RESEARCH SUMMARY

It has become increasingly evident that interactions between the enteric nervous system (ENS) and the immune system play important roles to modulate inflammatory responses. Such interaction is particularly critical in the context of the intestinal microenvironment given the unique properties of this organ: intestinal tissue is continuously exposed to numerous microbial and food-derived antigens. In order to deal with these stimuli yet maintain normal physiology and function, intestinal responses are tightly regulated by actions of both the immune and nervous systems, which co-localize in the intestinal microenvironment with close proximity. Our lab mainly studies the role of intestinal neuroimmune interactions in health and disease. Understanding the cellular and molecular mechanisms of the dynamic interplay between the ENS and the immune system is critical for retrieving a comprehensive view of intestinal homeostasis and for discovering new therapeutics for intestinal inflammatory diseases, such as inflammatory bowel diseases (IBD).

Mucus sialylation determines intestinal host-commensal homeostasis

Published Date

Sialylation is critical for intestinal mucus formation. Yao et al. (1172–1188) show that a local sialyltransferase in the gut, ST6GALNAC1 (ST6), determines mucin protein sialylation, protecting mucus barrier integrity from bacterial degradation. ST6-mediated mucus homeostasis in turn controls commensalism to establish intestinal host-microbial symbiosis. ST6 deficiency disrupts this mutualism, enhancing susceptibility to intestinal inflammation. The cover image illustrates that sialylated mucin proteins (saguaros with thorns) harbor symbiotic commensal bacteria (gilded flickers), protecting the intestinal tissue from pathogens (snakes and hawks). Loss of sialylation (saguaros without thorns) results in pathogenic bacteria invasion (snakes). Illustration concept by Chuan Wu and artwork by Alan Hoofring.

Galectin-9-CD44 interaction enhances stability and function of adaptive regulatory T cells

Published Date

Galectin-9 can dampen autoimmune responses, and this process is associated with an increase in the frequency of inducible regulatory T (iTreg) cells. We show that galectin-9 potentiates the signal transduction of transforming growth factor βR (TGF-βR), a critical receptor for iTreg cell differentiation. Potentiation results in increased activation of Smad3 with subsequent enhanced transcription of the iTreg cell differentiation factor, FoxP3. The cover image illustrates T lymphocytes emerging from a microenvironment (represented by a fabricator) influenced by the presence of TGF-β. With assistance from galectin-9 and its receptor CD44, the differentiation process to iTreg cells is enhanced. Image by Chuan Wu.
