• PKA-phosphorylation of Hsp20 is elevated in human failing hearts.
• Increases in phosphorylated Hsp20 in vivo are associated with fibrotic remodeling and reduced left ventricular function.
• The phosphorylated Hsp20 in cardiomyocyte promotes upregulation of IL-6 and its subsequent paracrine actions on the cardiac fibroblast.
• Blockade of IL-6 effects ex vivo and in vivo reduces the pro-fibrotic effects of phosphorylated Hsp20.
• Targeting phosphorylated Hsp20 in the cardiomyocyte may represent a potential therapeutic strategy to mitigate fibrotic remodeling and preserve function in the failing heart.
