How fibrinogen becomes fibrin and why that matters for blood clots

Coagulations 'Drake Passage': The Bumpy Transition Between Fibrinogen and Fibrin

NIH-funded research East Carolina University · NIH-11122886

We are finding molecular differences between fibrinogen and fibrin to help people with clot-related problems like heart disease, stroke, and Alzheimer’s-related vascular damage.

What this research studies

Researchers at East Carolina University will study the two closely related blood proteins, fibrinogen and fibrin, using lab techniques from biochemistry and biophysics to map how their shapes and binding sites differ. They will look for molecular signatures that mark fibrin versus fibrinogen and test how those differences relate to pathological deposits linked to disease. The project also trains students in these lab methods so future teams can translate the findings toward diagnostics or therapies. Most work happens in the lab on protein samples and molecular assays rather than as a clinical treatment trial.

Who could benefit from this research

Good fit: People with conditions tied to abnormal fibrin deposits—such as certain cardiovascular diseases, stroke survivors, or those with Alzheimer’s-related vascular changes—would be the most relevant candidates for future related trials or sample donation.

Not a fit: People whose health problems are unrelated to blood-clotting or fibrin biology are unlikely to see direct benefit from this research.

Why it matters

Potential benefit: If successful, this work could lead to tests or treatments that specifically detect or target harmful fibrin deposits, improving diagnosis and care for clot-related conditions.

How similar studies have performed: Previous research has linked fibrin to disease and shown it can be harmful in some contexts, but fibrin-specific diagnostics and therapies remain largely novel and unproven.
