Cyclo His-Pro Attenuates Muscle Degeneration in Murine Myopathy Models

Johan Auwerx, Xiaoxu Li, Alessia De Masi, Tanes Imamura de Lima, Keno Strotjohann

Among the inherited myopathies, a group of muscular disorders characterized by structural and metabolic impairments in skeletal muscle, Duchenne muscular dystrophy (DMD) stands out for its devastating progression. DMD pathogenesis is driven by the progress ...

Mitophagy Activation by Urolithin A to Target Muscle Aging

Davide D'Amico, Anurag Singh

The age-related loss of skeletal muscle function starts from midlife and if left unaddressed can lead to an impaired quality of life. A growing body of evidence indicates that mitochondrial dysfunction is causally involved with muscle aging. Muscles are ti ...

Cortico-muscular connectivity is modulated by passive and active Lokomat-assisted Gait

Silvestro Micera, Fiorenzo Artoni

The effects of robotic-assisted gait (RAG) training, besides conventional therapy, on neuroplasticity mechanisms and cortical integration in locomotion are still uncertain. To advance our knowledge on the matter, we determined the involvement of motor cort ...

Wearable High-Density MXene-Bioelectronics for Neuromuscular Diagnostics, Rehabilitation, and Assistive Technologies

Silvestro Micera, Francesco Iberite, Eugenio Anselmino

High-density surface electromyography (HDsEMG) allows noninvasive muscle monitoring and disease diagnosis. Clinical translation of current HDsEMG technologies is hampered by cost, limited scalability, low usability, and minimal spatial coverage. Here, this ...

REM sleep and muscle atonia in brainstem stroke: A quantitative polysomnographic and lesion analysis study

Lukas Heydrich, Eva Blondiaux

Important brainstem regions are involved in the regulation of rapid eye movement sleep. We hypothesized that brainstem stroke is associated with dysregulated rapid eye movement sleep and related muscle activity. We compared quantitative/qualitative polysom ...

Molecular Regulation of Muscle Stem Cell Fate during Skeletal Muscle Regeneration and Aging

Sara Ancel

Muscle stem cells (MuSCs) are the primary source of myogenic progenitors during muscle repair and are essential for the long-term regenerative capacity of skeletal muscle. Following myofiber injury, MuSCs transition from a quiescent to an activated state, ...

Co-regulation of endothelial and myogenic cell fates through intercellular crosstalk in skeletal muscle

Umji Lee

Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...

Muscle activities in similar arms performing identical tasks reveal the neural basis of muscle synergies

Martina Coscia

Are the muscle synergies extracted from multiple electromyographic signals an expression of neural information processing, or rather a by-product of mechanical and task constraints? To address this question, we asked 41 right-handed adults to perform a var ...

Targeting mitochondrial bioenergetics and NAD+ metabolism during sarcopenia and regeneration of skeletal muscle

Tanja Sonntag

The progressive decline of muscle mass and function called sarcopenia is a multi-factorial process associated to frailty, disability, and low quality of life in the elderly. The co-factor nicotinamide adenine dinucleotide (NAD+) becomes a limiting factor i ...

Autologous Cell Therapy Approach for Duchenne Muscular Dystrophy using PiggyBac Transposons and Mesoangioblasts

Nicolas Mermod

Duchenne muscular dystrophy (DMD) is a lethal muscle-wasting disease currently without cure. We investigated the use of the PiggyBac transposon for full-length dystrophin expression in murine mesoangioblast (MABs) progenitor cells. DMD murine MABs were tra ...

Muscle activation variability is inversely correlated with walking speed

Auke Ijspeert, Florin Dzeladini, Cole Stewart Simpson, Amandine Grappe

Individuals with motor impairments typically walk at much slower speeds than their unimpaired counter- parts, yet their gait data is still evaluated against the relatively faster gait of healthy subjects. Therefore a good understanding of unimpaired gait a ...

Evaluation of the effects of the Arm Light Exoskeleton on movement execution and muscle activities: a pilot study on healthy subjects

Silvestro Micera, Elvira Pirondini, Martina Coscia, Massimo Bergamasco

Background: Exoskeletons for lower and upper extremities have been introduced in neurorehabilitation because they can guide the patient's limb following its anatomy, covering many degrees of freedom and most of its natural workspace, and allowing the contr ...

NAD(+) repletion improves muscle function in muscular dystrophy and counters global PARylation

Johan Auwerx, Carlos Canto Alvarez, Laurent Mouchiroud, Dongryeol Ryu, Xu Wang, Vincenzo Sorrentino, Hongbo Zhang, Keir Joe Menzies, Karim Laurent Gariani

Neuromuscular diseases are often caused by inherited mutations that lead to progressive skeletal muscle weakness and degeneration. In diverse populations of normal healthy mice, we observed correlations between the abundance of mRNA transcripts related to ...

Correlation between muscular and nerve signals responsible for hand grasping in non-human primates

Frédéric Pierre Gérald Michoud

Neuroprosthetic devices that interface with the nervous system to restore functional motor activity offer a viable alternative to nerve regeneration, especially in proximal nerve injuries like brachial plexus injuries where muscle atrophy may set in before ...

Assessing dystrophies and other muscle diseases at the nanometer scale by atomic force microscopy

Giovanni Dietler, Harald Brune, Andrzej Kulik, Nicolas Mermod, Guillaume Witz, Stefania Puttini

Aim: Atomic force microscopy nanoindentation of myofibers was used to assess and quantitatively diagnose muscular dystrophies from human patients. Materials & methods: Myofibers were probed from fresh or frozen muscle biopsies from human dystrophic patient ...

Synergistic Effects of GDNF and VEGF on Lifespan and Disease Progression in a Familial ALS Rat Model

Patrick Aebischer, Michaël Meyer

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of motor neurons in the brain and spinal cord. We have recently shown that human mesenchymal stem cells (hMSCs) modified to release glial cell li ...

Undirected compensatory plasticity contributes to neuronal dysfunction after severe spinal cord injury

Grégoire Courtine, Quentin Barraud, Pavel Musienko, Rubia van den Brand, Lucia Florinda Friedli Wittler, Janine Beauparlant

Severe spinal cord injury in humans leads to a progressive neuronal dysfunction in the chronic stage of the injury. This dysfunction is characterized by premature exhaustion of muscle activity during assisted locomotion, which is associated with the emerge ...

Direct Muscle Delivery of GDNF With Human Mesenchymal Stem Cells Improves Motor Neuron Survival and Function in a Rat Model of Familial ALS

Patrick Aebischer

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease in which there is a progressive loss of motor neurons and their connections to muscle, leading to paralysis. In order to maintain muscle connections in a rat model of familial ALS (FA ...
