Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In the dragonfly Aeschna cyanea, the brain, suboesophageal ganglion and corpora cardiaca were immunoreactive to VIP antiserum.

    In plain wordsIn dragonflies, nerve tissue reacted to an antibody against VIP, suggesting the body's own VIP-like peptide is present.

    Summary
    the brain, the suboesophageal ganglion and the corpora cardiaca of the dragonfly Aeschna cyanea have been shown to be immunoreactive to proctolin antiserum and to several mammalian peptide antisera including unsulfated cholecystokinin octapeptide (CCK-8 NS) (Andriès et al. 1989), vasoactive intestinal peptide (VIP)

    This result measures the body's own Vasoactive intestinal peptide (VIP, aviptadil). Nobody was given the peptide. It is not evidence about taking it.

    In the dragonfly brain and suboesophageal ganglion, cells reactive to both hGRF and VIP antisera also showed gastrin/CCK-like immunoreactivity, and some were detected by motilin antiserum.

    Summary
    Multiple peptide immunoreactivities appear expressed in the brain and the suboesophageal ganglion. Cells reactive to both hGRF and VIP antisera show also gastrin/CCK-like immunoreactivity and some of them are also detected by motilin antiserum.

    This result measures the body's own Vasoactive intestinal peptide (VIP, aviptadil). Nobody was given the peptide. It is not evidence about taking it.
