What a great with Ivaylo Ivanov from Columbia University today at CeMM, hosted by our Scientific Director Maria Rescigno and PI Clarissa Campbell.
Ivanov’s lab studies how immune responses to commensal bacteria influence host physiology. In his talk, “Adaptive Immunity at the Host–Microbiota Interface,” he described their work on commensal-specific Th17 cells in regulating mucosal homeostasis and systemic metabolic disease. He highlighted the coordinated roles of intestinal epithelial cells, dendritic cells, and macrophages, revealing a division of labor between dendritic cells and macrophages in shaping commensal-specific immunity and protective mucosal T cell responses.
Ivaylo Ivanov is a Professor in the Department of Microbiology and Immunology at the Vagelos College of Physicians and Surgeons at Columbia University, where he heads the Laboratory for Mucosal Immunology. His research has been instrumental in defining how the microbiota interact with intestinal epithelial cells and regulate mucosal T cell differentiation and function. More recently, his group has also uncovered how interactions between diet, microbiota, and mucosal immunity can influence systemic diseases such as obesity.
Thank you, Ivaylo, for an insightful seminar on the complex dialogue between microbes and the immune system!
