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]
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 ...
Cytokines produced during innate immune responses are among the activators of adaptive immune responses. [33] Antibodies exert additive or synergistic effects with mechanisms of innate immunity. Unstable HbS clusters Band-3, a major integral red cell protein; [ 34 ] antibodies recognize these clusters and accelerate their removal by phagocytic ...
The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants , fungi , prokaryotes , and invertebrates (see Beyond vertebrates ).
An interferon-stimulated gene (ISG) is a gene that can be expressed in response to stimulation by interferon. [1] [2] Interferons bind to receptors on the surface of a cell, initiating protein signaling pathways within the cell. This interaction leads to the expression of a subset of genes involved in the innate immune system response. [1]

Interferon omega-1 serves as cytokines which promote innate immunity against viruses and cancers. They are involved with almost every nucleated cell. [7] There are sixteen sub-types of Interferon type I. Despite having roughly 20%-60% sequence identity, the subtypes each act on IFNAR1 or IFNAR2 subunits of the class two helical cytokine ...
