TWEAK induces chemokine protein expression and peritoneal inflammation in mice <i>in vivo</i>.

<p><b>A and B</b>) Increased MCP-1 (<b>A</b>) and CCL21 (<b>B</b>) protein expression in mesothelium from mice 24 h after TWEAK injection. <b>C</b>) F4/80 antigen immunohistochemistry. An increased number of submesothelial macrophages stained with F4/80 were noted 24 h after TWEAK injection (arrows). Controls for the technique are stained with nonspecific Ig. Images representative images of 5 animals per group.
