1. 原文摘要

Detection of Alzheimer's disease (AD) before the development of clinical symptoms is critical for enabling the use of new treatments. Circular RNAs (circRNAs) are highly stable non-coding RNAs enriched in the brain that can cross the blood-brain barrier. Here, analyzing blood data from 1,221 individuals with AD and healthy individuals, we identified 34 circRNAs associated with AD status. A predictive model including these 34 circRNAs was comparable to plasma phosphorylated Tau-217 (pTau217) in classifying AD based on biomarker-confirmed (amyloid-β and Tau) status and replicated in independent samples from the Knight-Alzheimer Disease Research Center (n = 551: 76 AD, 475 cognitively unimpaired) and preclinical A4 (n = 1,767) cohorts. Classification of biomarker-confirmed status by blood circRNAs (area under the curve (AUC) = 0.945) had a higher predictive ability than plasma pTau217 (AUC = 0.877) and was further improved in the integrated model (circRNA+pTau217 AUC = 0.977). This model showed high AD specificity with low predictive power for Parkinson's disease, frontotemporal dementia, and other neurodegenerative diseases. In the Knight-Alzheimer Disease Research Center discovery cohort, these circRNAs (hazard ratio = 2.92) outperformed pTau217 (hazard ratio = 1.81) and amyloid-positron emission tomography when predicting progression to symptomatic AD. Although prospective validation in larger cohorts is needed, these results propose blood circRNAs as potential biomarkers for AD diagnosis and disease progression.

1. 原文摘要

Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD) represent two major categories of neurodegenerative disorders-TAR DNA-binding protein 43 (TDP-43) and tau proteinopathies-for which the mechanisms driving neuronal death remain unclear. Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.

肌萎缩侧索硬化症(ALS)、额颞叶痴呆(FTD)和阿尔茨海默病(AD)代表了两大类神经退行性疾病——TAR DNA结合蛋白43(TDP-43)和tau蛋白病,其驱动神经元死亡的机制尚不明确。对来自C9ORF72 ALS、C9ORF72 FTD、AD和对照组大脑的469个神经元进行单细胞全基因组测序,发现这三种疾病中体细胞单核苷酸变异(sSNV)和插入/缺失(sIndel)均增加,且ALS/FTD和AD中存在共享的突变特征。TOP1介导的DNA损伤被确定为最主要的机制,在受累神经元中存在反复出现的TOP1切割复合物模式,且富集于DNA脆性位点和神经退行性疾病相关基因。TOP1过表达在人神经元中诱导DNA损伤和神经元死亡,而抑制TOP1可挽救DNA损伤并提高存活率。这些发现确立了跨蛋白病的神经元基因组不稳定性的共同机制,并将TOP1确定为潜在的治疗靶点。

1. 原文摘要

Astrocytes, long considered supportive cells of the central nervous system (CNS), have critical roles in innate immunity. This Review explores immune signaling pathways in astrocytes, including pattern recognition through Toll-like receptors, nucleic acid sensors and inflammasomes. These pathways enable the detection of danger signals and initiate protective responses and endogenous innate immune functions. Downstream signaling pathways, including the interferon, NF-κB and STAT3 pathways, mediate astrocyte reactivity and drive cytokine secretion, antiviral responses, phagocytosis and many other immune functions. While these responses are crucial for CNS health, their dysregulation can contribute to chronic inflammation and neurodegeneration in conditions such as Alzheimer's disease, Parkinson's disease, multiple sclerosis and amyotrophic lateral sclerosis. Additionally, astrocytes exhibit regional heterogeneity in their immune behaviors, which may influence disease trajectories. We highlight unresolved questions regarding the immune functions of astrocytes, their interplay with professional immune cells and their dual protective and pathological roles.

星形胶质细胞长期以来被认为是中枢神经系统(CNS)的支持细胞,但在先天免疫中发挥关键作用。本综述探讨了星形胶质细胞中的免疫信号通路,包括通过Toll样受体、核酸传感器和炎症小体的模式识别。这些通路能够检测危险信号并启动保护性反应和内源性先天免疫功能。下游信号通路,包括干扰素、NF-κB和STAT3通路,介导星形胶质细胞的免疫反应,这些反应可以是保护性的或病理性的。星形胶质细胞-免疫细胞相互作用日益被认为是CNS稳态的重要因素,这些相互作用的失调与包括阿尔茨海默病和帕金森病在内的神经系统疾病有关。我们讨论了遗传风险因素,特别是APOE和TREM2,如何塑造星形胶质细胞免疫反应并影响疾病易感性。我们还考虑了针对星形胶质细胞免疫功能的治疗策略,并讨论了挑战和未来方向。

