Research Abstract |
Basophils, accounting for less than 1% of total circulating granulocytes, constitutively express FcεR1, and upon crosslinking of FcεR1-bound IgE with multivalent antigens, immediately release various kinds of effector molecules such as histamine and lipid mediators, and Th2-associated cytokines such as IL-4 and IL-13, causing immediate type hypersensitivity. Furthemore, basophils express IL-18R and IL-33R and very strongly produce IL-4 and IL-13 in response to IL-18 and/or IL-33. We have demonstrated that basophils express MHC class II and CD80/86, have the potential to take-up and process protein antigen (Ag), particularly Ag-IgE complexes, and to present peptide with MHC class II and produce IL-4, revealing that basophils are APC, which selectively induce Th2 cells.
