American scientists have created HIV-resistant cells that could one day pave the way for controlling the virus without using harsh anti-retroviral drugs.

Scientists at the Keck School of Medicine, at the University of Southern California, used mice to test the cells that target one of the two "gateway" molecules that the Human Immunodeficiency Virus (HIV) uses to enter human cells, Meghan Lewit, spokeswoman for the team of researchers, said.
