This book contains the Proceedings of the Sixth Jenner Glycobiology and Medicine Symposium, held 14-17 September, 2002, in Seillac, France. This book highlights the latest developments in glycoimmunology, including glycosylation-dependent bacterial and viral infections, lectin and proteoglycan-dependent interactions in leukocyte homing processes to lymphoid tissues and inflamed tissues, congenital defects in glycosylation of glycoproteins and glycolipids, and the role of carbohydrates in tumour development and neuropathology, including Creutzfeldt-Jakob disease.
