Endothelial TSP1 and anti-thrombotic protection in DVT

Official title: Regulatory Mechanisms of the Vessel Wall in Thrombosis

Funded at University of Wisconsin-Madison · NIH-11431068 · Data updated 2026-11-12

A research team at UW–Madison is studying how a protein on blood vessel linings, TSP1, helps prevent clots in veins and what happens when it’s missing.

Who could benefit from this research

Could help

Ideal candidates are patients with or at risk for deep vein thrombosis and who could benefit from new anti-clot strategies in the future.

Less likely to help

Patients not at risk for DVT or those whose condition is unrelated to endothelial TSP1 signaling may not benefit.

What this research studies

The project uses a mouse model of deep vein thrombosis to explore how endothelial cells control clotting, focusing on thrombospondin-1 (TSP1) and its effect on inflammation and oxygen-sensing pathways. Researchers will test whether blocking or boosting HIF1α signaling can reverse the worsened clotting seen when endothelial TSP1 is deleted, and they will study these mechanisms in human iPSC-derived endothelial cells. The study combines animal experiments with cellular models to map the signaling pathway that keeps veins from forming dangerous clots. If successful, this work could reveal new targets to reduce clots without increasing bleeding risk.

Why it matters

Potential benefit: Understanding endothelial TSP1’s protective role could lead to safer anticoagulant strategies that minimize bleeding.

How similar studies have gone: Previous approaches using endothelial signaling pathways have shown promise in reducing thrombosis without excessive bleeding, but this specific TSP1–HIF1α axis is novel.
