Maturation State and Function of Monocyte Derived Dendritic Cells in Liver Transplant Recipients
Background: Dendritic cells (DCs) are potent antigen presenting cells for triggering of the immune reaction post transplantation. These cells are centrally involved in the initiation of T cell-dependent immune responses. Objective: To compare the level of DC maturation and function in liver transplant recipients with healthy controls. Methods: In this study, twelve peripheral blood samples we...
متن کاملInterleukin-17 Gene Expression and Serum Levels in Acute Rejected and non-Rejected Liver Transplant Patients
Background: Interleukin-17 (IL-17), as a potent proinflammatory cytokine, has a critical role in post liver transplant outcomes. However, there is not much information about the effects of IL-17 cytokine on acute liver rejection. Objective: To evaluate the role of IL-17 in post-liver transplant acute rejection. Methods: Ninety seven adult liver transplant patients who enrolled in this cross sec...
متن کاملInterleukin (IL)-1 promotes allogeneic T cell intimal infiltration and IL-17 production in a model of human artery rejection
Interleukin (IL) 1alpha produced by human endothelial cells (ECs), in response to tumor necrosis factor (TNF) or to co-culture with allogeneic T cells in a TNF-dependent manner, can augment the release of cytokines from alloreactive memory T cells in vitro. In a human-mouse chimeric model of artery allograft rejection, ECs lining the transplanted human arteries express IL-1alpha, and blocking I...
متن کاملIL-6 and TNF- Synergistically Inhibit Allograft Acceptance
Previous studies suggested that activation of the innate immune system impairs the induction of transplantation tolerance, but the responsible inflammatory mediators have not been identified. In this study, we examined whether IL-6 and TNFpromote resistance to transplantation tolerance. Using a highly immunogenic murine skin allograft model, we found that the absence of both IL-6 and TNFin the ...
متن کاملInterleukin-6 expression after renal transplantation.
BACKGROUND Interleukin-6 (IL-6) is an inflammatory cytokine that plays a role in transplant rejection. We tested the hypothesis that IL-6 levels in serum or urine could be of value in predicting acute and chronic allograft rejection. Furthermore, we examined whether or not such levels reflected IL-6 expression in the kidney. METHODS We measured IL-6 and IL-6 soluble receptor (IL-6sR) in serum...
