The level of PD-1H expression on monocytes in HIV-infected individuals correlates with immune activation and CD4 T cell depletion, but not viral load.

<p>Correlation of PD-1H expression on monocytes with (a) immune activation/exhaustion markers CD38, PD-1 and HLA-DR on CD4 and CD8 T cell subsets (b) viral loads and (c) CD4 counts. (n = 35). r and p values determined by Spearmans non parametric test values. p<0.05 were considered significant.
