Giving HIV a Poor Reception: New AIDS Treatment Tinkers with Immune Cell Genes

BOSTON--A novel treatment for HIV could involve changing the genes in a person's immune cells and, ultimately, in his or her stem cells, as well. It might even lead to a cure for that deadly disease. Promising advances in that direction were presented here Monday at the 18th Conference on Retroviruses and Opportunistic Infections.

The pieces have been coming together for some time. First came the understanding that HIV enters a cell by grabbing on to a CD4 receptor molecule on the surface, and then on to a co-receptor molecule--the one most commonly used is called CCR5.
