The translocator protein (TSPO) ligands impacted inflammatory and immune responses. However, the exact effects of TSPO ligands on Th1 responses in vitro and in vivo are still unclear. In the current study, we found that TSPO ligands, FGIN1-27 and Ro5-4864, suppressed the cytokine production in a dose- dependent manner by purified human CD4(+) T cells from PBMCs after stimulation. TSPO ligands inhibited the production of IFN-γ by memory CD4(+) T cells and the differentiation of naïve CD4(+) T cells into Th1 cells via  suppressing the activity of the corresponding transcription factors as indicated by reduced expression of T-bet and downregulation of STAT1, STAT4 and STAT5 phosphorylation...

Transient receptor potential channel 5 (TrpC5) is member of the TrpC subgroup, and it forms a receptor-activated non-selective Ca(2+) channel. The architecture of the TrpC5 channel is poorly understood. Here, we report that TrpC5 is a key factor in regulating differentiation in colorectal cancer. Through a study of specimens from a large cohort of patients with colorectal cancer, we found that TrpC5 was highly expressed and its cellular level correlated with tumor grade. We further showed that up-regulated TrpC5 caused a robust [Ca(2+)]i rise, increased Wnt5a expression, and the nuclear translocation of β-catenin, leading to a reduction of cancer differentiation and an increase of cancer cell stemness...

Streptococcus pneumoniae and influenza are the world's foremost bacterial and viral respiratory pathogens. We have previously described a gamma-irradiated influenza (γ-FLU) vaccine that provides cross-protective immunity against heterosubtypic infections. More recently, we reported a novel non-adjuvanted gamma-irradiated S. pneumoniae (γ-PN) vaccine that elicits serotype-independent protection. Considering the clinical synergism of both pathogens, combination of a serotype-independent pneumococcal vaccine with a broad-spectrum influenza vaccine to protect against both infections would have considerable clinical impact...

Hepatopulmonary syndrome (HPS) is a lung complication in various liver diseases, with high incidence, poor prognosis and no effective non-surgical treatments in patients with hepatocirrhosis. Therefore, assessing HPS pathogenesis to explore proper therapy strategies is clinically relevant. In this study, male Sprague-Dawley rats underwent sham operation or common bile duct ligation (CBDL). Two weeks post-surgery, the following groups were setup for 2 weeks of treatment: Sham + normal saline, CBDL + CXCR2 antagonist SB225002, CBDL + TNF-α antagonist PTX, and CBDL + normal saline groups...

AIMS: Type 2 diabetes (T2D) is characterized by insulin resistance, mitochondrial dysregulation, and, in some studies, exercise resistance in skeletal muscle. Regulation of autophagy and mitochondrial dynamics during exercise and recovery is important for skeletal muscle homeostasis, and these responses may be altered in T2D. MATERIALS AND METHODS: We examined the effect of acute exercise on markers of autophagy and mitochondrial fusion and fission in skeletal muscle biopsies from patients with T2D (n=13) and weight-matched controls (n=14) before, immediately after and 3h after an acute bout of exercise...

Fatty liver diseases are complications of the metabolic syndrome associated with obesity, insulin resistance and low grade inflammation. Our aim was to uncover mechanisms contributing to hepatic complications in this setting. We used foz/foz mice prone to obesity, insulin resistance and progressive fibrosing NASH. Foz/foz mice are hyperphagic but WT-matched calorie intake failed to protect against obesity, adipose inflammation and glucose intolerance. Obese foz/foz mice had similar physical activity level but reduced energy expenditure...

In liver cirrhosis, the altered levels of vasoactive substances, especially endothelin-1 (ET-1) and nitric oxide (NO) leads to elevated intrahepatic resistance, increased portal-systemic collaterals, and abnormal intra- and extra-hepatic vascular responsiveness. These derangements aggravate portal hypertension-related complications such as gastroesophageal variceal bleeding. Homocysteine, a substance implicated in cardiovascular diseases, has been found with influences on vasoresponsiveness and angiogenesis...

Studies suggest that metformin, widely used for treating type 2 diabetes, possesses innate antineoplastic properties. For metabolic syndrome patients with hepatocellular carcinoma, metformin may provide antitumoral effects  We evaluated the impact of metformin on tumor growth and visceral fat composition using relevant preclinical models of metabolic syndrome.  EXPERIMENTAL DESIGN: Studies were performed in three hepatoma cell lines, in HepG2 xenograft mice fed with standard chow-diet (SC), 60% high-fat diet (HFD) or 30% fructose diet (FR), and an ex vivo model of human cultured hepatocellular carcinoma slices...

Immune deposits are often observed along the tubular basement membrane in patients with lupus nephritis, but the role of anti-dsDNA antibody deposition on tubulo-interstitial inflammation remains to be investigated. We examined the effect of human polyclonal anti-dsDNA antibodies on inflammatory processes in cultured proximal renal tubular epithelial cells (HK-2 cells) and their association with serum levels of IL-6, IL-8 and MCP-1 in patients. Binding of anti-dsDNA antibodies to HK-2 cells was investigated by cellular ELISA, flow cytometry and immunohistochemistry...

