Correlation between naïve CD4 (CD4⁺CD45RA⁺) or activated CD8 (CD8⁺CD38⁺) T lymphocytes with HIV-1 viral Load. Panels A and B depict a negative correlation between CD4+CD45RA+ (naive cells) and HIV-1 viral load in both co-infected and HIV-1 subjects. By contrast, lower panels show a positive correlation between CD8+ CD38 (activated cells, C and D) and HIV-1 viral load in both co-infected and HIV-1 subjects.
