    Detoxified Pneumolysin Derivative ΔA146Ply Inhibits Autophagy and Induces Apoptosis in Acute Myeloid Leukemia Cells by Activating mTOR Signaling

    Scientists showed that ΔA146Ply, a mutant of pneumolysin that lacked hemolytic activity, inhibited autophagy of triple-negative breast cancer cells by activating mannose receptor and toll-like receptor 4 and that tumor-bearing mice tolerated ΔA146Ply well.

    Improved Outcomes of Single-Unit Cord Blood Transplantation for Acute Myeloid Leukemia by Killer Immunoglobulin-Like Receptor 2DL1-Ligand Mismatch

    To investigate their role in AML, mismatch of KIR2DL1, KIR3DL1, and KIR3DL2-ligand were retrospectively assessed in patients undergoing cord blood transplantation with graft-versus-host disease prophylaxis comprising a calcineurin inhibitor plus methotrexate or mycophenolate mofetil.
