Peripheral dendritic cell priming of CD8 + T cells drives tau-related neurodegeneration
Key Takeaways
  • Peripheral cDC1 cells are required to prime CD8+ T cells that infiltrate the brain in the tauopathy model.
  • Eliminating peripheral CD8+ and CD4+ T cells provided neuroprotection in the studied tau model.
  • The study links peripheral cross-presentation by cDC1s to worsening tau-mediated neurodegeneration in mice.
