Human γδ T-Cells: From Surface Receptors to the Therapy of High-Risk Leukemias

2018

γδ T lymphocytes are potent effector cells, capable of efficiently killing tumor and leukemia cells. Their activation is mediated by γδ T-cell receptor (TCR) and by activating receptors shared with NK cells (e.g., NKG2D and DNAM-1). γδ T-cell triggering occurs upon interaction with specific ligands, including phosphoantigens (for Vγ9Vδ2 TCR), MICA-B and UL16 binding protein (for NKG2D), and PVR and Nectin-2 (for DNAM-1). They also respond to cytokines undergoing proliferation and release of cytokines/chemokines. Although at the genomic level γδ T-cells have the potential of an extraordinary TCR diversification, in tissues they display a restricted repertoire. Recent studies have identified …

Hematopoietic Peripheral Circulating Blood Stem Cells As an Independent Marker of Good Transfusion Management in Patients with Beta-Thalassemia

2015

Abstract Aim Aim of the current study was to prospectively evaluate the potential role of peripheral circulating CD34+ stem cells as new independent marker of appropriate hemopoietic balance in patients with thalassemia major and intermedia. Materials and methods Peripheral blood samples from patients with thalassemia major (TM) and intermedia (TI) were drawn. Peripheral circulating CD34+ stem cells, CF-GEMM, CFU-GM and BFU-GM were assayed with monoclonal antibodies for CD34 and clonogenic tests, according to standard procedures and ISHAGE method (BD stem cell enumeration kit, Becton Dickinson; H4434, Stem Cell Technology). Demographic and clinical data were recorded from each enrolled subj…
