Download or read book The Glutamate GABA Glutamine Cycle written by Arne Schousboe and published by Springer. This book was released on 2016-11-25 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental biochemical studies of basic brain metabolism focusing on the neuroactive amino acids glutamate and GABA combined with the seminal observation that one of the key enzymes, glutamine synthetase is localized in astroglial cells but not in neurons resulted in the formulation of the term “The Glutamate-Glutamine Cycle.” In this cycle glutamate released from neurons is taken up by surrounding astrocytes, amidated by the action of glutamine synthetase to glutamine which can be transferred back to the neurons. The conversion of glutamate to glutamine is like a stealth technology, hiding the glutamate molecule which would be highly toxic to neurons due to its excitotoxic action. This series of reactions require the concerted and precise interaction of a number of enzymes and plasma membrane transporters, and this volume provides in-depth descriptions of these processes. Obviously such a series of complicated reactions may well be prone to malfunction and therefore neurological diseases are likely to be associated with such malfunction of the enzymes and transporters involved in the cycle. These aspects are also discussed in several chapters of the book. A number of leading experts in neuroscience including intermediary metabolism, enzymology and transporter physiology have contributed to this book which provides comprehensive discussions of these different aspects of the functional importance of the glutamate-glutamine cycle coupling homeostasis of glutamatergic, excitatory neurotransmission to basic aspects of brain energy metabolism. This book will be of particular importance for students as well as professionals interested in these fundamental processes involved in brain function and dysfunction.

Download or read book Tau oligomers written by Jesus Avila and published by Frontiers E-books. This book was released on 2014-08-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.

Download or read book Epilepsy and Alzheimer s disease shared pathology clinical presentations and targets for treatment written by Beth Leeman-Markowski and published by Frontiers Media SA. This book was released on 2024-09-30 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging data suggest a link between Alzheimer’s disease (AD) and epilepsy. AD and other dementias pose increased risk for seizures, with seizure incidence in AD up to ten times greater than in age-matched controls. Mouse models of AD also demonstrate seizures and abnormal spikes or sharp wave discharges (“interictal epileptiform discharges” [IEDs]) on electroencephalography (EEG). Seizures and IEDs may underlie fluctuating cognitive abilities in AD, with the impact of antiseizure medication (ASM) requiring further investigation. Many epilepsy patients have memory and other cognitive deficits, due to multiple factors. Most adult-onset epilepsy occurs in people =60 years of age, and epilepsy patients are at increased risk of developing dementia. Hyperphosphorylated tau and amyloid deposits were found in resected temporal lobe tissue of epilepsy patients, similar to AD, and increased total and phosphorylated tau levels in the cerebrospinal fluid may predict the onset of AD and other dementias. The mechanisms underlying the associations between AD, epilepsy, tau deposition, and beta amyloid plaques, and their relationships to clinical features, are unknown. Some epilepsy patients develop dementia, and some AD patients develop seizures, while others do not. Analyses of resected tissue in epilepsy patients also suggest variable amyloid and tau deposition across patients and studies. Who is at risk? What does shared pathology indicate regarding disease development, progression, and treatment? Better understanding of the associations between epilepsy and dementia with respect to epidemiology, pathophysiology, genetics, clinical presentations, and treatment approaches based on animal models and human studies is needed to optimize patient care. Insight into the relationship between epilepsy and AD requires various approaches, including tissue analysis, imaging, genetic techniques, cognitive testing, and electroencephalography in animals and humans. We welcome manuscripts that span these approaches, including original research articles, brief research articles, clinical trials, case reports, reviews, systematic reviews, mini-reviews, methods articles, hypothesis and theory articles, perspectives, and opinions. Themes may include: • Diagnosis (e.g., seizure or interictal discharge detection in dementia patients, distinguishing comorbid dementia from epilepsy-related cognitive dysfunction) • Epidemiology (e.g., incidence and prevalence of comorbid AD and epilepsy, occurrence of epilepsy in other dementias, seizure types, age or stage of onset) • Genetic risk factors • Pathophysiology underlying seizure generation in AD and cognitive decline in epilepsy • Treatment approaches (e.g., effects of ASMs on cognitive decline, impact of disease modifying AD treatments on seizures, neurostimulation) • What can be learned from other disorders in which cognitive deficits and seizures are common (i.e., traumatic brain injury)
