Sergey Seregin, PhD

Research Fellow, Internal Medicine - Division of Hematology and Oncology


I’m a motivated and energetic young scientist who received his Ph.D in Microbiology and Molecular Genetics from Michigan State University in 2010 (advisor: Andrea Amalfitano). I'm focused on my main goal: to develop a competitive research program in an independent extramurally funded research laboratory to help with important public health problem. My short-term goals are to keep actively publishing research papers, try to obtain my own independent research funding (K22, upon completion current F32), become an active member in the professional societies: American Association of Immunologists (AAI) and American Gastroenterological Association (AGA). My specialty is evaluating and modifying innate and adaptive immune responses in animal models of infections diseases (MCMV, Listeria monocytogenes, Clostridium difficile) and chemically-induced colitis and identifying functions of specific populations of immune cells in mediating these immune responses (NK, CD8+ T, NKT cells, Ly6C-hi inflammatory monocytes, neutrophils).

Research Interests

I'm interested in understanding how the host immune system and the gut microbiota modulate intestinal inflammation and carcinogenesis using mouse models. Specifically, we have focused on understanding the mechanism by which certain members of the Nod-like receptor (NLR) family that are largely involved in the sensing of bacteria or tissue damage protect against the development of inflammation-induced colitis and colon tumorigenesis. We are also investigating how the gut microbiota regulates colon tumorigenesis using germfree and gnotobiotic mice as well as attempting to identify tumor-suppressive and tumor-promoting bacterial populations through bacterial sequencing and analysis of stool from wildtype and NLR-deficient mice during the development of chemically-induced inflammation and tumors.
