This research shows that the sympathetic nervous system is disrupted at the earliest stages of ALS, despite sympathetic neurons themselves remaining intact. Early loss of signalling receptors may contribute to muscle degeneration and disease progression, identifying new opportunities for earlier diagnosis and therapies that preserve muscle function and improve patient outcomes.

This research investigates toxic protein fragments involved in amyotrophic lateral sclerosis (ALS). By studying two TDP-43 fragments in mice and neurons, the work shows that specific fragments cause greater movement deficits and protein aggregation. Identifying the most harmful fragments advances understanding of ALS mechanisms and supports development of targeted neuroprotective therapies.
