摘要
细胞自噬在固有免疫和获得性免疫中发挥重要作用。自噬一方面通过溶酶体清除胞质内微生物,发挥天然抗感染免疫作用;另一方面可通过调节抗原加工、呈递,在获得性免疫反应中发挥效应。自噬除可参与并增强组织相容性复合物(MHC)Ⅱ类分子的抗原呈递外,在经典和非经典MHCⅠ类抗原呈递中也发挥辅助作用。
Autophagy plays an important role in the innate and adaptive immune. On one hand,it acts as an innate immune response when eliminating microbes in cells via lysosome degradation; on the other hand,it acts effectively in adaptive immunity by regulating antigen processing and presentation. Autophagy is not only involved in and enhances major histocompatibility complex (MHC) II antigen presentation,but it also assists with classic and nonclassic MHC I antigen presentation.
