The anti-inflammatory pathways modulated by GLP-1 receptor activation (NF-kB suppression, macrophage polarization, Treg enhancement) are largely distinct from the pathways targeted by: Methotrexate: Folate metabolism disruption, different anti-inflammatory pathway TNF inhibitors (adalimumab, etanercept): Direct TNF blockade, whereas GLP-1 reduces TNF production upstream IL-6 inhibitors (tocilizumab): Receptor-level blockade, while GLP-1 reduces IL-6 production JAK inhibitors (tofacitinib, baricitinib): Different signaling pathway entirely Corticosteroids: Broad immunosuppression, while GLP-1 is immunomodulatory This pathway complementarity is why additive benefit is biologically plausible
These two powerhouse compounds are not just essential for maintaining youthful skin
Furthermore, systematic in vitro evaluation of MMF with co-medications may help elucidate the exact molecular mechanisms of DDIs, which may facilitate the development of mechanistic PK models to promote individualized MMF therapy
