Abstract Members of the Toll/interleukin-1 receptor (TIR) family are of importance for host defense and inflammation. Here we report that the TIR-family member interleukin-33R (IL-33R) cross-activates the receptor tyrosine kinase c-Kit in human and murine mast cells. The IL-33R–induced activation of signal transducer and activator of transcription 3 (STAT3), extracellular signal-regulated kinase 1/2 (Erk1/2), protein kinase B (PKB), and Jun NH2-terminal kinase 1 (JNK1) depends on c-Kit and is required to elicit optimal effector functions. Costimulation with the c-Kit ligand stem cell factor (SCF) is necessary for IL-33–induced cytokine production in primary mast cells. The structural basis for this cross-activation is the complex formation between c-Kit, IL-33R, and IL-1R accessory protein (IL-1RAcP). We found that c-Kit and IL-1RAcP interact constitutively and that IL-33R joins this complex upon ligand binding. Our findings support a model in which signals from seemingly disparate receptors are integrated for full cellular responses.
