Results from this study1

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

Natural levels measured1

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)Mechanism

    In rats, intracerebroventricular AgRP did not significantly change Fos expression in oxytocin neurons of the paraventricular nucleus versus saline.

    In plain wordsIn rats, AgRP did not change activity markers in the body's own oxytocin neurons compared with saline.

    Summary
    In the paraventricular nucleus, there was no significant difference in Fos expression induced by AgRP vs. saline in oxytocin and CART neurons.
    1 context sentence
    Summary · context
    Thus we aimed to identify the neurochemical phenotype of some of these neurons in select hypothalamic areas, using double-label immunohistochemistry.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.
