Car T Cell Development

These altered t cells can now recognize and attack cancer cells specifically.

Car t cell development.

Once the collected t cells have been engineered to express the antigen specific car they are expanded in the laboratory into the hundreds of millions. The development of car t cells is a complex process that requires multiple components in the workflow including i screening and sequencing of mabs that are specific to the cancer antigens. Car t cells may be manufactured either from the patient s own blood known as an autologous treatment or from the blood of a healthy donor known as an allogeneic treatment. The first step in the production of car t cells is the isolation of t cells from human blood.

The manufacturing process is the same in both cases. Adoptive cell therapy using cd19 targeted car t cells has resulted in remarkable responses in patients with acute lymphoblastic leukemia 3. Adoptive cell therapy using naturally occurring endogenous tumor infiltrating lymphocytes or t cells genetically engineered to express either t cell receptors 1 or chimeric antigen receptors car 2 have emerged as promising cancer immunotherapy strategies. The car t cell therapies furthest along in development target an antigen found on b cells called cd19 see the box below titled the making of a car t cell.
