Airway and skeletal diseases are prominent among agriculture workers. Repetitive inhalant exposures to agriculture organic dust extract (ODE) induces bone deterioration in mice; yet the mechanisms responsible for connecting the lung-bone inflammatory axis remain unclear. We hypothesized that the interleukin (IL)-6 effector response regulates bone deterioration following inhalant ODE exposures. Using an established intranasal inhalation exposure model, wild-type (WT) and IL-6 knockout (KO) mice were treated daily with ODE or saline for 3 weeks...

The oligoadenylate synthetase (OAS) is well known as an antiviral factor against the flavivirus infection in mammals. It is known that the oligoadenylate synthetase-like (ChOAS-L) gene is only present in the chicken genome. It has been shown in the previous report that the ChOAS-L possesses enzymatic activity to convert ATP into 2'-5'-linked oligoadenylates and antiviral activity against West Nile virus (WNV) replicon. Therefore, this study aimed to investigate the relationship between enzymatic and antiviral activities of ChOAS-L...

Interferon-tau (IFN-τ) is a type I interferon and considered as a pregnancy recognition signal in ruminants. Our previous reports have confirmed that IFN-τ has a potential anti-inflammatory effect in macrophage. However, the anti-inflammatory effect of IFN-τ on endometritis has never been reported. Thus, the aim of this study was to investigate the effects of IFN-τ in a mouse model of Staphylococcus aureus-induced endometritis. The histopathological and myeloperoxidase activity results showed that IFN-τ could protect the uterus from S...

Class I-restricted T cell-associated molecule (CRTAM) is an activation marker expressed on the cell surface of activated invariant natural killer T (iNKT) cells, CD8(+) T cells, and a small subset of CD4(+) T cells. CRTAM has also been associated with a proinflammatory profile in murine CD4(+) T cells. However, CRTAM has not been thoroughly explored in human cells. This work focused on evaluating CRTAM expression in human iNKT lymphocytes after activation with α-galactosylceramide, its widely used specific glycolipid antigen...

Because of its tumor-suppressive effect, interferon-based therapy has been used for the treatment of melanoma. However, limited data are available regarding the antitumor effects of pegylated interferons, either alone or in combination with approved anticancer drugs. We report that treatment of human WM-266-4 melanoma cells with peginterferon beta-1a induced apoptotic markers. Additionally, peginterferon beta-1a significantly inhibited the growth of human SK-MEL-1, A-375, and WM-266-4 melanoma xenografts established in immunocompromised mice...

To provide fundamental insights into the mechanism of Hepatitis C virus (HCV), we conduct the present study to improve further understanding of the interaction between HCV and cytokines. Two hundred one patients were enrolled in this study. Seventy-eight patients matching the study group in terms of age and gender with negative serology for hepatitis viruses, HIV virus, and with liver enzyme levels within normal range were selected as the control group. Patients were diagnosed with positive hepatitis C by detection of positive HCV antibodies in serum...

The phase 2b EMERGE study compared the efficacy/safety of peginterferon lambda-1a (Lambda) and peginterferon alfa-2a (Alfa), both with ribavirin (RBV), for treatment of chronic hepatitis C virus (HCV) infection. A key safety finding was a higher frequency of hyperbilirubinemia with Lambda/RBV versus Alfa/RBV. To characterize mechanisms of hyperbilirubinemia associated with Lambda/RBV, we conducted a retrospective analysis of safety data from the HCV genotype 1 and genotype 4 cohort of the EMERGE study. Subjects were randomized to once-weekly Lambda (120/180/240 μg) or Alfa (180 μg), with daily RBV, for 48 weeks...

Interleukin-27 (IL-27) inhibits the replication of many viruses, but the mechanism differs according to virus and cell type. In this study, we observed that IL-27 expression was upregulated in herpes simplex virus type 1 (HSV-1)-infected SJL/J mice, which led us to further investigate the role of IL-27 in HSV-1 infection using epithelial, glioma, and immunological cells as cell models. We showed that in all studied cell lines, the IL-27 messenger RNA (mRNA) level was upregulated due to the HSV-1 infection. When the cells were primed with IL-27 before the virus infection, the virus release was prevented, indicating an antiviral role of IL-27 in HSV-1 infection...

Anemia is a complication of interferon-containing hepatitis C treatments. We characterized effects of interferon-based therapy on hepcidin and erythropoietin (EPO) production, iron metabolism, hemolysis, and hematopoiesis. Standard hemopoiesis [reticulocyte hemoglobin (Hb), reticulocyte production index (RPI), free Hb, and haptoglobin], iron biochemistry, hepcidin, and EPO levels were measured in 10 subjects over 12 weeks. There was a rapid decline in Hb during treatment, from a mean pretreatment (t = 0 weeks) Hb of 158...

