Amyloid precursor protein cleavage through β- and γ-secretases produces β-amyloid peptide, which is believed to be responsible for death of neurons and dementia in Alzheimer’s disease. Levels of β- and γ-secretase are increased in sensitive areas of the Alzheimer’s disease brain, but the mechanism of this process is unknown. In this review, we prove that(More)
The study of sporadic Alzheimer’s disease etiology, now more than ever, needs an infusion of new concepts. Despite ongoing interest in Alzheimer’s disease, the basis of this entity is not yet clear. At present, the best-established and accepted “culprit” in Alzheimer’s disease pathology by most scientists is the amyloid, as the main molecular factor(More)
Autophagy is a major intracellular degeneration pathway involved in the elimination and recycling of damaged organelles and long-lived proteins by lysosomes. Many of the pathological factors, which trigger neurodegenerative diseases, can perturb the autophagy activity, which is associated with misfolded protein aggregates accumulation in these disorders.(More)
The interaction between brain ischemia and Alzheimer's disease (AD) has been intensively investigated recently. Nevertheless, we have not yet understood the nature and mechanisms of the ischemic episodes triggering the onset of AD and how they influence its slow progression. The assumed connection between brain ischemia and the accumulation of amyloid-β(More)
UNLABELLED Anaemia of prematurity (AOP) is caused by a deficiency of erythropoietin, which stimulates differentiation, and growth of erythroid progenitors. The previous standard of therapy of AOP was erythrocyte transfusions. Following successful clinical trials using recombinant human eryrthropoietin (rHuEpo) to treat adults, the rHuEpo has been used to(More)
BACKGROUND Brain ischemia may be causally related with Alzheimer's disease. Probably, presenilin gene dysregulation may be associated with Alzheimer's disease neuropathology. Consequently, we have examined quantitative changes in both presenilin 1 and 2 genes in the medial temporal lobe cortex following 10-min global brain ischemia in rats. METHODS Global(More)
Brain ischemia may be causally related with Alzheimer's disease. Presumably, β-secretase and amyloid-β protein precursor gene expression changes may be associated with Alzheimer's disease neuropathology. Consequently, we have examined quantitative changes in both β-secretase and amyloid-β protein precursor genes in the medial temporal lobe cortex with the(More)
For thousands of years, humankind has used plants for therapeutics. Nowadays, there is a renewed public interest in naturally occurring treatments with minimal toxicity and diets related to health. Alterations in hippocampal neurogenesis have been recognized as an integral part of brain ischemia. Neuronal stem/progenitor cells in the hippocampus are(More)
