Scientists Uncover HIV Escape Route from Drugs and Vaccines

Virologists at Jefferson Medical College may have discovered a new way by which HIV, the AIDS virus, can evade both anti-viral drugs and vaccines. Researchers had reported last summer that a protein called CEM15 is a natural inhibitor of HIV, acting as a brake on HIV’s replication. They also showed that an HIV-encoded protein, Vif, or Virion infectivity factor, counteracts CEM15. Vif, in effect, is a shield to protect HIV from a host cell’s defenses.

Researcher ID new target for anti-HIV drugs

Researchers say they have discovered a new target on the HIV molecule that could potentially lead to a new class of anti-viral drugs to fight the virus that causes AIDS. “The greatest challenge in treating HIV today is drug resistance brought on when the virus mutates and renders existing drugs ineffective at stopping viral replication,” said a lead researcher. “Our research has led to the identification of a new class of compounds that inhibit a novel target in HIV. These compounds disrupt the assembly of the HIV-1 capsid protein, which is a vital step in changing immature, non-infectious HIV into its mature, infectious form.”
