Chief, Clinical Pathophysiology Section, LHDDirector, Clinical Center, National Institutes of Health (NIH)
The mission of the Clinical Pathophysiology Section is to study the genetic causes and the biological consequences of inborn diseases of phagocytic blood cells.
Chronic granulomatous disease (CGD) has been our major focus. CGD occurs in patients whose phagocytes (neutrophils and monocytes) are unable to generate antimicrobial levels of reactive oxygen species (e.g., superoxide anion) due to mutations in components of the NADPH oxidase as shown below.
Without sufficient production of superoxide anion, a key mediator of host defense, these patients suffer from life-threatening bacterial and fungal infections as well as tissue granuloma formation and other inflammatory diseases. Our section studies host and microbial determinants of pathogenesis by fungal (e.g., Aspergillus fumigatus) and bacterial (e.g., Granulibacter bethesdensis) causes of infection in CGD patients.
Genetic immunodeficiencies such as CGD also provide unique opportunities to study the roles of specific elements of the immune system in the pathogenesis of inflammatory diseases in human subjects. For example, one of our currently active clinical studies uses non-invasive radiologic methodology to evaluate the contribution of reactive oxygen species to the pathogenesis of cardiovascular disease. Another active component of our clinical program is the use of experimentally induced blisters to study the dynamic process of acute inflammation in human subjects.
Dr. Gallin received his medical training at Cornell University Medical College in New York City followed by residency in internal medicine at Bellevue Hospital. In 1971, he first came to NIH as a clinical associate in Sheldon Wolff’s Laboratory of Clinical Investigation. In 1974 he served as senior chief resident in medicine at Bellevue Hospital before returning to NIH in 1976 as a senior investigator. Dr. Gallin has served as director of the NIAID intramural research program (1985–1994) and as chief of the Laboratory of Host Defenses (1991–2003). Since 1994, Dr. Gallin has also been director of the NIH Clinical Center. Among his honors are membership in the American Society of Clinical Investigation, the Association of America Physicians, and the Institute of Medicine of the National Academy of Sciences and a master of the American College of Physicians.
Closely associated with CPS is the Neutrophil Monitoring Laboratory (NML), a CLIA-certified facility in Frederick, Maryland, that supports the clinical and basic research of the NIAID Laboratory of Host Defenses and the NIAID Laboratory of Clinical Infectious Diseases. NML is headed by Douglas Kuhns, Ph.D. (contractor, Leidos Biomedical Research, Inc.), and performs genetic and functional studies on cells isolated from patients with recurrent bacterial and fungal infections, as well as patients with abnormal inflammatory responses.
