Recombinant Interferon Gamma
Definition 1
A recombinant therapeutic agent which is chemically identical to or similar to the endogenous lymphokine interferon gamma (IFN-gamma) with antineoplastic, immunoregulatory, and antiviral activities. Therapeutic IFN-gamma binds to and activates the cell-surface IFN-gamma receptor, stimulating antibody-dependent cytotoxicity and enhances natural killer cell attachment to tumor cells. This agent also activates caspases, thereby inducing apoptosis in malignant cells. (NCI Thesaurus)
Definition 2
The major interferon produced by mitogenically or antigenically stimulated lymphocytes. It is structurally different from type I interferon (INTERFERON TYPE I) 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. (NLM, Medical Subject Headings)
Definition 3
activates NK cells, cytotoxic T cells, endothelial cells, and macrophages; stimulates LAK activity; costimulates B cell proliferation; inhibits T cell proliferation; implicated in aberrant expression of MHC II antigens leading to autoimmune disease. (NIH CRISP Thesaurus)