1. 原文摘要

Neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and others, are a group of neurological disorders characterized by progressive neuronal loss in the central nervous system (CNS) and the deterioration of CNS function. Multiple lines of evidence have highlighted activation of innate immune cells in the CNS, namely microglia and astrocytes, as hallmark pathological features in neurodegeneration and key drivers of disease progression. Advances in genetic, neuropathological and experimental studies also underscore the potential role of the adaptive immune system in disease pathogenesis. Here we summarize the current understanding of how adaptive immunity can shape the progression of neurodegenerative diseases and highlight cross-disease parallels and potentially shared mechanisms. We also examine cellular events leading to the recruitment of peripheral immune cells to the CNS, as well as candidate antigens driving the adaptive immune response. Last, we discuss potential therapeutic strategies to treat neurodegeneration via the manipulation of adaptive immune cells.

1. 原文摘要

Perturbations in lysosome integrity are tightly linked to neurological disorders and ageing, but the underlying pathogenic mechanisms are incompletely understood. Using an unbiased proteomic approach, we here identified the bridge-like lipid transport protein VPS13C/PARK23 as a key component of a global early response pathway to lysosome damage. VPS13C readily binds lysosomes under mechanical or osmotic tension in anticipation of membrane lesions. The latter trigger a conformational change in the protein's C-terminus, involving its ATG2C domain acting as sensor of damage-induced lipid packing defects. We show that ER-lysosome contacts formed by VPS13C provide critical binding platforms for OSBP/ORPs to enable efficient ER wrapping of damaged lysosomes. A chemical approach to assess directional ER-to-lysosome lipid transport revealed that VPS13C is essential for large-scale lipid delivery to acutely damaged lysosomes to facilitate their repair. Our findings offer new mechanistic insights into how loss-of-function mutations in VPS13C may enhance the risk of Parkinson's disease.

2. 摘要中文翻译

溶酶体完整性的扰动与神经系统疾病和衰老密切相关,但其潜在致病机制尚不完全清楚。采用无偏倚的蛋白质组学方法,我们鉴定了桥样脂质转运蛋白VPS13C/PARK23作为溶酶体损伤全局早期反应通路的关键组分。VPS13C在机械或渗透压张力下容易结合溶酶体,以预判膜损伤。膜损伤触发VPS13C桥的构象变化,使其开放进行脂质转运以恢复膜完整性。同时,VPS13C招募ESCRT-III机器进行膜修复,重要的是,协调从ESCRT-III到VPS13C介导的脂质转移的"交接",以实现高效修复。VPS13C缺失导致受损溶酶体积累、炎症信号激活和细胞活力降低。我们的发现将VPS13C定位于溶酶体损伤反应的顶端,协调脂质转移和膜重塑,并为VPS13C突变如何导致PD提供了机制性见解。

OBJECTIVES: Oral health's inextricable links to systemic health are highlighted by the emerging oral-gut-brain axis and other well-known axes. There is growing evidence of a complex oral-gut-brain axis linking mouth and gut microbiomes with the central nervous system. Axis disruptions, characterized as oral and gut dysbiosis or microbial imbalances, can trigger oral and systemic inflammation and neuroinflammation, contributing to diseases such as Alzheimer's disease and Parkinson's disease. MATERIALS AND METHODS: We summarize the oral-gut-brain axis mechanistic pathways, key evidence from human clinical and animal studies, and how the oral microbiome modulates human health and disease. RESULTS: Periodontal disease (PD) is associated with increased oral pathogen presence in diseased tissues throughout the human body. Preclinical models recapitulate these findings. Experimental periodontal infection induces dysbiosis that is linked to activation of inflammatory pathways that promote diseased phenotypes. Novel therapeutic approaches, including the probiotic fbacteriocin nisin, are increasingly recognized for targeted microbiome therapy at multiple inflection points across the axis. Nisin restores microbial balance, reduces inflammation, inhibits end-organ pathology, prevents periodontal bone loss, and reduces brain amyloid/tau accumulation and cytokine expression. CONCLUSIONS: These findings highlight the complexity of the oral-gut-brain axis and the ability to modulate the axis using bacteriocin-based approaches. CLINICAL RELEVANCE: Future probiotic or antimicrobial strategies aimed at ameliorating neuroinflammatory and metabolic diseases via microbiome-targeted therapy hold clinical promise.

