Synaptic transmission block by presynaptic injection of oligomeric amyloid beta.
Early Alzheimer's disease (AD) pathophysiology is characterized by synaptic changes induced by degradation products of amyloid precursor protein (APP). The exact mechanisms of such modulation are unknown. Here, we report that nanomolar concentrations of intraaxonal oligomeric (o)Abeta42, but not oAbeta40 or extracellular oAbeta42, acutely inhibited synaptic transmission at the squid giant synap...
متن کاملStereotaxic Infusion of Oligomeric Amyloid-beta into the Mouse Hippocampus.
Alzheimer's disease is a neurodegenerative disease affecting the aging population. A key neuropathological feature of the disease is the over-production of amyloid-beta and the deposition of amyloid-beta plaques in brain regions of the afflicted individuals. Throughout the years scientists have generated numerous Alzheimer's disease mouse models that attempt to replicate the amyloid-beta pathol...
متن کاملSelective Amyloid-\(\beta\) Lowering Agents
The amyloid-β peptide (Aβ), implicated in the pathogenesis of Alzheimer's disease (AD), is produced through sequential proteolysis of the Aβ precursor protein (APP) by βand γ-secretases. Thus, blocking either of these two proteases, directly or indirectly, is potentially worthwhile toward developing AD therapeutics. β-Secretase is a membrane-tethered pepsin-like aspartyl protease suitable for s...
متن کاملIL-4-induced selective clearance of oligomeric beta-amyloid peptide(1-42) by rat primary type 2 microglia.
A hallmark of immunopathology associated with Alzheimer's disease is the presence of activated microglia (MG) surrounding senile plaque deposition of beta-amyloid (Abeta) peptides. Abeta peptides are believed to be potent activators of MG, which leads to Alzheimer's disease pathology, but the role of MG subtypes in Abeta clearance still remains unclear. In this study, we found that IL-4 treatme...
متن کاملP 102: The Study of Some Factors Which Effect on Beta-Amyloid Signaling in Neuroinflammation
Neurological inflammatory diseases are developing rapidly. Different factors involved in the pathogenesis of these diseases. In this article, we discuss some of the mechanisms are dealt with. An aberrant procedure of beta-amyloid precursor protein (BAPP) to form neurotoxic beta-amyloid peptides and an accumulated insoluble polymer of beta –amyloid (BA) that forms the senile plaque. The ab...
