Abstract

Interferons (IFNs) are glycoproteins with antiviral, immunomodulatory and antiproliferative properties. They are classified on the basis of their acid stability, antigenic properties, stimuli for production and cellular origin. IFN-α and IFN-β are acid-stable and derived from leukocytes and fibroblasts. IFN-γ (immune, type II) is acid-labile and generally derived from T lymphocytes. Elaboration of IFN-γ occurs either after sensitized T lymphocytes are exposed to specific antigen or on induction of T lymphocytes with mitogens1,2. IFN-α and IFN-β have been extensively characterized and much is known about their biochemical properties and gene structure3-11. In contrast, there is relatively little information available regarding the physical and biological properties of human IFN-γ (refs 1, 2, 12-17). Particular interest in IFN-γ derives from in vitro and in vivo studies which indicate that IFN-γ has greater antiproliferative effects on neoplastic cells than IFN-α and IFN-β (refs 18-21). We report here the production and characteristics of IFN-γ elaborated by a unique human T-lymphoblast cell line.
