Figure.. A model for regulation of pathological cardiac remodeling by extracellular CyPA.
Pathological stress in the heart results in increased expression of CyPA and release of extracellular CyPA (eCyPA) from cells. Binding to eCyPA to the EMMPRIN/CD147 receptor on cardiomyocytes stimulates ERK and possibly other signaling cascades, resulting in hypertrophy and stiffening of the cells. It is unknown whether cardiomyocytes that are stimulated with eCyPA activate cardiac fibroblasts and inflammatory cells through paracrine mechanisms, or if eCyPA directly engages these other cell types. The constellation of cardiomyocyte hypertrophy/stiffening, inflammation and fibrosis caused by eCyPA results in cardiac dysfunction and contributes to heart failure pathogenesis. Parts of this figure were made using BioRender.
