信号级联放大(signaling cascade) 从细胞表面受体接收外部信号到最后作出综合性应答是一个将信号逐步放大的过程，称为信号的级联放大反应。
这些信号级联放大系统中转导途径是否平衡决定了机体有无疾病。
The balance between these pathways determines the outcome as a diseased or non-diseased state.
在这种情况下，这一连串的步骤被称为信号级联放大，通常由一个微小的刺激所引发，由大量反应而告终。
In such cases the chain of steps is referred to as a "signaling cascade" and often results in a small stimulus eliciting a large response.
CD 200与CD 200r结合触发细胞内信号级联放大的系统功能，控制并下调单核巨噬细胞系统的活化。
CD200 and CD200R binding the system function which was triggered by intracellular signaling cascade, control and reduce the activation of monocyte-macrophage system.
