Pulmonary Branch

The Pulmonary Branch conducts clinically oriented research into diseases and disorders affecting the lungs and respiratory tract. The spectrum of research spans from molecular and cell based investigation to bedside and population based studies. The Branch also provides clinical pulmonary physiologic testing, consultative and advanced bronchoscopic services and offers specialty research training of pulmonary and critical care clinical fellows.

Asthma and Lung Inflammation

Asthma affects approximately 8% of the U.S. population with significant associated morbidity and mortality.  Despite recent advances, there is an ongoing need to develop new treatments for severe asthmatics who do not respond to current therapies (Please see this video to learn more how asthma affects patients who are participating in clinical asthma research at NIH: https://www.youtube.com/watch?v=jVUZLcZwyxk).  To address this clinical problem, the Laboratory of Asthma and Lung Inflammation has identified novel roles for apolipoproteins and lipoprotein receptors in modifying airway inflammation, airway remodeling, and airway hyperreactivity in asthma.  Furthermore, by defining new mechanisms that modify asthma pathobiology, our laboratory has identified novel treatment approaches that are currently being advanced to clinical trials so that we can begin to assess their safety and effectiveness for asthma.

Chronic Airway Infection

The Laboratory of Chronic Airway Infection, led by Dr. Kenneth Olivier, focuses on bronchiectasis, a condition that damages the body's ability to clear mucus from the airways and increases risk of severe lung infections by nontuberculous mycobacteria (NTM), which commonly are found in wet environments such as streams, rivers, and marshes. People with inflammatory lung disease such as cystic fibrosis are particularly vulnerable to this condition. Dr. Olivier hopes to contribute to reducing the impact of such infections by studying common genetic characteristics of the people who suffer from them, defining how the infections lead to disease, and ultimately developing more effective, efficient treatments. Dr. Olivier and his collaborators also seek to address potential genetic risk loci that might explain overlapping characteristics of health conditions such as cystic fibrosis, primary ciliary dyskinesia, connective tissue disorders including Marfan or Ehlers-Danlos syndromes, and immune-related disorders.

Translational Research

The Laboratory of Translational Research, led by Dr. Joel Moss, focuses on clinical and translational areas of investigation. Primary clinical and translational studies address the pathogenesis and treatment of cystic lung diseases, such as lymphangioleiomyomatosis (LAM). Studies of LAM focus on the growth, genetics and metastasis, or spreading, of LAM cells, which is responsible for destruction of the lung parenchyma. Basic studies examine the post-translational modification of proteins by ADP-ribosylation, both that catalyzed by bacterial toxins involved in disease as well as the reversible ADP-ribosylation cycle endogenous to human cells, which participates in membrane repair and response to oxidative stress.
