Abstract
Acute leukemias (both myeloid and lymphoblastic) are a group of diseases for which each year more successful therapies are implemented. However, in a subset of cases the overall survival (OS) is still exceptionally low due to the infiltration of leukemic cells in the central nervous system (CNS) and the subsequent formation of brain tumors. The CNS involvement is more common in acute lymphocytic leukemia (ALL), than in adult acute myeloid leukemia (AML), although the rates for the second case might be underestimated. The main reasons for CNS invasion are related to the expression of specific adhesion molecules (VLA-4, ICAM-1, VCAM, L-selectin, PECAM-1, CD18, LFA-1, CD58, CD44, CXCL12) by a subpopulation of leukemic cells, called “sticky cells” which have the ability to interact and adhere to endothelial cells. Moreover, the microenvironment becomes hypoxic and together with secretion of VEGF-A by ALL or AML cells the permeability of vasculature in the bone marrow increases, coupled with the disruption of blood brain barrier. There is a single subpopulation of leukemia cells, called leukemia stem cells (LSCs) that is able to resist in the new microenvironment due to its high adaptability. The LCSs enter into the arachnoid, migrate, and intensively proliferate in cerebrospinal fluid (CSF) and consequently infiltrate perivascular spaces and brain parenchyma. Moreover, the CNS is an immune privileged site that also protects leukemic cells from chemotherapy. CD56/NCAM is the most important surface molecule often overexpressed by leukemic stem cells that offers them the ability to infiltrate in the CNS. Although asymptomatic or with unspecific symptoms, CNS leukemia should be assessed in both AML/ALL patients, through a combination of flow cytometry and cytological analysis of CSF. Intrathecal therapy (ITT) is a preventive measure for CNS involvement in AML and ALL, still much research is needed in finding the appropriate target that would dramatically lower CNS involvement in acute leukemia.

Abstract
L-selectin is a protein with potential importance for numerous diseases and clinical disorders. In this paper, we present a new aptamer-based luminescent assay developed to detect L-selectin. The sensing system working principle is based on Förster Resonance Energy Transfer (FRET) from a donor terbium complex (TbC) to an acceptor cyanine dye (Cy5). In the present approach, the biotinylated aptamer is combined with Cy5-labelled streptavidin (Cy5-Strep) to yield an aptamer-based acceptor construct (Apta-Cy5-Strep), while L-selectin is conjugated using luminescent TbC. Upon aptamer binding to the TbC-labelled L-selectin (L-selectin-TbC), permanent donor-acceptor proximity is established which allows for radiationless energy transfer to occur. However, when unlabelled L-selectin is added, it competes with the L-selectin-TbC and the FRET signal decreases as the L-selectin concentration increases. FRET from the TbC to Cy5 was observed with time-gated time-resolved luminescence spectroscopy. A significant change in the corrected luminescence signal was observed in the dynamic range of 10-500 ng/mL L-selectin, the concentration range relevant for accelerated cognitive decline of Alzheimer's disease, with a limit of detection (LOD) equal to 10 ng/mL. The aptasensor-based assay is homogeneous and can be realized within one hour. Therefore, this method has the potential to become an alternative to tedious heterogeneous analytical methods, e.g. based on enzyme-linked immunosorbent assay (ELISA).

