Book Synopsis Autophagy in Peripheral Neuropathy by : Ayman Osman
Download or read book Autophagy in Peripheral Neuropathy written by Ayman Osman and published by Linköping University Electronic Press. This book was released on 2017-10-23 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peripheral neuropathy includes a wide range of diseases affecting millions around the world, and many of these diseases have unknown etiology. Peripheral neuropathy in diabetes represents a large proportion of peripheral neuropathies. Nerve damage can also be caused by trauma. Peripheral neuropathies are a significant clinical problem and efficient treatments are largely lacking. In the case of a transected nerve, different methods have been used to repair or reconstruct the nerve, including the use of nerve conduits, but functional recovery is usually poor. Autophagy, a cellular mechanism that recycles damaged proteins, is impaired in the brain in many neurodegenerative diseases affecting animals and humans. No research, however, has investigated the presence of autophagy in the human peripheral nervous system. In this study, I present the first structural evidence of autophagy in human peripheral nerves. I also show that the density of autophagy structures is higher in peripheral nerves of patients with chronic idiopathic axonal polyneuropathy (CIAP) and inflammatory neuropathy than in controls. The density of these structures increases with the severity of the neuropathy. In animal model, using Goto-Kakizaki (GK) rats with diabetes resembling human type 2 diabetes, activation of autophagy by local administration of rapamycin incorporated in collagen conduits that were used for reconnection of the transected sciatic nerve led to an increase in autophagy proteins LC3 and a decrease in p62 suggesting that the autophagic flux was activated. In addition, immunoreactivity of neurofilaments, which are parts of the cytoskeleton of axons, was increased indicating increased axonal regeneration. I also show that many proteins involved in axonal regeneration and cell survival were up-regulated by rapamycin in the injured sciatic nerve of GK rats four weeks after injury. Taken together, these findings provide new knowledge about the involvement of autophagy in neuropathy and after peripheral nerve injury and reconstruction using collagen conduits.

Book Synopsis The Role of Wdfy3 in Nervous System Development by : Albert Chi-Kwong Lee (Lee)
Download or read book The Role of Wdfy3 in Nervous System Development written by Albert Chi-Kwong Lee (Lee) and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Autophagy is a cellular process which maintains homeostasis by degradation of unwanted constituents. When autophagy is activated, an autophagosome (a double membraned vesicle) is formed around its target. For autophagy to be selective for its target, it utilizes a combination of autophagosome proteins and target binding proteins. Wdfy3 is a scaffolding protein in the autophagosome that confers target specificity. Wdfy3 gene mutations have been linked to human patients with autism and macro/microcephaly. In addition, Wdfy3 is an evolutionary conserved molecule and has been found to regulate mouse and Drosophila nervous system development. iven Wdfy3's human disease relevance, I investigated Wdfy3's role in Xenopus laevis embryonic and larval nervous system development. I found that Wdfy3 is expressed in the brain and spinal cord of X. laevis larva. In the brain, Wdfy3 is enriched in neurons compared to neural stem cells and localizes both in cell bodies and axons. Knocking down Wdfy3 reveals that it plays a major role in axon outgrowth both in the larval brain and spinal cord. Moreover, in forebrain of embryos deficient in Wdfy3, commissural axonal tracts fail to form, suggesting that Wdfy3 plays an important role in the initial formation and outgrowth of axons. In addition, I found that increasing autophagy levels partially rescues axonal tract formation in Wdfy3 deficient embryos. verall, my findings on Wdfy3 in X. laevis contribute to elucidating Wdfy3's role in nervous system development. Better understanding of Wdfy3's role in neural development could lead to new treatments for autism and macro/microcephaly and potentially other neurodevelopmental disorders that are caused by autophagy dysfunction.
Book Synopsis Polyglutamine Disorders by : Clévio Nóbrega
Download or read book Polyglutamine Disorders written by Clévio Nóbrega and published by Springer. This book was released on 2018-02-09 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a cutting-edge review of polyglutamine disorders. It primarily focuses on two main aspects: (1) the mechanisms underlying the pathologies’ development and progression, and (2) the therapeutic strategies that are currently being explored to stop or delay disease progression. Polyglutamine (polyQ) disorders are a group of inherited neurodegenerative diseases with a fatal outcome that are caused by an abnormal expansion of a coding trinucleotide repeat (CAG), which is then translated in an abnormal protein with an elongated glutamine tract (Q). To date, nine polyQ disorders have been identified and described: dentatorubral-pallidoluysian atrophy (DRPLA); Huntington’s disease (HD); spinal–bulbar muscular atrophy (SBMA); and six spinocerebellar ataxias (SCA 1, 2, 3, 6, 7, and 17). The genetic basis of polyQ disorders is well established and described, and despite important advances that have opened up the possibility of generating genetic models of the disease, the mechanisms that cause neuronal degeneration are still largely unknown and there is currently no treatment available for these disorders. Further, it is believed that the different polyQ may share some mechanisms and pathways contributing to neurodegeneration and disease progression.

