IL-25 responder and producer cells in aortitis in Il1rn−/− mice. (a) Incidence and severity score of aortitis in Il1rn−/− mice transferred with Il1rn−/− BM cells (n = 13) or Il25−/−Il1rn−/− BM cells (n = 19) and in Il25−/−Il1rn−/− mice transferred with Il1rn−/− BM cells (n = 14) or Il25−/−Il1rn−/− BM cells (n = 5). Data show the mean + SD. *p < 0.05 vs. Il1rn−/− mice transferred with Il1rn−/− BM cells. (b,c) Expression of IL-1β in CD11c+ DCs and (d,e) expression of TNF in Mac2+ macrophages prepared from the aortae of Il1rn−/− mice after IL-25 stimulation. Data show the mean + SD (n = 130 fields; c and e). *p < 0.001 vs medium alone. Scale bars = 20 μm.
