The focus and long-term research goals of the Sonnenberg Laboratory are to interrogate the mechanisms by which the mammalian immune system controls tissue homeostasis, immunity, inflammation and cancer at mucosal barrier surfaces of the body. This is a considerable challenge given the enormous surface area of these sites, such as the gastrointestinal tract, which is home to an estimated 10 trillion microbes (termed the microbiota) and a majority of our body’s total immune system. While interactions between mammalian hosts and microbiota are normally beneficial, these interactions must be tightly regulated to prevent chronic inflammation. Studies in patient populations indicate that abnormal host immune responses to microbiota are causally-linked to the pathogenesis and progression of numerous chronic disorders, including inflammatory bowel disease (IBD), HIV/AIDS, viral hepatitis, cardiovascular disease, multiple sclerosis, Alzheimer’s diseases, autism, obesity, diabetes and cancer. Further, these interactions can influence the success or failure of multiple clinical therapies. Ongoing research in the Sonnenberg Laboratory aims to (1) interrogate the pathways that regulate normally beneficial host interactions with microbiota; (2) determine how these pathways become disrupted in multiple chronic human diseases; and (3) identify novel preventative, therapeutic or curative approaches to target the immune system and/or microbiota to benefit human health.

To better understand host-commensal bacteria interactions we have been studying the recently identified populations of intestinal-resident innate lymphoid cells (ILCs).  ILCs are an emerging family of immune cells that differentiate, independent of somatic recombination, from IL-7Rα+ Id2-dependent lymphoid progenitors. ILCs share striking similarities to heterogeneous populations of effector T cells.  As such, ILCs can currently be broadly classified into 3 groups based on their developmental requirements for specific transcription factors, common activating receptors and expression of effector cytokines.  Group 1 ILCs are T-bet+, activated by IL-18 and IL-12, and express IFNγ.  Group 2 ILCs are GATA-3-hi, activated by IL-25, IL-33 and TSLP, and express IL-4, IL-5, IL-9, IL-13 and amphiregulin.  Group 3 ILCs are RORγt-dependent, activated by IL-1β and IL-23, and express IL-22 and IL-17.  Importantly, group 3 ILCs have been found to be critical regulators of cytokine-mediated intestinal epithelial cell responses that promote immunity to extracellular bacteria, inflammation and tissue repair in the intestine.

We have also recently launched a pioneering translational research effort involving clinical collaborators at Weill Cornell Medicine and other research institutions to examine primary human samples from both healthy individuals and defined patient populations.  Our ongoing research will further interrogate mucosal immune responses and interactions with microbiota in healthy and diseased primary human tissue samples. We anticipate that these studies will allow us to directly translate our findings in mouse models to clinically relevant information.  

Talented graduate students and postdoctoral researchers are encouraged to directly contact Dr. Sonnenberg to discuss potential rotation projects and open positions in the laboratory.
