Tau aggregates in PS19 mice are linked to neuronal death via ZBP1 activation, driven by endogenous Z-RNAs from reactivated transposable elements.
- Why it matters: Tau neurotoxicity is a key driver of neurodegeneration, but therapies that directly target how tau aggregates kill neurons remain limited.
- What they did: In PS19 tau-expressing neurons, ZBP1 is activated by Z-RNAs produced when transposable elements escape heterochromatin silencing; tau aggregates bind H3K9me3 chromatin and sequester HP1.
- The result: ZBP1 expression in excitatory neurons is inversely correlated with cognitive performance in Alzheimer’s disease, and Zbp1 haploinsufficiency significantly improves cognition in aged 24-month-old tau-transgenic mice.
