CAR
A special receptor created in the laboratory that is designed to bind to certain proteins on cancer cells. The CAR is then added to immune cells called T cells. This helps the T cells find and kill cancer cells that have the specific protein that the receptor is designed to bind. These changed T cells called CAR T cells are then grown in large numbers in the laboratory and given to cancer patients. CAR T cells are being studied in the treatment of some types of cancer. Also called chimeric antigen receptor.
