A fully automated high-resolution in vivo screening platform for zebrafish was implemented and used to identify novel compounds that regulate oligodendrocyte lineage progression.
Heparan sulfate synthesis by mature oligodendrocytes creates a protective and permissive environment controling microglia and oligodendrocyte progenitors reactivation during remyelination.
Electrically active axons in white matter stimulate their own myelination by releasing glutamate, which signals through AMPA-type glutamate receptors on nearby oligodendrocyte precursors and newly-differentiating oligodendrocytes, enhancing their survival and hence their ability to myelinate.
Regeneration of oligodendrocytes in the cerebral cortex results in reorganization of the pattern of myelination, potentially impacting information processing within cortical networks in diseases such as multiple sclerosis.
In the peripheral nervous system, the large GTPase dynamin 2 is required for Schwann cell survival, developmental radial sorting of axons, myelination, and myelin maintenance.
Production of remyelinating subventricular zone oligodendrocyte progenitors is stimulated by transient abrogation of thyroid hormone signalling in the adult neural stem cell niche.
Although central nervous system (CNS) regeneration has been considered to be controlled by CNS microenvironment, CNS injury causes leading to leakage of circulating factors into CNS, which promotes CNS regeneration.
Gab1 is a key downstream effector of PDGF signaling and essential to oligodendrocyte differentiation by linking PDGF signaling with GSK3β/β-catenin module.
Mild myelin disruption leads to early axonal pathology, a novel pathological response in neural stem cells, regionally increased oligodendrocytes and altered behavior.
