How Mounjaro Alters Craving Circuits in the Brain

A rare intracranial brain-recording study revealed that tirzepatide, a GLP-1 and GIP receptor agonist, temporarily silences craving-related neural activity in a key reward circuit of the brain. Using implanted electrodes in a patient with treatment-resistant obesity and loss of control eating, researchers observed that the drug initially shut down signaling in the nucleus accumbens.

How Zepbound Targets the Brain and Pancreas

A new imaging approach reveals how dual agonist drugs like tirzepatide act on the pancreas and brain to regulate blood sugar and appetite. Using fluorescent probes called daLUXendins, researchers visualized drug binding to insulin-producing beta cells and other pancreatic cell types, as well as brain regions tied to hunger regulation.
