Available in PDF, EPUB and Kindle. Book excerpt: Infectious diseases present a significant challenge to public health, and there is an urgent need to develop new strategies to address bacterial and viral pathogenesis. As the initial interaction between pathogen and the host cell is often mediated by a carbohydrate recognition event, a straightforward and effective strategy to prevent infection is to block host-pathogen protein-carbohydrate binding. By mimicking carbohydrate ligands present on the host mucosa, human milk glycans have been proven to function as soluble inhibitors capable of preventing a variety of pathogens from binding to the host. These glycans hold great promise to be employed as anti-infective prophylactics to combat infectious disease in both pediatric and adult populations. However, among the hundreds of carbohydrate structures found in human milk, it is challenging to establish the inhibitory relationship between discrete glycan entities and specific pathogens. To address this problem and accelerate the development of anti-infective glycans, we apply high-throughput and label-free biosensing platforms for characterizing the anti-viral activities of human milk glycans against norovirus and HIV. Surface plasmon resonance (SPR) and silicon photonic microring resonators are two types of label-free biosensors capable of quantifying binding events in real-time. However, the lack of efficient biofunctionalization strategies limits the application of these devices in characterizing carbohydrate-mediated interactions. In this study, reliable and versatile conjugation methods were developed to functionalize biosensors with carbohydrates. These methods utilize a homobifunctional linker, divinylsulfone (DVS), to conjugate natural sugars or carbohydrates modified with nucleophilic linkers ( -NH2, -SH) onto the sensor surface. Compared to previous immobilization strategies, our DVS-based method greatly simplifies the process for carbohydrate immobilization and demonstrates high stability for biosensing. Next, the carbohydrate-functionalized biosensors were applied to study human milk glycan-norovirus interactions. We identified glycans that bind to two strains of norovirus and confirmed the activity of specific glycans against norovirus-host receptor interactions. Finally, the inhibitory mechanism of human milk glycosaminoglycans (GAGs) against HIV infection was investigated by SPR. The biosensing platforms and the binding studies in this dissertation advance our understanding of the anti-infective mechanism of human milk glycans and promote the application of glycan-based agents to prevent norovirus and HIV infection.

Available in PDF, EPUB and Kindle. Book excerpt: This book is unique in providing pertinent information on the various established roles carbohydrate play in the immune system and how the innate and adaptive immune systems respond to this type of microbial antigens. The editors selected only topics that have established basic and clinical relevance to this field. The topics from basic research are organised like a textbook, in order to guide the readers through complex sets of events that lead to clearance of or to immune responses toward carbohydrate antigens. The book is clear, concise and contains fully annotated summaries of the key basic and practical information on carbohydrate immunology from current literature. These topics are written by investigators from various disciplines (chemistry, medicine, biochemistry, glycobiology and immunology), creating a fine balance in the point of views presented in the book. It explores the challenges and rewards of understanding the importance of carbohydrates and glycoconjugates in health and disease, applying new knowledge from carbohydrate immunology in improving or developing novel sugar-based therapeutics, and vaccines and medicines. This book is most suitable for glycobiologists and immunologists, but many researchers whose interests, background and expertise are in any of the fifteen topics presented in this book will also find it appealing. It is also a valuable resource for postgraduate students, clinicians or anyone else who is curious about the role of carbohydrates in immunology, and would like to see the topics combined under one cover and in relation to each other.
Download or read book Carbohydrate based Vaccines written by René Roy and published by ACS Symposium. This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of its kind entirely dedicated to carbohydrate vaccines written by renowned scientists with expertise in carbohydrate chemistry and immunochemistry. It covers the synthesis of carbohydrate antigens related to bacteria and parasites such as: Heamophilus influenza, Streptococcus pnemoniae, Shigella flexneri, Candida albicans, Mycobacterium tuberculosis, and Chlamydia. The first three chapters are of wide interest as they cover fundamental concerns in new vaccine developments. The first one presents the immune system and how carbohydrate antigens are processed before protective antibodies are produced. It also illustrates antigen presentation in the context of major histocompatibility complexes (MHCs). The second chapter describes regulatory issues when carbohydrate vaccines are involved while the third one discuss several techniques used in conjugation chemistry and the implication of certain chemical linkages that may induce unexpected anti-linker antibodies. This section will be particularly appealing for those involved in drug-conjugate design, pro-drug developments, and drug vectorization. The book concludes with one chapter that illustrates the principle through which peptide antigens can functionally mimic carbohydrate epitopes, thus, unraveling the potential for peptide surrogates as replacement for complex carbohydrate structures. This book is unique in that it covers all aspects related to carbohydrate vaccines including the success story with the first semi-synthetic bacterial polysaccharide vaccine against Heamophilus influenza type b responsible for pneumonia and meningitis, liable for more than 600,000 infant deaths worldwide in developing countries. The book also presents regulatory issues and will thus be vital for government agencies approving candidate vaccines. It widely covers synthetic methodologies for the attachment of carbohydrate antigens to peptides and immunogenic protein carriers. Vaccines against bacterial antigens, cancer, and parasites are also discussed by worldwide experts in this field in details. No other book contains such a wide panel of different expertise. It will also be useful to students and researchers involved with the immunology of forreings antigens and how the under appreciated carbohydrate antigens are processed by the immune system.

