Explain the process of blood sample collection from a cancer patient for CAR T-cell therapy?
Explain the process of blood sample collection from a cancer patient for CAR T-cell therapy?
Blood is collected from the cancer patient following standard phlebotomy procedures. The Peripheral Blood Mononuclear Cells (PBMCs) are then isolated from the whole blood using density gradient centrifugation, and T cells are enriched from the PBMCs using magnetic bead separation or fluorescence-activated cell sorting (FACS).
Describe the steps involved in T cell activation and expansion for CAR T-cell therapy?
Describe the steps involved in T cell activation and expansion for CAR T-cell therapy?
The isolated T cells are activated using anti-CD3 and anti-CD28 antibodies or other activation stimuli to promote T cell proliferation and increase their receptiveness to gene transfer. Subsequently, the activated T cells are expanded in culture medium supplemented with cytokines, such as interleukin-2 (IL-2), to increase their numbers.
What is the role of cytokines in the T cell expansion process for CAR T-cell therapy?
What is the role of cytokines in the T cell expansion process for CAR T-cell therapy?
Cytokines, such as interleukin-2 (IL-2), are used to supplement the culture medium during T cell expansion to increase the numbers of activated T cells.
