Interferons (IFNs, / ˌ ɪ n t ər ˈ f ɪər ɒ n / IN-tər-FEER-on [1]) are a group of signaling proteins [2] made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.
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 ...
Plasmacytoid dendritic cells (pDCs) are a rare type of immune cell that are known to secrete large quantities of type 1 interferon (IFNs) in response to a viral infection. [1] They circulate in the blood and are found in peripheral lymphoid organs .
Interferon-alpha, an interferon type I, was identified in 1957 as a protein that interfered with viral replication. [5] The activity of interferon-gamma (the sole member of the interferon type II class) was described in 1965; this was the first identified lymphocyte-derived mediator. [6]
Additionally, interferon gamma secreted by these cells seems to be important in downregulating tight junctions in the epithelial barrier. [5] CD8 + T C 1 Cells. These cells generally produce interferon gamma. Interferon gamma and IL-12 promote differentiation toward T C 1 cells. T-bet activation is required for both interferon gamma and ...

Leukocyte interferon is produced predominantly by B lymphocytes. Immune interferon (IFN-gamma ; MIM 147570) is produced ...
A scanning electron microscope image of normal circulating human blood. One can see red blood cells, several knobby white blood cells including lymphocytes, a monocyte, a neutrophil, and many small disc-shape platelets. White blood cells (WBCs) are also known as leukocytes. Most leukocytes differ from other cells of the body in that they are ...
