Cholinergic denervation exacerbates amyloid pathology and induces hippocampal atrophy in Tg2576 mice.

Gil-Bea FJ, Gerenu G, Aisa B, Kirazov LP, Schliebs R, Ramirez MJ (2012) Cholinergic denervation exacerbates amyloid pathology and induces hippocampal atrophy in Tg2576 mice. Neurobiol Dis 48(3):439-446. doi: 10.1016/j.nbd.2012.06.020

Summary: The hallmarks of Alzheimer’s disease (AD) include hippocampal cell loss, cholinergic dysfunction, amyloid plaques, and neurofibrillary tangles, among other things. This work sought to examine the interaction between cholinergic denervation, amyloid precursor protein (APP) processing, and hippocampal integrity. Tg2576 transgenic mice received 2 μg of mu p75-SAP (Cat. #IT-16) injected into the third ventricle. These mice overexpress a version of human APP. Lesioned animals displayed various aspects of AD such as hippocampal synaptic pathology and neurodegeneration, indicating that immunolesions in this mouse line produce a viable model for AD.
