摘要: 本试验旨在比较研究不同牛肝组织中IL-17和HSP90的分布及表达差异。分别选取5例健康成年牦牛、犏牛及黄牛,取肝组织,采用HE染色、免疫组织化学染色及实时荧光定量研究肝组织学结构特点、蛋白阳性定位及基因定量表达。HE染色结果显示,肝细胞呈索状排列,肝索之间的肝血窦中有少量的淋巴细胞和枯否细胞;免疫组织化学染色结果显示,IL-17和HSP90在牦牛、犏牛及黄牛肝细胞的细胞质中表达;免疫组化半定量和实时荧光定量的结果一致,在犏牛肝表达量最高,牦牛次之,黄牛最低(P <0.01)。IL-17和HSP90基因在牦牛、犏牛和黄牛肝中表达的差异说明具有种属特异性;IL-17和HSP90蛋白半定量阳性结果说明相对于黄牛肝,犏牛和牦牛肝对温差变化等刺激具有更好的适应性。

Abstract: The aim of this study was to study the distribution and quantification of IL-17 and HSP90 in liver tissues of different cattle, and to compare the positive reaction and differential expression of IL-17 and HSP90 in the liver tissues of Yak, Cattle-yak and Yellow cattle. Liver samples of healthy adult Yak, Cattle-yak and Yellow cattle (n=5) were selected, respectively. HE, immunohistochemical, and Quantitative Real-time PCR methods were used to observe the histological features, protein positive localization, and gene quantification of liver, respectively. Results showed that:hepatic cells were arranged in a cord-like manner, and a small number of Lymphocytes and Kupffer's cells were found in the blood sinuses between the hepatic cords (HE staining). Both IL-17 and HSP90 were expressed in the cytoplasm of liver cells of Yak, Cattle-yak and Yellow cattle (Immunohistochemical results). The results of Immunohistochemistry Semi-quantitative, and Quantitative Real-time PCR were consistent. The highest expression was found in the liver of Cattle-yak, followed by Yak, and the lowest in Yellow cattle (P < 0.01). Differential expression of IL-17 and HSP90 genes in liver of Yak, Cattle-yak and Yellow cattle shows species specificity. Semi-quantitative positive results of IL-17 and HSP90 protein showed that the liver of Yak and Cattle-yak had better adaptability to temperature differences than the liver of Yellow cattle.
