I am currently working on functional T and B cell studies in understanding the immunological basis of cholera infections in Bangladesh and related to protection. My main research interests focus on characterization of antigen specific single cells in blood and mucosa to better understand cholera pathology by using cutting edge research nanotechnology and flow cytometry.
My ¬†major ¬†interest ¬†in ¬†the ¬†last ¬†few ¬†years ¬†has ¬†been ¬†made ¬†in ¬†microbiology ¬†and immunology ¬†of ¬†infectious ¬†diseases ¬†in ¬†developing ¬†countries ¬†especially ¬†to ¬†enteric infections, ¬†eg. Vibrio ¬†cholerae, ¬†enterotoxigenic Escherichia ¬†coli, and Helicobacter pylori. ¬†I ¬†am ¬†currently ¬†working ¬†on ¬†functional ¬†T ¬†cell ¬†studies ¬†in ¬†understanding ¬†the immunological basis of different enteric infections in Bangladesh and protection. ¬†
My ¬†research ¬†is ¬†focuses ¬†on ¬†for ¬†understanding ¬†of ¬†cellular and ¬†adaptive ¬†immunity ¬†in children as well as in adults. The major goal of these studies is to ¬† ¬† ¬† understand the T-B cell interaction, and the type of T cells that are mainly responsible for B cell help. ¬†
I ¬†am ¬†also ¬†involved ¬†with ¬†cholera ¬†(Shanchol) ¬†vaccine ¬†clinical trial, ¬†where ¬†we ¬†are evaluating ¬†humoral ¬†and ¬†adaptive ¬†immune ¬†responses ¬†in ¬†different ¬†age ¬†groups ¬†of participants of Bangladesh.
- We have particular interest to study mucosal and systemic immune responses to enterotoxigenic Escherchia coli infection and relation to protection, that includes evaluating if ETEC diarrhea induces antigen specific acute B and T cell responses as well as memory responses which are long lasting.
- Another important area has been made is in the development of diagnostic tests for detection of H. pylori antigens. As the incidence of H. pylori infection is very high in these endemic settings, this has been extremely important to diagnose this infection in children and adults. In addition, we are also evaluating the immune responses in developing countries and how much this is differing from developed countries. ¬†
