Abstract
Nerve conduction in myelinated axons is a fascinating subject due to the intricate structure and complex properties of the axon and its relation to the equally complex Schwann cells surrounding it. This chapter first deals with normal functional aspects of voltage-gated ion channels in the axon and Schwann cell membranes as well as their related proteins. Next, the pathophysiological alterations that are induced by experimental studies to mimic and study neuropathic disorders in humans are discussed. Finally, a link is made with human neuropathies associated with antibodies against gangliosides, and the putative mechanisms of axonal degeneration in demyelinating neuropathies are discussed. Although this chapter is relevant to understand symptoms in human neuropathies, the reader is referred to Franssen and Straver (Muscle Nerve 49:4–20, 2014) for a review of translational and clinical studies in human patients.
