Semaglutide shifts human macrophages away from M1 phenotype via cAMP

The wire

1. 01Semaglutide at 100 nM cut CD80/CD86, TNF-alpha and IL-6 while raising CD206, CD163 and IL-10 in LPS/IFN-gamma polarized macrophages from two monocytic cell lines.
2. 02The work offers a direct anti-inflammatory mechanism for a GLP-1 agonist beyond weight loss, tied to GLP-1R and cAMP signaling and markers of mitochondrial biogenesis.
3. 03Findings come from immortalized cell lines only, with no animal or human confirmation, and mitochondrial biogenesis was inferred from ratio markers rather than measured function.