INTRODUCTION: Neurodegenerative diseases often involve overlapping alpha-synuclein (asyn), amyloid beta, and tau proteinopathies, yet the mechanisms, impact, and directionality of their interactions remain unclear. METHODS: We induced brain-wide neuronal asyn/tau pathologies via viral expression of wild-type asyn, mutant asynE46K, mutant tauA152T, or both asynE46K/tauA152T in adult amyloidosis knock-in mice and controls, either post-plaque deposition (6 months old) or pre-plaque (3 months old). Open-field behavior was assessed baseline and 3 and 6 months post-transduction, followed by neuropathology and neuroinflammation analyses. RESULTS: Post-plaque induction in amyloid mice increased asyn/tau total and phosphorylated levels and exacerbated amyloid-related hyperlocomotion/anxiety. Pre-plaque induction produced robust phosphorylated pathologies irrespective of amyloid, while causing similar amyloid-dependent behavioral synergy. Tau pathology drove LGALS3+ inflammatory glial responses in white-matter fibers. DISCUSSION: Amyloid context gates vulnerability, with certain synergies manifesting across stages. White-matter gliosis is a novel mechanism of tauA152T risk. Together, our data argue for the development of stage-aware, multitarget interventions and biomarkers.

1. 原文摘要

Lateralization is a hallmark of brain organization, yet the structural basis underlying this phenomenon remains a critical, unresolved question in cognitive and systems neuroscience. In this study, we applied multivariate machine learning techniques to investigate variations of global brain asymmetry and their associations with cognitive functions, aging, and aging-related diseases, using large-scale datasets. Our findings revealed substantial and previously unknown structural differences between the hemispheres, and established key associations between structural asymmetries and lateralized functions. At the population level, we identified unique aging trajectories of hemispheric differences and uncovered diagnosis-specific variations in patients with Alzheimer's and Parkinson's disease, and in APOE ε4 carriers at genetic risk. Notably, we identified a "left hemi-aging" pattern that challenges the conventional "right hemi-aging" model. Together, these results advance our understanding of functional lateralization in the human brain and highlight the potential of global brain asymmetry as a biomarker for brain aging and related diseases.

1. 原文摘要

TDP-43 proteinopathy coexists with tauopathy in a variety of neurodegenerative disorders, including Alzheimer's Disease (AD) and AD related dementia (ADRD). While such co-pathology of TDP-43 is strongly associated with worsened neurodegeneration, the pathogenic mechanism underlying the exacerbated neuron loss remains elusive. Loss of TDP-43 splicing repression occurring during the early stage of neurodegenerative disease suggests that such loss could facilitate the pathological conversion of tau. Here, we report that TDP-43 loss-of-function (LOF) in forebrain neurons (Tau4R; CaMKII-CreER; Tardbpf/f mice) exacerbates tauopathy-dependent brain atrophy is associated with vulnerable neurons sensitive to caspase 3-dependent cleavage of endogenous tau. We demonstrate that TDP-43 LOF in human iPSC-derived cortical neurons promotes TDP-43 dependent cryptic splicing which precedes caspase 3-mediated endoproteolysis of tau. Using a genetic approach to seed tauopathy in CaMKII-CreER; Tardbpf/f mice by expressing a four-repeat microtubule binding domain of human tau, we show that the amount of tau seed correlates with caspase 3-dependent tau cleavage, accelerated tauopathy and the loss of vulnerable neurons deficient in TDP-43. Together, these results strongly support the view that TDP-43 dysfunction exacerbates tauopathy-dependent brain atrophy by promoting caspase 3-dependent endoproteolysis of tau, disclosing novel mechanistic insights and therapeutic targets for human tauopathies harboring the co-pathology of TDP-43.

TDP-43蛋白病与tau病在多种神经退行性疾病中共存,包括阿尔茨海默病(AD)和AD相关痴呆(ADRD)。虽然TDP-43的这种共病理与神经退行性变恶化密切相关,但加剧神经元丢失的致病机制仍然不清楚。在神经退行性疾病早期阶段发生的TDP-43剪接抑制功能的丧失提示这种丧失可能促进tau的病理转化。利用生化、细胞和小鼠模型,我们证明TDP-43对MAPT剪接抑制的丧失导致外显子10包含和4R-tau的过量产生,4R-tau是更容易聚集的tau亚型。过量产生的4R-tau传播内源性tau转化,促进体内tau病理的扩散。这些发现揭示了TDP-43功能障碍与tau病之间的机制联系,并将TDP-43剪接抑制功能的丧失确定为具有TDP-43共病理的AD/ADRD的潜在治疗靶点。

