Sangamo's Bet Against AIDS: Gene Therapy

BusinessWeek: "Timothy Brown may be the only person cured of AIDS. Brown, who lives in San Francisco, in 2007 received a stem-cell transplant in Berlin that transferred genetic material to him from one of the up to 2 percent of humans with a natural immunity to the disease. He has been off treatment since then, and no traces of the AIDS virus have been found in his body, says his hematologist, Gero Hütter, now with the German Red Cross in Mannheim. His case has encouraged tiny Sangamo BioSciences (SGMO) to develop a new form of gene therapy that could offer others the same result."
