My primary research interest includes in the area of immunology, mucosal inflammation,
chemokines, immunotherapy and complimentary and alternative medicine. Inflammatory
bowel disease (IBD) is a gastrointestinal disease of chronic inflammatory condition
and the causes of human IBD remain unknown. We have shown that anti-CXCL10 Ab treatment
abrogates spontaneous colitis. Currently, I am working on to understand the steps
during CXCL10 mediated cellular and molecular mechanism of IBD abrogation and host
immune response during the progression of IBD. This will help to better understand
the pathogenesis of IBD and other inflammatory conditions. This work will contribute
to a better understanding of autoimmune disease pathogenesis and the development of
vaccines for inflammation therapeutics in general.
Currently, I am working on intervention and prevention strategies against interstitial cystitis (IC), which is a chronic, relapsing and severely debilitating disease of the urinary bladder. Compounding these problems is the lack of blood or urine tests and consistently effective treatments for IC. We show the increase in CXCR3 ligands in the serum of IC patient as compare to normal healthy donors. We show for the first time that, CXCL10, CXCL9, and CXCL11 are significantly up regulated both systemic as well mucosal in IC patients, compared to normal healthy donors. These studies have important implications for the design, assessment, and implementation of effective IC diagnosis, intervention and prevention strategies.
I am also working on another project to examine the effects of resveratrol on experimental murine model of colitis. We have shown that resveratrol protects against chronic and dextran sodium sulphate (DSS) induced colitis by inducing myeloid derived suppressor cells (MDSCs), down regulating mucosal and systemic effectors and CD4+T cells that express CXCR3+ expression. I wish to continue my work in the field of mucosal immunology, inflammation using alternative medicine as effective treatment for various autoimmune diseases and inflammation in general.
