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 encephalomyelitis (EAE).Materials and Methods: EAE was induced in C57BL/6 mice by immunization with myelin oligodendroglial glycoprotein emulsified in complete Freund's adjuvant. The mice were administered intra-peritoneally with ginger extracts or PBS, from day +3 to +30. On day 31, mice were scarified and the expression of IL-12 and TGF-β mRNA in the spinal cord were determined by using real time-PCR. The serum levels of cytokines were measured by ELISA.Results: In PBS-treated EAE mice, the expression of IL-12 P35 and IL-12 P40 mRNA in the CNS and the mean serum levels of IL-12 were significantly higher than those of healthy group (p<0.001). In ginger-treated EAE mice, the expression of IL-12 mRNA and its serum levels were significantly lower as compared to PBS-treated EAE mice. No significant difference was observed between PBS-treated EAE mice and healthy group regarding the expression of TGF-β mRNA. In ginger (300 mg/kg)-treated EAE group, the expression of TGF-β mRNA and its serum levels were significantly higher in comparison to PBS-treated EAE mice (p Conclusion: These results indicated that ginger extract modulates the expression of IL-12 and TGF-β in CNS and serum of EAE mice.}, keywords = {Experimental autoimmune encephalomyelitis,ginger,IL-12,TGF-β,Serum}, url = {https://ajp.mums.ac.ir/article_7002.html}, eprint = {https://ajp.mums.ac.ir/article_7002_50da80e49bdef5d61dd0775c35f6c009.pdf} }
