IL-36 is a member of the IL-1 superfamily and consists of three agonists and one receptor antagonist (IL-36Ra). The three endogenous agonists, IL-36α, -β, and -γ, act primarily as proinflammatory cytokines, and their signaling through the IL-36 receptor (IL-36R) promotes immune cell infiltration and secretion of inflammatory and chemotactic molecules. However, IL-36 signaling also fosters secretion of profibrotic soluble mediators, suggesting a role in fibrotic disorders. IL-36 isoforms and IL-36 have been implicated in inflammatory diseases including psoriasis, arthritis, inflammatory bowel diseases, and allergic rhinitis. Moreover, IL-36 has been connected to fibrotic disorders affecting the kidney, lung, and intestines. This review summarizes the expression, cellular source, and function of IL-36 in inflammation and fibrosis in various organs, and proposes that IL-36 modulation may prove valuable in preventing or treating inflammatory and fibrotic diseases and may reveal a mechanistic link between inflammation and fibrosis.
白细胞介素-36（IL-36）是白细胞介素-1超家族的成员，由三种激动剂和一种受体拮抗剂（IL-36Ra）组成。三种内源性激动剂，即IL-36α、-β和-γ，主要作为促炎细胞因子发挥作用，它们通过IL-36受体（IL-36R）发出的信号促进免疫细胞浸润以及炎症和趋化分子的分泌。然而，IL-36信号传导也促进促纤维化可溶性介质的分泌，提示其在纤维化疾病中发挥作用。IL-36同工型和IL-36已被证实与包括银屑病、关节炎、炎症性肠病和变应性鼻炎在内的炎症性疾病有关。此外，IL-36还与影响肾脏、肺和肠道的纤维化疾病相关。本综述总结了IL-36在各种器官的炎症和纤维化中的表达、细胞来源及功能，并提出调节IL-36可能对预防或治疗炎症性和纤维化疾病具有重要价值，且可能揭示炎症与纤维化之间的机制联系。
