Interferon alfacon-1
|
Interferon alfacon-1 is a recombinant non-naturally occurring type-I interferon. The 166-amino acid sequence of Interferon alfacon-1 was derived by scanning the sequences of several natural interferon alpha subtypes and assigning the most frequently observed amino acid in each corresponding position. Four additional amino acid changes were made to facilitate the molecular construction, and a corresponding synthetic DNA sequence was constructed using chemical synthesis methodology. Interferon alfacon-1 differs from interferon alfa-2b at 20/166 amino acids (88% homology), and comparison with interferon-beta shows identity at over 30% of the amino acid positions. Interferon alfacon-1 is produced in Escherichia coli (E. coli) cells that have been genetically altered by insertion of a synthetically constructed sequence that codes for Interferon alfacon-1. Prior to final purification, Interferon alfacon-1 is allowed to oxidize to its native state, and its final purity is achieved by sequential passage over a series of chromatography columns. This protein has a molecular weight of 19,434 daltons. Pharmacology: Upregulates the expression of MHC I proteins, allowing for increased presentation of peptides derived from viral antigens. This enhances the activation of CD8+ T cells that are the precursors for cytotoxic T lymphocytes (CTLs) 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 (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. Drug type: Approved. Biotech. Drug category: Antineoplastic Agents. Antiviral Agents. Immunomodulatory Agents

Interferon gamma-1b
|
Human Interferon gamma-1b (140 residues), produced from E. coli. Production of Actimmune is achieved by fermentation of a genetically engineered Escherichia coli bacterium containing the DNA which encodes for the human protein. Purification of the product is achieved by conventional column chromatography. Pharmacology: IFN gamma stimulates expression of the immunoglobulin heavy chain C gamma 3 and C gamma 2a germline transcripts in B cells. Many components of the antigen presentation pathways are also up-regulated by interferon gamma. It is also a potent activator of macrophages, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of type I interferons. Interferon gamma may also help the body regulate the activity of fibroblasts. By directly blocking the multiplication of fibroblasts and inhibiting the production and action of TGF-b, a potent scar-inducing molecule, Interferon gamma-1b may prevent excessive scarring. Mechanism of action: Binds directly to the type II interferon gamma receptor IFNGR1, leading to a complex of IFNGR1 and IFNGR2. This activates JAK1 and JAK2 kinases which form a STAT1 docking site. This leads to STAT1 phosphorylation, nuclear translocation and initiation of gene transcription of multiple immune-related genes. Drug type: Approved. Biotech. Investigational. Drug category: Antiviral Agents. Immunomodulatory Agents

Interleukin
|
A group of cytokines (secreted proteins/signaling molecules) that were first seen to be expressed by white blood cells (leukocytes), The term interleukine, (inter-) as a means of communication, (-leukin) deriving from the fact that many of these proteins are produced by leukocytes and act on leukocytes. The name is something of a relic though (the term was coined by Dr. Paetkau, University of Victoria); it has since been found that interleukins are produced by a wide variety of body cells. The function of the immune system depends in a large part on interleukins, and rare deficiencies of a number of them have been described, all featuring autoimmune diseases or immune deficiency. The majority of interleukins are synthesized by helper CD4+ T lymphocytes, as well as through monocytes, macrophages, and endothelial cells. (Adapted from Wikipedia)

Interleukin-1
|
A soluble factor produced by monocytes, macrophages, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. IL-1 consists of two distinct forms, IL-1 alpha and IL-1 beta which perform the same functions but are distinct proteins. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation. The factor is distinct from INTERLEUKIN-2 (MSH).

Intermediate filament
|
A cytoskeletal structure that forms a distinct elongated structure, characteristically 10 nm in diameter, that occurs in the cytoplasm of eukaryotic cells. Intermediate filaments form a fibrous system, composed of chemically heterogeneous subunits and involved in mechanically integrating the various components of the cytoplasmic space. Intermediate filaments may be divided into five chemically distinct classes: Type I, acidic keratins; Type II, basic keratins; Type III, including desmin, vimentin and others; Type IV, neurofilaments and related filaments; and Type V, lamins.
