Zymosan A is widely used in biomedical research as a potent immune stimulant. It is commonly employed to study inflammatory responses and immune system activation, particularly in macrophages and other immune cells. Researchers utilize it to model and investigate conditions like sepsis, arthritis, and other inflammatory diseases. Additionally, Zymosan A is used to explore the mechanisms of phagocytosis and the role of pattern recognition receptors, such as Toll-like receptors, in immune signaling pathways. Its ability to activate the complement system also makes it valuable in studying innate immunity.
