Macrophages play a key role in atherosclerosis through lipid uptake and inflammation. Here, the authors show that RNF128 promotes atherosclerosis by stabilizing scavenger receptor B1 (SRB1) via polyubiquitination, enhancing foam cell formation and inflammation, while its ablation reduces plaque formation in hyperlipidemic mice.
