This interaction is highly specific, akin to a key fitting into a lock, where the structure of the signaling molecule determines which cells can receive the message. Autocrine signaling: A cell targets itself, often involved in processes like cell growth and proliferation.

Neurotransmitters: Chemicals like dopamine and serotonin that transmit signals across a synapse from one neuron to another. For example, beta-blockers interfere with adrenaline receptors to lower blood pressure and heart rate, while certain cancer therapies target growth factor receptors to halt the proliferation of malignant cells.
Signaling in Health and Disease When signaling pathways operate correctly, they maintain homeostasis, ensuring the body remains in a stable state. At its core, a signaling molecule is a specific substance that cells use to communicate, acting as a chemical messenger to coordinate complex biological processes.
