NK cells switch from granzyme B to death receptor–mediated cytotoxicity during serial killing
Natural killer cells can kill infected and transformed cells via two different cell death mechanisms. Prager et al. show that NK cells quickly kill their first targets by releasing cytotoxic granulesExpand
