| Description | Purified, natural and glycosylated human interferon alpha proteins of 166 residues. |
| Indication/Disease | Used to treat venereal or genital warts caused by the Human Papiloma Virus. |
| Pharmacodynamics | Upregulates the expression of MHC I proteins, allowing increased presentation of peptides derived from viral antigens. This enhances the activation of CD8+ T cells that are the precursors for cytotoxic T lymphocytes and makes the macrophage a better target for CTL-mediated killing. Interferon alpha also induce the synthesis of several key antiviral mediators, including 2-5-oligoadenylate synthetase (2'-5' A synthetase) and protein kinase R. |
| Mechanism of Action | Interferon alpha binds to type I interferon receptors namely IFNAR1 and IFNAR2c which, upon dimerization, activate two Jak (Janus kinase) tyrosine kinases (Jak1 and Tyk2). These transphosphorylate themselves and phosphorylate the receptors. The phosphorylated INFAR receptors then bind to Stat1 and Stat2 (signal transducers and activators of transcription)which dimerize and activate multiple (~100) immunomodulatory and antiviral proteins. Interferon alpha binds less stably to type I interferon receptors than interferon beta. |
