Kisspeptin Research

Kisspeptin is a naturally occurring neuropeptide encoded by the KISS1 gene. It is recognized as the central upstream regulator of the hypothalamic-pituitary-gonadal (HPG) axis, providing the primary signal for GnRH (gonadotropin-releasing hormone) release. Its discovery transformed understanding of reproductive hormone signaling.

Research Areas

GnRH Pulse Regulation

Research demonstrates that kisspeptin neurons in the arcuate nucleus (KNDy neurons) provide the primary upstream signal that drives GnRH pulsatility from the hypothalamus, making kisspeptin the 'master regulator' of the reproductive hormone axis.

LH & FSH Signaling

Clinical studies show that kisspeptin administration reliably stimulates LH (luteinizing hormone) and FSH (follicle-stimulating hormone) release in humans, with research exploring its role in both male and female hormonal signaling contexts.

Reproductive Hormone Research

Research explores kisspeptin's relevance to puberty onset signaling, fertility-related pathways, hypothalamic amenorrhea investigation, and its role in linking metabolic status to reproductive hormone signaling.

Mood & Social Signaling Research

Studies also investigate kisspeptin's potential interactions with mood pathways and sexual behavior neural circuits, with clinical research at Imperial College London examining psychosexual signaling effects.
