The tumor-selective viral replication capacity and pro-apoptotic effects of oncolytic reovirus have been reported to be dependent on the presence of an activated RAS pathway in several solid tumor types. However, the mechanisms of selective anticancer efficacy of the reovirus-based formulation for cancer therapy (Reolysin, pelareorep) have not been rigorously studied in soft tissue sarcomas (STS). Here we report that Reolysin triggered a striking induction of the anti-angiogenic chemokine interferon-γ-inducible protein 10 (IP-10)/CXCL10 (CXC chemokine ligand 10) in both wild type and RAS mutant STS cells...

CpG oligodeoxynucleotides (ODNs) are proved to have strong immune stimulatory activity. Plasmids containing CpG ODNs could be conveniently and low-costly used as vaccine adjuvant. However, they are different among various plasmids, motif repeats, species, etc. In the present study, plasmid pcDNA3.1 (+) containing five repetitions of CpG ODN 1670A named pcDNA3.1-1670A*5 with strong immunostimulation was screened out from twelve recombinant plasmids and three empty vectors by cell proliferation activity, interferon promoter activities and immune related gene expressions in CIK cells...

Exposure to high fluorine can cause toxicity in human and animals. Currently, there are no systematic studies on effects of high fluorine on blood cellular immunity and humoral immunity in mice. We evaluated the alterations of blood cellular immunity and humoral immunity in mice by using flow cytometry and ELISA. In the cellular immunity, we found that sodium fluoride (NaF) in excess of 12 mg/Kg resulted in a significant decrease in the percentages of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+) T lymphocytes in the peripheral blood...

Interferon regulator factor 4 (IRF4) is characterized to be a member of interferon regulatory family, which is predominantly expressed in bone marrow plasma cells of patients with multiple myeloma (MM). Recent studies indicated IRF4 is critical for T-help cells (Th17) differentiation and interleukin-17 (IL-17) secretion. Here, a total of 58 MM patients were enrolled in this study, the proportions of Th17 cells and T regulatory (Treg) cells in peripheral blood mononuclear cells (PBMCs) were determined by flow cytometric analysis...

The last two decades have witnessed enormous growth in the field of cancer immunity. Mechanistic insights of cancer immunoediting have not only enhanced our understanding but also paved the way to target and/or harness the innate immune system to combat cancer, called cancer immunotherapy. Cyclic GMP-AMP synthase (cGAS)/Stimulator of interferon genes(STING) pathway has recently emerged as nodal player in cancer immunity and is currently being explored as potential therapeutic target. Although therapeutic activation of this pathway has shown promising anti-tumor effects in vivo, evidence also indicates the role of this pathway in inflammation mediated carcinogenesis...

Herpes simplex virus type 1 (HSV-1) had led to kinds of clinical disorders and became an important cause of morbidity and mortality worldwide, such as herpetic gingivostomatitis in children. Previous studies reported that HSV-1 infection is common and has evolved a variety of mechanisms to evade the immune system, such as dysregulation of miRNAs. However, reports concerning the role of miRNA in HSV-1infection are limited. Here, we report that a host microRNA, miR-373, was significantly upregulated by HSV-1 infection in Hela cells and patients with herpetic gingivostomatitis and it facilitated HSV-1 replication in vitro...

Atopic dermatitis (AD) is a chronic inflammatory skin disease caused by environmental and chemical allergens. Despite the complexity of its pathogenesis, many investigations have shown that substances having anti-inflammatory activities alleviated the pathology of AD. Here, we evaluated the effects of mineral-balanced deep sea water (DSW) on AD-like skin damage in both in vitro and in vivo. The results showed that mineral-balanced DSW regressed inflammatory chemokines, such as macrophage-derived chemokine (MDC), thymus- and activation-regulated chemokine (TARC) and regulated on activation, normal T-cell expressed and secreted (RANTES), and cytokines, interleukin (IL)-6 and granulocyte-macrophage colony-stimulating factor (GM-CSF) mRNA expression in HaCaT immortal human keratinocyte treated with tumor necrosis factor (TNF)-α/ interferon (IFN)-γ mixture...

The Mab-21 gene family is crucial for animal development. A deficiency in the Mab-21 genes associates with several defects, including skeletal malformation in mice and humans. In this study, we observed that mice lacking Mab21l1 displayed an unclosed fontanelle, suggesting impaired calvarial bone development. Cells isolated from the calvaria of these mice showed a greater osteoblast differentiation potential as evidenced by the abundance of mineralized bone nodules and higher expression levels of osteogenic markers than wild-type cells...

