Blockade of central Agtr1 attenuates thirst to hypotension but not acute hypernatremia. Data in genetic knockout models are limited as systemic AngII does not stimulate thirst in mice, and Agtr1a\n                    <jats:sup>\u2212\/\u2212<\/jats:sup>\n                    mice are severely hypotensive. Therefore, we generated a novel Agtr1a\n                    <jats:sup>\u2212\/\u2212<\/jats:sup>\n                    rat using CRISPR\u2010Cas9 to produce an 11\u2010bp frame\u2010shift deletion in exon 3. Baseline mean arterial blood pressure (ABP) was approximately 10\u2009mmHg lower in Agtr1a\n                    <jats:sup>\u2212\/\u2212<\/jats:sup>\n                    vs. wild\u2010type (WT) rats with no differences in heart rate. Depressor responses to ganglionic blockade, vasopressin receptor blockade, or angiotensin converting enzyme inhibition were not different between strains. Systemic AngII (40\u2009ng\/min, IV) significantly increased water intake and mean ABP in WT rats, but these responses were absent in Agtr1a\n                    <jats:sup>\u2212\/\u2212<\/jats:sup>\n                    rats. Hypotension\u2010induced thirst produced by the vasodilator diazoxide (25\u2009mg\/kg, IV) stimulated water intake in WT but not in Agtr1a\n                    <jats:sup>\u2212\/\u2212<\/jats:sup>\n                    rats. In contrast, water intake stimulated by hypernatremia (2\u2009M NaCl, IV) or overnight water deprivation was not different between strains. These findings support a critical role for Agtr1a in thirst induced by AngII and hypotension but not by hypernatremia or overnight water deprivation.\n                  <\/jats:p>","DOI":"10.14814\/phy2.71042","type":"journal-article","created":{"date-parts":[[2026,8,8]],"date-time":"2026-08-08T05:29:38Z","timestamp":1786166978000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Thirst and blood pressure regulation in a novel angiotensin\n                    <scp>II<\/scp>\n                    receptor type 1a knockout rat"],"prefix":"10.14814","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7611-0586","authenticated-orcid":false,"given":"Caroline B.","family":"Ferreira","sequence":"first","affiliation":[{"name":"Department of Neurobiology University of Pittsburgh School of Medicine  Pittsburgh Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6317-6300","authenticated-orcid":false,"given":"Sean D.","family":"Stocker","sequence":"additional","affiliation":[{"name":"Department of Neurobiology University of Pittsburgh School of Medicine  Pittsburgh Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1139\/y74-160"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0091-3057(76)90248-3"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3565(25)31914-2"},{"issue":"2","key":"e_1_2_10_5_1","first-page":"R244","article-title":"Water deprivation\u2010induced drinking in rats: Role of angiotensin II","volume":"244","author":"Barney C.
