Chief, Division of Allergy and Immunology - Northwestern University Feinberg School of Medicine
Stephanie Eisenbarth is Chief of Allergy and Immunology, and Director of the new Center for Human Immunobiology at Northwestern University’s Feinberg School of Medicine. Her research focuses on defining the cellular and molecular mechanisms that regulate antibody responses. In the allergy field, her lab discovered a new T follicular helper cell that drives IgE responses to allergens. This has important implications for potentially altering and tracking the inappropriate immune response to food allergens.

At FASI Stephanie Eisenbarth’s lab is investigating the role of gut IgA in food allergy. To understand the role of gut IgA her lab is using both human samples and mouse models to determine whether food-specific gut IgA impacts IgE sensitization and/or anaphylactic reaction to food allergens, defining the sub-anatomic location and clonal relationship between IgA versus IgE B cells induced to food antigens, and identifying the dendritic cell requirements for food-specific IgA versus IgE production in the gut. The results of this research could inform new therapeutic and diagnostic strategies for food allergy.
