Cell Signaling and Communication

Cell signaling is the ability of a cell to receive, process, and transmit signals with its environment and with itself.

Signals that originate from outside a cell can be physical agents like mechanical pressure, voltage, temperature, light, or chemical signals (e.g., small molecules, peptides, or gas).

Cell signaling can occur over short or long distances, and as a result can be classified as autocrine, juxtacrine, intracrine, paracrine, or endocrine.
