2. Figure 1
The absence of recipient perforin contributes to donor lymphoid cell engraftment. On day 0, C57BL/6 (WT) or C57BL/6.Pfn−/− (KO) mice were lethally irradiated (12 gray) and injected i.v. with 5e6 TCD-BM cells from BALB/c donors. On day 2, recipient mice were injected i.v. with 1e6 splenic BALB/c T cells. (A) On days 5 and 7, mice were killed and the spleen weight measured as a percentage of total body weight. (B) On day 7 after BMT, the splenocytes and BM cells of WT or KO mice were stained for H2Kd (donor cells), by flow cytometry, and engraftment determined as a percentage of donor lymphocytes. (C and D) On days 5 to 9 after BMT, serum was collected from WT or KO mice and measured for IFN-γ (C) or IL-6 (D) release, by Luminex assay. These data summarize 5 independent experiments using 5 mice per group. P < .05 (*), P < .01 (**), P < .001 (***), P < (****).

3. Figure 2
Differentiation of effector donor T cells occurs more rapidly in the absence of recipient perforin. On day 0, C57BL/6 (WT) or C57BL/6.Pfn−/− (KO) mice were lethally irradiated (12 gray) and injected i.v. with 5e6 TCD-BM cells from BALB/c donors. On day 2, these mice were injected i.v. with 1e6 splenic BALB/c T cells. On day 7, mice were killed and splenocytes stained with CD3, CD4, CD8, CD62L, and CD44 mAbs and fixable Live/Dead. Viable donor CD3+ T cells were analyzed by flow cytometry. (A) A representative FACS analysis contour plot indicating central memory (CM; CD62L+CD44+), and effector memory (EM; CD62L−CD44+) T cells. (B and C) The percentage of central memory and effector memory CD4+ (B) and CD8+ (C) T cells were compared between WT and KO BMT recipients 7 days post-BMT. These data summarize 3 independent experiments using 5 mice per group. P < .05 (*), P < .01 (**), P < .001 (***), P < (****).

Recipient NK cells mediate donor lymphoid cell rejection in a perforin-dependent manner. On days −1 and 0, C57BL/6 (WT) or C57BL/6.Pfn−/− (KO) mice were injected i.p. with 100 μL anti-Asialo GM1 (GM1) or PBS. On day 0, WT and KO mice were lethally irradiated (12 gray) and injected i.v. with 5e6 TCD-BM cells from BALB/c donors. On day 2, these mice were injected i.v. with 1e6 splenic BALB/c T cells. On day 7 after BMT, the splenocytes (A) and BM cells (B) of WT or KO mice were stained for H2Kd (donor cells), by flow cytometry, and engraftment determined as a percentage of donor lymphocytes. (C and D) On day 7 after BMT, serum was collected from WT or KO mice and measured for IFN-γ (C) or IL-6 (D) release, by Luminex assay. These data summarize 2 independent experiments using 5 mice per group. P < .05 (*), P < .01 (**), P < .001 (***), P < (****).

5. Figure 4
Anti-Asialo GM1 treatment depletes NK1.1+tetramer− cells in the BM but not the NK1.1+tetramer+ cells. On days −1 and 0, C57BL/6 (WT) mice were injected i.p. with anti-Asialo GM1 (GM1) or PBS. On day 0, WT mice were lethally irradiated (12 gray). On day 2 the BM cells were stained with CD3 and NK1.1 mAbs, CD1d-αGalCer tetramer, and fixable Live/Dead and analyzed by flow cytometry. The percentage of CD3+ T cells (A), NK1.1+CD3- NK cells (B), and NK1.1+CD3+ NKT cells (C) in viable BM cells were compared between untreated, irradiated, and irradiated + anti-Asialo GM1 treated mice. The percentage of NK1.1+tetramer− (D) and NK1.1+tetramer+ (E) cells in viable BM cells were compared between the same cohorts. These data summarize 2 independent experiments using 5 mice per group. P < .05 (*), P < .01 (**), P < .001 (***), P < (****).

6. Figure 5
Reduced TBI in perforin-deficient mice permits rapid donor lymphoid cell engraftment. On day 0, C57BL/6 (WT) or C57BL/6.Pfn−/− (KO) mice were irradiated with variable doses (12-6 gray) and injected i.v. with 5e6 TCD-BM cells from BALB/c donors. On day 2, recipient mice were injected i.v. with 1e6 splenic BALB/c T cells. On day 7 after BMT, the splenocytes (A) and BM cells (B) of WT or KO mice were stained for H2Kd (donor cells), by flow cytometry, and engraftment determined as a percentage of donor lymphocytes. On day 20 after BMT, the splenocytes (C) and BM cells (D) of WT or KO mice were stained for H2Kd (donor cells), by flow cytometry, and engraftment determined as a percentage of donor lymphocytes. (E) Survival of WT mice administered 12 gray (open circles), and KO mice administered 9 gray (closed circles), 7.5 gray (triangles), and 6 gray (squares) after BMT described above. (F) The percentage body weight of WT mice (12 gray [gray lines]), compared with KO mice (9 gray [black lines]) after BMT. These data summarize 2 independent experiments using 6 mice per group. P < .05 (*), P < .01 (**), P < .001 (***), P < (****).

7. Supplementary Figure 1
Spleen size after syngeneic BMT is similar in WT and KO recipient mice. On day 0, C57BL/6 and BALB/c (WT) or C57BL/6.Pfn−/− and BALB/c.Pfn−/− (KO) mice were lethally irradiated and injected i.v. with 5e6 TCD-BM cells from syngeneic donors. On day 2, recipient mice were injected i.v. with syngeneic splenic cells (1e6 BALB/c T cells or 2e5 C57BL/6 T cells). On day 7 mice were killed and the spleen weight measured as a percentage of total body weight. These data summarize 2 independent experiments using 4 mice per group.

9. Supplementary Figure 3
Perforin-deficient mice developed GVHD within 7 days post-BMT. On day 0, C57BL/6 (WT) or C57BL/6.Pfn−/− (KO) mice were lethally irradiated (12 gray) and injected i.v. with 5e6 TCD-BM cells from BALB/c donors. On day 2, recipient mice were injected i.v. with 1e6 splenic BALB/c T cells. On day 7 WT mice were killed and gut tissue fixed in 10% NBF. On day 9, pfn−/− mice scoring positive for GVHD were killed and gut tissue fixed in 10% NBF. Sections were stained using H&E and imaged on an Olympus BX-51 microscope, under ×20 magnification. Representative sections of gut tissue from WT mice (A) and KO mice (B) are shown. These data are representative of 5 independent experiments using 5 mice per group.
