Book Synopsis Genetic Variants in Alzheimer's Disease by : Kevin Morgan
Download or read book Genetic Variants in Alzheimer's Disease written by Kevin Morgan and published by Springer Science & Business Media. This book was released on 2013-06-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer’s Disease is the most common form of dementia. The disease is characterised by the loss of synapses and neurons in the cerebral cortex and certain subcortical regions. In the last three years, the genetics of Alzheimer’s Disease has made significant advances; in fact, one could argue more than in the previous two decades. This has resulted in the identification of nine new genes and perhaps more importantly the realization that new pathways could be involved in the pathogenesis of Alzheimer’s. These new pathways are now legitimate targets for therapeutic intervention, which can possibly lead to treatment or a possible cure. The aim of this book is to put all of the recent genetic data on these new genes into context. Different genetic variants will be discussed, as well as biomarkers and future possibilities.

The role of apolipoprotein E in normal brain metabolism and in the pathogenesis of Alzheimer's disease are new and exciting avenues of research. This book, written by the most outstanding scientists in this new filed, is the first presentation of results concerning the implications of apolipoprotein E on the genetics, cell biology, neuropathology, biochemistry, and therapeutic management of Alzheimer's disease.
Book Synopsis Neurodegeneration and Alzheimer's Disease by : Ralph N. Martins
Download or read book Neurodegeneration and Alzheimer's Disease written by Ralph N. Martins and published by John Wiley & Sons. This book was released on 2019-07-10 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the impact of diet, exercise, genetics, and hormones on the risk and development of Alzheimer’s and other neurogenerative diseases Diet is widely known to impact on neurological function. Nevertheless, academic texts discussing this relationship are relatively few in number. This book therefore fills an important gap in the current literature. Opening with an overview of neurodegenerative diseases, particularly Alzheimer’s disease, the text then focuses on explaining the means by which glycemic control and lipid metabolism – and associated nutritional and lifestyle variables – may factor into such disorders’ prevention and treatment. An international group of experts in the fields of food science and neurodegeneration have contributed chapters that examine Alzheimer’s disease within a broad range of contexts. Offering dietary, genetic, and hormonal perspectives, the authors explore topics ranging from sugar consumption to digestive fermentation, and Alzheimer’s disease animal models to the cognition-enhancing effects of physical exercise. Also included are overviews of the latest research into current and developing methods of treatment and diagnosis, as well as differential diagnostics. This groundbreaking book: Explores how glucose metabolism, insulin resistance, lipid metabolism, and high intake of refined carbohydrates are linked to Alzheimer's disease Discusses how genetic makeup can impact risk of Alzheimer’s and Parkinson’s disease Examines cognitive changes in neurodegeneration, lists current tests for determining cognitive impairment, and provides information concerning differential diagnosis Discusses potential advantages of increasing antioxidant and micronutrient intake Reviews hormonal influences on neurodegeneration Examines the links between protein intake and Alzheimer’s disease. Neurodegeneration and Alzheimer's Disease is an essential resource for researchers, medical practitioners, dietitians, and students with an interest in neurological diseases and their diagnosis and risk factors, as well as diet-related conditions such as diabetes and obesity. Lifestyle and diet influence neurodegeneration risk, and a better understanding of this evidence amongst health professionals will hopefully lead to greater public awareness of how to reduce the likelihood of these widespread conditions.

