Get Beta Interferons #P-23245

Both IFN-α/β and IFN-γ have been shown to be essential for virus control (33). In addition to their direct antiviral properties, IFNs are potent regulators of cell growth and thus indirectly influence virus replication.

The type III group is a group of anti-viral cytokines, that consists of four IFN-λ (lambda) molecules called IFN-λ1, IFN-λ2, IFN-λ3 (also known as IL29, IL28A and IL28B respectively), and IFN-λ4. They were discovered in 2003.

Type I and type II interferons (IFN) are central to both combating virus infection and modulating the antiviral immune response. Indeed, an absence of either the receptor for type I IFNs or IFN-y have resulted in increased susceptibility to virus infection, including increased virus replication and reduced survival.

-beta reduces myeloid dendritic concentrations in peripheral blood. It also alters the function of dendritic cells and other APCs to downregulate antigen presentation and the ability of APCs to stimulate T-cell responses.

Gene group: Interferons (IFN)

Once released, type I interferons bind to specific receptors on target cells, which leads to expression of proteins that will prevent the virus from producing and replicating its RNA and DNA. Overall, IFN-α can be used to treat hepatitis B and C infections, while IFN-β can be used to treat multiple sclerosis.

There are three types of interferons (IFN), alpha, beta and gamma. IFN-alpha is produced in the leukocytes infected with virus, while IFN-beta is from fibroblasts infected with virus. IFN-gamma is induced by the stimulation of sensitized lymphocytes with antigen or non-sensitized lymphocytes with mitogens.
