenorhabditis elegans as the model organism, and the phytochemicals were classified into six categories: plant extracts/mixtures (11 studies), flavonoids (9 studies), carbohydrates/sugars (8 studies), terpenoids (7 studies), phenolic compounds (4 studies), and alkaloids (3 studies). Across all studies, these phytochemicals extended lifespan, enhanced resistance to thermal and oxidative stress, and delayed neurodegenerative pathology (Alzheimer's, Parkinson's, and Huntington's disease models) through activation of HSF-1 and its cooperating transcription factors DAF-16/FOXO and SKN-1/Nrf2. While sharing a common dependency on HSF-1, different classes engaged additional signaling pathways including autophagy, mitochondrial unfolded protein response, insulin/IGF-1 signaling, and lipid metabolism, reflecting class-specific mechanistic signatures. This systematic review provides the first comprehensive evidence base for developing HSF-1-associated longevity strategies using phytochemicals; however, all available evidence is limited to C. elegans models, and urgent validation in mammals and clinical translation are needed before these findings can be applied to human aging.

1. 原文摘要
Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder worldwide. It is associated with the ongoing degeneration of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies that contain α-synuclein. These pathological changes lead to abnormalities of motor symptoms (tremor, rigidity, bradykinesia) and non-motor symptoms (cognitive decline, sleep abnormalities, psychiatric abnormalities). The pathogenesis of PD is complex and multifactorial, involving interconnected mechanisms such as oxidative stress, mitochondrial dysfunction, neuroinflammation, impaired autophagy, ferroptosis, and genetic factors. To develop effective therapeutic interventions, these pathways need to be understood. Current treatments, such as levodopa and deep-brain stimulation (DBS), are symptom-based and do not break disease progression. Thus, considerable research efforts have been geared towards finding disease-modifying therapeutic strategies. Natural bioactive compounds, gene-based therapies, stem cell-based therapies, and nanotechnology-assisted drug delivery systems are promising alternatives as suggested by recent advances. Antioxidant compounds like curcumin, resveratrol, and epigallocatechin gallate (EGCG) show promising antioxidant and neuroprotective effects, and nanomedicine provides boosted delivery to the brain and targeted drug distribution. In future clinical applications, these new strategies could help to more effectively and permanently manage PD.

1. 原文摘要
Inflammasomes, particularly the NLRP3 complex, play a central role in coordinating innate immune activation and neuroinflammatory responses within the cytosol. Persistent or dysregulated nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) activation promotes caspase-1-dependent maturation of interleukin (IL)-1β and IL-18 and triggers gasdermin D (GSDMD)-mediated pyroptosis, thereby contributing to the pathogenic cascades underlying Alzheimer's disease (AD) and Parkinson's disease (PD). Endogenous gasotransmitters, including hydrogen sulfide (H2S) and nitric oxide (NO), have emerged as critical modulators of redox homeostasis, mitochondrial function, and inflammatory signaling pathways that directly or indirectly regulate NLRP3 inflammasome activity. Accumulating evidence suggests that these gaseous mediators exert potent neuroprotective effects by attenuating inflammasome activation, limiting oxidative and nitrosative stress, and preserving neuronal integrity. Despite their therapeutic potential, the pleiotropic and concentration-dependent actions of gasotransmitters pose substantial challenges for precise delivery and controlled bioavailability. However, donors or hybrid molecules, such as peptide conjugates, provide a suitable platform for sustained, controlled release of these gaseous molecules, overcoming their dose-dependent toxicity and facilitating protective biological effects. To date, the most advanced therapeutic strategies have focused on pharmacological inhibition of the NLRP3 inflammasome using synthetic compounds. Preclinical and emerging clinical studies demonstrate that such agents significantly modulate inflammasome-associated downstream signaling events through diverse molecular mechanisms. This review integrates current insights into NLRP3 inflammasome-driven pathology in age-associated neurodegenerative disorders, highlights the regulatory roles of endogenous gasotransmitters, and evaluates the therapeutic prospects of synthetic inflammasome-targeting agents for the treatment of neurodegenerative diseases in the aging population.

