چکیده

In this report, we reasoned that non-covalent modification of amyloid beta (Aβ) by crown ethers could inhibit its aggregation. We demonstrated that PiB-C, a conjugate PiB and crown ether, could significantly reduce the aggregation in vitro. Additionally, two-photon imaging showed that PiB-C could efficiently label Aβ plaques and CAAs in AD mice.

P135: The Role of Amyloid Beta-Peptides and Tau Protein in Alzheimer\'s Disease

Alzheimer's desease is the most common age-related neurodegenerative disorder, and cognitive problems such as defects in learning and memory are of its symptoms.  Among the factors involved in the pathogenesis of the disease are biochemical disorders in protein production, oxidative stress, decreased acetylcholine secretion and inflammation of the brain tissue. Extra-neuronal accumulation ...

Research Paper: The Effect of Callistephin on Amyloid Beta-Induced Neurotoxicity in the Hippocampus of Male Rats

Introduction: Oxidative stress plays a key role in the pathophysiology of the Alzheimer's disease and it seems that antioxidants may slow the progress of the disease. The current study aimed at investigating the possible protective effects of callistephin (a natural flavonoid) against amyloid β (Aβ)-induced neurogenesis deficits in rats. Methods: Adult Wistar male rats in the current...

The Effect of Endurance Training on the Expression of PRDX6 and KAT2B Genes in Hippocampus of Beta Amyloid-Induced Rat Model of Alzheimer's Disease: An Experimental Study

Background and Objectives: Alzheimer's disease is the most common form of dementia. KAT2B (Lysine Acetyltransferase 2B) is a mitochondrial protein known as mitochondria clearing control organ by mitophagy. PRDX6 (Peroxiredoxin 6) is a key regulator of mitophagy and plays a critical role in maintaining mitochondrial ROS (Reactive oxygen species) homeostasis. Therefore, the purpose of this study ...

Involvement of TRPM7 calcium channels and PI3K/AKT kinase pathway in protective effect of vascular endothelial growth factor in amyloid beta-induced model of Alzheimer’s disease

Background and Objective: Alzheimer’s disease (AD) is a progressive neurodegenerative disorder, in which cortical and hippocampus neurons death is the main target of neurodegeneration. In addition to extracellular beta amyloid accumulation and the production of neural tangles, one of effective factors in the pathology of Alzheimer's disease is vascular injury in the elderly including disturbanc...