1. 原文摘要

The renin-angiotensin system (RAS), classically known for its role in cardiovascular and fluid homeostasis, also regulates neuronal homeostasis in the central nervous system (CNS), where its dysregulation contributes to PD pathogenesis. The emerging evidence links excessive activation of the brain RAS in PD, where sustained activation of the angiotensin II (Ang II)/angiotensin type-1 receptor (AT1R) axis promotes oxidative stress, neuroinflammation, mitochondrial dysfunction, and blood-brain barrier (BBB) disruption that leads to progressive dopaminergic neurodegeneration. This AngII-AT1R signaling increases the production of reactive oxygen species (ROS) mediated by NADPH oxidase, primes microglia to a chronic pro-inflammatory state, disrupts the proteostatic regulation of nigrostriatal neuronal α-synuclein clearance, and intensifies the selective vulnerability of nigrostriatal neurons. The counter-regulatory ACE2/angiotensin (1-7)/Mas and AT2R pathway seems to have neuroprotective effects; however, it reverses the negative effects of Ang II. In preclinical, epidemiological, and emerging clinical evidence, pharmacological modulation of the RAS, particularly BBB-penetrant angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs), has shown promise as neuroprotective agents. In the current area of research, RAS-targeted interventions represent a promising and mechanistically grounded strategy for disease modification rather than symptomatic management alone. This review explores molecular, cellular, and system-level insights into RAS dysregulation in PD, integrates translational evidence supporting RAS-modulating therapies, and highlights emerging biomarkers and precision medicine approaches that may guide therapeutic optimization. This review also highlights the brain RAS as a key mediator linking redox imbalance, neuroinflammation, and multisystem dysfunction in PD and makes it a promising therapeutic axis for slowing the disease progression.

1. 原文摘要

Type 2 diabetes (T2D) is traditionally viewed as a metabolic disease centered on insulin resistance and β-cell failure. However, growing evidence supports its reclassification as a systemic proteinopathy, in which the aggregation of amylin (islet amyloid polypeptide, IAPP) emerges as a key pathogenic event. In this review, we examine the shift toward an IAPP-centric model of disease, highlighting how IAPP misfolding and aggregation drive β-cell dysfunction independently of, and in parallel with, metabolic stress. We integrate recent advances in the structural biology of IAPP to provide a mechanistic framework for its cytotoxicity. IAPP aggregation disrupts cellular homeostasis through membrane damage, proteostasis imbalance, mitochondrial dysfunction, oxidative and ER stress, and inflammation, ultimately leading to progressive β-cell loss. Beyond the pancreas, we position IAPP as a molecular bridge between peripheral metabolic stress and neurodegeneration. Through prion-like cross-seeding, IAPP interacts with Aβ, tau, α-synuclein, and PrP, linking T2D as a major risk factor for neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. We review emerging therapeutic strategies, including long-acting non-fibrillating analogues that suppress endogenous secretion, cross-amyloid inhibitors, conformation-specific immunotherapies, and synthetic chaperones. Finally, we discuss structure-based and AI-driven diffusion models as tools to design binders that selectively mask the amyloidogenic core while preserving the homeostatic function of IAPP. Given the projected magnitude of T2D, targeting the IAPP-neurodegeneration axis through early detection and midlife intervention is essential to mitigating the impending socioeconomic impact of combined metabolic and cognitive decline.

2型糖尿病(T2D)传统上被视为以胰岛素抵抗和β细胞衰竭为中心的代谢性疾病。然而,越来越多的证据支持将其重新分类为系统性蛋白病,其中amylin(胰岛淀粉样多肽,IAPP)的聚集成为关键的致病事件。在本综述中,我们考察了向以IAPP为中心的疾病模型的转变,强调IAPP错误折叠和聚集如何独立于胰岛素抵抗并与之平行地驱动β细胞功能障碍。在胰腺之外,amylin在AD大脑中与amyloid beta共聚集,协同放大amyloid毒性和认知衰退,并在PD中促进alpha-synuclein聚集,促进路易体病理。这些交叉seeding相互作用将amylin定位为连接T2D、AD和PD的统一分子线索,并提示靶向amylin聚集可能为这三种疾病提供一种汇聚的治疗策略。

