Mouse Brain Study Reveals Why Blockbuster Weight-Loss Drugs May Work Differently in Females and Males
Researchers at Icahn School of Medicine created the first sex‑specific atlas of GLP‑1 expression in the mouse brain using RNAscope, mapping the peptide across 25 nuclei. The atlas shows pronounced differences between females and males, especially in hindbrain nuclei of the solitary tract and in the olfactory bulb. These anatomical disparities may explain why GLP‑1‑based weight‑loss drugs such as semaglutide have variable efficacy between sexes. The work also highlights GLP‑1 presence in regions linked to reward and cognition, opening avenues for psychiatric and Alzheimer’s research.
