The role of cardiac mast cells (MCs) in the progression to heart failure has recently become increasingly evident. Cathepsin g is a neutrophil- and mast cell-derived protease, which can convert angiotensin I to angiotensin II and thereby activate the TGF-beta pathway, resulting in myocyte necrosis, hypertrophy, and increased fibrosis. This study focuses on mast cell-derived cathepsin g in the human heart during heart failure and following mechanical unloading by means of heart-assist devices (LVADs).
