Abstract

Mucosal surfaces represent the frontlines of the immune system, acting as the primary defense against various pathogens and environmental challenges. Understanding the complex mechanisms underlying mucosal immunology is crucial for developing effective strategies to combat infections and maintain overall health. This comprehensive review explores the latest advancements in the field of mucosal immunology, shedding light on the unique characteristics and functions of mucosal tissues, such as the respiratory, gastrointestinal, and genitourinary tracts. It delves into the diverse array of immune cells and molecular components that collaborate to establish and sustain mucosal immune responses, including the role of specialized secretory immunoglobulins, mucins, and antimicrobial peptides. Furthermore, the review examines the impact of environmental factors, microbiota, and vaccination on mucosal immunity. By unraveling the secrets of mucosal immunology, this work aims to emphasize the critical importance of preserving and fortifying our first line of defense for promoting global health and disease prevention.
