BCG infection induced the elevation in the counts of IL-35-producing B cells in the blood and in each immune tissue. PBMCs and mononuclear cells from the lung, spleen, and bone marrow were extracted from BCG-infected mice (n = 6). Then, the cells were assessed for the frequencies of IL-35-producing B cells by flow cytometry. The gating strategy is shown in Figure S2. (A, B, E, F) shows the representative histograms for flow cytometry analysis of the expression of IL-35 in B cells in PBMCs (A) and B cells in mononuclear cells from lung (B), spleen (E), and bone marrow (F) in BCG-infected mice and controls for 4 weeks. (C, D, G, H) shows the graph data showing the mean frequencies of IL-35-producing cells in B cells in PBMCs (C) and in mononuclear cells from the lung (D), spleen (G), and bone marrow (H) in BCG-infected mice (n = 10) for 2, 4, and 8 weeks and controls (n = 6). The P value is shown in each column. *P < 0.05; **P < 0.01; ***P < 0.001.
