摘要
松弛素(重组人松弛素 2 激素;RLX-2;serelaxin)作为一种新的治疗纤维化疾病的药物引起了人们的期望。大量的体外和体内研究提供了令人信服的证据,即松弛素促进结缔组织细胞外基质的重塑,通过抑制多种纤维化途径介导,特别是转化生长因子 (TGF)-β1(一种主要的促纤维化细胞因子)的下游信号传导,以及肌成纤维细胞(主要的纤维化生成细胞)的募集和激活。然而,所有在纤维化疾病患者中使用松弛素的临床试验都给出了不确定的结果。在这篇综述中,我们总结了纤维化的分子机制,重点介绍了松弛素可以有效靶向的分子机制。然后,我们对迄今为止使用松弛素作为抗纤维化药物进行的临床试验进行了严格的重新评估,以突出其优势和劣势的关键点,并确定松弛素或其治疗用途的一些未来机会。类似物,在我们认为值得研究的纤维化疾病和病理性瘢痕形成中。
