FIG 3.

Correlation between log₁₀ VL set point and frequency of NKG2C⁺ NK cells, mean fluorescence intensity (MFI) of NKG2C expression and fold change in NKG2C MFI over background in cells from HIV⁺ CMV⁺ NKG2C^+/+, NKG2C^+/−, and NKG2C^−/− carriers. Correlations between the frequency (A to D) MFI (E to H) of NKG2C expression and fold change in NKG2C MFI over background (I to K) on NK cells from CMV⁺ PLWH with log₁₀ VL for carriers of all NKG2C genotypes tested (A, E, and I) and stratified by NKG2C^+/+ (B, F, and J), NKG2C^+/− (C, G, and K), and NKG2C^−/− (D and H) genotypes. The number of subjects tested, the correlation coefficients (r), and the P values for each correlation are shown in the top left corner of the graphs.
