WebTau oligomers are considered pathologic forms of the protein able to initiate specific protein accumulation diseases, called tauopathies. In our study, we investigated the potential … WebExamination of these tau oligomers by transmission electron microscopy or AFM revealed a spherical morphology . This unique method of producing tau oligomers is a reasonable representative model supporting the amyloid hypothesis (36, 37), in which Aβ oligomers trigger NFT formation.
WebOct 21, 2015 · In the present study, tau oligomers were shown to be capable of entering human neurons and triggering the formation of aggregated and hyperphosphorylated pathological tau. These effects were associated with long-term defects in neurite outgrowth, synaptic loss, neuronal loss, abnormal neurotransmission, and intracellular calcium … WebTau is a highly soluble microtubule-associated protein that acts within neurons to modify microtubule stability. However, abnormally phosphorylated tau dissociates from microtubules to form oligomers …

WebTau oligomers are neurotoxic when applied extracellularly to cultured neuronal cells, and tau oligomers (but not fibrils) induce neurodegeneration and synaptic and mitochondrial dysfunction in vivo. Moreove, researchers are able to use tau oligomers as a reliable biomarker to differentiate AD brains from age-matched non-AD brains. Specificity
