A study conducted at John Hopkins University in Baltimore and Imperial College London may have found a way of preventing HIV from damaging the immune system.

The research suggests that HIV cannot damage the immune system if the cholesterol is eliminated from the virus's membrane.

Some researchers believe HIV overwhelms the immune system by causing it to overreact. This is called adaptive immune response.

Scientists discovered that HIV was blocked from spreading once the cholesterol was removed from its membrane.

Author Adriano Boasso of Imperial College London, said, "It's like an army that has lost its weapons but still has flags, so another army can recognize it and attack it", reported Indian Express.
