Neuroprotective and cognitive benefits of Semaglutide: Insights into the underlying molecular mechanisms

4 months 3 weeks ago
Neuronal injury is a common complication in patients with diabetes. These injuries include a wide range of neurobehavioral complications that significantly reduce the neuronal network efficiency and quality of life in affected individuals. Currently, diabetes-induced neuronal complications are a major global health challenge, and many studies have been performed to prevent or slow their progression. Semaglutide is a novel form of glucagon-like peptide-1 (GLP-1) agonist agents that has recently...

Unraveling Alzheimer's complexity with a distinct Abeta(42) fibril type and specific AV-45 binding

4 months 3 weeks ago
Abnormal aggregation of amyloid-β protein (1-42) (Aβ(42)) is the primary pathology in Alzheimer's disease (AD). Two types of Aβ(42) fibrils have been identified in the insoluble fraction of diseased human brains. Here, we report that the fraction previously deemed 'soluble' during sarkosyl extraction of AD brains actually harbors numerous amyloid fibrils, with a looser bundling than those in the insoluble fraction. Using cryo-electron microscopy (cryo-EM), we discover a third type (type III) of...
