LONDON (Reuters) - Scientists have found a way to prevent HIV from damaging the immune system and say their discovery may offer a new approach to developing a vaccine against AIDS.

Researchers from the United States and Europe working in laboratories on the human immunodeficiency virus (HIV) found it is unable to damage the immune system if cholesterol is removed from the virus's membrane.

"It's like an army that has lost its weapons but still has flags, so another army can recognize it and attack it," said Adriano Boasso of Imperial College London, who led the study.

Usually when a person becomes infected with HIV, the body's innate immune response puts up an immediate defense. But some researchers believe HIV causes the innate immune system to overreact. This weakens the immune system's next line of defense, known as the adaptive immune response.

For this study -- published on Monday in the journal Blood -- Boasso's team removed cholesterol from the membrane around the virus and found that this stopped HIV from triggering the innate immune response. This in turn led to a stronger adaptive response, orchestrated by a type of immune cells called T cells.

HIV is spread in many ways -- during sex, on needles shared by drug users, in breast milk and in blood -- so there is no single easy way to prevent infection. The virus also mutates quickly and can hide from the immune system, and attacks the very cells sent to battle it.

"HIV is very sneaky," Boasso said in a statement. "It evades the host's defenses by triggering overblown responses that damage the immune system. It's like revving your car in first gear for too long -- eventually the engine blows out.

Alright this could lead to a Cure.....kudos to these guys. I remember years ago they never thought we would be able to come up with a cure. Still these Pharma companies are making people pay if they want to stay alive. Should they wipe out the disease totally? I say yes! Hate unseen bugs.

Hopefully this isn't just another flash in the pan cure we never hear about again. Which happens so much.
