Clinical Scorecard: A Closer Look at Vascular Cell States in Marfan Syndrome

At a Glance

Key Highlights

• Identification of 16 distinct vascular cell groups, including seven smooth muscle cell subtypes.
• Increased abundance of disease-enriched smooth muscle populations marked by LRP1 and PRSS2.
• Evidence of endothelial-to-mesenchymal transition in Marfan-associated endothelial cells.
• Integration of proteomic and transcriptomic data revealed additional Marfan-associated cell states.
• Need for functional studies on newly defined smooth muscle populations.

Guideline-Based Recommendations

Diagnosis

• Utilize single-cell proteomics to identify vascular cell states in Marfan syndrome.

Management

• Monitor changes in smooth muscle cell phenotypes and endothelial cell transitions.

Monitoring & Follow-up

• Assess the presence of Marfan-associated markers in vascular tissues.

Risks

• Increased risk of aortic aneurysm due to altered vascular cell states.

Patient & Prescribing Data

Patients diagnosed with Marfan syndrome, particularly those with aortic involvement.

Understanding of vascular cell states may inform targeted therapies for aneurysm prevention.

Clinical Best Practices

• Incorporate proteomic analysis in research to better understand Marfan syndrome pathology.
• Consider the heterogeneity of smooth muscle cell populations in clinical assessments.
