The role of inflammatory macrophages in pathophysiology of experimental autoimmune myocarditis
Ontology highlight
ABSTRACT: Myocarditis is an inflammatory disease of the cardiac muscle characterized by an influx of inflammatory cells, predominantly of myeloid lineage. The progression of myocarditis to a dilated cardiomyopathy phenotype and heart failure is markedly influenced by TGF-β signalling. The aim of this study was to investigate the role of TGF-β signalling in inflammatory cardiac macrophages in the development of myocarditis and post-inflammatory fibrosis. Experimental autoimmune myocarditis (EAM) was induced in the LysM-Cre x R26-stop-EYFP x Tgfbr2-fl/fl transgenic mice showing impaired TGF-β signalling in the myeloid lineage and the LysM-Cre x R26-stop-EYFP control mice. Inflammatory macrophages were sorted from the inflamed hearts and analyzed for differential gene expression using whole genome transcriptomics.
