Abstract
NLRP3 deficiency led to a significant decrease in tau pathology and hippocampal atrophy in a mouse model of tauopathies.
- Tau pathology in the hippocampus and cortex was significantly lower in NLRP3-deficient mice compared to those with normal NLRP3.
- NLRP3 deficiency was associated with reduced hippocampal atrophy, suggesting a role of NLRP3 in neurodegeneration.
- The absence of NLRP3 significantly decreased the prion-like seeding and propagation of tau pathology.
- Decreased tau pathology was observed in the hippocampus and cortex following tau seeding in NLRP3-deficient mice.
- Hippocampal atrophy at 8 months was significantly less in tau-seeded NLRP3-deficient mice.
