CD4 and infection: No significant correlation was found between the CD86 expression, as assessed by percentage or geomean FI, and percentage of CD4 T cell (r = −0.0699 for HIV-1; r = −0.08539 for HIV-2, in the case of CD86 geomean FI) or viremia (r = −0.01922 for HIV-1; r = 0.1975 for HIV-2, in the case of CD86 geomean FI) in both infections.
