Abstract:
Objective:To study deeply on the effects of sinomenine on Th1 type cytokines expression of T lymphocytes.Methods:The authors isolated and cultured the mesenteric lymph nodes of mice in vitro.The lymphocytes were stimulated with PDB and inomycin after added sinomenine in different concentrations for 1 hour.After 4 hours stimulation,cells were collected and stained intracellular cytokines with the dying regents,then the expression of Th1 type cytokine IFN-?,pro-inflammatory cytokine TNF-? of T lymphocytes were analyzed by flow cytometry.And also observed the effects of drugs on the expression of CD69,an early marker of T cell activation.Results:1 000 ?mol/L(329.4 ?g/ml)sinomenine can downregulate CD69 expression of T lymphocytes while 200 ?mol/L sinomenie show no effect on it.200,1 000,2 000 ?mol/L sinomenine can obviously reduce the expression of intracellular cytokines such as IFN-?,TNF-? in dose-dependent manner.Conclusion:One of the immunological mechanisms of sinomenine to treat rheumatoid arthritis may due to the inhibitory effects on abnormal T lymphoctytes activation.The inhibitory effects of sinomenine may mainly be relative to the inhibitory effects on Ca 2+ -dependant signal pathway of T lymphocytes activation but not PKC pathway.
