PMN-MDSC frequency correlates with the CD14++CD16- monocyte proportion. (A) Gating strategy used to identify monocyte subsets: in the morphological gate (FSC/SSC) we excluded debris gate (A), and morphologically identified monocytes gate (B). In gate B, we selected CD14++CD16, CD14++CD16+, and CD14-CD16++ monocytes. The percentage of monocyte subsets was calculated in the gate (A) Correlation between PMN-MDSC frequency and CD14++CD16 (B), CD14++CD16+ (C), and CD14-CD16++ (D) monocytes from active TB and LTBI subjects. The Spearman test was applied to evaluate correlations. The p <0.05 was considered statistically significant.
