Reductions in circulating estrogens can contribute to cognitive decline, in part by impairing mitochondrial function within the hippocampal region. The entorhinal cortex provides the hippocampus with its main cortical input and, to assess the impact of estrogen deficiency on mitochondrial respiration and synaptic proteins in the entorhinal cortex, wildtyp ...

The existing literature on neurodegenerative diseases (NDDs) reveals a common pathological feature: the accumulation of misfolded proteins. However, the heterogeneity in disease onset mechanisms and the specific brain regions affected complicates the understanding of the diverse clinical manifestations of individual NDDs. Dementia, a hallmark symptom acro ...

Although there have been reports indicating that Datura Stramonium (D. stramonium) may induce anticholinergic and neuropsychiatry effects, the compound is still being used for recreational and medicinal purposes while ingestion during pregnancy has been documented. Intriguingly, minimal studies have investigated the potential neurotoxic impact of D. stram ...

Increasing evidence suggests that mitochondrial dysfunction and aberrant release of mitochondrial reactive oxygen species (ROS) play crucial roles in early synaptic perturbations and neuropathology that drive memory deficits in Alzheimer's disease (AD). We recently showed that solubilized human amyloid beta peptide 1-42 (hAß1-42) causes rapid alterati ...

Estrogens are thought to contribute to cognitive function in part by promoting the function of basal forebrain cholinergic neurons that project to the hippocampus and cortical regions including the entorhinal cortex. Reductions in estrogens may alter cognition by reducing the function of cholinergic inputs to both the hippocampus and entorhinal cortex. In ...

The hippocampus and entorhinal cortex (EC) accumulate amyloid beta peptides (Aß) that promote neuropathology in Alzheimer's disease, but the early effects of Aß on excitatory synaptic transmission in the EC have not been well characterized. To assess the acute effects of Aß1-42 on glutamatergic synapses, acute brain slices from wildtype rats were expo ...

Despite reports that quinoline antimalarials including chloroquine (Chq) exhibit idiosyncratic neuropsychiatric effects even at low doses, the drug continues to be in widespread use during pregnancy. Surprisingly, very few studies have examined the potential neurotoxic action of Chq exposure at d ...

The entorhinal cortex (EC) is a vital component of the medial temporal lobe, and its contributions to cognitive processes and memory formation are supported through its extensive interconnections with the hippocampal formation. During the pathogenesis of Alzheimer's disease (AD), many of the earliest degenerative changes are seen within the EC. Neurod ...

The hallmarks of Alzheimer's disease (AD) pathology include senile plaques accumulation and neurofibrillary tangles, which is thought to underlie synaptic failure. Recent evidence however supports that synaptic failure in AD may instead be instigated by enhanced N-methyl-D-aspartate (NMDA) ac ...