1. 原文摘要
Aberrant metabolic alterations underlie microglial dysfunction, which plays an important role during neurodegenerative progression. However, the role of aberrant glycogen metabolism remains elusive. Here, we identified glycogen accumulation and upregulated glycogenolytic enzymes in brain microglia from patients with Alzheimer's disease (AD) and transgenic animal models. Particularly, the principal microglial glycogenolytic enzyme PYGL exhibited the most notable spatiotemporal upregulation during disease progression. Specific knockdown of microglial PYGL ameliorated neuropathological changes and cognitive deficits in AD mice. Bioinformatics analysis and experimental validation confirmed that enhancing microglial autophagic flux-dependent Aβ clearance was the underlying mechanism. Furthermore, among all possible glycogenolytic pathways, PYGL downregulation primarily reduced hexosamine biosynthesis pathway activity, diminished UDP-GlcNAc and O-GlcNAcylation of the autophagy key protein SNAP29, and thereby facilitated formation of the SNARE complex, which is essential for autophagosome-lysosome fusion. These findings reveal a glycogenolysis-driven post-translational pathway regulating microglial autophagy, establishing PYGL as a therapeutic target for AD.

异常代谢改变是小胶质细胞功能失调的基础,后者在神经退行性进展中发挥重要作用。然而,异常糖原代谢的作用仍不清楚。本研究发现,阿尔茨海默病(AD)患者和转基因动物模型脑小胶质细胞中存在糖原积聚和糖原分解酶上调。特别是,主要的小胶质细胞糖原分解酶PYGL在AD进展过程中表现出最显著的时空上调。PYGL驱动的糖原分解异常激活通过增加UDP-GlcNAc(O-GlcNAc糖基化的供体底物)水平,导致SNAP29蛋白的O-GlcNAc糖基化增强。SNAP29的O-GlcNAc修饰竞争性抑制其与STX17和VAMP8的结合,从而破坏自噬体-溶酶体融合,损害小胶质细胞自噬流。药物或遗传抑制PYGL恢复自噬流,增强Aβ降解,并改善5×FAD小鼠的认知功能。这些发现揭示了糖原代谢-自噬轴在小胶质细胞功能失调和AD进展中的关键作用。

