Background: Fungal aeroallergens might sensitize the airway which in turn produces a specific cytokine profile. Objective: To evaluate the IL-25 and IL-33 profile in patients with fungal allergic rhinitis. Methods: The present study examined patients who were evaluated due to allergic rhinitis (AR) at Emam Reza Hospital of Shiraz, Iran. The all...

The role of the innate immune system in asthma initiation is being increasingly recognised, and several innate epithelial cytokines, such as interleukin 33 (IL-33), IL-25 and thymic stromal lymphopoietin, have been described as important in asthma pathogenesis. However, until now, the mechanism by which these cytokines initiate Th2 responses and form a link with the adaptive immune system was u...

IL-25, a member of the IL-17 cytokine family, is known to enhance Th2-like responses associated with increased serum levels of IgE, IgG1, IgA, blood eosinophilia, and eosinophilic infiltrates in various tissues. However, IL-25 also abrogates inflammatory responses driven by Th17 cells. However, the cell types that respond to IL-25 and the mechanisms by which IL-25 differentially regulates immun...
