克罗恩病(CD)是一种慢性炎症性肠病,其特征是由先天性和适应性免疫反应驱动的复发性透壁性肠道炎症。自噬是一个多步骤的过程,通过降解细胞内组分,如受损的细胞器和入侵的细菌,在维持细胞内稳态中起关键作用。CD中自噬的失调通过鉴定参与自噬的几种易感基因来揭示,包括ATG16L1、IRGM、NOD2、LRRK2、ULK1、ATG4和TCF4。在这篇综述中,改变自噬的粘膜先天免疫反应中的CD的背景下的作用进行了讨论,特别关注树突状细胞,巨噬细胞,潘氏细胞,杯状细胞。选择性自噬,如异嗜,ERphagy,和线粒体自噬,在维持这些先天性免疫细胞的肠道内稳态中发挥关键作用,进行了讨论。随着我们对CD发病机制中自噬的理解的发展,自噬靶向治疗的发展可能会使自噬受损的患者亚群受益。
Crohn’s disease (CD) is a chronic inflammatory bowel disease marked by relapsing, transmural intestinal inflammation driven by innate and adaptive immune responses. Autophagy is a multi-step process that plays a critical role in maintaining cellular homeostasis by degrading intracellular components, such as damaged organelles and invading bacteria. Dysregulation of autophagy in CD is revealed by the identification of several susceptibility genes, including ATG16L1, IRGM, NOD2, LRRK2, ULK1, ATG4, and TCF4, that are involved in autophagy. In this review, the role of altered autophagy in the mucosal innate immune response in the context of CD is discussed, with a specific focus on dendritic cells, macrophages, Paneth cells, and goblet cells. Selective autophagy, such as xenophagy, ERphagy, and mitophagy, that play crucial roles in maintaining intestinal homeostasis in these innate immune cells, are discussed. As our understanding of autophagy in CD pathogenesis evolves, the development of autophagy-targeted therapeutics may benefit subsets of patients harboring impaired autophagy.
