Results from this study3

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

Natural levels measured3

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.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Other

    In the rabbit brain, the distributions of LHRH and DSIP immunoreactivity overlapped markedly through basal forebrain and hypothalamic regions.

    In plain wordsIn rabbits, the body's own DSIP and LHRH were found in largely the same brain regions.

    Summary
    The comparison of adjacent serial sections, one being immunolabeled with an antiserum to luteinizing hormone-releasing hormone, the other with an antiserum to delta sleep-inducing peptide, showed that the respective distribution patterns of immunoreactivity exhibited a remarkable overlap through the…

    Summary · context
    The anatomical distributions of luteinizing hormone-releasing hormone and delta sleep-inducing peptide immunoreactivity in the rabbit brain were studied by indirect immunofluorescence technique.

    This result measures the body's own Delta sleep-inducing peptide (DSIP). Nobody was given the peptide. It is not evidence about taking it.

    In the rabbit brain, all LHRH-immunoreactive cell bodies also showed DSIP immunoreactivity.

    In plain wordsIn rabbits, every brain cell body that contained LHRH also contained the body's own DSIP-like material.

    Summary
    A sequential double-immunolabelling (elution-restaining method) clearly indicated that all the luteinizing hormone-releasing hormone-immunoreactive cell bodies displayed delta sleep-inducing peptide immunoreactivity.

    In the rabbit brain, LHRH and DSIP immunoreactivity also colocalized in many fibres supplying these regions and terminal areas.

    In plain wordsIn rabbits, nerve fibres in several brain areas contained both LHRH and the body's own DSIP-like material.

    Summary
    The colocalization of luteinizing hormone-releasing hormone and delta sleep-inducing peptide immunoreactivity was also observed in many fibres supplying all these brain regions and terminal areas such as the organum vasculosum of the lamina terminalis, the subfornical organ, the median eminence and the pituitary stalk.
