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 human pituitary tissue, DSIP was colocalized in about 75% of CLIP-immunoreactive cells in the anterior pituitary and residual intermediate lobe cells.

    In plain wordsIn human pituitary tissue, the body's own DSIP was found in about 75% of cells that also held CLIP.

    Summary · context
    DSIP and CLIP [ACTH(18-39)] immunoreactive (IR) neurons and fibers were examined in the human hypophysis and pituitary stalk using immunmohistofluorescence and peroxidase-antiperoxidase methods.

    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 human pituitary tissue, a high density of DSIP-immunoreactive fibers was seen in the pituitary stalk.

    In plain wordsIn human pituitary tissue, many fibers that hold the body's own DSIP were seen in the pituitary stalk.
