Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the presence of extracellular amyloid deposits, consisting largely of Abeta peptide and the presence of intraneuronal aggregates of neurofibillary tangles formed by tau. Development of cerebrospinal fluid (CSF) biomarkers has become a rapidly growing research field, considering the(More)
The microtubule-associated protein Tau, a major component of brain microtubules, shares common repeated C-terminal sequences with the high molecular-weight protein MAP-2. It has been shown that tau peptides V187-G204 and V218-G235 representing two main repeats, induced brain tubulin assembly in a concentration-dependent fashion. The specific roles of these(More)
After the finding of the involvement of the C-terminal moieties of tubulin subunits in the interaction of MAPs, different studies have focused on the substructure of the binding domains for the different MAPs. Current biochemical evidence point to the role of a low-homology sequence between α and β-subunits within the conserved region of the C-terminal(More)
1. Neurofibrillary tangles present in Alzheimer's disease and, in a lower proportion, in aged brains are formed mainly by paired helical filaments. The microtuble-associated protein tau is a major structural component of these filaments. In order to increase our understanding of the aberrant behaviour of tau protein leading to its assembly into paired(More)
BACKGROUND The presence of brain hyperphosphorylated tau constitutes a hallmark of neurodegenerative disorders of the Alzheimer's type. This report describes the relationships between tau markers in the cerebrospinal fluid (CSF), the degree of cognitive impairment and the predictive value of genetic markers such the alleles of apolipoprotein E, namely, the(More)
The intracellular polymerization of cytoskeletal proteins into their supramolecular assemblies raises many questions regarding the regulatory patterns that control this process. Binding experiments using the ELISA solid phase system, together with protein assembly assays and electron microscopical studies provided clues on the protein-protein associations(More)
