ABSTRACT
Objective:To explore the effect of the synthetic immunomodulator CH 2b with a thiazolidin-4-one ring on the pathogenesis of rheumatoid arthritis (RA) mice induced by glucose-6-phosphate isomerase(GPI) mixed peptides.Methods:hGPI325-339 ,hGPI469-483 peptide fragments were mixed with complete freund′s adjuvant fully ,DBA/1 mice were givien subcutaneous injection of the emulsifiers,pertussis toxin to strengthen immunity.And then RA mice were intervened with α-GalCer and CH2b,the changes of body weight ,ankle joint symptoms scores were observed .The joint tissues stained with hematoxylin and eosin ( HE) was used to evaluate the inflammatory cells.Fluorescence-activated cell sorting ( FACS) was used to detect the frequency changes of iNKT cells .Cytometric bead array(CBA) was used to analyze the levels of serum cytokines TNF-α,IL-6,IL-4,IFN-γ.Results: Compared with the model group,α-GalCer,CH2b could reduce the inflammation of the model mice ,significantly improve the body weight growth and the joint swelling(P0.05).Conclusion:Immunomodulator CH2b by activating iNKT cells affect the secretion of inflammatory cytokines ,and it relieved the GPI induced arthritis .
