TLR4-defective mice display smaller infarct size at day 7 of reperfusion.

<p>Myocardial infarct size as a percentage of LV free wall was assessed by HE staining. Representative images show that infarct size is smaller in TLR4-defective mice than in TLR4-competent mice. Data are expressed as mean ± SE. n = 7 in each group; *<i>P</i><0.05 vs. TLR4-competent.
