However, the original study reported that Emx1-Cre is also expressed embryonically in peripheral autonomic ganglia, which could potentially affect the interpretation of targeted circuitry contributing to systemic phenotypes. Here, we report that Emx1-Cre is expressed in the afferent vagus nerve system involved in autonomic cardiorespiratory regulatory pathways. Our imaging studies revealed expression of Emx1-Cre driven tdtomato fluorescence in the afferent vagus nerve innervating the dorsal medulla of brainstem, cell bodies in the nodose ganglion, and their potential target structures at the carotid bifurcation such as the carotid sinus and the superior cervical ganglion (SCG). Photostimulation of the afferent terminals in the nucleus tractus solitarius (NTS)\n                    <jats:italic>in vitro<\/jats:italic>\n                    using Emx1-Cre driven ChR2 reliably evoked EPSCs in the postsynaptic neurons with electrophysiological characteristics consistent with the vagus afferent nerves. In addition, optogenetic stimulation targeting the Emx1-Cre expressing structures identified in this study, such as vagus nerve, carotid bifurcation, and the dorsal medulla surface transiently depressed cardiorespiratory rate in urethane anesthetized mice\n                    <jats:italic>in vivo<\/jats:italic>\n                    . Together, our study demonstrates that Emx1-IRES-Cre is expressed in the key peripheral autonomic nerve system and can modulate cardiorespiratory function independently of forebrain expression. These results raise caution when interpreting systemic phenotypes of Emx1-IRES-Cre conditional recombinant mice, and also suggest the utility of this line to investigate modulators of the afferent vagal system.\n                  <\/jats:p>","DOI":"10.1523\/eneuro.0093-22.2022","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T13:45:52Z","timestamp":1664804752000},"page":"ENEURO.0093-22.2022","source":"Crossref","is-referenced-by-count":7,"title":["Emx1-Cre Is Expressed in Peripheral Autonomic Ganglia That Regulate Central Cardiorespiratory Functions"],"prefix":"10.1523","volume":"9","author":[{"given":"Yao","family":"Ning","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey L.","family":"Noebels","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2564-0234","authenticated-orcid":false,"given":"Isamu","family":"Aiba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"393","published-online":{"date-parts":[[2022,10,3]]},"reference":[{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.1","doi-asserted-by":"publisher","DOI":"10.1126\/scitranslmed.aaa4050"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.2","doi-asserted-by":"publisher","DOI":"10.1152\/jn.00761.2018"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.3","doi-asserted-by":"publisher","DOI":"10.1002\/jez.b.21060"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.4","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0702810104"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.5","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awu259"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.6","doi-asserted-by":"publisher","DOI":"10.1016\/0925-4773(96)00544-8"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.7","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awy324"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.8","doi-asserted-by":"publisher","DOI":"10.1113\/expphysiol.2013.075192"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.9","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2012.235606"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.10","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2001.018333"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.11","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.22-15-06309.2002"},{"key":"2023041302170853000_9.5.ENEURO.0093-22.2022.12","doi-asserted-by":"crossref","unstructured":"Hsu C-W , Cerda J , Kirk JM , Turner WD , Rasmussen TL , Suarez CPF , Dickinson ME , Wythe JD (2022) EZ Clear for simple, rapid, and robust mouse whole organ clearing.
