NCIt definition : A recombinant form of the endogenous cytokine human interferon (IFN) gamma-1b, with
immunomodulating activity. Upon administration, IFN gamma-1b targets, binds to, and
activates the cell-surface IFN-gamma receptor, stimulating antibody dependent cellular
cytotoxicity (ADCC), activating natural killer (NK) cells, and enhancing the oxidative
metabolism of macrophages. IFN-gamma plays important roles in the innate and adaptive
immune responses.;
