Drosophila SPG12 ortholog, reticulon-like 1, governs presynaptic ER organization and Ca2+ dynamics

Neuronal endoplasmic reticulum (ER) appears continuous throughout the cell. Its shape and continuity are influenced by ER-shaping proteins, mutations in which can cause distal axon degeneration in Hereditary Spastic Paraplegia (HSP). We therefore asked how ...

Diversity of Cortico-descending Projections: Histological and Diffusion MRI Characterization in the Monkey

Jean-Philippe Thiran, Graham Knott, Maxime Descoteaux, Giorgio Innocenti, Tim Bjørn Dyrby

The axonal composition of cortical projections originating in premotor, supplementary motor (SMA), primary motor (a4), somatosensory and parietal areas and descending towards the brain stem and spinal cord was characterized in the monkey with histological ...

A microfabricated nerve-on-a-chip platform for rapid assessment of neural conduction in explanted peripheral nerve fibers

Sandra Gribi, Stéphanie Lacour, Diego Ghezzi, Sophie du Bois de Dunilac

Peripheral nerves are anisotropic and heterogeneous neural tissues. Their complex physiology restricts realistic in vitro models, and high resolution and selective probing of axonal activity. Here, we present a nerve-on-a-chip platform that enables rapid e ...

Long-term usability and bio-integration of polyimide-based intraneural stimulating electrodes

Silvestro Micera, Grégoire Courtine, Nawal Noëlle Kinany, Quentin Barraud, Marco Capogrosso, Stanisa Raspopovic, Sophie Marie Marthe Wurth, Alessandra Piersigilli, Jacopo Rigosa, Jérôme Gandar

Stimulation of peripheral nerves has transiently restored lost sensation and has the potential to alleviate motor deficits. However, incomplete characterization of the long-term usability and bio-integration of intra-neural implants has restricted their us ...

Influencing axon regeneration after spinal cord injury

Mark Andrew Anderson

Spinal cord injury (SCI) results in a severing of axonal connections that leads to permanent sensorimotor deficits. In cases of incomplete injury, rehabilitation paradigms have been reported to be successful in improving behavioral outcome in humans with S ...

Preferential Enhancement of Sensory and Motor Axon Regeneration by Combining Extracellular Matrix Components with Neurotrophic Factors

Silvestro Micera, Daniel Santos

After peripheral nerve injury, motor and sensory axons are able to regenerate but inaccuracy of target reinnervation leads to poor functional recovery. Extracellular matrix (ECM) components and neurotrophic factors (NTFs) exert their effect on different ne ...

Focal release of neurotrophic factors by biodegradable microspheres enhance motor and sensory axonal regeneration in vitro and in vivo

Silvestro Micera, Daniel Santos

Neurotrophic factors (NTFs) promote nerve regeneration and neuronal survival after peripheral nerve injury. However, drawbacks related with administration and bioactivity during long periods limit their therapeutic application. In this study, PLGA microsph ...

Wlds-mediated protection of dopaminergic fibers in an animal model of Parkinson disease

Patrick Aebischer, Bernard Schneider

Parkinson disease (PD) is characterized by the progressive degeneration of substantia nigra dopaminergic neurons projecting to the striatum. Since the deficit in striatal dopamine is the main cause of PD symptoms, it appears critical to preserve axon termi ...

Simultaneous GDNF and BDNF application leads to increased motoneuron survival and improved functional outcome in an experimental model for obstetric brachial plexus lesions

Patrick Aebischer, Eric Garrison Fine

Motoneurons of the neonate rat respond to proximal axonal injury with morphologic and functional changes and ultimately with neuronal death. Recent studies showed that both glial cell-line-derived neurotrophic factor (GDNF) and brain-derived neurotrophic f ...
