[Research Progress on the Roles of Rapamycin for the Prophylaxis and Treatment of Graft-Versus-Host Disease --Review].

ABSTRACT

Graft-versus-host disease (GVHD) reduces the clinical effect and life quality of patients after allogeneic hematopoietic stem cell transplantation (HSCT). Especially for steroid-resistant GVHD, it becomes essential to explore new prevention and treatment strategies. Rapamycin has shown certain clinical advantages in the prevention and treatment of acute and chronic GVHD by inhibiting the mTOR signal pathway. Furthermore, rapamycin exhibits the ability to regulate cell subsets, including T cells, B cell, dendritic cells and myeloidderived suppressor cells, which elucidates the mechanism on effective preventing and treating GVHD. This article reviewed the roles of mTOR inhibitor-rapamycin on GVHD, and discussed how to optimize the usage of rapamycin.
