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