Clinical Study

Figure 1

Representative gating and analysis of the frequency of CD8+ T cells that coexpressed CD38 and HLA-DR from HIV nondetectable group and HIV detectable group. Lymphocyte population is identified as a cell population with small forward scatter (FSC) and side scatter (SSC). Then, CD8+ T cells are identified by the expression of CD3 and CD8. The frequency of CD8+ T cells that expressed CD38 and HLA-DR is determined by the number in the upper right quadrant.
