Loma Linda University Electronic Theses, Dissertations & Projects
The expression of extracellular proteolytic activities is highly regulated in both prokaryotic and eukaryotic systems. This regulation can occur at multiple levels including expression of the protease genes, secretion, processing of an inactive secreted precursor to its active form and/or the posttranslational glycosylation of the proteins. These regulatory mechanisms are vital to ensure that expression is tightly controlled. Porphyromonas gingivalis has been associated with adult periodontitis and in the development of many systematic diseases. The major virulence factors of P. gingivalis, the gingipains, are responsible for pathogenesis including degradation of complement and immunoglobulin, inactivation of cytokines and their receptors, …
