G蛋白偶联受体91 (GPR91)是琥珀酸特异性受体,激活GPR91可启动复杂的信号转导级联,上调炎症和促血管生成细胞因子。在视网膜中,GPR91主要在神经节细胞中表达,神经节细胞是参与糖尿病视网膜病变(DR)和其他缺氧性视网膜疾病发病的主要细胞实体。在DR和早产儿视网膜病变(ROP)的发展过程中,慢性缺氧导致局部琥珀酸盐水平升高。琥珀酸介导的GPR91激活通过ERK1/2-C/EBP β (c-Fos)和/或ERK1/2-COX-2/PGE2信号通路上调血管内皮生长因子(VEGF),进而导致这些疾病中血视网膜屏障的破坏。本文将简要介绍GPR91及其生物学功能,并对GPR91在DR和ROP中的作用和机制进行详细讨论。更好地了解GPR91的调控,对于寻找新的生物标志物和药物靶点,预测和治疗DR、ROP和缺氧性视网膜疾病具有重要意义。
G protein-coupled receptor 91 (GPR91) is a succinate-specific receptor and activation of GPR91 could initiate a complex signal transduction cascade and upregulate inflammatory and pro-angiogenic cytokines. In the retina, GPR91 is predominately expressed in ganglion cells, a major cellular entity involved in the pathogenesis of diabetic retinopathy (DR) and other hypoxic retinal diseases. During the development of DR and retinopathy of prematurity (ROP), chronic hypoxia causes an increase in the levels of local succinate. Succinate-mediated GPR91 activation upregulates vascular endothelial growth factor (VEGF) through ERK1/2-C/EBP β (c-Fos) and/or ERK1/2-COX-2/PGE2 signaling pathways, which in turn, leads to the breakdown of blood-retina barriers in these disorders. In this review, we will have a brief introduction of GPR91 and its biological functions and a more detailed discussion about the role and mechanisms of GPR91 in DR and ROP. A better understanding of GPR91 regulation may be of great significance in identifying new biomarkers and drug targets for the prediction and treatment of DR, ROP, and hypoxic retinal diseases.
