FIG. 4.
σ1s is required for maximal myocardial tissue injury. The degree of injury in the myocardium, as measured by quantifying H&E-stained heart sections, was significantly reduced in σ1s− (C84-MA) virus-infected mice. Each bar represents the average score from 10 to 13 mice. Error bars indicate standard errors of the means. *, P < 0.05.
