Bacteroides acidifaciens derived pentadecanoic acid alleviates MAFLD by sensitizing senescent macrophages to ferroptosis via JNK-JUN-NCOA4 pathway

This study demonstrates that pentadecanoic acid, a metabolite derived from *Bacteroides acidifaciens*, alleviates MAFLD by sensitizing senescent macrophages to ferroptosis through the activation of the JNK-JUN-NCOA4 signaling pathway, thereby promoting their clearance and reducing hepatic steatosis.
