Interferon gamma (IFNG or IFN-γ) is a dimerized soluble cytokine that is the only member of the type II class of interferons. [5] The existence of this interferon, which early in its history was known as immune interferon, was described by E. F. Wheelock as a product of human leukocytes stimulated with phytohemagglutinin, and by others as a product of antigen-stimulated lymphocytes. [6]

Interferon-γ (IFN-γ) release assays rely on the fact that T-lymphocytes will release IFN-γ when exposed to specific antigens. These tests are mostly developed for the field of tuberculosis diagnosis , but in theory, may be used in the diagnosis of other diseases that rely on cell-mediated immunity, e.g. cytomegalovirus and leishmaniasis and ...
[80] [81] Gene cloning also confirmed that IFN-α was encoded by a family of many related genes. [82] The type II IFN (IFN-γ) gene was also isolated around this time. [83] Interferon was first synthesized manually at Rockefeller University in the lab of Dr. Bruce Merrifield, using solid phase peptide synthesis, one amino acid at a time. He ...
After this date the shares becomes ex dividend. Ex-dividend date – the day on which shares bought and sold no longer come attached with the right to be paid the most recently declared dividend. In the United States and many European countries, it is typically one trading day before the record date. This is an important date for any company ...
The major subtypes identified are IFN-α1, IFN-α2, IFN-α8, IFN-α10, IFN-α14 and IFN-α21. Of these, IFN-α2 and IFN-α14 are glycosylated. The IFN-α content is expressed in International Units per milliliter, and the drug product is formulated in isotonic phosphate buffer solution at pH = 7.2, and supplemented with human albumin at 1.5
The human interferon-gamma receptor complex consists the heterodimer of two chains: IFNGR1 and IFNGR2. [2] [3] In unstimulated cells, these subunits are not preassociated with each other but rather associate through their intracellular domains with inactive forms of specific Janus family kinases (Jak1 and Jak2).
