Research Interest:

Integration of nutritional therapy with innate and adaptive immunity in infectious disease model

Summary of Research:

My research interest has been emergent to develop translational disease intervention strategies against important human chronic diseases by cultivating the balance between tolerance versus immunity, abrogating inflammation, mediated by gut microbiome.

Microbiome based nutritional therapy: A new arsenal against Toxoplasma gondii treatment induced obesity

The project based on the disruption of synchrony between gut microbiome and metabolic rhythms by Toxoplasma gondii infection. We ask the question, how does altered microbiome population develop obesity due to metabolic dysfunction in course of treatment of chronic T. gondii infection. Competition between symbionts vs pathobiont determines tolerance (Treg/Tr1/Breg/Br1) vs inflammation  (Th1/Th17/Inflammatory B1). Chronic infection leads to uncontrolled inflammation towards obesity. This translational research will examine mechanisms of the beneficial effects of probiotics, and will discover microbiome based new generation of anti-inflammatory small molecules against T. gondii induced obesity.
