Differential CGD genotype–driven host immune responses at the intestinal barrier. Multicolor flow cytometry analysis of WT, gp91phox–/–, and p47phox–/– mice from IRCM before and after DSS treatment showing IgA, IgM, or IgG-coated bacteria (SYBR+) from mouse fecal pellets and fold change relative to WT (bar graph) (A); colon LP frequencies of IgA+ and IgG+ ASCs (CD138+) (B); Treg (FoxP3+), Th17 (RORγT+), and Th1 (T-bet+) CD4+ T cells (C); and frequencies of IL-10+, IL-1β+, myeloid cells (CD11b+, TCRb–), macrophages (F4/80+), DCs (MHCII+, CD11c+), monocytes (Ly6C+), and neutrophils (Ly6G+) (D). (E) Measurements of IFN-γ, TNF-ɑ, IL-2, and IL-10 levels in sera from WT, gp91phox–/–, and p47phox–/– mice from IRCM at baseline and after DSS treatment. The data are presented as means ± standard error of the means. All baseline data are from 1 experiment (n = 3-4 mice per group) and all DSS data are representative of 2 independent experiments (n = 3-4 mice per group). Significance was determined using 1-way and 2-way ANOVA with Holm-Šídák multiple comparison test (∗P < .05; ∗∗P < .01; ∗∗∗P < .001; ∗∗∗∗P < .0001). Freq, frequency; TNF, tumor necrosis factor; Treg, regulatory T cell.
