چکیده

Tau is a microtubule-associated protein whose misfolding, hyper-phosphorylation, loss of normal function and toxic gain of function are linked to several neurodegenerative disorders, including Alzheimer's disease (AD). This review discusses the role of tau in amyloid-β (Aβ) induced toxicity in AD. The consequences of tau dysfunction, starting from the axon and concluding at somadendritic compartments, will be highlighted.

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 ...

P 62: Markers of Neuroinflammation Related to Alzheimer\'s Disease Pathology in the Elderly

Alzheimer Disease (AD) is a neurodegenerative disorder and the most common form of dementia. Increasing evidence suggests that Alzheimer's disease pathogenesis is not restricted to the neuronal compartment, but includes strong interactions with immunological mechanisms in the brain. In vitro and animal studies have linked neuroinflammation to Alzheimer's disease (AD) pathology. Studies on marke...

P 97: Neurodegeneration Induced by Tau protein

Tau is one of several types of microtubule-associated proteins (MAPs), responsible for the assembly and stability of microtubule networks that is present only in neurons and predominantly localized in axons which its functions are tightly regulated by phosphorylation. Via as yet unknown mechanisms, tau becomes hyperphosphorylated and accompanies with neuronal degeneration, loss of synapses...

Alteration in the Expression of Alzheimer's-Related Genes in Rat Hippocampus by Exercise and Morphine Treatments

Introduction: Alzheimer's disease is a progressive brain disorder, which slowly eliminates memory and intellectual ability and eventually destroys the ability to carry out the simple tasks. β amyloid plaque and neurofibrillary tangles are two important signatures of this disease, which caused by mutant in Tau, BACE1, and APP genes. They could be important targets for treatment of Alzheimer's di...

Zataria multiflora could improve hippocampal tau protein and TNFα levels and cognitive behavior defects in a rat model of Alzheimer's disease

Objective: Zataria multiflora (ZM) is a plant with ethnopharmacological value which was recently tested to reduce symptoms of Alzheimer’s disease (AD). The aim of the present study was to determine the effect of ZM essential oil on spatial cognitive and noncognitive behavior, as well as hippocampal tau protein and tumor necrosis factor alpha (TNFα) concentrations in ra...
