Cellular signaling is a complex communication system essential for coordinating cellular activities and responses to environmental stimuli. It involves signaling molecules, receptors, and pathways that transmit and amplify signals to elicit specific cellular outcomes.

Cellular Signaling

Cellular signaling

A communication system is a framework that enables the transfer of information between entities through a set of processes and protocols, ensuring the message is transmitted accurately and efficiently. It encompasses various components such as transmitters, receivers, channels, and noise, and is fundamental to both human and machine interactions across diverse mediums.

cellular activities

Environmental stimuli refer to any external factors or changes in an organism's surroundings that elicit a response. These stimuli can include physical, chemical, biological, and social elements, influencing behavior, physiology, and development.

Signaling molecules are crucial biochemical entities that facilitate communication between cells, orchestrating complex biological processes and responses. They include a wide variety of molecules such as hormones, neurotransmitters, and cytokines, each playing specific roles in maintaining homeostasis and responding to external stimuli.

signaling molecules

Receptors are specialized protein molecules located on the surface of cells or within cells that bind to specific ligands, triggering a biological response. They play a crucial role in cellular communication, influencing numerous physiological processes and are essential targets in drug development.
