Proteomics on post-mortem human brain tissue of patients with Alzheimer`s, Parkinson`s and Lewy body dementias.

ABSTRACT: We have used HiRIEF (High Resolution Isoelectric Focusing) LC-MS proteomics with isobaric tags (TMT10plex) to compare 32 post-mortem human brains in the prefrontal cortex (Brodmann area 9) of prospectively followed patients with Alzheimer`s disease (AD), Parkinson`s disease with dementia (PDD), dementia with Lewy bodies (DLB) and older adults without dementia.

See Attems and Jellinger (doi:10.1093/brain/awx360) for a scientific commentary on this article.Cognitive changes occurring throughout the pathogenesis of neurodegenerative diseases are directly linked to synaptic loss. We used in-depth proteomics to compare 32 post-mortem human brains in the prefrontal cortex of prospectively followed patients with Alzheimer's disease, Parkinson's disease with dementia, dementia with Lewy bodies and older adults without dementia. In total, we identified 10 325  ...[more]
