Dr. David Munn’s current research focuses on tumor immunology and molecular mechanisms of immune suppression and tolerance.  Dr. Munn’s laboratory studies the regulation of T-cell activation by tolerogenic dendritic cells and regulatory T-cells (Tregs) in the setting of cancer.  A major focus of the laboratory is the immunoregulatory role of tryptophan metabolism via the enzyme indoleamine 2,3-dioxygenase (IDO).  Dr. Munn’s research is supported by grants from the National Cancer Institute and through charitable endowments for pediatric oncology research.

Active projects include multiple preclinical and basic-science studies in tumor immunology, enhancement of anti-tumor immune responses and control of regulatory T-cells.
