Cardiac Fibroblast and Macrophage

Caption

Colorized photomicrograph showing a macrophage (orange cell with large red nucleus in center of image) interacting with a fibroblast (blue cell with green nucleus at bottom right) in a mouse heart. Johns Hopkins Medicine researchers have shown that a protein, interleukin 17-A, can prevent critical monocyte cells from differentiating into lymphocytes that protect cardiac muscle from inflammation and in turn, lessen the threat of heart failure.
