Amyloid plaque load analysis in triple-mutant mouse brains

Brain tissue from APP/PSEN1/GD3S-/- triple-mutant mice was examined for amyloid-beta plaque formation and associated neuropathology. The analysis included assessment of both aggregated and unaggregated Abeta levels using histological and biochemical methods. Brain sections were processed for amyloid plaque visualization and quantification, comparing plaque burden between triple-mutant mice and APP/PSEN1 control mice. The study revealed that elimination of GD3S resulted in almost complete elimination of Abeta aggregation and associated neurodegeneration, providing neuropathological evidence supporting the behavioral improvements observed in these mice.
