Interferons: Mechanism of Action
Interferons (IFN-α, IFN-β, IFN-γ) are a part of innate host defense. They interfere with both RNA and DNA viruses. Cells infected with a virus synthesize these glycoproteins, which then act on local cells, priming them for viral defense by downregulating protein synthesis to resist potential viral replication and by upregulating MHC expression to facilitate recognition of infected cells. Interferons also play a major role in activating antitumor immunity.
