[The effect of cytokines on the activation of T cells induced by B7-1-transfected leukemia cells].
OBJECTIVE
To observe the effects of IL-12, IFN-gamma, IL-10 on the B7-1 expression of B7-1 transfected leukemia cells (K562 and HL-60) and on the IL-2 and IFN-gamma expression and production in the peripheral blood mononuclear cells(PBMC) induced by B7-1 transfected K562 and HL-60 cells.


METHODS
RT-PCR and ELISA techniques were used to assay the expression and production of IFN-gamma and IL-2.


RESULTS
IFN-gamma and IL-12 increased the expressions of B7-1, IL-2 and IFN-gamma, but IL-10 inhibited all the expressions.


CONCLUSIONS
IFN-gamma, IL-10 and IL-12 affected the expression and production of IFN-gamma and IL-2 possibly by affecting the B7-1 expression.
