Reversibility of Aβ oligomer neurotoxicity
Patients with Alzheimer’s disease (AD), the most common neurodegenerative dementia disorder, chiefly suffer from impairment of memory and other cognitive functions. AD is neuropathologically characterized by senile plaques and neurofibrillary tangles, which are composed of amyloid β-protein (Aβ) and phosphorylated tau proteins, respectively. Recently, a new concept has emerged: that soluble oli...
متن کاملCopper inducing Aβ42 rather than Aβ40 nanoscale oligomer formation is the key process for Aβ neurotoxicity.
Copper is known to be a critical factor in Alzheimer's disease (AD) pathogenesis, as it is involved in amyloid-β (Aβ) peptide related toxicity. However, the relationship between neurotoxicity and Aβ peptide in the presence of copper remains unclear. The effect of copper has not been clearly differentiated between Aβ42 and Aβ40, and it is still debated whether copper-mediated neurotoxicity is du...
متن کاملOptimized-SopungSunkiwon, a Herbal Formula, Attenuates Aβ Oligomer-Induced Neurotoxicity in Alzheimer's Disease Models
Alzheimer's disease (AD), the most common form of dementia, is an age-related neurodegenerative disease that is characterized by memory dysfunction, neuronal cell damage, and neuroinflammation. It is believed that AD-related pathology is mostly due to the overproduction of Aβ, especially the oligomeric form (AβO), in the brain. Evidence of the effects of multifunctional medicinal herbs in the t...
متن کاملElucidating Molecular Mass and Shape of a Neurotoxic Aβ Oligomer
Alzheimer's disease (AD), the most prevalent type of dementia, has been associated with the accumulation of amyloid β oligomers (AβOs) in the central nervous system. AβOs vary widely in size, ranging from dimers to larger than 100 kDa. Evidence indicates that not all oligomers are toxic, and there is yet no consensus on the size of the actual toxic oligomer. Here we used NU4, a conformation-dep...
متن کاملRPS23RG1 reduces Aβ oligomer-induced synaptic and cognitive deficits.
Alzheimer's disease (AD) is the most common form of dementia in the elderly. It is generally believed that β-amyloidogenesis, tau-hyperphosphorylation, and synaptic loss underlie cognitive decline in AD. Rps23rg1, a functional retroposed mouse gene, has been shown to reduce Alzheimer's β-amyloid (Aβ) production and tau phosphorylation. In this study, we have identified its human homolog, and de...
