Download or read book The Role of Dietary N 6 Polyunsaturated Fatty Acids on Lipid Mediators and Inflammation in the Mouse Brain written by Shoug Alashmali and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: N-6 polyunsaturated fatty acids (PUFA) such as arachidonic acid (ARA, 20:4) and n-3 PUFA as docosahexaenoic acid (DHA, 22:6) are precursors to bioactive lipid mediators, which have important roles in many brain functions including inflammation. Previous studies have shown that dietary n-6 PUFA deprivation in pups can change brain ARA and DHA levels. However, the effects of n-6 PUFA deprivation on brain lipid metabolism during maternal stage has yet to be studied. Moreover, n-6 PUFA have been linked to the pathogenesis of many neurological disorders through many mechanisms, including conversion to ARA-derived lipid mediators (pro-inflammatory mediators) in the brain. Though diets low in n-6 PUFA are known to reduce levels of ARA and ARA-derived lipid mediators, no one has yet investigated the effects of lowering dietary n-6 PUFA on modulating brain inflammation and resolution in neuroinflammation. The first objective of this thesis was to examine how lowering dietary n-6 PUFA, from gestation, would change levels of hippocampal n-6 and n-3 PUFA and their lipid mediators in comparison to the offspring period. We found that maternal exposure to an n-6 PUFA deprived diet does not exacerbate the reduction in ARA and ARA-derived lipid mediators within hippocampal phospholipids (PL) relative to offspring exposure, which suggests that offspring exposure is a main regulating factor of these PUFA and their derivatives. Therefore, we used the offspring stage as the feeding period for the subsequent neuroinflammation study. Neuroinflammation was induced using intracerebroventricular injection of lipopolysaccharide (LPS) and the hippocampus was examined at several time points. Following LPS, different pro-inflammatory gene expression was associated with enrichment in gene expression categories associated with inflammation. However, these pro-inflammatory markers were not reduced by lowering dietary n-6 PUFA and importantly did not impair the resolution of neuroinflammation. In conclusion, we found that exposure of the offspring to an n-6 PUFA deprived diet was sufficient to lower the concentrations of ARA and other n-6 PUFA in hippocampal total PL. In a neuroinflammation model, the expression in gene ontology categories associated with inflammation was significantly increased and then resolved in response to LPS administration, however, irrespective of an n-6 PUFA diet.

Download or read book Bioactive Lipid Mediators written by Takehiko Yokomizo and published by Springer. This book was released on 2015-10-27 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the most recent progress in the studies of lipid mediators from the molecular to clinical level and introduces newly created tools for analysis including imaging mass spectrometry. Comprising 29 chapters divided into four major parts, the book describes the molecular natures of enzymes, transporters, and receptors for lipid mediators (Part I), the function of lipid mediators in Drosophila and Zebrafish (Part II), the relationships between lipid mediators and various diseases (Part III), and detailed procedures of extraction, preparation, and quantification of lipid mediators (Part IV). Research on lipid mediators initially started with analysis of the action of aspirin, and subsequent biochemical experiments identified many enzymes and receptors responsible for the biosynthesis and signal transduction of individual lipid mediators. Through the phenotypic analyses of transgenic and knockout mice, it has been shown that the dysregulation of some lipid mediators causes inflammatory, immune, or oncogenic disorders. Lipid mediators have attracted increased attention because their structures are conserved among different species, and their biosynthetic and signaling pathways have been deciphered at the molecular level. Many drugs that target lipid mediators are already being used in hospitals, and this book suggests further possibilities for development of a wide variety of such drugs. Very recently, highly sensitive mass spectrometry has begun to be used to identify novel lipid mediators that are present only in trace amounts in tissues but with robust biological activity. Written by international experts, this book provides readers a comprehensive view of lipid mediators and related topics and helps in the process of determining research targets for the near future.

This book was released on 2021 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: The omega-3 fatty acid, docosahexaenoic acid (DHA), is highly enriched in the central nervous system (CNS) and thought to protect against neurological dysfunction. Due to its neuroprotective nature, DHA is widely considered a medicinal preventative strategy and treatment. However, while dietary DHA supplementation increases DHA levels in peripheral tissues, it often fails to increase brain DHA levels. The indirect relationship between dietary-DHA and brain-DHA enrichment highlights the existence of unique mechanisms that allow DHA to be metabolized in the brain. The mechanisms regulating DHA enrichment in the brain remain unclear. The purpose of this dissertation was to answer fundamental questions about the mechanisms that regulate brain DHA metabolism by testing the hypothesis that a specific fatty acid metabolizing enzyme, long-chain acyl-CoA synthetase isoform 6 (ACSL6), is required for enrichment of DHA into the brain. As reviewed in my first-author literature review published in PLEFA in September 2020, ACSL6 is one of a large family of 26 acyl-CoA synthetase (ACS) enzymes that catalyze the initial step in cellular fatty acid metabolism and serve as potential master regulators of brain phospholipid acyl-chain diversity. Of all the ACSs, ACSL6 is almost exclusively expressed in the CNS and has been shown to have substrate preference for DHA. To test our hypothesis, we genetically targeted ACSL6 to create a novel conditional ACSL6-deficient mouse (Acsl6-/-). We discovered that whole-body Acsl6 deletion results in a significant 35-72% reduction in DHA-containing phospholipids in the CNS. Our initial findings for this animal model were published as my first first-author research article in PNAS in October of 2018, and our findings were of such great interest that the article was mentioned on the cover of the issue and was accompanied by a complementary commentary highlighting the importance of our discovery. We then went on to combine in situ fluorescence hybridization, several genetically targeted mouse models, lipidomics, and MALDI lipid imaging to demonstrated that ACSL6 in neurons regulates the enrichment of DHA in the brain. We also have shown that ACSL6 expressed in astrocytes does alter membrane acyl-chain content, but does not impact DHA, which we mechanistically explain is due to cell-type specific expression of ACSL6 variants that contain altered fatty acid binding domains. After many behavioral assessments, we found that ACSL6 knockout mice were hyporesponsive to auditory and foot-shock sensory stimulation, exhibited hyperlocomotion, and showed altered short-term working spatial memory. Acsl6-/- mice displayed exacerbated astrogliosis in an age-dependent manner and accompanied with increased inflammation and gliosis. This neuroinflammation occurred independent of changes in pro- and anti-inflammatory lipid mediators suggesting there is an alternative mechanism triggering the neuroinflammation. RNA-seq data revealed downregulation of synaptic proteins' gene expression in Acsl6-/- mice as early as 2 months of age. Thus, we hypothesized that ACSL6-mediated DHA deficiency results in gradual synaptic function deregulation that contributes to increased neuroinflammation during aging. These age-dependent findings are currently under revisions for publication. Together, these data identified ACSL6 in neurons as an important regulator of DHA metabolism that plays a neuroprotective role during aging and on memory and motor function. This dissertation work has led to the discovery of an important and fundamental mechanism by which the parenchyma of the central nervous system controls fatty acid metabolism, particularly for the neuroprotective omega-3 fatty acid DHA.

Download or read book Lipids in Health and Disease written by Peter Quinn and published by Springer Science & Business Media. This book was released on 2008-08-27 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.
