Research Interests

Research interests: Dr. Dinauer studies the superoxide-generating leukocyte NADPH oxidase. Inactivating mutations in this enzyme result in chronic granulomatous disease (CGD), a primary immunodeficiency associated with recurrent bacterial and fungal infections as well as a variety of chronic inflammatory disorders, including inflammatory bowel disease and discoid lupus. These symptoms reflect the dual importance of the NADPH oxidase both for microbial killing and for negatively regulating cellular processes that limit inflammation by redox mechanisms. Moreover, hypomorphic NADPH oxidase gene variants are now linked to inflammatory bowel disease and autoimmunity.

Research interests are focused on the role of leukocyte oxidant production in the response to microbial pathogens, sterile inflammation, and predisposition to autoimmunity. Experimental approaches involve a combination of molecular and cell biology assays on human and mouse cells and use of mouse models, including recently developed mice lacking the NADPH oxidase in specific blood cell lineages. Current areas of study are a) host response to Aspergillus fumigatus, an opportunistic pathogen that is a major pathogen in CGD, likely reflecting both impaired fungicidal activity and excessive inflammation b) NADPH oxidase regulation of sterile inflammation and removal of apoptotic cells and c) synergy of NADPH oxidase deficiency with other lupus pre-disposing genes.
