 Overview My lab is interested in understanding the three-way crosstalk and interactions between gastro-intestinal epithelial cells, immune cells and microbe (beneficial as well as pathogenic). The host gut barrier is disrupted after encountering microbes/toxin/ microbial products linked to inflammation and chronic diseases. Inflammation following infection also leads to DNA damage, which predisposes the epithelium to neoplastic transformation and cancer progression. Our recently developed gut organoid/Gut-on-a-chip model with epithelial cells, immune cells and microbes will be utilized to investigate mechanisms for gastro-intestinal inflammatory diseases, both oncogenic and non-oncogenic. The model will be useful for the identification of new diagnostic and therapeutic targets, identification of beneficial vs harmful microbes and nutritional components and to screen efficacy of novel barrier-protective drugs to combat inflammation-linked diseases. The core expertise of the lab are biochemistry, molecular biology, cell biology, microbial pathogenesis and mucosal immunology.
