miR-223 in exosomes from bone marrow mesenchymal stem cells ameliorates rheumatoid arthritis via downregulation of NLRP3 expression in macrophages.Rheumatoid arthritis (RA) is an autoimmune disease with major clinical manifestations of human limb joint invasion, joint synovitis, and symmetrical lesions. In recent years, bone marrow mesenchymal stem cells (BMSCs) have been found to have low immunogenicity and immunomodulatory effects, which can regulate other types of cells through exosomes. However, the effect of BMSCs on immune response in the progression of RA has not been fully elucidated.

Biomarkers of acute kidney injury after pediatric cardiac surgery: a meta-analysis of diagnostic test accuracy.Acute kidney injury (AKI) occurs frequently after cardiac surgery in children. Although current diagnostic criteria rely on serum creatinine and urine output, changes occur only after considerable loss of kidney function. This meta-analysis aimed to synthesize the knowledge on novel biomarkers and compare their ability to predict AKI. PubMed/MEDLINE, Embase, Scopus, and reference lists were searched for relevant studies published by March 2021. Diagnostic accuracy parameters were extracted and analyzed using hierarchical summary receiver operating characteristic (HSROC) method. Pooled estimates of the area under the curve (AUC) were calculated using conventional random-effects meta-analysis. Fifty-six articles investigating 49 biomarkers in 8617 participants fulfilled our eligibility criteria. Data from 37 studies were available for meta-analysis. Of the 10 biomarkers suitable for HSROC analysis, urinary neutrophil gelatinase-associated lipocalin (uNGAL) to creatinine (Cr) ratio yielded the highest diagnostic odds ratio (91.0, 95% CI 90.1-91.9), with a sensitivity of 91.3% (95% CI 91.2-91.3%) and a specificity of 89.7% (95% CI 89.6-89.7%). These results were confirmed in pooled AUC analysis, as uNGAL-to-Cr ratio and uNGAL were the only elaborately studied biomarkers (>â5 observations) with pooled AUCsââ¥â0.800. Liver fatty acid-binding protein (L-FABP), serum cystatin C (sCysC), serum NGAL (sNGAL), and interleukin-18 (IL-18) all had AUCsââ¥â0.700.Conclusion: A variety of biomarkers have been proposed as predictors of cardiac surgery-associated AKI in children, of which uNGAL was the most prominent with excellent diagnostic qualities. However, more consolidatory evidence will be required before these novel biomarkers may eventually help realize precision medicine in AKI management. What is Known: â¢ Acute kidney injury (AKI) occurs in about 30-60% of children undergoing cardiac surgery and is associated with increased in-hospital mortality and adverse short-term outcomes.Â However, in current clinical practice, AKI definitions and detection often rely on changes in serum creatinine and urine output, which are late and insensitive markers of kidney injury. â¢ Although various novel biomarkers have been studied for the diagnosis of AKI in children after cardiac surgery, it remains unclear how these compare to one another in terms of diagnostic accuracy. What is New: â¢ Pooled analyses suggest that for the diagnosis of AKI in children who underwent cardiac surgery, NGAL is the most accurate among the most frequently studied biomarkers. â¢ A number of other promising biomarkers have been reported, although they will require further research into their diagnostic accuracy and clinical applicability.

Harnessing self-assembling peptide nanofibers toprime robust tumor-specific CD8 T cell responses in mice.Induction of tumor-specific CD8Â +Â T cell responses is known as a major challenge for cancer vaccine development; here we presented a strategy to improve peptide nanofibers-mounted antitumor immune responses. To this end, peptide nanofibers bearing class I (Kb)-restricted epitope (Epi-Nano) were formulated with polyethylene imine backbone (Epi-Nano-PEI), and characterized using morphological and physicochemicalcharacterizationtechniques. Nanofibers were studied in terms of their uptake by antigen-presenting cells (APCs), antigen cross-presentation capacity, and cytotoxic activity. Furthermore, nanofibers were assessed by their potency to induce NLRP3 inflammasome-related cytokines and factors. Finally, the ability of nanofibers to induce tumor-specific CD8 T cells and tumor protection were investigated in tumor-bearing mice. The formulation of Epi-Nano with PEI led to the formation of short strand nanofibers with a positive surface charge, a low critical aggregation concentration (CAC), and an increased resistancetoproteolytic degradation. Epi-Nano-PEI was significantly taken up more efficiently by antigen-presenting cells (APCs), and was more potent in cross-presentation when compared to Epi-Nano. Moreover, Epi-Nano-PEI, in comparison to Epi-Nano, efficiently up-regulated the expression of NLRP3, caspase-1, IL-1b, IL18 and IL-6. Cell viability analysis showed that formulation of PEI with Epi-Nano not only abolished its cytotoxic activity, but surprisingly induced macrophage proliferation. Furthermore, it demonstrated that Epi-Nano-PEI triggered robust antigen-specific CD8 T cell responses, and induced maximum antitumor response (tumor growth inhibition and prolonged survival) in tumor-bearing mice that were significantly higher compared to Epi-Nano. Taken together, the formulation of Epi-Nano with PEI is suggested as a promising strategy to improve nanofibers-mounted antitumor immune response.

