Amyloid-β (Aβ) deposits are important pathological hallmarks of Alzheimer's disease (AD). Aβ aggregates into fibrils; however, the intermediate oligomers are believed to be the most neurotoxic species and, therefore, are of great interest as potential biomarkers. Here, we have developed an enzyme-linked immunosorbent assay (ELISA) specific for Aβ oligomers(More)
Amyloid-β protein (Aβ) accumulation is one of the major hallmarks of Alzheimer's disease and plays a crucial role in its pathogenesis. Aβ aggregates into fibrils, but rather than these end-products of the aggregation process, intermediate species, referred to as oligomers, have been identified as the most neurotoxic Aβ aggregates. To characterize the(More)
The fibrillization of α-synuclein (α-syn) is a key event in the pathogenesis of α-synucleinopathies. Mutant α-syn (A53T, A30P, or E46K), each linked to familial Parkinson's disease, has altered aggregation properties, fibril morphologies, and fibrillization kinetics. Besides α-syn, Lewy bodies also contain several associated proteins including small heat(More)
Amyloid-β (Aβ) is the most prominent protein in Alzheimer's disease (AD) senile plaques. In addition, Aβ interacts with a variety of Aβ-associated proteins (AAPs), some of which can form complexes with Aβ and influence its clearance, aggregation or toxicity. Identification of novel AAPs may shed new light on the pathophysiology of AD and the metabolic fate(More)
Amyloid-β (Aβ) is known as the most prominent core protein in Alzheimer's Disease (AD) senile plaques. Although research has focused mainly on Aβ40 and Aβ42 as potential cerebrospinal fluid (CSF) biomarkers, a range of Aβ peptides with variable lengths has been demonstrated in the brains and CSF of AD patients. Recently, it has been found that the Aβ43(More)
BACKGROUND Amyloid-β (Aβ)-oligomers are neurotoxic isoforms of Aβ and are a potential diagnostic biomarker for Alzheimer's disease (AD). OBJECTIVES 1) Analyze the potential of Aβ-oligomer concentrations in cerebrospinal fluid (CSF) to diagnose and predict progression to AD in a large clinical study sample. 2) Monitor Aβ-oligomer concentrations over-time,(More)
Objectives 1) Analyze the potential of amyloid beta (A)-oligomer concentrations in cerebrospinal fluid (CSF) to diagnose and predict progression to Alzheimer's disease (AD) in a large clinical study sample. 2) Monitor A-oligomer concentrations overtime , both in early and advanced stages of AD. 3) Examine the relation between A-oligomer levels in CSF and(More)
