PS1145 treatment of alloreactive T-cells significantly reduces their capacity for GVHD lethality in primary host-type recipients. (A) 105 vehicle-cultured cells or PS1145 cultured (10 µM) cells recovered from B6 anti-bm12 day 7 from MLR cultures established with whole CD4+ T-cells or CD4+CD25− T-cells and injected into sublethally irradiated bm12 recipients (n=5 to 10/group). (B) 105 vehicle-cultured cells or PS1145-cultured (10 µM) cells recovered on Balb/c anti-B6 day 5 from MLR cultures established with whole CD25− T-cells and injected into sublethally irradiated CB6F1 SCID recipients (vehicle n=8, PS1145-treated n=16, p=9.24×10−7).
