GH feedback occurs through modulation of hypothalamic somatostatin under cholinergic control: studies with pyridostigmine and GHRH
This randomized controlled trial examined the role of cholinergic modulation in growth hormone (GH) secretion, specifically investigating how pyridostigmine, a cholinesterase inhibitor, influences GH release through suppression of hypothalamic somatostatin. Pyridostigmine significantly increased GH secretion by enhancing cholinergic activity, which reduced somatostatin’s inhibitory effects, thereby promoting GH release. Though specific
