| abstractText | INTRODUCTION: People with DS are highly predisposed to Alzheimer's disease (AD) and demonstrate very similar clinical and pathological features. Ts65Dn mice are widely used and serve as the best-characterized animal model of DS. METHODS: We undertook studies to characterize age-related changes for AD-relevant markers linked to Abeta, Tau, and phospho-Tau, axonal structure, inflammation, and behavior. RESULTS: We found age related changes in both Ts65Dn and 2N mice. Relative to 2N mice, Ts65Dn mice showed consistent increases in Abeta40, insoluble phospho-Tau, and neurofilament light protein. These changes were correlated with deficits in learning and memory. DISCUSSION: These data have implications for planning future experiments aimed at preventing disease-related phenotypes and biomarkers. Interventions should be planned to address specific manifestations using treatments and treatment durations adequate to engage targets to prevent the emergence of phenotypes. |
