MINNEAPOLIS / ST. PAUL -- Researchers at the University of Minnesota have discovered a new process by which HIV damages the immune system. They demonstrated that the portion of lymph nodes called the T cell zone is significantly damaged by chronic inflammation, which causes fibrosis. This is important because the T cell zone is where a significant portion of the human immune response occurs. The finding of accumulation of scar tissue in this portion of the lymph node may explain why aggressive anti-retroviral therapy (ART) does not improve the immune system in some people with HIV-1 infection. The study findings will be published in the Oct. 16, 2002, issue of the Journal of Clinical Investigation. The paper can be found at http://www.jci.org.
