interferon alfa-2a


interferon

 [in″ter-fēr´on] any of a family of glycoprotein modifiers" >biological response modifiers used as antineoplastic agents and immunoregulators; they inhibit cellular growth, alter the state of cellular differentiation, have effects on the cell cycle, interfere with oncogene expression, alter cell surface antigen expression, have effects on antibody production, and regulate cytotoxic effector cells.interferon-α the major interferon produced by virus-induced leukocyte cultures; its primary producer cells are null cells, and its major activities are antiviral activity and activation of NK cells.interferon alfa-2a a synthetic form of interferon-α produced by recombinant technology that acts as a biologic response modifier, used as an antineoplastic in the treatment of hairy cell leukemia and AIDS-related Kaposi's sarcoma; administered intramuscularly or subcutaneously.interferon alfa-2b a synthetic form of interferon-α produced by recombinant technology that acts as a biologic response modifier, used in the treatment of veneral warts, hepatitis B, and chronic hepatitis C and as an antineoplastic in the treatment of hairy cell leukemia, malignant melanoma, non-Hodgkin's lymphomas, multiple myeloma, mycosis fungoides, and AIDS-related Kaposi's sarcoma; administered intramuscularly, subcutaneously, or intralesionally.interferon alfacon-1 a synthetic interferon related to both α and β interferons, produced by recombinant DNA technology; used in the treatment of chronic hepatitis C virus infection, administered subcutaneously.interferon alfa-n3 a highly purified mixture of natural human interferon proteins that acts as a biologic response modifier; used in the treatment of venereal warts, administered intralesionally.interferon-β the major interferon produced by double-stranded RNA-induced fibroblast cultures; the major producer cells are fibroblasts, epithelial cells, and macrophages, and its major activity is antiviral.interferon beta-1a a synthetic form of interferon-β produced by recombinant DNA techniques that acts as a biologic response modifier; used in the treatment of relapsing forms of multiple sclerosis; administered intramuscularly.interferon beta-1b a synthetic modified form of interferon-β produced by recombinant DNA techniques; used as a biologic response modifier in the treatment of relapsing forms of multiple sclerosis; administered subcutaneously.interferon-γ the major interferon produced by lymphocyte cultures that have been immunologically stimulated by mitogens or antigens; the major producer cells are lymphocytes" >T lymphocytes, and its major activity is immunoregulation.interferon gamma-1b a synthetic form of interferon-γ produced by recombinant technology that acts as a biologic response modifier and antineoplastic. It is used to reduce the frequency and severity of serious infections associated with chronic granulomatous disease, administered subcutaneously.

interferon alfa-2a

(ăl′fə-)n. A synthetic form of interferon alpha produced by recombinant DNA technology, used in the treatment of chronic hepatitis C, hairy cell leukemia, and certain types of chronic myelogenous leukemia.
