Elucidation of the mechanism involved in this inhibition of IgE production shows that epsilon germline transcription is decreased by RA , whereas production of interferon-gamma ( IFN-gamma ) was not enhanced in the presence of RA .
 ( DNA: germline, None) , ( protein: IgE, None) , ( protein: interferon-gamma, None) , ( protein: IFN-gamma, None)
