Interferon beta can be produced by all nucleated cells when they recognize that a virus has invaded them. The most prolific producers of IFN-α and IFN-β are plasmacytoid dendritic cells circulating in the blood. Monocytes and macrophages can also produce large amounts of type I interferons when stimulated by viral molecular patterns. The ...
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 ...
Upon infection, STING from infected cells can sense the presence of nucleic acids from intracellular pathogens, and then induce interferon β and more than 10 forms of interferon α production. Type I interferon produced by infected cells can find and bind to Interferon-alpha/beta receptor of nearby cells to protect cells from local infection.
Type 1 interferon production is strongly correlated with the progression of lupus, and is thought to drive excessive maturation of pDCs and activation of B cells, among many other effects. In patients with lupus, pDC levels in the circulating blood are decreased most of the pDCs have migrated toward the inflamed and affected tissues.
Interferons are a type of protein called a cytokine, which is produced in response to infection. [9] When released, they signal to infected cells and other nearby cells that a pathogen is present. [9] This signal is passed from one cell to another by binding of the interferon to a cell surface receptor on a naïve cell. [10]
IFNAR1 binding to low affinity ligands, such as IFNα subtypes, has been proposed to be the rate-limiting step in the ternary complex formation. [8] Therefore, if membrane levels of IFNAR1 are too low, the binary IFNα-IFNAR2 complex will be unable to recruit it to induce signaling.
Routh writes that he has been reading about the life of founding father Hamilton and “crying” over his death in a duel with former Vice President Aaron Burr.
