Although lines of evidence demonstrated that cytokines play an important role in the pathogenesis of major depressive disorder (MDD), none of the them have been established as reliable biomarkers. We use our previous whole-genome cRNA microarray data to identify epithelial cell-derived neutrophil-activating peptide 78 (ENA78), the most differentially expressed cytokine in peripheral blood between MDD patients and healthy controls; and then we confirmed the result by the quantitative reverse transcription-polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA) for mRNA and protein level, respectively, in an independent drug-naïve first-episode sample set...

Mortality associated with breast cancer is attributable to aggressive metastasis, to which TNFα plays a central orchestrating role. TNFα acts on breast tumor TNF receptors evoking the release of chemotactic proteins (e.g. MCP-1/CCL2). These proteins direct inward infiltration/migration of tumor-associated macrophages (TAMs), tumor-associated neutrophils (TANs), myeloid-derived suppressor cells (MDSCs), T-regulatory cells (Tregs), T helper IL-17-producing cells (Th17s), metastasis-associated macrophages (MAMs) and cancer-associated fibroblasts (CAFs)...

BACKGROUND: Resistance to intravenous immunoglobulin (IVIG) therapy is a risk factor for coronary lesions in patients with Kawasaki disease (KD). Risk-adjusted initial therapy may improve coronary outcome in KD, but identification of high risk patients remains a challenge. This study aimed to develop a new risk assessment tool for IVIG-resistance using advanced statistical techniques. METHODS: Data were retrospectively collected from KD patients receiving IVIG therapy, including demographic characteristics, signs and symptoms of KD, and laboratory results...

Single-walled carbon nanotubes (SWCNTs) are experimentally utilized in in vivo imaging and photothermal cancer therapy owing to their unique physicochemical and electronic properties. For these applications, pristine carbon nanotubes are often modified by polymer surfactant coatings to improve their biocompatibility, adding more complexity to their recognition and biodegradation by immuno-competent cells. Here, we investigate the oxidative degradation of SWCNTs catalyzed by neutrophil myeloperoxidase (MPO) using bandgap near-infrared (NIR) photoluminescence and Raman spectroscopy...

BACKGROUND: We recently identified a regulatory rheumatoid factor (regRF), the production of which is associated with autoimmune disease resistance and remission. In studies of regRF in the blood of healthy rats, spontaneous increases in the regRF level were noted. We suggest that in the normal state, a mechanism exists for maintaining the activity of the pool of regRF-producing lymphocytes at a level that makes it possible to control the expansion of autoreactive lymphocytes. OBJECTIVE: The purpose of this study was to test the hypothesis that the endogenous stimulator of regRF production is Fc fragments of IgG that are formed upon exposure to the proteases of neutrophils...

BACKGROUND: The role of immunoglobulin (Ig)-E in occupational asthma (OA) due to low molecular weight (LMW) agents is not well established compared to classical atopic asthma. In the present study we evaluate whether anti-IgE monoclonal antibody (mAb) has an effect in a mouse model of OA, using persulfate salts. METHODS: On days 1 and 8, BALB/C mice were dermally sensitized with 5% ammonium persulfate (AP) or dimethyl sulfoxide (DMSO). On days 15, 18 and 21 animals were injected intraperitoneally with anti-IgE mAb or PBS 6 hours before challenge with AP or saline...

BACKGROUND: Autologous hematopoietic stem cell transplantation (aHSCT) is the recommended standard upfront treatment for transplant eligible myeloma patients. Considering possible complications related to chemotherapy-cytokine mobilization, cytokine-alone mobilization is often used. We compared mobilization with filgrastim alone to pegfilgrastim alone in newly diagnosed myeloma patients after induction treatment with bortezomib and dexamethasone. The comparison was made between peripheral blood stem cell (PBSC) yields, number of apheresis, hematopoietic stem cell subsets, and time to neutrophil and platelet engraftment after aHSCT...

BACKGROUND: Gastroenterostomy and stent placement are the most common palliative procedures for patients with a gastric outlet obstruction caused by advanced pancreatic adenocarcinoma. Gastroenterostomy is regarded as the optimum treatment for patients in whom a longer survival is expected, while stent placement is preferred for patients whose survival is likely to be relatively short. However, prognosis of such patients has not been fully evaluated. METHODS: This study included patients undergoing gastroenterostomy or duodenal stent placement for gastric outlet obstruction caused by advanced pancreatic adenocarcinoma between 2002 and 2015...

