Figure Lengend Snippet: IL-25 deficiency increases splenic Th1 cells and decreases Tregs and ILC2s. Shown are gating strategies (the graphs show the gating strategy in one Apoe−/−/IL-25−/− mouse) to identify immune cells in the spleen with flow cytometry and the frequencies in the splenic cells. In a and b, the same CD3+CD4+ flow cytometry plot is shown, because it is the same sample from one representative mouse that has been stained for both INF-γ and IL-5. a, to identify Th1 cells, leukocytes were gated as CD3+CD4+IFN-γ+ T cells in the CD3+CD4+ population. Shown is the frequency of Th1 cells in the spleen of Apoe−/− and Apoe−/−/IL-25−/− mice. b, to identify Th2 cells, leukocytes were gated as CD3+CD4+IL-5+ T cells in the CD3+CD4+ population. Shown is the frequency of Th2 cells in the spleen of Apoe−/− and Apoe−/−/IL-25−/− mice. c, to identify Th17 cells, leukocytes were gated as CD3+CD4+IL-17+ T cells in the CD3+CD4+ population. Shown is the frequency of Th17 cells in the spleen of Apoe−/− and Apoe−/−/IL-25−/− mice. d, to identify Tregs, leukocytes were gated as CD3+CD4+CD25+FoxP3+ T cells in the CD3+CD4+ population. Shown is the frequency of Tregs in the spleen of Apoe−/− and Apoe−/−/IL-25−/− mice. e, to identify ILC2s, leukocytes were gated as CD45+, lineage-negative cells (Lin−) expressing IL-17RB, intermediate (int) IL-7ra, and ICOS in the CD45+ population. Shown is the frequency of ILC2s in the spleen of Apoe−/− and Apoe−/−/IL-25−/− mice. Mann–Whitney test was used; n = 10–19 for Apoe−/− and n = 22 for Apoe−/−/IL-25−/− mice; *, p = 0.022; ****, p < 0.0001. Each dot represents one mouse, and the bars show the mean value ± S.D.
Article Snippet: The enriched fraction of cells was next stained with fluorochrome-conjugated antibodies, such as Lin-Streptavidin PE/Cy7, ICOS-PB (clone C398.4A), CD45-APC/Cy7 (clone 30-F11), IL-7ra-FITC (clone SB/199), and IL-17RB-APC (clone 752101, R&D Systems, Abingdon, UK) and analyzed with the use of flow cytometry.
