The eosinophil cationic protein (ECP) is an antibiotic and anthelmintic produced by the human body . It is selectively synthesized in eosinophil granulocytes . Along with EDN, it is one of the main components of the eosinophilic granules. Both proteins are ribonucleases of the RNase A superfamily . Similar RNAses are found in all vertebrates .
effect
ECP is secreted by the eosinophilic granulocytes into the surrounding tissue as part of inflammatory reactions and has a local cytotoxic effect on various bacteria and parasites , but also on the body's own cells, e.g. B. on the epithelium in the airways.
Medical importance
The eosinophils play an important role in the pathogenesis of bronchial asthma . There is a close correlation between the number of eosinophils and the ECP concentration. Since there is also a correlation between the ECP concentration in the blood and the extent of the severity of the asthma, this parameter can e.g. B. contribute to monitoring the progress of asthma therapy.
