Overview
From WUSTL NeuromuscularDemyelinated axons Macrophage-mediated myelin stripping 1 Often immune mediated Guillain-Barré CIDP Initial locations: Commonly either At nodes of Ranvier At paranodes Along myelin internode Animal model: Experimental allergic neuritis (EAN) Macrophage Variant: Axon pathology, Non-demyelinating Acute Motor Axonal Neuropathy: Macrophages invade axons Myelinopathies with Nodal/Paranodal antibodies Macrophages: Not common Onion bulbs: Uncommon Axons with disroportionally thick myelin sheaths Myelin Layer Periodicity: Pathology Uncompacted myelin: Cytoplasmic aspects of Schwann cell membrane not a
