Abstract:
Neuroinflammation contributes to Alzheimer's disease (AD), but the molecules and pathways that initiate inflammation are unclear. In this issue of Immunity, Song et al. demonstrate that ZBP1-RIPK1 signaling in microglia can drive AD, wherein ZBP1 is activated by left-handed Z-DNA leaking from mitochondria, presenting new molecular targets for AD therapeutics.
