Neuroinflammation and oxidative stress have been emerging as important pathways contributing to Parkinson’s disease (PD) pathogenesis. In PD brains, the activated microglia release inflammatory factors such as interleukin (IL)-β, IL-6, tumor necrosis factor (TNF)-α, and nitric oxide (NO), which increase oxidative stress and mediate neurodegeneratio...
Misfolded aggregation of the hyperphosphorylated microtubule binding protein Tau in the brain is a pathological hallmark of Alzheimer’s disease (AD). Tau aggregation downregulates brain-derived neurotrophic factor (BDNF)/tropomycin receptor kinase B (TRKB) signaling and leads to neurotoxicity. Therefore, enhancement of BDNF/TRKB signaling could be...
Alzheimer's disease (AD) is a neurodegenerative disease with progressive memory loss and the cognitive decline. AD is mainly caused by abnormal accumulation of misfolded amyloid β (Aβ), which leads to neurodegeneration via a number of possible mechanisms such as down-regulation of brain-derived neurotrophic factor-tropomyosin-related kinase B (BDNF...
Hyperphosphorylation and aggregation of the microtubule binding protein tau is a neuropathological hallmark of Alzheimer’s disease/tauopathies. Tau neurotoxicity provokes alterations in brain-derived neurotrophic factor (BDNF)/tropomycin receptor kinase B (TRKB)/cAMP-response-element binding protein (CREB) signaling to contribute to neurodegenerati...
Decreased BDNF and impaired TRKB signaling contribute to neurodegeneration in Alzheimer's disease (AD). We have shown previously that coumarin derivative LM-031 enhanced CREB/BDNF/BCL2 pathway. In this study we explored if LM-031 analogs LMDS-1 to -4 may act as TRKB agonists to protect SH-SY5Y cells against Aβ toxicity. By docking computation for b...
Abnormal accumulations of misfolded Aβ and tau proteins are major components of the hallmark plaques and neurofibrillary tangles in the brains of Alzheimer’s disease (AD) patients. These abnormal protein deposits cause neurodegeneration through a number of proposed mechanisms, including downregulation of the cAMP-response-element (CRE) binding prot...
Alzheimer’s disease (AD) is a common neurodegenerative disease presenting with progressive memory and cognitive impairments. One of the pathogenic mechanisms of AD is attributed to the aggregation of misfolded amyloid β (Aβ), which induces neurotoxicity by reducing the expression of brain-derived neurotrophic factor (BDNF) and its high-affinity rec...
Amyloid β (Aβ) plays a major role in the neurodegeneration of Alzheimer's disease (AD). The accumulation of misfolded Aβ causes oxidative stress and inflammatory damage leading to apoptotic cell death. Traditional Chinese herbal medicine (CHM) has been widely used in treating neurodegenerative diseases by reducing oxidative stress and neuroinflamma...
Polyglutamine (polyQ)-mediated spinocerebellar ataxias (SCA) are caused by mutant genes with expanded CAG repeats encoding polyQ tracts. The misfolding and aggregation of polyQ proteins result in increased reactive oxygen species (ROS) and cellular toxicity. Inflammation is a common manifestation of oxidative stress and inflammatory process further...
Microtubule‐associated protein Tau, abundant in the central nervous system (CNS), plays crucial roles in microtubule assembly and stabilization. Abnormal Tau phosphorylation and aggregation are a common pathogenic hallmark in Alzheimer's disease (AD). Hyperphosphorylation of Tau could change its conformation and result in self‐aggregation, increase...
The pathogenesis of Alzheimer's disease (AD) is involved in the aggregation of misfolded amyloid β (Aβ), which upregulates the activity of acetylcholinesterase (AChE), increases the production of reactive oxygen species (ROS), enhances neuroinflammation, and eventually leads to neuronal death. Therefore, compounds targeting these mechanisms may be...
Alzheimer's disease (AD), associated with abnormal accumulation of amyloid-β (Aβ), is the most common cause of dementia among older people. A few studies have identified substantial AD biomarkers in blood but their results were inconsistent. Here we screened gene expression alterations on Aβ-GFP SH-SY5Y neuronal model for AD, and evaluated the find...
Amyloid β (Aβ) plays a major role in the pathogenesis of Alzheimer’s disease (AD). The accumulation of misfolded Aβ causes oxidative and inflammatory damage leading to apoptotic cell death. Chinese herbal medicine (CHM) has been widely used in clinical practice to treat neurodegenerative diseases associated with oxidative stress and neuroinflammati...
Background
Aggregation of misfolded amyloid β (Aβ) in senile plaques causes oxidative stress and neuronal death in Alzheimer's disease (AD). Compounds possessing antiaggregation and antioxidant properties are promising candidate compounds for AD treatment.
Methods
We examined the potential of synthetic derivatives of licochalcone A and coumarin fo...
The multifaceted nature of alcohol as a solvent, nutrient, vessel and urinary tract regulator, blood sugar and neuronal activity suppressor, anxiolytic, addictive substance, teratogen, and common drink throughout history, make it one of the most fascinating molecules of all time. In this review, we will portray an additional image of alcohol as a d...
Alzheimer's disease (AD) is the most prevalent form of dementia associated with progressive cognitive decline and memory loss. Extracellular β-amyloid (Aβ) is a major constituent of senile plaques, one of the pathological hallmarks of AD. Aβ deposition causes neuronal death via a number of possible mechanisms such as increasing oxidative stress. Th...
