Mucosal Immunology

Mucosal immunology is the study of how our immune system protects the mucous membranes, which line various body parts like the nose, mouth, and intestines. These membranes are the first line of defense against germs and other harmful substances. Unlike the systemic immune response that protects the whole body, mucosal immunity focuses on localized responses, detecting threats and promoting healing while maintaining tolerance to harmless substances, such as food and beneficial microbes. Understanding this specialized immune function is essential for developing vaccines and treatments for infections and allergies affecting these surfaces.
