  13. Slide 13: Summary

    Summary • Preclinical data show that in DIO mice, Inhbe GalNAc-siRNAs: - Lower Inhbe mRNA and induce weight loss mainly through reduction of fat mass - Reduce pro-inflammatory macrophage recruitment in adipose tissue - Double weight loss, when added on to semaglutide - Curtail weight regain upon ces
