Fig. 3. Frequency and distribution of CD32⁺ cells are similar between blood and tonsils of ART-treated HIV⁺ donors.

(A) Distribution of CD32⁺ HLA-DR-within cell subsets in tonsil samples from ART-treated HIV⁺ donors. (B) Frequencies of T_H subsets within memory CD32⁺ CD4⁺ T cells. Not subset refers to those cells that did not fall into the defined Th subsets. (C and D) Frequency of CD38⁺ (C) and Ki67⁺ (D) cells in CD32/HLA⁻ DR-expressing memory CD4⁺ T cells. Representative examples are shown for each marker with overlaid plots showing CD32⁺ cells (red dots in plots and solid red lines in histograms) over total memory cells (black dots in plots and dotted lines in histograms). (E) Heat map showing the frequency of all measured phenotypic markers in CD32⁺ and CD32⁻ cells. In all graphs, a line indicates the median of the group. All data were analyzed using a Friedman test (paired, nonparametric) and corrected for multiple comparisons with Dunnett’s posttest. *P < 0.05; n = 4.
