In addition, a limitation of the current study is that we did not assess Treg function. and female DOCA-salt rats were treated with anti-CD25 to decrease Tregs. Reducing Tregs significantly improved BP only in females, therefore abolishing the sex difference in the BP response to DOCA-salt. This data helps the hypothesis that Tregs protect against the development of hypertension and are particularly important for the control of BP in females. strong class=”kwd-title” Keywords: Hypertension, Sex, Gender, Tregs, Kidney, Swelling Graphical Abstract Intro Hypertension is the most common risk element for cardiovascular disease, which is the leading cause of death among both men and women, causing over 18 million deaths a 12 months worldwide1. Although the mechanisms controlling blood pressure (BP) in either sex remain largely unfamiliar, there is an ever-expanding literature base implicating a role for chronic swelling in the development of hypertension2C4. More specifically, T cells have been shown to be crucial in the development of hypertension using multiple experimental models5. T cells have also been suggested to contribute to sex variations in BP control6, 7, yet little is known concerning the relative part of different T cell subtypes in BP control in males vs. females. The DOCA-salt model of hypertension incorporates the activation of mineralocorticoid receptors and a high salt intake, both of which happen to be shown to perform key functions in the development of hypertension as well as swelling8, 9. Indeed, treatment of male DOCA-salt rats with the lymphocyte inhibitor, mycophenolate mofetil, attenuates DOCA-salt induced raises in BP10, and male Rag1?/? mice lacking B and T cells have a blunted increase in BP to DOCA-salt treatment vs. wildtype control mice5. These data support a central part for T cells in the development of hypertension in DOCA-salt hypertension in males. However, not all T cell subtypes are pro-hypertensive2, 11. T regulatory cells (Tregs) are an anti-inflammatory, anti-hypertensive subset of T cells that suppress immune effector function and attenuate raises in BP12C15. Interestingly, male DOCA-salt rats have previously been shown to exhibit a decrease in circulating and renal anti-inflammatory Tregs16, and this GU/RH-II may further contribute to raises in BP. Our lab offers previously reported that there are sex variations in the renal T cell profile in both spontaneously hypertensive rats (SHR) and angiotensin II-induced hypertensive rats; where females have more Tregs than males3, 17. Moreover, female SHR show a BP-dependent upregulation of Tregs that corresponds to a lower BP when compared to 4-Pyridoxic acid males18, suggesting that Tregs are particularly important in BP control in females. However, there is a lack of info in the literature regarding the effect of DOCA-salt on T cells in females. The goal of the current study was to determine the impact of sex on renal T cell profiles in DOCA-salt hypertensive males and females. Therefore, initial experiments in the current study measured the renal T cell profile using circulation cytometric analysis in male and female DOCA-salt hypertensive rats. Consistent with earlier studies, female DOCA-salt rats have more renal Tregs than males. Additional experiments further tested the hypothesis that higher numbers of Tregs in females protect against DOCA-salt induced raises in BP and kidney injury to a greater degree than in male rats.

Animals Nine to ten-week-old male and woman Sprague Dawley (SD) rats were purchased from Envigo, Inc. (Indianapolis, IN) between November 2017 and December 2018.

Rats were housed in moisture and heat controlled, light-cycled quarters, and managed 4-Pyridoxic acid on standard chow (Teklad Global 18% Protein Rodent Diet 2918; cat # 2918C091619M). At 10 weeks of age, all rats were anesthetized and a uni-nephrectomy (UNX) was performed. After one week of recovery, DOCA-salt rats received a subcutaneous 21-day time slow-release deoxycorticosterone acetate (DOCA) pellet (200 mg) with saline (0.9%) to drink. UNX control rats received tap water to drink (n=11C12). A subset of DOCA-salt rats were implanted with telemetry products (Data Sciences International, St Paul, MN; cat # 270-0180-001) at the same time as the UNX for the measurement of imply arterial pressure (MAP) for 3 weeks. Additional male and female DOCA and UNX rats were euthanized after one week of DOCA-salt (n=12) for cells collection.Consequently, initial experiments in the current study measured the renal T cell profile using flow cytometric analysis in male and female DOCA-salt hypertensive rats. anti-inflammatory Tregs than males. Additional male and female DOCA-salt rats were treated with anti-CD25 to decrease Tregs.
