Asthma and allergic rhinitis are almost invariable accompanied by elevated levels of immunoglobin E (IgE), and more importantly a genetic link between IgE levels and airway hyper-responsiveness has been established. We hypothesized that expression of soluble receptors directed against interleukin (IL)-13 and IL-17e would prevent the cytokines from engaging the cell-bound receptors and therefore help to attenuate allergic responses in a Cftr(-/-)-dependent mouse model of exaggerated-IgE responses. Cftr(-/-) mice were injected with recombinant adeno-associated virus 1 (rAAV1) intramuscularly expressing soluble receptors to IL-17e (IL-17Rh1fc) or IL-13 (IL-13Ralpha2Fc). Total IgE levels, in mice receiving the IL-17Rh1fc and IL-13Ralpha2Fc therapy, were lower …
