Overview
Explanation
The correct answer is A. 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 but do not cause pain, produce antibodies, or directly kill microorganisms.
