The messages carried by ATP are received on the surface of cells by specific receptors, which I termed purinoceptors, because ATP belongs to a group of chemicals known as purines.
由ATP携带的信息接收细胞表面的特定受体，我把它称为嘌呤受体，因为ATP属于嘌呤的一种。

There is substantial molecular, cellular and system-level evidence that extracellular ATP, via activation of purinoceptors, plays important roles during physiological and pathological processes.
