Neuromuscular Junction Failure in Sarcopenia Paper

“Neuromuscular junction failure in sarcopenia is linked to NaV1.4 loss and reversed by ClC-1 inhibition,” identifies impaired communication between nerve and muscle as an important and potentially reversible contributor to age-related weakness. The study links neuromuscular transmission failure to loss of NaV1.4 at the neuromuscular junction in older humans and rodent models and shows that ClC-1 inhibition can restore muscle excitability and improve function in aged animals. These findings broaden the understanding of sarcopenia and point toward new therapeutic strategies to preserve strength, mobility, and independence in older adults.
