Background

Dr. Neptune is a pulmonary, critical care physician with expertise in genetic disorders of the matrix with pulmonary manifestations. She is also skilled in the management of patients with advanced obstructive lung disease, especially emphysema. Dr. Neptune has extensive expertise in the diagnosis and management of the pulmonary complications of Marfan Syndrome, Loeys-Dietz Syndrome, vascular Ehlers Danlos Syndrome and other matrix disorders and serves on the Professional Advisory Board of the Marfan Foundation.  She is also an expert on tobacco dependence and is the Vice-Chair of the Tobacco Action Committee of the American Thoracic Society. 

Dr. Neptune earned her M.D. from Harvard Medical School. She completed her residency and performed a fellowship in pulmonary and critical care at the University of California, San Francisco. She also performed a fellowship in genetics at Johns Hopkins. 

Her research interests include therapeutic strategies in Marfan syndrome; mechanisms and prevention of progression of COPD; and hepatocyte growth factor signaling in airspace homeostasis. Dr. Neptune is committed to creating a diverse research community and clinical workforce. She is involved in multiple diversity initiatives at Johns Hopkins and the American Thoracic Society. She is also involved in increasing awareness of tobacco dependence and the needed regulatory policies.

Dr. Neptune serves on the Compliance Compensation Subcommittee for the Department of Medicine.

Research Summary

Dr. Neptune has a research focus on regenerative approaches to COPD-emphysema, mucus hypersecretion in COPD, genetic disorders of the matrix and health disparities in tobacco dependence.  She has been funded by the NIH, Marfan Foundation, March of Dimes, Maryland Stem Cell Research Foundation.    Her active research efforts include a detailed assessment of airway mucus properties that associate with COPD progression, the dissection of the role of TGF-b and angiotensin signaling in lung maintenance and repair, the identification of novel approaches to lung regeneration and the determination of the role of sleep apnea in Marfan aortic disease.   Her lab uses a combination of mouse and human reagents, novel genetically targeted animal models and primary lung resident cell based approaches.  Her long term goal is to provide therapeutic reagents that can reverse established emphysema in patients with acquired, congenital or genetic disorders.   Dr. Neptune is a standing member of the LIRR Study Section in the NHLBI, a member of the Board of Scientific Advisors at the NIH Clinical Center and the Program Committee Chair of the Respiratory Cell and Molecular Biology Assembly in the American Thoracic Society.
