In our recent paper we show that TDP43 mislocalization and condensates in axons and neuromuscular junction cause Neurodegenration in ALS by inhibiting local synthesis of mitochondrial proteins https://t.co/sx5O45BY5Z

Mecca et al. investigate the role of muscle stem cells in SMA and show that their depletion disrupts neuromuscular junctions and leads to motor neuron loss in the spinal cord. They conclude that muscle stem cells represent potential therapeutic targets. https://t.co/wWcg0eoby2
O'Brien et al. demonstrate a link between ALS and extreme exercise in males which is potentially mediated via failed mTOR signalling at the neuromuscular junction. https://t.co/SpCnO3xKey; https://t.co/Z2ONeJPjaR
Drs. Yi Zeng, Aaron Gitler, and colleagues show that loss of TDP-43 from neuronal nuclei of human brain and disease-causing mutations in TDP-43 are associated with widespread changes in alternative polyadenylation. 🧠 @StanfordMed@NatureNeuro | https://t.co/3LtW0oV4PU

By uncovering a new mechanism that drives ALS progression and identifies a potential therapeutic target, we hope this work opens up new avenues for intervention.
Grateful to my brilliant team and collaborators for making this possible.
Thrilled to share our new work in Nature Neuroscience!
Together with amazing collaborators and led by Ariel Ionescu, we discovered that muscle-derived miR-126 controls local axonal TDP-43 synthesis and protects neuromuscular junctions in ALS.

This reveals a novel muscle-to-motor neuron communication axis, where loss of miR-126 triggers TDP-43 accumulation, NMJ disruption, and motor decline. Restoring miR-126 demonstrated neuroprotective effects in both mouse and human ALS models.