The planar cell polarity (PCP) pathway is critical for proper embryonic development of the neural tube and heart. Mutations in these genes have previously been implicated in the pathogenesis of neural tube defects (NTDs), but not in congenital heart defects (CHDs) in humans. We systematically identified the mutation patterns of CELSR1-3 , one family of the core PCP genes, in human cohorts composed of 352 NTD cases, 412 CHD cases, and matched controls. A total of 72 disease-specific rare novel coding mutations were identified, of which 37 were identified in CHD cases, and 36 were identified in NTD patients...

Microsomal prostaglandin E2 synthase-1 (mPGES-1) constitutes an essential player of inflammation and is involved in the pathogenesis of rheumatoid arthritis (RA). Platelets participate in the regulation of inflammatory processes by the release of pro-inflammatory mediators and platelet-derived microparticles (PMPs). However, the role of the inducible mPGES-1/PGE2 pathway on platelet functions has not been investigated. Here we report a significant impact of mPGES-1 on platelet functions during inflammation...

Our established interleukin-13 ( IL-13 ) overexpression rat model of minimal change-like nephropathy provided a platform to study the molecular signalling pathways in T-helper 2 (Th2) cytokine associated minimal change nephrotic syndrome. We hypothesized that IL-13 may act directly on podocytes, causing podocyte foot process effacement and hence proteinuria in our rat model of minimal change-like nephropathy. This study aimed firstly to delineate the glomerular "gene signature" associated with IL-13-mediated dysregulation of podocyte related proteins, and subsequently to investigate the role of the differentially regulated genes in IL-13-mediated podocyte injury...

BACKGROUND: Pathological cardiac hypertrophy is an independent risk factor of heart failure. However, we still lack effective methods to reverse cardiac hypertrophy. DUSP12 is a member of the DUSP family, which is characterized by its dual specific phosphatase activity to dephosphorylate both tyrosine and serine/threonine residues on one substrate. Some DUSPs have been identified as being involved in the regulation of cardiac hypertrophy. However, the role of DUSP12 during pathological cardiac hypertrophy is still unclear...

Cardiac troponin I (cTnI), a biomarker for myocardial damage and risk stratification, may be involved in the pathogenesis of cardiovascular diseases, which was ascribed to the effect of cTnI auto-antibodies. Whether or not cTnI itself has a direct impact on acute myocardial injury is unknown. To exclude the influence of cTnI antibody on the cardiac infarct size, we studied the effect of cTnI shortly after myocardial ischemia-reperfusion (I/R) injury when cTnI antibodies were not elevated. Pretreatment with cTnI augmented the myocardial infarct size caused by I/R, accompanied by an increase in inflammatory markers in the blood and myocardium...

Chemotherapeutic response is critical for the successful treatment and good prognosis in cancer patients. In this study, we analyzed the gene expression profiles of preoperative samples from ER-negative breast cancer patients with different responses to taxane-anthracycline-based (TA-based) chemotherapy, and identified a group of genes that was predictive. Pregnancy specific beta-1-glycoprotein 1 (PSG1) played a central role within signaling pathways of these genes. Inhibiting the PSG1 can effectively reduce chemoresistance via transforming growth factor-β (TGF-β)-related pathway in ER-negative breast cancer cells...

Current asthma therapies primarily target airway inflammation (AI) and suppress episodes of airway hyperresponsiveness (AHR) but fail to treat airway remodelling (AWR), which can develop independently of AI and contribute to irreversible airway obstruction. This study compared the anti-remodelling and therapeutic efficacy of human bone marrow-derived mesenchymal stem cells (MSCs) to that of human amnion epithelial stem cells (AECs) in the setting of chronic allergic airways disease (AAD), in the absence or presence of an anti-fibrotic (serelaxin; RLX)...

Asthma is a chronic disease of the airways affecting one in ten children in Westernized countries. Recently, our group showed that specific bacterial genera in early life are associated with atopy and wheezing in one-year-old children. However, little is known about the link between the early life gut microbiome and the diagnosis of asthma in preschool age children. To determine the role of the gut microbiota in preschool age asthma, children up to 4 years of age enrolled in the Canadian Healthy Infant Longitudinal Development (CHILD) study were classified as asthmatic (n = 39) or matched healthy controls (n = 37)...

MicroRNAs have been associated with cardiomyocyte apoptosis, a process involved in myocardial remodelling in aortic valve (Av) stenosis (AS). Our aim was to analyse whether the dysregulation of myocardial microRNAs was related to cardiomyocyte apoptosis in AS patients. Endomyocardial biopsies were obtained from 28 patients with severe AS (based on pressure gradients and Av area) referred to Av replacement and from necropsies of 10 cardiovascular disease-free control subjects. AS patients showed an increased ( P <0...

Previous studies have demonstrated a protective effect of the Ang-(1-7)/Mas receptor axis on pathological cardiac hypertrophy. Also, the involvement of Mas receptor in the exercise-induced cardiac hypertrophy has been suggested. However, the role of the Ang-(1-7)/Mas receptor on pregnancy-induced cardiac remodeling remains unknown. The objective of this study was to evaluate the participation of the Mas receptor in the development of the cardiac hypertrophy and fibrosis induced by gestation. Female Wistar rats were shared in 3 groups: control , pregnant , and pregnant treated with Mas receptor antagonist A-779 ...
