摘要

本研究旨在探讨HIF-1α、VEGF、VEGFR-2、VCAM-1和IL-4在高原牦牛和平原黄牛脾脏中的分布和表达特征,并推测HIF-1α及其相关缺氧诱导因子在牦牛脾脏适应高原缺氧环境中可能发挥的调控作用。用H&E和PAS染色观察组织学特征。免疫组化染色和光密度分析研究了牦牛和牛脾脏中HIF-1α、VEGF、VEGFR-2、VCAM-1和IL-4的分布和表达差异。结果表明,牦牛脾小梁和脾结节的面积明显大于黄牛(PPP

Differential expression of HIF-1α and its hypoxia-related inducers in the spleens of plateau yaks and plain yellow cattle.

The present study aims to investigate the distribution and expression characteristics of HIF-1α, VEGF, VEGFR-2, VCAM-1, and IL-4 in the spleen of plateau yaks and plain yellow cattle and to speculate the possible regulatory role of HIF-1α and its related hypoxia-inducible factors in the adaptation of the yak spleen to the plateau hypoxic environment. Histological features were observed using H&E and PAS stains. Immunohistochemical staining and optical density analysis were applied to investigate the distribution and differences in the expression of HIF-1α, VEGF, VEGFR-2, VCAM-1, and IL-4 in the spleen of yaks and cattle. The results showed that the area of splenic trabeculae and splenic nodules was significantly larger in the yak than in yellow cattle (P<0.05). Glycogen was mainly distributed in splenic arterial endothelial cells, vascular smooth muscle cells, splenic blood sinusoidal endothelial cells, and fibroblasts, and the distribution was significantly higher in the spleen of yaks than in cattle (P<0.05). HIF-1α, VEGF, VEGFR-2, VCAM-1, and IL-4 were mainly expressed in lymphocytes, arterial endothelial cells, vascular smooth muscle cells, splenic blood sinusoidal endothelial cells, and fibroblast cytoplasm, with higher expression in yak spleen (P<0.05). In conclusion, combining the differences in spleen tissue structure, glycogen distribution, and expression distribution of several hypoxia-related factors between yaks and cattle, we suggest that HIF-1α, VEGF, VEGFR-2, VCAM-1, and IL-4 may be important factors in the adaptation of yak spleen to the plateau environment, which provides a theoretical basis for further exploring the adaptation mechanism of plateau hypoxia in yaks.

期刊介绍: HISTOLOGY AND HISTOPATHOLOGY is a peer-reviewed international journal, the purpose of which is to publish original and review articles in all fields of the microscopical morphology, cell biology and tissue engineering; high quality is the overall consideration. Its format is the standard international size of 21 x 27.7 cm. One volume is published every year (more than 1,300 pages, approximately 90 original works and 40 reviews). Each volume consists of 12 numbers published monthly online. The printed version of the journal includes 4 books every year; each of them compiles 3 numbers previously published online.
