Recombinant Human Interferon: IFNgamma is the major interferon produced by mitogenically or antigenically stimulated lymphocytes. It is structurally different from type I interferon and its major activity is immunoregulation. It has been implicated in the expression of class II histocompatibility antigens in cells that do not normally produce them, leading to autoimmune disease. Interferon gamma is produced mainly by T-cells and natural killer cells activated by antigens, mitogens, or alloantigens. It is produced by lymphocytes expressing the surface antigens CD4 and CD8. IFNgamma synthesis is induced by IL-2, FGF-basic, and EGF.Alternative Names: Recombinant Human Interferon, Interferon Gamma, IFN-Gamma, Immune Interferon, IFNG
