HIV Resistance Mapped by Gene Researchers

Some people have natural defenses that weaken power of virus, study authors say

THURSDAY, Oct. 31 (HealthDay News) — Researchers who created the first map of human resistance to HIV say their achievement could lead to improved treatments for the virus, which causes AIDS.

When a person is infected with HIV, the immune system tries to destroy the virus. In order to thwart those attacks, HIV undergoes millions of genetic mutations a day. In most cases, this tactic enables HIV to defeat the immune system.

However, some people’s immune systems manage to hold HIV at bay without any treatment.

“The virus survives but replicates more slowly, and thus its capacity for destruction is in some sense neutralized,” study co-author Jacques Fellay, of the Swiss Federal Institute of Technology in Lausanne, said in an institute news release. Read more
