Cellular prion protein (PrPC) binds the scrapie conformation of PrP (PrPSc) and oligomeric β-amyloid peptide (Aβo) to mediate transmissible spongiform encephalopathy (TSE) and Alzheimer's disease (AD), respectively. We conducted cellular and biochemical screens for compounds blocking PrPC interaction with Aβo.

This study investigated the in vitro release of vancomycin, gentamicin, and lidocaine from novel electrospun sandwich-structured polylactide-polyglycolide (PLGA)/collagen nanofibrous membranes. For the electrospinning of biodegradable membranes, PLGA/collagen and PLGA/vancomycin/gentamicin/lidocaine were separately dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). They were then electrospun into

In Alzheimer's disease, accumulation of amyloid-β (Aβ) is associated with loss of brain-derived neurotrophic factor (BDNF), synapses, and memory. Previous work demonstrated that Aβ decreases activity-induced BDNF transcription by regulating cyclic adenosine monophosphate response element binding protein (CREB) phosphorylation. However

Alzheimer's disease (AD) symptoms reflect synaptic dysfunction and neuron death. Amyloid-β oligomers (AβOs) induce excess calcium entry into neurons via N-methyl-D-aspartate receptors (NMDARs), contributing to synaptic dysfunction. The study described here tested the hypothesis that AβO-stimulated calcium entry also drives
