Cadwell和Debnath为我们对自噬相关蛋白的非自噬功能及其在疾病中的作用的新认识提供了一个视角。介导胞质物质大量降解的保守自噬相关蛋白(ATG)的鉴定为将自噬与一系列生理过程和疾病状况联系起来奠定了基础。最近的发现表明,这些相同的ATG编排的过程与经典的自噬有关,但又明显不同。自噬相关的功能包括分泌、吞噬物质的运输、病毒颗粒的复制和排出以及炎症和免疫信号级联的调节。在这里,我们定义了依赖于ATG的共同过程,并讨论了从这些相关途径中机械分离自噬的挑战。阐明区分个体ATGs功能的分子事件有望提高我们对从自身免疫到癌症等疾病起源的理解。
Cadwell and Debnath provide a perspective on our emerging understanding of the nonautophagic functions of autophagy-related proteins and their role in disease. The identification of conserved autophagy-related proteins (ATGs) that mediate bulk degradation of cytosolic material laid the foundation for breakthroughs linking autophagy to a litany of physiological processes and disease conditions. Recent discoveries are revealing that these same ATGs orchestrate processes that are related to, and yet clearly distinct from, classic autophagy. Autophagy-related functions include secretion, trafficking of phagocytosed material, replication and egress of viral particles, and regulation of inflammatory and immune signaling cascades. Here, we define common processes dependent on ATGs, and discuss the challenges in mechanistically separating autophagy from these related pathways. Elucidating the molecular events that distinguish how individual ATGs function promises to improve our understanding of the origin of diseases ranging from autoimmunity to cancer.
