Carbohydrate Based Vaccines

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.

The fundamental science and the latest developments in carbohydrate-based vaccines The relatively new field of glycoimmunology has emerged from the marriage of glycobiology and immunology, in recognition of the important role carbohydrates play as antigenic determinants. Carbohydrate-Based Vaccines and Immunotherapies comprehensively reviews the state of this exciting field, offering a single source for both the fundamental science and the latest developments. With contributions by leading experts, this resource covers the design, synthesis, evaluation, and applications of various carbohydrate-based vaccines, including polysaccharides, neoglycoproteins, and neoglycolipids. The text approaches vaccine design from a chemical and molecular focus, staying in line with current advances. Key topics covered by Carbohydrate-Based Vaccines and Immunotherapies include: Recent developments towards clinically useful vaccines against bacteria, viruses, parasites, and fungi Using adjuvants to improve immunogenicity and/or immunological properties of vaccines Choosing and designing proper adjuvants for specific targets Abnormal carbohydrates expressed by tumors Carbohydrate-based therapeutic cancer vaccines or cancer immunotherapy Clinical trials results for synthetic cancer vaccines Glycoengineering of cell surface carborhydrates and its anticancer applications Using cell surface carbohydrates for disease diagnosis A single, convenient source of state-of-the-art information from leading authorities in the field, Carbohydrate-Based Vaccines and Immunotherapies is an essential reference for organic chemists and biochemists, academic researchers, and other students and professionals involved in vaccine design.

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.

The past three decades have witnessed the development and regulatory approval of glycoconjugate vaccines against several medically important bacterial pathogens, including Haemophilus influenzae type b, Streptococcus pneumoniae, Neisseria meningitides, and Salmonella typhi. Immunologic protection against these and many other bacterial diseases is mediated through opsonophagocytic antibodies directed against the surface carbohydrates that define the bacterial serogroup or serotype and serve as virulence factors. These vaccines are composed of bacterial capsular polysaccharides chemically conjugated to immunogenic carrier proteins. Given that the diseases caused by these bacterial pathogens are most pronounced in infants and young children, the development of the glycoconjugate vaccine technology has had a considerable impact on public health. Many of the chapters in this volume were assembled as a follow-up from a symposium entitled "Carbohydrate-Based Vaccines and Adjuvants" which took place at the 254th American Chemical Society National Meeting held in Washington, DC (August 2017). The symposium was sponsored by Pfizer and the Carbohydrate (CARB) and Biotechnology (BIOT) divisions. This book, therefore, reflects the importance of this field toward design, development, manufacture and licensure of the complex carbohydrate-based (glycoconjugate) vaccines. The book has been organized into thirteen chapters, which cover a comprehensive landscape including the clinical history, design, development, chemistry, manufacturing and control (CMC) aspects, pre-clinical assays, adjuvants and the various approaches used to develop carbohydrate-based vaccines.

This volume summarizes current cutting-edge methods related to carbohydrate-based vaccines, from the identification of a suitable carbohydrate antigen via the preparation of glycoconjugate vaccines to the characterization of vaccine candidates for their use in pre-clinical and clinical studies. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Carbohydrate-Based Vaccines: Methods and Protocols aims to be a valuable manual that will facilitate research in the field of carbohydrate-based vaccines.

Developed from a symposium at the Fourth Chemical Congress of North America (202nd National Meeting of the ACS) in New York City, August 1991, chapter-papers present research on topics including how proteins recognize and bind oligosaccharides, synthesis and immunological properties of glycopeptide T-cell determinants, Vibrio cholerae polysaccharide studies, and purification of oligosaccharide antigens by weak affinity chromatography.

This book contains original papers and reviews on carbohydrate research in medicine, authored by participants of the 29th International Carbohydrate Symposium, where this topic had a special emphasis. The focus on biological events involving carbohydrates and glycoconjugates has delivered reliable approaches for disease treatment and diagnosis. Research on carbohydrate-based compounds for therapeutic applications is illustrated in various contributions, namely those covering the development of novel agents against Alzheimer’s disease, e.g. the neuroprotective C-glucosylated flavones and the isonucleoside-based cholinesterase inhibitors. New imino sugar glucosidase inhibitors are also disclosed, a class of compounds with potential for diabetes, Gaucher disease or cancer treatment. Also the development of a useful synthetic method towards multivalent glycoclusters of biomedical interest is here highlighted. The relevance of glycomimetics in drug discovery and the progress on carbohydrates in early diagnosis and cancer treatment are reviewed. Noteworthy is the chitosan-based delivery system for drug oral administration, a new biomaterial-based approach to improve bioavailability. Another study on the conformation of Streptococcus capsular polysaccharide backbones by molecular modelling provides useful information for bacterial immunotherapeutic approaches. All original contributions and reviews clearly demonstrate the potential of glycosciences for innovation in medicinal (glyco)chemistry and pharmaceutical research.
