消息传递英语:Signal transduction;也译作信号转导消息传导等)是指细胞外的消息经过一系列的生化反应之后,活化了细胞内部的消息,进而使细胞产生一些反应。这些消息可能是光线、抗原、细胞表面的糖蛋白、发育消息、生长因子、激素(赫尔蒙)、神经传导物质或营养物质等。

负责细胞外消息传递到细胞内部的传导物则主要可分6种,包括离子信道闸门(gate ion channel)、受体酵素(receptor enzyme)、弯曲形受体(serpentine receptor)、类固醇受体(steroid receptor)、粘着受体(adhesion receptor)以及本身不含酵素的受体。

消息传递概观。

Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, eventually eliciting a response. Depending on the cell, the response may alter the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can generate a response involving hundreds to millions of molecules.
