An emerging therapy, CAR T-cell therapy, shows promising results in fighting against these dangerous cells (3). The treatment involves five main steps, as shown in Figure . It includes preparation, insertion, activation, expansion, and testing . To begin, the T-cells are extracted from the blood of the cancer patient . Next, the T-cells are inserted with a CAR gene . Once the T-cells have been modified, they are activated through binding to the cancer cell's antigen . To ensure that these T-cells will take effect in the body, the T-cells are duplicated to form more CARs . Lastly, the T-cells are evaluated for safety so the patient can undergo chemotherapy, allowing the CAR T-cells to grow and be inserted into the patient again (3).
