Alzheimer neurofibrillary tangles contain phosphorylated and hidden neurofilament epitopes.
Three monoclonal antibodies to neurofilaments (RT97, BF10 and 147), two of which also recognised neurofibrillary tangles (RT97 and BF10), have all been shown to be specific for phosphorylated epitopes. Treatment of histological sections with alkaline phosphatase prior to immunostaining resulted in reduction of axonal neurofilament staining with all three whilst the neurofibrillary tangles stain...
متن کاملPhosphorylated neurofilament antigens in neurofibrillary tangles in Alzheimer's disease.
Neurofibrillary tangles (NFT) are a hallmark of Alzheimer's disease (AD), and their presence correlates with the presence of dementia. A major constituent of NFT is the insoluble paired helical filament which shares some antigenic relationships with normal cytoskeletal elements, particularly neurofilaments. If neurofilament proteins (200, 145-160, and 68 kilodaltons [kd]) participate in the for...
متن کاملPassive immunization with Tau oligomer monoclonal antibody reverses tauopathy phenotypes without affecting hyperphosphorylated neurofibrillary tangles.
Recent findings suggest that tau oligomers, which form before neurofibrillary tangles (NFTs), are the true neurotoxic tau entities in neurodegenerative tauopathies, including Alzheimer's disease (AD). Studies in animal models of tauopathy suggest that tau oligomers play a key role in eliciting behavioral and cognitive impairments. Here, we used a novel tau oligomer-specific monoclonal antibody ...
متن کاملNeurofibrillary tangles of Alzheimer disease share antigenic determinants with the axonal microtubule-associated protein tau (tau)
The relationship of the neurofibrillary tangle, found in Alzheimer disease and aged brains, to normal or abnormal cytoskeletal proteins remains elusive. Although immunohistochemical studies have yielded disparate results, most antigenic determinants localized to neurofibrillary tangles are cytoskeletal constituents normally present in neuronal perikarya or dendrites. We report light and electro...
متن کاملRecognition of tau epitopes by anti-neurofilament antibodies that bind to Alzheimer neurofibrillary tangles.
Eleven anti-neurofilament (anti-NF) monoclonal antibodies were studied for their reactivity with heat-stable, microtubule-associated proteins and Alzheimer neurofibrillary tangles (ANT). On immunoblots of NF proteins, the antibodies recognized epitopes that were variably sensitive to Escherichia coli alkaline phosphatase. Eight of the antibodies showed reactivity with ANT and decreased binding ...
