Document Summary
General principles of cell signaling: signal transduction conversion of information of communication, signaling cell produces a signal molecule that is detected by a target cell, target cells have receptor proteins. Recognize and respond to the signal molecule. Regulating inflammation: autocrine signaling is a form of paracrine signaling, neuronal signaling delivered quickly and specifically to individual target cells, contact-dependent signaling allows adjacent cells to become specialized to form different cell types. Each cell responds to a limited set of signals, depending on its history and its current. State: whether a cell responds to a signal depends on, receptor protein, receptor membrane proteins proteins. Each receptor only activated by one type of signal. A cell"s response to a signal can be fast or slow. Some hormones cross the plasma membrane and bind to intracellular receptors: extracellular signal molecules two classes, molecules too large/hydrophilic to cross plasma membrane.
