A Closer Look at Vascular Cell States in Marfan Syndrome
Single-cell proteomics identifies Marfan-enriched smooth muscle states and endothelial transition signatures
Clinical Scorecard: A Closer Look at Vascular Cell States in Marfan Syndrome
At a Glance
| Category | Detail |
|---|
| Condition | Marfan Syndrome |
| Key Mechanisms | Altered vascular cell states and smooth muscle phenotype changes associated with aneurysm development. |
| Target Population | Individuals with Marfan syndrome, particularly those at risk for aortic aneurysms. |
| Care Setting | Research laboratories and clinical settings focusing on vascular pathology. |
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.
