  1. 01LabIn vitro (cells)Activity measurement

    In dispersed fetal rat cerebral cortical and diencephalic cells, VIP caused a dose-dependent release of somatostatin.

    In plain wordsIn rat brain cells in culture, VIP made the cells release more somatostatin as the dose went up.

    Summary
    VIP elicited a dose-dependent release of somatostatin from both cortical and diencephalic cells, the lowest effective concentration being 6 X 10(-9) M.

    Summary · context
    dispersed fetal cerebral cortical and diencephalic cells grown in culture were exposed on day 10 or 11 of culture to various concentrations of VIP
  2. 02LabIn vitro (cells)Activity measurement

    In cultured fetal rat brain cells, VIP was more potent than PHI for somatostatin release; PHI was 0.06 to 0.1 times as potent as VIP.

    In plain wordsIn rat brain cells in culture, VIP caused somatostatin release at lower doses than PHI did.

    Summary
    PHI also brought about release of somatostatin, but was between 0.06 and 0.1 times as potent as VIP.

Studies that did not test the peptide alone1

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. 03LabNot a test of Vasoactive intestinal peptide (VIP, aviptadil) aloneIn vitro (cells)Activity measurement

    In cultured fetal rat brain cells, VIP and PHI together at 10(-7) M did not release more somatostatin than expected from an additive effect.

    In plain wordsIn rat brain cells in culture, VIP and PHI together did not add up to a larger somatostatin release.

    Outcome
    No significant changeSomatostatin release with VIP plus PHI together

    Summary
    Placed together in a concentration of 10(-7) M, the two peptides did not have an additive effect.
