免疫作用在年龄相关性黄斑变性(AMD)的玻璃膜疣形成、视网膜色素上皮萎缩、脉络膜新生血管形成等病变形成过程中贯穿始终.视网膜为免疫赦免器官并维持自身免疫稳态,该稳态失衡时免疫反应过度则演变为慢性炎症,持久的炎症反应可导致眼内炎症细胞积累、补体分子积累、免疫复合物沉积,造成组织损伤.目前认为,免疫产物沉积于眼主要涉及慢性炎症、亚炎症、自我吞噬功能失代偿等机制.本文就近年来在视网膜老化、免疫异常、自我吞噬作用与AMD发生发展相关的研究进展做一综述.
免疫作用在年齡相關性黃斑變性(AMD)的玻璃膜疣形成、視網膜色素上皮萎縮、脈絡膜新生血管形成等病變形成過程中貫穿始終.視網膜為免疫赦免器官併維持自身免疫穩態,該穩態失衡時免疫反應過度則縯變為慢性炎癥,持久的炎癥反應可導緻眼內炎癥細胞積纍、補體分子積纍、免疫複閤物沉積,造成組織損傷.目前認為,免疫產物沉積于眼主要涉及慢性炎癥、亞炎癥、自我吞噬功能失代償等機製.本文就近年來在視網膜老化、免疫異常、自我吞噬作用與AMD髮生髮展相關的研究進展做一綜述.

Immune mechanism plays an important role in pathology of AMD,including formation of drusen,geographic atrophy and choroidal neovascularization (CNV). Retina is an " immune privileged" site,which could maintain immune homeostasis in one 's life. Disruption of this homeostatic mechanisms seems crucial in allowing excessive activation of immunologic response and the resultant chronic inflammation,which could lead to accumulation of resident immune cells,complement components and deposition of immune complex,all above may result in ocular tissue damage and degeneration.At present,deposition of immunoreactive products in ocular tissues is involved in chronic inflammation,para-inflammation,dysfunction of autophagy and so on.This article reviews recent studies on development of AMD relevant to retina aging,dysfunction of immunity and autophagy.
