The finding could point the way to create an AIDS vaccine. Researchers at Scripps Research Institute in La Jolla, California, have managed to isolate the two antibodies responsible for disease resistance in an African man. These antibodies prevent many strains of HIV from multiplying in the body and end up producing the disease AIDS.
Furthermore, the discovery appears to be important, since these antibodies attack a portion of the HIV virus that had not previously taken into account for the manufacture of a vaccine, which means that in any case, the discovery opens new avenues research.
To carry out this study, scientists took blood samples from 1,800 people in Thailand, Australia and Africa, to be carried at least three years infected yet not shown any infection from the disease.
The antibodies isolated from African patients are PG9 and PG16, and together with able to block three-quarters of the 162 strains of HIV that have been tested.
Still, still years away from achieving the desired vaccine, since the interesting thing would be to create molecules that would create incentives that create these antibodies the body naturally. Either way these antibodies could be used in infected patients who are in more severe stages of the disease.
