The family of interferons (IFNs) are glycoprotein proteins that have a wide range of biological activity, including antiviral, antitumor, and also exhibit antiproliferative and proapoptotic properties. There are three known types of interferons: type I IFN / type I IFN (α, β, ω, τ, κ, ˜, and δ), type II IFN / type II IFN (γ), and type III IFN / type III IFN (λ1 (IL-29), λ2 (IL-28A), λ3 (IL-28B)). The classification of interferons by type is based on their interaction with the corresponding cellular receptors. Type I and II IFN receptors are present on the surface of most human cells, while type III IFN receptors are highly expressed on hepatocytes, but absent on the surface of microvascular endothelial cells, adipocytes, fibroblasts, and cells of the central nervous system.
