IFNβ exposure rescues dendritic cell GITRL downregulation from low-dose LPS pre-exposure. (A) Surface GITRL expression on primary CD11c+CD11b+ dendritic cells by flow cytometry. (B) Membrane-fraction immunoblotting of GITRL expression on primary CD11c+CD11b+ dendritic cells. (C) Flow cytometry of surface GITRL expression on lung-derived CD11c+CD11b+ dendritic cells. (D) Membrane-fraction immunoblotting of GITRL expression in lung-derived CD11c+CD11b+ dendritic cells. Data are reported as means ± standard deviations (SDs). **p < 0.01 and ***p < 0.001 vs. Control group; #p < 0.05, ##p < 0.01, and ###p < 0.001 vs. PBS/OVA group. Control, unexposed normal mice; PBS/OVA, asthmatic mice; 3d1μgLPS/OVA, low-dose (1 μg daily) LPS-exposed asthmatic mice with LPS exposure at 3rd DOL; 3d1μgLPS/PBS, low-dose (1 μg daily) LPS-exposed normal mice with LPS exposure at 3rd DOL.
