Host-pathogen interaction- Porphyromonas gingivalis mediated infection of the host cell

Porphyromonas gingivalis is an anaerobic gram-negative bacterium and a major causative factor for periodontal disease in humans. The cysteine proteases of P. gingivalis called gingipains function in bacterial survival, colonization and evasion of the host defenses. Although gingipains can cleave numerous substrates within the host cell, the exact functional consequence of this activity is not well understood. I am studying the mechanisms by which P. gingivalis and these secreted virulence factors enter the host cells and investigating their role in evasion of the intracellular innate immune signaling.
