Although iNKT cells can protect against lung infections by bacteria (17), the activation of iNKT cells by αGalCer caused massive eosinophilia via the production of IL-4, IL-5, and IL-13 in an OVA-induced allergic rhinitis mouse model; such cells could also promote the infiltration of neutrophils via IL-17A production (18–21). Here, IL5 is linked to Increased total eosinophil count.
