Fabio Re graduated from the University of Milan in 1989. In the lab of Dr. Alberto Mantovani at the Mario Negri Institute for Pharmacological Research he conducted studies on the role of the Interleukin-1 receptor type II that led to the concept of “decoy receptor”, a paradigm later found to apply to other cytokine systems.
In 1994 he moved to Columbia University, New York, in the lab of Dr. Jeremy Luban where he studied the effect of HIV infection on cell cycle progression.
In 1999 he joined the lab of Dr. Jack Strominger at the Dana-Farber Cancer Institute, Boston, where he studied several aspects of the biology of toll-like receptors (TLR), including the differential activation of dendritic cells by TLR agonists and the interaction of LPS with TLR4/MD-2. During this period he held an Instructor position in the Department of Pathology of the Harvard Medical School.
In 2004 he was appointed Assistant Professor in the Department of Molecular Sciences at the University of Tennessee Health Science Center in Memphis. His research efforts remained focused on innate immunity. He was tenured and promoted to Associate Professor in 2010.
In 2012 he joined the Department of Microbiology and Immunology of Chicago Medical School at Rosalind Franklin University of Medicine and Science as Associate Professor.
Fabio serves as grant reviewer for the National Institute of Health, the National Science Foundation, and the Welcome Trust. He is Associate Editor for The Journal of Immunology and reviewer for several immunological journals.
The long-term goal of our lab is to augment our understanding of the role of Toll-like receptors (TLR) and Nod-like receptors (NLR) during innate and adaptive immune responses.
TLR and NLR recognize microbial products and endogenous “danger signals” and activate signaling pathways that initiate the inflammatory response and regulate development of adaptive immunity. Some NLR molecules are part of a multiprotein complex called inflammasome that is responsible for the proteolytic processing and secretion of IL-1b and IL-18.
Our lab investigates the activation of TLR and NLR in distinct experimental settings:
Most vaccine adjuvants stimulate the immune system by activating various innate immune receptors. We have found that the vaccine adjuvant Alum activates the NLRP3-inflammasome and we are investigating other pathways that contribute to alum’s adjuvanticity. Understanding at the molecular level the mechanism of action of alum and other adjuvants is a prerequisite for improvement of their immunostimulatory spectrum.
We are interested in defining the role of TLR and NLR during infections with the NAID Select Agents Francisella tularensis and Burkholderia pseudomallei. We are also investigating how the interaction of the intestinal microbiota with the host innate immune system shapes the response to infections and the development of immunity.
Tumorigenesis triggers an inflammatory response and, conversely, inflammation promotes malignant transformation. We are investigating how cancer-related inflammation is initiated and sustained with particular attention to the role of the inflammasome in cancer.
