NK cells serve as a potential immunotherapeutic tool due to their innate ability to kill cancer cells. They play a crucial role in cancer prevention by providing immune surveillance, making them attractive candidates for immunotherapeutic tool. However, quite often NK cell can fail to recognize and eradicate residual cancer cells, resulting in cancer relapse and lower chance of survival. In this webinar, Prof. Mark Lowdell, Chief Scientific Officer of INmune Bio, Inc. discussed how primed NK cells become effective against resistant tumor cells, and how cell avidity measurements were used to depict a stronger binding of primed NK cells, resulting in improved tumor cell killing.
