AIMS/HYPOTHESIS: To study the effects of cereulide, a food toxin often found at low concentrations in take-away meals, on beta-cell survival and function.METHODS: Cell death was quantified by Hoechst/Propidium Iodide in mouse (MIN6) and rat (INS-1E) beta-cell lines, whole mouse islets and control cell lines (HepG2 and COS-1). Beta-cell function was studied by glucose-stimulated insulin secretion (GSIS). Mechanisms of toxicity were evaluated in MIN6 cells by mRNA profiling, electron microscopy and mitochondrial function tests.RESULTS: 24 h exposure to 5 ng/ml cereulide rendered almost all MI
