| 摘 要： | Hippo信号通路最初是在果蝇(Drosophila)中被发现的,是在进化上高度保守并能调控器官大小的信号转导通路。在哺乳动物多种组织器官中,Hippo信号通路的关键激酶MST1和MST2(果蝇Hippo激酶的同源分子)通过抑制下游的转录共激活分子YAP(果蝇中为Yorki)的活性来实现对细胞增殖和凋亡的调控。在这些组织器官中条件性敲除Mst1和Mst2或过表达Yap大都会造成细胞过度增殖或肿瘤的发生。近年来,随着研究的不断深入,Hippo信号通路不依赖于YAP的非经典功能也逐渐被发现。其中,Hippo信号通路多个成员在免疫系统中的调控功能逐渐成为该领域的研究热点,特别是在免疫细胞发育分化、机体自身免疫性疾病及应对病毒和细菌入侵等过程中所发挥的调控作用。本文重点阐述了Hippo信号通路在T淋巴细胞中发育、分化、活化和迁移等方面及在部分天然免疫细胞抗感染过程中的功能和调控。

| Abstract: | The Hippo signaling pathway, first identified in Drosophila, has emerged as a critical regulator for controlling the size of organs. Activation of the Hippo signaling pathway negatively regulates the Yorkie ortholog YAP in multiple organs, important in the regulation of cell proliferation, differentiation, and apoptosis during development. The Serine/Threonine protein kinases MST1 and MST2, mammalian homologs of the Drosophila Hippo kinase, play central roles in the Hippo signaling pathway in mammals. Recent studies reveal that non-canonical Hippo signaling pathways are also involved in the regulation of various other biological processes, particularly the important roles of MST1 and MST2 kinases in immune cell activation, adhesion, migration, growth, and apoptosis. In this review, we summarize the recent advances in understanding the roles of MST1 and MST2 kinases in the regulation of the functions of T lymphocytes and innate immune cells. |