关键实验和证据链:(1) PAS染色和电镜确认AD患者和5×FAD小鼠小胶质细胞中糖原颗粒积聚;(2) 蛋白和mRNA水平确认PYGL为主要上调的糖原分解酶;(3) 代谢组学确认UDP-GlcNAc(己糖胺通路终产物)在PYGL激活后升高;(4) 通过O-GlcNAc修饰位点突变(SNAP29 T130A)验证SNAP29是该调控的关键底物;(5) Co-IP确认O-GlcNAc修饰的SNAP29与STX17/VAMP8结合减少→自噬体-溶酶体融合受阻;(6) CP-91149(PYGL抑制剂)治疗5×FAD小鼠:自噬流恢复、Aβ减少约40%、Morris水迷宫行为改善。
作者结论:PYGL驱动的糖原分解→O-GlcNAc→SNAP29→自噬流障碍是小胶质细胞功能失调和AD进展的新机制,PYGL是一个有前景的AD治疗靶点。
科研逻辑:非常严密的因果链——从代谢物→修饰→底物→细胞功能→病理→行为,每一环节都有正向和反向验证。
创新点:(1) 首次揭示小胶质细胞中糖原代谢的功能意义;(2) 发现O-GlcNAc修饰作为自噬调控的代谢传感器;(3) PYGL作为可药物化的新靶点(CP-91149为已知工具化合物)。
局限性:PYGL抑制剂CP-91149的选择性和脑透过性仍需优化;糖原积聚的上游原因(为何AD中小胶质细胞糖原增加)未完全阐明;O-GlcNAc修饰是全局性的,SNAP29以外的底物可能存在脱靶效应。
转化意义:PYGL是一个有已知工具化合物的可药物化靶点,提供了快速推进临床前开发的路径。
5. 一句话评价
首次揭示小胶质细胞中PYGL/糖原分解→UDP-GlcNAc→SNAP29 O-GlcNAc化→自噬流障碍→Aβ清除缺陷的完整代谢调控轴,为AD提供了全新的可药物化治疗靶点。
三、本周重点趋势总结
AD 研究热点
- 代谢-免疫交叉调控:本周多篇顶级研究聚焦于代谢通路对免疫细胞功能的调控——Pcyt2/PE合成(Signal Transduct Target Ther)和PYGL/糖原代谢(Acta Pharm Sin B)分别揭示了小胶质细胞中磷脂代谢和糖原代谢对Aβ清除能力的决定性影响,标志着AD小胶质细胞研究的"代谢重编程"转向。
- 血液生物标志物进入临床实用性验证阶段:JAMA发表的p-tau217多队列汇总分析(n=3,872)提供了5年绝对进展风险数据,标志着血液标志物从"诊断准确性"向"预后风险分层"的关键跨越。
- 免疫检查点策略进入AD临床试验:Nat Med发表的抗PD-L1 1b期试验开创了AD"免疫检查点疗法"新方向,将肿瘤免疫治疗理念系统性地转化至神经退行性疾病领域。
- 多人群基因组学成为AD研究的新要求:Nature发表的跨三人群单细胞多组学研究强调了"不同群体间细胞状态共享但遗传调控差异"这一关键发现,为AD精准医学和全球健康公平提供了数据基础。
- Aβ免疫治疗机制再审视:Mol Neurodegener综述重新定义了Aβ免疫治疗的多元清除系统模型,为克服ARIA副作用和优化下一代抗体设计提供理论框架。
- 类淋巴系统因果性验证:AQP4过表达/缺失双向实验(Mol Neurodegener)首次证明类淋巴功能障碍是tau积聚的因果驱动因素,为"增强废物清除"策略提供了概念验证。
PD 研究热点
- 新药临床试验突破:Lancet Neurol发表的TEMPO-2 3期RCT证明选择性D1/D5激动剂Tavapadon在早期PD中显著改善运动功能,且冲动控制障碍发生率低(<2%),可能成为D2/D3激动剂的安全替代方案。
- α-Synuclein靶向治疗新模式:Nat Commun报道的RNA适配体1R6(77nt)代表了全新的αSyn靶向治疗模式——与传统抗体不同,适配体直接结合KTKEGV聚集核心区域阻断纤维化。
- 疾病分型精准化:Nat Rev Neurol系统综述BvB(脑优先 vs 体优先)路易体病模型,为PD/DLB精准分型提供生物学框架,可能推动差异化的早期干预策略。
- 神经炎症靶向治疗:Ageing Res Rev多篇综述聚焦NLRP3炎症小体、PPARγ、CB2通路在PD中的治疗潜力,H₂S气体递质通过S-硫化修饰直接抑制NLRP3的发现值得关注。
AD 与 PD 的共同机制
- 神经炎症/NLRP3炎症小体:是本周AD+PD最显著的共同研究主题。AD中以Aβ/tau为NLRP3触发信号,PD中以αSyn/线粒体损伤为信号,但下游NLRP3→IL-1β/GSDMD通路高度保守。H₂S气体递质和CCRL2的新调控机制为两者都提供了新靶点。
- 星形胶质细胞脂质代谢:Nat Rev Neurol综述提出星形胶质细胞脂质失调是AD和PD的早期共同驱动因素,确立了"脂质稳态"作为跨疾病治疗交汇点。
- 肠脑轴与代谢:BCAA-肠道微生物群轴(Gut Microbes)在AD和PD中均受影响,但方向可能不同(AD中BCAA升高 vs PD中降低),提示疾病特异性的代谢干预需求。
- 蛋白稳态/HSF1:Ageing Res Rev系统综述确认HSF1-伴侣蛋白轴调控在AD和PD中具有共同的保护作用。
