Figure 5. TRAIL-treatment improved survival of CASP.

Figure 5

This effect was abrogated by depleting neutrophils. A: Survival of CASP is depicted as Kaplan Meier curves. Mice were treated with anti-Ly6G 24 hrs before CASP induction (anti-Ly6G) to deplete neutrophils. Controls received appropriate isotype controls (isotype). Neutrophil-depleted (anti-Ly6G, TRAIL) and untreated mice (TRAIL) received TRAIL (1 µg/g (wt/wt)) 1 h, 24 h and 48 h after CASP intravenously. TRAIL treatment significantly improved survival of sepsis in previously untreated mice (p<0.001). However, TRAIL-treatment was ineffective in Ly6G-depleted mice. B: Depletion of neutrophils was confirmed via FACS analyses. Representative data 48 hrs after neutrophil depletion are shown. The oval indicates neutrophils detected via CD11b+Ly6Cmed expression.
