FIGURE 1. HIV infection does not significantly alter cell surface expression of HIV chemokine coreceptors or macrophage activation markers.
(A) Representative flow cytometry analyses of CD68 (n = 15, P = 0.398) expression and HIV-1 coreceptors, CCR5 (n = 10, P = 0.301) and CXCR4 (n = 9, P = 0.625), expression directly before and after HIV-1BaL infection. (B) Representative flow cytometry analyses of the expression CD40 (n = 11, P = 0.898), CD163 (n = 14, P = 0.787) and CD11b (n = 6, P = 0.363) in CD68+ macrophages directly before and after HIV-1BaL infection. Wilcoxon signed rank test was used for statistical analysis
