The percentage of CD8+ T cells secreting IL-17A was significantly increased (p=0.015) and the percentages of CD4+ and CD8+ T cells secreting TNF-α, and percentage of CD14+ monocytes secreting TNF-α were significantly decreased (p=0.013; p=0.001; p<0.001) in the HT group than in the HIV group. This evidence concerns the gene CD8A and hematocrit.
