Myelin-like sheaths in copepod axons [PDF]

open access: yesNature, 1999
Copepods, the small planktonic crustaceans that are the most abundant metazoans in the oceans, are so successful partly because they have an escape response that accelerates them to 200 body lengths per second within milliseconds1,3. We find that nerve fibres of many copepods seem to be designed for rapid signalling.

Effect of Sox10 on remyelination of the hippocampus in cuprizone‐induced demyelinated mice

open access: yesBrain and Behavior, 2020
Objective The low number of oligodendrocytes (OLs) in the hippocampus of patients with schizophrenia suggests that hippocampal demyelination is changed in this condition. Sox10 is expressed throughout OL development.

Asymptotic construction of pulses in the Hodgkin Huxley model for myelinated nerves [PDF]

open access: yes, 2005
A quantitative description of pulses and wave trains in the spatially discrete Hodgkin-Huxley model for myelinated nerves is given. Predictions of the shape and speed of the waves and the thresholds for propagation failure are obtained.

Peroxisomal dysfunctions cause lysosomal storage and axonal Kv1 channel redistribution in peripheral neuropathy [PDF]

open access: yes, 2017
Impairment of peripheral nerve function is frequent in neurometabolic diseases, but mechanistically not well understood. Here, we report a novel disease mechanism and the finding that glial lipid metabolism is critical for axon function, independent of ...

Simulation of nerve fiber based on anti-resonant reflecting optical waveguide

open access: yesScientific Reports, 2022
Light and optical techniques are widely used for the diagnosis and treatment of neurological diseases as advanced methods. Understanding the optical properties of nervous tissue and nerve cells is vital.

Autoreactive lymphocytes in multiple sclerosis: Pathogenesis and treatment target

open access: yesFrontiers in Immunology, 2022
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) characterized by destruction of the myelin sheath structure.

Neuroinflammation and myelin status in Alzheimer’s disease, Parkinson’s disease, and normal aging brains: A small sample study [PDF]

open access: yes, 2019
Microglia and astrocytes play important roles in mediating the immune processes and nutritional support in the central nervous system (CNS). Neuroinflammation has been indicated in the progression of neurodegenerative diseases Alzheimer’s disease (AD ...

Early myelination involves the dynamic and repetitive ensheathment of axons which resolves through a low and consistent stabilization rate

open access: yeseLife, 2023
Oligodendrocytes in the central nervous system exhibit significant variability in the number of myelin sheaths that are supported by each cell, ranging from 1 to 50 (1-8). Myelin production during development is dynamic and involves both sheath formation

MicroRNA-23a promotes myelination in the central nervous system. [PDF]

open access: yes, 2013
Demyelinating disorders including leukodystrophies are devastating conditions that are still in need of better understanding, and both oligodendrocyte differentiation and myelin synthesis pathways are potential avenues for developing treatment ...

Towards in vivo g-ratio mapping using MRI: unifying myelin and diffusion imaging [PDF]

open access: yes, 2020
The g-ratio, quantifying the comparative thickness of the myelin sheath encasing an axon, is a geometrical invariant that has high functional relevance because of its importance in determining neuronal conduction velocity.
