PJ Maglione, MD, PhD is a physician-scientist in the Pulmonary Center of Boston University School of Medicine. His research efforts in the areas of primary antibody deficiency and B cell biology have been supported by numerous sources including the Thrasher Research Fund, Clinical Immunology Society, Primary Immune Deficiency Treatment Consortium, American Association of Allergy, Asthma and Immunology, and the National Institutes of Health. Dr. Maglione studies human B cell biology, particularly in how it relates to and is informed by primary immunodeficiency disorders. His research program utilizes high throughput strategies such as RNA sequencing, B cell receptor repertoire analysis, and seromics together with cell culture, immunofluorescence, and information from the patient medical record to conduct bedside-to-bench studies on immunodeficiency disorders.

In addition to running a research laboratory, Dr. Maglione provides clinical care for patients with immunodeficiency disorders and has particular interest and expertise in common variable immunodeficiency (CVID) and its related complications, including chronic lung disease. His publications include identification of novel biomarkers and treatment of CVID interstitial lung disease.
