Proteomic analysis of Alzheimer's disease Approximately 15 percent of people who live to the age of 65 will develop some form of dementia; by age 85, that proportion increases to at least 35 percent. The most common of all the dementias is Alzheimer's disease. Four million Americans currently suffer from the condition, and experts estimate that 22 million people around the world will be so afflicted by 2025. Aß42 plays a key role in the development of disease and we have recently reviewed a number of highly exciting strategies that appear to selectively reduce the accumulation of this protein ((Click here for free access to our recent dossier "CEB-2001, a therapeutic candidate for Alzheimer's disease identified using AMYScreen an HTS screen for specific inhibitors of Ab42 accumulation"). Even with the development of strategies such as these, targeting additional peptides will likely be necessary for full disease control. In order to identify novel targets, researchers from New Zealand compared the proteomic profile of brain tissue from Alzheimer's disease patients with that from age-matched controls. Six different brain regions were investigated. 76 proteins were differentially expressed in Alzheimer's disease hippocampus compared with age-matched controls, 62 proteins were differentially expressed in temporal cortex, and 39 proteins were differentially expressed in entorhinal cortex. Significant differences were also present in relatively spared regions. Thus, 34 proteins were differentially expressed in Alzheimer's disease cerebellum compared with age-matched controls, 125 proteins were differentially expressed in cingulate gyrus, and 75 proteins were differentially expressed in sensorimotor cortex. The identity of 37 of these proteins was determined, and the possible relevance of changes in key pathogenic pathways analyzed. Collaboration with this group should allow a more complete understanding of disease causing mechanisms and more efficient target identification.
