The process of CAR therapy involves several key steps: 1. Collection: T cells are collected from the patient's blood through a process called apheresis. 2. Modification: The collected T cells are genetically modified in the laboratory to express CARs that are specific to antigens found on the patient's cancer cells. 3. Expansion: The modified T cells are then multiplied to create a sufficient quantity for treatment. 4. Infusion: The engineered T cells are infused back into the patient, where they seek out and destroy cancer cells.
