Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults

Johan Auwerx, Patrick Aebischer, Pénélope Andreux

Targeting mitophagy to activate the recycling of faulty mitochondria during aging is a strategy to mitigate muscle decline. We present results from a randomized, placebo-controlled trial in middle-aged adults where we administer a postbiotic compound Uroli ...

Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults A Randomized Clinical Trial

Patrick Aebischer

IMPORTANCE Aging is associated with a decline in mitochondrial function and reduced exercise capacity. Urolithin A is a natural gut microbiome-derived food metabolite that has been shown to stimulate mitophagy and improve muscle function in older animals a ...

Astrocyte-targeting RNA interference against mutated superoxide dismutase 1 induces motoneuron plasticity and protects fast-fatigable motor units in a mouse model of amyotrophic lateral sclerosis

Patrick Aebischer, Bernard Schneider, Nathalie Marie Géraldine Bernard, Cylia Cloé Rochat

In amyotrophic lateral sclerosis (ALS) caused by SOD1 gene mutations, both cell-autonomous and noncell-autonomous mechanisms lead to the selective degeneration of motoneurons (MN). Here, we evaluate the therapeutic potential of gene therapy targeting mutat ...

Direct supplementation with Urolithin A overcomes limitations of dietary exposure and gut microbiome variability in healthy adults to achieve consistent levels across the population

Johan Auwerx, Patrick Aebischer, Pénélope Andreux, Davide D'Amico

Background Urolithin A (UA) is produced by gut microflora from foods rich in ellagitannins. UA has been shown to improve mitochondrial health preclinically and in humans. Not everyone has a microbiome capable of producing UA, making supplementation with UA ...

Evolution of the neurochemical profiles in the G93A-SOD1 mouse model of amyotrophic lateral sclerosis

Rolf Gruetter, Patrick Aebischer, Bernard Schneider, Hongxia Lei, Carole Poitry-Yamate, Elisabeth Anne Dirren

In vivo (1)H magnetic resonance spectroscopy ((1)H-MRS) investigations of amyotrophic lateral sclerosis (ALS) mouse brain may provide neurochemical profiles and alterations in association with ALS disease progression. We aimed to longitudinally follow neur ...

The mitophagy activator urolithin A is safe and induces a molecular signature of improved mitochondrial and cellular health in humans

Johan Auwerx, Patrick Aebischer, Pénélope Andreux, Dongryeol Ryu, Frederic Burdet, Anurag Singh

Urolithin A (UA) is a natural dietary, microflora-derived metabolite shown to stimulate mitophagy and improve muscle health in old animals and in preclinical models of aging(1). Here, we report the results of a first-in-human clinical trial in which we adm ...

Parkin functionally interacts with PGC-1 proportional to to preserve mitochondria and protect dopaminergic neurons

Johan Auwerx, Patrick Aebischer, Graham Knott, Bernard Schneider, Davide D'Amico, Darren Moore, Norman Lionel Moullan, Nathalie Marie Géraldine Bernard, Lu Zheng

To understand the cause of Parkinson's disease (PD), it is important to determine the functional interactions between factors linked to the disease. Parkin is associated with autosomal recessive early-onset PD, and controls the transcription of PGC-1a, a m ...

A subcutaneous cellular implant for passive immunization against amyloid-beta reduces brain amyloid and tau pathologies

Patrick Aebischer, Bernard Schneider, Vanessa Laversenne, Aurélien Lathuilière, Marco Stampanoni

Passive immunization against toxic misfolded proteins could offer protection against neurodegenerative disease. LathuiliSre et al. report the development of a retrievable device to encapsulate cells secreting recombinant anti-amyloid-beta antibodies. When ...
