Expression and density (MFI) of CCR2 on patient monocytes at baseline and after ART initiation compared to values among controls.

<p>Values for frequency and density of CCR2 on monocyte subsets in untreated HIV-1 infection were compared to levels among controls using Mann Whitney U tests, and baseline values among patients were compared to values after ART initiation using GEE and Signed Rank test (see boxed legend). Figures show boxplots of medians and interquartile ranges; outliers are shown as open circles. Tukey boxplots show the proportion of CCR2+ total monocytes (A), traditional monocytes (C), inflammatory monocytes (E), and patrolling monocytes (G) in control samples (red) and in patient samples at baseline and after ART initiation. Tukey boxplots show the density of CCR2 on total monocytes (B), traditional monocytes (D), inflammatory monocytes (F), and patrolling monocytes (H) in control samples (red) and in patient samples at baseline and after ART initiation.
