类风湿关节炎(RA)是一种常见的自身免疫性疾病,其发病机制涉及细胞因子、遗传和感染等多种因素,前列腺素E2(PGE2)是RA发生发展过程中重要的炎性介质之一,细胞因子如白细胞介素1(IL-1)和肿瘤坏死因子α(TNF—α)在RA的骨损伤中起重要作用。为阐明RA的发生机制和寻找更安全有效的治疗药物提供参考,现就PGE2和IL-1在RA发生中的作用、PGE2及其相关因素和IL-1的关系及治疗RA的药物作用机制研究作一概述。
Rheumatoid arthritis (RA) is a common autoimmunity disease. Many effective factors including cytokines, heredity and infection contribute to the pathogenesis process of RA. Prostaglandin E2 ( PGE2 ) is one of major inflammatory mediators. Cytokines such as interleukin-I ( IL-1 ) and tumor necrosis factor α (TNF-α) play important roles in the pathogenesis of bone loss associated with RA. This article clarifies the mechanism of PGE2 and IL-1 in pathogenesis of the RA and the relationship of PGE2 and its related factors to IL-1 as well as the pharmacological mechanism of drug used in the treatment of RA.
