Again, no significant correlation was found between PD-L1 expression and percentage of CD4 T cell (r = 0.1200 for HIV-1; r = −0.02762 for HIV-2, in the case of PD-L1 geomean FI), or viremia (r = −0.02476 for HIV-1; r = −0.2501 for HIV-2, in the case of PD-L1 geomean FI), or the T cell activation markers assessed in both infections. This evidence concerns the gene CD4 and infection.
