Research/Clinical Interest
Intestinal Immune Regulation in Health and Disease
Crohn’s disease and ulcerative colitis - the two main types of inflammatory bowel disease (IBD) - are believed to be due in part to a failure of intestinal immune regulation, enabling aberrant pro-inflammatory responses to the intestinal microbiota to ensue. The establishment and maintenance of intestinal immune homeostasis requires the coordinated actions of multiple cellular mediators that mitigate unwanted responses to the vast community of beneficial microbes that inhabit our gastrointestinal tract. Intestinal regulatory T cells (Treg cells) Treg cells are essential for promoting and maintaining this host-microbiota mutualism and hold tremendous potential for therapeutic intervention/manipulation in IBD. Thus, one area of our work aims to define the cellular and molecular pathways that enhance regulatory T cell function during chronic gut inflammation. In addition, antibody-secreting plasma cells in the gut and associated lymphoid tissues help to control the interactions of luminal microbial antigens with the immune system. Therefore, we are also interested in understanding the host and/or microbial pathways that enable antibody-mediated control of the commensal microbiota and how perturbation of these processes predisposes to acute intestinal inflammation. We utilize a diverse combination techniques – cellular and molecular immunology, microbiology – as well as mutant and gnotobiotic rodent models.
