Figure 2From: Enhanced monocyte chemoattractant protein-1 production in aging mice exaggerates cardiac depression during endotoxemiaOld mice have higher levels of chemokines in the myocardium and plasma. Adult and old mice were treated with lipopolysaccharide (LPS, 0.5 mg/kg, iv) or normal saline. Levels of MCP-1 and KC were analyzed by ELISA 6 h after treatment. Old mice had higher levels of MCP-1 and KC in myocardial tissue (A) and plasma (B). Data are expressed as mean ± standard error. *P <0.05 versus corresponding control (Ctrl); #P <0.05 versus adult mice treated with LPS.Back to article page
