T-cells can recognize and kill tumour cells by using similar mechanisms as for eradicating virally infected cells. T-cells kill their targets through induction of apoptosis, either via death receptors or by secretion of granzymes and perforin[1].

Chimeric antigen receptors (CARs) are human leukocyte antigen (HLA)-independent fusion molecules that couple the binding of a native tumour-associated target, displayed on the surface of tumour cells, to the delivery of a tailored T-cell activating signal. T-cells genetically engineered to express CAR receptors efficiently recognize and kill their target cells. Since an antibody scFv is used to retarget the T-cell, they can be targeted to any available cell surface marker on the tumour cell[1,2].

CAR T-cells can be easily engineered from patient blood and reinfused to the patient after ex vivo expansion. Most of the CARs in current clinical trials join an extracellular single-chain variable fragment (scFv) with the T cell receptor CD3ζ signaling domain as well as an additional domain, CD28 or 4-1BB, to supply a co-stimulatory signal, which appears to be vital for in vivo expansion and persistence[3].
