Download or read book Antimicrobial Peptides in Gastrointestinal Diseases written by Chi Hin Cho and published by Academic Press. This book was released on 2018-06-06 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antimicrobial peptides (AMPs), including cathelicidins and defensins are host defence peptides that carry out multiple roles in the gastrointestinal (GI) tract. Antimicrobial Peptides in Gastrointestinal Diseases presents knowledge about the physiological functions and pharmacological actions of AMPs in inflammation, cancer, and further infection of the GI tract. The book provides coverage from the basic research to clinical application for GI diseases. Current research and development of AMPs is presented, opening the way for further work on these peptides, not only in the context of GI diseases, but also for similar pathologies in other organs. AMPs are key to the regulation of human microbiome and second line defence in the GI mucosa, prevent colonization of pathogens and modulation of innate response to invading pathogens, and modify immunological reactions during inflammatory processes and oncogenic development in the GI mucosa. More importantly, AMPs possess diversified anti-microbial actions against various infectious diseases in the GI tract. With these physiological functions and pharmacological actions, AMPs have significant potential as therapeutic agents for the treatment of inflammation, cancer and further infection in the GI tract. Provides an overview of AMPs, particularly cathelicidin and defensin, in different diseases Covers inflammation and ulcer repair in the stomach and colon and carcinogenesis in the GI tract Presents AMP information and knowledge in a concise manner Gives useful information on all aspects of AMPs Promotes research on AMPs and their development as drugs, from bench, to clinical application
Book Synopsis Antimicrobial Peptides by : Jürgen Harder
Download or read book Antimicrobial Peptides written by Jürgen Harder and published by Springer. This book was released on 2015-12-24 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the importance of human antimicrobial peptides (AMP) in keeping the host healthy and preventing infectious diseases. The first chapters deal with several examples of the role of AMP in different epithelial organs (skin and wound healing, eye, lung, genito-urinary tract, gut), which are exposed to different kinds of infectious microorganisms and as a result produce different patterns of AMP. Examples of the dysregulation of AMP expression and function promoting infections are discussed. The capacity of AMP to restrict the availability of essential metals to bacteria as an efficient antibacterial strategy in nutritional immunity is discussed in the next chapter. Our current understanding of how vitamin D, the sunshine vitamin, influences AMP-expression and how this can affect our health is also addressed. Last but not least, the role of AMP in HIV infection and the immunomodulatory properties of AMP highlight the diverse facets of AMP in host immunity. AMP’s specific functions, including in fighting multi-resistant bacteria, suggest that they may offer therapeutic benefits – a question that is discussed in the final chapter.
Book Synopsis Antimicrobial Peptides and Innate Immunity by : Pieter S. Hiemstra
Download or read book Antimicrobial Peptides and Innate Immunity written by Pieter S. Hiemstra and published by Springer Science & Business Media. This book was released on 2013-02-01 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antimicrobial peptides have been the subject of intense research in the past decades, and are now considered as an essential part of the defense system in bacteria, plants, animals and humans. his book provides an update on these effector molecules of the innate immune system both for researchers who are already actively involved in the area, and for those with a general interest in the topic. The book starts with an overview of the evolution of cysteine-containing antimicrobial peptides (including defensins), and the role of these peptides in host defense in plants and micro-organisms. The realization that antimicrobial peptides also display functions distinct from their direct antimicrobial action is the focus of the next chapters, and puts these peptides center stage in immunity and wound repair. Further chapters discuss the role of antimicrobial peptides in disease, by providing an overview of mechanisms in bacterial resistance to antimicrobial peptides and a discussion of their role in inflammatory bowel disease, cystic fibrosis lung disease and chronic obstructive pulmonary disease. Finally, the book shows how knowledge of the function of antimicrobial peptides and their regulation can be used to design new therapies for inflammatory and infectious disorders. This is a very important area of research because of the increase in resistance of micro-organisms to conventional antibiotics. Therefore the use of synthetic or recombinant peptides, or agents that stimulate the endogenous production of antimicrobial peptides, provides an attractive alternative for conventional antibiotics.
Download or read book Lasso Peptides written by Yanyan Li and published by Springer. This book was released on 2014-10-21 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasso peptides form a growing family of fascinating ribosomally-synthesized and post-translationally modified peptides produced by bacteria. They contain 15 to 24 residues and share a unique interlocked topology that involves an N-terminal 7 to 9-residue macrolactam ring where the C-terminal tail is threaded and irreversibly trapped. The ring results from the condensation of the N-terminal amino group with a side-chain carboxylate of a glutamate at position 8 or 9, or an aspartate at position 7, 8 or 9. The trapping of the tail involves bulky amino acids located in the tail below and above the ring and/or disulfide bridges connecting the ring and the tail. Lasso peptides are subdivided into three subtypes depending on the absence (class II) or presence of one (class III) or two (class I) disulfide bridges. The lasso topology results in highly compact structures that give to lasso peptides an extraordinary stability towards both protease degradation and denaturing conditions. Lasso peptides are generally receptor antagonists, enzyme inhibitors and/or antibacterial or antiviral (anti-HIV) agents. The lasso scaffold and the associated biological activities shown by lasso peptides on different key targets make them promising molecules with high therapeutic potential. Their application in drug design has been exemplified by the development of an integrin antagonist based on a lasso peptide scaffold. The biosynthesis machinery of lasso peptides is therefore of high biotechnological interest, especially since such highly compact and stable structures have to date revealed inaccessible by peptide synthesis. Lasso peptides are produced from a linear precursor LasA, which undergoes a maturation process involving several steps, in particular cleavage of the leader peptide and cyclization. The post-translational modifications are ensured by a dedicated enzymatic machinery, which is composed of an ATP-dependent cysteine protease (LasB) and a lactam synthetase (LasC) that form an enzymatic complex called lasso synthetase. Microcin J25, produced by Escherichia coli AY25, is the archetype of lasso peptides and the most extensively studied. To date only around forty lasso peptides have been isolated, but genome mining approaches have revealed that they are widely distributed among Proteobacteria and Actinobacteria, particularly in Streptomyces, making available a rich resource of novel lasso peptides and enzyme machineries towards lasso topologies.

