Molecular characterization of the gingipains of Porphyromonas gingivalis

Abstract

Chronic periodontitis is a bacteria-associated inflammatory disease of the supporting tissues of the teeth, which results in the destruction of tooth support and ultimately leads to tooth loss. The disease is a major public health problem with a large economic burden and has been associated with an increased risk of cardiovascular disease and pre-term birth and low birth weight. The bacterium Porphyromonas gingivalis has now been identified as a major pathogen in the development of chronic periodontitis. We have identified a major virulence factor of P. gingivalis which is an extracellular complex of proteins involved in binding and destroying host proteins. The aim of this proposal is to ch..
