"Researchers report that they've gained more insight into how the body fights off HIV, a finding that offers a possible new avenue toward a vaccine against the virus, which causes AIDS," HealthDay/MSN reports. "The researchers found four kinds of antibodies that appear to create a barrier that prevents HIV" from entering cells, according to the news service. They describe their findings in the Journal of Experimental Medicine (Dotinga, 4/5). In related news, VOA News examines how researchers hope studies of antibodies to HIV will help guide new avenues for HIV vaccine development (DeCapua, 4/5).
