Chimeric antigen receptor, or CAR T-cell therapy, is a new form of cell therapy that uses specially altered T cells to more specifically target cancer cells.

The immune system is made up of specific cells and organs that protect the body from infection and cancer. Among these are T cells, which hunt down and destroy abnormal cells, including cancer cells.

After a sample of a patient’s T cells has been collected from the blood, the cells are re-engineered so they sprout special structures called chimeric antigen receptors (CARs) on their surface. When these CAR T cells are reinjected into the patient, the receptors may help the T cells identify and attack cancer cells throughout the body.
