Asthma Research

Over the years, and as part of our broader commitment to research on lung diseases, the NHLBI has led and supported asthma research to discover better prevention and treatment options. Research supported by the NHLBI has also helped us understand what leads to and affects asthma, and it has provided doctors with information about what treatments work best for people who have asthma. 

NHLBI research that really made a difference

NHLBI research that really made a difference

For nearly 20 years, the NHLBI Severe Asthma Research Program (SARP) has transformed our knowledge of severe asthma. Research supported through the program has identified secondhand smoke, pneumonia, and obesity as key risk factors for asthma. Studies have also found genetic variations linked with severe asthma and biomarkers for asthma severity. Researchers can request access to the data on dbGaP.

Research funded by the NHLBI

Research funded by the NHLBI

Our Division of Lung Diseases and its Airway Biology and Disease Branch oversee much of the research on asthma we fund. The Asthma Program supports research related to asthma, including the role of inflammation in the development of asthma, genetics and asthma, and clinical management of asthma in adults and children.

RESEARCH FEATURE

Learn about one PrecISE study that is looking at treatments that may help support people with severe asthma or asthma that hasn’t responded to traditional treatments: Personalizing treatment for severe asthma.

Current research on asthma biology

The different bacteria in a person’s body can affect the immune system. We support studies to figure out whether different bacteria play a role in developing certain types of asthma.

  • NHLBI-funded research will look at how genes are regulated in airway epithelial cells to better understand how they affect the development of asthma. Epithelial cells line the lung’s airways. As researchers learn more about how changes in the cells lead to asthma, they hope to develop treatments to reprogram the epithelium and prevent or cure asthma and other lung diseases.
  • An AsthmaNet study found different bacteria in the airways of people with asthma compared to those without asthma. Some of the observed differences could help predict the response to inhaled steroids. Researchers can request the data through our Biologic Specimen and Data Repository Information Coordinating Center.
  • NHLBI-supported researchers are developing new and personalized approaches to treating severe asthma. The study builds on earlier research which led the researchers’ discovery of three mechanisms that are relevant to severe asthma.

Current research on asthma disparities

African Americans are more likely to develop asthma and three times more likely to die from asthma-related causes than white Americans. Research on this topic is part our broader commitment to addressing health disparities and inequities

Asthma research labs at the NHLBI

Asthma research labs at the NHLBI

The Laboratory of Asthma and Lung Inflammation, located within the Pulmonary Branch, is focused on developing new treatment approaches for people with severe asthma. Headed by Stewart J. Levine, M.D., the lab’s researchers found a new biological pathway that leads to asthma. They continue to study this pathway, as well as an important molecule in it called apolipoprotein E (ApoE).

  • The NAEPP’s Expert Panel Report 4 (EPR-4) Working Group was established in 2018 to update the 2007 Guidelines for the Diagnosis and Management of Asthma (EPR-3) in focused topic areas. The working group members reviewed the latest research to update the guidelines on treatments and management of asthma, including the role of immunotherapy, the effectiveness of indoor allergen reduction, and the use of fractional exhaled nitric oxide (FeNO).

  • Learn More Breathe Better® is a national health education program for asthma, COPD, and other lung and respiratory diseases. The program raises awareness about asthma and other lung conditions and supports the promotion, implementation, and adoption of evidence-based care. Learn More Breathe Better® Asthma offers a series of asthma handouts to patients and caregivers, including tips for talking to your doctor. 
  • Since 1989, the National Asthma Education and Prevention Program (NAEPP) has worked with medical associations, voluntary health organizations, and community programs to educate patients, healthcare professionals, and the public about asthma.
  • The Lung Tissue Research Consortium (LTRC) provides human lung tissues to qualified investigators for use in their research. The program enrolls patients who are planning to have lung surgery, collects blood and other clinical data from these donors, and stores donated tissue that otherwise would be discarded after the lung surgery. The LTRC provides tissue samples and data at no cost to approved investigators.
