Microglia phagocytose myelin sheaths to modify developmental myelination [PDF]

open access: yesNature Neuroscience, 2020
During development, oligodendrocytes contact and wrap neuronal axons with myelin. Similarly to neurons and synapses, excess myelin sheaths are produced and selectively eliminated, but how elimination occurs is unknown. Microglia, the resident immune cells of the central nervous system, engulf surplus neurons and synapses. To determine whether microglia

Advanced Maternal Age Impairs Myelination in Offspring Rats

open access: yesFrontiers in Pediatrics, 2022
The effects of advanced maternal age (AMA) on the neurodevelopment of offspring are becoming increasingly important. Myelination is an important aspect of brain development; however, a limited number of studies have focused on the effects of AMA on ...

Microtubules, Myelin Sheaths, and Altered Behavior [PDF]

open access: yeseneuro, 2021
Mice are skttish creatures that innately hide from perceived threats by staying out of open areas, freezing to avoid predators, or hiding in dark spaces when an adverse stimulus is sensed. However, after inducing a global TPPP (tubulin polymerization promoting protein) gene knock-out (KO), which results in reduced myelin length and thickness (Fu et al.,

Mechanical Responses of a Single Myelin Layer: A Molecular Simulation Study

open access: yesBiomolecules, 2023
The myelin sheath provides insulation to the brain’s neuron cells, which aids in signal transmission and communication with the body. Degenerated myelin hampers the connection between the glial cells, which are the front row responders during traumatic ...

A space-fractional cable equation for the propagation of action potentials in myelinated neurons [PDF]

open access: yes, 2020
Myelinated neurons are characterized by the presence of myelin, a multilaminated wrapping around the axons formed by specialized neuroglial cells. Myelin acts as an electrical insulator and therefore, in myelinated neurons, the action potentials do not ...

Peripheral Nerve Diffusion Tensor Imaging: Assessment of Axon and Myelin Sheath Integrity. [PDF]

open access: yesPLoS ONE, 2015
To investigate the potential of diffusion tensor imaging (DTI) parameters as in-vivo biomarkers of axon and myelin sheath integrity of the median nerve in the carpal tunnel as validated by correlation with electrophysiology.MRI examinations at 3T ...

The effect of vascular graft and human umbilical cord blood-derived CD34+ stem cell on peripheral nerve healing [PDF]

open access: yes, 2018
AIM: There are many trials concerning peripheral nerve damage causes and treatment options. Unfortunately, nerve damage is still a major problem regarding health, social and economic issues.

Pathological Insights From Quantitative Susceptibility Mapping and Diffusion Tensor Imaging in Ice Hockey Players Pre and Post-concussion

open access: yesFrontiers in Neurology, 2018
Myelin sensitive MRI techniques, such as diffusion tensor imaging and myelin water imaging, have previously been used to reveal changes in myelin after sports-related concussions.
