To date, there are no effective treatments to directly resolve edema within the spinal cord. The aquaporin-4 (AQP4) water channel is found on plasma membranes of astrocytic endfeet in direct contact with blood vessels, the glia limitans in contact with the cerebrospinal fluid, and ependyma around the central canal. Local expression at these tissue\u2013fluid interfaces allows AQP4 channels to play an important role in the bidirectional regulation of water homeostasis under normal conditions and following trauma. In this review, we consider the available evidence regarding the potential role of AQP4 in edema after SCI. Although more work remains to be carried out, the overall evidence indicates a critical role for AQP4 channels in edema formation and resolution following SCI and the therapeutic potential of AQP4 modulation in edema resolution and functional recovery. Further work to elucidate the expression and subcellular localization of AQP4 during specific phases after SCI will inform the therapeutic modulation of AQP4 for the optimization of histological and neurological outcomes.<\/jats:p>","DOI":"10.3390\/cells12131701","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T02:23:09Z","timestamp":1687746189000},"page":"1701","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The Role of Aquaporins in Spinal Cord Injury"],"prefix":"10.3390","volume":"12","author":[{"given":"Terese A.","family":"Garcia","sequence":"first","affiliation":[{"name":"Division of Biomedical Sciences, School of Medicine, University of California, Riverside, CA 92521, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carrie R.","family":"Jonak","sequence":"additional","affiliation":[{"name":"Division of Biomedical Sciences, School of Medicine, University of California, Riverside, CA 92521, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devin K.","family":"Binder","sequence":"additional","affiliation":[{"name":"Division of Biomedical Sciences, School of Medicine, University of California, Riverside, CA 92521, USA"},{"name":"Center for Glial-Neuronal Interactions, University of California, Riverside, CA 92521, USA"},{"name":"Neuroscience Graduate Program, University of California, Riverside, CA 92521, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"996","DOI":"10.1053\/apmr.2002.33100","article-title":"Nontraumatic spinal cord injury: Demographic characteristics and complications","volume":"83","author":"New","year":"2002","journal-title":"Arch.
