IL-4-producing TFH cells decreased in Sting−/− mice. (A,B) The percentage of TFH cells (CD3+, CD4+, CD8α−, CD25−, CD44+, CXCR5+, and PD-1+) in MLNs from the indicated mice. Saline-treated WT mice: N = 3, Sting−/− mice: N = 3, HDM-sensitized WT mice: N = 7, and Sting−/− mice: N = 7. (C) IL-4 in TFH cells from the indicated mice was intracellularly stained and analyzed by flow cytometry. HDM-sensitized WT mice: N = 4, Sting−/− mice: N = 4. Data are presented as the mean ± SD and are representative of two independent experiments. n.s not significant, MLN mediastinal lymph node, MFI median fluorescence intensity.
