Researchers at Duke University have found a potent and rare antibody they believe may be a key to developing a vaccine for HIV, the virus that causes AIDS. The anti-body, called 2F5-like antibody, has been shown to be effective in removing up to 80 percent of virus in an infection.
The antibody had never been found circulating in the body until now which is what has researchers excited.
“The 2F5-like antibody is one of the gold standards for what an HIV vaccine needs to induce, but no one had ever found it before circulating in the blood of infected patients,” says Georgia Tomaras, PhD, associate professor of surgery, immunology and molecular genetics and microbiology in the Duke Human Vaccine Institute and the senior author of the study.
Researchers said they checked the blood of 300 HIV infected individuals and found the 2F5-like antibody in only one person. Researchers also discovered that the antibody is made by the body long after the initial infection with the virus, rendering the effect neutral.
They hope to use the antibody to create a vaccine.
