1. A protein produced by cells in response to virus infection that inhibits viral replication.
2. A naturally occurring substance that interferes with the ability of viruses to reproduce.

Interferon also boosts the immune system.

There are a number of different interferons. They fall into three main classes: alpha, beta, and gamma.

All are proteins (lymphokines) normally produced by the body in response to infection. The interferons have been synthesized using recombinant DNA technology.

3. Etymology: coined from English interfere + -on, a chemical suffix for "particle"; in 1957, by co-discoverers, Scots virologist, Alick Isaacs and Swiss microbiologist, Jean Lindenmann, at the National Institute for Medical Research in London.

The term, interferon, came into use because the protein, or substance, "interferes" with the reduplication of viruses or virus reproduction.

Representing a family of glycoproteins derived from human cells which normally have 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 interferon-beta are also called type I interferons, interferon-gamma as type II interferons, and they are more normally classified as cytokines.

Situated between (the valleys of) adjacent watercourses.

Between follicles; as, the interfollicular septa (dividing wall or partition) in a lymphatic (vessel) gland.

Existing or carried on between brothers.

Shining between.

1. To mingle, blend, or fuse thoroughly, or to mix two or more things in this way.
2. To intersperse, intermingle, or to permeate with something.
3. To blend or to fuse, one with another.
4. To pour or to pass (something) between, into, or through; to infuse.
