Our previous work showed that under the condition of restraint stress and the control of central nervous system, a suppressive protein ( neuroimmune protein, NIP) was generated in peripheral lymph tissue and released into the blood stream, which acts as an immune suppressor. 我们曾经报道,大鼠或小鼠在束缚应激后血中产生了一种能抑制免疫功能的应激免疫抑制蛋白,(又称Neu-roimmuneprotein,NIP,神经免疫蛋白)。
