ASSESSMENT OF SYNDECAN-4 EXPRESSION IN THE HEARTS OF TRYPANOSOMA CRUZI-INFECTED MICE AND HUMAN SUBJECTS WITH CHRONIC CHAGAS DISEASE CARDIOMYOPATHY
Author

Abstract
Chronic Chagas cardiomyopathy (CCC) is characterized by the presence of a multifocal inflammatory
response and myocardial damage, leading to fibrosis, arrhythmias and ventricular dysfunction. The expression of
syndecan-4, a transmembrane proteoglycan, was previously found to be increased in the hearts of mice chronically
infected with Trypanosoma cruzi. The possible involvement of syndecan-4 in the disease pathogenesis, however,
remains unknown. Here we evaluated the pattern of expression of syndecan-4 in the heart tissue of T. cruzi infected
mice and subjects with Chagas cardiomyopathy, correlating with the degree of inflammation and fibrosis.
