Dr. Potempa earned his Ph.D. and D.Sc. (habilitation) in Biochemistry in 1982 and 1993, respectively, from Jagiellonian University, Krakow, Poland.  In 1985-1988 he conducted postdoctoral research at the University of Georgia and from 1989 to 2008, he worked there as a Senior Research Scientist.  From January 2009, Dr. Potempa was recruited to the University of Louisville Dental School as a Professor and Academic Scholar.  Simultaneously, Dr. Potempa maintained his teaching and research position at the Jagiellonian University since 1983, where he was head of Department of Microbiology since 2001 and promoted to Research Professor in 2005.  His current scientific interest revolves around proteolytic events in the pathogenicity of infectious diseases.  Dr. Potempa’s research achievements are highly recognized internationally as indicated by more than 9,900 citations of his publications (h-index:54).  Of note, for a decade (1995-2005) he was the second most cited scientist in Poland.

Research Interests and Current Projects: (brief description):

Dr. Potempa’s investigations are focused on proteolytic enzymes of bacterial pathogens that play important roles in the deregulation of a number of physiological pathways and evasion of host immunity.  Specifically, studies in Dr. Potempa’s laboratories concentrate on proteolytic systems of bacteria, including predominantly staphylococci and periodontal pathogens.  He discovered new families of proteinase inhibitors and proteinases, referred to as staphostatins and gingipains, respectively.  Furthermore, he found out that Porphyromonas gingivalis-derived gingipains could not only activate coagulation, fibrinolysis, and kinin pathways and signal through protease activated receptors in an unrestricted manner, but also deregulate host proteinase inhibitors through specific cleavage within their reactive site loops, thereby allowing for the additional involvement of host proteinases in the disease process.  Dr. Potempa’s current research has expanded to enzymes from Prevotella intermedia and Tannerella forsythia.  In addition to the pathophysiological significance of establishing new traits in microbial pathogenesis, these studies have led to discovery of unique proteinases in these two species of bacteria.  Dr. Potempa’s other interests are focused on bacterial pathogens interaction with the innate immunity system, a mechanistic link between periodontitis and rheumatoid arthritis, the characterization of new enzymes and elucidation of a novel protein secretion system (PerioGate) used by periodontopathogens to secrete their virulence factors.