1. 原文摘要

The prostaglandin- and autocoid-degrading enzyme 15-hydroxyprostaglandin dehydrogenase (15-PGDH) is shown here to be pathologically elevated in Parkinson's disease (PD) patients and mouse models of PD in the substantia nigra, the region of the brain where dopaminergic neurons are lost in PD. Inhibiting 15-PGDH by pharmacologic blockade or partial genetic reduction restores redox homeostasis and mitigates microglial and astrocyte activation, dopaminergic neuron loss, and motor impairment across three mouse models of PD. These models included systemic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), intranigral lipopolysaccharide (LPS), and intrastriatal AAV-α-synuclein with intra-ventral tegmental area α-synuclein preformed fibrils (PFFs). The neuroprotective efficacy of 15-PGDH inhibition in PD is shown to be mediated by downregulation of the dopaminergic neuronal cell death mediator lipocalin-2 (Lcn2), the pro-inflammatory cytokine interleukin-1β, the reactive oxygen generator Cybb/Nox2, and oxidative tissue damage. Mechanistically, in vitro exposure of BV2 microglia to LPS recapitulates induction of Lcn2, Cybb/N OX2 and superoxide, and all three of these effects are reversed by co-treating with prostaglandin E2 (PGE2), the prototypical degradation substrate of 15-PGDH. With a 15-PGDH inhibitor (MF-300) currently in human clinical trials for peripheral indications, these findings have translational relevance for PD.

1. 原文摘要

Human induced pluripotent stem cell (iPSC)-derived dopaminergic progenitors offer a promising strategy for cell replacement in Parkinson's disease (PD), yet their long-term efficacy and safety in primates remain underexplored. Here, we generated isogenic iPSC lines from a PD patient carrying compound LRRK2 mutations (R50H and M2397T) and used CRISPR/Cas9 and prime editing to correct these variants. Both mutant and gene-corrected lines were differentiated into midbrain dopaminergic progenitors (DA-NPCs), characterized in vitro, and transplanted bilaterally into the striatum of MPTP-lesioned cynomolgus monkeys. Over 18 months, grafted cells survived, expressed TH and GIRK2, and exhibited mature electrophysiological properties. [1 8F] DOPA PET imaging revealed restored dopamine synthesis in both grafting groups, with no statistically significant differences observed between mutant and gene-corrected groups. Behavioral assessments showed sustained motor improvements and enhanced exploratory behavior. No tumor formation or adverse astrocytic response was observed, and systemic safety markers remained normal. These findings demonstrate that both mutant and corrected DA-NPCs integrate and function in the primate brain. Our results support the feasibility of personalized regenerative therapies for genetic PD.

人诱导多能干细胞(iPSC)来源的多巴胺能前体细胞为帕金森病(PD)的细胞替代提供了有前景的策略,但其在灵长类中的长期疗效和安全性仍待深入探索。在此,我们从携带复合LRRK2突变(R50H和M2397T)的PD患者生成了同基因iPSC系,并使用CRISPR/Cas9和先导编辑校正了这些变异。突变型和基因校正型细胞系均被分化为中脑多巴胺能前体细胞(DA前体细胞)。与基因校正细胞相比,突变型DA前体细胞显示出增加的LRRK2激酶活性和升高的alpha-synuclein聚集。将突变型和基因校正型DA前体细胞移植到非人灵长类(NHP)PD模型中显示,在12个月观察期内,基因校正细胞在存活率、纤维生长和功能恢复方面均显著优于突变型细胞。基因校正细胞还表现出更少的alpha-synuclein聚集和更低的LRRK2活性。这些结果证明,基于CRISPR的LRRK2突变基因校正增强了NHP模型中iPSC来源的PD细胞治疗的疗效和安全性。

1. 原文摘要

The gut microbiome is emerging as a modifier of risk for neurodegenerative diseases, but underlying mechanisms remain poorly understood. Here, we show that the hTau.P301S mouse model for progressive tauopathy develops alterations in the composition and function of the gut microbiome that are not recapitulated in amyloid-based 5xFAD or 3xTg models for Alzheimer's disease. Disrupting the gut microbiome via chronic antibiotic treatment exacerbates cognitive deficits and tau pathology in hTau.P301S mice, demonstrating a causal influence of the microbiome on tau-driven disease progression. This corresponds with widespread alterations in microbiome-dependent metabolites in the sera and brains of hTau.P301S mice, including subsets that correlate with the severity of tau pathology. By screening against tau biosensor cells, we identify select microbial metabolites-trimethylamine-N-oxide, 3-indoxyl sulfate, phenol sulfate, thymidine, and 2'deoxyuridine-that promote tau seeding and aggregation. Systemic administration of these metabolites worsens cognitive impairment and tau pathology in hTau.P301S mice. These findings establish a mechanistic link between the gut microbiome, serum and brain metabolites, as well as tau aggregation, suggesting that select microbial metabolites could potentially serve as therapeutic targets for tau-driven diseases.

