University of California: Engineering Immune Cells to Recognize and Kill Cancer

Immune cells are the body’s natural way of attacking infections and other invading pathogens. However, since cancer is not foreign (tumors are mutated versions of the body’s own cells), immune cells do not attack most cancer cells. Find out how scientists are using immune proteins to mobilize immune cells to fight cancer with Michael Fischbach, …
