Alick Isaacs

From Wikipedia, the free encyclopedia

Alick Isaacs (17 July 1921 - 26 January 1967) was a British virologist. He is best remembered for his work on interferon, having been Head of the Laboratory for Research on Interferon, National Institute for Medical Research,1964-7.

He was elected a Fellow of the Royal Society in 1966, shortly before his death.

Isaacs, Alick (1921–1967) Scottish virologist who, with Swiss colleague Jean Lindemann, in 1957 discovered interferon, a naturally occurring antiviral substance produced by cells infected with viruses. The full implications of this discovery are still being investigated.

Isaacs was born and educated in Glasgow. From 1951 he worked at the World Influenza Centre, London, becoming its director in 1961.

Isaacs began in 1947 studying different strains of the influenza virus and the body's response to them. Working with Lindemann, he eventually found that when a virus invades a cell, the cell produces interferon, which then induces uninfected cells to make a protein that prevents the virus from multiplying. Almost any cell in the body can make interferon, which seems to act as the first line of defence against viral pathogens, because it is produced very quickly (interferon production starts within hours of infection whereas antibody production takes several days) and is thought to trigger other defence mechanisms.
