摘要

获得性免疫缺陷综合征(AIDS)痴呆复合体(ADC)的发病机制尚不清楚。然而,最近的研究表明,暴露于hiv -1感染的巨噬细胞/小胶质细胞释放的病毒成分或细胞因子会损害神经元和星形胶质细胞的功能。我们发现,将原代培养的大鼠星形胶质细胞暴露于主要的HIV包膜糖蛋白gp120中会导致离子和溶质运输的改变,这可能导致神经元细胞损伤。

gp120-mediated alterations in astrocyte ion transport

The pathogenesis of the acquired immuno-deficiency syndrome (AIDS) dementia complex (ADC) is unknown. However, recent work indicates that neurons and astrocytes are functionally compromised by exposure to viral components or cellular factors released from HIV-1-infected macrophages/microglia. We show that exposure of primary cultured rat astrocytes to the major HIV envelope glycoprotein gp120 results in alterations of ion and solute transport that may contribute to neuronal cell injury.
