抗Thy1.1抗体诱导的肾炎模型及其在中药研究中的应用

Nephritic model induced by anti-Thy1.1 monoclonal antibody and its application to study on Chinese materia medica

抗Thy1.1单克隆抗体诱导的抗Thy1.1抗体肾炎模型广泛应用于人类系膜增殖性肾炎的研究领域。该模型的病理特征包括补体依赖性系膜溶解、肾小球内炎症细胞浸润、显著的蛋白尿,以及急性或进展性系膜损伤。文章综述了经静脉注射单克隆抗体1-22-3诱导的可逆性抗Thy1.1抗体肾炎模型和不可逆性抗Thy1.1抗体肾炎模型的病理特征;阐述了肾小球内炎症细胞浸润和各种损伤性细胞因子的变化规律;分析了包括系膜细胞增殖和细胞外基质沉积在内的复杂的系膜损伤病变过程。运用该模型,可以说明雷公藤多苷、柴苓汤等中药对系膜损伤和蛋白尿的药理作用,并且,在分子水平阐明这些药物对各种损伤因子的作用机制。

The anti-Thy1. 1 glomerulonephritis （GN） model induced by anti-Thy1. 1 monoclonal antibody （mAb） is a widely used animal model for human mesangial proliferative glomerulonephritis （ MsPGN）, which is characterized by significant proteinuria and acute or progressive mesangial injury following the complement-mediated mesangiolysis and glomerular inflammatory cell infiltration. In this review, it has been discussed that the pathogenesis of reversible anti-Thy1. 1 GN or irreversible anti-Thy1. 1 GN induced by mAb 1-22-3 injection, the mechanisms governing inflammatory cells infiltration and several injurious cytokines in glomeruli, and some of the processes involved in the resolution of mesangial lesion such as mesangial cell proliferation and matrix expansion. Using these models, it has been reported to examine the effects of Chinese materia medica, including multi-glycoside of Tripterygium wilfordii Hook. f. （GTW） and Sairei-to on mesangial damage and proteinuria, and then to clarify the mechanism of these herbs at molecular level by examining the effects on various injurious factors.
