In the peripheral nervous system, Schwann cells (SCs) form myelin sheaths around axons during nerve development. Such myelination is compromised in a number of diseases. Hence, identification and understanding of the key pathways regulating SC development and myelinogenesis are essential for therapeutic progress. Here we uncover two separate roles of the cellular signaling node mTORC1 (mechanistic target of rapamycin complex 1) for regulating the development of SCs and subsequently the growth of myelin sheaths. Moreover, we demonstrate that defective SCs possess a remarkable plasticity to remyelinate axons via mTORC1. Thus, manipulating mTORC1 activity in diseased SCs could be therapeutically beneficial. https://www.leica-microsystems.com//science-lab/mtorc1-promotes-proliferation-of-immature-schwann-cells-and-myelin-growth-of-differentiated-schwann-cells/ Wed, 16 May 2018 22:00:00 +0000 https://www.leica-microsystems.com/15645 Confocal Microscopy Live-Cell Imaging Label-free in vivo Imaging of Myelinated Axons in Health and Disease with Spectral Confocal Reflectance Microscopy We report a new technique for high-resolution in vivo imaging of myelinated axons in the brain, spinal cord and peripheral nerve that requires no fluorescent labeling. This method, based on spectral confocal reflectance microscopy (SCoRe), uses a conventional laser scanning confocal system to generate images by merging the simultaneously reflected signals from multiple lasers of different wavelengths. https://www.leica-microsystems.com//science-lab/label-free-in-vivo-imaging-of-myelinated-axons-in-health-and-disease-with-spectral-confocal-reflectance-microscopy/ Fri, 01 Jul 2016 09:29:00 +0000
