Myelinating Schwann Cell Polarity and Mechanically-Driven Myelin Sheath Elongation [PDF]
Myelin sheath geometry, encompassing myelin sheath thickness relative to internodal length, is critical to optimize nerve conduction velocity and these parameters are carefully adjusted by the myelinating cells in mammals.

Myelin sheath injury and repairment after subarachnoid hemorrhage [PDF]
Subarachnoid hemorrhage (SAH) can lead to damage to the myelin sheath in white matter. Through classification and analysis of relevant research results, the discussion in this paper provides a deeper understanding of the spatiotemporal change ...

Oligodendrocyte HCN2 Channels Regulate Myelin Sheath Length. [PDF]
Oligodendrocytes generate myelin sheaths vital for the formation, health, and function of the CNS. Myelin sheath length is a key property that determines axonal conduction velocity and is known to be variable across the CNS. Myelin sheath length can be modified by neuronal activity, suggesting that dynamic regulation of sheath length might contribute ...

Clinical concentration of sevoflurane had no short-term effect on the myelin sheath in prefrontal cortex of aged marmosets [PDF]
IntroductionThe fragile brain includes both the developing brain in childhood and the deteriorating brain in elderly. While the effects of general anesthesia on the myelin sheath of developing brain have been well-documented, limited research has ...

Oligodendrocyte calcium signaling promotes actin-dependent myelin sheath extension [PDF]
Myelin is essential for rapid nerve signaling and is increasingly found to play important roles in learning and in diverse diseases of the CNS. Morphological parameters of myelin such as sheath length are thought to precisely tune conduction velocity ...

A myelin sheath protein forming its lattice. [PDF]
The formation of a mature, multilayered myelin sheath requires the compaction of lipid bilayers, but the molecular mechanism by which these bilayers condense is an open question. In this issue, Ruskamo et al. find that peripheral myelin protein P2 forms an ordered three-dimensional lattice within model membranes using Escherichia coli polar lipid ...

Pain kept under wraps of myelin sheath. [PDF]
The myelin sheath serves both as insulator and metabolic powerhouse for large-diameter dorsal root ganglia (DRG) neurons—some of the longest cells in the body—transmitting sensory impulses from the periphery to the spinal cord. When myelin is damaged, bioactive fragments of myelin basic protein (MBP) are released, playing a pivotal role in pathological

Shielding effects of myelin sheath on axolemma depolarization under transverse electric field stimulation [PDF]
Axonal stimulation with electric currents is an effective method for controlling neural activity. An electric field parallel to the axon is widely accepted as the predominant component in the activation of an axon.

Role of Connexin-Based Gap Junction Channels in Communication of Myelin Sheath in Schwann Cells [PDF]
Peripheral nerves have the capacity to conduct action potentials along great distances and quickly recover following damage which is mainly due to Schwann cells (SCs), the most abundant glial cells of the peripheral nervous system (PNS).
