Research Interests:

Oral bacterial-induced host immune responses are a key to the initiation and progression of both periodontal diseases and some systemic diseases including atherosclerosis, diabetes, arthritis, low birth weight, obesity and cancer. Such responses can be protective by controlling the bacteria challenge, or destructive through prolonged or excessive production of endogenous mediators of inflammation and tissue remodeling. My research focus is on the signal transduction pathways that regulate the magnitude and nature of the host immune response and identify the potential targets for intervention. Inhibition or interference with these pathways is a potential avenue to ameliorate the severity of inflammatory diseases and aid in the development of novel and innovative immunotherapeutics.

 

There are two central foci:

(1) How do oral pathogens, such as P. gingivalis, activate phosphoinositide 3-kinase (PI3K) signaling and, thus, modify inflammation?

(2) What mechanisms are responsible for inflammatory regulation by PI3K and related signal molecules?

 

Currently, we are investigating the regulatory roles of serine/theronine and tyrosine protein kinases related to PI3K signaling pathway, such as Janus kinases (JAKs), glycogen synthase kinase-3 (GSK3), serum glucocorticoid-induced kinase-1(SGK1), and Forkhead box O1 (FoxO1), in P. gingivalis-mediated inflammatory immune responses. We are assessing the feasibility of these signaling molecules as potential anti-inflammatory therapeutic targets in vivo.
