Professor Owen Patrick Smith

Medical School (Paediatrics)


Regius Professor of Physic (1637) (Molecular Medicine Ireland)

My main area of ongoing research for the past number of years has been elucidating the relationship (at the molecular and cellular level) between the protein C (PC) activation pathway and the systemic inflammatory response sepsis syndromes. To date, the research group has made significant clinical and scientific contributions to the emergence of a new paradigm regarding the patho-biology of severe sepsis / septic shock and we believe that this work has been instrumental in establishing APC/PC replacement therapy in this catastrophic disease, as all other novel therapeutic interventions in these patients have failed. This work has been carried out wholly in Ireland and has been supported in part by the Health Research Board of Ireland and Children's Medical & Research Foundation. The research programme has generated numerous PhD, MD and MSc studentships and peer reviewed publications in the Lancet, Blood, Thrombosis and Haemostasis and the British Journal of Haematology.
