OSI‐027 modulates acute graft‐versus‐host disease after liver transplantation in a rat model
Xiao Zhi, Fei Xue, Wei Chen, Chao Liang, Hao Liu, Tao Ma, Xuefeng Xia, Liqiang Hu, Xueli Bai, Tingbo Liang – 7 June 2017 – Despite its rarity (1%‐2%), acute graft‐versus‐host disease after liver transplantation (LT‐aGVHD) has a high mortality rate (85%). A gradual decrease in regulatory T cells (Tregs) correlates with disease progression in a rat LT‐GVHD model, and treatments which increase Tregs exert therapeutic effects on LT‐aGVHD. In this study, LT‐aGVHD model rats were treated with rapamycin (RAPA), OSI‐027, or an equal quantity of vehicle.
