Focus Areas

Our nationally and internationally recognized researchers have interests that span the full spectrum of pulmonary diseases. The following are particular areas of emphasis:

Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) remains one of the major causes of death and disability in the United States and globally. The UNC Pulmonary Division includes leading researchers investigating determinative factors in COPD development, disease progression and treatment. Investigators from the Marsico Lung Institute are defining key aspects of COPD biology including the role of the airway surface liquids and airway epithelial cells in COPD pathogenesis as well as inflammatory and innate immune processes underlying cigarette-smoke induced lung disease. UNC is the collaborative studies coordinating center for the Subpopulations and Intermediate Outcome Measures In COPD Study (SPIROMICS), one of the largest prospective studies evaluating phenotypic, biomarker, genetic, genomic, and clinical data from patients living with COPD. Our clinical investigators conduct translational and pharmacologic studies focused on understanding mechanisms of COPD phenotypes in both exposure and genetic (alpha-1 antitrypsin deficiency) COPD as well as new drug treatments. Pulmonary investigators also collaborate closely with colleagues in UNC’s Division of Infectious Diseases, UNC’s Gillings School of Public Health and the UNC Center for Environmental Medicine, Asthma and Lung Biology to study COPD epidemiology, mechanisms and treatment.

Cystic Fibrosis

The UNC CF Center is a recognized leader in the science of cystic fibrosis, with activities that span from basic laboratory to patient-oriented. The Marsico Lung Institute (hyper link here to Marsico website) is the academic home for a large number of researchers who are focused on the basic causes and treatment of CF lung and gut disease. Patient-oriented research is also a high priority at the UNC CF Center. We conduct single center studies that address important topics, such as the development of new tests that are designed to speed up drug development and help us learn more about CF lung disease in patients. We also participate, and often lead, multicenter clinical trials of new CF therapies. In this era of rapidly advancing CF therapeutics, teamwork is critical. Patients with CF are the center of this team – and we strive to involve as many patients as possible in studies that will move new therapies closer to approval for all CF patients.

Lung Immunology

The Division includes investigators interested in basic and translational immunology of lung diseases, particularly the innate immune responses that underlie many lung diseases. Research programs focus on the immunological processes and molecular mechanisms underlying lung injury and repair. Studies investigate the immune cell types and their responses in patients with lung disease. Research interests within the Division focus on how the immune cells function throughout lung disease.  For example, studies examine how immune cells response early during an infectious process and how immune cells interact with other cell types to promote lung repair. In addition to basic mechanistic studies, ongoing translational research and clinical trials investigate the pathogenesis of lung injury and repair to improve treatments for patients with lung disease.
