CAR T cell
Chimeric antigen receptor T cells (CAR T cells)—also known as chimeric immunoreceptors, chimeric T cell receptors or artificial T cell receptors—are receptor proteins that have been engineered to give T cells the new ability to target a specific antigen. The receptors are chimeric in that they combine both antigen-binding and T cell activating functions into a single receptor. CAR T cell therapy is a cell therapy that uses T cells engineered with CARs to treat cancer. T cells are modified to recognize cancer cells and destroy them. The standard approach is to harvest T cells from patients, genetically alter them, then infuse the resulting CAR T cells into patients to attack their tumors. CAR T cells can be derived either autologously from T cells in a patient's own blood or allogeneically from those of a donor. Once isolated, these T cells are genetically engineered to express a specific CAR, using a vector derived from an engineered lentivirus such as HIV (see lentiviral vector in gene...
