摘要

研究了8周龄非肥胖型糖尿病(NOD)小鼠和低剂量链脲佐菌素(LDS)小鼠细胞间粘附分子-1 (ICAM-1)的表达。在NOD小鼠中,ICAM-1在胰岛周围(对应于胰岛周围静脉网络)、胰岛内以及胰腺外分泌部分间隔的分散元件上表达。图像分析显示,与NOD小鼠相比,lds治疗的动物胰岛内和周围的ICAM-1免疫反应性较低。在超微结构水平上,发现胰岛周围血管充满单核元素。内皮细胞有活化的迹象,单核细胞和多形核白细胞出现边缘。

Intercellular adhesion molecule-1 (ICAM-1) expression in the islets of the non-obese diabetic and low-dose streptozocin-treated mouse.

The expression of intercellular adhesion molecule-1 (ICAM-1) was studied in 8-week-old non-obese diabetic (NOD) mice and low-dose streptozocin-treated (LDS) mice. ICAM-1 expression in NOD mice was observed at the islet periphery, corresponding to the peri-islet venular network, within the islet and on scattered elements along septa of the exocrine portion of the pancreas. Image analysis demonstrated that LDS-treated animals had less ICAM-1 immunoreactivity within and around the islets compared to NOD mice. At the ultrastructural level the peri-islet vessels were found to be filled with mononuclear elements. Moreover, endothelial cells showed signs of activation, and margination of monocytes and polymorphonuclear leukocytes was observed.
