A research-context examination of semaglutide’s GLP-1 receptor-mediated modulation of arcuate nucleus POMC/AgRP neuronal circuits, intracellular PI3K/AKT/AMPK cascades, and the translational limitations observed between rodent and human hypothalamic preparations.

An examination of how retatrutide’s glucagon receptor component engages the hepatic cAMP-PKA-CREB signaling cascade and modulates gluconeogenic enzyme transcription in preclinical cell and animal models.

An examination of retatrutide’s GIPR-specific binding geometry, including cryo-EM structural data and mutagenesis findings from cell-based cAMP assays.
