The kisspeptin system of the human hypothalamus: sexual dimorphism and relationship with gonadotropin-releasing hormone and neurokinin B neurons.
Erik Hrabovszky,Philippe Ciofi,Barbara Vida,Miklós Horváth,Eva Keller,Alain Caraty,S.R. Bloom,M. A. Ghatei,Waljit S. Dhillo,Zsolt Liposits,Zsolt Liposits,Imre Kalló,Imre Kalló +12 more
TL;DR: The distribution and robust sexual dimorphism of kisspeptin‐immunoreactive elements in human hypothalami is described, neuronal contacts between kisspeptins and neurokinin B fibers and GnRH cells are revealed, and co‐synthesis of Kisspeptin and neuroKinin B in the infundibular nucleus is demonstrated.

Evidence for suprachiasmatic vasopressin neurones innervating kisspeptin neurones in the rostral periventricular area of the mouse brain: regulation by oestrogen.
Barbara Vida,Levente Deli,Erik Hrabovszky,Theodosis Kalamatianos,Alain Caraty,Clive W. Coen,Zsolt Liposits,Zsolt Liposits,Imre Kalló,Imre Kalló +9 more
TL;DR: The results are consistent with the hypothesis that KP neurones located in the mouse AVPV/PeN receive circadian information from the SCN via a vasopressinergic monosynaptic pathway, which is enhanced by oestrogen.

Oestrogen Receptor α and β Immunoreactive Cells in the Suprachiasmatic Nucleus of Mice: Distribution, Sex Differences and Regulation by Gonadal Hormones
TL;DR: The sexually differentiated expression and distribution of ERα and ERβ in various cell populations of the SCN suggest multiple modes of oestrogen signalling within this nucleus, which may modulate circadian functions.

Sexual dimorphism of kisspeptin and neurokinin B immunoreactive neurons in the infundibular nucleus of aged men and women
Erik Hrabovszky,Csilla S. Molnár,Máté T. Sipos,Barbara Vida,Philippe Ciofi,Beáta Á. Borsay,Laszlo Sarkadi,László Herczeg,Stephen R. Bloom,Mohammad A. Ghatei,Waljit S. Dhillo,Imre Kalló,Imre Kalló,Zsolt Liposits,Zsolt Liposits +14 more
TL;DR: Overall, sex differences in reproductive physiology of aged humans were reflected in the dramatic sexual dimorphism of the KP system, with significantly higher incidences of KP-IR neurons, fibers and inputs to GnRH neurons in aged females vs. males.

Morphological evidence for enhanced kisspeptin and neurokinin B signaling in the infundibular nucleus of the aging man.
Csilla S. Molnár,Barbara Vida,Máté T. Sipos,Philippe Ciofi,Beáta Á. Borsay,Kálmán Rácz,László Herczeg,Stephen R. Bloom,Mohammad A. Ghatei,Waljit S. Dhillo,Zsolt Liposits,Erik Hrabovszky +11 more
TL;DR: Robust aging-dependent enhancements were identified in the regional densities of KP-IR perikarya and fibers and the incidence of afferent contacts they established onto GnRH neurons, and these changes are compatible with a reduced testosterone negative feedback to KP and NKB neurons.
