Inhibitor Discovered that Could Lead to H.I.V. Vaccine
Scientists announced that a new compound used to combat H.I.V. infection in primates may be able to function as a vaccine against AIDS. The compound stimulates muscle cells to produce proteins that mimic normal antibodies with Y-shaped heads. The proteins then use both a head and tail to simultaneously block two sites on each "spike" that the virus uses to attach itself to a cell. The twofer may make people's immune systems resistant to the virus. The fight to find a vaccine for the H.I.V. virus has been an ongoing effort for the past 30 years. The current technique has now protected four lab monkeys from the infection for a year.
