Vaka V, Cunningham M, Deer E, Franks M, Ibrahim T, Amaral L, et al.
Am J Physiol Regul Integr Comp Physiol . 2019 Nov; 318(2):R256-R262. PMID: 31721604
Preeclampsia (PE) is characterized by new-onset hypertension that usually occurs in the third trimester of pregnancy and is associated with oxidative stress and angiotensin II type 1 receptor agonistic autoantibodies...

Cunningham Jr M, Vaka V, McMaster K, Ibrahim T, Cornelius D, Amaral L, et al.
Pregnancy Hypertens . 2019 Mar; 15:72-77. PMID: 30825931
Women with preeclampsia (PE) have increased mean arterial pressure (MAP), natural killer (NK) cells, reactive oxygen species (ROS), and agonistic autoantibodies to the angiotensin II type 1 receptor (AT1-AA). AT1-AA's...

Vaka V, McMaster K, Cornelius D, Ibrahim T, Jayaram A, Usry N, et al.
Am J Physiol Regul Integr Comp Physiol . 2019 Feb; 316(5):R441-R447. PMID: 30811248
Preeclampsia (PE) is characterized by new-onset hypertension during pregnancy and is associated with immune activation and placental oxidative stress. Mitochondrial dysfunction is a major source of oxidative stress and may...

Vaka V, McMaster K, Cunningham Jr M, Ibrahim T, Hazlewood R, Usry N, et al.
Hypertension . 2018 Jul; 72(3):703-711. PMID: 30012871
Placental ischemia is believed to be the initial event in the development of preeclampsia. Mitochondrial dysfunction is a cause of reactive oxygen species (ROS) generation and oxidative stress, however, there...

Cunningham Jr M, Castillo J, Ibrahim T, Cornelius D, Campbell N, Amaral L, et al.
Hypertension . 2018 Mar; 71(5):886-893. PMID: 29555668
Women with preeclampsia produce AT1-AA (agonistic autoantibodies to the angiotensin II type 1 receptor), which stimulate reactive oxygen species, inflammatory factors, and hypertensive mechanisms (ET [endothelin] and sFlt-1 [soluble fms-like...

Faulkner J, Amaral L, Cornelius D, Cunningham M, Ibrahim T, Heep A, et al.
Am J Physiol Regul Integr Comp Physiol . 2016 Dec; 312(1):R125-R131. PMID: 27903510
Autoantibodies to the ANG II type I receptor (AT-AA) are associated with preeclampsia (PE). We found that vitamin D supplementation reduced AT-AA and blood pressure (MAP) in the RUPP rat...

Cunningham Jr M, Williams J, Amaral L, Usry N, Wallukat G, Dechend R, et al.
Hypertension . 2016 Oct; 68(5):1308-1313. PMID: 27698062
Preeclamptic women produce agonistic autoantibodies to the angiotensin II type 1 receptor (AT1-AA) and exhibit increased blood pressure (mean arterial pressure), vascular sensitivity to angiotensin II (ANG II), and display...
