Progress, no big breakthrough, in hunt for HIV cure


Scientists, stymied for decades by the complexity of the human immunodeficiency virus, are making progress on several fronts in the search for a cure for HIV infections, a leading medical research conference was told this week in Seattle.

Promising tactics range from flushing hidden HIV from cells to changing out a person's own immune system cells, making them resistant to HIV and then putting them back into the patient's body.

A major stumbling block is the fact that HIV lies low in pools or reservoirs of latent infection that even powerful drugs cannot reach, scientists told the Conference on Retroviruses and Opportunistic Infections, one of the world's largest scientific meetings on HIV/AIDS.

“We need to get the virus to come out of the latent state, then rely on the immune system or some other treatment to kill the virus," said Dr. Kevin De Cock, director of the Center for Global Health at the U.S. Centers for Disease Control and Prevention.
