WebThe cross (transverse) view allows comparison of the numbers and densities of myelinated nerve fibers (large-caliber, pale blue axons bounded by thick, dark myelin sheaths) and possibly unmyelinated fibers (small-caliber axons with minimal myelin [often found in small clusters]), although such fine discrimination is only possible in specially prepared nerves … WebIn vitro myelination assays were done to measure the myelination capacity of oligodendrocytes treated with sildenafil. ... EZH2 suppression-dependent effects on morphology and myelin genes could be reversed by concomitant suppression of p57kip2, indicating that p57kip2 is a downstream effector of EZH2.
Regulation of myelin structure and conduction velocity by …
WebThe adhesion G protein-coupled receptor (GPCR) Gpr126 is essential for Schwann cells to initiate myelination, but previous studies have not addressed the role of Gpr126 signaling in myelin maturation and maintenance. Through analysis of Gpr126 in zebrafish, we define two distinct mechanisms controlling the initiation and maturation of myelin.

WebMyelTracer readily recognizes well-developed myelin sheaths in micrographs of both central and peripheral nerves and axon tracts. In contrast to the relatively thick and compact myelin in these tissues, myelin in remyelinating tissues after injury is characterized by a thinner morphology (Franklin and ffrench-Constant, 2008; Duncan et al., 2024). WebNov 13, 2024 · Previously, it was unknown how the myelin sheath could be thinned and the functions of perinodal astrocytes were not well understood. These findings describe a … WebOligodendrocytes are specialised glial cells that myelinate CNS axons. Myelinated axons are bundled together into white matter tracts that interconnect grey matter areas of the brain and are essential for rapid, integrated neuronal communication and cognitive function. Life-long generation of oligodendrocytes is required for myelination of new neuronal connections … debourgh name
