In a prior pilot study, Agrin, neuregulin\u20101 (NRG1), and acetylcholine (ACh) enhanced early (1\u2010month) reinnervation after RLN injury. The aims of the current study were to (1) assess if these effects persist in a 3\u2010month RLN injury model and (2) test whether Agrin\/ACh\/NRG1 promotes regeneration after sciatic nerve (SN) transection, with relevance to nerve repair beyond the larynx.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Adult C57BL\/6 mice underwent unilateral RLN or SN transection with injections into the thyroarytenoid or gastrocnemius, respectively.

Functional recovery was evaluated using videolaryngoscopy and electromyography (EMG) for RLN injury, and gait analysis with EMG for the SN model.