Book Synopsis Protein Folding Disorders Of The Central Nervous System by : Jorge A Ghiso
Download or read book Protein Folding Disorders Of The Central Nervous System written by Jorge A Ghiso and published by World Scientific. This book was released on 2017-09-15 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exciting new book explores the dark side of the molecular protein assembly bringing an updated view of how failures in the homeostatic mechanisms that efficiently regulate protein folding leads to the accumulation of structurally abnormal pathogenic assemblies, encompassing an emerging group of diseases collectively known as 'Protein Folding Disorders.' This complex and diverse group of chronic and progressive entities are bridged together by their relationship to structural transitions in the native state of specific proteinaceous components, which for reasons poorly understood, convert into polymeric aggregates that generate poorly soluble tissue deposits and which are considered today the culprit of the disease pathogenesis in their respective diseases. Despite the diversity in the amino acid sequence of the different proteins involved in these heterogeneous disorders, all the pathologic conformers can trigger cascades of events ultimately resulting in cell dysfunction and death with devastating clinical consequences in many of the most precious aspects of human existence including personality, cognition, memory, and skilled movements.This book, which is composed of a compilation of chapters authored by outstanding and well-published scientists in the respective fields currently performing active investigations at world renowned universities and research centers, focuses on the growing number of diseases associated with protein misfolding in the central nervous system. Individual chapters are dedicated to the most common neurodegenerative diseases associated with protein aggregation/fibrillization focusing on the nature of the pathogenic species and the cellular pathways involved in the molecular pathogenesis of Alzheimer's, Parkinson's, and Huntington's diseases as well as in Amyotrophic Lateral Sclerosis, and Prion disorders. A group of contributions is centered on the current knowledge of the intracellular pathways and subcellular organelles affected by the different disease conditions, while others are focused in the emerging pathogenic role of misfolded subunits assembled into neurotoxic soluble oligomers, and in the novel notion of the transmissibility of the protein misfolded species, an innovative concept until recently only accepted for Prion diseases. Lastly, a different set of chapters is dedicated to the evaluation of novel therapeutic strategies for these devastating diseases.

Book Synopsis Membrane Biogenesis by : Jos A.F. Op den Kamp
Download or read book Membrane Biogenesis written by Jos A.F. Op den Kamp and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many individual aspects of the dynamics and assembly of biological membranes have been studied in great detail. Cell biological approaches, advanced genetics, biophysics and biochemistry have greatly contributed to an increase in our knowledge in this field.lt is obvious however, that the three major membrane constituents - lipids, proteins and carbohydrates- are studied, in most cases separately and that a coherent overview of the various aspects of membrane biogenesis is not readily available. The NATO Advanced Study Institute on "New Perspectives in the Dynamics of Assembly of Biomembranes" intended to provide such an overview: it was set up to teach students and specialists the achievements obtained in the various research areas and to try and integrate the numerous aspects of membrane assembly into a coherent framework. The articles in here reflect this. Statting with detailed contributions on phospholipid structure, dynamics, organization and biogenesis, an up to date overview of the basic, lipidic backbone of biomembranes is given. Extensive progress is made in the research on membrane protein biosynthesis. In particular the post- and co-translational modification processes of proteins, the mechanisms of protein translocation and the sorting mechanisms which are necessary to direct proteins to their final, intra - or extracellular destination have been characterized in detail. Modern genetic approaches were indispensable in this research area: gene cloning, hybrid protein construction, site directed mutagenesis and sequencing techniques elucidated many functional aspects of specific nucleic acid and amino acid sequences.
