| Research Abstract |
We analyzed microbicidal molecular basis against intercellular pathogens in periodontal cells in order to evaluate host susceptibility to periodontitis for future predictive dentistry.
Following the entry to gingival epithelial cells, P. gingivalis is sorted to early endosomes, and the half of the intracellular pathogens are transported to recycling pathway via SNARE protein, VAMP2, which allows the bacterial exit to the extracellular circumstances. While, remaining half are sorted to autophagosome. The machinery is found to be formed in contact sites between endoplasmic reticulum and mitochondria, which is a very unique finding indicating that 2 different organelle make a concerted effort to the formation of another organelle.
