The primary focus of my group is the study of mechanisms that allow neutrophils (an important type of white blood cell) to respond to bacterial infections in the lung. Specifically, we have focused on a series of chemical reactions that trigger the cell's response following detection of a foreign presence in the lung or bloodstream. The inflammatory response of the neutrophils is central to both protection of the lung from diseases like bacterial pneumonia, as well as injury to the lung in diseases like cystic fibrosis. By defining the series of events that occurs prior to responses by the neutrophil, we may be able to enhance beneficial functions of the neutrophil in diseases (such as killing bacteria), and block the harmful effects of too much inflammation in diseases like septic shock, interstitial lung disease, and cystic fibrosis.

Pro-Inflammatory Stimulation and Intracellular Signaling Pathways in the Human Neutrophil
Chris Gregory, M.D.
Many pulmonary diseases are characterized by a massive accumulation of neutrophils in the airspaces. The recruitment of neutrophils to the lung is a central part of the innate host defense against infection. However, in certain conditions, such as the Acute Respiratory Distress Syndrome (ARDS) and Cystic Fibrosis, it appears that the actions of the neutrophils are injurious to the airways. Other infections, such as those caused by mycobacteria, appear to evoke very little neutrophil response. Over the past decade, intensive efforts have been focused at inhibiting neutrophil responses that appear to be "overexuberant" in diseases that feature intense inflammation.
External stimulation and subsequent functional responses of eukaryote cells are linked through a series of intracellular phosphorylation events that form signal transduction pathways. In the neutrophil, pro-inflammatory stimuli selectively evoke a range of common and unique functional responses. We have studied in depth the p38 mitogen-activated protein kinase (MAPK) pathway that is utilized by human neutrophils in response to a wide range of clinically important pro-inflammatory stimuli. We have found that a broad spectrum of neturophil responses are mediated by p38 MAPK, and that this signaling mechanism can serve both as a regulator of cell response and a marker of cellular activation. With newly available inhibitors, which selectively block the activation of p38 MAPK, this molecule represents a potential target for development of anti-inflammatory agents.
A second focus of our group is to study the coordination of neutrophil responses. From the first seconds of stimulation to the ultimate death of the cell, the neutrophil undergoes a series of responses that can either be “pre-programmed” or “selective”. Responses include neutrophil adhesion, chemotaxis, release of oxygen radicals, release of preformed granule proteins, transcription of RNA, de novo synthesis of proteins, phagocytosis, and ultimately necrosis or apoptosis of the cells. Although much is known about each of these responses, very little is known of how these responses are coordinated. Through a combined functional, signaling, and genomic analysis, we are examining the coordinated response of the neutrophil to LPS in the setting of acute lung injury, and the response of the neutrophil to Pseudomonas aeruginosa in the setting of Cystic Fibrosis lung disease. In addition, we are examining the response of the Pseudomonas to the neutrophil, in the context of bacterial survival and biofilm development. Through these analyses, we can now identify features of the neutrophil response characteristic of these diseases, and test the relative effect of various promising anti-inflammatory agents.
