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.
