Dr. Kao’s research program focused on understanding the role of gut microbes in chronic inflammatory disorders with an emphasis on the homeostatic mechanisms of host–microbe interaction in the gastrointestinal tract. Current studies in this laboratory use genetically engineered and experimental mouse models to investigate several epithelial and immune pathways critical for maintaining mucosal homeostasis. Current projects funded by DoD/VA and NIH include probing the pathways involved in the development of Helicobacter-associated intestinal metaplasia and the role of epithelial NADPH oxidases, Duox2, in preventing gut bacterial translocation. Understanding these pathways may lead to new therapeutic strategies and targets for the prevention of bacterial-driven gut inflammation and its associated malignant complications.
