Core Tip
Core tip: Interference of immunosuppressive medication with liver regeneration is a highly relevant issue for transplantation of small-for-size liver grafts. Inhibition of mammalian target of rapamycin (mTOR) represents an important immunosuppressive strategy after transplantation, yet as mTOR regulates cell proliferation and autophagy, concerns remain regarding a negative impact on regeneration. The exact role of mTOR signaling after living-donor liver transplantation is largely unknown. Here we report that mTOR inhibition by rapamycin severely impairs liver regeneration and increases autophagy after liver resection in mice. The most novel finding of this study is that this impaired regeneration can be partly reversed by treatment with exogenous growth factors.