Book Synopsis Identification of Functional Variants in Alzheimer's Disease-associated Genes by : Sheng Chih Jin
Download or read book Identification of Functional Variants in Alzheimer's Disease-associated Genes written by Sheng Chih Jin and published by . This book was released on 2014 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer's disease (AD) is the most common form of dementia affecting the health of more than 5 million Americans in 2013. Understanding how genetic variants contribute to AD is important to develop effective therapeutics for delaying and eventually curing the disease. Recent sequencing studies have identified rare variants p.V232M in PLD3 and p.R47H in TREM2 significantly associated with AD risk. Additionally, genome-wide association studies (GWAS) uncovered common variants in ABCA7, BIN1, CD33, CD2AP, CLU, CR1, EPHA1, MS4A4A, and PICALM that contribute to AD; however, the most-significant variants in these loci are located within non-coding regions and have no direct functional impact on AD pathogenesis. We hypothesized that if PLD3 and TREM2 are truly AD risk genes, they will carry additional functional variants that can substantially affect AD risk. Moreover, we hypothesized that GWAS genes carry additional risk alleles across the frequency spectrum so that common, low frequency or rare variants within these genes may contribute to AD risk. We undertook pooled sequencing of exonic and flanking intronic sequence for the aforementioned genes in 3,730 European Americans (EA) (2,082 AD cases and 1,648 controls) and 336 African Americans (AA) (204 AD cases and 132 controls). We found rare variants in PLD3 and TREM2 are more frequently seen in cases than in controls of EA descent. Single-variant analyses showed that p.M6R and p.A442A in PLD3 and p.R62H in TREM2 are significantly associated with AD risk besides p.V232M in PLD3 and p.R47H in TREM2. We found rare variants in PLD3 (P[subscript SKAT-O]1.44 x 10−11) and TREM2 (P[subscript SKAT-O]5.37 x 10−7) are genome-wide significantly associated with AD. Additionally, we found a significant association for PLD3 coding variants with AD risk in AA (P[subscript SKAT-O]1.40 x 10−3). However, we did not find evidence of association for TREM2 variants with AD risk in AA. We validated 90 coding variants in GWAS-identified genes and bioinformatic analyses implicated that a large proportion of these variants are functional. The International Genomics of Alzheimer's Project recently performed meta- and gene-wide analyses and identified 23 loci associated with AD risk, of which 13 were novel. However, these loci's role in affecting the molecular pathways of AD remains unknown. To determine whether these loci are also associated with cerebrospinal fluid (CSF) amyloid-beta 1-42 (A[beta]42) and phosphorylated tau11 (ptau11) levels, we combined CSF biomarker datasets from several studies and performed single-variant, set-based, and conditional analyses for each locus. In the APOE locus, rs769449 is genome-wide significantly associated with CSFA[beta]42 and ptau11 levels independently of APOE-[epsilon]2 and APOE-[epsilon]4 SNPs and the association for CSF ptau181 levels was not driven by A[beta] metabolism. We found rs7937331, within the CELF1 fine-mapping region, tags the same signal as the IGAP top SNP (rs62003531) and is significantly associated with CSF A[beta]42 levels and AD risk. Additionally, rs62003531, located in the intronic region of FERMT2, tags the same association as the IGAP top SNP (rs17125944) and is associated with CSF A[beta]42 levels. None of the SNPs within the IGAP-identified AD risk loci except the APOE locus are significantly associated with CSF ptau181 levels after multiple test correction. In investigating the potential regulatory functions associated with IGAP top SNPs and CSF top SNPs, most of GWAS top SNPs have no significant regulatory potential and are unlikely to be functional variants for AD risk. However, RegulomeDB predicts that several proxy SNPs in linkage disequilibrium (LD) with rs7937331 may be cis-acting expression quantitative trait loci (eQTLs) for nearby genes. The IGAP study also identified an intergenic polymorphism near TREML2 suggestively associated with AD risk; however, due to the study design, it was not possible to uncover the underlying functional variant or to determine whether this observed association was driven by the known AD risk allele, TREM2 p.R47H, or represented a novel locus. We performed analyses using whole-exome sequencing data, CSF biomarker analyses and meta-analyses to demonstrate that the AD risk association is likely driven by a TREML2 variant p.S144G (rs3747742) independently of TREM2 p.R47H risk for AD. Finally, we sought to functionally characterize the effects of novel TREM2 variants on TREM2 cell surface transport. We transduced a T cell hybridoma cell line with virus containing TREM2 wild type (WT) and risk variants and measured TREM2 cell surface expression with a TREM2-specific monoclonal antibody. We found cells expressing p.T66M and p.R136W have a robust effect on TREM2 cell surface expression but cells expressing p.R47H and p.R62H are similar to hTREM2 WT. Additionally, since polymorphisms in the CELF1 fine-mapping region were implicated to be eQTLs for nearby genes, we performed cis-eQTL analysis for mRNA expression levels in several brain regions using four publicly available datasets to identify genetic determinants of gene expression in human brains. We found several C1QTNF4-expression-associated SNPs which tag the same signal are in LD with rs7937331, the top CSF A[beta]42 SNP in the CELF1 fine-mapping region. Additionally, we found evidence of differential expression in the C1QTNF4 transcript between AD cases and controls in human brains. These findings provide additional evidence that genes involved in the inflammatory response play an important role in AD pathogenesis.

Book Synopsis Frontiers in Psychiatry by : Yong-Ku Kim
Download or read book Frontiers in Psychiatry written by Yong-Ku Kim and published by Springer Nature. This book was released on 2019-11-09 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews key recent advances and new frontiers within psychiatric research and clinical practice. These advances either represent or are enabling paradigm shifts in the discipline and are influencing how we observe, derive and test hypotheses, and intervene. Progress in information technology is allowing the collection of scattered, fragmented data and the discovery of hidden meanings from stored data, and the impacts on psychiatry are fully explored. Detailed attention is also paid to the applications of artificial intelligence, machine learning, and data science technology in psychiatry and to their role in the development of new hypotheses, which in turn promise to lead to new discoveries and treatments. Emerging research methods for precision medicine are discussed, as are a variety of novel theoretical frameworks for research, such as theoretical psychiatry, the developmental approach to the definition of psychopathology, and the theory of constructed emotion. The concluding section considers novel interventions and treatment avenues, including psychobiotics, the use of neuromodulation to augment cognitive control of emotion, and the role of the telomere-telomerase system in psychopharmacological interventions.

Book Synopsis Neurodegeneration by : Dennis Dickson
Download or read book Neurodegeneration written by Dennis Dickson and published by John Wiley & Sons. This book was released on 2011-09-09 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most textbooks on neurodegenerative disorders have used a classification scheme based upon either clinical syndromes or anatomical distribution of the pathology. In contrast, this book looks to the future and uses a classification based upon molecular mechanisms, rather than clinical or anatomical boundaries. Major advances in molecular genetics and the application of biochemical and immunocytochemical techniques to neurodegenerative disorders have generated this new approach. Throughout most of the current volume, diseases are clustered according to the proteins that accumulate within cells (e.g. tau, α-synuclein and TDP-43) and in the extracellular compartments (e.g. β-amyloid and prion proteins) or according to a shared pathogenetic mechanism, such as trinucleotide repeats, that are a feature of specific genetic disorders. Chapters throughout the book conform to a standard lay-out for ease of access by the reader and are written by a panel of International Experts Since the first edition of this book, major advances have been made in the discovery of common molecular mechanisms between many neurodegenerative diseases most notably in the frontotemporal lobar degenerations (FTLD) and motor neuron disease or amyotrophic lateral sclerosis. This book will be essential reading for clinicians, neuropathologists and basic neuroscientists who require the firm up-to-date knowledge of mechanisms, diagnostic pathology and genetics of Neurodegenerative diseases that is required for progress in therapy and management.
