Cytokines are a group of proteins secreted by cells of the immune system that act as chemical messengers. Cytokines released from one cell affect the actions of other cells by binding to receptors on their surface. Through this process, cytokines help regulate the immune response. They act through receptors, and are especially important in the immune system; cytokines modulate the balance between humoral and cell-based immune responses, and they regulate the maturation, growth, and responsiveness of particular cell populations.
