Investigating the Role of A2A Receptor in Patients with High Cholesterol

Characterization of Adenosine A2A Receptor Expression and Fubnction in Hypercholesterolemic Patients

Not applicable Interventional Assistance Publique Hopitaux De Marseille · NCT05017649

This study is testing how high cholesterol affects certain receptors in the blood cells of patients to see if it helps explain the link between cholesterol and heart disease.

What this trial studies

This study aims to explore how hypercholesterolemia affects the expression and function of A2A receptors in peripheral blood mononuclear cells (PBMCs). By analyzing a larger cohort of hypercholesterolemic patients, the researchers hope to uncover the mechanisms linking high cholesterol levels to increased cardiovascular disease risk. The study will involve collecting blood samples to assess the A2A receptor's role in the cardiovascular and immune systems of these patients. Understanding these interactions may lead to improved prevention and treatment strategies for cardiovascular conditions associated with high cholesterol.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-80 with LDL-cholesterol levels greater than 1.9 g/L, with or without treatment for hypercholesterolemia.

Not a fit: Patients who do not have hypercholesterolemia or are currently on cholesterol-modifying therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prevention and treatment strategies for cardiovascular diseases in patients with hypercholesterolemia.

How similar studies have performed: While the specific role of A2A receptors in hypercholesterolemic patients is less explored, similar studies investigating receptor functions in cardiovascular conditions have shown promising results.
