Myelin-Associated Glycoprotein Is a Myelin Signal that Modulates the Caliber of Myelinated Axons [PDF]

The Journal of Neuroscience, 1998
Myelination increases neuronal conduction velocity through its insulating properties and an unidentified extrinsic effect that increases axonal caliber. Although it is well established that demyelination can cause axonal atrophy, the myelin molecule that regulates axonal caliber is not known.

Assessment of concurrent neoplasms and a paraneoplastic association in MOGAD

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Cases of myelin oligodendrocyte glycoprotein (MOG) antibody‐associated disease (MOGAD) co‐occurring with neoplasms have been reported. In this international, retrospective cohort study in South Korea and the USA, 16 of 445 (3.6%) patients with MOGAD had concurrent neoplasm within 2 years of MOGAD onset, resulting in a standardized incidence ...

CSF cytokine, chemokine and injury biomarker profile of glial fibrillary acidic protein (GFAP) autoimmunity

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Defining the CSF cytokine/chemokine and injury biomarker signature of glial fibrillary acidic protein (GFAP) autoimmunity can inform immunopathogenesis. CSF GFAP‐IgG‐positive samples (N = 98) were tested for 17 cytokines/chemokines, neurofilament light chain (NfL), and GFAP (ELLA, Bio‐Techne).

Regulatory effect of gut microbes on blood pressure

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 513-531, December 2022., 2022
The interaction between gut microbiota and hypertension, the genera which affect the blood pressure in taxonomic level, and the commonly used treatments to hypertension based on the gut microbes were summarized in this review. The increases of Lactobacillus, etc.

Septin/anillin filaments scaffold central nervous system myelin to accelerate nerve conduction

eLife, 2016
Myelination of axons facilitates rapid impulse propagation in the nervous system. The axon/myelin-unit becomes impaired in myelin-related disorders and upon normal aging.

The Axon-Myelin Unit in Development and Degenerative Disease

Frontiers in Neuroscience, 2018
Axons are electrically excitable, cable-like neuronal processes that relay information between neurons within the nervous system and between neurons and peripheral target tissues.

An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
By applying the tensor model, we analysed lesion orientation and the directionality of lesion expansion/contraction in multiple sclerosis. Each lesion is summarized as an ellipsoid, and the tensor model is applied to calculate lesion anisotropy. From the top to the bottom white matter atlas, surface‐in gradient segmentation and venous atlas used in the

Advances in the pathogenesis of Rett syndrome using cell models

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 532-541, December 2022., 2022
Most Rett syndrome (RTT) patients are affected by the MECP2 gene mutations. And the mutations of MECP2 have wide effects on different cell types of nervous system, including neurons, astrocytes, oligodendrocytes and microglia, which always combined together to lead to abnormalities in the whole neural network.

A preclinical mice model of multiple sclerosis based on the toxin-induced double-site demyelination of callosal and cerebellar fibers

Biological Research
Background Multiple sclerosis (MS) is an irreversible progressive CNS pathology characterized by the loss of myelin (i.e. demyelination). The lack of myelin is followed by a progressive neurodegeneration triggering symptoms as diverse as fatigue, motor ...

Optical polarization evolution and transmission in multi-Ranvier-node axonal myelin-sheath waveguides [PDF]

arXiv, 2023
In neuroscience, it is of interest to consider all possible modes of information transfer between neurons in order to fully understand processing in the brain. It has been suggested that photonic communication may be possible along axonal connections, especially through the myelin sheath as a waveguide, due to its high refractive index.
