| Research Abstract |
Alpha-glucans such as starch and glycogen are abundant in the human oral cavity. Degradation of alpha-glucans by alpha-glucanotransferase (CGTase) enzymes leads to the clodextrins (CDs) production. CDs induce a cholesterol-depleted membrane and a destabilization of the barrier function of tight junctions in host cells. We demonstrated that Porphyromonas gingivalis, a periodontal pathogen, utilizes alpha-glucans to produce CDs. Our data suggest that P. gingivalis-produced CDs contribute to the pathogenesis of oral bacteria-associated systemic illness.
