Abstract

Mucosal immunology focuses on the complex interactions that occur at mucosal surfaces, which serve as the body’s primary defense against external pathogens. This article explores the synergy between innate and adaptive immunity in safeguarding mucosal barriers. The innate immune system provides immediate, non-specific protection through physical barriers and cellular components such as epithelial cells, neutrophils, and macrophages. In contrast, adaptive immunity offers specific, long-lasting protection mediated by T and B lymphocytes. Specialized immune structures known as mucosal-associated lymphoid tissue (MALT) orchestrate adaptive immune responses at mucosal sites. The communication and crosstalk between innate and adaptive immunity are facilitated by mechanisms such as antigen presentation and cytokine signaling. Understanding this dynamic interplay is crucial for developing effective mucosal vaccines and therapies. This comprehensive overview underscores the importance of coordinated immune responses in maintaining mucosal health and combating infections.
