O Glycosylation In Health And Disease

Glycobiology is an emerging field of studying glycans (sugars) and glycoconjugates that are essentially involved in almost all biological processes, from fine-tuning glycoprotein function to protein-protein interactions, signaling, immune response, host-pathogen interactions, etc. However, due to structural complexity of glycans and analytical challenges this exciting field was lagging behind other areas of biology. With technological advancements growing number of glycans’ functions are being discovered and the study of glycans is becoming a cutting-edge discipline in basic and clinical research. Despite recent developments in glycobiology field, many aspects of glycosylation process still remain unknown, both in a healthy human organism and in pathological states. Human glycome is dynamic and changes with physiological triggers, immune challenges and disease. Atypical glycosylation is consequently a subject of disease biomarker research, and a target for therapeutic interventions. On the other hand, properties of glycosylated biotherapeutics are predominantly determined by their glycans. The Role of Glycosylation in Health and Disease provides a comprehensive overview of types and functions of glycans in a healthy human organism as well as their role in pathophysiology of different diseases and efficiency of glycosylated biotherapeutics. Written by the experts in the field, this book aims to bring glycobiology field closer to students, researchers in life sciences and professionals in biopharmaceutical industry.

This book summarizes recent advances in antibody glycosylation research. Covering major topics relevant for immunoglobulin glycosylation - analytical methods, biosynthesis and regulation, modulation of effector functions - it provides new perspectives for research and development in the field of therapeutic antibodies, biomarkers, vaccinations, and immunotherapy. Glycans attached to both variable and constant regions of antibodies are known to affect the antibody conformation, stability, and effector functions. Although it focuses on immunoglobulin G (IgG), the most explored antibody in this context, and unravels the natural phenomena resulting from the mixture of IgG glycovariants present in the human body, the book also discusses other classes of human immunoglobulins, as well as immunoglobulins produced in other species and production systems. Further, it reviews the glycoanalytical methods applied to antibodies and addresses a range of less commonly explored topics, such as automatization and bioinformatics aspects of high-throughput antibody glycosylation analysis. Lastly, the book highlights application areas ranging from the ones already benefitting from antibody glycoengineering (such as monoclonal antibody production), to those still in the research stages (such as exploration of antibody glycosylation as a clinical or biological age biomarker), and the potential use of antibody glycosylation in the optimization of vaccine production and immunization protocols. Summarizing the current knowledge on the broad topic of antibody glycosylation and its therapeutic and biomarker potential, this book will appeal to a wide biomedical readership in academia and industry alike.

Sugar chains (glycans) are often attached to proteins and lipids and have multiple roles in the organization and function of all organisms. "Essentials of Glycobiology" describes their biogenesis and function and offers a useful gateway to the understanding of glycans.

What is Glycosylation? The Role Play of Glycosylation in Health & Disease. An Overview. Glycosylation is an enzymatic process that attaches carbohydrate or a glycan to proteins, or other organic molecules such as lipids. Glycosylation is a dynamic process that depends on the local milieu of enzymes, sugar precursors and organelle structures as well as the cell types involved and cellular signals. Researchers can now routinely assess how the secreted and cell-surface glycomes reflect overall cellular status in health and disease. In fact, changes in glycosylation can modulate inflammatory responses, enable viral immune escape, promote cancer cell metastasis, or regulate apoptosis; the composition of the glycome also affects kidney function in health and disease. New insights into the structure and function of the glycome can now be applied to therapy development and could improve our ability to fine-tune immunological responses and inflammation, optimize the performance of therapeutic antibodies and boost immune responses to cancer. These examples illustrate the potential of the emerging field of ‘GLYCOMEDICINE’. It is strived in this Booklet to review how glycosylation patterns are altered in multiple human diseases, including Congenital Disorders of Glycosylation (CDGs), Autoimmune, Infectious & Chronic Inflammatory Diseases and Cancer, providing specific examples of how an improved understanding of abnormal glycosylation in various diseases might offer new diagnostic options and/or targets for glycan-mediated therapeutic interventions.

A new focus on glycoscience, a field that explores the structures and functions of sugars, promises great advances in areas as diverse as medicine, energy generation, and materials science, this report finds. Glycans--also known as carbohydrates, saccharides, or simply as sugars--play central roles in many biological processes and have properties useful in an array of applications. However, glycans have received little attention from the research community due to a lack of tools to probe their often complex structures and properties. Transforming Glycoscience: A Roadmap for the Future presents a roadmap for transforming glycoscience from a field dominated by specialists to a widely studied and integrated discipline, which could lead to a more complete understanding of glycans and help solve key challenges in diverse fields.

Sialic Acids and Sialoglycoconjugates in the Biology of Life, Health and Disease enables the reader to understand the role of sialylation as a post translational modification. The book provides insights on the latest knowledge in the field of sialoglycobiology. Sialic acids as terminal residues of oligosaccharide chains play crucial roles in several cellular recognition events. Synthesized post translationally, they play an important role in recognition, signaling, immunological response and cell-cell interaction. Improper sialylations have been associated with several diseases including cancer. In the post genomics and proteomics era, sialoglybiology has become more and more important in deciphering health and disease conditions. Discusses the sialic acids and their role in different diseases (other than cancer) Provides an understanding of sialylations as post translational modifications (PTM) Demonstrates the impact sialylation has on infectious diseases, the autoimmune system and health Gives insights on the importance of sialic acid biology through animal models

This volume examines all facets of the complex biology of Immunoglobulin E (IgE) antibodies, which play an essential role in the pathophysiology of allergic diseases and immunity to parasites. It highlights the unique mechanisms involved in the regulation of IgE production at both the molecular and cellular level. Furthermore, it discusses in detail novel findings on how the affinity, specificity and cross-reactivity of IgE can fine-tune mast cell responses to allergens. The book also explores the beneficial roles of IgE antibodies in immunity to helminthes and protection against tumors, and how the properties of IgE-mediated immunity are employed in the development of IgE therapeutic antibodies. All chapters were written by respected experts in their fields and will appeal to scientists and clinicians alike.

Along with nucleic acids, proteins, and lipids, carbohydrates stand as one of four main components of cellular architecture. However, glycobiology (or carbohydrate bioscience) is little understood by non-experts, partly because carbohydrates are a complex, diverse class of molecules structurally and functionally. In recent years, advances in computational analytics (glycomics) have allowed us to better interpret and realize the importance of glycobiology in human health and disease, and glycans and their associated processes have been shown to play a significant role across a variety of disease types. As the biomedical sciences continue to adopt multi-omic and precision medicine approaches, a greater understanding of glycobiology is essential for maintaining healthy physiology and advancing disease treatment.Translational Glycobiology in Human Health and Disease offers a deep examination of glycobiology for experts and non-experts alike in areas ranging from the role of glycobiology in chronic and infectious diseases to advances in technologies for higher throughput analysis and diagnosis.
