Stimulation of human tonsillar mononuclear cells with interleukin-4 ( IL-4 ) and interferon-gamma ( IFN-gamma ) rapidly induced the activation of distinct nuclear factors with different mobilities, both of which bind the IL-4 response element ( IL-4RE ) of CD23b promoter as examined by electrophoretic mobility shift assays ( EMSA ).
