  1. 01LabEx vivo tissueEfficacy outcome

    In the isolated perfused rat pancreas, 750 pM porcine VIP markedly enhanced insulin release in response to 5.5 or 16.7 mM glucose, and 250 pM was still effective.

    In plain wordsIn lab tests on perfused rat pancreas, porcine VIP clearly increased glucose-induced insulin release, even at a lower concentration.

Studies that did not test the peptide alone2

In this study, Vasoactive intestinal peptide (VIP, aviptadil) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Vasoactive intestinal peptide (VIP, aviptadil).

  1. 04LabNot a test of Vasoactive intestinal peptide (VIP, aviptadil) aloneEx vivo tissueMechanism

    In the isolated perfused rat pancreas, somatostatin at 10 ng/ml blocked the stimulatory effect of both VIP molecules on glucose-induced insulin secretion.

    In plain wordsIn lab tests on perfused rat pancreas, somatostatin blocked the insulin-raising effect that VIP had on its own.

    Summary
    After suppression of VIP and somatostatin from the perfusion medium, insulin release increased to levels higher than those with glucose alone in the case of the avian peptide, but not in that porcine VIP.
