Frequently Asked Questions About Immunotherapy for Leukemia

What is immunotherapy for leukemia?

Immunotherapy for leukemia is a treatment approach that leverages the body's own immune system to identify, target, and destroy leukemia cells. It works by enhancing or modifying the immune response to specifically combat cancer, often resulting in a more precise and less toxic treatment compared to traditional methods.

How does CAR T-cell therapy work?

CAR T-cell therapy is a revolutionary immunotherapy that involves several steps: first, T-cells are collected from the patient (leukapheresis). These T-cells are then genetically modified in a lab to express chimeric antigen receptors (CARs), which enable them to recognize specific markers on leukemia cells. Finally, these modified T-cells are expanded and infused back into the patient, where they actively seek out and destroy cancer cells.

What are monoclonal antibodies, and how are they used in leukemia treatment?

Monoclonal antibodies are laboratory-produced molecules that are engineered to mimic the antibodies naturally produced by the immune system. In leukemia treatment, these antibodies are designed to specifically bind to certain proteins on the surface of leukemia cells, marking them for destruction by the immune system or directly inhibiting their growth. Examples include Rituximab and Tisagenlecleucel.