Environmental and hormonal factors are implicated in dysimmunity in multiple sclerosis. We investigated whether bisphenol-A, a prominent contaminant with endocrine-disrupting capabilities, altered susceptibility in an inflammatory model of multiple sclerosis. We found that gestational, but not adult, exposure to bisphenol-A increased the development of experimental autoimmune encephalomyelitis in adulthood in male, but not female, mice when a suboptimal disease-inducing immunization was used. Gestational bisphenol-A in male mice primed macrophages in adulthood and raised granulocyte-colony stimulating factor and neutrophil counts/activity postsuboptimal immunization...

Peptoanaerobacter stomatis is a newly appreciated taxon associated with periodontal diseases; however, little is known about the organism's pathogenic potential or its interaction with the host immune response. Neutrophils are the most abundant innate immune cell present in the gingival tissue and function to constrain the oral microbial challenge. However, some periodontal pathogens have developed strategies to evade phagocytosis and killing by neutrophils. Therefore, to begin to understand the role of P. stomatis in periodontitis, we studied its interactions with human neutrophils...

Staphylococcus aureus is a major cause of skin and soft-tissue infection. The bacterium expresses four major proteases emerging as virulence factors; aureolysin (Aur), V8 protease (SspA), staphopain A (ScpA), and staphopain B (SspB). We hypothesized that human galectin-3, a β-galactoside-binding lectin involved in immune regulation and antimicrobial defense, is a target for these proteases, and that proteolysis of galectin-3 is a novel immune evasion mechanism. Indeed, supernatants from laboratory strains and clinical isolates of S...

In vivo and ex vivo imaging were used to investigate the function of galectin-3 (Gal-3) during the process of leukocyte recruitment to the inflamed microcirculation. The cremasteric microcirculation of wild-type (C57BL/6), Gal-3(-/-), and CX3CR1(gfp/+) mice were assessed by intravital microscopy after PBS, IL-1β, TNF-α, or recombinant Gal-3 treatment. These cellular responses were investigated further using flow-chamber assays, confocal microscopy, flow cytometry, PCR analysis, and proteome array. We show that mechanisms mediating leukocyte slow rolling and emigration are impaired in Gal-3(-/-) mice, which could be because of impaired expression of cell adhesion molecules and an altered cell surface glycoproteome...

BACKGROUND: Adult-onset asthma is an important but relatively understudied asthma phenotype and little is known about its natural course and prognosis. The remission rate is believed to be low, and it is still obscure which factors predict remission or persistence of the disease. OBJECTIVE: To determine the remission rate, and identify predictors of persistence and remission of adult-onset asthma. METHODS: Two hundred adult patients with recently diagnosed (<1 year) asthma were recruited from secondary and tertiary pulmonary clinics and prospectively followed for 5 years...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is currently the third leading cause of death and there is a huge unmet clinical need to identify disease biomarkers in peripheral blood. Compared to gene level differential expression approaches to identify gene signatures, network analyses provide a biologically intuitive approach which leverages the co-expression patterns in the transcriptome to identify modules of co-expressed genes. METHODS: A weighted gene co-expression network analysis (WGCNA) was applied to peripheral blood transcriptome from 238 COPD subjects to discover co-expressed gene modules...

BACKGROUND AND PURPOSE: Exposure to nanoparticulate pollution has been implicated in platelet-driven thrombotic events such as myocardial infarction. Inflammation and impairment of nitric oxide (NO) bioavailability have been proposed as potential causative mechanisms. It is unclear, however, whether airways exposure to combustion-derived nanoparticles such as diesel exhaust particles (DEP) or carbon black (CB) can augment platelet aggregation in vivo and the underlying mechanisms remain undefined...

BACKGROUND AND PURPOSE: Neuroinflammation is initiated by a variety of stimuli including infections, sepsis, neurodegenerative diseases or traumatic brain injury and if not adequately controlled can lead to various degrees of neuronal damage and behavioural impairment. A critical event in the initial steps of inflammation is neutrophil extravasation. Semicarbazide sensitive amine oxidase (SSAO, also known as vascular adhesion protein 1 or VAP-1) regulates neutrophil adhesion and extravasation...

BACKGROUND Neutrophil-lymphocyte ratio (NLR) is an indicator of the inflammatory state, and its increase has been shown to be a negative prognostic factor for many malignancies. The aim of this study was to determine whether there was a relationship between NLR and tumor aggressiveness in gastric cancer patients and to investigate the prognostic significance of NLR. MATERIAL AND METHODS The medical records of 189 patients with gastric cancer between January 2009 and January 2014 were examined for the presence of metastasis, tumor staging, tumor differentiation grade, and preoperative NLR value...
