Naomi: FoxDie is a type of retrovirus that targets and kills only specific people. First, it infects the macrophages in the victim's body. FoxDie contains smart enzymes, created through protein engineering. They're programmed to respond to specific genetic patterns in the cells.
Snake: Those enzymes recognize the target's DNA?
Naomi: Right. They respond by becoming active, and using the macrophages, they begin creating TNF epsilon. It's a type of cytokine, a peptide which causes cells to die. The TNF epsilon is carried along the bloodstream to the heart, where they attach to the TNF receptors in the heart cells.
Snake: And then...they cause a heart attack?
Naomi: The heart cells suffer a shock and undergo an extreme apoptosis. Then... the victim dies.
