بررسی ارتباط پلی مورفیسم ژن IL-4R با شدت پریودنتیت مزمن
Introduction & Objective: Periodontitis is a multifactorial disease in which host immune system and genetic factors have an important role in its pathogenesis. Genetic polymorphisms in cytokines and their receptors have been proposed as potential markers for periodontal diseases. The aim of the present study was to evaluate whether IL-4R gene polymorphism is associated with chronic periodonti...
متن کاملMolecular Characterization and Functional Analysis of Murine Interleukin 4 Receptor Allotypes
The murine interleukin 4 receptor (IL-4R) exists as a transmembrane protein transducing pleiotropic IL-4 functions, or as soluble (s)IL-4-binding molecule with potent immunoregulatory effects. In this study we identified and characterized a murine IL-4R allotype. Sequence analysis of the IL-4R cDNA of BALB/c mice revealed 18 base substitutions leading to three extracellular and five cytoplasmic...
متن کاملAn atopy-associated polymorphism in the ectodomain of the IL-4R(alpha) chain (V50) regulates the persistence of STAT6 phosphorylation.
Several commonly occurring polymorphisms in the IL-4R(alpha) have been associated with atopy in humans; the Q576R and the S503P polymorphisms reside in the cytoplasmic domain, whereas the I50 to V50 polymorphism resides in the extracellular domain of the IL-4R(alpha). The effects of these polymorphisms on signaling remain controversial. To determine the effect of the polymorphisms on IL-4 signa...
متن کاملIL-4R(alpha), a new member that associates with Syk kinase: implication in IL-4-induced human neutrophil functions.
Although Syk has been reported to be associated with IL-2R beta [corrected] and IL-15R alpha in some hematopoietic cells, its association has never been investigated in the IL-4/IL-4R system. In this study, we demonstrate for the first time that Syk is constitutively associated with IL-4R(alpha)in human polymorphonuclear neutrophils (PMNs) and that IL-4 stimulation increases the amount of Syk a...
متن کاملInternalization Property of Interleukin-4 Receptor Chain Increases Cytotoxic Effect of Interleukin-4 Receptor- targeted Cytotoxin in Cancer Cells
Although the receptor for interleukin-4 (IL-4R) is highly expressed on solid human cancer cells, its significance and internalization function is still unclear. To address these issues, we reconstituted Chinese hamster ovarian (CHO-K1) cells with various components of the IL-4R by transient transfection and performed internalization assays using radiolabeled IL-4. Radiolabeled IL-4 internalized...
