Abstract
Previous reports have described synergism of various interferon preparations in anticellular and antiviral activity. We report that recombinant interferon (rIFN gamma) and IFN alpha/beta mediate distinct, antagonistic effects on expression of a lectin-like receptor for mannose and fucose (MFR) on mouse peritoneal macrophages (M phi). IFN gamma down-regulates MFR activity, a highly reproducible change in mouse M phi activated to secrete enhanced levels of o-2/H2o2. IFN alpha/beta enhances MFR activity and prevents the action of IFN gamma when added in combination. Antagonism is selective for this M phi activation marker and requires a minimum 4 h exposure period to rIFN gamma, during which IFN alpha/beta can prevent its action.Entities:
