Effects of perforin- or FasL-deficient CD8+T cells on acute GVHD. Lethally irradiated bm1 mice received transplants as described in “Materials and methods” from wt B6 (wt), perforin-deficient B6 (pfp–/–), or Fas ligand–deficient B6 (gld) donors. Syngeneic B6 BM transplant recipients (syn) served as no-GVHD controls. At 30 days after BMT, liver and intestine (bottom column [•], small intestine; upper column, large intestine) were harvested and scored semiquantitatively (n = 4 mice/group). Data represent mean ± SD.
