In-vivo single neuron axotomy triggers axon regeneration to restore synaptic density in specific cortical circuits

To what extent, how and when axons respond to injury in the highly interconnected grey matter is poorly understood. Here we use two-photon imaging and focused ion beam-scanning electron microscopy to explore, at synaptic resolution, the regrowth capacity o ...

PDMS Microchannel Regenerative Peripheral Nerve Interface

Stéphanie Lacour, Katherine Marie Musick

We have fabricated a soft silicone structure to support the regeneration of a sciatic nerve. The device consists of 70 parallel (120 x 110 mu m(2)) channels through which axons extend and then reconnect to the muscles on the other side of the device. Throu ...

Native Architecture of the Centriole Proximal Region Reveals Features Underlying Its 9-Fold Radial Symmetry

Pierre Gönczy, Davide Demurtas, Paul Guichard, Isabelle Fluckiger, Aitana Neves da Silva, Norbert Majubu

Centrioles are cylindrical microtubule-based structures whose assembly is critical for the formation of cilia, flagella, and centrosomes. The centriole proximal region harbors a cartwheel that dictates the 9-fold symmetry of centrioles. Although the cartwh ...

Investigation of field and diffusion time dependence of the diffusion-weighted signal at ultrahigh magnetic fields

Rolf Gruetter, Yohan Van de Looij, Nicolas Kunz

Over the last decade, there has been a significant increase in the number of high-magnetic-field MRI magnets. However, the exact effect of a high magnetic field strength (B0 ) on diffusion-weighted MR signals is not yet fully understood. The goal of this s ...

A computer-assisted multi-electrode patch-clamp system

Henry Markram, Rodrigo de Campos Perin

The patch-clamp technique is today the most well-established method for recording electrical activity from individual neurons or their subcellular compartments. Nevertheless, achieving stable recordings, even from individual cells, remains a time-consuming ...

Imaging green fluorescent protein-labeled neurons using light and electron microscopy

Graham Knott

The ability to observe axons and dendrites with transmission electron microscopy (EM) after they have been previously imaged live with laser-scanning microscopy is a useful technique to study their synaptic connectivity. This protocol provides a detailed m ...

Surface Microstructures on Planar Substrates and Textile Fibers Guide Neurite Outgrowth: A Scaffold Solution to Push Limits of Critical Nerve Defect Regeneration?

Thomas Lehnert, Li Yao

The treatment of critical size peripheral nerve defects represents one of the most serious problems in neurosurgery. If the gap size exceeds a certain limit, healing can't be achieved. Connection mismatching may further reduce the clinical success. The pre ...

Spinal muscular atrophy pathogenic mutations impair the axonogenic properties of axonal-survival of motor neuron

Veronica Setola

The axonal survival of motor neuron (a-SMN) protein is a truncated isoform of SMN1, the spinal muscular atrophy (SMA) disease gene. a-SMN is selectively localized in axons and endowed with remarkable axonogenic properties. At present, the role of a-SMN in ...

Nanotopography induced contact guidance of the F11 cell line during neuronal differentiation: a neuronal model cell line for tissue scaffold development

Silvestro Micera

The F11 hybridoma, a dorsal root ganglion-derived cell line, was used to investigate the response of nociceptive sensory neurons to nanotopographical guidance cues. This established this cell line as a model of peripheral sensory neuron growth for tissue s ...

Oligodendroglia metabolically support axons and contribute to neurodegeneration

Yiming Li, Pierre Magistretti, Sylvain Eric Lengacher, Luc Pellerin, Lin Jin

Oligodendroglia support axon survival and function through mechanisms independent of myelination, and their dysfunction leads to axon degeneration in several diseases. The cause of this degeneration has not been determined, but lack of energy metabolites s ...
