ABSTRACT
Objectives To establish an experimental model for Th1 typ e shifting and meet the requirements of studying on the mechanisms of some immun omodulators. Methods The levels of cytokines, IL-12, IFN-ice were detected by using ELISA. Sple en cells of the BALB/c mice were incubated under the following conditions with different concentrations of T cell mitogen ConA (1 mg/mL, 0.5 mg/mL, 0.25 mg/mL, 0.125 mg/mL), mononuclear phagocyte system activator LPS (50 mg/mL, 5 mg/mL, 0. 5 mg/mL) or LPS (50 mg/mL, 5 mg/mL, 0.5 mg/mL) combined with 0.25 mg/mL ConA. Re sults LPS could induce the production of IL-12 from spleen cells. The lowest concentration that ConA could induce the measurable production of IFN-rom sp leen cells was 0.25 mg/mL. When different concentrations of LPS were combined wi th 0.25 mg/mL ConA, LPS could accelerate the production of IFN- and positively with that of IL-12. Conclusion LPS combined with ConA can induce the activation of spleen cells from mice towards Th1 type response.
