When used with the antiviral drug ribavirin, PEGylated interferon is effective in treatment of hepatitis C; at least 75% of people with hepatitis C genotypes 2 or 3 benefit from interferon treatment, although this is effective in less than 50% of people infected with genotype 1 (the more common form of hepatitis C virus in both the U.S. and ...
Interferon alfa-2b is an antiviral or antineoplastic drug. It is a recombinant form of the protein Interferon alpha-2 that was originally sequenced and produced recombinantly in E. coli [1] in the laboratory of Charles Weissmann at the University of Zurich, in 1980.
Interferon alfa or HuIFN-alpha-Le, trade name Multiferon, is a pharmaceutical drug composed of natural interferon alpha (IFN-α), obtained from the leukocyte fraction of human blood following induction with Sendai virus. Interferon alfa contains several naturally occurring IFN-α subtypes and is purified by affinity chromatography.
Taribavirin, however, has useful properties of less erythrocyte-trapping and better liver-targeting than ribavirin. The first property is due to taribavirin's basic amidine group which inhibits drug entry into RBCs, and the second property is probably due to increased concentration of the enzymes which convert amidine to amide in liver tissue.

Intracerebroventricular injection has also been used to test therapeutics and other drugs in animals. Examples of these studies include injection of bromodeoxyuridine for proliferation tracing, Apelin-13 for cerebral ischemia, and α-interferon for its antiviral and antibiotic properties.
Pegylated interferon alfa-2a is in the alpha interferon family of medications. [3] It is pegylated to protect the molecule from breakdown. [6] Pegylated interferon alfa-2a was approved for medical use in the United States in 2002. [3] It is on the World Health Organization's List of Essential Medicines. [7]
Interferon beta is a protein that in humans is encoded by the IFNB1 gene. [5] The natural and recombinant protein forms have antiviral, antibacterial, and anticancer properties. Interferon beta 1a (tradenames: Avonex and Rebif) and Interferon beta 1b (tradenames: Betaseron/Betaferon) are used as drugs.
The type-I interferons (IFN) are cytokines which play essential roles in inflammation, immunoregulation, tumor cells recognition, and T-cell responses. In the human genome, a cluster of thirteen functional IFN genes is located at the 9p21.3 cytoband over approximately 400 kb including coding genes for IFNα (IFNA1, IFNA2, IFNA4, IFNA5, IFNA6, IFNA7, IFNA8, IFNA10, IFNA13, IFNA14, IFNA16 ...
