Abstract

The role of Zn2+ ions in proper storage of insulin in β-cell granules is well-established so when insulin is secreted from β-cells stimulated by an increase in plasma glucose, free Zn2+ ions are also released. This local increase in Zn2+ can be detected in the pancreas of rodents in real time by the use of a zinc-responsive MR contrast agent. This method offers the opportunity to monitor β-cell function longitudinally in live rodents. The methods used in our lab are fully described in this short report and some MR images of a rat pancreas showing clearly enhanced hot spots in the tail are presented.
