Immunotherapy is an emerging trend in current cancer treatment. It enhances our immune system’s ability to recognize cancer cells and strengthen immune response to kill tumor.
T cell immunotherapy is an approach which enhances and activate T cells inside our body. Memory T cells are highly specific to tumors and have long life-span thus they can provide our body with long term tumor surveillance and eliminate cancer cells efficiently. In comparison, effector T cell acts on local tumor sites only and therefore has short lifespan.
In actually clinical settings, blood is collected from the patient during the initial step. Isolation, activation and expansion of T cells is conducted in the laboratory. And finally, the T cells which are now being expanded are then infused back into the patient to fight against cancer cells.
