Figure Legend Snippet: p75 receptors and Rho-signaling pathway underlie BDNF prodomain-triggered inhibition of evoked ACh release at mature NMJs. Moreover, the inhibitory effect of the BDNF prodomain (1 nM) on the evoked neuromuscular transmission depends on the endogenous activity of synaptic purinoreceptors at mature NMJs.
