Representative dot plots from breast milk and blood samples of an HIV-1-infected woman (no 8) (A) Gating strategy to explore breast milk CD4⁺ T cells and CD8⁺ T cells. (B) Analysis of CD38 and HLA-DR cell-surface expression on breast milk CD4⁺ T cells (left) and CD8⁺ T cells (right). (C) CD38 and HLA-DR cell surface expression on blood CD4⁺ T cells (left) and CD8⁺ T cells (right) using the same gating strategy. The percentage of cells positive for both HLA-DR and CD38 staining is given in the upper quadrant of each dot plot.
