Expression profiling of laser-microdissected tissue from Tg2576 plaque-depositing mouse model of Alzheimer's disease


ABSTRACT: Amyloid-M-CM-^_ (AM-CM-^_) plaques are pathological hallmarks of Alzheimer disease. However, the precise neuropathological changes that occur in brain in response to amyloid deposition are largely unknown. To study the molecular mechanism(s) responsible for AM-CM-^_-mediated neuropathology, we performed a gene expression analysis on laser-microdissected brain tissue of Tg2576 mice compared to their littermate controls. 4 samples; 2 biological replicates of each condition = 2 transgenic versus 2 non-transgenic mice; double amplification of total RNA; only Cy3; no dye-swaps

Amyloid-beta (Abeta) plaques are pathological hallmarks of Alzheimer disease (AD). In addition, innate inflammatory responses, such as those mediated by microglia, are integral to the pathogenesis of AD. Interestingly, only dense-core plaques and not diffuse plaques are associated with neuritic and inflammatory pathology in AD patients as well as in mouse AD models. However, the precise neuropathological changes that occur in the brain in response to amyloid deposition are largely unknown. To st  ...[more]
