Abstract
The present study was conducted to investigate the relationship between single nucleotide polymorphisms (SNPs) in TLR10 and the clinical outcomes of renal transplant patients who took tacrolimus (TAC) as an immunosuppressant, and further confirmed the results in liver transplant patients. A total of 172 renal transplant patients and 145 pairs of liver transplant recipients and donors were included. Nineteen SNPs of TLR10 gene were detected by matrix-assisted laser desorption ionization-time-of-flight-mass spectrometry (MALDI-TOF-MS). The associations of recipient SNPs with TAC-related clinical outcomes were explored in renal transplant recipients. The relationship between recipient and donor SNPs and the clinical outcomes of liver transplant patients were investigated to confirm the results. Three SNPs (rs28393318, rs11466655 and rs11096957) in renal transplant recipients were found to influence the graft function after transplantation (P = 0.00003, 0.001 and 0.000003, respectively). The recipient rs11096957 was also found to affect the TBil, and DBil levels in liver transplant recipients (P = 0.001 and 0.002). In this study, we identified significant association signals from TLR10 polymorphisms with clinical outcomes in TAC-treated transplant patients in a Chinese Han-based sample. We provide some evidence for the effect between rs11096957 in TLR10 gene on the graft functions in both renal and liver transplantation.

Abstract
Toll-like receptors (TLRs) have important role in transplant outcomes by activating the innate immune system and production of pro-inflammatory cytokines, leading to graft rejection. We assessed the expression level of TL2 and TLR4 in acute rejection (AR) on the 1st and 7th-day post-transplantation. TLR2 and TLR4 expressions were evaluated by real-time PCR in both the AR group (n = 50) and non-AR (n = 50), compared with the control group. Also, the correlation of the expression levels of TLRs between both the 1st and 7th day was analyzed. ROC curve analysis was used to determine the cut-off value for TLRs expression. TLR4 mRNA expression was significantly up-regulated in AR patients vs. the controls on the 1st day (p ≤ 0.05) and it was down-regulated in non-AR vs. controls on the 1st day (p ≤ 0.05). Also, TLR4 expression had decreased in both AR and non-AR groups vs. control on the 7th day (p ≤ 0.05). Both TLR2 and TLR4 expression in comparison to non-AR had increased in the AR group on the 7th day (p ≤ 0.05). TLR2 expression positively correlated between 1st and 7th day in AR (r = 0.3, (p ≤ 0.05) and non-AR group (r = 0.2, p ≤ 0.05). ROC curve analysis showed a cut-off value of TLR2 up to 0.98 with sensitivity 71.05 (95%CI = 54.1-84.6) and specificity 63.27 (95%CI = 48.3-76.6) that could distinguish between AR and non-AR group (p ≤ 0.05). The data support that both TLR2 and TLR4 expression have an effective role in AR after liver transplantation and could be used as possible biomarkers for AR to choose better therapeutic strategies based on immunological aspects.

Abstract
Allograft inflammatory factor-1 (AIF-1) is a cytoplasmic protein that is encoded by the AIF1 gene. The main functions of AIF-1 are the activation of macrophages and enhancing the production of pro-inflammatory cytokines. To date, three different AIF-1 isoforms have been identified. In this study, we examined the expression of AIF-1 isoforms on the level of mRNA, and we compared the percentage of AIF-1-positive white blood cells (WBCs) in blood and AIF-1/CD68 cells in the synovial membranes in patients with rheumatoid arthritis (RA) and osteoarthritis (OA). We examined 15 patients with RA and 15 patients with OA who had previously undergone knee arthroplasty. Peripheral blood and synovial membranes (SMs) were collected from these patients during knee arthroplasty. We identified three AIF-1 mRNA expression variants in peripheral mononuclear cells (PBMCs) and SMs from patients in both groups. Spearman’s rank correlation coefficient tests showed strong, positive, and significant correlations between the three AIF-1 mRNA expression variants in PBMCs and/or SMs in patients with RA and OA. There were no statistically significant correlations for any of the AIF-1 mRNA expression variants between PBMCs and SMs in patients with RA and OA. We observed a statistically significant increased percentage of AIF-1-positive cells in patients with RA in comparison to patients with OA. The percentage of AIF-1-positive cells in the blood of patients with RA and OA was 1.35 ± 0.81% and 0.71 ± 0.25% (p < 0.01), respectively, whereas the percentage of AIF-1/CD68-positive WBC cells in the SMs was 24.05 ± 7.17% and 4.78 ± 1.52% (p < 0.001), respectively. In conclusion, three AIF-1 mRNA expression variants occurred in PBMCs and SM cells in patients with RA and OA. The AIF-1 mRNA expression levels of the variants correlated with each other in PBMCs and SM cells, but there were no statistically significant correlations for AIF-1 mRNA expression variants between PBMCs and SM cells in patients with RA and OA. Both in the blood and SMs, we observed an increased percentage of AIF-1-positive cells in patients with RA in comparison to patients with OA. The above results suggested that AIF-1 was the cytokine involved in the pathogenesis of RA. The precise knowledge of the role of AIF-1 in RA pathogenesis and the development of inflammatory response requires further investigations.

