It also discusses the structure, composition, and isolation of surface membranes; and lectins – its immunological aspects and its use in the study of mammalian glycoprotein. The book is recommended for molecular biologists, organic chemists, and biochemists who would like to know more about glycolipids and glycoproteins and their applications.




Carbohydrate-based Vaccines


Book Description

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.

Ultracytochemistry of Intracellular Membrane Glycoconjugates


Book Description

This investigation is concerned with the ultracytochemistry of glycoconjugates - i. e., the carbohydrate moieties of glycoproteins and glycolipids - attached to intracellular post-Golgi membranes (membranes of lysosomes, peroxisomes, secretory granules of exocrine and endocrine gland cells). In addition mitochon dria have been studied. There are at present very few cytochemical studies, none of them systematic, on intracellular membrane-bound glycoconjugates. So far it has only been re ported that phosphotungstic acid (PTA) at low pH (pH




Glycoconjugate Research


Book Description

Glycoconjugate Research, Volume II contains the proceedings of the Fourth International Symposium on Glycoconjugates held in Woods Hole, Massachusetts in 1977. The papers explore the biosynthesis and regulation of glycoconjugates, particularly those of cell membranes, and glycolipid storage diseases. This volume is comprised of 95 chapters divided into three sections. After reviewing the regulatory mechanisms underlying glycoprotein synthesis, it turns to enzymic modifications of sialic acids in the course of glycoconjugate biosynthesis. The following chapters focus on the biosynthesis and characterization of lipid-linked sugars in the outer membrane of liver mitochondria; effect of bacitracin on the biosynthesis of dolichol derivatives in calf pancreas microsomes; secretion of proteoglycans by chondrocytes; and heterogeneity of arterial proteoglycans. The biosynthesis of elastin by chondroblasts in monolayer cultures is also considered, along with the phosphorylation of proteoglycans in human articular cartilage. The final chapter describes a double-antibody radioimmunoassay for soluble and cell-surface blood group Ii antigens. This book will be a useful resource for biochemists.

Enzymes of Lipid Metabolism II


Book Description

This book presents the proceedings of the 2nd meeting on "Enzymes of Lipid Metabolism" which took place in Strasbourg in October, 1985. It is a sequel to the first conference bearing this title which took place, also in the vicinity of Strasbourg, in March, 1977. In either case the meetings were coorganized by L. Freysz of Strasbourg, France and S. Gatt of Jerusalem, Israel. The present meeting was set up as a joint NATO Advanced Research Workshop and CNRS-INSERM International Symposium. The conference was guided by two principles, namely, that science has no bounderies, neither has the study of lipid metabolism. Participants came from Europe, the USA, Israel and Japan and represented areas of research in lipid metabolism involving fatty acid s, cholesterylesters, glycero-and sphingolipids. The experimental approaches utilized purified enzymes, artificial and biological membranes, as well as a variety of cells, primary or cultured lines. A session was also devoted to modification of lipid enzymes and metabolism resulting from inherited, inborn defects such as the lipid storage diseases which are caused by genetic modification of degradative enzymes of lipid metabolism. A second type of disease stemming from a defect in a cell organnel (ie, the peroxisome) was also discussed. The eight and one and a half years which elapsed since the previous meeting, highlighted the changing emphasis of research in. lipid metabolism.
