Local Accumulation of Axonal Mitochondria in the Optic Nerve Glial Lamina Precedes Myelination
Frontiers in Neuroanatomy, 2021 Mitochondria are essential for neurons and must be optimally distributed along their axon to fulfill local functions. A high density of mitochondria has been observed in retinal ganglion cell (RGC) axons of an unmyelinated region of the optic nerve ...

Origins of Neural Progenitor Cell-Derived Axons Projecting Caudally after Spinal Cord Injury. [PDF]
, 2019 Neural progenitor cells (NPCs) transplanted into sites of spinal cord injury (SCI) extend large numbers of axons into the caudal host spinal cord. We determined the precise locations of neurons in the graft that extend axons into the caudal host spinal ...

The Requirement of Sox2 for the Spinal Cord Motor Neuron Development of Zebrafish
Frontiers in Molecular Neuroscience, 2020 Sex-determining region Y box 2 (Sox2), expressed in neural tissues, plays an important role as a transcription factor not only in the pluripotency and proliferation of neuronal cells but also in the opposite function of cell differentiation. Nevertheless,

Predicting Axonal Response to Molecular Gradients with a Computational Model of Filopodial Dynamics [PDF]
, 2004 Axons are often guided to their targets in the developing nervous system by attractive or repulsive molecular concentration gradients. We propose a computational model for gradient sensing and directed movement of the growth cone mediated by filopodia ...

Intra-axonal mechanisms driving axon regeneration
Brain Research, 2020 Traumatic injury to the peripheral and central nervous systems very often causes axotomy, where an axon loses connections with its target resulting in loss of function. The axon segments distal to the injury site lose connection with the cell body and degenerate.

Axon degeneration: Linking axonal bioenergetics to myelin [PDF]
Journal of Cell Biology, 2016 The mechanisms by which axonal degeneration occurs, even in the presence of apparently normal myelin sheaths, remain unknown. In this issue, Yin et al. (2016. J. Cell Biol. https://doi.org/10.1083/jcb.201607099) study mutant mice in which proteolipid protein is replaced by the peripheral myelin protein P0 and describe a number of early axonal ...

Optogenetic Interrogation of Functional Synapse Formation by Corticospinal Tract Axons in the Injured Spinal Cord [PDF]
, 2016 To restore function after injury to the CNS, axons must be stimulated to extend into denervated territory and, critically, must form functional synapses with appropriate targets. We showed previously that forced overexpression of the transcription factor

Dynamic m6A modification regulates local translation of mRNA in axons
Nucleic Acids Research, 2017 N 6-methyladenosine (m6A) is a reversible modification in mRNA and has been shown to regulate processing, translation and decay of mRNA. However, the roles of m6A modification in neuronal development are still not known.

Neuron Names: A Gene- and Property-Based Name Format, With Special Reference to Cortical Neurons
Frontiers in Neuroanatomy, 2019 Precision in neuron names is increasingly needed. We are entering a new era in which classical anatomical criteria are only the beginning toward defining the identity of a neuron as carried in its name.

A chloride channel in rat and human axons [PDF]
, 1991 Current recordings from single chloride channels were obtained from excised and cell-attached patches of rat and human axons. In rat axons the channels showed an outwardly rectifying current-voltage relationship with a slope conductance of 33 pS at ...
