Results from this study5

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

Natural levels measured5

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 mice, three populations of kisspeptin neurons were identified in the AVPV/PeN, dorsomedial hypothalamus and arcuate nucleus.

    Summary
    Three populations of kisspeptin neurons located in the 1) anteroventral periventricular nucleus (AVPV) and the preoptic periventricular nucleus (PeN), 2) dorsomedial hypothalamus, and 3) arcuate nucleus were identified using an antisera raised against mouse kisspeptin-10.

    Summary · context
    We examined here the postnatal development of kisspeptin neuronal populations and their projections to GnRH neurons in the mouse.

    This result measures the body's own Kisspeptin-10. Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    In mice, the AVPV/PeN had about 10-fold more kisspeptin neurons in females than in males (P<0.01), with no sex difference elsewhere.

    In plain wordsIn mice, females had about ten times more of the body's own kisspeptin-making brain cells than males in one region.

  3. 03AnimalEndogenous levelAnimal study (in vivo)Other

    In mice of both sexes, AVPV/PeN kisspeptin neurons were absent at postnatal day 10 and increased from day 25 to adult levels by puberty onset (P<0.01).

    In plain wordsIn mice, the body's own kisspeptin-making brain cells appeared after day 10 and reached adult numbers by puberty.

    Summary
    Kisspeptin neurons in the AVPV/PeN of both sexes displayed a similar pattern of postnatal development with no cells detected at postnatal day (P) 10, followed by increases from P25 to reach adult levels by puberty onset (P<0.01; P31 females and P45 males).
