Reach for the disarmament of the AIDS virus?

Scientists find way to disarm the AIDS virus

LONDON (Reuters)

Scientists have found a way to prevent AIDS virus from destroying the immune system and say the discovery may provide a new approach to develop a vaccine for the prevention of the deadly disease.

The scientists concluded from the United States and Europe working in the laboratory of HIV that the virus becomes capable of destroying the immune system in the case of the removal of cholesterol from Gchaúh.

Adriano said Boisson from Imperial College London, who led the study, "It's like the army has weapons but still has the flags of the army can identify him and another attack."

The team plans now to discuss how to use this method to eliminate the virus and may develop a vaccine.

Usually when a person becomes infected (virus. No. In) that causes AIDS, the immune response, innate defense of the body immediately. But some researchers believe that the AIDS virus makes the innate immune system over-reaction. This weakens the next line of defense for the immune system known as adaptive immune response.

During the study, published in the journal (blood) "Blood" on Monday, a team Boisson to remove cholesterol from the membrane surrounding the virus only to find that this is to prevent the virus from the operation of the innate immune system. This in turn led to stronger adaptive response regulated by the type of immune cells known as T cells.

AIDS kills about 1.8 million people annually around the world. And injured as many as 2.6 million people with HIV in 2009 and 33.3 million live with HIV infected person.

Try and scientists from companies and nonprofit organizations and governments around the world for many years to produce a vaccine against HIV, but so far not been achieved only limited success.

A study in Thailand in 2009 included 16 000 volunteers for the first time that a vaccine can prevent HIV infection in a small number of people, but because the efficiency was about 30 percent, the researchers had to return to the beginning of the road.
