03Scientific explanation
CAR: chimeric antigen receptor, an antibody part plus a T-cell signalling part.
B-cell aplasia: CAR-T also destroys healthy B cells, so immunoglobulin may be needed.
04What happens in the body?
What CAR-T is
T cells are collected from your blood, and in the lab they are given a new receptor, a CAR, that recognises a leukaemia marker (for example CD19). They are multiplied and returned to you. Today it is used mainly in relapsed or refractory B-cell ALL and some lymphomas. It is given once, but the cells can live in the body for a long time.
