Abstract excerpt
IL-25 promotes type 2 immunity by inducing the expression of Th2-associated cytokines. Although it is known that the IL-25R (IL-17RB) recruits the adaptor protein ACT1, the IL-25R signaling mechanism remains poorly understood. While screening for IL-25R components, we found that IL-25 responses were impaired in Traf4 (-/-) cells. Administering IL-25 to Traf4 (-/-) mice resulted in blunted airway eosinophilia and...
