Interferon alpha-B, also known as IFNA8, belongs to thealpha/beta interferon family. Interferons areproteinsmade and released byhost cellsin response to the presence ofpathogenssuch asviruses,bacteria,parasitesortumorcells. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. They also allow for communication between cells to trigger the protective defenses of theimmune systemthat eradicate pathogens or tumors.Interferons also activate immune cells, such asnatural killer cellsandmacrophages. They increase recognition of infection or tumor cells by up-regulatingantigen presentation toT lymphocytes. They also increase the ability of uninfected host cells to resist new infection by virus. Certain symptoms, such as aching muscles and fever, are related to the production of IFNs during infection. Produced by macrophages, IFN-alpha have antiviral activities.
