Emerging cellular themes in leukodystrophies

Frontiers in Cell and Developmental Biology, 2022
Leukodystrophies are a broad spectrum of neurological disorders that are characterized primarily by deficiencies in myelin formation. Clinical manifestations of leukodystrophies usually appear during childhood and common symptoms include lack of motor ...

Remyelination alters the pattern of myelin in the cerebral cortex

bioRxiv, 2020
Destruction of oligodendrocytes and myelin sheaths in cortical gray matter profoundly alters neural activity and is associated with cognitive disability in multiple sclerosis (MS).

Studies on cultured Schwann cells: the induction of myelin synthesis, and the control of their proliferation by a new growth factor [PDF]

, 1981
We have recently described the use of immunological methods to identify and purify rat Schwann cells. In dissociated cultures of neonatal sciatic nerve, all of the cells can be identified by antigenic criteria as either Schwann cells or fibroblasts.

Mechanisms involved in the remyelinating effect of sildenafil [PDF]

, 2018
Remyelination occurs in demyelinated lesions in multiple sclerosis (MS) and pharmacological treatments that enhance this process will critically impact the long term functional outcome in the disease.

Quantitative Iron Measurements in the Basal Ganglia of NBIA Patients Using QSM: Insights From a Tertiary Center

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurodegeneration with brain iron accumulation (NBIA) comprises rare genetic disorders characterized by predominantly extrapyramidal symptoms and iron deposition in the basal ganglia. Conventional magnetic resonance imaging (MRI) detects qualitative changes but cannot accurately quantify iron accumulation. Quantitative susceptibility

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 ...

Correlated disorder in myelinated axons orientational geometry and structure

, 2017
While the ultrastructure of the myelin has been considered to be a quasi-crystalline stable system, nowadays its multiscale complex dynamics appears to play a key role for its functionality, degeneration and repair processes following neurological ...

Axonal regeneration in hippocampal and spinal cord organotypic slice cultures [PDF]

, 2010
Under normal conditions, axonal regeneration after lesions is not possible in mature CNS but can occur in embryonic and early postnatal nervous systems. In recent years, a number of possible strategies to enhance axonal regeneration and eventually treat ...

Thinning of originally-existing, mature myelin represents a nondestructive form of myelin loss in the adult CNS

Frontiers in Cellular Neuroscience
The main function of oligodendrocytes is to assemble and maintain myelin that wraps and insulates axons in the central nervous system (CNS). Traditionally, myelin structure, particularly its thickness, was believed to remain remarkably stable in ...

Neuron to Oligodendrocyte Precursor Cell Synapses: Protagonists in Oligodendrocyte Development and Myelination, and Targets for Therapeutics

Frontiers in Neuroscience, 2022
The development of neuronal circuitry required for cognition, complex motor behaviors, and sensory integration requires myelination. The role of glial cells such as astrocytes and microglia in shaping synapses and circuits have been covered in other ...
