For example, in January 2001, the Food and Drug Administration (FDA) approved the use of PEGylated interferon-alpha in the USA; in this formulation, PEGylated interferon-alpha-2b (Pegintron), polyethylene glycol is linked to the interferon molecule to make the interferon last longer in the body.
Interferon regulatory factors (IRF) are proteins which regulate transcription of interferons (see regulation of gene expression). [1] Interferon regulatory factors contain a conserved N-terminal region of about 120 amino acids, which folds into a structure that binds specifically to the IRF-element (IRF-E) motifs, which is located upstream of the interferon genes.

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 ...
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.
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.

Interferon beta-1a (also interferon beta 1-alpha) is a cytokine in the interferon family used to treat multiple sclerosis (MS). [5] It is produced by mammalian cells, while interferon beta-1b is produced in modified E. coli. [6] Some research indicates that interferon injections may result in an 18–38% reduction in the rate of MS relapses. [7]
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.
