Abstract:
Objective:To investigate the effects of sinomenine(SIN)on the activation and function of T-cells from SLE patients and to elucidate the mechanisms for the immunosuppressive effect of SIN.Methods:PBMCs were isolated from SLE patients and stimulated with anti-CD3 in the presence or absence of different concentrations of SIN.The cytokines were measured by ELISIA,and the activation and function of T-cells were analyzed by flow cytometry.Results:SIN could inhibit IFN-?,IL-2 and IL-4 production of T cells in SLE patients' peripheral blood.In addition,SIN could significantly inhibit the expression of activation molecules CD69 and CD25 by CD4+ and CD8+ T cells.Conclusion:SIN could inhibit immune responses of SLE patients by suppressing T cells activation and cytokine secretion.
