Percentages of Natural Killer (NK) cells and their subsets; lytic potential of NK cells. A: Representative dot plot of CD16^lowCD56^bright; CD16⁺CD56^bright, CD16⁺, CD56^dim and CD16^brightCD56^- cells. Based on forward and side scatter analysis, cells were first gated on lymphocytes (not shown) and then on CD3^- cells. B: Absolute numbers of CD4⁺ T-cells (light grey line, number of CD4/mm3), % of CD56^bright in total CD56 NK cells (dark grey line, % of CD56^bright cells) and HIV viral load (black line, number of copies/mL) during one year. C: Representative dot plots of the expression of activating and inhibitory receptors on NK-cells among CD56⁺ CD16^+/− cells. D: Representative dot plots of CD107a degranulation and IFN-γ secretion on CD56^dim and CD56^bright cells, following PBMC activation by K562.
