Title	Localised protein expression changes in different regions of human Alzheimer’s brain correlate with disease severity - Motor cortex
Description	Human brain tissue was obtained from the New Zealand Brain Bank from donors with Alzheimer's disease (AD) or age-matched controls (n=9/group). Mean post mortem delays were ~12h. Six distinct brain regions were dissected, Hippocampus, Cingulate Gyrus, Entorhinal Cortex (severely affected), Motor and Sensory Cortex (less affected) and Cerebellum (spared). Protein was extracted from each sample and, each region was analysed independently. For each region, samples were divided into 3 sets of 3 cases and 3 controls and assigned to an iTRAQ 8 plex, alongside two aliquots of a pooled QC sample. Samples were digested, iTRAQ labelled and analysed. For each region, between 3000 and 4200 proteins were compared between AD and control, identifying a series of known and novel protein expression changes associated with the progression of AD.
