β cell expression of IL-1β during development of diabetes in Psammomys obesus. Double immunostaining for IL-1β in red (b, d, and f) and insulin in green (a, c, and e) in tissue sections of pancreata from a fasted Psammomys obesus on a low-energy diet (blood glucose 4 mM) (a and b), from an animal on a high-energy diet for 8 days without injection (blood glucose 13.6 mM) (c and d), and with injections of the glucopenic drug phlorizin (blood glucose 5.6 mM) (e and f). Magnification: ×250.
