Terapia de células T con CAR; en el dibujo se muestra que se extrae sangre de una vena del brazo de un paciente para obtener células T. También se muestra que se prepara en el laboratorio un receptor especial, que se llama receptor de antígeno quimérico (CAR); se inserta el gen que produce el CAR en las células T y luego se reproducen millones de células T con CAR. Además, se muestra que el paciente recibe las células T con CAR por infusión, y que luego estas células se unen a los antígenos de las células cancerosas y las destruyen.
