Research Interest:

Although inflammation is essential for the body to protect itself against infection, when the process becomes overly aggressive it contributes to a host of inflammatory conditions including inflammatory bowel diseases, heart disease, autoimmune disorders, and sepsis. The laboratory studies the molecular mechanisms by which blood phagocytes such as macrophages and dendritic cells recognize microbial pathogens and initiate inflammatory responses.

The Underhill laboratory is focused on understanding basic mechanisms of innate immunity and control of inflammation during disease. The lab has been particularly focused on the role of phagocytosis in macrophages and dendritic cells in modulating inflammatory signaling, making important contributions to defining Toll-like receptor ligands, characterizing Toll-like receptor signaling pathways, characterizing C-type lectin signaling pathways and in defining the role of microbial degradation in triggering innate immune responses including inflammasome activation. Recently, the laboratory has described the presence of fungi in the microbiome of the gut and is actively engaged in understanding the biology of this ”mycobiome” and how it interacts with the immune system and contributes to health and disease.
