Research at Mass General
Research in my lab is focused on three areas:
In each of these projects, we use a combination of in vitro and in vivo experiments to clarify the mechanisms that contribute to alterations in immune function.
The overall goal of these studies is to understand basic principles in immunoregulation in the gut and to use this information to shed light on diseases in which intestinal immunity is disturbed.

The inverse correlation between exposure to helminthes (parasitic worms) and the incidence of certain immune-mediated diseases, including inflammatory bowel diseases (IBD), has been evidenced from epidemiological studies.
The distribution of several pathogenic helminth infections coincides geographically with many devastating microbial diseases, such as HIV, malaria, and tuberculosis.
Infections with intestinal helminths and enteric bacterial pathogens, such as enteropathogenic Escherichia coli (EPEC), continue to be a major global health threat, especially for children.
However, the nature of the interaction and the exact mechanism by which helminth modulates the host’s response to concurrent pathogens are still unclear.
Our laboratory investigates the role of helminth parasites in evoking a T helper cell intestinal response and its effect on bacterial invasion.
We are particularly interested in exploring the mechanisms by which the helminth parasite modulates intestinal mucosal response to enteric bacteria and bacteria-associated intestinal inflammation using a co-infection model system.
This system involves two murine enteric infectious agents that induce distinct Th responses: (i) the helminth Heligmosomoides polygyrus (Th2) and (ii) the Gram-negative bacterium Citrobacter rodentium (Th1).
Research in the Shi lab has shown that helminth co-infection results in an impaired host protection and the development of more severe C. rodentium-mediated intestinal inflammation by a STAT 6 (Th2) dependent mechanism. Dr. Shi has also shown that the helminth modulates host response via the effect of dendritic cells.
In collaboration with Dr. Allan Walker, Dr. Shi also examines the impact of intestinal colonization of bacteria (probiotics) during early life on the development and regulation of mucosal T cell responses (Th1, Th2 and T regs) and explores the mechanisms by which probiotics modulate host protection against enteric pathogens.
Using both in vivo and in vitro approaches, Dr. Shi examines and defines the conditions under which dysregulation of intestinal mucosal response to luminal antigens triggers the development of intestinal inflammatory responses that ultimately result in chronic inflammatory disease.
His research will provide greater insight about how intestinal microorganisms may alter the regulatory mechanisms of mucosal immunity, which may be instrumental in the establishment of effective preventive and therapeutic approaches for the treatment of Th1- and Th2-mediated diseases and for the design of effective intestinal vaccines.
