WebThe recently determined structure of protein zero, P0, the most abundant peripheral nerve myelin protein, provides new insights into the molecular structure of myelin and potential disease mechanisms in hereditary peripheral neuropathies. Web2 apr. 2016 · Oligodendrocytes wrap neuronal axons to form myelin, an insulating sheath which is essential for nervous impulse conduction along axons. Axonal myelination is highly regulated by neuronal and astrocytic signals and the maintenance of myelin sheaths is a very complex process.
