RT Journal Article T1 Vitamin D: Effect on Haematopoiesis and Immune System and Clinical Applications. A1 Medrano, Mayte A1 Carrillo-Cruz, Estrella A1 Montero, Isabel A1 Perez-Simon, Jose A K1 allogeneic stem cell transplantation K1 haematopoiesis K1 leukaemia K1 myelodysplastic syndrome K1 vitamin D AB Vitamin D is a steroid-like hormone which acts by binding to vitamin D receptor (VDR). It plays a main role in the calcium homeostasis and metabolism. In addition, vitamin D display other important effects called "non-classical actions." Among them, vitamin D regulates immune cells function and hematopoietic cells differentiation and proliferation. Based on these effects, it is currently being evaluated for the treatment of hematologic malignancies. In addition, vitamin D levels have been correlated with patients' outcome after allogeneic stem cell transplantation, where it might regulate immune response and, accordingly, might influence the risk of graft-versus-host disease. Here, we present recent advances regarding its clinical applications both in the treatment of hematologic malignancies and in the transplant setting.
