Signaling Molecules

Signaling molecules are substances released by cells which propagate signals in a process called cell signaling. Signaling molecules can act like hormones, neurotransmitters, or cytokines and play a role in multiple functions of the body, such as development and regulation of behavior. Signaling molecules are essential in controlling communication between cells and guiding the activities of the entire organism. Thus, they are crucial for life as they are responsible for cell growth, differentiation, proliferation, and metabolism. The malfunction of signaling molecules can be associated with various diseases, such as diabetes and cancer. Therefore, understanding how signaling molecules work can help create novel treatments for these conditions.
