2、机制之一,可能与 Nogo 受体下游分子 Rho 激酶表达变化有关。相关结果发表在中国神经再生研究(英文版) 杂志 2014 年 4 月第 8 期。荧光免疫组化染色显示抑制Nogo受体表达的糖尿病大鼠视网膜神经节细胞内ROCK阳性表达减少Article: “ Upregulation of Nogo receptor expression induces apoptosis of retinal ganglion cells in diabetic rats,“ by Xuezheng Liu1, Zhongfu Zuo1, Wanpeng Liu1, Zhiyun Wang1, Yang H

5、tor of nerve regeneration inhibition, neuronal atrophy and even apoptosis. Upregulation of NgR expression is an important cause of cell apoptosis and visual extinction in some diseases including glaucoma. Whether ganglion cell apoptosis is related to NgR gene expression in diabetes mellitus remains
6、poorly understood. Dr. Xuezheng Liu and his team, Liaoning Medical University, China interfered NgR expression in the retinal ganglion cells of rats with diabetes mellitus and found that Rho kinase expression was obviously inhibited and retinal ganglion cell apoptosis was evidently reduced in rats w

These results indicate that upregulation of NgR expression is an important mechanism of retinal ganglion cell apoptosis in rats with diabetes mellitus, which is likely to be related to changes in Rho kinase expression in NgR downstream molecules. Related results were published
