Interleukin-1 potentiates glucose stimulated insulin release in the isolated perfused pancreas
Summary, in English
The acute effects of recombinant human interleukin-1 beta (rIL-1) on basal and glucose-stimulated insulin release were investigated in the isolated perfused pancreas. At a concentration of 20 μg/l rIL-1 had no effect on basal insulin release, but increased the total amount of insulin released during first and second phase insulin release in response to 20 mmol/l D-glucose in the rat pancreas (P < 0.05). In addition, 26 μg/l of rIL-1 potentiated insulin release in response to square wave infusions of stimulatory concentrations of glucose (11 mmol/l) in the porcine pancreas. We hypothesize that IL-1 in the systemic circulation may affect B cell function in vivo.
