Beneficial effects of seaweed-derived active substances on immunoregulatory function

Abstract

Seaweed polysaccharides are among the most important marine plant resources currently being developed, and their immunomodulatory activity has received widespread attention. However, there is still a paucity of the latest summary of the in-depth immune mechanisms of these seaweed polysaccharides. Therefore, in this review, seaweed polysaccharides that have been proven to have immunomodulatory properties were reported.A detailed summary of the three main aspects of the immune mechanism is provided, namely, regulating the immune system to fight against pathogens, clearing tumor cells in the body, and inhibiting the damage of excessive inflammatory factors to the immune system. This comprehensive analysis provides a scientific framework for the development of seaweed 2 polysaccharides as immune modulators and their application in food and cosmetics.
