Figure 1
Schematic illustration of the interactions of leptin with the hypothalamic–pituitary–gonadal axis. Leptin stimulates POMC/CART
and Glut neurons and inhibits AgRP/NPY and GABA neurons to modulate reproduction centrally. At the ovaries, leptin can have
different effects depending on the metabolic status. AgRP, agouti-related peptide; CART, cocaine and amphetamine-regulated
transcript; FSH, follicle-stimulating hormone; GABA, gamma-aminobutyric acid; Glut, glutamate; GnRH, gonadotropin-releasing
hormone; LH, luteinizing hormone; NKB, neurokinin B; NPY, neuropeptide Y; PMV, ventral premammillary nucleus; POMC, proopiomelanocortin.
