Interferon

Interferon

(Science: cytokine) a family of glycoproteins derived from human cells which normally has a role in fighting viral infections by preventing virus multiplication in cells.

They are secreted by vertebrate cells in response to a wide variety of inducers and confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions.

interferon-alpha is made by leucocytes and interferon-gamma by fibroblasts after viral infection. Interferon-alpha and -beta are also called type i interferons, interferon-gamma as type II interferons, more usually classed as cytokines.

Pharmacological action: antineoplastic agent, antiviral agents. An antiviral protein produced by cells that have been invaded by a virus; inhibits replication of the virus.A type of glycoprotein that is produced as a defense mechanism against [[pathogens.

Prednisone stimulates Th1 but enhances th2 when discontinued

Prednisone blocks il-4 and il-10 thus increasing interferon gamma, an integral part of th1. But after it is discontinued, the il-4 and il-10 are worse than before the prednisone was started. Why is this?
