In this study, we investigated whether oral supplementation with antioxidant carnosine, a natural dipeptide, could stimulate endogenous production of these neuroprotective molecules within the neural and muscle microenvironment 6\u2009weeks after SCI. We assessed the effects of 6\u2010week carnosine treatment in female Zucker rats, administered either before (CB\u2010I) or after injury (CA\u2010I). The impact of thoracic SCI and carnosine treatment was evaluated in\n                    <jats:styled-content>in<\/jats:styled-content>\n                    \/active microenvironments of fore limb and hind limb muscles, along with their corresponding innervation regions. To better understand how carnosine treatment affects the neural microenvironment, we analysed mRNA expression levels of neurotrophic factors and their receptors. We also examined molecules that may indicate which cell types are involved in producing or responding to BDNF or GDNF in the spinal cord. Six weeks after thoracic SCI, we observed better locomotor recovery in CA\u2010I compared to CB\u2010I treated rats. In the hind limb, posttraumatic carnosine treatment prevented SCI\u2010induced reductions in BDNF and GDNF protein levels. Additionally, this treatment blocked the SCI\u2010induced reduction of GDNF protein levels and the oligodendrocyte\u2010specific gene Olig2 in the lumbar and cervical spinal cord segments. Interestingly, the postinjury treatment elevated the gene expression in BDNF receptor\u2010 and astrocyte\u2010specific genes in the cervical segments. The finding that carnosine may prevent BDNF and GDNF declines in denervated hind limb muscles positions this dipeptide as a promising candidate for inclusion in future combination therapies.\n
