But for immunotherapy\u2014and for all medicines based on living human cells\u2014there\u2019s a sticky problem: once you train cells to attack a tumor, or kill bacteria, or build cartilage in an arthritic knee, how do you turn them off when the job is done?<\/p>\n<p>\u201cA challenge for doctors will be to control these living entities while they are in the body, allowing them to carry out their curative properties while not letting them get out of hand,\u201d says <a href=\"https:\/\/www.bu.edu\/eng\/profile\/john-t-ngo-ph-d\/\">John Ngo<\/a>, assistant professor of biomedical engineering at Boston University. \u201cThis is a new paradigm, and the rules regarding how to control therapeutic cells still remain to be written.\u201d<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.futurity.org\/engineered-cells-immunotherapy-1801642\/\" class=\"button\">Read complete story on Futurity<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have come up with a tool that offers a means of control over engineered cells, and it comes from a seemingly unlikely source: the hepatitis C genome.
