متن کاملThe role of interleukin-33 in chronic allergic conjunctivitis.
PURPOSE The authors discovered a genetic association between the ST2L gene and atopy. The ST2L gene encodes a membrane-bound functional marker for Th2 cells. Recently, a novel Th2 cytokine, interleukin-33 (IL-33), was discovered to be a specific ligand for ST2L. The authors investigated the role of IL-33 in chronic allergic conjunctivitis. METHODS Immunohistochemical analysis was carried out ...
