Immunobiology
Mucosal immunity refers to the specialized immune responses that occur at mucosal surfaces, which include the gastrointestinal tract, respiratory tract, and urogenital tract. This form of immunity is crucial for protecting the body against pathogens that enter through these surfaces while maintaining tolerance to non-harmful antigens, such as food proteins and commensal bacteria. Mucosal immunity involves various immune cells and molecules, primarily located in mucosal-associated lymphoid tissue (MALT), ensuring effective responses to infections while preventing unnecessary inflammation.
