IL-1 is primarily involved in the regulation of immune and inflammatory responses. It acts as a mediator in the acute phase of inflammation, affecting the function and behavior of various cells such as macrophages, neutrophils, and lymphocytes. IL-1 enhances the expression of adhesion molecules on endothelial cells, facilitating the migration of immune cells to sites of infection or injury. Additionally, IL-1 stimulates the production of other cytokines and chemokines, amplifying the inflammatory response.
