How Somatostatin Receptor Subtypes Differently Suppress GHRH vs GHRP-Stimulated GH Release
Somatostatin receptor subtypes 2 and 5 differentially suppressed GHRH-stimulated versus GHRP-stimulated GH secretion in a clinical study, revealing pathway-specific somatostatin inhibition that explains GH pulse regulation.
Quick Facts
What This Study Found
SST2/SST5 receptor activation differentially suppressed GHRH-stimulated and GHRP-2-stimulated GH secretion patterns in healthy men, with different effects on GH mass, frequency, and regularity — revealing receptor-specific modulation of the two GH-releasing pathways.
