Abstract

Upon insult, such as infection or tissue injury, the innate and adaptive immune systems initiate a series of responses to defend the body. Recent studies from immune cell-specific androgen receptor (AR) knockout mice demonstrated that androgen and its receptor (androgen/AR) play significant roles in both immune regulations. In the innate immunity, androgen/AR is required for generation and proper function of neutrophils; androgen/AR also regulates wound healing processes through macrophage recruitment and proinflammatory cytokine production. In adaptive immunity, androgen/AR exerts suppressive effects on development and activation of T and B cells. Removal of such suppression causes thymic enlargement and excessive export of immature B cells. Altogether, androgen/AR plays distinct roles in individual immune cells, and targeting androgen/AR may help in treatment and management of immune-related diseases.

摘要

受到侮辱时,如感染或组织损伤,先天和适应性免疫系统会启动一系列反应来保护身体。最近来自免疫细胞特异性雄激素受体 (AR) 敲除小鼠的研究表明,雄激素及其受体 (雄激素/AR) 在免疫调节中发挥重要作用。在先天免疫中,雄激素/AR 是中性粒细胞生成和正常功能所必需的;雄激素/AR 还通过招募巨噬细胞和产生促炎细胞因子来调节伤口愈合过程。在适应性免疫中,雄激素/AR 对 T 和 B 细胞的发育和激活具有抑制作用。这种抑制作用的消除会导致胸腺增大和不成熟 B 细胞的过度输出。总的来说,雄激素/AR 在单个免疫细胞中发挥不同的作用,靶向雄激素/AR 可能有助于治疗和管理与免疫相关的疾病。
