Influences of protein kinase C inhibitors on the expression of IL-2 and IFN-?by human T-lymphocytes / 中国病理生理杂志

ABSTRACT

AIM: To investigate the influences of protein kinase C(PKC) inhibitors on the expression of interleukin-2(IL-2) and interferon-?(IFN-?) by in vitro activated T-lymphocytes. METHODS: Double fluorescent staining together with flow cytometry was adopted to detect intracellular cytokines and to analyze the effects of H7 and gossypol on IL-2 and IFN-? expression levels of T-lymphocytes stimulated with phorbol ester (PDB)+ionomycin(I) in the presence of monensin.RESULTS: The expression rates of IL-2 and IFN-? of CD3 + T cells stimulated with PDB+I for 4 h were 16.64?2.04 and 25.81?3.53( ?s ), respectively, which were significantly higher than that of control (1.06?0.22 and 3.12?0.77)( P
