项目摘要
We recently reported two substances (ATRA and thalidomide) had preventive effects on pulmonary fibrosis by inhibiting IL-6-dependent proliferation and TGF-β_1-dependent transdifferentiation of lung fibroblasts. Rheumatoid arthritis is a chronic autoimmune disorder, and its pathogenesis is also characterized by an association with several cytokines. It has been reported that Calpain, a calcium-dependent intracellular cysteine protease, plays an important role in the progression of Rheumatoid arthritis. In this study, we examined the preventive effect of Calpeptin, a calpain inhibitor, on bleomycin-induced pulmonary fibrosis.Calpeptin histologically ameliorated bleomycin-induced pulmonary fibrosis in mice. Calpeptin decreased the expression of IL-6, TGF-β_1, angiopoietin-1, and collagen type Iα1 mRNA in mouse lung tissues. In vitro studies disclosed that Calpeptin reduced 1) production of IL-6, TGF-β_1, angiopoietin-1 and collagen synthesis from lung fibroblasts, and 2) both IL-6-dependent proliferation and angiopoietin-1-dependent migration of the cells, which could be the mechanism underlying the preventive effect of Calpeptin on pulmonary fibrosis.These data suggest the clinical use of Calpeptin for the prevention of pulmonary fibrosis.
我们最近报道了两种物质(ATRA和沙利度胺)通过抑制肺成纤维细胞的IL-6依赖性增殖和TGF-β_1依赖性转分化来预防肺纤维化。类风湿性关节炎是一种慢性自身免疫性疾病,其发病机制也有特点。据报道,钙蛋白酶(Calpain)是一种钙依赖性细胞内半胱氨酸蛋白酶,在类风湿性关节炎的进展中发挥着重要作用。在这项研究中,我们检测了钙蛋白酶抑制剂对博来霉素诱导的肺纤维化的预防作用。钙肽在组织学上改善了博莱霉素诱导的小鼠肺纤维化,降低了 IL-6、TGF-β_1、血管生成素-1、小鼠肺组织中 Iα1 型胶原蛋白 mRNA 的体外研究表明 Calpeptin 减少了 1) IL-6 的产生,肺成纤维细胞的 TGF-β_1、血管生成素-1 和胶原合成,2) 细胞的 IL-6 依赖性增殖和血管生成素-1 依赖性迁移,这可能是 Calpeptin 预防肺纤维化作用的机制。这些数据表明钙肽素可用于预防肺纤维化的临床应用。
