Doctors use HIV to cure Utah mans leukemia — A man who was diagnosed with an extremely aggressive form of cancer two years ago is now amazingly in remission thanks to a revolutionary treatment that involved receiving an infusion of the virus that causes AIDS. Marshall Jensen of Utah, was one of 30 leukemia patients to undergo a trial treatment at Penn Medicine recently, in which white blood cells are implanted with a harmless form of HIV programmed to target and kill cancer. How It Works? The new immunotherapy treatment begins with a doctor removing a patient’s T cells from the blood. Next, they reprogram the T cells, a type of white blood cell essential for our immunity, using HIV. Although the virus has been “disabled” in the lab, it retains one key property of HIV: it has the ability to insert new genes into cells. Next, genetically modified T cells are grown in the lab and then re-infused into the patient. Finally, the patient’s modified T cells begin to circulate once again within the blood stream, but this time they recognize and bind to cancerous tumor cells. youtube/watch?v=JmSym47pwSg#t=11
