Figure Lengend Snippet: Figure 4. Mice with UTX-deficient T cells skew toward systemic type 2 immune responses, with elevations in both effector T-helper 2 CD4þ T cells and type 2-dependent antibody isotypes, independent of allergic sensitization. (A) Representative flow cytometry plots showing splenic CD44þIL-4þ of CD4þTCRβþ Th2 cells. (B) Summary plots showing frequency, absolute number, and mean fluorescence intensity (MFI) of CD4þCD44þ IL-4þ Th2 cells. (C) Representative flow cytometry plots showing splenic CD44þIL-13þ of CD4þTCRβþ Th2 cells. (D) Summary plots showing frequency, absolute number, and mean fluorescence intensity (MFI) of CD4þCD44þ IL-13þ Th2 cells. (E) Representative flow cytometry showing CD4 and GATA3 staining of gated CD3þ T cells in peripheral blood. (F) Summary plots showing frequency, absolute number, and MFI of CD3þCD4þGATA3þ Th2 cells. (G) Total IgE (n ¼ 62 mice), IgG1 (n ¼ 37-42 mice), and IgG2c (n ¼ 29 mice) at baseline in UTXfl/fl and UTX-TCD mice. Data shown in B and D, except MFI, are pooled from 2 independent experiments, n ¼ 8-9 mice per group. MFI values in B and D and data in E and F are representative of 2 independent experiments with n ¼ 5 mice per group. Statistical analysis: Unpaired t-test in B, D, F, and G, comparing UTXfl/fl and UTX-TCD. P < 0.05, P < 0.01, ns, not significant; Th2, T helper 2.
Article Snippet: Total IgG1 was detected using HRP-conjugated goat antimouse IgG1 (Southern Biotech, cat. no.1070-05) and TMB substrate, while total IgE was detected using HRP-conjugated goat anti-mouse IgE (Southern Biotech cat. no.1110-05) and TMB substrate.
