How modified T-cell cancer therapy works

Blood drawn

1. Blood is drawn from the patient and T-cells are separated out

T-cells normally

kill pathogen-

infected cells

2. The T-cells are engineered to produce surface receptors called CARs

Engineered

T-cell with

receptors

3. These receptors allow T-cells to attach to a specific protein on tumour cells

Cancerous

cell

4. The CAR

T-cells are multiplied in the lab

Hundreds

of millions

produced

5. Transfused into the patient, CAR

T-cells recognise and kill cancer cells

Modified

T-cell infusion
