Definition
Cell communication, or cell signaling, refers to the complex processes by which cells send, receive, and respond to chemical signals, enabling them to coordinate their activities and maintain homeostasis. This communication can occur through direct contact, the release of signaling molecules, or the activation of specific receptors on target cells.
Summary
Cell communication, or cell signaling, is a fundamental process that allows cells to interact and coordinate their activities. It involves the transmission of signals through various molecules, including hormones and neurotransmitters, which bind to specific receptors on target cells. This interaction triggers a cascade of events within the cell, leading to a specific response, such as growth, division, or apoptosis. Understanding cell signaling is essential for many fields, including medicine and biology, as it plays a critical role in processes like immune responses and the development of diseases such as cancer. By studying how cells communicate, researchers can develop targeted therapies and better understand the underlying mechanisms of various health conditions.
