Serum Eosinophil Cationic Protein as a Biomarker of Asthma Severity and Disease Control: A GINA-Based Case–Control Study in Adults
Background: Eosinophil cationic protein (ECP) is a unique polypeptide containing 133 amino acids that possesses ribonuclease 3 activity. ECP is a critical marker in the pathophysiology of asthma and serves as a cytotoxic protein secreted by activated eosinophils; hence this biomarker also indicates eosinophilic airway...
