Natural killer (NK) cells of the immune system identify cancer and virally-infected cells and kill them. These potent killers travel throughout the body, recognizing proteins and other molecules on the surface of cells. In order to differentiate between healthy and diseased cells, NK cells use a variety of receptors, which bind to specific ligands at the target cells’ surface. The balance between activating and inhibitory signals will tell the NK cell if the target cell is diseased or healthy, respectively. If the target cell is deemed potentially dangerous, the NK cell grips the target cell tightly and creates an immunological synapse at the site of adhesion. Within this immunological synapse, the NK cell releases cytotoxic granules to kill the target cell without harming any nearby cells allowing for a direct, apoptotic death.

Our team will focus on improving killer cells’ specificity and killing efficiency towards cancer target cells. By using tools of synthetic biology, we hope to create powerful killing bio-machines for the fight against cancer. Our newly engineered synthetic devices would have the potential to enhance current adaptive cell-based immunotherapy for cancer patients.
