Among the complex network of inflammatory cells involved in the pathogenesis of rheumatoid arthritis (RA), Th17 cells have recently been identified as key cells in the promotion of autoimmune processes, and joint destruction. The IL-23/Th17 signalling pathway, consisting of IL-23/IL-23R, IL-17A and IL-17F encoding genes, represents a candidate way for RA(More)
PURPOSE 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(More)
Among cancers treated with allogeneic hematopoietic stem-cell transplantation (HSCT), some are sensitive to natural killer (NK) cell reactivity, described as the "missing self" recognition effect. However, this model disregarded the NK cell licensing effect, which highly increases the NK cell reactivity against tumor and is dependent on the coexpression of(More)
A total of 110 patients (71 adults and 39 children) who received allogeneic haematopoietic stem cell transplantation from HLA-matched sibling donors were studied for the incidence of acute graft-versus-host disease (aGvHD) in relation to IFN-gamma gene microsatellite polymorphism. A strong tendency was observed towards the lower incidence of grades II-IV(More)
Haematopoietic stem cell transplantation (HSCT) is a curative treatment of many hematological disorders. However, although significant advances have been made in donor-recipient matching or conditioning regimens, HSCT is associated with a risk of post transplant complications. Those include generation of toxic lesions, graft-versus-host-disease (GvHD) and(More)
The present study aimed to determine existing associations between single nucleotide polymorphisms within the promoters of interleukin (IL)-6 (-174 G/C) and IL-10 (-1082 G/A, -819 C/T, -592 C/A) genes and the outcome of allogeneic sibling hematopoietic stem cell transplantation. Ninety-three recipients and 74 donors were typed for IL-6 and IL-10 alleles by(More)
Genes involved in regulation of the nuclear factor - kappa B (NF-κB) pathway are suggested to play a role in the pathogenesis of acute myeloid leukaemia (AML). The present study aimed to assess the association between the NF-κB1, TRAF3 and TLRs genes single nucleotide polymorphisms (SNPs) and disease susceptibility as well as progression in patients with(More)
MNS16A is a functional polymorphic tandem repeat within the human telomerase reverse transcriptase (hTERT) gene. To investigate whether any of the MNS16A repeats represents a genetic risk factor for NHL susceptibility, progression of or response to therapy in 75 patients with non-Hodgkin's lymphomas (NHLs) and 126 healthy individuals were genotyped using(More)
Some cancers treated with allogeneic hematopoietic stem cell transplantation (HSCT) are sensitive to natural killer cell (NK) reactivity. NK function depends on activating and inhibitory receptors and is modified by NK education/licensing effect and mediated by coexpression of inhibitory killer-cell immunoglobulin-like receptor (KIR) and its corresponding(More)
