Brief Bio

Dr. O'Reilly completed this medical degree at the Royal College of Surgeons in Ireland (1986-1992).  His internship and residency were accomplished in Dublin teaching hospitals (1992-1995) and at Boston University (1996-1998), followed by a fellowship in pulmonary and critical care medicine at the University of Alabama at Birmingham (1998-2001).  Dr. O'Reilly has a longstanding interest in basic and translational research in the lung.  During his fellowship, he worked in the laboratory of Professor Sadis Matalon in the UAB Dept. of Anesthesiology Research, studying innate immunity and acute lung injury.  He has been a co-investigator in the NIH COPD clinical research network since 2002.  In 2005, Dr. O'Reilly began work in the laboratory of Professor J Edwin Blalock, studying the role of matrix fragments in neutrophilic airway inflammation, with a particular emphasis on COPD.  Dr. O'Reilly is a co-investigator on several NIH grants and was recently awarded a career development award (K08) by the National Institutes of Health.

Clinical Interests 
COPD

Academic & Research Interests

Dr. O'Reilly says, "My work in Dr. Blalock's laboratory centers on the collagen degradation fragment, proline-glycine (PGP).  PGP is produced in the lung by the action of proteases on collagen during inflammation.  PGP is also a neutrophil chemoattractant due to a structural homology with CXC chemokines and may therefore aggravate airway inflammation in disease such  COPD and cystic  fibrosis.  My interest lies in clarifying PGP's role as a biomarker or predictor for COPD and as a potential therapeutic target using specific PGP inhibitors that we have generated.   Much of my current research consists of measuring PGP in sputum and serum samples from COPD patients and healthy individuals using mass spectrometry, and correlating PGP with clinical features of disease.  We are also interested in the enzymes that generate PGP and have identified a novel role for prolyl endopeptidase (PE), a post-proline cleaving enzyme, as the critical enzyme for cleaving PGP from collagen in inflammation.  We are currently measuring PE in clinical samples using activity assays and antibodies that we have generated.  In other studies, we are investigating the role of PGP and PE in a smoking mouse model of COPD. We believe that PGP and PE may have the potential to provide novel therapies for COPD that target airway inflammation and may predict those smokers who will develop COPD many years in advance of clinical disease.
