TRAF3 is an adapter protein that serves and regulates the functions of several types of receptors, located both inside the cell and at the plasma membrane. These include members of the TNF receptor superfamily (TNFR-SF), toll-like receptors (TLR), and cytokine receptors. It has become increasingly evident that the roles and functions of TRAF3 are highly context-dependent. TRAF3 can serve distinct roles for different receptors in the same cell, and also has highly cell-type-dependent functions. This review focuses upon the current state of knowledge regarding how TRAF3 regulates the biology and effector functions of B and T lymphocytes, two major cell types of the adaptive immune response in which TRAF3 has markedly distinct roles.
TRAF3 是一种衔接蛋白,既能在细胞内,也能在质膜上,为多种类型的受体提供服务并调节其功能。这些受体包括肿瘤坏死因子受体超家族(TNFR-SF)成员、 Toll 样受体(TLR)和细胞因子受体。越来越明显的是,TRAF3 的作用和功能高度依赖于背景。TRAF3 可以为同一细胞中不同的受体提供不同的作用,并且具有高度依赖细胞类型的功能。本综述重点介绍了目前关于 TRAF3 如何调节 B 和 T 淋巴细胞生物学和效应功能的知识状态,TRAF3 在这两种适应性免疫反应的主要细胞类型中具有显著不同的作用。
