促纤维化/抗纤维化因子失衡与肾脏纤维化

Fibrosis/Anti-fibrosis Factor Imbalance and Renal Fibrosis

肾脏纤维化基本病理过程是细胞外基质过多地积聚、沉积及降解不足。主要的致纤维化细胞因子-转化生长因子刺激肾小球系膜细胞、成纤维细胞和肾小管上皮细胞表型的活化或转变,产生大量的细胞外基质;而主要的抗纤维化细胞因子-肝细胞生长因子可以抑制肾小管上皮细胞转分化,从而抑制肾小球系膜及间质纤维化。目前认为促纤维化与抗纤维化细胞因子的失衡是肾脏纤维化发生、发展的重要机制。

The pathogenesis of renal fibrosis is characterized by an excessive accumulation and deposi-tion of extracelluler matrix components.Among many fibrogenic factors,transforming growth factor-β/smad plays a central role,leading to activation or transformation of mesangial cells,fibrolast cells and tublucar epi-thelical cells,generating massive extracelluler matrix.In many aspects,the effects of the primary antifibrotic factor-hepatocyte growth factor on kidney cell are exactly the opposite .It′s now considered that the imbalance of the fibrosis cytokines and the antifibrosis cytokines is an important mechanism of renal fibrosis .
