Research Abstract:

The myelin sheath surrounding axons is an exquisite specialized membrane found in the vertebrate nervous system. Myelin is formed by glial cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The importance of myelin is underscored by diseases that compromise the integrity of myelinated axons, including multiple sclerosis and Charcot-Marie-Tooth disease. Despite its importance, however, relatively little is known about how the myelin sheath is formed and maintained. We are interested in the mechanisms that govern the development, maintenance, and regeneration of myelinated axons using both zebrafish and mouse models. We seek to uncover regulators of nervous system development, homeostasis, and repair.
