Abstract
The activating cytotoxicity receptor NKG2D binds to stress-regulated molecules encoded by the major histocompatibility complex class I chain-related (MIC) and UL-16-binding protein (ULBP)/retinoic acid early transcript (RAET) gene family. To assess whether acute allograft rejection leads to an induction of these inducible ligands and their receptor NKG2D, we examined the mRNA profiles in kidney transplant biopsies. Expression levels were correlated with the incidence of acute rejection (aRx) episodes and chronic allograft nephropathy (CAN) proven by histology. Whereas MICA, ULBP1/3 and RAET1-E did not display heightened gene expression, elevated levels of NKG2D mRNA could be associated with aRx (p < 0.001). Immunohistology of kidney biopsies diagnosed with aRx revealed NKG2D+ cells in tubulointerstitial areas positive for CD8+ cells. Most importantly, elevated levels of NKG2D mRNA were associated with restricted long-term graft function assessed by the glomerular filtration rate at 6, 12 and 18 months posttransplantation. Induced NKG2D mRNA expression was still observable in biopsies diagnosed with CAN (p < 0.001), demonstrating a higher sensitivity and specificity compared to CD3, granzyme B and granulysin mRNA measurement. Significant elevated levels of NKG2D mRNA could be further detected in urine sediment prior to aRx, suggesting this receptor as a new candidate marker for the diagnosis of acute and chronic allograft rejection.

Abstract
Despite advances in immunosuppression in past decades, allograft rejection remains the main reason for kidney graft failure. Recently, despite great improvements in understanding of molecular basis of allograft rejections, renal histology remains the primary method to monitor the onset of graft rejection. The aim of the present study was to ascertain whether cytokine and chemokine expression profiles in kidney allografts contributed to the diagnosis of graft dysfunction. We analyzed mRNA expression in 174 kidney graft biopsies for the following cytokines: TGF-beta1, TNF-alpha, IL-10, and chemokine RANTES. Based on the expression levels obtained by real-time RT-PCR, we correlated data with the results of morphologic examinations. All tested cytokines and chemokines were upregulated (P < .001) during acute rejection compared to nonrejecting controls. Upregulation was also found in chronic allograft nephropathy (CAN) group for TGF-beta1, IL-10 (P < .001), TNF-alpha, and RANTES (P < .01). Upregulated expression of IL-10 (P < .001), TGF-beta1, (P < .01) and RANTES (P < .05) showed borderline changes. Higher expression levels (P < .001) of TGF-beta1 and IL-10 were also found during ATN. IL-10 was upregulated (P < .01) in specimens with recurrent glomerulonephritis. Weakly increased (P < .05) expressions of TGF-beta1 were found during CsA toxicity. Distinctive expression levels between acute rejection and CAN were only found for IL-10 (P < .01). TNF-alpha showed a different expression profile in acute rejection versus ATN (P < .001). These findings suggest that distinct cytokine and chemokine expression profiles in grafts may contribute to the diagnosis for and elucidation of the immunopathologic process during graft dysfunction.

Abstract
Posttransplantation alloantigen-dependent and alloantigen-independent processes are both mediated by cytokines and chemokines. Recently cytokines and chemokines, as well as their receptors, have been shown to be highly polymorphic. The cytokine and chemokine gene polymorphisms are associated with variable production, activity, expression, or ligand-receptor affinity. The aim of our study was to analyze the relation between selected cytokine and chemokine gene polymorphisms in kidney donors and recipients as a function of donor-recipient match and posttransplantation outcome. Polymorphisms transforming growth factor-beta (TGF-beta); tumor necrosis factor-alpha (TNF-alpha); interleukin (IL)-6, and IL-10; monocyte chemoattractant protein-1 (MCP-1); and RANTES (regulated upon activation, normal T-cell expressed and secreted) genes were determined using DNA polymerase chain reaction technology in 268 healthy volunteers, 345 kidney transplant recipients (1997 to 1999), and 298 cadaveric donors. Patients were followed up for 4 to 6 years. The distribution of alleles of selected genes was identical in control subjects, cadaveric donors, and recipients. Low TGF-beta production in both the donor and recipient genotypes was associated with risk for early rejection (6 months) and worse graft function at 4 years. The only tendency for worse graft outcome was observed among donor-recipient combinations mismatched for TGF-beta genotype. Genetic determination of TNF-alpha and IL-10 production was associated with delayed graft function and rejection. IL-6 gene polymorphisms had no effect on the incidence of early acute rejections, but was associated with worse 5-year outcomes. Determinations of MCP-1 overproduction and RANTES-109 TT allele were associated with significant deterioration of graft function. Our data support the hypothesis that the strength of the alloimmune response after transplantation is in part genetically determined. Donor-recipient matching of cytokine gene polymorphisms has a marginal effect.
