Abstract

Neurotrophin signaling at the neuromuscular junction modulates cholinergic transmission and enhances neuromuscular transmission via the tropomyosin-related kinase receptor subtype B (TrkB). A novel flavonoid, 7,8-dihydroxyflavone (7,8-DHF), selectively activates TrkB receptors. Using TrkBF616A mice that are susceptible to specific inhibition of TrkB activity by 1NMPP1, we show that neuromuscular transmission is enhanced by 7,8-DHF (∼32%) via activation of TrkB in diaphragm muscle. The small molecule 7,8-DHF may constitute a novel therapy to improve neuromuscular function.
