BOSTON - A study published on Thursday in " Nature" presents a new potential treatment for HIV . In the experiment , potent antibodies were able to exterminate , in a matter of days , a virus hybrid of man and monkey ( SHIV ) , according to the BBC .
American researchers claim that testing positive patients are underway . The immune system produces antibodies to attack HIV , but the virus is able to rapidly mutate and escape from immune attack . However , some antibodies can attack parts " conserved " HIV .
Two teams , the Harvard Medical School and the National Institute of Allergy and Infectious Diseases , conducted the first tests with the antibodies . They used the rhesus macaque infected with SHIV . The results showed that injection of antibodies led to decrease in the levels of the virus in the bloodstream until it became undetectable after three to seven days.
The effect lasted between one and three months , and in three monkeys the virus did not come into the bloodstream after 250 days of study .
- The effect of these potent antibodies are profound and unprecedented . It is probably the greatest therapeutic effect already seen - told BBC researcher Dan Barouch . - But there is still the limitation that the study was done on animals , not humans.
The antibodies were also capable of attacking the virus in some tissues . Medicines can achieve the virus in the blood during the normal treatment of HIV virus but can conceal other parts of the body.
