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.

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.

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.

Structure of Antigens discusses a variety of topics dealing with the structural basis of antigenicity. Topics include the analytical methods used to elucidate the structure of antigens, the structure of antibodies, the principles underlying modern immunoassays and the measurement of antibody binding affinity, and physicochemical principles and methodological aspects. The book also considers major groups of antigens distinguished by their functional activity and biological role (e.g., drugs, autoantigens, snake toxins, allergens) or by their association with particular biological systems (e.g., antigens of microorganisms). Structure of Antigens will provide a current, useful, reference for researchers and graduate students in all fields of biological science who need an overview of antigenic specificity. VOLUME II

Tumor associated carbohydrate antigens (TACAs) are overexpressed on tumor cells, which renders them attractive targets for anti-cancer vaccines. To overcome the poor immunogenecity of TACAs, a polymer platform was designed for antigen presentation by taking advantage of the polymeric backbone to deliver TACA and helper T (Th) cell epitope on the same chain. The block copolymer was synthesized by cyanoxyl-mediated free radical polymerization followed by conjugation with a TACA Tn antigen and a mouse Th-cell peptide epitope derived from poliovirus (PV) to afford the vaccine construct. The glycopolymer vaccine elicited a robust immune response with significant titers of IgG antibodies and the antibodies generated recognized Tn antigens on tumor cell surface. For successful carbohydrate based anti-cancer vaccines, it is critical that B cells are activated to secret antibodies targeting TACAs. Despite the availability of many TACA based constructs, systematic understanding of the effects of structural features on anti-glycan antibody responses is lacking. In this study, a series of defined synthetic glycopolymers bearing a representative TACA, i.e., the Thomsen-nouveau (Tn) antigen, have been prepared to probe the induction of early B cell activation and antibody production via a T cell independent mechanism. Valency and density of the antigen in the polymers turned out to be critical. An average of greater than 6 Tn per chain was needed to induce antibody production. Glycopolymers with 40 antigens per chain and backbone molecular weight of 450 kDa gave the strongest stimulation to B cells in vitro, which correlated well with its in vivo activity. Deviations from the desired valency and density led to decreased antibody production or even antigen specific B cell non-responsiveness. These findings provide important insights on how to modulate anti-TACA immune responses facilitating the development of TACA based anti-cancer vaccines using glycopolymers.
