Alzheimer´s disease (AD) stands out as the most common chronic neurodegenerative disorder. AD is characterized by progressive cognitive decline and memory loss, with neurodegeneration as its primary pathological feature. The role of neuroinflammation in the disease course has become a focus of intense research. While microglia, the brain's resident macrophages, have been pivotal to study central immune inflammation, recent evidence underscores the contributions of other cellular entities to the neuroinflammatory process. In this article, we review the inflammatory role of microglia and astrocytes, focusing on their interactions with AD's core pathologies, amyloid beta deposition, and tau tangle formation. Additionally, we also discuss how different modes of regulated cell death in AD may impact the chronic neuroinflammatory environment. This review aims to highlight the evolving landscape of neuroinflammatory research in AD and underscores the importance of considering multiple cellular contributors when developing new therapeutic strategies.
阿尔茨海默病(AD)是最常见的慢性神经退行性疾病。AD 的特征是进行性认知能力下降和记忆力丧失,神经退行性变是其主要的病理特征。神经炎症在疾病过程中的作用已成为研究的焦点。虽然小胶质细胞是大脑的常驻巨噬细胞,对中枢免疫炎症的研究至关重要,但最近的证据强调了其他细胞实体对神经炎症过程的贡献。在本文中,我们回顾了小胶质细胞和星形胶质细胞的炎症作用,重点讨论了它们与 AD 的核心病理学、β淀粉样蛋白沉积和tau 缠结形成的相互作用。此外,我们还讨论了 AD 中不同的细胞死亡方式如何影响慢性神经炎症环境。本综述旨在强调 AD 中神经炎症研究的不断发展,并强调在开发新的治疗策略时考虑多种细胞贡献的重要性。