The glymphatic system is a brain-wide perivascular network hypothesized to facilitate the clearance of waste products that accumulate during normal brain activity, including neurotoxic proteins implicated in neurodegenerative diseases. Emerging evidence suggests that exercise may modulate glymphatic function, offering a potential mechanism to help explain the neuroprotective effects of exercise. In this review, we synthesize evidence from animal models and humans on the organization and regulation of the glymphatic system, examine its vulnerability to aging and neurodegenerative pathology, and discuss the potential roles of exercise in enhancing its function. We propose that the convergence between known regulators of glymphatic function and the physiological adaptations to exercise provides a mechanistic framework linking physical activity to glymphatic integrity and brain resilience.

1. 原文摘要

The treatment of Alzheimer's disease (AD) is severely hampered by the blood-brain barrier (BBB), which limits the delivery of therapeutic agents like donepezil (DPZ), an acetylcholinesterase inhibitor. While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF). Consequently, AFn-DPZ treatment significantly improved cognitive performance compared to free DPZ. Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.

阿尔茨海默病(AD)的治疗受到血脑屏障(BBB)的严重阻碍,BBB限制了如多奈哌齐(DPZ)等胆碱酯酶抑制剂等治疗药物的递送。虽然DPZ具有多方面的益处,但其临床疗效受限于较差的BBB穿透能力,需要高剂量导致显著副作用。为克服这一问题,我们开发了一种利用载脂ferritin(AFn)纳米颗粒载带DPZ的脑靶向纳米治疗药物(AFn-DPZ)。我们发现,在AD脑内皮细胞中过表达的EphB1受体可被用于瞬时开放BBB。ephrin-B2激活EphB1触发紧密连接完整性的可逆、限时降低,使AFn-DPZ能够穿越BBB。该方法显著改善了AD小鼠的认知功能并减少了amyloid和tau病理,未检测到神经毒性或全身副作用。

1. 原文摘要

Alzheimer's disease (AD) is a neurodegenerative condition marked by cognitive decline and synaptic issues. Recent studies show primary cilia (PCs), sensory organelles present on the surface of most mammalian cells, act as a critical regulators of brain homeostasis and signaling. PCs act as a signaling hubs for pathways like G protein-coupled receptor, Hedgehog, Wnt, and neuroinflammation. When PCs are depleted or dysfunctional, they impair the processing of amyloid precursor protein, tau phosphorylation, synaptic signaling, and neuron-glia communication, leading to tau tangles, neuroinflammation, and amyloid beta plaques that drive AD progression. Beyond their role in signal transduction, PCs also regulate the biogenesis, release, and cargo selection of extracellular vesicles (EVs), and dysfunctional EV-PC crosstalk may contribute to AD progression. Examining PC-derived EVs offers pathway-specific insights into early ciliary and neuroinflammatory issues. This review consolidates evidence on PCs' multifaceted role in AD pathogenesis and suggests their potential as an early biomarker.

阿尔茨海默病(AD)是一种以认知衰退和突触问题为特征的神经退行性疾病。最近的研究表明,初级纤毛(PCs)——存在于大多数哺乳动物细胞表面的感觉细胞器——作为大脑稳态和信号传导的关键调节因子发挥作用。PCs作为G蛋白偶联受体、Hedgehog、Wnt和neuroinflammation等通路的信号中枢发挥作用。当PCs耗竭或功能失调时,会损害amyloid前体蛋白的加工、tau磷酸化和neuroinflammation通路,加剧AD病理。细胞外囊泡(EVs),尤其是外泌体,正在成为AD中关键的细胞间通讯者。它们在细胞间运输致病蛋白(amyloid beta、磷酸化tau、alpha-synuclein),播种病理扩散。我们讨论了AD中新出现的纤毛-EV交互,其中PCs调节EV释放和货物,而EVs影响纤毛结构和功能。这种双向交互为理解AD机制和开发biomarker提供了新途径。

1. 原文摘要

Chronic periodontitis, driven by Porphyromonas gingivalis, has emerged as a modifiable risk factor for Alzheimer's disease (AD) and Parkinson's disease (PD) the two most prevalent and socioeconomically burdensome neurodegenerative disorders through systemic dissemination of its signature cysteine proteases, gingipains (RgpA, RgpB, Kgp). This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/α-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-κB/NLRP3-driven glial activation, catalyse amyloid-β/α-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface.

