The Implication of Androgens in the Presence of Protein Kinase C to Repair Alzheimer’s Disease-Induced Cognitive Dysfunction
Aging, as a major risk factor of memory deficiency, affects neural signaling pathways in hippocampus. In particular, age-dependent androgens deficiency causes cognitive impairments. Several enzymes like protein kinase C (PKC) are involved in memory deficiency. Indeed, PKC regulatory process mediates α-secretase activation to cleave APP in β-amyloid cascade and tau proteins phosphorylation mecha...
متن کاملAlzheimer-associated neuronal thread protein as a novel urine biomark in Alzheimer’s disease
Alzheimer’s disease (AD) is one of the most common and devastating aging related neurodegenerative diseases. The disease poses a great threat to older individuals and their families, becoming a serious social problem with increasing longevity. The clinical manifestation of disease occurs usually after the age of 65 [1]. This illness is characterized by massive neuronal loss, cognitive dysfuncti...

Background and Objective: Alzheimer’s disease (AD) is one of the most common neurodegenerative diseases and results from the extracellular accumulation of b-amyloid peptides and the resulting neuronal dysfunction. In this study, the role of nicotinic acetylcholine receptors, protein kinase B (PKB) and protein kinase M (PKM) were evaluated in order to examine the mechanism of the protective effe...
متن کاملVarenicline Ameliorates Learning and Memory Deficits in Amyloid β(25–35) Rat Model of Alzheimer’s Disease
Introduction: Alzheimer’s disease (AD) is a enfeeble neurodegenerative disorder characterized by increased β-amyloid (Aβ) deposition and neuronal dysfunction leading to impaired learning and recall. Among proposed risk factors, impaired cholinergic transmission is a main cause for incidence of disease. Methods: In the present study, effects of the intracerebroventricularly administration of an ...
متن کاملRosmarinic acid mitigates learning and memory disturbances in amyloid β(25–35)-induced model of Alzheimer’s disease in rat
Abstract Background and Objective: Alzheimer’s disease (AD) is a weakening neurodegenerative disorder typified by increased b-amyloid (Ab) deposition and neuronal dysfunction causing to impaired learning and memory. Among proposed risk factors, induced oxidative stress is a main cause for incidence of the disease. The aim of this study was to determine the effects of the rosmarinic acid on lear...
