Myelinated Fibres

Previous studies by a number of workers have shown that the axon membrane in normal mature myelinated fibres is highly differentiated, with the nodal axolemma exhibiting characteristics different to those of the internodal axolemma. However, the development of this axolemmal heterogeneity has not been previously explored. In the present study we used cytochemical methods to examine the development of nodal axolemma during the differentiation of myelinated fibres in rat spinal roots. The staining properties characteristic of normal nodal membrane appear in the axon, at gaps between Schwann cells, before the develop­ment of mature compact myelin or well defined paranodal axon-Schwann cell specializations close to the region of nodal axolemmal differentiation. These results are consistent with the hypothesis that the axon membrane differentiates into nodal and internodal regions before, or early in the process of, myelination, and suggest that the differentiation of the axon membrane may provide a signal demarcating the region to be covered by the myelin-forming cell.

The neuregulin1/ErbB system plays an important role in Schwann cell behavior both in normal and pathological conditions. Upon investigation of the expression of the neuregulin1/ErbB systemin vitro, we explored the possibility to manipulate the system in order to increase the migration of Schwann cells, that play a fundamental role in the peripheral nerve regeneration. Comparison of primary cells and stable cell lines shows that both primary olfactory bulb ensheathing cells and a corresponding cell line express ErbB1-ErbB2 and neuregulin1, and that both primary Schwann cells and a corresponding cell line express ErbB2-ErbB3, while only primary Schwann cells express neuregulin1. To interfere with the neuregulin1/ErbB system, the soluble extracellular domain of the neuregulin1 receptor ErbB4 (ecto-ErbB4) was expressedin vitroin the neuregulin1 expressing cell line, and an unexpected increase in cell motility was observed.In vitroexperiments suggest that the back signaling mediated by the transmembrane neuregulin1 plays a role in the migratory activity induced by ecto-ErbB4. These results indicate that ecto-ErbB4 could be usedin vivoas a tool to manipulate the neuregulin1/ErbB system.

Stimulation Of

Functional characterization of muscarinic cholinergic receptors in myelinating glial cells has been well described both in central and peripheral nervous system. Rat Schwann cells (SCs) express different muscarinic receptor subtypes with the prevalence of the M2 subtype. The selective stimulation of this receptor subtype inhibits SC proliferation, improving their differentiation towards myelinating phenotype. In this work, we describe for the first time that human SCs are cholinoceptive as they express several muscarinic receptor subtypes and, as for rat SCs, M2 receptor is one of the most abundant. Human SCs, isolated from adult nerves, were cultured in vitro and stimulated with M2 muscarinic agonist arecaidine propargyl ester (APE). Similarly to that observed in rat, M2 receptor activation causes a decreased cell proliferation and promotes SC differentiation as suggested by increased Egr2 expression with an improved spindle-like shape cell morphology. Conversely, the non-selective stimulation of muscarinic receptors appears to promote cell proliferation with a reduction of SC average cell diameter. The data obtained demonstrate that human SCs are cholinoceptive and that human cultured SCs may represent an interesting tool to understand their physiology and increase the knowledge on how the cholinergic stimulation may contribute to address human SC development in normal and pathological conditions.