Quantile-Specific Heritability of Inflammatory and Oxidative Stress Biomarkers Linked to Cardiovascular Disease.Heritability ( , the proportion of the phenotypic variance attributable to additive genetic effects) is traditionally assumed to be constant throughout the distribution of the phenotype. However, the heritabilities of circulating C-reactive protein, interleukin-6, plasminogen activator inhibitor type-1 (PAI-1), and monocyte chemoattractant protein-1 (MCP-1) concentrations depend upon whether the phenotype is high or low relative to their distributions (quantile-dependent expressivity), which may account for apparent gene-environment interactions. Whether the heritabilities of other inflammatory biomarkers linked to cardiovascular disease are quantile-dependent remain to be determined.

ROS-NLRP3 signaling pathway induces sterile inflammation after thulium laser resection of the prostate.The sterile inflammation (SI) of the urinary tract is a common problem requiring serious consideration after prostatectomy. This study mainly focuses on the role of the reactive oxygen species-NLR family, pyrin domain-containing 3 (ROS-NLRP3) signaling pathway in SI after thulium laser resection of the prostate (TmLRP). Urinary cytokines wereÂ determined in patients who received TmLRP, and heat shock protein 70 (HSP70) was detected in the resected tissues. The involvement of ROS signaling in HSP70-induced inflammation was explored in THP-1 cells with or without N-acetyl- l-cysteine (NAC) pretreatment. The function of NLRP3 and Caspase-1 was determined by Western blot analysis, enzyme-linked immunosorbent assay (ELISA), and polymerase chain reaction. These phenomena and mechanisms wereÂ verified by the beagle modelsÂ that received TmLRP. Clinical urine samples after TmLRP showed high expression of inflammatory factors and peaked 3-5 days after surgery. The high expression of HSP70 in the resected tissues was observed. After HSP70 stimulation, the expression of ROS, NLRP3, Caspase-1, and interleukin-18 (IL-18) increased significantly and could be reduced by ROS inhibitor NAC. The expression of IL-1Î² and IL-18 could be inhibited by NLRP3 or Caspase-1 inhibitors. In beagle models that received TmLRP, HSP70, NLRP3, Caspase-1, IL-1Î², and IL-18 were highly expressed in the wound tissue or urine, and could also be reduced by NAC pretreatment. Activation of the ROS-NLRP3 signaling pathway induces SI in the wound after prostatectomy. Inhibition of this pathway may be effective for clinical prevention and treatment of SI and related complications after prostatectomy.

Plasma neutrophil gelatinase-associated lipocalin and Interleukin-18 as predictors of acute kidney injury in renal transplant recipients: A pilot study.Urine neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL- 18) have shown promise for predicting renal graft recovery. However, urinary flow rate variations may cause variable biomarker dilution. Plasma NGAL and IL-18 may form a biomarker panel that may help predict delayed graft function and slow graft function (SGF) in renal transplant recipients within the first two postoperative days earlier than serum creatinine. There are only a few studies in the literature using plasma NGAL for predicting renal graft recovery. Hence, we planned this study. This observational single-center, prospective cohort study was conducted in renal transplant recipients above 18 years of age. In 22 consecutive renal transplant recipients, we collected ethylenediaminetetraacetic acid-plasma samples 1 h before surgery and subsequently at 6 h, 24 h, and 48 h after surgery for NGAL and IL-18 by sandwich enzyme-linked immuno-sorbent assay technique. Serum creatinine was measured as a part of routine transplant protocol. In renal transplant recipients, neither serum levels of NGAL and IL-18 nor their trends could reliably predict SGF. The only significant correlation existed between serum creatinine at day 2 and IL-18 at day 2 with P = 0.023. Serum NGAL did not correlate with serum creatinine in this setting of renal transplantation. Patients with immediate graft function had a greater percentage decrease of creatinine at day 1 and day 2 (P = 0.002 and 0.001) The percentage change in IL-18 at 24 h and 48 h after transplant from baseline could predict the occurrence of early graft loss (EGL) (P = 0.05, 0.04). The cutoffs were -4.12% at day 1 and +3.39% at day 2 with area under receiver operator characteristics of 0.82 and 0.83, respectively. The percentage change in IL-18 may be a useful marker of EGL in renal transplant recipients. Serum NGAL and creatinine were not able to predict EGL.

Using urinary Interleukin-18 as a potential marker for early detection of acute kidney injury in intensive care unit.Acute kidney injury (AKI) is a potentially life-threatening condition. The injury involves the generation of inflammatory mediators which contribute to the recruitment of leukocytes to the site of inflammation. As those inflammatory mediators are secreted directly into the urine, their detection in urine could serve as potential biomarkers for the diagnosis of early kidney injury. This is a prospective cross-sectional descriptive study. Urinary samples were collected from 170 subjects who were admitted to intensive care unit (ICU) at Alkafeel Super Speciality Hospital from September 2017 to June 2018. They were tested for urinary interleukin-18 (IL-18). Among 98 patients, 20 were excluded depending on exclusion criteria. Seventy-two cases in the control group were included. The urine samples were collected at 24, 48, and 72 h after admission to ICU. AKI was diagnosed according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria. The incidence rate of AKI among 78 patients who were admitted to ICU was 38.46%. Most of the patients with AKI belonged to stage 1 (80%) based on KDIGO guidelines2012. Urinary IL-18 levels were significantly higher (P <0.0001) in the AKI group in comparison with the non-AKI group. The result of receiver operating characteristic analysis showed that the higher area under the curve for urinary IL-18 was 0.946 measured at 24 h before development of AKI (P <0.000), with 87.5% sensitivity and 94.4% specificity. In addition, there was no significant difference of urinary IL-18 levels between the different causes of AKI. The results of the study indicate that urinary IL-18 has an excellent performance in predicting AKI in ICU patients.