Previous epidemiologic studies showed an increased risk of neutralizing antibody (NAb) development against Interferon beta in multiple sclerosis patients who smoke. Cotinine is an easily detectable metabolite of nicotine and, therefore, can be used as an objective surrogate marker for smoking status. We measured cotinine levels in NAb-positive and NAb-negative patients to find a potential association of nicotine consumption and NAb development. Cotinine was measured in 37 patients with known smoking status and in 123 patients with unknown smoking status, all of whom were routinely tested for NAb...

Previously, we demonstrated that Lactobacillus salivarius was more abundant in patients with rheumatoid arthritis (RA), an inflammatory autoimmune disease wherein the gut microbiota is altered, than in healthy individuals. However, the effect of L. salivarius in RA is unclear. Hence, we investigated the effect of L. salivarius isolated from patients with RA on collagen-induced arthritis (CIA) in mice. L. salivarius UCC118 or L. plantarum WCFS1 isolated from patients with RA was administered orally for 5 weeks, starting from 2 weeks before the induction of arthritis in DBA/1 mice...

Hepatitis C virus (HCV) is the leading cause of liver fibrosis and hepatocellular carcinoma (HCC). At present, there is no predictive biomarker for the patients at high risk of developing HCC. In this study, we examined the association between single-nucleotide polymorphisms (SNPs) in 3 innate immunity genes [2'-5'oligoadenylate synthetase 1 (OAS1) rs10774671, interleukin 28B (IL28B) rs12979860, and low molecular mass polypeptide 7 (LMP-7) at codon 49] besides cytomegalovirus (CMV) coinfection and susceptibility to HCC in genotype 4 (GT4) chronically infected Egyptian patients...

Treatment of hepatitis C virus (HCV) in end-stage renal disease (ESRD) patients is an important issue before kidney transplantation (KT). The aim of the study is to assess the efficacy and tolerability of HCV treatment with pegylated interferon (PEG IFN)-α 2b in children with ESRD. The study included 17 children, aged 3-18 years with ESRD on hemodialysis (HD), with chronic HCV. They received 40 μg/m(2) of PEG IFN-α 2b once-weekly subcutaneous injections for 48 weeks. Early virological response (EVR) was achieved in 76...

The interferon lambda (IFN-λ) cytokines have well-known antiviral properties, yet their contribution to immune regulation is not well understood. Epithelial cells represent the major target cell of IFN-λ; peripheral blood mononuclear cells are generally considered nonresponsive, with the exception of plasmacytoid dendritic cells (pDCs). In this study we aimed to define the potential for discrete subpopulations of cells to directly respond to IFN-λ. Analysis of peripheral blood leukocytes reveals that, while pDCs uniformly express the highest levels of IFN-λ receptor, a small proportion of B cells and monocytes also express the receptor...

Sendai virus (SeV), a murine paramyxovirus, has been used to study the induction of type I interferon (IFN) subtypes in robust quantities. Few studies have measured whether the IFN that SeV induces actually fulfills its intended purpose of interfering with virus-mediated effects in the cells in which it is produced. We determined the effects of IFN on SeV-mediated cytopathic effects (CPE) and the ability of IFN to protect against virus infection. SeV-induced biologically active IFN resulted in Jak/STAT activation and the production of a number of interferon-stimulated genes (ISGs)...

The research was performed to explore the diagnosis value of dynamic serum calprotectin (SC) expression for sepsis in postoperative intensive care unit patients. One hundred sixty-three patients who met the inclusion criteria served as the study group. All cases in the study group were further divided into the sepsis subgroup (51 cases) and the nonsepsis subgroup (112 cases). Fifty healthy volunteers served as the control group. The levels of SC and other laboratory indexes including complete blood counts, leukocytes, the immature-to-total-neutrophil ratio, procalcitonin (PCT), C-reactive protein, and blood lactate were detected, cytokines [interleukin (IL)-2, IL-6, and interferon-γ] released by neutrophils were also determined...

Studies suggest interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) may be beneficial in obesity-related disorders with inconsistent results. This study was designed to investigate and compare their pathophysiological roles in lipid metabolism with gene knockout approach. Male wild-type (WT), IL-6 knockout (IL-6(-/-)), and TNF-α knockout (TNF-α(-/-)) mice were maintained on either a chow diet or a high-fat diet (HFD) for 12 weeks. Indices of lipid metabolism in blood, adipose, and liver were determined...

Most resuscitated victims of out-of-hospital cardiac arrest who survive to hospital expire due to the postresuscitation syndrome. This syndrome is characterized by a sepsis-like proinflammatory state. The objective of this investigation was to determine whether a relationship exists between the rise of tumor necrosis factor (TNF), a proinflammatory cytokine, following return of spontaneous circulation (ROSC), and early postarrest survival in a clinically relevant animal model of spontaneous ventricular fibrillation (VF)...
