Myelination and mTOR
Myelinating cells surround axons to accelerate the propagation of action potentials, to support axonal health, and to refine neural circuits. Myelination is metabolically demanding and, consistent with this notion, mTORC1-a signaling hub coordinating cell metabolism-has been implicated as a key signal for myelination. Here, we will discuss metabolic aspects of myelination, illustrate the main m...
متن کاملAkt/mTOR signalling in myelination.
Akt signalling has emerged as one of the major pathways involved in myelination, implicated in the regulation of several steps during the development of myelinating Schwann cells and oligodendrocytes. One of the main pathways intimately linked with Akt is mTOR [mammalian (or mechanistic) target of rapamycin] signalling. Recent evidence suggests that many processes attributed to the Akt pathway ...
متن کاملArrest of myelination and reduced axon growth when Schwann cells lack mTOR.
In developing peripheral nerves, differentiating Schwann cells sort individual axons from bundles and ensheath them to generate multiple layers of myelin. In recent years, there has been an increased understanding of the extracellular and intracellular factors that initiate and stimulate Schwann cell myelination, together with a growing appreciation of some of the signaling pathways involved. H...
متن کاملMyelination
Feltri et al. (2001)(this issue) succeed in disrupting beta 1 integrin specifically in Schwann cells, and in so doing, demonstrate that it is required for normal myelination. Their results reveal that signaling by an extracellular matrix receptor plays a key role in the differentiation of myelinating Schwann cells.
متن کاملMyelination
Myelin is a key evolutionary acquisition that underlay the development of the large, complex nervous systems of all hinged-jaw vertebrates. By promoting rapid, efficient nerve conduction, myelination also made possible the development of the large body size of these vertebrates. In addition to increasing the speed of nerve conduction, myelination has emerged as a source of plasticity in neural ...
