Summary:
The body’s ability to perform simple tasks like flex muscles or feel heat, cold and pain depends, in large part, on myelin, an insulating layer of fats and proteins that speeds the propagation of nerve cell signals. Now, scientists have identified a gene in mice that controls whether certain cells in the peripheral nervous system can make myelin. Called Gpr126, the gene encodes a cellular receptor that could play a role in diseases affecting peripheral nerves, says Kelly R. Monk, PhD, assistant professor of developmental biology at Washington University School of Medicine in St. Louis. The work is currently available online and will be published in the July 1 issue of the journal Development.
