Project Grant R01HL181480
- This Project Grant award from the National Heart, Lung, and Blood Institute (NHLBI), under the Cardiovascular Diseases Research program (CFDA 93.837), provides $644,687 to the University of Missouri System to conduct research on a neural circuit in the brain that contributes to hypertension associated with obstructive sleep apnea. The research aims to determine how this "orexin-CRH-NTS" circuit facilitates the peripheral chemoreflex and leads to sympathoexcitation and hypertension,...
- This $673,512 Project Grant awarded by the National Heart Lung and Blood Institute under the Cardiovascular Diseases Research program (CFDA 93.837) supports research by the University of California, San Francisco (UCSF) to investigate the neural mechanisms underlying breathing rhythms. The project aims to determine whether the subconscious breathing rhythm arises from an autonomous oscillator or reciprocal inhibition between key neuronal populations in the brainstem. UCSF will use advanced mouse...
- This Project Grant award from the National Heart, Lung, and Blood Institute (CFDA 93.837 - Cardiovascular Diseases Research) aims to elucidate the complex relationship between obstructive sleep apnea (OSA) and cardiovascular disease (CVD). The $1,296,660 award supports a 24-month research project that will employ a "bed to bench" approach integrating clinical, computational, and in vitro techniques. Key objectives include developing and validating a mathematical model to quantify...
- This $782,473 federal Project Grant award from the National Heart Lung and Blood Institute (CFDA 93.837 Cardiovascular Diseases Research) supports research to improve understanding of the pathogenesis of sleep apnea using novel imaging techniques during sleep. The project aims to characterize the site and pattern of airway collapse as well as how upper airway anatomy mediates this collapse, which could provide new insights to guide optimal therapies, particularly for patients who cannot tolerate...
- This $146,703 Project Grant award from the National Heart, Lung, and Blood Institute (CFDA 93.837 - Cardiovascular Diseases Research) supports research to characterize the cellular and molecular mechanisms underlying respiratory control dysfunction in hypertension. The principal investigator will use electrophysiology and imaging approaches to study the role of the retrotrapezoid nucleus (RTN) in regulating the respiratory response to changes in CO2/H+ in spontaneously hypertensive rats. The...
- The National Heart, Lung, and Blood Institute (NHLBI) awarded a $1,415,112 project grant under the Cardiovascular Diseases Research program (CFDA 93.837) to the University of Nebraska Medical Center (UNMC) to evaluate a telehealth-delivered adaptive intervention for improving continuous positive airway pressure (CPAP) therapy adherence and health outcomes in adults with obstructive sleep apnea (OSA). The project aims to: 1) compare effects of motivational enhancement, device support, and...
- The University of Florida received a $149,348 Project Grant from the National Heart, Lung, and Blood Institute (CFDA 93.837 Cardiovascular Diseases Research) to conduct research on the cellular mechanisms of acute-intermittent hypercapnic-hypoxia induced phrenic motor plasticity. The project will monitor phrenic nerve activity in anesthetized rats as a proxy for respiratory motor output, with the goal of enhancing understanding of the pathways involved in phrenic long-term facilitation (PLTF)...
- The University of Kansas Medical Center Research Institute, Inc. (KUMCRI) was awarded a $774,997 project grant from the National Heart, Lung, and Blood Institute (CFDA 93.837 - Cardiovascular Diseases Research) to conduct research on the contribution of medullary pre-sympathetic neurons to the progression of breathing disorders and autonomic dysfunction in heart failure with preserved ejection fraction (HFPEF). The project aims to provide in-vivo and in-vitro neuronal activity mapping of the...
- This federal Project Grant award from the National Heart Lung and Blood Institute (CFDA 93.837 - Cardiovascular Diseases Research) provides $248,088 to the University of California, San Diego (UCSD) to conduct a mechanistic study on cardiovascular outcomes in patients with comorbid obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD), referred to as overlap syndrome (OVS). The central hypothesis is that poor cardiovascular outcomes in OVS, compared to COPD or OSA alone,...
- This federal Project Grant award of $794,661.00 was provided by the National Heart Lung and Blood Institute (CFDA 93.837 - Cardiovascular Diseases Research) to Emory University. The objective of the "SMILE (SICKLE CELL DISEASE MICROBIOLOGIC AND IMMUNOLOGIC LINKS TO HEALTH)" project is to define how higher brain regions interact with brainstem circuits to produce disordered breathing, with a focus on the persistent sensation of breathing discomfort known as dyspnea. The project aims...
The University of California, Los Angeles (UCLA) was awarded a $721,237 Project Grant from the National Heart, Lung, and Blood Institute (CFDA 93.837 Cardiovascular Diseases Research) to investigate the neural mechanisms by which inspiratory muscle training (IMT) can reduce blood pressure in patients with obstructive sleep apnea. The research project will use resting-state functional magnetic resonance imaging and magnetic resonance spectroscopy to assess changes in insula connectivity and glutamate levels within the central autonomic network, which could underlie a reduction in sympathetic tone and blood pressure. The award period runs from September 1, 2025 to June 30, 2029, and the project aims to provide insights into the neural effects of breathing training as an alternative approach to managing hypertension in obstructive sleep apnea patients.
