The secret of HIV control
The immune tricks that keep HIV in check in long term non-progressors (LTNPs) -- people who carry the virus but don't get AIDS -- have been a mystery for decades. It turns out that T cells in LTNPs destroy the virus by punching holes in infected cells and injecting a strong dose of apoptotic proteins, according to a study to be published in the December 19th issue of Immunity. "This study brings us closer to a potential vaccine or cure for AIDS," linkurl:Guido Silvestri;http://www.med.upenn.edu
