Intercellular communication is part of a complex system of communication that governs basic cellular activities and coordinates cell actions 30 . In biology, cell signaling (cell signalling in British English) or cell communication is the ability of a cell to receive, process, and transmit signals with its environment and with itself. Gap junctions are composed of hexameric connexin oligomers that allow trafficking of small molecules between adjacent cells. •Indirect intercellular communication In each case, a specific chemical messenger, the signal molecule, is synthesized by specialized controlling cells to serve a designated purpose. Recent studies have revealed a global distribution of some perfluorinated organic compounds, especially perfluorooctane sulfonic acid (PFOS) in the environment. From: Cell Structure and Function by Microspectrofluorometry, 1989 These communication methods involve a number of different processes that occur individually or simultaneously, which change depending on the physiological or pathological context. Through extracellular chemical messengers or signal molecules . Steroid hormones––small, complex molecules involved in intercellular communication—are highly lipid soluble and have a variety of actions in the body and brain. Intercellular communication often proceeds in a pulsatile, rhythmic manner. - Provision for selective recognition of the arriving signal --> Accomplished by formation of a Receptor/Signal complex. Gap junctional intercellular communication (GJIC) is the major pathway of intercellular signal transduction, and is thus important for normal cell growth and function. Cell communication (biology) There are three different types of basic cell communication and they are: surface membrane to surface membrane, exterior, which is between receptors on the cell, and direct communication, which means signals pass inside the cell itself. Upon reception of a triggering stimulus, the signal is trans-formed into a chemical messenger within the signaling cell.
