Neurotransmitter-mediated regulation of CNS myelination: a review.
In addition to treatments aimed at preventing or limiting damage to myelin and oligodendrocytes, there is a crucial need for repair strategies in human demyelinating disorders. There is increasing evidence that besides growth factors, neurotransmitters can regulate different steps of the oligodendrogliogenesis. The present review on neurotransmitter receptor expression and function in the oligodendrocyte lineage emphasizes the concept that in this lineage cell proliferation and differentiation can be controlled through the modulation of the functional state of channel proteins and receptors, such as the delayed K+ rectifier, the AMPA/kainate, dopamine or muscarinic receptors, and, most likely, others yet to be found. We anticipate that a better understanding of the neurotransmitter-mediated neuronal oligodendroglial communication network opens prospects in the field of central nervous system (CNS) myelin repair, allowing the recruitment of the myelinating machinery that is known to remain present but quiescent in the CNS of multiple sclerosis patients.
