al. showed that the production of IL‐5 and IL‐13, eosinophilia, mucous production and airway hyper‐responsiveness (AHR) induced by administration of IL‐25 to the airways was independent of T cells and IL‐4 9, while Sharkhuu and colleagues reported that IL‐25 induced IL‐4 as well as IL‐5 and IL‐13 from naïve murine T cells 10. The gene discussed is IL25; the disease is Increased total eosinophil count.
