自噬的免疫调节作用和机制

Autophagy is a major pathway for degradation of cellular components and it contributes to the survival, differentiation, development, and dynamic homeostasis of organisms. Recent studies have demonstrated that autophagic mechanisms act as the effectors of immune systems, pattern recognition receptors and cy-tokines to clean the invasive pathogens in the cells. It was also found that immune systems recognize the invasive pathogens via monitoring the autophagic products. This pathway delivers the cytoplasmic material for lysosomal hydrolysis and presents the antigens to MHC Ⅱ molecules so as to activate the CD4 + T cells. Importantly, autophagy can couple with signaling for stress responses of cells and/or inflammatory responses to function as a defense. This paper reviewed the advance of rapidly developing research field and introduced the molecular mechanisms that autophagy regulates innate and adaptive immunity. These studies will deepen our understanding the mechanisms of immune responses and may provide a novel therapeutic strategy for autophage-associated diseases.
