The drugs work by preventing an enzyme called tyrosine kinase from launching a signalingcascade that fuels tumor cell growth.
这些药物的作用机制是阻断酪氨酸激酶启动信号级联反应，后者可以促进肿瘤细胞生长。

In such cases the chain of steps is referred to as a "signalingcascade" and often results in a small stimulus eliciting a large response.
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。

CD200 and CD200R binding the system function which was triggered by intracellular signalingcascade, control and reduce the activation of monocyte-macrophage system.
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。
