Acutely denervated muscle EVs reshape neuronal mitochondrial metabolism via retrograde signaling to rescue peripheral nerve injury

Key Points

• Acutely denervated muscle-derived extracellular vesicles reshape neuronal mitochondrial metabolism, supporting recovery.
• Key evidence shows that these vesicles significantly enhance mitochondrial function after peripheral nerve injury.
• Analysis reveals that retrograde signaling plays a crucial role in mediating the metabolic effects of these vesicles on neurons.
• This study highlights the potential for utilizing extracellular vesicles in developing therapies for nerve damage, underscoring the need for further research.
