Renal fibrosis is a common pathological change from development to end-stage renal diseases in all progressive chronic kidney diseases. Renal fibrosis after kidney transplantation will severely affect the renal graft function. Macrophages are characterized with high heterogeneity and plasticity. During the process of kidney injury, macrophages are recruited, activated and polarized by local microenvironment, and participate in the process of renal tissue injury, repair and fibrosis through multiple mechanisms. Recent studies have shown that macrophages may transit into myofibroblasts and directly participate in the formation of renal fibrosis. This process is known as macrophage-myofibroblast transition. Nevertheless, the regulatory mechanism remains elusive. In this article, the role of macrophages in renal fibrosis, the characteristics of macrophage-myofibroblast transition and the possible regulatory mechanism were reviewed, aiming to provide reference for relevant research of renal fibrosis.

目的观察低氧环境对小鼠肾小球内皮细胞(MGEC)透通性的影响,并探讨其机制。方法取处于对数生长期的MGEC,将细胞分为低氧1组、低氧2组、抑制剂1组、抑制剂2组和对照组。低氧1、2组分别在10%、5%氧浓度的低氧环境中培养36 h;抑制剂1、2组细胞先加入重组人VEGF抑制剂继续培养48 h,然后分别在10%、5%氧浓度的低氧环境培养36 h;对照组细胞常规培养,不做特殊处理。各组细胞分别于低氧处理0、12、24、36 h测算单层MGEC对白蛋白的通透率,反映细胞通透性;采用real-time PCR法检测小鼠MGEC中的VEGF mRNA。结果低氧1组、低氧2组培养0、12、24、36 h时细胞通透率逐渐升高,同组不同时点相比,P均<0.05;低氧1、2组培养12、24、36 h细胞通透率高于抑制剂1、2组及对照组(P均<0.05)。低氧处理12、24、36 h低氧2组细胞通透率高于低氧1组。低氧1、2组培养0、12、24、36 h时细胞中VEGF mRNA相对表达量均逐渐升高,组内不同时点相比,P均<0.05;低氧1、2组培养12、24、36 h细胞中VEGF mRNA相对表达量高于抑制剂1、2组及对照组,且低氧2组VEGF mRNA相对表达量高于低氧1组(P均<0.05)。结论低氧环境下小鼠MGEC通透性升高,可能与细胞中VEGF mRNA表达上调有关。 [ABSTRACT FROM AUTHOR]
