So I work in the Development and Alumni Relations Department for the Perelman School of Medicine at the University of Pennsylvania. We've recently had a doctor, working with other physicians from Childrens Hospital of Philadelphia and other blood cancer docs at Penn, named Carl June who has been working on immunotherapy research to treat cancer for the past 20 years. What they do is take disabled HIV cells and reprogram the immune system to have those cells attack the cancer cells. They've recently had their 7th person treated this way and is now cancer free, but there is still a little to see if it comes back. Check out the article below about the sixth person, little girl Emily Whitehead, I don't know if I'll post it right....
