Outline of Final Research Achievements

Nonalcoholic steatohepatitis (NASH) is an important cause of chronic liver injury in many countries. The incidence of NAFLD is rising rapidly because of the currently ongoing epidemics of obesity and type 2 diabetes. Bacterial endotoxin, such as lipopolysaccharide (LPS), is known to play a key role in the pathogenesis of NASH. In this project, LPS from p. gingivalis stimulation results in innate immune responses through TLR2 and 4 and elevated ALT in high-fat diet-induced steatosis mice. Furthermore, the STAT3-NFkB are thought to be the important receptor that case liver damage by LPS from p. gingivalis. Clinically, there are significant relation between the incidence of more than 10 lacations of periodontitis (deepest probing depth > 4mm) and the detection frequency of P. gingivalis in NASH patients.
