摘要
Age-related cognitive decline and neurodegenerative diseases are a growing challenge for society. Accumulation of tau pathology has been proposed to partially contribute to these impairments. This study provides a behavioral characterization during aging of transgenic mice bearing tau mutations. THY-Tau22 mice were evaluated at ages wherein tau neuropathology in this transgenic mouse model is low (3-4 months), moderate (6-7 months), or extensive (>9 months). Spatial memory was found to be impaired only after 9 months of age in THY-Tau22 mice, whereas non-spatial memory was affected as early as 6 months, appearing to offer an opportunity for assessing potential therapeutic agents in attenuating or preventing tauopathies through modulation of tau kinetics.
