Laboratory of Mucosal Immunity, Immune Tolerance, and Host-Microbe Interactions
The Sonnenberg Laboratory investigates the complex cellular networks that preserve health in the gastrointestinal tract. By deciphering how the immune system balances tolerance to trillions of commensal microbes while defending against pathogens, we uncover foundational biology to fight chronic inflammatory diseases, autoimmune disorders, and cancer.
Research Directions
RORγt+ Antigen Presenting Cells
Characterizing the discovery and biology of distinct RORγt+ APC subsets in intestinal and lymphoid tissues, and uncovering their non-redundant roles in instructing immune tolerance.
Innate & Adaptive Lymphocyte Biology
Investigating the regulation of group 3 innate lymphoid cells (ILC3s) and regulatory T (Treg) cells along mucosal surfaces to maintain barrier integrity.
Host-microbe interactions in gut inflammation
Dissecting how commensal microbial consortia and dietary antigens communicate with the immune system to maintain metabolic homeostasis and modulate chronic inflammatory pathways.
Translational Human Mucosal Immunology
Translating preclinical discoveries to patient cohorts and biobanking to identify novel therapeutic targets for IBD, cancer, and systemic inflammation.
Areas of scientific investigation
Visualizing cellular architecture, microbial interfaces, and molecular pathways through advanced confocal, electron microscopy, and spatial segmentation.