Abstract
Allograft inflammatory factor-1 (AIF-1) is a 17 kDa calcium-binding protein produced by monocytes, macrophages, and lymphocytes; its synthesis is induced by INF-γ. The AIF-1 gene is located in the major histocompatibility complex (MHC) class III region on chromosome 6p21.3, surrounded by surface glycoprotein genes and complement cascade protein genes as well as TNF-α, TNF-β, and NF-κB genes. Increased expression of AIF-1 was observed in several diseases, including endometriosis, breast cancer, atherosclerosis, rheumatoid arthritis, and fibrosis. In this review, we summarise the role of AIF-1 in allograft rejection and the pathogenesis of diseases.

Abstract
Allograft inflammatory factor-1 (AIF-1) plays an important role in various inflammatory conditions. Our previous study demonstrated that AIF-1 was over-expressed in the liver of BALB/c mice infected with Schistosoma japonicum and played significant role in the pathogenesis of schistosomiasis. The aim of this study was to focus on the effect of AIF-1 treatment on liver fibrosis and necrosis of BALB/c mice infected with S. japonicum. Seventy-two BALB/c mice were infected with cercariae of S. japonicum and then divided into three groups: AIF-1-treated group, saline-treated group, and control group. The vital signs, liver function, egg load, and hepatic pathological changes of the mice were assessed, and the levels of AIF-1 and TNF-α in the liver and spleen were measured at 5, 8, and 14 weeks postinfection. The treatment of AIF-1 on the mice infected with S. japonicum suppressed the expression of TNF-α and increased the effectiveness of AIF-1 in the liver and spleen at 14 weeks postinfection. Histopathological analysis and Masson trichrome staining for the liver tissues showed that the liver fibrosis and necrosis were alleviated previously compared with other infected mice at 14 weeks postinfection. The treatment of AIF-1 on the mice infected with S. japonicum can alleviate hepatic fibrosis and necrosis which indicate that AIF-1 use may prevent and cure the liver fibrosis.

Abstract
Cellular rejection after renal transplantation, in general, occurs as a result of an interaction between immunologic processes that maintain graft tolerance versus allograft rejection. A potential mechanism that triggers such processes might be through the activation of the innate immune response initiated during organ procurement and ischemia/reperfusion injury, contributing to delayed graft function or graft dysfunction. Our goal was to test the impact of molecular markers that have key roles in innate immunity such as cytokines, Toll-like receptors (TLRs), and allograft inflammatory factor-1 (AIF- 1) at early times after transplantation. Blood samples from a total of 90 patients who received kidney transplants were included in this study. Three samples from each patient at different time intervals (pretransplantation, day 3, and day 6 after transplantation) were tested using a quantitative reverse transcriptase polymerase chain reaction. The mRNA transcripts were tested in association with glomerular filtration rates (GFR) as a measure of allograft function. Surgical samples obtained from transplant nephrectomy were used in a tissue array for immunohistochemistry testing. In peripheral blood mononuclear cells, the mean ± standard error of mean (SEM) for interleukin 18 (IL-18), and IL-10 mRNA expression were increased and interferon-γ was decreased in association with high GFR post-transplantation as compared with the pretransplantation expression levels. The mean ± SEM for expression level of AIF-1 was increased 1.5-fold and for TLR-2 and TLR-4 were increased 1.2 to 1.4-fold in samples obtained on day 6 post-transplantation in association with low GFR (P < .05). In neutrophils, the mean ± SEM levels of TLR-2 mRNA was increased 2-fold on day 6 in association with high GFR (P < .005), but was reduced 2.8-fold in association with low GFR (P < .002). In conclusion, the mRNA profiles of biomarkers presented here appeared to be informative for prediction of allograft status and outcome.

Abstract
BACKGROUND Evidence suggests that injury-induced activation of the recipient's innate immune response determines the outcome of allograft transplantation. The mechanism responsible for the induction of such innate immune response is not clear yet. We hypothesized that in cardiac transplantation settings, the initial myocardial ischemia and postischemia graft reperfusion may release allograft inflammatory factor (AIF) 1, causing Toll-like receptor (TLR)-mediated activation of macrophages and dendritic cells, leading to the production of cytokines and the activation of adaptive alloimmunity. Therefore, our goal was to validate the presence of these biomarkers in the peripheral blood and biopsy specimens of patients presenting allograft rejection. METHODS We studied 90 peripheral blood and 30 endomyocardial biopsy specimens from patients who had undergone cardiac transplantation. Specimens were tested by quantitative reverse-transcription polymerase chain reaction to determine TLR-2 and -4 and AIF-1 expression levels, correlating with clinical rejection grades. The group differences for mRNA transcript levels between the rejection grades were determined by 1-way analysis of variance. The level of significance was set at P < .05 for comparison between the groups. RESULTS The mean ± SEM level of TLR-2 mRNA expression was increased 1.7-fold in monocytes (P < .05) and 4.2-fold in biopsy samples from groups with grade 3A compared with grade 1A or grade 0 rejection (P < .0001). AIF-1 expression was increased 2.4-fold in monocytes (P < .05) and 4.2-fold in biopsy samples comparing grade 3A versus 1A rejections. The TLR-4 mRNA expression was also increased in the group with 3A rejections; however, the difference was only significant in biopsy specimens (P < .0001). CONCLUSIONS Our data demonstrated that expression profiles of AIF-1 and TLR-2 correlated with biopsy-proven allograft rejection in both peripheral blood and local tissue, suggesting their potential as diagnostic biomarkers for early detection of allograft rejection.
