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 ...

Spatio-temporal modeling of saltatory conduction in neurons using Poisson-Nernst-Planck treatment and estimation of conduction velocity [PDF]

open access: yesBrain Multiphysics, 2022, 2022
Action potential propagation along the axons and across the dendrites is the foundation of the electrical activity observed in the brain and the rest of the central nervous system. Theoretical and numerical modeling of this action potential activity has long been a key focus area of electro-chemical neuronal modeling.

Brain region‐specific amyloid plaque‐associated myelin lipid loss, APOE deposition and disruption of the myelin sheath in familial Alzheimer’s disease mice

open access: yesJournal of Neurochemistry, 2020
There is emerging evidence that amyloid beta (Aβ) aggregates forming neuritic plaques lead to impairment of the lipid‐rich myelin sheath and glia.

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.,
