This study also highlights the fundamental difference between tau physiological cell-to-cell transfer and tau pathological propagation. with cold 0.9% NaCl followed by cold 4% PFA for 20?min. The brains were immediately removed, fixed overnight in 4% PFA, placed in 20% sucrose for 24?h and frozen until further use. Free-floating coronal cryostat sections (40?m thickness) were used for immunohistochemical analysis. For RNA extraction, 2?weeks post-injection, were deeply anesthetised (pentobarbital 50?mg/kg). Brains were dissected, and 1-mm-thick coronal sections were generated using an acrylic rat brain matrix (Electron Microscopy Sciences). The sections were immediately frozen on dry ice and stored at ??80?C until…
