Interferons (IFNs) appear both locally and systematically early after viral infection and participate in limiting the spread of infection.
They also affect cell differentiation, growth, surface antigen expression and immunoregulation (1).
There are three naturally occurring interferons: alpha, beta and gamma.
IFN-alpha is derived from lymphoblastic tissue and has a number of therapeutic applications in the treatment of various human cancers and diseases of viral origin.
Recombinant IFN-alpha from both natural and synthetic genes binds to a common cell surface receptor and induces antiviral activity in a variety of cell lines.
When binding to discrete cell surface receptors on target cells, IFN-alpha induces rapid changes in Jak/Stat phosphorylation, which initiates the Jak/Stat signaling pathway (2).
IFN-alpha signaling also involves production of DAG without an increased intracellular free calcium concentration and the subsequent activation of calcium-independent isoforms of PKC (beta and epsilon) (3).
All IFN-alpha signaling pathways lead to final alterations of gene expression, which mediate their pleiotropic biologic activities.
IFN-gamma, also known as type II interferon, is produced mainly in activated T lymphocytes and natural killer cells (4) and has broad effects on various cells of the immune system.
Many signaling proteins including IL-2, FGF, and EGF induce the synthesis of IFN-gamma.
