title: How do macrophages distinguish the living from the dead?
abstract: Injection of live but not dead bacteria induces a wave of IL-12 and subsequently, IFN-gamma production. Surprisingly, in vitro, both live and dead bacteria elicit IL-12 from macrophages. Better understanding of how macrophages distinguish live from dead bacteria would help explain this difference and possibly bypass the need for live vaccines against intracellular bacteria.