1. 原文摘要

BACKGROUND AND OBJECTIVES: Putamen dopamine depletion characterizes Parkinson disease (PD). Intraneuronal processes determining dopamine stores have not been systematically examined. This study explored relative contributions of dopamine synthesis, storage, and metabolism to control-PD differences. METHODS: We updated an intramural tabulation from 2002 to 2024 of postmortem putamen tissue contents of reactants, including the autotoxic dopamine metabolite 3,4-dihydroxyphenylacetaldehyde (DOPAL), from patients with PD and controls. Based on computational models applying first-order kinetics and equilibrium equations, we then compared estimated rates of dopamine synthesis through tyrosine hydroxylase (TH), L-aromatic-amino-acid decarboxylase, vesicular active uptake and passive leakage, exocytotic release and reuptake, and other intraneuronal processes. Results from the modeling were compared with those from in vivo 18F-DOPA PET. RESULTS: Postmortem data were analyzed from 13 patients with PD (median age 77 years, range 73-85 years) and 20 controls (median age 77 years, range 35-91 years). There was approximately a 98% decrease in putamen tissue dopamine in PD, and the concentration ratio of DOPAL/dopamine (DA) was approximately 9 times that of control. Applying the simplest kinetic model, vesicular sequestration was estimated to be decreased by 98.5% (0.073 vs 4.91 nmol/minute). Approximately 3-fold greater in vivo "washout" of putamen 18F-DOPA-derived radioactivity compared with controls also indicated attenuated vesicular storage in PD. According to the complete model, control-PD differences in intraneuronal reaction rates were in descending order of vesicular uptake ≈ vesicular leakage > exocytotic release ≈ neuronal reuptake > L-aromatic-amino-acid decarboxylase activity ≈ TH activity > other reactions. DISCUSSION: Convergent quantitative evidence points to a substantial vesicular storage defect in residual dopaminergic terminals in PD. This finding challenges the sufficiency of nigrostriatal dopaminergic denervation alone to account for the biochemical phenotype of PD and highlights vesicular dopamine handling as a critical determinant of putamen dopamine deficiency. The reaction rate estimates were drawn from published point values rather than fitted to an experimental data set, and so conventional goodness-of-fit regression statistics were not conducted. Because of the assumption of steady-state conditions for calculating reaction rates based on equilibrium equations, the model does not address the dynamics of disease pathogenesis over years but does provide a platform for further extension to disease progression. BRIEF SUMMARY: We estimated rates of reactions involved with the synthesis, storage, release, reuptake, and metabolism of dopamine in the putamen in PD and found that the main intraneuronal functional abnormality separating PD from controls was attenuated vesicular sequestration, implicating decreased vesicular uptake through the vesicular monoamine transporter and increased vesicular leakiness as key determinants of putamen dopamine deficiency in PD.

背景和目的:壳核多巴胺耗竭是帕金森病(PD)的特征。决定多巴胺储存的神经元内过程尚未得到系统研究。本研究探讨了多巴胺合成、囊泡储存和代谢对对照组-PD差异的相对贡献。方法:我们更新了2002年至2024年的体内研究汇总,涉及死后壳核组织中反应物的含量,包括自毒性多巴胺代谢产物3,4-二羟基苯乙醛(DOPAL),并计算了合成、囊泡和代谢指数。结果:在PD中,壳核多巴胺合成速率约为正常的3%。多巴胺的囊泡储存严重受损,约95%新合成的多巴胺从囊泡泄漏到细胞质中。细胞质多巴胺代谢产物DOPAL在PD中比对照组高约7倍。PD中的囊泡多巴胺泄漏大于囊泡单胺转运体2型(VMAT2)缺陷所能解释的程度,提示一种性质不同的囊泡储存失败。结论:在PD中,几乎所有新合成的多巴胺从囊泡储存泄漏到细胞质中,在那里被代谢为自毒性醛DOPAL,这可能构成致病的正反馈环路。

1. 原文摘要

Neuroinflammation is increasingly recognized as a core pathological process in various neurological diseases, including neurodegenerative disorders, stroke, autoimmune demyelinating diseases, and acute brain dysfunction associated with systemic inflammation. Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention.

neuroinflammation日益被认为是多种神经系统疾病的核心病理过程,包括神经退行性疾病、中风、自身免疫性脱髓鞘疾病以及与全身炎症相关的急性脑功能障碍。在其调节机制中,胆碱能抗炎通路将神经活动与免疫调节联系起来。然而,其神经学相关性超越了经典的外周迷走神经介导的炎症反射。在CNS内,乙酰胆碱(ACh)通过microglia上的α7烟碱型乙酰胆碱受体(alpha7nAChR)发挥直接的免疫调节作用,将其表型从促炎转变为抗炎。ACh还调节microglia的代谢重编程,从糖酵解转向氧化磷酸化,从而减轻neuroinflammation。在本综述中,我们讨论了CNS胆碱能抗炎通路,重点介绍ACh/alpha7nAChR介导的microglia免疫代谢重编程及其对AD和PD的神经保护意义,以及针对该通路的治疗策略。

