TWEAK/Fn14 axis in cardiovascular disease. Schematic representation of TWEAK roles in pathological cardiovascular remodeling diseases. TWEAK in cardiovascular diseases (CVDs) affect inflammatory cells, cardiomyocytes, fibroblasts, endothelial and smooth muscle cells (SMCs) in CVDs. TWEAK/Fn14 axis interaction promotes pathological tissue remodeling; atherosclerosis (inflammation, lipid accumulation and plaque progression, and instability), restenosis (SMCs proliferation, migration, and cyclins regulation), heart failure (cardiomyocytes dysfunction and fibrosis), abdominal aortic aneurysm (inflammation, matrix degradation, AAA progression, angiogenesis).
