Research Interests:

Dr. Shea-Donohue’s research is focused on immune-based alterations in gastrointestinal function.  A major goal of the work is to determine the contribution of non-immune cells to cytokine-induced alterations in gut function, particularly, the interaction between non-hematopoeitic cells and immune cells in mediating both transient and long term changes induced by upregulation of specific profiles of cytokines.  The balance of immune-derived cytokines in vivo is critical to the control of infectious diseases, but polarization of the cytokine balance towards the Th1 or Th2 can have consequences that are inappropriate to host defense against agents that have different requirements for elimination.  The mechanisms responsible for the Th1 and Th2-mediated immune response are of interest for several reasons.  First, intestinal parasites continue to be a major worldwide health issue; second, the low incidence of parasite infection in industrial nations is cited as a factor in the increased prevalence of proinflammatory-based pathologies such as inflammatory bowel disease (IBD); and third, there is a seemingly paradoxical protection against Th2-mediated allergic reactions, both in the lung and gut, afforded by enteric infection.

We are currently exploring the mechanisms that regulate Th2 cytokine and cytokine receptor expression and the genes activated downstream receptor linked STAT signaling pathways.   The focus is on genes that are mediate the immune-induced alterations in epithelial cell and smooth muscle function.   The goal is to better understand the fate of these pathways in diseases such as IBD which are characterized by an immune balance and are associated with diarrhea.  Although a current therapeutic target in IBD is reduction of Th1 cytokine activity, an alternate approach is to rectify the Th1/Th2 cytokine imbalance by increasing Th2 cytokines.  The recent clinical success of therapies directed at targeting Th 2 cytokines provides a more specific therapeutic approach to the treatment of IBD than that offered by the standard anti-inflammatory and anti-immune regimens.
