(Submitter supplied) Alzheimer's Disease (AD) is a devastating neurodegenerative disorder affecting approximately 4 million people in the U.S. alone. AD is characterized by the presence of senile plaques and neurofibrillary tangles in cortical regions of the brain. These pathological markers are thought to be responsible for the massive cortical neurodegeneration and concomitant loss of memory, reasoning, and often aberrant behaviors that are seen in patients with AD. more...

Analysis of entorhinal cortex neurons containing neurofibrillary tangles (NFT) from 10 mid-stage Alzheimer's disease (AD) patients. Comparison with histopathologically normal neurons from the same patients and brain region. Results provide insight into the formation of NFTs in AD.

(Submitter supplied) Information about the genes that are preferentially expressed during the course of Alzheimer’s disease (AD) could improve our understanding of the molecular mechanisms involved in the pathogenesis of this common cause of cognitive impairment in older persons, provide new opportunities in the diagnosis, early detection, and tracking of this disorder, and provide novel targets for the discovery of interventions to treat and prevent this disorder. more...

(Submitter supplied) We used Illumina Human HT-12 v4 arrays to compare RNA expression of middle temporal gyrus (MTG; BA21) in Alzheimer’s Disease (AD = 97) and non-demented controls (ND = 98). A total of 938 transcripts were highly differentially expressed (adj p < 0.01; log2 Fold Change (FC) ≥ |0.500|, with 411 overexpressed and 527 underexpressed in AD. Our results correlated with expression profiling in neurons from AD and ND obtained by Laser Capture Microscopy in MTG from an independent dataset (log2 FC correlation: r = 0.504; p = 2.2e-16). more...
