By engineering loss- (\n              <jats:italic>\n                Grem2\n                <jats:sup>\u2212\/\u2212<\/jats:sup>\n              <\/jats:italic>\n              ) and gain- (\n              <jats:italic>TG<\/jats:italic>\n              <jats:sup>Grem2<\/jats:sup>\n              ) of-Grem2-function mice, we discovered that Grem2 controls the magnitude of the inflammatory response and limits infiltration of inflammatory cells in peri-infarct ventricular tissue, improving cardiac function.

Furthermore, intraperitoneal administration of Grem2 protein in wild-type mice was sufficient to reduce inflammation after MI. Cellular analyses showed that BMP2 acts with TNF\u03b1 to induce expression of proinflammatory proteins in endothelial cells and promote adhesion of leukocytes, whereas Grem2 specifically inhibits the
