ABSTRACT
Objective:
To analyze the phenotypes of γδ T cell in acute HIV-infected patients,and to clarify the role of γδ T cell in acute HIV infection(AHI).Methods:
The expressions of CD38,programmed cell death protein-1(PD-1),CD160,CD95 and tumor necrosis factor-related apoptosis inducing ligand-death receptor 5 ( TRAIL-DR5 ) were detected by using flow cytometry.Results:
Compared with healthy controls,the frequencies of Vδ1 T cells were significantly increased and the frequencies of Vδ2 T cells were de-creased,however,the frequencies of total γδ T cells were not significantly changed in acute HIV-infected patients. The frequencies of CD38+γδ T cells,CD38+Vδ1 T cells and CD38+Vδ2 T cells were significantly increased compared with healthy controls. Moreover, compared with healthy controls,the frequencies of PD-1+γδ T cells and DR5+γδ T cells were increased,but the expression of PD-1 and DR5 on Vδ1 and Vδ2 T cells were not significantly changed. However,the frequencies of CD38+Vδ1 T cells,CD160+Vδ1 T cells,PD-1+Vδ1 T cells,CD95+Vδ1 T cells and DR5+Vδ1 T cells were significantly increased compared with Vδ2 T cells in acute HIV-infected patients.Conclusion:
Activation,inhibitor and apoptosis markers are highly expressed on γδ T cells,especially on Vδ1 T cells in acute HIV-infected patients,suggest that Vδ1 T cells play more important roles in acute HIV infection and disease progression.
