Amyloid Precursor Protein

چکیده
Intracellular trafficking and proteolytic processing of amyloid precursor protein (APP) have been the focus of numerous investigations over the past two decades. APP is the precursor to the amyloid -protein (A ), the 38–43-amino acid residue peptide that is at the heart of the amyloid cascade hypothesis of Alzheimer disease (AD). Tremendous progress has been made since the initial identification of A as the principal component of brain senile plaques of individuals with AD. Specifically, molecular characterization of the secretases involved inA production has facilitated cell biological investigations on APP processing and advanced efforts to model AD pathogenesis in animal models. This minireview summarizes salient features of APP trafficking and amyloidogenic processing anddiscusses the putative biological functions of APP.

Minocycline blocks c-terminal fragments of amyloid precursor protein-induced neurotoxicity by inhibition of cytochrome c release and caspase-12 activation
Minocycline is a second-generation tetracycline that effectively crosses the blood-brain barrier. It has remarkable neuroprotective qualities in models of cerebral ischaemia, traumatic brain injury, Huntington’s and Parkinson’s diseases. However, there is no evidence about neuroprotective effects of minocycline on AD. Alzheimer’s disease (AD) is a neurodegenerative disorder characterized neurop...

متن کاملInvestigation of the Iron Oxide Nanoparticle Effects on Amyloid Precursor Protein Processing in Hippocampal Cells
Introduction: Iron oxide nanoparticles (Fe2O3-NPs) are small magnetic particles that widely used in different aspects of biology and medicine in modern life. Fe2O3-NP accumulated in the living cells due to absence of active system to excrete the iron ions so damages cellular organelles by highly reactivity. Method: Herein cytotoxic effects of Fe2O3-NP with 50 nm size were investigated on prima...
متن کاملEffect of rosiglitazone on amyloid precursor protein processing and Aβ clearance in streptozotocin-induced rat model of Alzheimer’s disease
Objective(s): Increasing evidence suggests that Alzheimer’s disease (AD) is associated with diabetes. Rosiglitazone, a peroxisome proliferator-activated receptor γ (PPAR-γ) agonist and anti-diabetic agent, may improve symptoms of AD. However, the underlying therapeutic potential of it has not been fully elucidated. Materials and Methods: Rats were divided into four groups: control group, sham o...

Background: Recently, researchers have considered extremely low-frequency electromagnetic fields (ELF-EMFs), as one of the non-invasive therapies, in the treatment of many severe neurological disorders, including Alzheimer Disease (AD). AD is a progressive neurodegenerative disease characterized by the deposition of amyloid plaques in the brain. However, the increase in microglial cells increas...
