title: Interleukin-7 receptor-alpha gene polymorphisms in bone marrow transplant recipients.
abstract: Graft-versus-host disease is the main complication after hematopoietic stem cells transplantation (HSCT). Non-HLA genotypes, such as cytokines, have been investigated for their potential roles in the occurrence and severity of GVHD as well as for their contribution to overall transplant-related mortality and survival. IL-7 which is secreted by bone marrow stromal cells plays an important role in the development and survival of T cells. Its effect is mediated via interleukin 7 receptor (IL7R). This study investigates the possible links between IL-7alphaR single nucleotide polymorphisms (+510 C/T, +1237 A/G, +2087 T/C and +3110A/G) and transplant outcomes among 116 recipients of HSCT. Genotypes were determined using polymerase chain reaction-sequence-specific primers. No significant differences were observed between the genotypic distributions of IL-7alphaR polymorphisms and incidence of acute or chronic graft versus host disease. Additional studies with larger sample are necessary to further define the influence of IL-7alphaR on the immune response after bone marrow transplantation.
