sCD83 inhibits Bcl2L12 expression to increase the responsiveness of sTh2 cells to apoptosis inducers. Naïve control (NC) mice and AR mice were treated with sCD83 or saline daily for one week. Mononuclear cells were isolated from the airway tissues (nasal mucosa and lungs) and exposed to HDM (5 µg/ml) and cisplatin (25 µM) overnight. The cells were then analyzed by flow cytometry. (A) Gated dot plots show apoptotic cell frequency. (B) Summarized apoptotic cells in panel A. (C-E) Expression of Bcl2L12 in sTh2 cells. WT: Wild type mice (C57BL/6 mice). KO: CD154-deficient mice (C57BL/6 background). Data of bars are presented as mean ± SEM. Each dot in bars present data obtained from one mouse. Each group consists of 6 mice. Statistics: ANOVA (p<0.0001) followed by Bonferroni test.
