Angiogenesis and lymphangiogenesis are important in the proliferation and survival of the malignant hematopoietic neoplasms, including non-Hodgkin's lymphomas (NHLs). Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) play an important role in the initiation of angiogenesis. Both VEGF and bFGF have been reported to have(More)
Multiple myeloma (MM) is a plasma cell malignancy characterised by bone marrow infiltration and the presence of a monoclonal protein in serum and/or urine. Interleukin-6 (IL-6) has been identified as one of the most important cytokines that contributes to myeloma cell survival and proliferation. Recent investigations suggest involvement of another cytokine,(More)
LYVE-1 (lymphatic endothelium hyaluronan receptor) has been identified as a powerful marker for lymphatic endothelium. Apart from lymphatic endothelium, LYVE-1 is expressed in normal liver blood sinusoids, spleen endothelium and activated tissue macrophages. LYVE-1 has not been detected in blood vascular endothelium with the exception of blood vessels in(More)
Pharmacokinetic studies of high-dose treosulfan were carried out in seven paediatric patients (age range: 2-15 years) undergoing treosulfan-based conditioning regimen prior to allogeneic haematopoietic SCT. Treosulfan was administered intravenously in a daily dose of 10, 12 or 14 g/m(2) within 2 h. Five out of seven patients received 12 g/m(2). The plasma(More)
The pathophysiology of Non-Hodgkin's lymphoma (NHL) is still unknown and clinical course is very unpredictable. Many cytokines, including interleukin-10 (IL-10), play a role in the perpetuation of this disease. The IL-10-producing capability has been found to be influenced by the IL-10 gene promoter polymorphisms. The aim of the present study was to assess(More)
Angiogenesis is important in development, maintenance and progression of haematological malignancies. Some clinical observations have indicated that in non-Hodgkin's lymphoma (nHL) tumour microvessel density (MVD) may correlate with tumour staging and outcome. The aim of the study was to examine relationship between MVD as a parameter of tumour angiogenesis(More)
Bone morphogenetic proteins (BMPs) are multifunctional cytokines which belong to transforming growth factor β (TGF β) superfamily. They regulate proliferation, differentiation, and apoptosis in a variety of cells including hematopoietic cells. BMPs act because of binding to two types of serine/threonine kinase receptors: BMP type I receptors (IA and IB) and(More)
Primary cutaneous T-cell lymphomas (CTCL) represent a heterogeneous group of neoplasms derived from skin-homing T cells. CTCL behave similarly to indolent B-cell lymphomas. There is increasing evidence that angiogenesis may be important in lymphoproliferative disorders. The aim of the study was to evaluate microvessel density (MVD) as a parameter of tumor(More)
Recent studies have suggested that Th17 cells may play a role in the pathogenesis of acute myeloid leukemia (AML). This subset of CD4+ cells is characterized by interleukin (IL)-17A and IL-17F production, which share strong homology, and surface expression of the IL-23 receptor (IL-23R). The present study aimed to determine the association between the(More)
Acute myeloid leukaemia (AML) is an aggressive malignancy with accumulation of blasts in bone marrow. Myeloblasts can entry into peripheral blood stream and secondary localize in extramedullary sites. The regulation of this process has not been clearly explained so far, but interactions between some chemokines and their specific receptors could be one of(More)
