Abstract: The body defense mechanism has evolved to protect animals from invading pathogenic microorganisms and cancer. It is able to generate a diverse variety of cells and molecules capable of specifically recognizing and eliminating a limitless variety of foreign invaders. These cells and molecules act together in a dynamic network and are known as the immune system. Innate mucosal immunity consists of various recognition receptor molecules, including toll-like receptors, NOD-like receptors, and RIG-I-like receptors. These recognition receptor molecules recognize various invading pathogens effectively, and generate an immune response to stop their entry and neutralize their adverse consequences, such as tissue damage. Furthermore, they regulate the adaptive response in cases of severe infection and also help generate a memory response. Most infections occur through the mucosa. It is important to understand the initial host defense response or innate immunity at the mucosal surface to control these infections and protect the system. The aim of this review is to discuss the effects and functions of various innate mucosal agents and their importance in understanding the physiological immune response, as well as their roles in developing new interventions.
