NEW YORK (AP) — Two new studies suggest that doctors may one day be able to control a patient's HIV infection in a new way, by injecting swarms of germ-fighting antibodies.
The studies, done in monkeys, found that this approach sharply reduced blood levels of a cousin of HIV. The results also gave tantalizing hints that someday the strategy might help destroy the AIDS virus in its hiding places in the body, something current drugs cannot do.
Antibodies are proteins in the blood that grab onto specific germs and mark them for elimination. In one study of infected monkeys, a single injection of antibodies made the virus undetectable in the bloodstream within a week. Once the antibodies petered out, the virus usually returned. But experts said the strategy could help produce a cure.
