TRAIL expression is up-regulated in atrophic fibers of human myositis muscle. Tissue sections (n=4 per disease group) from myositis and muscular dystrophy muscle were stained for the presence of TRAIL. Intense intracellular TRAIL staining was seen in the perifascicular region of the DM muscle, whereas the PM muscle showed sporadic staining in some small degenerating fibers as well as interstitial cells. Normal and DMD tissues had no TRAIL staining on fibers. A representative example of the DM, normal, PM, and DMD samples is shown.