Download or read book Protein Ligand Interactions written by Hans-Joachim Böhm and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lock-and-key principle formulated by Emil Fischer as early as the end of the 19th century has still not lost any of its significance for the life sciences. The basic aspects of ligand-protein interaction may be summarized under the term 'molecular recognition' and concern the specificity as well as stability of ligand binding. Molecular recognition is thus a central topic in the development of active substances, since stability and specificity determine whether a substance can be used as a drug. Nowadays, computer-aided prediction and intelligent molecular design make a large contribution to the constant search for, e. g., improved enzyme inhibitors, and new concepts such as that of pharmacophores are being developed. An up-to-date presentation of an eternally young topic, this book is an indispensable information source for chemists, biochemists and pharmacologists dealing with the binding of ligands to proteins.

Download or read book Diarrhea and Malnutrition written by Lincoln Chen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several reasons why a consolidation of recent advances in our understanding of the interaction of diarrhea and malnutrition is indi cated and timely. It is now widely recognized that diarrhea is a major cause of morbidity and mortality among children of poor countries. Due to recent advances in laboratory and field diagnostic techniques, many of the previously unrecognized etiologic agents responsible for diarrhea have been identified, thereby providing new scientific knowledge for rational control strategies. Increasingly these advances suggest that the morbidity burden of diarrhea may be of equal, if not greater, public health consequence than mortality. Diarrhea only rarely causes disease severe enough to require institutionalized medical care. The vast major ity of diseases are of mild or moderate severity, and because of high prev alence, diarrhea imposes an enormous morbidity burden and exerts a sig nificant negative impact on child growth and development. Moreover, the effects of successive episodes of diarrhea are likely to be cumulative. In contrast to several other childhood infections, the treatment of the diarrheal diseases is feasible because it uses simple, effective, and low cost medical technologies. Within the context of these developments, there has been a major resurgence of international interest in, and commitment to, the control of the diarrheal diseases. The World Health Organization recently has launched a global program for the control of diarrhea, and simulta neously, an independent international research center on diarrhea has been established in Bangladesh.
Download or read book Carbohydrate Based Interactions at the Molecular and the Cellular Level written by Kieran L. Hudson and published by Springer. This book was released on 2018-05-28 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a clearly written and highly accessible account of two different aspects of carbohydrate chemistry. Carbohydrates are an essential component of life and have many important biological functions, but the details of how carbohydrates interact with other biomolecules to mediate biological signalling remain unclear. Firstly, this thesis details innovative methods to mine protein structural data to uncover new features of carbohydrate-based interactions. It also explains these findings using physical chemistry, specifically CH–pi interactions associated with the properties of the interacting partners. Carbohydrates are also critical for tissue growth and development, yet are underexploited in the materials science that underpins much of regenerative medicine. As such, the second part of this thesis describes a diverse array of techniques ranging from synthetic chemistry and enzymatic synthesis to prepare a wide variety of carbohydrates, and materials chemistry to prepare glycosylated hydrogels, to cell biology to determine the effects on cellular development for tissue engineering applications.

Download or read book Anticarbohydrate Antibodies written by Paul Kosma and published by Springer Science & Business Media. This book was released on 2011-11-27 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many pathogens and aberrant malignant cells express unique carbohydrates on their surface representing attractive targets for vaccine design. Considerable progress has recently been made in the identification of novel carbohydrate based vaccines and a large number has reached clinical phase studies. The success of several licensed carbohydrate based vaccines against bacterial pathogens such as Haemophilus influenzae type b, Neisseria meningitidis or Streptococcus pneumoniae demonstrates their great potential. However, the study of anti-carbohydrate antibodies is technically challenging and partly because of low affinities and promiscuous specificity they have not been medically exploited to full potential. The study of antibody specificities and identification of protective carbohydrate epitopes lies at the heart of successful vaccine design. In addition to therapy, antibodies in general serve as diagnostic tools in medical and scientific laboratories. In this setting high affinity and exquisite specificity are important factors for their successful use. “Anticarbohydrate Antibodies – from molecular basis to clinical application” compiles current knowledge on the immunological recognition of carbohydrates by the adaptive immune system from a molecular perspective providing fundamental insight needed for advancing clinically relevant diagnostics and therapeutic applications. Based on significant progress in the fields of glycoimmunology and structural biology in recent years, the book comprehensively reviews the state-of-the-art in defining the key elements of carbohydrate recognition by antibodies, the molecular mimicry of carbohydrate epitopes as well as the molecular features leading to specific and relaxed binding modes. Backed-up by a combination of modern technologies to elucidate structural details of carbohydrate-antibody interactions, biomedically important carbohydrate antigens from viral, bacterial, parasite, insect and tumor cells have been analyzed in in-depth reviews written by well-known experts in the field. Fundamental knowledge of these molecular mechanisms eventually provides a rational basis to improve efficacy of carbohydrate-based vaccines and to further refine diagnostic tools in detection of pathogens and malignant cells.
