Research on activity of IL-2,IL-6,IL-10 experimental allergic encephalomyelitis in monkey / 中华神经科杂志

ABSTRACT

Objective To investigate the change of the concentration of IL-2?IL-6?IL-10 in peripheral blood and cerebral spinal fluid (CSF) in monkey's experimental allergic encephalomyelitis (EAE),as to explaining it's function in mechanism and prognosis of the disease. Methods First set up animal models of monkey's EAE. Then separate the animals by their onset symptoms according to the level and the different stages of disease. At the same time survey the blood and CSF concentrations of IL-2?IL-6?IL-10, finally process the findings statistically. Results IL-2 in the first or the third week in the acute stage of EAE (5.0?0.8 and 5.3?1.2,respectively) was obviously higher than that (0.7?0.3) before the onset,P=0.045,0.041 respectively,both IL-6 and IL-10 in recuperation or chronic stage were higher significantly than before the onset,P=0.004 3,0.006 5 respectively. The findings were significant statistically. Conclusion IL-2 up-regulates immunologically,which accelerates the disease. IL-6 and IL-10 down-regulate immunologically,which reduce the disease. The findings may play an important role in studying immunological mechanism of EAE or MS in the future.
