Interleukin (IL)-4-independent maintenance of histone modification of the IL-4 gene loci in memory Th2 cells.
Interleukin (IL)-4-induced STAT6 activation and the subsequent up-regulation of GATA3 are crucial for the induction of chromatin remodeling of the Th2 cytokine gene loci as Th2 cells undergo development. This study probes the role of these molecules in the maintenance of memory Th2 cells. IL-4 was not required to maintain the capability for Th2 cytokine production in in vivo generated antigen-s...
متن کاملIL-4 Derived from Non-T Cells Induces Basophil- and IL-3-independent Th2 Immune Responses
How Th2 immunity develops in vivo remains obscure. Basophils have been considered key innate cells producing IL-4, a cytokine essential for Th2 immunity. Increasing evidence suggests that basophils are dispensable for the initiation of Th2 immunity. In this study, we revisited the role of basophils in Th2 immune responses induced by various types of adjuvants. Mice deficient in IL-3 or IL-3 rec...
متن کاملIL-4 enhances IL-10 gene expression in murine Th2 cells in the absence of TCR engagement.
Both IL-4 and IL-10 are regulatory cytokines produced by Th2 cells that can down-regulate cell-mediated immune responses. The studies reported here examine the influence of various cytokines in the regulation of T cell IL-10 production. The results indicate that IL-10 gene expression by TCR transgenic Th2 cells is significantly up-regulated by IL-4 in the absence of TCR signals. IL-4 enhances b...
متن کاملDetection of IL-4, IL-6 and IL-12 Serum Levels in Generalized Aggressive Periodontitis
Background: Periodontitis is a multifactorial chronic inflammatory disease characterized by destruction of tooth-supporting tissues. Environmental and genetic factors as well as the immune system participate in this process. Recent studies have attempted to elucidate the role of cytokine networks involved in periodontal diseases. Objective: To assess and compare the levels of IL-4, IL-6 and IL-...
متن کاملAn interleukin 4 (IL-4)-independent pathway for CD4+ T cell IL-4 production is revealed in IL-4 receptor-deficient mice.
IL-4 receptor alpha chain (IL-4Ralpha)-deficient mice were generated by gene-targeting in BALB/c embryonic stem cells. Mutant mice showed a loss of IL-4 signal transduction and functional activity. The lack of IL-4Ralpha resulted in markedly diminished, but not absent, TH2 responses after infection with the helminthic parasite Nippostrongylus brasiliensis. CD4+, CD62L-high, and CD62L-low T cell...
