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