Boosting Apolipoprotein M Shows Promise in Slowing Age-Related Macular Degeneration

Researchers plan to translate improved retinal health seen in mice into potential AMD treatments through a WashU startup partnership.

Overview

  • Patients with AMD exhibit lower circulating ApoM levels than healthy individuals.
  • ApoM orchestrates beneficial cholesterol pathways and activates lysosomal acid lipase to clear excess lipids.
  • Elevating ApoM in mouse models reduced retinal lipid deposits and restored photoreceptor function.
  • Beneficial outcomes depend on ApoM’s binding to sphingosine-1-phosphate to trigger lipid catabolism.
  • Researchers have founded Mobius Scientific to advance ApoM-based treatments for AMD and possibly heart failure.
