Mouse study maps kisspeptin control of GnRH neuron firing across hormone states
Photostimulated AVPV kisspeptin neurons raised GnRH neuron firing in a frequency-dependent way, but responses were blunted one week after ovariectomy.

The wire
- 01In acute mouse brain slices, photostimulation of AVPV kisspeptin neurons produced sustained, frequency-dependent increases in GnRH neuron firing; responses were similar in diestrus and proestrus but blunted one week post-ovariectomy.
- 02Kisspeptin is tracked on the sexual-health peptide beat, and the work details how ovarian steroids maintain the kisspeptin-GnRH circuit that drives the preovulatory surge.
- 03Monosynaptic connectivity was infrequent and consistently GABAergic; this is a slice electrophysiology study in mice and does not speak directly to kisspeptin dosing in humans.
