...vertebrate animals. It was discovered in 1957 in Britain by Virologists Alick Isaacs and Jean Lindenmann during their investigation of a curious phenomenon: people are almost never infected by more than one virus at a time. Seeking an explanation, the researchers infected cells from chick embryos with influenza virus. What they found was a substance that protected the chick cells from both the flu and other viruses. Because it interfered with the infection process, it was dubbed interferon...
...idyl could not last. Father was called to a grimy industrial parish in Birmingham; their mother contracted influenza and died. But soon there was a new Mrs. Knox, an elegant lady from a landed family who encouraged the boys' brilliance: Ronnie was reading Virgil at the age of six. It was she who decreed the boarding schools they later attended: Eton for Dilly and Ronnie, Rugby for Eddie and Wilfred. Dilly went on to Cambridge, where Lytton Strachey fell in love with him (the compliment was not returned). The others went up to Oxford...
Relatively few students have visited University Health Services here this past week and although many students have had viral respiratory illnesses, few actual cases of influenza have turned up, Dr. Sholem Postel, acting director of UHS, said yesterday...
Postel said influenza can be caused by different strains of viruses, such as Hong Kong. Swine or Russian. These strains are nearly identical and their symptoms are similar, so doctors can not readily distinguish between them...
...until 1933 that a virus was identified as the cause of flu and dubbed influenza A. In 1946-47 another form of A emerged, and about this time virologists working with electron microscopes made an important discovery. They found that the outer coat of each virus particle is studded with hundreds of protein spikes. There are two types: hemagglutinin, a biochemical glue that makes red cells clump together and helps the virus get into cells, and an enzyme called neuraminidase that dissolves the glue and helps the virus get out of cells. These spikes are also the antigenic proteins that...
