Cytokines are signaling molecules in the immune system that stimulate the production of white blood cells and help modulate the immune response. They are vital for coordinating responses to pathogens, enhancing inflammation, and regulating the immune system. Their primary function is to facilitate communication between cells in the immune response. ;