Chronic hepatitis B (CHB) has become a treatable and controllable disease. The current nucleos(t)ide analogue (NUC) and pegylated interferon therapies effectively help slow disease progression and reduce the risk of cirrhosis, hepatocellular carcinoma (HCC), and CHB-associated mortality. Long-term viral suppression is easily achievable by NUC therapy, with limited adverse reactions. However, several unmet requirements still exist, including safety and risk-stratified HCC surveillance among patients who received long-term NUC therapy...

Chronic hepatitis B virus (HBV) infection is a global public health issue. There are >250 million people chronically infected with HBV, and these chronic carriers are at high risk of developing end-stage liver diseases and hepatocellular carcinoma. Patients with chronic hepatitis B (CHB) usually acquire the virus perinatally, while most patients infected during adulthood develop acute hepatitis B (AHB), which usually results in viral clearance. HBV infection is noncytopathic, and liver injury is mostly contributed by host immune responses...

Chronic hepatitis B virus (HBV) infection remains a major global health burden. Currently, the approved therapeutic regimens include nucleos(t)ide analogues (NAs) and either interferon or pegylated interferon. NA therapy is generally safe and well tolerated, but the rate of posttreatment virologic relapse is high, making NA treatment a lifetime commitment. The benefits of pegylated interferon treatment include a finite duration, more-durable response and absence of viral resistance. However, sustained response to interferon alone is achieved only in a minority of patients, and side effects are common, which limit its clinical use...

Pregnant women and animals have increased susceptibility to a variety of intracellular pathogens including Listeria monocytogenes (LM), which has been associated with significantly increased level of sex hormones such as progesterone. CD8 T memory(Tm) cell-mediated antigen-non-specific IFN-γ responses are critically required in the host defense against LM. However, whether and how increased progesterone during pregnancy modulates CD8 Tm cell-mediated antigen-non-specific IFN-γ production and immune protection against LM remain poorly understood...

Conventional control and eradication strategies for bovine tuberculosis (BTB) face tremendous difficulties in developing countries; countries with wildlife reservoirs, a complex wildlife-livestock-human interface or a lack of veterinary and veterinary public health surveillance. Vaccination of cattle and other species might in some cases provide the only suitable control strategy for BTB, while in others it may supplement existing test-and-slaughter schemes. However, the use of live BCG has several limitations and the global rise of HIV/AIDS infections has furthermore warranted the exploration of inactivated vaccine preparations...

OBJECTIVES: Multiple sclerosis (MS) is a demyelinating disorder with a complex autoimmune pathophysiology. Its initiation and progression correlate with IL-17 and the related transcription factor, RORγt. All-trans retinoic acid (ATRA) is a bioactive derivative of vitamin A, and docosahexaenoic acid (DHA) is an active metabolite of omega-3 fatty acid; both have immunomodulatory effects in many immune disorders. This study investigated the effects of DHA and ATRA individually and in combination on IL-17 and RORγt gene expression in peripheral blood mononuclear cells (PBMCs) of relapsing-remitting MS (RRMS) patients who were receiving interferon beta (IFN-β)...

NF-κB pathway and p38MAPK (p38mitogen-activated protein kinase) pathway have been shown to play a key role in neuroinflammation, however, the phosphorylation modification is an important process that affects the activation of above pathways. Dual-specificity tyrosine-phosphorylation-regulated kinase 2(Dyrk2), as a phosphokinase that can phosphorylate signal molecules, has been demonstrated to regulate Type I Interferon(TIF) by promoting ser527 phosphorylation of TBK1. Therefore, to investigate the role of Dyrk2 in neuroinflammation, we analyzed the effect of Dyrk2 on LPS-induced the activation of microglia...

Latent tuberculosis (TB) is the main hurdle in reaching the goal of "Stop TB 2050". Tuberculin skin and Interferon-gamma release assay tests used currently for the diagnosis of TB infection cannot distinguish between active disease and latent tuberculosis infection (LTBI) and hence new and sensitive protein markers need to be identified for the diagnosis. A protein Rv3716c from Mycobacterium tuberculosis (MtbRv3716c) has been identified as a potential surrogate marker for the diagnosis of LTBI. Here, we present characterization of MtbRv3716c (∼13 kDa) using both biophysical and X-Ray crystallographic methods...

Chronic overnutrition and obesity induces low-grade inflammation throughout the body. Termed "meta-inflammation," this chronic state of inflammation is mediated by macrophages located within the colon, liver, muscle, and adipose tissue. A sentinel orchestrator of immune activity and homeostasis, macrophages adopt variable states of activation as a function of time and environmental cues. Meta-inflammation phenotypically skews these polarization states and has been linked to numerous metabolic disorders. The past decade has revealed several key regulators of macrophage polarization, including the signal transducer and activator of transcription family, the peroxisome proliferator-activated receptor gamma, the CCAAT-enhancer-binding proteins (C/EBP) family, and the interferon regulatory factors...
