Soluble amyloid-beta buffering by plaques in Alzheimer disease dementia versus high-pathology controls |pdf=|usr=}}{{29979775 }} gab.com Text Soluble amyloid-beta buffering by plaques in Alzheimer disease dementia versus high-pathology controls JO: PLoS One http://www.kidney.de/pget.php?&tw=1&pmid=29979775 #FOAvip An unanswered question regarding Alzheimer disease dementia (ADD) is whether amyloid-beta (A?) plaques sequester toxic soluble A? species early during pathological progression. We previously reported that the concentration of soluble A? aggregates from patients with mild dementia was higher than soluble A? aggregates from patients with modest A? plaque burden but no dementia. The ratio of soluble A? aggregate concentration to A? plaque area fully distinguished these groups of patients. We hypothesized that initially plaques may serve as a reservoir or sink for toxic soluble A? aggregates, sequestering them from other targets in the extracellular space and thereby preventing their toxicity. To initially test a generalized version of this hypothesis, we have performed binding assessments using biotinylated synthetic A?1-42 peptide. A?1-42-biotin peptide was incubated on unfixed frozen sections from non-demented high plaque pathology controls and patients with ADD. The bound peptide was measured using ELISA and confocal microscopy. We observed no quantitative difference in A? binding between the groups using either method. Further testing of the buffering hypothesis using various forms of synthetic and human derived soluble A? aggregates will be required to definitively address the role of plaque buffering as it relates to ADD.
