Researchers from Queen Mary University of London, have identified a protein that may represent a novel therapeutic target for the treatment of pancreatic cancer. Using this protein as a target, the team successfully created a CAR T cell therapy - a type of immunotherapy - that killed pancreatic cancer cells in a pre-clinical model.
CAR T cell therapy is an immunotherapy that has shown great promise for the treatment of some blood cancers; however, the treatment of solid tumours using this therapy has proved very difficult. One barrier to success is toxicity in tissues other than the cancer because most of the proteins currently used to target CAR T cells to pancreatic cancer cells and other solid tumours are present in low levels on other normal tissues, leading to toxic side effects.
