Intricate Relationship Between Goblet Cells and the Gut Microbiome

In a new study, scientists from the University of California, San Diego have shed light on the crucial function goblet cells—specialized gut-lining cells—play in preserving a balanced and healthy immune environment in the gastrointestinal (GI) tract. Dr. Fernanda Raya Tonetti led the project, and Dr. Cristina Llorente made important contributions.
