Title: The Effects of Sleep Restriction on Endothelial Activation in pre- and post-menopausal women
The major goal of this project is to investigate molecular mechanisms of endothelial dysfunction in sleep
restriction, an emerging cardiovascular risk factor.

R56HL106041 (PI: Jelic) 2016 - 2017
Title: Vascular Endothelial Activation in Sleep Apnea
This project will determine whether intermittent hypoxia-induced cholesterol accumulation in endothelial cells alters complement inhibition leading to endothelial dysfunction and increased vascular risk in obstructive sleep apnea. .

2 R01 HL106041-06A1 (PI: Jelic) 2017 - 2021
Title: Vascular Endothelial Activation in Sleep Apnea
The goals of this project are: 1) To determine whether reduced complement inhibition promotes endothelial dysfunction in OSA and whether CPAP reverses these changes, 2) To determine whether reduced complement inhibition is mediated by cholesterol accumulation in ECs in OSA and whether CPAP reverses these changes, and 3) To determine whether statins prevent endothelial dysfunction in OSA by preserving complement inhibition using randomized design. Using an innovative approach to characterize human vascular endothelium, the proposed studies may advance our understanding of vascular dysfunction in OSA and provide the basis for clinical trials of novel therapeutic strategies, such as addition of statins to the standard CPAP therapy, for preventing and/or reversing vascular risk in OSA.
