Our previous work demonstrated that under the conditions of restraint stress and under the control of central nervous system (CNS), an immune suppressive protein of stress (ISPS) was generated in peripheral lymph tissue and released into the blood stream, which acts as an immune suppressor.In the present work the cellular source of ISPS was studied.Firstly,the extracts from various cell types were prepared and the identification was performed by bioassay of lymphocyte proliferation.The results showed that the extract of mononuclear
