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 Toxoplasma Gondii Host Interactions A Story of Immune Attack and Parasite Counterattack written by Jeroen P. J. Saeij and published by Frontiers Media SA. This book was released on 2020-08-10 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxoplasma gondii is an obligate intracellular parasite that can infect all warm-blooded animals, including an estimated ~30% of humans. It can cause severe disease in immune-suppressed individuals and in fetuses as well as blinding chorioretinitis in adults and children. Toxoplasma-innate immune system interactions determine early parasite control and activation of the adaptive immune system by the host and are therefore critical in determining host survival during the acute phase of infection. However, induction of an exaggerated inflammatory response can also lead to pathology. Only the chronic tissue cyst form of Toxoplasma is orally infectious. It is therefore critical for the parasite’s survival during the chronic phase to escape immune responses at this stage as well. Toxoplasma exists as genetically divergent strains mostly depending on geography, with the most strain diversity being found in South America. The key to Toxoplasma’s successful co-option of the host are proteins secreted from its rhoptry and dense granule secretory organelles. Rhoptry proteins (ROPs) are secreted into the host cell cytoplasm upon invasion while dense granule proteins (GRAs) are secreted once the parasite establishes itself in its parasitophorous vacuole (PV). GRAs can localize to the PV, the PV membrane, or are secreted beyond the PVM into the host cytoplasm. Many ROPs and GRAs are involved in modulating host cell signaling pathways and evasion of host immune responses and play important roles in Toxoplasma virulence. Polymorphisms in Toxoplasma’s ROPs and GRAs, likely determine how well these effectors bind to the divergent substrates in different host species, which can explain Toxoplasma strain differences in virulence in a particular host species. By studying Toxoplasma we have not only started to unravel how the parasite modulates immune responses to enhance its survival, replication, and transmission but we have also learned a lot about the immune system. Many unique mechanisms of immunity have indeed been defined using Toxoplasma and this parasite has aided our understanding of tissue-specific immune responses in the brain and intestine. This Research Topic will give a comprehensive overview of Toxoplasma-host immune response interactions. Most Toxoplasma virulence determinants to date have been established in murine systems and it is unclear how the parasite interacts with other intermediate hosts and humans. In addition, the interactions of Toxoplasma with some of the most relevant cell types during infection, including dendritic cells, neurons, intestinal epithelial cells or vascular endothelial cells, remain poorly understood.

Available in PDF, EPUB and Kindle. Book excerpt: Fast inhibitory transmission exerts a powerful control on neuronal excitability and network oscillations thought to be associated with high cognitive functions. An alteration of inhibitory signaling is associated with major neurological and psychiatric disorders including epilepsy. Once released from presynaptic nerve terminals, GABA and glycine cross the synaptic cleft and bind to postsynaptic receptors localized in precise apposition to presynaptic release sites. The functional organization of inhibitory synapses consists in a dynamic process which relies on a number of highly specialized proteins that ensure the correct targeting, clustering, stabilization and subsequent fate of synaptic receptors. Among the proteins involved in this task, the tubulin-binding protein gephyrin plays a crucial role. Through its self-oligomerization properties, this protein forms hexagonal lattices that trap GABAA and glycine receptors and link them to the cytoskeleton. By directly interacting with cell-adhesion molecules of the neuroligin-neurexin families that connect presynaptic and postsynaptic neurons at synapses, gephyrin ensures a backward control of presynaptic signaling. In addition, changes in clusters size is dynamically regulated by lateral diffusion of neurotransmitter receptors between the synaptic and extrasynaptic compartments and by their interaction with synaptic scaffold proteins. The aim of this Research Topic (research articles and reviews) is to bring together experts on the cellular and molecular mechanisms regulating the appropriate assembly, location and function of pre and postsynaptic specializations at inhibitory synapses. A particular emphasis will be on the role of receptor trafficking in synaptic stabilization and plasticity.
