Thus, neuroprotective drugs such as pregabalin (PGB) can improve motor function by modulating plasticity, together with anti\u2010inflammatory effects. The present work aimed to study the effects of PGB on axonal regeneration after axotomy in dystrophic and non\u2010dystrophic mice. For that, MDX and C57BL\/10 mouse strains were subjected to peripheral nerve damage and were treated with PGB (30\u2009mg\/kg\/day, i.p.) for 28 consecutive days. The treatment was carried out in mice as soon as they completed 5\u2009weeks of life, 1 week before the lesion, corresponding to the peak period of muscle degeneration in the MDX strain. Six\u2010week\u2010old mice were submitted to unilateral sciatic nerve crush and were sacrificed in the 9th week of age. The ipsi and contralateral sciatic nerves were processed for immunohistochemistry and qRT\u2013PCR, evaluating the expression of proteins and gene transcripts related to neuronal and Schwann cell activity. Cranial tibial muscles were dissected for evaluation of neuromuscular junctions using \u03b1\u2010bungarotoxin, and the myelinated axons of the sciatic nerve were analyzed by morphometry. The recovery of motor function was monitored throughout the treatment through tests of forced locomotion (rotarod) and spontaneous walking track test (Catwalk system). The results show that treatment with PGB reduced the retrograde cyclic effects of muscle degeneration\/regeneration on the nervous system. This fact was confirmed after peripheral nerve injury, showing better adaptation and response of neurons and glia for rapid axonal regeneration, with efficient muscle targeting and regain of function. No side effects of PGB treatment were observed, and the expression of pro\u2010regenerative proteins in neurons and Schwann cells was upregulated. Morphometry of the axons was in line with the preservation of motor endplates, resulting in enhanced performance of dystrophic animals. Overall, the present data indicate that pregabalin is protective and enhances regeneration of the SNP during the development of DMD, improving motor function, which can, in turn, be translated to the clinic.<\/jats:p>","DOI":"10.1096\/fj.202200411rr","type":"journal-article","created":{"date-parts":[[2022,8,23]],"date-time":"2022-08-23T11:40:42Z","timestamp":1661254842000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Pregabalin
