Fig. 4: Core Ba-wt LPS-dependent sustained recruitment of PD-L1⁺Sca-1⁺ macrophages, monocytes and neutrophils in the omentum.

a Omentum and peritoneal fluid were harvested at indicated time-points after i.p. challenge with Ba-wt (red circles), Ba-wadC (cyan circles) or Ec LPS (blue circles), or mock-PBS injection (black circles), and individualized cells analyzed by flow cytometry. Kinetics of omental and peritoneal F4/80^hiMHCII⁺TIM4⁺ macrophages, Ly6C^hiCCR2⁺ monocytes, and Ly6G⁺ neutrophils are shown at indicated time points. Each symbol represents one animal. Mean ± SD from pooled data of normalized absolute numbers. (PBS, 2-3 mice; each LPS, 3-4 mice), n = 3. Significant differences are shown. Kruskal-Wallis followed by Dunn’s multiple comparison test. Absence of p-value, non-significant. b Absolute numbers of omental PD-L1⁺Sca-1⁺ macrophages, monocytes and neutrophils obtained as in (a), with each symbol representing one animal at 48 h post-challenge. (PBS, 2-3 mice; each LPS, 3-4 mice), n = 3. Significant differences are shown (Kruskal-Wallis, followed by Dunn’s multiple comparison test). Absence of p-value, non-significant.
