Research Themes: Host-Pathogen Systems Biology,Periodontal Infections, Chronic Systemic Inflammation, and Alzheimer’s Disease

A complex community of Gram-negative bacteria, known as periodontal pathogens, has significant potential to induce gum inflammation and various inflammatory diseases. We examine the structure and role of key immunostimulants, immunomodulating factors, and signaling components produced by periodontal pathogens in regulating innate immune responses at molecular and cellular levels. The goal of our studies is to advance the identification of key contributors to the development and sustainability of inflammatory conditions, diagnostic biomarkers, and druggable targets.

Our research is interdisciplinary and requires leveraging innovative system-based approaches while integrating tools from molecular/cellular biology, biochemistry, microbiology, immunology, and bioengineering.

Our current projects focus on

  • Investigating the structural variation of lipopolysaccharide (LPS; endotoxin) in periodontal pathogens and its contribution to inflammatory responses underlying periodontal inflammation and Alzheimer’s disease.
  • Studying key signaling systems that control the virulence potential of periodontal pathogens and impact innate immune responses.
  • Understanding fundamental molecular interactive networks and cellular reprogramming in the host-pathogen system, promoting self-sustained, chronic inflammatory conditions.
  • Leveraging molecular engineering for deciphering and imaging the intricate molecular and cellular interactions implicated in inflammatory conditions.
