The olfactory molecular snapshot in aged Tg2576 Alzheimer´s disease mouse model

Olfaction is often deregulated in Alzheimer´s disease (AD) patients, being also impaired in transgenic Tg2576 AD mouse model, which overexpress the Swedish mutated form of human amyloid precursor protein (APP). However, little is known about the molecular mechanisms that accompany the neurodegeneration of olfactory structures in Tg2576 mice. For that, we have applied proteome- and transcriptome-wide approaches to probe molecular disturbances in the olfactory bulb (OB) dissected from aged Tg2576 mice (18 months of age) respect to age matched wild-type (WT) littermates.
