Scientists find two proteins that can neutralize 90% of HIV strains.

From AOL News:
American scientists are touting a major stride toward a vaccine that can ward off HIV, after finding two key proteins that neutralize 91 percent of the virus' 190 strains.

The team of researchers with the National Institutes of Health's Vaccine Research Center hopes the antibody discovery can spur successful work toward a method of preventing HIV, which already afflicts an estimated 33 million people worldwide.

The discovery, published in this week's Science, is courtesy of Donor 45, an unidentified African-American man whose body produced the antibodies, called VRC01 and VRC02.

Scientists have already identified the 12 cells in his body that produced the proteins. If they can harness the mechanisms by which the antibodies were made, they might be able to create a vaccine that would spur anybody's body to make the HIV destroyers.
