Fig. 2. Myelomonocytic cells increase in BAL is associated with IL-6.
a Decrease of alveolar macrophages (defined as HLA-DR+ CD206+ CD163+ cells) in the BAL after infection. b Increase in the frequency of myelomonocytic infiltrates (defined as HLA-DR+ CD206− CD163−) and c of endothelial cells (defined as HLA-DR+ CD206− CD163+) at infection in BAL (1wk pi). For figure a–c, n = 7, 4, 8, 4 for baseline weeks 1, 2, and 3 time points, respectively, and analyzed by the Kruskal–Wallis test, Dunn’s multiple comparison test. The bars represent mean and standard error. d tSNE plots displaying kinetics of expression of CD16, CD11b, and CD11c markers on live/ HLA-DR+ cells populations in BAL before and after infection. e Gating of CD11c+ and CD11b+ populations on the tSNE map based on antigen expression and discrete density clustering. f Characterization of populations shown in e. The heatmap depicts the fold-change values of each antigen compared to the channel values of negative-expressing cell populations. g Increase in the percentage of CD16+ HLA-DR+ cells and h in the percentage of interstitial macrophages (CD16+ CD206− HLA-DR+) expressing of CD11c and i CD11b in BAL overtime (baseline n = 8, week 1 n = 4, week 2 and 3 n = 7; Kruskal–Wallis test, Dunn’s multiple comparisons).
