The myelin sheath on vertebrate axons is critical for neural impulse transmission, but whether electrically active axons are preferentially myelinated by glial cells, and if so, whether axo-glial synapses are involved, are long-standing questions of ...

Unrestrained growth of correctly oriented microtubules instructs axonal microtubule orientation
In many eukaryotic cells, directed molecular transport occurs along microtubules. Within neuronal axons, transport over vast distances particularly relies on uniformly oriented microtubules, whose plus-ends point towards the distal axon tip ...

The Parkinson’s disease–associated proteins PINK1 and Parkin mediate local mitophagy of dysfunctional mitochondria in distal neuronal axons, abrogating the need for retrograde organelle transport and ensuring rapid neuroprotection.

Local Accumulation of Axonal Mitochondria in the Optic Nerve Glial Lamina Precedes Myelination
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 ...

A chloride channel in rat and human axons [PDF]
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 ...

Cortical AAV-CNTF gene therapy combined with intraspinal mesenchymal precursor cell transplantation promotes functional and morphological outcomes after spinal cord injury in adult rats [PDF]
Ciliary neurotrophic factor (CNTF) promotes survival and enhances long-distance regeneration of injured axons in parts of the adult CNS. Here we tested whether CNTF gene therapy targeting corticospinal neurons (CSN) in motor-related regions of the ...

The Genetics of Axonal Transport and Axonal Transport Disorders
Neurons are specialized cells with a complex architecture that includes elaborate dendritic branches and a long, narrow axon that extends from the cell body to the synaptic terminal. The organized transport of essential biological materials throughout the neuron is required to support its growth, function, and viability.

Human umbilical cord mesenchymal stem cells promote peripheral nerve repair via paracrine mechanisms
Human umbilical cord-derived mesenchymal stem cells (hUCMSCs) represent a promising young-state stem cell source for cell-based therapy. hUCMSC transplantation into the transected sciatic nerve promotes axonal regeneration and functional recovery.

Interferon inhibits the release of herpes simplex virus-1 from the axons of sensory neurons
Herpes simplex virus-1 (HSV-1) has evolved mechanisms to evade the host immune system and limit the antiviral effects induced by interferon (IFN) produced by local epithelial and immune cells.

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