Circulating endothelial cells: the role in aging and brain pathology

Area of Science:

• Vascular Biology
• Biomarkers
• Gerontology

Background:

• Circulating endothelial cells (CECs) are mature vascular cells normally found in low numbers in peripheral blood.
• Increased CEC levels are observed in various diseases, reflecting endothelial cell turnover or injury.
• CEC counts can fluctuate significantly in diseased individuals.

Purpose of the Study:

• To review the role of CECs as biomarkers in aging and brain disorders.
• To explore the relationship between CECs, pathological conditions, and disease prognosis.
• To provide insights into the potential for CECs in disease prevention and treatment.

Main Methods:

• Literature review focusing on CECs in pathological conditions.
• Analysis of studies investigating CECs in elderly patients and those with brain disorders.
• Examination of CECs as biomarkers in hematological diseases and cancers.

Main Results:

• CEC concentration is elevated and variable in diseased patients.
• Changes in CEC count correlate with disease progression, treatment response, and prognosis.
• CECs are implicated in endothelial damage and serve as biomarkers for tumor vascularity and therapy monitoring.

Conclusions:

• CECs are valuable indicators of endothelial cell changes and disease states.
• Studying CECs under pathological conditions is crucial for understanding their role in aging and brain disorders.
• CECs offer potential for improved disease monitoring, prognosis, and therapeutic strategies.
