Vascular biology: cellular and molecular profiling.

Area of Science:

• Cerebrovascular disease research
• Immunology
• Vascular biology

Background:

• Cerebrovascular atherosclerosis mechanisms are not fully understood, with remaining knowledge gaps.
• Peripheral blood cellular and molecular profiling offers new insights into ischemic stroke pathogenesis.

Purpose of the Study:

• To explore cellular and molecular profiling of peripheral blood for identifying stroke risk biomarkers.
• To investigate the role of specific T-cell subsets and endothelial cell microparticles in stroke recurrence and vascular risk.

Main Methods:

• Cellular profiling to analyze T-cell subsets (e.g., CD4(+)CD28(-)) and endothelial cell microparticles.
• Molecular profiling including gene expression (transcriptomics) and proteomic analyses.
• Analysis of peripheral blood and atherosclerotic plaques.

Main Results:

• Increased levels of proinflammatory T-cell subset (CD4(+)CD28(-)) are linked to stroke recurrence and mortality.
• Elevated levels of specific endothelial cell microparticle phenotypes suggest increased vascular risk in stroke patients.
• Potential for identifying gene and protein panels predictive of stroke risk.

Conclusions:

• Cellular and molecular profiling of peripheral blood holds promise for stroke risk prediction.
• These studies may lead to novel therapeutic targets for primary and secondary stroke prevention.
• Understanding these peripheral markers could elucidate pathogenic mechanisms of ischemic stroke.
