Glycoconjugates and neuroimmunological diseases.
Autor(es): Willison Hugh J.
Resumo: A wide range of neuroimmunological diseases affect the central and peripheral nervous systems. These disorders are caused by autoimmune attack directed against structurally and functionally diverse nervous system antigens. One such category comprises peripheral nervous system (PNS) diseases, termed peripheral neuropathies, in which the target antigens for autoantibody-directed nerve injury are glycan structures borne by glycoproteins and glycolipids, particularly gangliosides that are concentrated in peripheral nerve. The archetypal PNS disorder is the acute paralytic disease, Guillain-Barré syndrome (GBS) in which autoantibodies against glycolipids arise in the context of acute infections that precede the clinical onset, notably Campylobacter jejuni enteritis. In addition, several chronic autoimmune neuropathies are associated with IgM antibodies directed against nerve glycans including sulphated glucuronic acid epitopes present on myelin-associated glycoprotein and sulphated glucuronyl paragloboside, a range of disialylated gangliosides including GD1b and GD3, and GM1 ganglioside. This chapter describes the immunological, pathological and clinical features of these disorders in the context of our broader knowledge of the glycobiology underpinning this neuroimmunological field.
