摘要 目的探索IL-6在实验性自身免疫性脑脊髓炎（EAE）中的作用机制。方法将25只雌性Wistar大鼠随机分为EAE组（n=15）、对照组（n=10）。利用免疫组化染色技术观察IL-6、TNF-α、TGF—β的表达，进行相关性分析。结果IL-6灰度值与症状评分呈负相关（r=-0．953，P〈0．05）、与TNF-α呈正相关（r=0．967，P〈0．05），IL-6与TGF—β呈无相关（r=-0．492，P〉0．05）.TNF—α灰度值与症状评分呈负相关（r=-0．978，P〈0．05），TNF—α与TGF—β无相关（r=-0．502，P〉0．05）。TGF-β灰度值与症状评分无相关（r=0．470，P〉0．05）。结论IL-6参与EAE的过程，可能是一种致炎因子。 Objective To explore the mechanism of IL-6 in EAE. Methods 25 female Wistar rats were randomly divided into 2 groups, EAE group（ n = 15） and normal control group（ n = 10）. The expression of IL-6, TNF-αand TGF-β of the two groups rats were observed by immunohistochemistry staining, and then correlation analysis of the expression of IL-6, TNF-αandTGF-β was made. Results There was negative correlation between gray scale of IL-6 and symptom scores（ r = -0. 953, P 〈 0. 05）. IL-6 and TGF-β had no statistical- ly significant correlation （ r = -0. 492, P 〉 0. 05 ）. There was negative correlation between gray scale of TNF-α and symptom scores（ r = -0. 978, P 〈0. 05）, and both of the correlation between TNF-α and TGF-β3 （ r = -0. 502, P 〉0. 05） , TGF-β and scores（ r =0. 470, P 〉 0. 05 ） were not statistically significant. Conclusions IL-6 may participate in EAE as a inflammatory factor.
