Role of rate of change of glucose concentration as a signal for insulin release
MD O'Connor, HD Landahl and GM Grodsky
In the isolated perfused pancreas, the amount of insulin secreted in
response to a glucose stimulus was evaluated as a function of the maximum
rate of change of the stimulus. Range of glucose concentration, total
amount of glucose, total duration of the changing stimulus, the average
concentration, and the average rate of change of concentration were the
same. Fast changes stimulated more insulin secretion than slow changes,
indicating that the rate-sensor property was inherent in the control of
insulin release.
