WebDec 1, 2024 · The evolutionary conservation of KNDy neurons and at least two of their neuropeptides (kisspeptin and NKB) are essential for normal GnRH secretion in humans [10, [52], [53], [54], [55]].KNDy and kisspeptin neurons interact with the GnRH in the hypothalamus region of the brain, as shown in Fig. 1.GnRH pulse generation as shown by multiple unit … WebNov 1, 2015 · KNDy neurons form an interconnected network through neurokinin B signaling ( 12, 16) that synchronizes bursts of electrical activity which correlates with LH secretion ( 17, 18 ). For that reason, these neurons have been postulated to be a key component of the GnRH pulse generator that governs pulsatile secretion of GnRH and LH.
