Sensory pathway protection of cross-face nerve grafts counteracts chronic denervation in nerve grafts and improves regeneration and functional outcomes.
This study describes patterns of donor axon regeneration and myelination in the denervated recipient nerve stump and supports a mechanism where these donor axons sustain a proregenerative state to prevent deterioration in the face of chronic denervation.
Inhibition of the ErbB2 receptor with Herceptin unexpectedly enhances nerve regeneration after acute and delayed nerve repair. This finding raises the possibility of using targeted molecular therapies to improve outcomes of peripheral nerve injuries. The mechanism may involve a novel inhibitory association between ErbB2 and EGFR. Ann Neurol 2016;80:112-126.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
