IL-2 is elevated in many chronic inflammatory conditions and is increased during preeclampsia (PE). PE is characterized by new-onset hypertension during pregnancy and organ dysfunction and increasing evidence indicates that proinflammatory cytokines cause hypertension and mitochondrial (mt) dysfunction during pregnancy. The reduced uterine perfusion pressure (RUPP) model of placental ischemia is a rat model of PE that we commonly use in our laboratory and we have previously shown that low doses of recombinant IL-2 can decrease blood pressure in RUPP rats. The objective of this study was to determine the effects of a low dose of recombinant IL-2 on multi-organ mt dysfunction in the RUPP rat model of PE. We tested our hypothesis by infusing recombinant IL-2 (0.05 ng\/mL) into RUPP rats on GD14 and examined mean arterial pressure (MAP), renal, placental and endothelial cell mt function compared to control RUPP. MAP was elevated in RUPP rats (n = 6) compared to controls (n = 5) (122 \u00b1 5 vs. 102 \u00b1 3 mmHg, p &lt; 0.05), but was reduced by administration of LD recombinant IL-2 (107 \u00b1 1 vs. 122 \u00b1 5 mmHg, n = 9, p &lt; 0.05). Renal, placental and endothelial mt ROS were significantly increased in RUPP rats compared to RUPP+ IL-2 and controls. Placental and renal respiration rates were reduced in RUPP rats compared to control rats but were normalized with IL-2 administration to RUPPs. These data indicate that low-dose IL-2 normalized multi-organ mt function and hypertension in response to placental ischemia.<\/jats:p>","DOI":"10.3390\/cells10102797","type":"journal-article","created":{"date-parts":[[2021,10,20]],"date-time":"2021-10-20T01:23:46Z","timestamp":1634693026000},"page":"2797","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Low Dose of IL-2 Normalizes Hypertension and Mitochondrial Function in the RUPP Rat Model of Placental Ischemia"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8004-5978","authenticated-orcid":false,"given":"Evangeline","family":"Deer","sequence":"first","affiliation":[{"name":"Department of Pharmacology and Toxicology, University of Mississippi Medical Center, Jackson, MS 39216, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7581-9182","authenticated-orcid":false,"given":"Lorena M.","family":"Amaral","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, University of Mississippi Medical Center, Jackson, MS 39216, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathan","family":"Campbell","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, University of Mississippi Medical Center, Jackson, MS 39216, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Fitzgerald","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, University of Mississippi Medical Center, Jackson, MS 39216, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Owen","family":"Herrock","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, University of Mississippi Medical Center, Jackson, MS 39216, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tarek","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, University of Mississippi Medical Center, Jackson, MS 39216, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Babbette","family":"LaMarca","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, University of Mississippi Medical Center, Jackson, MS 39216, USA"},{"name":"Department of Obstetrics and Gynecology, University of Mississippi Medical Center, Jackson, MS 39216, USA"},{"name":"Departments of Pharmacology, Physiology, and Obstetrics and Gynecology, Center for Excellence in Cardiovascular and Renal Research, University of Mississippi Medical Center, Jackson, MS 39216, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"413","DOI":"10.1111\/aji.12072","article-title":"Angiotensin II Type 1 Receptor Autoantibody (AT1-AA)-Mediated Pregnancy Hypertension","volume":"69","author":"Herse","year":"2013","journal-title":"Am.
