For the first time, researchers have experimentally induced antibodies that neutralize HIV-1 and simultaneously recognize both HIV-1 envelope protein and lipids. The results were reported by U.S. Military HIV Research Program (MHRP) researchers on Aug. 25 in the online version of AIDS, the official journal of the International AIDS Society.The lead investigators, Dr. Gary Matyas and Dr. Carl Alving, researchers in the Division of Retrovirology, MHRP, Walter Reed Army Institute of Research...

A team of researchers from The Wistar Institute and the University of Pennsylvania reports new evidence refuting a popular hypothesis about the highly publicized failure in 2007 of the Merck STEP HIV vaccine study that cast doubt on the feasibility of HIV-1 vaccines. The findings were published on-line July 20 in Nature Medicine. The phase II STEP vaccine trial was stopped after an interim analysis showed no efficacy in preventing HIV infection in at-risk individuals. It was noted that a...

Most vaccines that protect against viruses generate infection-fighting proteins called antibodies that either block infection or help eliminate the virus before it can cause disease. Attempts to create a vaccine that induces antibodies that prevent HIV infection or disease, however, have so far been unsuccessful. But several recent studies suggest promising new research directions for the development of an antibody-based HIV vaccine, according to John R. Mascola, M.D., deputy director of the...

Human Immunodeficiency Virus (HIV) researchers at The University of Texas Medical School at Houston believe they have uncovered the Achilles heel in the armor of the virus that continues to kill millions. The weak spot is hidden in the HIV envelope protein gp120. This protein is essential for HIV attachment to host cells, which initiate infection and eventually lead to Acquired Immunodeficiency Syndrome or AIDS.  Normally the body's immune defenses can ward off viruses by making proteins...
