Allogeneic haemopoietic stem cell transplantation (HSCT) is increasingly used to
treat haematological malignant diseases via the graft-versus-leukaemia (GvL) or
graft-versus-tumour effects. Although improvements in infectious disease
prophylaxis, immunosuppressive treatments, supportive care, and molecular based
tissue typing have contributed to enhanced outcomes, acute graft-versus-host
disease and other transplant related complications still contribute to high
mortality and significantly limit the more widespread use of HSCT. Sphingosine
1-phosphate (S1P) is a zwitterionic lysophospholipid that has been implicated as
a crucial signaling regulator in many physiological and pathophysiological
processes including multiple cell types such as macrophages, dendritic cells, T
cells, T regulatory cells and endothelial cells. Recent data suggested important
roles for S1P signaling in engraftment, graft-versus-host disease (GvHD), GvL and
other processes that occur during and after HSCT. Based on such data,
pharmacological intervention via S1P modulation may have the potential to improve
patient outcome by regulating GvHD and enhancing engraftment while permitting
effective GvL.
