Scientists see encouraging results with new approach for AIDS

Researchers at the University of Pennsylvania, Philadelphia, are using genetic engineering to develop HIV-resistant blood cells, by deleting a gene that allows the virus to infect blood cells.

The idea is based on a man who appears to be cured of AIDS after receiving a blood cell transplant from a donor with natural genetic immunity.

Doctors hope, at the very least, this treatment could repair the immune system enough that patients no longer need to take medication.
