The history of myelin [PDF]

open access: yesExperimental Neurology, 2016
Andreas Vesalius is attributed the discovery of white matter in the 16th century but van Leeuwenhoek is arguably the first to have observed myelinated fibers in 1717. A globular myelin theory followed, claiming all elements of the nervous system except for Fontana's primitive cylinder with outer sheath in 1781. Remak's axon revolution in 1836 relegated

T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±

GDE2-Dependent Activation of Canonical Wnt Signaling in Neurons Regulates Oligodendrocyte Maturation

open access: yesCell Reports, 2020
Summary: Neurons and oligodendrocytes communicate to regulate oligodendrocyte development and ensure appropriate axonal myelination. Here, we show that Glycerophosphodiester phosphodiesterase 2 (GDE2) signaling underlies a neuronal pathway that promotes ...

Three‐Dimensional Biomimetic Aerogel Conduits with Electro‐Ionic‐Immune Coupling Reverse the Pathological Cascade of Spinal Cord Injury

open access: yesAdvanced Functional Materials, EarlyView.
A biomimetic aerogel conduit was engineered from a nanofiber of gelatin/poly(l‐lactic acid) doped with polypyrrole nanoparticles, integrated with tannic acid and Mg2+. This “electro‐ionic‐immune” strategy mimicked spinal cord properties, reduced calcium overload, inflammation, oxidative damage, promoted neural stem cell differentiation, suppressed ...

MRI diagnosis of cortical dysplasia in the immature brain

open access: yesЭпилепсия и пароксизмальные состояния, 2020
Introduction. Cortical dysplasias (CDs) encompass a wide variety of disorders that in most cases lead to epilepsy, especially in infants and young children.

lnc’edin to Myelin [PDF]

open access: yesNeuron, 2017
Long non-coding RNAs (lncRNAs) have been implicated in numerous developmental processes. In a technical and bioinformatics tour-de-force, He et al. (2017) provide critical insight into the dynamics of lncRNA expression, function, and mechanism during oligodendrocyte development and after injury.

Astrocytes Promote Myelination in Response to Electrical Impulses [PDF]

open access: yes, 2006
SummaryMyelin, the insulating layers of membrane wrapped around axons by oligodendrocytes, is essential for normal impulse conduction. It forms during late stages of fetal development but continues into early adult life.

Biointegrated Battery‐Based Electroceuticals

open access: yesAdvanced Materials, EarlyView.
Biointegrated batteries go beyond passive power to serve as active therapeutic platforms for delivering programmable electrical cues and bioactive agents. This review examines their mechanisms and applications and provides a framework to guide battery‐based therapeutic design and clinical translation.

Supplementation with complex milk lipids during brain development promotes neuroplasticity without altering myelination or vascular density

open access: yesFood & Nutrition Research, 2015
Background: Supplementation with complex milk lipids (CML) during postnatal brain development has been shown to improve spatial reference learning in rats.

Qki regulates myelinogenesis through Srebp2-dependent cholesterol biosynthesis

open access: yeseLife, 2021
Myelination depends on timely, precise control of oligodendrocyte differentiation and myelinogenesis. Cholesterol is the most abundant component of myelin and essential for myelin membrane assembly in the central nervous system.
