Article Title: The designer cytokine IC7Fc attenuates atherosclerosis development by targeting hyperlipidemia in mice

doi: 10.1126/sciadv.adx3794

Figure Lengend Snippet: IC7Fc signaling lowers hepatic de novo lipogenesis and modulates bile acid metabolism, which increases plasma bile acid levels following reduced hepatic reuptake of bile acids. The inhibition of transcription factor HNF4α contributes to the reduced synthesis and secretion of APOB-containing VLDL particles. This leads to the attenuation of hyperlipidemia and atherosclerosis development. gp130, coreceptor glycoprotein 130; IL-6R, interleukin-6 receptor; LIFR, leukemia inhibitory factor receptor. Solid lines, up-regulated process; dashed lines, down-regulated process; green arrow, up-regulated; red arrow, down-regulated. Created in BioRender. In het Panhuis, W.