Book Synopsis Antimicrobial Peptides in Human Health and Disease by : Richard L. Gallo
Download or read book Antimicrobial Peptides in Human Health and Disease written by Richard L. Gallo and published by Taylor & Francis. This book was released on 2005 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a cutting edge summary of one of the most important fields in innate immunity. Antimicrobial peptides rapidly and directly inhibit infection by microbes and are of enormous importance in the body's natural defence against disease. In addition the role of antimicrobial peptides in the development of therapeutic agents for the prevention and treatment of disease is becoming increasingly important. Written by the leaders in the field this book provides an understanding of the implications of antimicrobial peptides in human disease. The volume is divided into sections containing reviews of specific families of antimicrobials, select organ systems that have demonstrated a relevance for antimicrobial peptides and, in addition, a more global discussion of these peptides and organs from distinct perspectives. Alternatively, each chapter can stand on its own, providing the reader with the ability to dive right into the subject of most interest. Topics covered include cathelicidins, alpha and beta defensins, granulysin, hepcidin, the role of antimicrobial peptides in blood, gut, skin, lung and in the oral environment. A recurring theme is the possibility of creating therapeutics that induce the expression of endogenous antimicrobial peptides for the prevention or treatment of disease.

Book Synopsis Nanostructures for Antimicrobial Therapy by : Anton Ficai
Download or read book Nanostructures for Antimicrobial Therapy written by Anton Ficai and published by Elsevier. This book was released on 2017-05-29 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanostructures for Antimicrobial Therapy discusses the pros and cons of the use of nanostructured materials in the prevention and eradication of infections, highlighting the efficient microbicidal effect of nanoparticles against antibiotic-resistant pathogens and biofilms. Conventional antibiotics are becoming ineffective towards microorganisms due to their widespread and often inappropriate use. As a result, the development of antibiotic resistance in microorganisms is increasingly being reported. New approaches are needed to confront the rising issues related to infectious diseases. The merging of biomaterials, such as chitosan, carrageenan, gelatin, poly (lactic-co-glycolic acid) with nanotechnology provides a promising platform for antimicrobial therapy as it provides a controlled way to target cells and induce the desired response without the adverse effects common to many traditional treatments. Nanoparticles represent one of the most promising therapeutic treatments to the problem caused by infectious micro-organisms resistant to traditional therapies. This volume discusses this promise in detail, and also discusses what challenges the greater use of nanoparticles might pose to medical professionals. The unique physiochemical properties of nanoparticles, combined with their growth inhibitory capacity against microbes has led to the upsurge in the research on nanoparticles as antimicrobials. The importance of bactericidal nanobiomaterials study will likely increase as development of resistant strains of bacteria against most potent antibiotics continues. - Shows how nanoantibiotics can be used to more effectively treat disease - Discusses the advantages and issues of a variety of different nanoantibiotics, enabling medics to select which best meets their needs - Provides a cogent summary of recent developments in this field, allowing readers to quickly familiarize themselves with this topic area
Book Synopsis Antimicrobial Peptides by : Katsumi Matsuzaki
Download or read book Antimicrobial Peptides written by Katsumi Matsuzaki and published by Springer. This book was released on 2019-04-12 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of antimicrobial peptides (AMPs), their mechanisms of antimicrobial action, other activities, and various problems that must still be overcome regarding their clinical application. Divided into four major parts, the book begins with a general overview of AMPs (Part I), and subsequently discusses the various mechanisms of antimicrobial action and methods for researching them (Part 2). It then addresses a range of activities other than antimicrobial action, such as cell penetration, antisepsis, anticancer, and immunomodulatory activities (Part 3), and explores the prospects of clinical application from various standpoints such as the selective toxicity, design, and discovery of AMPs (Part 4). A huge number of AMPs have been discovered in plants, insects, and vertebrates including humans, and constitute host defense systems against invading pathogenic microorganisms. Consequently, many attempts have been made to utilize AMPs as antibiotics. AMPs could help to solve the urgent problem of drug-resistant bacteria, and are also promising with regard to sepsis and cancer therapy. Gathering a wealth of information, this book will be a bible for all those seeking to develop antibiotics, anti-sepsis, or anticancer agents based on AMPs.