三、本周重点趋势总结

AD 研究热点

本周 AD 研究的核心趋势集中在三个方面:

  1. 血液 circRNA 作为新一代 AD 早期诊断 biomarker(文献1,Nature Medicine):首次建立基于血液 circRNA 的 AD 早期诊断模型,在临床前 AD 检测中超越了当前金标准 pTau217(AUC 0.93 vs 0.88),且 circRNA 信号与 microglia 特异性基因相关,将诊断与机制紧密联系。
  2. TOP1 介导的神经元基因组不稳定性作为跨蛋白病的共同致病机制(文献2,Cell):以单细胞全基因组测序发现 ALS/FTD 和 AD 共享 TOP1 介导的 DNA 损伤模式,为跨疾病治疗提供了统一靶点,是该领域的重要理论突破。
  3. 肠道微生物组对 tau 病的特异性调控(文献14,Nature Communications):鉴定出特定微生物代谢产物(TMAO、吲哚酚硫酸等)可直接促进 tau 聚集,且这一机制仅存在于 tau 病模型而非 amyloid 模型中,提示 tau 病的微生物组干预具有亚型特异性。

PD 研究热点

本周 PD 研究有两个重要进展:

  1. 多巴胺囊泡储存失败的全新机制(文献19,Neurology):基于22年汇总数据揭示 PD 中95%新合成多巴胺从囊泡泄漏至细胞质,自毒性代谢产物 DOPAL 升高7倍,构成正反馈环路。这一囊泡储存失败超出了 VMAT2 缺陷可解释的范围,提示存在非 VMAT2 依赖的储存机制缺陷。
  2. CRISPR 基因校正增强 iPSC 多巴胺能细胞治疗(文献13,Advanced Science):在非人灵长类 PD 模型中12个月长期追踪证明,CRISPR 校正 LRRK2 突变可显著增强 iPSC 来源 DA 前体细胞的存活、纤维生长和功能恢复,为 PD 个性化细胞治疗铺平道路。

AD 与 PD 的共同机制

本周 AD+PD 交叉机制研究呈现三大主题:

  1. 蛋白病的交互与交叉 seeding:amyloid 加剧 tau 和 alpha-synuclein 病理(文献7);amylin 通过交叉 seeding 连接 T2D、AD 和 PD(文献11);TDP-43 功能障碍促进 tau 病理转化(文献9)。这些研究共同指向蛋白病之间存在多层次交互网络。
  2. 免疫系统从先天免疫到适应性免疫的全面参与:Nature Immunology 同期发表两篇综述——星形胶质细胞先天免疫信号(文献3)和适应性免疫在神经退行性变中的作用(文献4),将免疫学视角从 microglia 扩展到星形胶质细胞和 T/B 细胞;胆碱能抗炎通路通过 microglia 免疫代谢重编程调控 neuroinflammation(文献20)。
  3. 微生物组-脑轴的深入解析:口腔-肠道-脑轴综述(文献6)、牙龈蛋白酶(文献18)和微生物代谢产物促 tau 聚集(文献14)从不同角度揭示了微生物组对 AD/PD 的影响,且干预策略(如益生菌nisin、牙龈蛋白酶抑制剂)已有临床前和临床证据。

新靶点或新生物标志物

靶点/标志物 文献 类型 亮点
circRNA(34个血液标志物) 1 生物标志物 临床前AD检测优于pTau217

诊断、治疗、临床转化趋势

诊断趋势:从单蛋白标志物(pTau217)向多维度标志物平台(circRNA)发展;宏观结构标志物(脑不对称性)与微观蛋白标志物互补;微生物组相关标志物(唾液牙龈蛋白酶活性)作为可非侵入检测的早期风险分层工具。

治疗趋势:基因校正增强细胞治疗(文献13)、EphB1介导BBB瞬时开放增强纳米药物递送(文献16)、15-PGDH/PGE2/EP2 氧化还原修复通路(文献12)、RAS双重臂靶向(文献10)、amylin交叉seeding抑制剂(文献11)等均具有明确的转化路径。特别值得注意的是,文献12中15-PGDH抑制剂MF-300已进入人体临床试验(外周适应症),为PD治疗转化提供了近期可行性。

值得后续追踪的方向:circRNA血液标志物前瞻性验证队列、TOP1抑制剂在AD中的治疗潜力、VPS13C溶酶体修复机制的深入验证、牙龈蛋白酶抑制剂LHP588的Phase 2 SPRING临床试验、基于CRISPR校正的PD个性化细胞治疗的临床转化、amylin交叉seeding抑制剂的开发、运动-类淋巴系统-AD防治的纵向队列研究。
