PURPOSE: To compare the levels of cytokines and growth factor in aqueous humor of the patients with chronic primary angle closure glaucoma (PACG) and cataract. METHODS: Aqueous humor samples were collected from 19 chronic PACG patients and compared with 14 nonglaucomatous controls presenting for cataract surgery. The levels of 27 cytokines and growth factors were measured in the aqueous samples using multiplex bead immunoassay and compared across groups. RESULTS: Significantly higher levels of interleukin (IL)-8 (p < 0...

BACKGROUND AND PURPOSE: Celastrol, a quinone methide triterpene isolated from the root extracts of Tripterygium wilfordii, can greatly induce the gene expression activity of heme oxygenase-1 (HO-1) to achieve disease prevention and control. HO-1 induction was recently shown to result in anti-HCV activity by inducing type I interferon and inhibiting hepatitis C virus (HCV) NS3/4A protease activity. The aim of the present study is to evaluate the anti-HCV activity of celastrol and characterize its mechanism of inhibition...

BACKGROUND: Although Nucleos(t)ide analogue therapy is thought to suppress chronic hepatitis B(CHB) via regulation of inflammatory cytokines/chemokines, the mechanism is still unclear. In this study, serum cytokine/chemokine levels were measured in CHB patients treated with entecavir, and the association with antiviral response was analyzed. METHODS: Seventy-eight Japanese patients with CHB were enrolled, and serum cytokine/chemokine levels were measured at baseline and at 12, 24, and 48 weeks of entecavir treatment using the MULTIPLEX kit...

RATIONALE: Microvesicles (MV) act as a non-soluble means of inter-cellular communication, with effector roles in disease pathogenesis and potentially as biomarkers. Previously, we reported that neutrophil MV expressing alpha-2-macroglobulin (A2MG) are protective in experimental sepsis and associate with survival in a small cohort of patients with sepsis due to community acquired pneumonia (CAP). OBJECTIVES: To characterise MV profiles in sepsis due to CAP or faecal peritonitis (FP) and determine their relation to outcome...

Drug-induced diabetes is one of the factors contributing to the increasing incidence of diabetes worldwide. This review considers the frequency, pathogenesis and treatment of drug-induced diabetes. Drugs that induce diabetes include hormonal therapy, especially glucocorticoids and androgen blockers, cardiovascular drugs, especially statins, beta-blockers and diuretics, antipsychotics, especially clozapine, olanzapine and quetiapine, antiretrovirals (protease inhibitors and non-reverse transcriptase inhibitors - NRTIs) and other drugs (mechanistic target of rapamycin inhibitors -mTORs, post organ transplantation drugs, tyrosine kinase inhibitors and interferon-alpha)...

We have reported a murine model of autoimmune cholangitis, generated by altering the AU rich element by deletion of the IFN-γ 3'UTR region (coined ARE-Del(-/-) ), that has striking similarities to human primary biliary cholangitis (PBC) with female predominance. Previously, we suggested that the gender bias of autoimmune cholangitis was secondary to intense and sustained type I and II IFN signaling. Based on this thesis, and to define the mechanisms that lead to portal inflammation, we specifically addressed the hypothesis that type I IFNs are the driver of this disease...

Signal Transducer and Activator of Transcription 1 (STAT1) has been demonstrated to function as a critical mediator in multiple cell processes, such as cell proliferation, cell death, and innate immune response. Interestingly, two orthologues of human STAT1, including STAT1a and STAT1b genes have been identified in different fish. However, the detailed roles of fish STAT1a in virus replication still remained largely uncertain. Here, we cloned a STAT1a from orange-spotted grouper Epinephelus coioides (EcSTAT1a) and characterized its roles during fish virus infection...

MicroRNA-22 (miR-22) is a highly conserved microRNA that can regulate cell proliferation, oncogenesis, and cell maturation, especially during stress. In hematopoietic stem cells (HSCs) miR-22 has been reported to be involved in the regulation of key self-renewal factors including Tet2. Recent work demonstrates that miR-22 also participates in regulation of the interferon response, and expression profiling studies suggest that it is variably expressed at different stages in erythroid differentiation. We thus hypothesized that miR-22 regulates maturation of erythroid progenitors during stress hematopoiesis through its interaction with interferon...

