WebNov 1, 2009 · Oestrogen has been shown to rapidly modulate multiple processes in embryonic and adult GnRH neurons including intracellular calcium levels, electrical activity and specific second messenger pathways, as well as GnRH secretion itself. WebApr 1, 2024 · Gonadotropin-releasing hormone (GnRH) is a decapeptide released from hypothalami, playing a central role in hypothalamic-pituitary-gonadal (HPG) axis for regulating reproduction in vertebrates [1]. GnRH functions by binding to its specific membrane receptor (GnRHR), a member of the G protein-coupled receptor superfamily.

WebMay 14, 2024 · Second messengers are molecules that relay signals received at receptors on the cell surface — such as the arrival of protein hormones, growth factors, etc. — to target molecules in the cytosol and/or nucleus. But in addition to their job as relay molecules, second messengers serve to greatly amplify the strength of the signal.
