BACKGROUND: The inflammatory process in aortic valvular stenosis persists after surgery to replace the valve in almost half of the patients. No association has been found to its persistence. The main objective of this study was to evaluate the inflammatory response in patients with aortic stenosis through the determination of several biomarkers in plasma measured before and after the valvular replacement and to seek an association with the type of prosthesis used. METHODS: This is an observational study with a follow up of 6 months in subjects with severe aortic stenosis...

We recently reported that cholesterol crystals form in hepatocyte lipid droplets (LDs) in human and experimental NASH. Herein, we assigned wild-type C57BL/6J mice to a high-fat (15%) diet for 6 months supplemented with 0%, 0.25%, 0.5%, 0.75%, or 1% dietary cholesterol. Increasing dietary cholesterol led to cholesterol loading of the liver, but not adipose tissue, resulting in fibrosing steatohepatitis at a dietary cholesterol concentration ≥0.5%, whereas mice on lower cholesterol diets developed only simple steatosis...

The origin of multiple myeloma depends on interactions with stromal cells in the course of normal B-cell differentiation and evolution of immunity. The concept of the present study is that genes involved in MM pathogenesis, such as immune response genes, can be identified by screening for single-nucleotide polymorphisms (SNPs) involved in the immune response and a subsequent statistical analysis that focusses on the association of SNPs, certain haplotypes or SNP-SNP interactions with MM risk and prognosis. We genotyped 348 Danish patients and 355 controls for 13 SNPs located in the TNFA, IL-4, IL-6, IL-10 and CHI3L1 gene promoters...

The anti-steatotic and anti-inflammatory effects of fruit water extract (FW) and seed ethanol extract (SE) of Hovenia dulcis Thunb. in chronic alcohol-fed rats were investigated. Rats were fed a liquid diet containing 36% calories from alcohol and orally administered FW or SE (300 and 500mg/kg/day). Both FW and SE reduced hepatic lipid contents and droplets, serum lipid concentration and inflammatory markers (hs-CRP, TNF-α and IL-6) levels compared with the alcohol control group. Alcohol led to significant decreases in the hepatic fatty acid oxidative gene (Ppargc1a, Cpt1a and Acsl1) levels, while it significantly increased the Myd88 and Tnfa gene levels...

Controversial information is available regarding the feed efficiency-related variation in intestinal size, structure and functionality in pigs. The present objective was therefore to investigate the differences in visceral organ size, intestinal morphology, mucosal enzyme activity, intestinal integrity and related gene expression in low and high RFI pigs which were reared at three different geographical locations (Austria, AT; Northern Ireland, NI; Republic of Ireland, ROI) using similar protocols. Pigs (n = 369) were ranked for their RFI between days 42 and 91 postweaning and low and high RFI pigs (n = 16 from AT, n = 24 from NI, and n = 60 from ROI) were selected...

Somatosensory information from the periphery is routed to the spinal cord through centrally-projecting sensory axons that cross into the central nervous system (CNS) via the dorsal root entry zone (DREZ). The glial cells that ensheath these axons ensure rapid propagation of this information. Despite the importance of this glial-axon arrangement, how this afferent nerve is assembled during development is unknown. Using in vivo, time-lapse imaging we show that as centrally-projecting pioneer axons from dorsal root ganglia (DRG) enter the spinal cord, they initiate expression of the cytokine TNFalpha...

Viral infections of the ovary may perturb ovarian functions. However, the mechanisms underlying innate immune responses in the ovary are poorly understood. The present study demonstrates that cytosolic viral DNA sensor signaling initiates the innate immune response in mouse ovarian granulosa cells and affects endocrine function. The cytosolic DNA sensors p204 and cGAS and their common signaling adaptor stimulator of interferon (IFN) genes (STING) were constitutively expressed in granulosa cells. Transfection with VACV70, a synthetic vaccinia virus (VACV) DNA analogue, induced the expression of type I interferons (IFNA/B) and major inflammatory cytokines (TNFA and IL6) through IRF3 and NF-κB activation, respectively...

Chronic intramyocardial inflammation (inflammatory cardiomyopathy/DCMi) is linked to the pathogenesis of dilated cardiomyopathy (DCM). Neural cell adhesion molecule (NCAM) is involved in orchestrating cardiac muscle morphogenesis, but is down-regulated after embryogenesis. We investigated NCAM expression in adult DCM hearts, its possible association with DCMi-parameters, and with cardiomyocyte hypertrophy (CMH). Endomyocardial biopsies (EMBs) from DCM patients (n=85; n=37 females; age: 48±19years; LVEF <40%) and controls from non-cardiac deaths were immunostained for DCMi markers and for NCAM expression, and quantified by digital image analysis (DIA)...

Vaccine development against extracellular bacteria has been important for the sustainability of the aquaculture industry. In contrast, infections with intracellular pathogens remain largely an unresolved problem. Francisella noatunensis subspecies orientalis (Fno) are Gram-negative, facultative intracellular bacteria that cause the disease francisellosis in fish. Francisellosis is commonly characterized as a chronic granulomatous disease with high morbidity and can result in high mortality depending on the host...

BACKGROUND: We reported that some, but not all single nucleotide polymorphisms (SNPs) in select immune response genes are associated with prostate cancer, but not individually with the prevalence of intraprostatic inflammation in the Prostate Cancer Prevention Trial (PCPT) placebo arm. Here, we investigated whether these same SNPs are associated with risk of lower- and higher-grade prostate cancer in men randomized to finasteride, and with prevalence of intraprostatic inflammation among controls...

Head and neck (H&N) cancer is an aggressive disease and the incidence has increased in younger population worldwide. Tumour TNM staging is the main basis for treatment decision despite significant variation in clinical outcome. Survival time of these patients has marginally improved during the last 30 years. Various biomarkers with cumbersome analysis, high cost, time consumption and requirement of special laboratory facilities have been investigated. However, none of these biomarkers have been shown to be suitable to use for individual H&N cancer patient treatment selection in the clinic...

Helminthiasis may ameliorate inflammatory diseases, such as inflammatory bowel disease and asthma. Information about immunomodulators from Ascaris lumbricoides is scarce, but could be important considering the co-evolutionary relationships between helminths and humans. We evaluated the immunomodulatory effects of a recombinant cystatin from A. lumbricoides on an acute model of dextran sodium sulphate (DSS)-induced colitis in mice. From an A. lumbricoides cDNA library, we obtained a recombinant cystatin (rAl-CPI)...

Biliary atresia is an obstructive cholangiopathy of infancy that progresses to end-stage cirrhosis. Although the pathogenesis of the disease is not completely understood, previous reports link TNFα to apoptosis of the bile duct epithelium in the presence of IFNγ. Here, we investigate if TNFα signaling regulates pathogenic mechanisms of biliary atresia. First, we quantified the expression of TNFA and its receptors TNFR1 and TNFR2 in human livers and found an increased expression of the receptors at the time of diagnosis...
