inter-, intero-
(Latin: between; among, mutually, together; on the inside, internal)
Although abstracted from the many compounds in which it entered English, the form inter- was not generally considered a living prefix in English until the 1400s.
During the later period of Middle English many words borrowed in the Old and Middle French forms entre-, enter- began to be consciously respelled with Latin inter-; although vestiges of the older French borrowings are found in entertain and enterprise.
The living prefix inter- is now freely added to almost any element in English to create such formations with the meaning of "between" and "among". The words formed by intra- are closely related to this inter- prefix; in fact, they both apparently came from the same Latin source.

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.
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.
