Co-stimulation of HDM and STING ligand increased the serum IgE levels. (A) Strategy of HDM- and cGAMP-co-stimulated mice. (B) Total number of cells in BALF collected from the indicated mice. Saline + saline-treated mice: N = 3, cGAMP + saline-treated mice: N = 3, saline + HDM-treated mice: N = 5, and cGAMP + HDM-treated mice: N = 5. (C, left) Dot plots show the percentage of eosinophils (11b+, 11c−, SiglecF+) and neutrophils (11b+, 11c−, Ly6G+) in BALF from stimulated mice. (C, right) These cells were statistically analyzed. Saline + saline-treated mice: N = 3, cGAMP + saline-treated mice: N = 3, and saline + HDM-treated mice: N = 3, and cGAMP + HDM-treated mice: N = 3. (D) The percentage of B cells in BALF from stimulated mice. Saline + HDM-treated mice, N = 7 and cGAMP + HDM-treated mice, N = 6. (E) Total (left) and HDM-specific IgE levels in serum from stimulated mice. Saline + saline-treated mice: N = 3, cGAMP + saline-treated mice: N = 3, saline + HDM-treated mice: N = 8, and cGAMP + HDM-treated mice: N = 8 for total IgE levels. Saline + saline-treated mice: N = 3, cGAMP + saline-treated mice: N = 3, saline + HDM-treated mice: N = 8, and cGAMP + HDM-treated mice: N = 8 for HDM-specific IgE levels. (F) Serum IgE capture assay in the indicated mice. Saline + saline-treated mice: N = 3, cGAMP + saline-treated mice: N = 5, saline + HDM-treated mice: N = 7, and cGAMP + HDM-treated mice: N = 6. Data are presented as the mean ± SD and are representative of three independent experiments. i.t. intratracheally, n.s not significant, Neu neutrophils, Eo eosinophils.
