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.
Pegylated interferon alfa-2b is a drug used to treat melanoma, as an adjuvant therapy to surgery. [3] Also used to treat hepatitis C (typically, in combination with ribavarin), it is no longer recommended due to poor efficacy and adverse side-effects. [4] Subcutaneous injection is the preferred delivery method. [3]
It took another fifteen to twenty years, using somatic cell genetics, to show that the interferon action gene and interferon gene reside in different human chromosomes. [71] [72] [73] The purification of human beta interferon did not occur until 1977. Y.H. Tan and his co-workers purified and produced biologically active, radio-labeled human ...
The receptor and interferon are taken inside the cell while bound to initiate expression of ISGs. [10] Interferon activation of ISGs uses the JAK-STAT signaling pathway to induce transcription of ISGs. ISGs can be divided based on what class of interferon they are activated by: type I, type II, or type III interferon. [1]
At first, Dan Orlovsky was not impressed. The ESPN analyst removed the virtual-reality headset from his face and told Andrew Hawkins, the ex-NFL wideout who also works for ESPN and is an ...
Washington failed on a 2-point conversion with nine seconds remaining in regulation and lost the Sun Bowl 35–34 to Louisville on Tuesday. The Huskies scored a touchdown on fourth-and-1 on a fade ...
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 ...
