New roles of plasminogen and the tiny particles it carries in blood

Novel functions of plasminogen and its diverse cargo in blood

NIH-funded research Vanderbilt University Medical Center · NIH-11324009

This work looks at how plasminogen, a common blood protein, carries small RNAs and lipids and how those cargoes influence immune cells and conditions like high cholesterol.

What this research studies

You might be asked to give a blood sample so researchers can isolate plasminogen and the tiny RNA- and lipid-bearing particles it carries. In the lab they will use methods like mass spectrometry and RNA sequencing to identify the proteins and small RNAs bound to plasminogen and compare profiles in people with high cholesterol. They will also expose immune cells to plasminogen in controlled experiments to see how gene activity and inflammatory signals change. Together these steps aim to map how plasminogen moves molecular signals between blood cells and whether that affects immune and metabolic health.

Who could benefit from this research

Good fit: Ideal participants would be adults willing to give blood samples, especially people with high cholesterol or related metabolic conditions.

Not a fit: People seeking an immediate treatment or those with health issues unrelated to blood, cholesterol, or immune signaling are unlikely to get direct benefit from participation.

Why it matters

Potential benefit: If successful, this could reveal new blood-based markers or targets that help manage inflammation and cholesterol-related disorders.

How similar studies have performed: Previous research has shown extracellular RNAs travel on lipoproteins and vesicles, but the idea that plasminogen itself carries functional small RNAs is a newer finding that is not yet clinically proven.
