Progression of SIV infection in monkeys raises
A sudden loss of T cells -- white blood cells crucial to the immune system -- is not the trigger for the onset of AIDS, according to a study published in the September 2007 issue of the Journal of Immunology by a team of researchers at Tulane National Primate Research Center.
