IL-13 is a critical mediator of allergic asthma and associated airway hyperresponsiveness. IL-13 acts through a receptor complex comprised of IL-13Ralpha1 and IL-4Ralpha subunits with subsequent activation of signal transducer and activator of transcription 6 (STAT6). The IL-13Ralpha2 receptor may act as a decoy receptor. In human airway smooth muscle (HASM) cells, IL-13 enhances cellular proliferation, calcium responses to agonists and induces eotaxin production. We investigated the effects of pre-treatment with IL-4, IL-13 and IFN-gamma on the responses of HASM cells to IL-13.
