Scientists discover how T cell assassins reload their weapons to kill and kill again.
Cambridge researchers have discovered how T cells – an important component of our immune system – are able keep on killing as they hunt down and kill cancer cells, repeatedly reloading their toxic weapons.
Cytotoxic T cells are specialist white blood cells that are trained by our immune system to recognize and eliminate threats – including tumor cells and cells infected with invading viruses, such as SARS-CoV-2, which causes COVID-19. They are also at the heart of new immunotherapies that promise to transform cancer treatment.
