10 Questions
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?
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?
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.
How can T cells be genetically engineered for CAR T-cell therapy?
T cells can be genetically engineered for CAR T-cell therapy by introducing the chimeric antigen receptor (CAR) gene into the T cells, which allows them to recognize and target cancer cells.
What are the two methods used for T cell enrichment from PBMCs for CAR T-cell therapy?
The two methods used for T cell enrichment from PBMCs for CAR T-cell therapy are magnetic bead separation and fluorescence-activated cell sorting (FACS).
What are the standard phlebotomy procedures for collecting a blood sample from a cancer patient for CAR T-cell therapy?
a. Collect a blood sample from the cancer patient following standard phlebotomy procedures.
How can T cells be enriched from PBMCs for CAR T-cell therapy?
c. Enrich the T cell population from the PBMCs using magnetic bead separation or fluorescence-activated cell sorting (FACS).
What activation stimuli can be used to activate the isolated T cells for CAR T-cell therapy?
a. Activate the isolated T cells using anti-CD3 and anti-CD28 antibodies or other activation stimuli.
What cytokines can be used to increase the numbers of activated T cells for CAR T-cell therapy?
c. Expand the activated T cells in culture medium supplemented with cytokines, such as interleukin-2 (IL-2), to increase their numbers.
What is the purpose of T cell expansion in the context of CAR T-cell therapy?
b. Expand the activated T cells in culture medium supplemented with cytokines, such as interleukin-2 (IL-2), to increase their numbers.
