WebMay 2, 2024 · The findings may lead to strategies that could help detect the condition early. For years, researchers have known that amyloid-β and tau pathologies, the hallmarks of Alzheimer’s disease, can cause the death of neurons — the brain’s most abundant cells — which eventually leads to impairment and dementia. “But we did not know how the ... WebSep 1, 2024 · Dr Claire Durrant at the University of Edinburgh will investigate the role of tau, a key protein implicated in both frontotemporal dementia and Alzheimer’s disease. Over the five-year project, Dr Durrant will investigate the role of tau in keeping synapses – the connections between brain cells - healthy and how this changes in Alzheimer’s ...

WebFeb 14, 2024 · Alzheimer’s disease (AD) is a neurodegenerative disease that causes memory loss, cognitive decline, and eventually dementia. The etiology of AD and its pathological mechanisms remain unclear due to its complex pathobiology. At the same time, the number of patients with AD is increasing worldwide. However, no therapeutic agents … WebBeta-amyloid in Alzheimer's disease. Alzheimer's disease is characterized by the presence of neurotoxic Aβ plaques in the brain. These plaques are formed by monomeric Aβ spontaneously assembling into soluble oligomers, which cluster together to form insoluble fibrils. Evidence suggests a role for both soluble oligomers and insoluble fibrils ... jean\\u0027s n6
