Ginger extract modulates the expression of IL-12 and TGF-β in the central nervous system and serum of mice with experimental autoimmune encephalomyelitis
Objective: The main function of IL-12 is differentiation of naive T cells intoTh1 cells and TGF-β is a powerful immunoregulatory cytokine. The immunomodulatory and anti-inflammatory properties of ginger have also been reported in some studies. The aim of this study was to evaluate the effects of ginger extract on the expression of IL-12 and TGF-β in a model of experimental autoimmune encephalom...
متن کاملEarly growth response gene-2 controls IL-17 expression and Th17 differentiation by negatively regulating Batf.
Early growth response gene (Egr)-2 is important for the maintenance of T cell homeostasis and controls the development of autoimmune disease. However, the underlying mechanisms are unknown. We have now discovered that Egr-2, which is induced by TGF-β and IL-6, negatively regulates the expression of IL-17, but not IL-2 or IFN-γ, in effector T cells. In the absence of Egr-2, CD4 T cells produce h...

Background: Recent studies have demonstrated an essential role for IL-17 in the pathogenesis of experimental autoimmune encephalomyelitis (EAE). Furthermore, it has been shown that FoxP3+Treg cells play an important role in the suppression of autoinflammatory reactions. Although, previous studies have determined the immunomodulatory potentials of all-trans-retinoic acid (ATRA), but these immuno...
متن کاملIL-25 regulates Th17 function in autoimmune inflammation
Interleukin (IL)-25 is a member of the IL-17 family of cytokines. However, unlike the other members of this family, IL-25 promotes T helper (Th) 2 responses. We now show that IL-25 also regulates the development of autoimmune inflammation mediated by IL-17-producing T cells. We have generated IL-25-deficient (il25-/-) mice and found that they are highly susceptible to experimental autoimmune en...
متن کاملGinger Extract Reduces the Expression of IL-17 and IL-23 in the Seraand Central Nervous System of EAEMice
Background: IL-17/IL-23 axis plays an important role in the pathogenesis of several autoimmune diseases such as experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS). The immunomodulatory properties of ginger are reported in previous studies. Objective: To evaluate the effects of ginger extract on the expression of IL-17 and IL-23 in a model of EAE. Methods: EAE was induc...
