Joseph Reynolds graduated from the University of Louisville School of Medicine in 2007 with a Ph.D. in Microbiology and Immunology.  Working in the laboratory of Dr. Jill Suttles, he studied the effect of fatty acid-binding proteins (FABPs) in the regulation of inflammation and disease.  Their findings demonstrated that deletion of certain FABPs in macrophages and dendritic cells reduced inflammatory potential and protected against the development of autoimmune inflammation.

In 2008 Joseph joined the laboratory of Dr. Chen Dong in the Department of Immunology at the University of Texas MD Anderson Cancer Center to study the regulation and function of interleukin-17 (IL-17) and related IL-17 family cytokines.  Their primary discoveries were that IL-17 production by T lymphocytes could be regulated by innate signaling pathways, namely Toll-like receptors (TLR).  Moreover, direct TLR signaling in T lymphocytes positively regulated the development of IL-17-dependent inflammation.  Another project dealt with examining the function of an additional IL-17 family cytokine, IL-17C.  Their laboratory found that IL-17C signaling was important for IL-17 production from T cells.  Furthermore, they demonstrated that IL-17C was important for intestinal epithelial cell function and that IL-17C is protective against the development of acute colitis.  

In July 2013 Joseph joined the Department of Microbiology and Immunology in the Chicago Medical School at the Rosalind Franklin University of Medicine and Science as an Assistant Professor.

Research Interests

The overall goal of the laboratory is to further our understanding of mechanisms governing inflammatory responses and mucosal immunity.  Our research is currently focused on the role of the IL-17 family of cytokines in the promotion of inflammation and disease.  Research projects ongoing in the lab include:

The regulation of IL-17 production by T lymphocytes.  Our previous work has shown that both CD4+ T helper 17 (Th17) and gamma/delta T cells can respond to exogenous and endogenous TLR signals by producing IL-17.  The characterization of such innate-like pathways involved in the regulation of adaptive immune responses will further our understanding of the development and progression of inflammatory disease.  Moreover, we are interested in identifying how host-derived “danger” signals, such as endogenous TLR ligands, directly modulate T lymphocyte function in a disease setting.

IL-17C signaling in intestinal epithelial cells.  We are currently studying the roles of IL-17C in regulating colon epithelial cell function.  This project is based off of our previous finding that IL-17C is protective against the development of chemically-induced colitis.  Our studies now are focused on investigating the mechanisms responsible for these observations.

Additional IL-17 cytokines.  The IL-17 family consists of a group of 6 cytokines with varying degrees of homology (IL-17A-F).  Our laboratory is interested in examining the regulation and function of the more poorly described members of this cytokine family.
