Cellular Receptor Communication

Meaning

Cellular receptor communication describes the intricate process by which extracellular signaling molecules, such as hormones, neurotransmitters, and growth factors, bind to specific receptor proteins on or within a target cell to elicit a physiological response. This fundamental biological process is the core mechanism of intercellular communication, allowing the body’s systems to coordinate and respond dynamically to internal and external stimuli. Optimal cellular receptor communication is essential for maintaining homeostasis, facilitating tissue repair, and ensuring accurate hormonal signal transduction. Dysregulation in this pathway can lead to states of hormone resistance or exaggerated sensitivity.
