Aging increases susceptibility to and severity of a variety of chronic and infectious diseases. Underlying this is dysfunction of the immune system, including chronic increases in low-grade inflammation (inflammaging) and age-related immunosuppression (immunosenescence). Growth differentiation factor-15 (GDF-15) is a stress-, infection-, and inflammation-induced cytokine which is increased in aging and suppresses immune responses. This mini review briefly covers existing knowledge on the immunoregulatory and anti-inflammatory roles of GDF-15, as well as its potential importance in aging and immune function.
衰老会增加对多种慢性疾病和传染病的易感性及患病严重程度。其根本原因是免疫系统功能失调,包括低度炎症(炎症衰老)的慢性增加和与年龄相关的免疫抑制(免疫衰老)。生长分化因子15(GDF-15)是一种由应激、感染和炎症诱导产生的细胞因子,在衰老过程中水平升高,并抑制免疫反应。这篇小型综述简要介绍了关于GDF-15的免疫调节和抗炎作用的现有知识,以及它在衰老和免疫功能中的潜在重要性。
