Abstract
ABSTRACT The RUPP rat model of Preeclampsia exhibits hypertension (MAP), cytolytic natural killer (cNK) cells, tumor necrosis factor alpha (TNF-α) and mitochondrial Reactive Oxygen Species (mt ROS). Objective: Does TNF-α blockade with ETAN (Etanercept) decrease cNK cell and mt ROS in RUPP rats. Methods: On gestational day 14, RUPP surgery was performed, ETAN (0.4 mg/kg) was administered on day 18, MAP, blood and tissues collected on 19. Results:MAP, cytolytic NK cells and mt ROS were elevated in RUPP vs. NP and normalized with ETAN. Conclusion: TNF-α blockade lowered blood pressure and improve inflammation and organ function in response to placental ischemia.
