Filter by:Bone marrow consists of a complex hematopoietic cellular component.When the blood progenitor cells differentiate to mature cells, they will exit unassisted to peripheral blood. On the other hand, the immature cells trapped by marrow-blood barrier. However, malignant transformation of the hematopoietic progenitor cells in AML and CML results in a blockade of their ability to terminally differentiate, causing a rapid accumulation of immature cells.Chemokines have been shown to direct the movement of cells between intravascular and extravascular compartments.The CXC chemokine CXCL12, the ligand of CXCR4, activates distinct signaling pathways that may mediate cell migration.In the preliminary research, we analyze the CXCR4 expression and the chemotactic response of CXCL12 and peripheral plasma in six leukemia cell lines (HL-60, HL-CZ, K562, U937, Raji and Jurkat) and found that three categories among them could be suggested: one is CXCR4 (-) and CXCL12 response (-), such as HL-CZ and K562 cells; the other is CXCR4 (+) and CXCL12 response (-), such as HL-60 and Raji cells; the rest is CXCR4 (+) and CXCL12 response (+), such as Jurkat and U937 cells. These results make us wonder that the leukemic cells could egress to PB from BM is due to destruction of homing process or the activation of mobilization process through CXCR4-CXCL12 axis dysfunction. Therefore,we will focus on evaluating the mechanism of CXCR4-CXCL12 axis dysfunction in the various leukemic cell lines and primary leukemic cells.
In this trial, HLA-A2+ patients with active AML are vaccinated with a peptide from the leukemia-associated antigen WT1 together with immunological adjuvants keyhole limpet hemocyanin (KLH) as T-helper protein and granulocyte macrophage colony stimulating factor (GM-CSF) 4 times bi-weekly, then monthly.
The purpose of this study is to evaluate the interest of maintenance treatment with interleukin-2 by randomizing the patients being not allogeneic transplanted in complete remission after induction and consolidation chemotherapy concerning the event free survival.
The purpose of this study is to evaluate the safety and the efficacy of cladribine, high-dose cytarabine and idarubicin in the treatment of patients with relapsed acute myeloid leukemia.
