The autoimmune vulnerability of the node of Ranvier
The nodes of Ranvier (NoR) are essential domains for nerve conduction and their disruption plays a key role in the pathophysiology of immune-mediated neuropathies. Our understanding of the specialized nodal regions and the immune mechanisms that affect them is growing and has led to the update of peripheral neuropathy classification to include the autoimmune nodopathies, defined by the site of the autoimmune attack. Autoantibodies directed against molecules of the nodal region (as neurofascin-140/186, neurofascin-155, contactin-1, contactin-associated protein 1, contactin-associated protein 2, gangliosides, LGI4, or myelin-associated glycoprotein), macrophage-induced paranodal demyelination, and phenotypic changes of the nodal domains of Schwann cells have been identified as key mechanisms in the pathogenesis of the autoimmune neuropathies. This review explores the current knowledge of the autoimmune vulnerability of the NoR, including the underlying mechanisms leading to dysfunction in the diverse autoimmune disorders.
期刊介绍:
The Journal of the Peripheral Nervous System is the official journal of the Peripheral Nerve Society. Founded in 1996, it is the scientific journal of choice for clinicians, clinical scientists and basic neuroscientists interested in all aspects of biology and clinical research of peripheral nervous system disorders.
The Journal of the Peripheral Nervous System is a peer-reviewed journal that publishes high quality articles on cell and molecular biology, genomics, neuropathic pain, clinical research, trials, and unique case reports on inherited and acquired peripheral neuropathies.
Original articles are organized according to the topic in one of four specific areas: Mechanisms of Disease, Genetics, Clinical Research, and Clinical Trials.
The journal also publishes regular review papers on hot topics and Special Issues on basic, clinical, or assembled research in the field of peripheral nervous system disorders. Authors interested in contributing a review-type article or a Special Issue should contact the Editorial Office to discuss the scope of the proposed article with the Editor-in-Chief.
