The NLRP3 inflammasome, IL-1β release and pyroptosis (cell lysis) have recently been proposed to be essential for the progression of urinary tract infection (UTI) and elimination of intracellular bacterial niches. However, the effects of IL-1R antagonist (IL-1RA) on immune responses during UTI, except for its ability to disrupt IL-1β signalling, are not well understood. The aim of this study was to investigate the role of IL-1RA in UPEC colonization of bladder epithelial cells and the subsequent host inflammatory response...

The immune profile associated with distinct clinical forms of tuberculosis (TB) has been extensively described for adult populations. Nevertheless, studies describing immune determinants of pulmonary or extrapulmonary TB (PTB or EPTB, respectively) in children are scarce. Here, we retrospectively assessed plasma levels of several mediators of inflammation in age and sex-matched children from South India presenting with PTB (n = 14) or EPTB (n = 22) as well as uninfected healthy controls (n = 19) to identify biomarkers that could accurately distinguish different TB clinical forms...

Responsiveness to the hepatitis B virus (HBV) vaccination in hemodialysis (HD) patients who had been exposed to the hepatitis E virus (HEV) and persistently generate antibodies against HEV remains unknown. Interferon (IFN)-λ3 positively correlates with the surface HBV antibodies (anti-HBs) in both healthy and HD subjects. We aimed to show whether HD patients differ in circulating IFN-λ3 and vaccine-induced anti-HBs titers concerning natural HEV immunization. HBV/HCV negative HD patients (31 HEV IgG positive, 45 HEV negative), HBV vaccinated and receiving booster doses as needed, had been tested for anti-HBs titers (CMIA) and IFN-λ3 concentrations (ELISA) in the blood collected before a dialysis session...

The intractability of Graves' disease (GD) and the severity of Hashimoto's disease (HD) vary among patients. Both genetic and environmental factors may be associated with their prognoses. To clarify the role of methylation of the IFNG gene in the pathogenesis and prognosis of (AITDs), we examined interferon gamma (IFNG) methylation levels at various CpG sites and genotyped IFNG +874 A/T and +2109 C/T polymorphisms. We analyzed methylation 59 patients with HD, 57 patients with GD and 26 healthy volunteers by pyrosequencing...

Measurement of cytokines in peripheral blood and bronchoalveolar lavage fluid (BALF) is a useful method to assess human immune responses in a large range of pulmonary diseases. One of the major pre-analytical challenges of cytokine analysis is the quality and stability of cytokines in the timeframe between sample collection and the separation of supernatant from cells. To evaluate if the method of storage may affect cytokine quantification, whole blood and BALF were collected, aliquoted, and left at room temperature (RT) to be processed at different time points...

Equine endometrosis (endometrial fibrosis) is a degenerative chronic process that occurs in the uterus of the mare and disturbs proper endometrial function. Fibrosis is attributed to excessive deposition of extracellular matrix (ECM) components. The turnover of ECM is mediated by matrix metallopeptidases (MMP). Previously, it was shown that cytokines modulate MMP expression in other tissues and may regulate fibrosis indirectly by attracting inflammatory cells to the site of inflammation and directly on various tissues...

Humans and animals frequently experience dysmetabolism induced by inflammation. Zinc-α2-glycoprotein (ZAG), a newly identified adipokine, is potentially involved in lipid metabolism. Our previous study revealed that the ZAG content increased after lipopolysaccharide (LPS) treatment. To clarify ZAG's possible effects on inflammatory responses and lipid metabolism, we used gene overexpression and knockout mice as models to investigate the function of ZAG during inflammation. The results showed that LPS increased plasma triglyceride, non-esterified fatty acid and hepatic triglyceride, while ZAG overexpression decreased these effects...

BACKGROUND: Cancer is a high-impact disease throughout the world. A negative correlation has been established between the development of cancer and the Th2 immune response. Infection by helminth parasites is characterized by the induction of a strong and long-lasting Th2 response. The aim of this work was to evaluate the effect of the immune response induced by the infection with the helminth Hymenolepis nana, on the tumorigenesis induced by dimethylbenz-anthracene (DMBA) in mice. METHODOLOGY: Four different groups of 14 female BALB/c mice were formed; Group A, dimethyl sulfoxide (DMSO) (vehicle) was administered cutaneously, Group B infected with H...

In the majority of myeloproliferative neoplasms (MPNs) patients, a point mutation, V617F has been found in Janus kinase 2 (JAK2) gene, and this JAK2 mutant provoked aberrant signaling pathway. In the current study, we found that suppressor of cytokine signaling proteins 3 (SOCS3) possessed the tumor suppressive activity against the JAK2 V617F mutant-provoked cellular transformation. The knockdown of SOCS3 increased the expression level of the JAK2 V617F mutant, which enhanced the activation of signaling mediators, including signal transducer and activator of transcription 3 and 5 (STAT3, STAT5) and extracellular signal-regulated kinase (ERK), and also increased of the proliferation rate and tumorigenesis activity of Ba/F3 cells expressing the JAK2 V617F mutant and erythropoietin receptor (EpoR)...

Pancreatic cancer is an aggressive disease with a poor prognosis for which current standard chemotherapeutic treatments offer little survival benefit. Receptor tyrosine kinases (RTK)s have garnered interest as therapeutic targets to augment or replace standard chemotherapeutic treatments because of their ability to promote cell growth, migration, and survival in various cancers. Met and Ron, which are homologous RTKs activated by the ligands hepatocyte growth factor (HGF) and macrophage stimulating protein (MSP), respectively, are over-activated and display synergistic malignant effects in several cancers...

Cystatins are natural inhibitors of cysteine peptidases. Recently, cystatins derived from plants, named phytocystatins, have been extensively studied. Among them, CsinCPI-2 proteins from Citrus sinensis were identified and recombinantly produced by our group. Thus, this study described the recombinant expression, purification, and inhibitory activity of this new phytocystatin against human cathepsins K and B and assessed the anti-inflammatory effect of CsinCPI-2 in vitro in mouse and in vivo in rats. In addition, the pro-osteogenic effect of CsinCPI-2 was investigated in vitro...

Although salivary gland cancers comprise only ∼3-6% of head and neck cancers, treatment options for patients with advanced-stage disease are limited. Because of their rarity, salivary gland malignancies are understudied compared to other exocrine tissue cancers. The comparative lack of progress in this cancer field is particularly evident when it comes to our incomplete understanding of the key molecular signals that are causal for the development and/or progression of salivary gland cancers. Using a novel conditional transgenic mouse (K5:RANKL), we demonstrate that Receptor Activator of NFkB Ligand (RANKL) targeted to cytokeratin 5-positive basal epithelial cells of the salivary gland causes aggressive tumorigenesis within a short period of RANKL exposure...