Abstract
OBJECTIVES An aberrant pattern of expression of L-selectin and intercellular adhesion molecule 1 (ICAM1) may characterise CD34+ blast cells in myelodysplastic syndromes (MDS) and secondary acute myeloid leukaemia (sAML). METHODS In a three-colour flow cytometric assay, we evaluated the expression of L-selectin and ICAM1 on CD34+ blast cells from the bone marrow (BM) of 66 MDS patients; for the purpose of comparison CD34+ blast cells of 18 sAML and CD34+ stem cells of 17 normal donors were also analysed. RESULTS The ratio of L-selectin/ICAM1 expression was identified as a parameter correlated with the percentage of BM blast infiltration and the time to leukaemic progression among MDS patients. In fact, the values of L-selectin/ICAM1 ratio were inversely correlated with the BM blast infiltration (r = -0.34, P = 0.004). Furthermore, MDS patients with a baseline ratio <1 had a higher leukaemic progression rate (41% vs. 19%, P = 0.008); the actuarial risk of disease progression for this subgroup of MDS patients was also higher (64% vs. 11% at 2 yr, P = 0.002). Furthermore, in two patients a decrease of the ratio was observed when overt leukaemic transformation occurred; conversely, restoration of a normal ratio was observed in two patients after a chemotherapy-induced remission. CONCLUSION (i) L-selectin is defective in the stem cell compartment of MDS and sAML, whereas ICAM1 is overexpressed; (ii) the ratio of their expression has a prognostic role; and (iii) a ratio <1 significantly predicts progression to overt leukaemia in MDS patients.

Abstract
OBJECTIVES Hemopoietic cytokines regulate hemopoietic cell functions via specific cell surface receptors. There is evidence to suggest, that those receptors (R) could play a role in leukemia with respect to cell differentiations and its regulation, prognosis, and pathobiology. Knowledge of individual cytokine receptor (CKR) profiles could provide new discoveries about CKR-supported therapeutic considerations. METHODS We have studied the expression of CKR on mononuclear bone marrow (BM) cells of 89 patients with acute myeloid leukemia (AML) at first diagnosis, three patients at relapse or with persisting AML and eight healthy probands by fluorescence-activated cell sorting (FACS) analysis using directly fluorescein-conjugated antibodies: CD114 (hG-CSF-R), CD116 (hGM-CSF-R), CD117 (hSCF-R), CD123 (hIL-3-R), CD130 (gp130subunit), CD135 (hFL-R). A case was defined as positive, if more than 20% of the cells expressed the regarding CKR. RESULTS All investigated CKR were more frequently expressed in AML-samples than in healthy BM-samples, except CD130, which was only expressed on 5-6% of AML-blasts in all and with only one healthy BM-sample being CD130(+). Within the French-American-British (FAB) types we observed a maturation- and lineage (granulocytic/monocytic)-committed expression profile. Monocytic subtypes (FAB-type M4/M5) showed significantly more GM-CSF-R(+) (P = 0.001) and FL-R(+) (P = 0.001) and significantly less stem cell factor-R (SCF-R(+)) (P = 0.02) cases. Highest proportions of G-CSF-R(+) blasts were observed in FAB-type M3. In undifferentiated leukemias (FAB-type M1, M2) high amounts of SCF-R(+), IL-3-R(+), and FL-R(+) blasts could be detected. FL-R was the only CKR, which was positive in FAB-type M0 (n = 2). No differences in CKR-expression were detected between primary (p) and secondary (s). Separating our patient cohorts in cytogenetic risk groups we could detect a significant higher proportion of G-CSF-R(+) blasts in the cytogenetic good risk group than in the bad risk group (P = 0.027), but G-CSF-R-expression did not correlate with remission-rate or relapse-free survival probability of the patients. For clinical evaluation only patients treated by the AML-CG-protocol, were included (n = 53). There were no differences of CKR-expression in the responder and non-responder group, however, significant lower relapse-free survival probabilities for patients with more than 85.5% FL-R(+) (P = 0.001) and more than 45.5% SCF-R(+) blasts were found (P = 0.02). Patients with more than 32.5% IL-3-R(+) cells also showed a tendency to a lower relapse-free survival probability (P = 0.26), whereas patients with more than 33% GM-CSF-R(+) (P = 0.06) and patients with more than 52% G-CSF-R(+) (P = 0.175) blasts tended to have a higher relapse-free survival probability. CONCLUSION We can conclude, that CKR-expression in AML is maturation- and lineage-committed and the proportions of especially early acting CKR have influence on relapse-free survival probability of AML-patients, independently of the karyotype. With respect to the individual CKR status the benefit of cytokines as priming agents, as agents to treat neutropenia or to influence the metabolism of chemotherapy can be discussed under new points of view.
