摘要

人们越来越认识到阿尔茨海默病(AD)不仅是由中枢神经系统病理形成的,而且是由肠道、大脑和免疫系统之间复杂的双向相互作用形成的。本综述综合了阿尔茨海默病中肠-脑免疫失调的新证据,特别关注慢性应激、微生物失衡和神经免疫信号如何汇聚影响疾病风险和进展。我们超越了传统的以微生物组为中心的观点,纳入了非微生物肠道来源的介质,包括肠内分泌激素、胆汁酸和迷走神经肽,它们有助于免疫调节、神经传递和大脑稳态。重要的是,我们强调ad相关的神经退行性变也可以反馈损害胃肠道功能和微生物组成,创造一个自我强化的病理循环。这篇综述整合了宿主遗传多态性(如APOE4和TREM2)在调节肠道通透性、免疫调节和微生物群特征中的作用的最新发现,强调了基因组-微生物群相互作用形成AD易感性的系统生物学模型。我们还探讨了单细胞组学技术和多器官框架如何在细胞分辨率上重新定义我们对肠-脑免疫回路的理解。翻译部分批判性地评估当前和潜在的治疗策略,包括饮食、微生物、行为和内分泌干预,同时解决将临床前研究结果应用于不同疾病人群的挑战。通过结合年龄,阶段和基因型特异性因素,本综述提供了AD中肠-脑应激轴的全面和及时的综合,将其定位为机制研究和精确治疗开发的关键前沿。

Gut-brain relationship in dementia and Alzheimer's disease: Impact on stress and immunity
Alzheimer’s disease (AD) is increasingly recognized as a condition shaped not only by central nervous system pathology but also by complex, bidirectional interactions between the gut, brain, and immune system. This review synthesizes emerging evidence on gut-brain-immune dysregulation in AD, with particular attention to how chronic stress, microbial imbalance, and neuroimmune signaling converge to influence disease risk and progression. We move beyond traditional microbiome-focused perspectives to incorporate non-microbial gut-derived mediators, including enteroendocrine hormones, bile acids, and vagal neuropeptides, which contribute to immune modulation, neurotransmission, and brain homeostasis. Importantly, we highlight that AD-related neurodegeneration can also feedback to impair gastrointestinal function and microbial composition, creating a self-reinforcing pathological loop. The review integrates recent findings on the role of host genetic polymorphisms, such as APOE4 and TREM2, in modulating gut permeability, immune tone, and microbiota profiles—emphasizing a systems biology model in which genome-microbiome interactions shape AD susceptibility. We also explore how single-cell omics technologies and multi-organ frameworks are redefining our understanding of gut-brain-immune circuits at cellular resolution. The translational section critically evaluates current and potential therapeutic strategies, including dietary, microbial, behavioral, and endocrine interventions, while addressing the challenges of applying preclinical findings to diverse human populations across the disease spectrum. By incorporating age-, stage-, and genotype-specific considerations, this review offers a comprehensive and timely synthesis of the gut-brain-stress axis in AD, positioning it as a key frontier in mechanistic research and precision therapeutic development.

期刊介绍: With the rise in average human life expectancy, the impact of ageing and age-related diseases on our society has become increasingly significant. Ageing research is now a focal point for numerous laboratories, encompassing leaders in genetics, molecular and cellular biology, biochemistry, and behavior. Ageing Research Reviews (ARR) serves as a cornerstone in this field, addressing emerging trends. ARR aims to fill a substantial gap by providing critical reviews and viewpoints on evolving discoveries concerning the mechanisms of ageing and age-related diseases. The rapid progress in understanding the mechanisms controlling cellular proliferation, differentiation, and survival is unveiling new insights into the regulation of ageing. From telomerase to stem cells, and from energy to oxyradical metabolism, we are witnessing an exciting era in the multidisciplinary field of ageing research. The journal explores the cellular and molecular foundations of interventions that extend lifespan, such as caloric restriction. It identifies the underpinnings of manipulations that extend lifespan, shedding light on novel approaches for preventing age-related diseases. ARR publishes articles on focused topics selected from the expansive field of ageing research, with a particular emphasis on the cellular and molecular mechanisms of the aging process. This includes age-related diseases like cancer, cardiovascular disease, diabetes, and neurodegenerative disorders. The journal also covers applications of basic ageing research to lifespan extension and disease prevention, offering a comprehensive platform for advancing our understanding of this critical field.
