These are alpha and beta also known as.

They are important modulators of the immune response. Interferon is a protein produced by cells in response to a viral infection or certain other agents. Interferons are man-made versions of proteins your body makes.

They are not expressed in normal cells but viral infection of a cell causes interferons to be made and released from the cell that cell will often eventually die as a result of the infection. What diseases can interferon treat. Instead it is a message that is read by human cells.

The interferons IFNs are a large group of proteins defined by their capacity to interfere with viral replication in cells via induction of new mRNA and protein synthesis.

The more recently described type III IFNs IFNλ2 IFNλ3 and IFNλ1 are also known as IL28A IL28B and IL29. Interferons bind to specific receptors on cell membranes. Essentially when confronted with a virus each cell shoots an emergency flare of interferon to tell the immune system to.

This is a type II interferon it is labile at pH 2. Interferon is therefore a critical part of the immune system. Interferon appears to be bodys first line of defense against viral infection and is considered as nonspecific resistance factor because it does not exhibit specificity towards a particular virus.
