Myelination dictates axonal viscoelasticity
WebMyelination is a complex and orderly process during brain development that is essential for normal motor, cognitive and sensory functions. Cellular and molecular interactions between myelin-forming oligodendrocytes and axons are required for normal myelination in the developing brain. Web19 nov. 2024 · Here, we report that segmental myelination along neocortical interneuron axons is strongly predicted by the joint combination of interbranch distance and local axon caliber. Enlargement of PV+ interneurons increased axonal myelination, while reduced cell size led to decreased myelination.

Web19 nov. 2024 · To examine the relationship between the axonal morphology of PV+ interneurons and their myelination, we targeted fluorescent PV+ interneurons in the adult medial prefrontal cortex (mPFC) of Pvalb::cre (Hippenmeyer et al., 2005),Ai14 (Madisen et al., 2012) mice for whole-cell patch-clamp recording and biocytin filling (n = 8 cells; … Web19 sep. 2024 · In diseases such as multiple sclerosis (MS), inflammation can injure the myelin sheath that surrounds axons, a process known as demyelination. The spontaneous regeneration of myelin, called remyelination, is associated with restoration of function and prevention of axonal degeneration.
Web5 okt. 2024 · Myelination of axonal pathways has long been recognized as necessary for enhancing action potential conduction within the central nervous system and thus essential for healthy brain function. However, plastic changes in myelin during adulthood have only recently started being widely reported. WebMyelination dictates axonal viscoelasticity Published in: European Journal of Neuroscience, March 2024 DOI: 10.1111/ejn.15954: Authors: Ya‐Chen Chuang, Ace …
WebIn the peripheral nervous system (PNS), myelinated axon bundles constitute peripheral nerves, such as the sciatic nerve and the sural nerve, which link the CNS to peripheral targets. The optic nerve, being a CNS white matter tract, is erroneously named. Web14 okt. 2024 · Myelin is the lipidic insulating structure enwrapping axons and allowing fast saltatory nerve conduction. In the central nervous system, myelin sheath is the result of the complex packaging of multilamellar extensions of oligodendrocyte (OL) membranes. Before reaching myelinating capabilities, OLs undergo a very precise program of differentiation …
Web6 mrt. 2024 · Collectively, our findings indicate a direct link between myelination, axonal orientation, and viscoelasticity, providing important insights about the mechanical environment in the pediatric brain, with direct implications for our understanding of …
Web8 mrt. 2024 · The myelination of axons by oligodendrocytes is a highly complex cell-to-cell interaction. Oligodendrocytes and axons have a reciprocal signaling relationship in which oligodendrocytes receive cues from axons that direct their myelination, and oligodendrocytes subsequently shape axonal structure and conduction. … glass bottle light fixtureWebA stabilizing effect of mature myelin on the neuronal cytoskeleton is mediated in part by the myelin associated glycoprotein (MAG) which requires two axonal receptor families: … glass bottle making companiesWeb22 apr. 2016 · Development of the embryonic cortical cell co-culture assay.
