| interferon-alpha | <cytokine> One of the type I interferons produced by peripheral blood leukocytes or lymphoblastoid cells when exposed to live or inactivated virus, double-stranded RNA, or bacterial products. It is the major interferon produced by virus-induced leukocyte cultures and, in addition to its pronounced antiviral activity, causes activation of NK cells. It is used experimentally in the treatment of hairy-cell leukaemia. A number of different subtypes exist that are elaborated by leukocytes in response to viral infection or stimulation with double-stranded RNA; IFN-alpha-2A and -2B are protein products made by recombinant DNA techniques and are used as antineoplastic agents. See: interferon-alpha 2a, interferon-alpha 2b Synonym: leukocyte interferon. Pharmacological action: antineoplastic agent, antiviral agent. (20 Sep 2002) |

Pharmacological action: antineoplastic agent, antiviral agents. Chemical name: Interferon-alphaA (human leukocyte protein moiety reduced) (12 Dec 1998) |
| interferon-alpha 2b | <chemical> Interferon alpha 2b (human leukocyte clone hif-sn 206 protein moiety reduced). A type I interferon consisting of 165 amino acid residues with arginine in position 23. This protein is produced by recombinant DNA technology and resembles interferon secreted by leukocytes. It is used extensively as an antiviral or antineoplastic agent. Pharmacological action: antineoplastic agent, antiviral agents. (12 Dec 1998) |
