Accurate quantification of SGNs is critical for assessing degeneration and therapeutic interventions, but manual counting is arduous due to dense cellular crowding and unreliable nuclear markers. Because SGNs receive input from GluA2-containing AMPA receptors, the transcripts for which must be RNA-edited for calcium impermeability, we hypothesized that SGNs express high levels of the RNA-editing enzyme ADARB1. Here, we confirm enriched expression of\n                    <jats:italic toggle=\"yes\">Adarb1<\/jats:italic>\n                    transcripts in SGNs and show that anti-ADARB1 antibodies robustly label the nuclei of type I and type II SGNs from young and aged mice, adult macaques, and adult humans. Neuronal versus glial specificity was confirmed using antibodies against neurofilament heavy chain (NFH), human antigen D (HuD), GATA binding protein 3 (GATA3), and SRY-box 2 (SOX2). A blinded investigator manually counted mouse SGNs via NFH, and these were compared to automated counts of ADARB1-positive nuclei using the analyze particles function in ImageJ. A concordance correlation coefficient and Bland-Altman analysis demonstrated strong agreement between the manual and automated counts. Together, these results suggest broad utility of ADARB1 immunolabeling for automated counts of SGNs across species:\n                  <\/jats:p>","DOI":"10.1369\/00221554261490630","type":"journal-article","created":{"date-parts":[[2026,10,18]],"date-time":"2026-10-18T07:03:22Z","timestamp":1792307002000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Detection of the RNA-Editing Enzyme ADARB1 in Primary Auditory Neurons and Anti-ADARB1 Immunofluorescence as a Means for Automated Counting"],"prefix":"10.1369","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3490-9009","authenticated-orcid":false,"given":"Garner C.","family":"Fincher","sequence":"first","affiliation":[{"name":"University of Mississippi Medical Center, Jackson, MS"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Punam","family":"Thapa","sequence":"additional","affiliation":[{"name":"University of Mississippi Medical Center, Jackson, MS"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven C.","family":"Gressett","sequence":"additional","affiliation":[{"name":"University of Mississippi Medical Center, Jackson, MS"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradley J.","family":"Walters","sequence":"additional","affiliation":[{"name":"University of Mississippi Medical Center, Jackson, MS"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,18]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/0194599818769861"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/J.HEARES.2023.108832"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.heares.2009.10.009"},{"issue":"3","key":"e_1_3_4_5_2","article-title":"Why do hair cells and spiral ganglion neurons in the cochlea die during aging?","volume":"2","author":"Perez P","year":"2011","unstructured":"Perez P, Bao J, Perez P, Bao J.
