用HIV-1感染原代CD 4 + T细胞与糖酵解增加一致。我们研究了人类CD 4 + T细胞在HIV-1感染后葡萄糖转运蛋白(GLUT)和糖酵解酶的表达。我们证明了GLUT 1,GLUT 3,GLUT 4和GLUT 6在活化后的人CD 4 + T细胞中的共表达,以及它们在HIV-1感染细胞中的协同过表达。糖酵解酶的研究表明,人类CD 4 + T细胞中己糖激酶HK 1和HK 2的活化依赖性表达,以及响应HIV-1感染的细胞己糖激酶活性的高度显著增加。HIV-1感染的CD 4 + T细胞显示HK 1以及功能相关的电压依赖性阴离子通道(VDAC)蛋白的表达显著增加,但HK 2没有增加。在HIV-1感染的细胞中GLUT、HK 1和VDAC表达的升高反映了复制动力学,并且依赖于病毒复制,如逆转录抑制剂的使用所证明的。最后,我们证明了HK 1在HIV-1感染的CD 4 + T细胞中的上调不依赖于病毒辅助蛋白Vpu、Vif、Nef和Vpr。虽然这些数据与HIV-1对CD 4 + T细胞葡萄糖代谢的依赖性一致,但不能排除对感染的细胞反应机制。
Infection of primary CD4+ T cells with HIV-1 coincides with an increase in glycolysis. We investigated the expression of glucose transporters (GLUT) and glycolytic enzymes in human CD4+ T cells in response to infection with HIV-1. We demonstrate the co-expression of GLUT1, GLUT3, GLUT4, and GLUT6 in human CD4+ T cells after activation, and their concerted overexpression in HIV-1 infected cells. The investigation of glycolytic enzymes demonstrated activation-dependent expression of hexokinases HK1 and HK2 in human CD4+ T cells, and a highly significant increase in cellular hexokinase enzyme activity in response to infection with HIV-1. HIV-1 infected CD4+ T cells showed a marked increase in expression of HK1, as well as the functionally related voltage-dependent anion channel (VDAC) protein, but not HK2. The elevation of GLUT, HK1, and VDAC expression in HIV-1 infected cells mirrored replication kinetics and was dependent on virus replication, as evidenced by the use of reverse transcription inhibitors. Finally, we demonstrated that the upregulation of HK1 in HIV-1 infected CD4+ T cells is independent of the viral accessory proteins Vpu, Vif, Nef, and Vpr. Though these data are consistent with HIV-1 dependency on CD4+ T cell glucose metabolism, a cellular response mechanism to infection cannot be ruled out.
