Peripheral nervous system plasmalogens regulate Schwann cell differentiation and myelination.
Rhizomelic chondrodysplasia punctata (RCDP) is a developmental disorder characterized by hypotonia, cataracts, abnormal ossification, impaired motor development, and intellectual disability. The underlying etiology of RCDP is a deficiency in the biosynthesis of ether phospholipids, of which plasmalogens are the most abundant form in nervous tissue and myelin; however, the role of plasmalogens i...
متن کاملSchwann cell spectrins modulate peripheral nerve myelination.
During peripheral nerve development, Schwann cells ensheathe axons and form myelin to enable rapid and efficient action potential propagation. Although myelination requires profound changes in Schwann cell shape, how neuron-glia interactions converge on the Schwann cell cytoskeleton to induce these changes is unknown. Here, we demonstrate that the submembranous cytoskeletal proteins αII and βII...

Laminin γ1 is critical for Schwann cell differentiation, axon myelination, and regeneration in the peripheral nerve
Laminins are heterotrimeric extracellular matrix proteins that regulate cell viability and function. Laminin-2, composed of alpha2, beta1, and gamma1 chains, is a major matrix component of the peripheral nervous system (PNS). To investigate the role of laminin in the PNS, we used the Cre-loxP system to disrupt the laminin gamma1 gene in Schwann cells. These mice have dramatically reduced expres...
متن کاملDe novo fatty acid synthesis by Schwann cells is essential for peripheral nervous system myelination
Myelination calls for a remarkable surge in cell metabolism to facilitate lipid and membrane production. Endogenous fatty acid (FA) synthesis represents a potentially critical process in myelinating glia. Using genetically modified mice, we show that Schwann cell (SC) intrinsic activity of the enzyme essential for de novo FA synthesis, fatty acid synthase (FASN), is crucial for precise lipid co...
