免疫细胞的发育和功能必须通过细胞表面受体进行严格调节,以确保对病原体的适当反应和对自身的耐受性。在T细胞中,来自T细胞受体的信号对于T细胞成熟、稳态和活化是必需的。在肥大细胞中,IgE的高亲和力受体转导促进肥大细胞存活并诱导肥大细胞活化的信号。在树突状细胞和巨噬细胞中,Toll样受体识别微生物病原体,并在针对病原体的先天性和适应性免疫中发挥关键作用。我们的研究探索了这些受体的信号是如何转导和调节的,以更好地了解这些免疫细胞。我们最近的研究已经揭示了二酰基甘油激酶和TSC 1/2-mTOR作为T细胞、肥大细胞、树突状细胞和巨噬细胞中的关键信号分子/调节剂。
Immune cell development and function must be tightly regulated through cell surface receptors to ensure proper responses to pathogen and tolerance to self. In T cells, the signal from the T-cell receptor is essential for T-cell maturation, homeostasis, and activation. In mast cells, the high-affinity receptor for IgE transduces signal that promotes mast cell survival and induces mast cell activation. In dendritic cells and macrophages, the toll-like receptors recognize microbial pathogens and play critical roles for both innate and adaptive immunity against pathogens. Our research explores how signaling from these receptors is transduced and regulated to better understand these immune cells. Our recent studies have revealed diacylglycerol kinases and TSC1/2-mTOR as critical signaling molecules/regulators in T cells, mast cells, dendritic cells, and macrophages.
