Adult Stem Cells Help AIDS / Leukemia Patient

Via Bloomberg:

A German AIDS patient was able to stop drugs he had been taking for 10 years after getting a transplant of stem cells from a donor with a rare gene variant known to resist the deadly disease. The transplant also cured his leukemia, researchers reported.

The stem cell donor was among the 1 percent of Caucasians who have the variant gene that lacks a section known as CCR5 that helps the AIDS virus enter a cell, according to a report today in the New England Journal of Medicine. Doctors in Berlin hoped that putting the donor’s stem cells in the patient would rebuild his immune system and blood cells so they would lack the CCR5 piece.

The results of the experiment may point researchers to a new way of controlling the AIDS virus HIV that doesn’t force patients to take drugs for the rest of their lives.
