Precise Role

We propose a new hypothesis about the physical-chemical mechanisms of nerve conduction in myelinated nerves, tending to bridge the theoretical gap existing to date between the basic neuronal activity and its adaptation to myelination. All the considerations imply a simplification of the underlying theories, identifying a precise role for myelin. The ATP-supplying energetic role for myelin allows to overcome the theories that have not yet found a physical-chemical solid confirmation. A radical simplification of nerve conduction mechanism is envisaged: it can be supposed that this mechanism remains unaltered in the passage from the unmyelinated to the myelinated conditions.

Abstract The perineurium constitutes the basis for the regulation of endoneurial fluid homeostasis. In the work presented here, cytokeratin 18, as an immunohistochemical marker for epithelial cells, was used to identify the perineurium in the peripheral nerves of two species. Two organs, rich in peripheral nerves, were used; the tongue of the bull and the ductus deferens of the male goat. Special attention was paid to one of the the nerve sheath cells - the perineurial cells of myelinated nerves in the skeletal muscle of the tongue and in the smooth muscle in the wall of the ductus deferens. A positive reaction to cytokeratin 18 was found in the perineurial cells of the perineurial sheath in the nerves of various sizes. No difference in the reactivity was observed between the peripheral nerves of the tongue and that of the ductus deferens.

The development and maintenance of myelinated nerves in the PNS requires constant and reciprocal communication between Schwann cells and their associated axons. However, little is known about the nature of the cell-surface molecules that mediate axon–glial interactions at the onset of myelination and during maintenance of the myelin sheath in the adult. Based on the rationale that such molecules contain a signal sequence in order to be presented on the cell surface, we have employed a eukaryotic-based, signal-sequence-trap approach to identify novel secreted and membrane-bound molecules that are expressed in myelinating and non-myelinating Schwann cells. Using cDNA libraries derived from dbcAMP-stimulated primary Schwann cells and 3-day-old rat sciatic nerve mRNAs, we generated an extensive list of novel molecules expressed in myelinating nerves in the PNS. Many of the identified proteins are cell-adhesion molecules (CAMs) and extracellular matrix (ECM) components, most of which have not been described previously in Schwann cells. In addition, we have identified several signaling receptors, growth and differentiation factors, ecto-enzymes and proteins that are associated with the endoplasmic reticulum and the Golgi network. We further examined the expression of several of the novel molecules in Schwann cells in culture and in rat sciatic nerve by primer-specific, real-time PCR and in situ hybridization. Our results indicate that myelinating Schwann cells express a battery of novel CAMs that might mediate their interactions with the underlying axons.
