We call it caspase eight, but it's still protease. And what that means is once we activate the cat space nine inside the cell, that cat space I'm sorry, cat space eight. Once we activate the cat space eight, it will go on to basically destroy the organelles and the structures inside the cell as well as the DNA inside the nucleus of that cell. And that will eventually lead to the death of that cell. And once the cell dies, once again, a macrophage or another phagocytic cell can swim by engulf that dead cell. And that will prevent that infected cell from actually destroying other healthy cells of our body.
