Plaque-associated α-synuclein (NACP) pathology in aged transgenic mice expressing amyloid precursor protein

Patients with the Lewy body variant (LBV) of Alzheimer's disease (AD) have ubiquitinated intraneuronal and neuritic accumulations of α-synuclein and show less neuron loss and tau pathology than other AD patients. Aged Tg2576 transgenic mice overexpressing human βAPP695. KM670/671NL have limited neuron loss and tau pathology, but frequent ubiquitin- and α-synuclein-positive, tau-negative neurites resembling those seen in the LBV of AD.
