内质网应激与急性肺损伤恶化关联性的研究进展
急性肺损伤(ALI)是一种严重威胁全球人类生命健康的疾病,其主要病理特征为肺泡上皮细胞和肺毛细血管内皮细胞的损伤,导致弥漫性肺间质水肿和肺泡水肿,通常伴有急性低氧性呼吸功能不全。内质网应激(ERS)在ALI的发生和发展过程中扮演着关键角色。它通过多种途径加剧急性肺损伤:在细胞凋亡方面,关键蛋白如GRP78、CHOP和caspase-12参与调控,促进肺血管内皮细胞和肺泡上皮细胞的凋亡,从而加重肺组织损伤;在ROS代谢方面,诱导活性氧(ROS)的大量释放,NADPH氧化酶等参与ROS的产生过程,ROS会损害肺血管内皮细胞,导致液体渗漏,进一步加剧肺损伤;在炎症反应方面,激活中性粒细胞,补体产生的...
