Dr. Santasabuj Das

Dr. Santasabuj Das

Dr Santasabuj Das is currently appointed as Scientist E at the National Institute of Cholera and Enteric Diseases (NICED), Kolkata. He is also the principal investigator and coordinator of the Biomedical Informatics Center of ICMR at NICED. He has the academic and professional background in Clinical Medicine and is pursuing a full-time research career since 1998. He joined NICED as an independent investigator and a permanent employee in January 2005. His current research interest spans several areas of host responses to microorganisms (both pathogens and commensals) including immune responses and vaccine development. The major focus of his research is the pathogenesis of human Salmonella infections, development of subunit and conjugate vaccines against Salmonella Typhi and Paratyphi and the regulation of mucosal immune responses at the intestine during homeostasis as well as under disease conditions, such as intestinal infections and inflammatory bowel diseases. Dr Das extensively uses computational tools, in vitro and in vivo techniques and clinical materials to address his research questions. His laboratory has developed a novel mouse model of Salmonella Typhi infection. Using this model, his research has identified several virulence factors critical for the pathogenesis of Salmonella Typhi and developed a candidate subunit vaccine. His research has unearthed a number of novel signalling mechanisms that underlie pro-apoptotic and anti-cancer role of dietary fibres and regulate intestinal innate immune responses by regulating the expression of Toll-like receptors and small cationic antimicrobial peptides. His research has been funded by extramural grants from all the major funding agencies of the country (ICMR, DBT, CSIR, DST, DHR) as well as the Ministry of Education, Culture, Sports, Science and Technology of Japan and Japan Agency for Medical Research and Development. Dr Das has published 43 original research articles and 3 review articles in reputed international journals, 2 book-chapters and one WHO Module. His innovative research has been granted 2 international and one national patents. In recognition of his seminal contribution to the biomedical and health science research, he has been awarded the National Bioscience Award for Career Development, 2011 by the Department of Biotechnology, Government of India and Fulbright-Nehru Senior Research Fellowship, 2012. He is also an elected member of the West Bengal Academy of Science and Technology.

Profile

Research Experience

After receiving the postgraduate medical degree, Dr Das worked as a Senior Resident at the Department of Clinical Immunology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow. He joined National Center for Biological Sciences (NCBS), Bangalore as a Visiting Postdoctoral Fellow in 1998 and continued to work there on signal transduction mechanisms of cervical cancer till early 2000. He pursued further postdoctoral research at Thomas Jefferson University, Philadelphia, Pennsylvania, USA and worked on the transcriptional regulation of MHC Class II genes. He then moved to Tufts University Medical Center at Boston, Massachusetts, USA and focused his research on the exploration of the role of Tpl2, an upstream mitogen-activated protein kinase in transducing pro-inflammatory signals and in lung and pancreatic inflammation. He completed his postdoctoral training in early 2005 and returned to India to join NICED, Kolkata. In this institute, he has used computational as well as in vitro and in vivo techniques to study host-pathogen interactions in the mucosal and systemic compartments and is aiming to develop novel therapeutics against enteric bacterial infections.

Research Interests

Two major areas of Dr Das's research include host-pathogen interactions and vaccine development for Salmonella Typhiand Paratyphi infections, and the regulation of mucosal immune responses at the intestine in health and disease. His laboratory has developed a novel mouse model of oral Salmonella Typhi infection that helped to identify several virulence factors critical for epithelial invasion and phagosomal survival ofSalmonella. Dr Das's research has unearthed a number of novel signalling mechanisms that underlie pro-apoptotic and anti-cancer role of dietary fibres and shape intestinal innate immune responses by regulating the expression of Toll-like receptors and small cationic antimicrobial peptides (CAMP). He is also studying CAMP-based antimicrobial therapy, both by stimulating the release of endogenous peptides and through designing synthetic peptides.