Inflammation has been shown to play an important role in the mechanisms involved in the pathogenesis of hypertension. Connexins (Cxs)-based gap junction channels (GJCs) or hemichannels (HCs) are involved in the maintenance of homeostasis in the immune system. However, the role of Cx43-based channels in T-lymphocytes in mediating the immune response in essential hypertension is not fully understand. The present study was designed to investigate the role of Cxs-based channels in T lymphocytes in the regulation of hypertension-mediated inflammation...

BACKGROUND: Corticosteroid sparing is required in 15% to 40% of adults with persistent or chronic primary immune thrombocytopenic purpura (ITP). Herein, the efficacy of immunomodulatory drugs (dapsone, interferon alpha, danazol, and hydroxychloroquine as second-third-line therapies in ITP is investigated. METHODS: MEDLINE was searched for studies that included patients with persistent or chronic primary ITP and published before the end of December 2014. Two investigators independently extracted data regarding study design, patient characteristics, dosage schedule, time to response, and occurrence of adverse events...

Giant cell tumor (GCT) of bone is a locally aggressive benign neoplasm that is associated with a large biological spectrum ranging from latent benign to highly recurrent and occasionally metastatic malignant bone tumor. It accounts for 4-10% of all bone tumors and typically affects the meta-epiphyseal region of long bones of young adults. The most common site involved is the distal femur, followed by the distal radius, sacrum, and proximal humerus. Clinical symptoms are nonspecific and may include local pain, swelling, and limited range of motion of the adjacent joint...

PURPOSE: Drug-induced oral lichenoid reactions (DIOLRs) have been extensively reported in the literature, but the validity of the causality relationship between any drug and the oral lichenoid lesions (OLLs) still remains questionable. We sought to determine whether this causality relationship really exists, whether a resolution of the oral lesions upon withdrawal occurs, and what the most common alleged offending medications are. METHODS: Nine electronic databases from January 1966 to December 2016 were systematically searched to identify all relevant studies selected with specific inclusion criteria (a clinical and histopathological diagnosis of DIOLRs, and clearly statement on the systemic offending medication)...

Autosomal dominant polycystic kidney disease (ADPKD) is caused by mutations in PKD1 or PKD2 which encodes polycystin-1 (PC1) and polycystin-2, respectively. PC1 was previously shown to slow cell proliferation and inhibit apoptosis but the underlying mechanisms remain elusive or controversial. Here we showed in cultured mammalian cells and Pkd1 knockout mouse kidney epithelial cells that PC1 and its truncation mutant comprising the last five transmembrane segments and the intracellular C-terminus (PC1-5TMC) down-regulate the phosphorylation of protein kinase R (PKR) and its substrate eukaryotic translation initiation factor 2 alpha (eIF2α)...

BACKGROUND: New evidence has shown that reduced β2-glycoprotein I (β2GPI) has anti-oxidative stress and anti-inflammatory activity. However, the details are still poorly understood. This study aims to prepare stable reduced β2GPI with its native bioactivity in vitro. METHODS: Human β2GPI was purified from plasma first with perchloric acid precipitation and then purified with a series of chromatography methods including Sephadex G-25 desalting, SP HP, AF-heparin HC-650 M, and Sephacryl S-200...

There are an estimated 400 million chronic carriers of HBV worldwide; between 15 and 20 million have serological evidence of exposure to HDV. Traditionally, regions with high rates of endemicity are central and northern Africa, the Amazon Basin, eastern Europe and the Mediterranean, the Middle East and parts of Asia. There are two types of HDV/HBV infection which are differentiated by the previous status infection by HBV for the individual. Individuals with acute HBV infection contaminated by HDV is an HDV/HBV co-infection, while individuals with chronic HBV infection contaminated by HDV represent an HDV/HBV super-infection...
