Summary
In this study we will characterize a novel bacterial secretion system that we have discovered. This system mediates the secretion of proteins from the bacterial cell and their attachment to the cell surface. This system is essential for the virulence of a bacterium associated with severe gum disease. The chacterization of this system may offer opportunities for the development of new treatments to target this disease.

Summary
Porphyromonas gingivalis is a keystone pathogen in chronic periodontitis. This bacterium exists as part of a biofilm on the surface of the tooth and selectively packages enzymes, toxins and antigens on to vesicles that penetrate host tissue and cause the inflammatory response that is associated with disease progression. In this study we will determine the host response to vesicles and determine the role of a specific protein in vesicle biogenesis.

Summary
We have discovered an innovative biochemical strategy whereby our novel compounds exploit and trick a part of the detoxification machinery, that is the transporter, P-glycoprotein, to specifically kill drug resistant cancer cells. Herein, we take advantage of this biochemical mechanism to design novel and safe drugs to selectively target resistant tumours.
