1) Host response to infection and (2) regulation of inflammatory diseases. The primary function of the immune response is to protect the host from harmful microbial invaders. The initial response of the host to microbial infection is to mobilize and recruit innate phagocytic cells (neutrophils and macrophages) to the site of infection where they will engulf and kill the invaders. If required, other more specialized immune cells (T calls and B cells) can be activated to join in the fight. Pathogenic microbes are able to thwart the immune response (at least for a while) and thus cause disease. Understanding the mechanisms used by the host immune response to remove pathogenic microbes, and those used by the microbes to combat this removal, is a primary focus of the lab.
Many of the diseases of the modern world (arthritis, heart disease, cancer, asthma, etc) are considered by many researchers to be caused by chronic inflammation. Inflammation is in general a beneficial response. It occurs in response injury or infection, mediates removal of microbes or irritants, and restores the tissue to its normal function. However, sometimes this process goes awry and the tissue fails to undergo resolution of the inflammation and chronic inflammatory disease ensues. In the past, resolution of inflammation was thought to be a passive event, the irritant was removed and the inflammation just “went away”. Now we know the resolution of inflammation, just like its development, is a tightly controlled process. However, little is known about how the resolution of inflammation is regulated. Bioactive lipids (eicosanoids) are known to be important regulators of inflammatory processes. How these compounds regulate both the development and resolution of inflammation is another primary focus of the lab.
