How activated protein C helps protect blood vessel cells from damage

Official title: Endothelial Cytoprotective Signaling by Activated Protein C/Protease-activated Receptor-1

Funded at University of California, San Diego · NIH-10988298 · Data updated 2026-11-12

This study is looking at how a special protein called activated protein C can help protect the cells that line your blood vessels from damage, especially during serious conditions like sepsis, with the hope of finding new treatments for people with vascular diseases.

Who could benefit from this research

Could help

Ideal candidates for this research are patients with endothelial dysfunction related to vascular diseases, such as those experiencing sepsis.

Less likely to help

Patients with stable vascular conditions that do not involve endothelial dysfunction may not benefit from this research.

What this research studies

This research investigates how activated protein C (APC) can protect endothelial cells, which line blood vessels, from damage and dysfunction, particularly in conditions like sepsis. The study focuses on understanding the signaling pathways involved, specifically how APC interacts with a receptor called protease-activated receptor-1 (PAR1) to enhance cell survival and maintain the integrity of blood vessel barriers. By exploring these mechanisms, the research aims to identify new therapeutic targets that could improve treatment options for patients suffering from vascular diseases. Patients may benefit from potential new therapies that arise from this understanding.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that improve endothelial function and reduce complications in patients with vascular diseases.

How similar studies have gone: Previous research has shown promising results in using activated protein C for endothelial protection, indicating that this approach has potential for success.
