Extent and mechanism of sealing in transected giant axons of squid and earthworms [PDF]

open access: yes, 1994
Transected axons are often assumed to seal at their cut ends by the formation of continuous membrane barriers that allow for the restoration of function in the axonal stumps.

Reduced axonal diameter of peripheral nerve fibres in a mouse model of Rett syndrome [PDF]

open access: yes, 2017
Rett syndrome (RTT) is a neurological disorder characterized by motor and cognitive impairment, autonomic dysfunction and a loss of purposeful hand skills.

Human organ donor-derived vagus nerve biopsies allow for well-preserved ultrastructure and high-resolution mapping of myelinated and unmyelinated fibers

open access: yesScientific Reports, 2021
The vagus nerve provides motor, sensory, and autonomic innervation of multiple organs, and electrical vagus nerve stimulation (VNS) provides an adjunctive treatment option for e.g. medication-refractory epilepsy and treatment-resistant depression.

Three‐dimensional architecture of the subepithelial corpuscular nerve ending in the rat epiglottis reconstructed by array tomography with scanning electron microscopy

open access: yesJournal of Comparative Neurology, Volume 531, Issue 17, Page 1846-1866, December 2023., 2023
Laryngeal laminar nerve endings were reconstructed from serial ultrathin sections. Several terminal parts of the endings entered into the epithelial layer and attached to the basal epithelial cells, suggesting the interaction between epithelial cells. Secretory vesicles in the nerve endings may release glutamate to maintain continuous discharge during ...

Mechanisms for the maintenance and eventual degradation of neurofilament proteins in the distal segments of severed goldfish Mauthner axons [PDF]

open access: yes, 1996
Cellular mechanisms that might affect the degradation of neurofilament proteins (NFPs) were examined in the distal segments of severed goldfish Mauthner axons (M-axons), which do not degenerate for more than 2 months after severance.

Axoplasm isolation from peripheral nerve [PDF]

open access: yesDevelopmental Neurobiology, 2009
AbstractLocalized changes in the composition of axonal cytoplasm (axoplasm) are critical for many biological processes, including axon guidance, responses to injury, neurite outgrowth, and axon‐glia interactions. Biochemical and molecular studies of these mechanisms have been heavily focused on in vitro systems because of the difficulty of obtaining ...

Defined Tau Phosphospecies Differentially Inhibit Fast Axonal Transport Through Activation of Two Independent Signaling Pathways

open access: yesFrontiers in Molecular Neuroscience, 2021
Tau protein is subject to phosphorylation by multiple kinases at more than 80 different sites. Some of these sites are associated with tau pathology and neurodegeneration, but other sites are modified in normal tau as well as in pathological tau ...

Nerve conduction models in myelinated and unmyelinated nerves based on three-dimensional electrostatic interaction

open access: yesNeural Regeneration Research, 2018
Until now, nerve conduction has been described on the basis of equivalent circuit model and cable theory, both of which supposed closed electric circuits spreading inside and outside the axoplasm.

Schwann cell to axon transfer of ribosomes: toward a novel understanding of the role of glia in the nervous system [PDF]

open access: yes, 2008
Schwann cells play pivotal roles in the development and maintenance of the peripheral nervous system. Here, we show that intact sciatic nerve axons of mice contain a small population of ribosomes, which increases by several orders of magnitude when axons

Alphaherpesviruses and the Cytoskeleton in Neuronal Infections

open access: yesViruses, 2011
Following infection of exposed peripheral tissues, neurotropic alphaherpesviruses invade nerve endings and deposit their DNA genomes into the nuclei of neurons resident in ganglia of the peripheral nervous system.
