title: TRAIL, caspases and maturation of normal and leukemic myeloid precursors.
abstract: Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/Apo2L) is a membrane-bound cytokine molecule that belongs to the family of tumor necrosis factor (TNF). Members of this family share diverse biological effects, including induction of apoptosis and/or promotion of cell survival. Identification of TRAIL has generated considerable enthusiasm for its ability to induce apoptotic cell death in a variety of tumor cells, by engaging the death receptors TRAIL-R1/DR4 and TRAIL-R2/DR5, while sparing most normal cells. Beside its anticancer activity, several studies have suggested a role for endogenously expressed TRAIL in hemopoiesis. In this review, we summarize the knowledge about the different lineage-specific roles of TRAIL and its receptors in hemopoiesis regulation. Moreover, the complex interplay among the signaling pathways triggered by TRAIL/TRAIL-receptors in myeloid cells is discussed in some detail.
