自噬降解细胞质成分,对发育和人类健康很重要。虽然自噬被认为受到系统性细胞间信号的影响,但控制自噬的蛋白质在很大程度上被认为在单个细胞内起作用。在这里,我们报告说,果蝇巨球蛋白补体相关(Mcr),补体直向同源物,在发育过程中的细胞死亡和炎症中起着至关重要的作用,通过影响邻近细胞的自噬。Mcr的这一功能涉及免疫受体德雷珀,这表明自噬与炎症控制之间的关系。有趣的是,上皮细胞中的Mcr功能是巨噬细胞自噬和迁移到上皮伤口所必需的,这是一个Draper依赖性过程。这项研究出乎意料地揭示了,来自一个细胞的补体相关通过一个古老的免疫信号程序调节邻近细胞的自噬。果蝇中的补体直向同源物通过影响邻近细胞中的自噬在发育细胞死亡和炎症过程中起重要作用。
Autophagy degrades cytoplasmic components and is important for development and human health. Although autophagy is known to be influenced by systemic intercellular signals, the proteins that control autophagy are largely thought to function within individual cells. Here we report that Drosophila Macroglobulin complement-related (Mcr), a complement orthologue, plays an essential role during developmental cell death and inflammation by influencing autophagy in neighboring cells. This function of Mcr involves the immune receptor Draper, suggesting a relationship between autophagy and the control of inflammation. Interestingly, Mcr function in epithelial cells is required for macrophage autophagy and migration to epithelial wounds, a Draper-dependent process. This study reveals, unexpectedly, that complement-related from one cell regulates autophagy in neighboring cells via an ancient immune signaling program. A complement orthologue in Drosophila plays an essential role during developmental cell death and inflammation by influencing autophagy in neighboring cells.
