NF-B-mediated metabolic remodelling in the inflamed heart in acute viral myocarditis

Acute viral myocarditis (VM), characterised by leukocyte infiltration and dysfunction of the heart, is an important cause of sudden cardiac death in young adults. Unfortunately, to date, the pathological mechanisms underlying cardiac failure in VM remain incompletely understood. In the current study, we investigated if acute VM leads to cardiac...

Inflammatory cytokine oncostatin M induces endothelial activation in macro- and microvascular endothelial cells and in APOE*3Leiden.CETP mice

Aims Endothelial activation is involved in many chronic inflammatory diseases, such as atherosclerosis, and is often initiated by cytokines. Oncostatin M (OSM) is a relatively unknown cytokine that has been suggested to play a role in both endothelial activation and atherosclerosis. We comprehensively investigated the effect of OSM on...

A dietary mixture containing fish oil, resveratrol, lycopene, catechins, and vitamins E and C reduces atherosclerosis in transgenic mice

Chronic inflammation and proatherogenic lipids are important risk factors of cardiovascular disease (CVD). Specific dietary constituents such as polyphenols and fish oils may improve cardiovascular risk factors and may have a beneficial effect on disease outcomes. We hypothesized that the intake of an antiinflammatory dietary mixture (AIDM)...

LXR agonist suppresses atherosclerotic lesion growth and promotes lesion regression in apoE*3Leiden mice: Time course and mechanisms

The aim of this study was to define the anti-atherosclerotic role of liver-X-receptors (LXRs) under lesion progressive and lesion regressive conditions, to establish a temporal line of events, and to gain insights into the mechanisms underlying the anti-atherogenic potency of LXRs. We used apoE*3Leiden (E3L) mice to comprehensively and time...

Alcohol consumption, mediating biomarkers, and risk of type 2 diabetes among middle-aged women

OBJECTIVE - The purpose of this study was to investigate whether adiponectin concentrations and biomarkers of inflammation, endothelial dysfunction, and insulin resistance mediate the association between alcohol consumption and diabetes. RESEARCH DESIGN AND METHODS - In a nested case-control study of 705 women with incident diabetes and 787...

Fenofibrate reduces atherogenesis in ApoE*3Leiden mice: Evidence for multiple antiatherogenic effects besides lowering plasma cholesterol

OBJECTIVE - To demonstrate, quantify, and mechanistically dissect antiatherosclerotic effects of fenofibrate besides lowering plasma cholesterol per se. METHODS AND RESULTS - ApoE*3Leiden transgenic mice received either a high-cholesterol diet (HC) or HC containing fenofibrate (HC+FF) resulting in 52% plasma cholesterol-lowering. In a separate...

Reduction of the aortic inflammatory response in spontaneous atherosclerosis by blockade of macrophage migration inhibitory factor (MIF)

Atherosclerosis is an inflammatory response of the arterial wall to "injury", which is prominently driven by cytokines. The inflammatory mediator macrophage migration inhibitory factor (MIF) is a unique cytokine that was recently associated with atherogenesis. Here, we have investigated whether MIF has a role in spontaneous atherosclerosis by...

Soluble vascular cell adhesion molecule (VCAM) is associated with treatment effects of Interferon beta-1b in patients with Secondary Progressive Multiple Sclerosis

Background: Subcutaneous IFNβ-1b (Betaferon®) is an established immunomodulatory treatment for relapsing remitting MS and active secondary progressive multiple sclerosis (SPMS). It modulates cytokine and adhesion molecule expression but long term in vivo effects of IFNβ-1b on the immune system are not known in multiple sclerosis. Objective: To...

The effect of the food matrix on In Vivo immune responses to purified peanut allergens

There is little knowledge about the factors that determine the allergenicity of food proteins. One aspect that remains to be elucidated is the effect of the food matrix on immune responses to food proteins. To study the intrinsic immunogenicity of allergens and the influence of the food matrix, purified peanut allergens (Ara h 1, Ara h 2, Ara h...

Serum carotenoids and vitamins in relation to markers of endothelial

Background: Endothelial cell dysfunction may be related to an increase in cellular oxidative stress. Carotenoids and vitamins could have an antioxidant-mediated tempering influence on endothelial function and inflammation, thereby reducing the risk of atherosclerosis. Methods: We measured serum carotenoids, α-tocopherol and Vitamin C...

Soluble intercellular adhesion molecule 1 and flow-mediated dilatation are related to the estimated risk of coronary heart disease independently from each other

Background: Flow mediated dilatation (FMD) of the brachial artery and soluble intercellular adhesion molecule 1 (sICAM-1) are measures of distinct functions of the endothelium, reflecting nitric oxide (NO)-mediated and pro-inflammatory status, respectively. The comparative value of the two measures in relation to cardiovascular risk is unknown....

Inflammatory mediators and cell adhesion molecules as indicators of severity of atherosclerosis: The Rotterdam Study

Inflammatory mediators and soluble cell adhesion molecules predict cardiovascular events. It is not clear whether they reflect the severity of underlying atherosclerotic disease. Within the Rotterdam Study, we investigated the associations of C-reactive protein (CRP), interleukin-6 (IL-6), soluble intercellular adhesion molecule-1, and soluble...

Recombinant adenoviral vectors have adjuvant activity and stimulate T cell responses against tumor cells

The host-immune response against adenoviruses forms a major obstacle for their use as gene therapy vectors for treatment of genetic defects. None the less, they are the preferred vectors for in vivo gene transfer in experimental gene therapy protocols for cancer. In this article we demonstrate the antitumor efficacy of adenovirus-mediated...

Progression and regression of atherosclerosis in APOE3-Leiden transgenic mice: An immunohistochemical study

Apolipoprotein E3-Leiden (APOE3-Leiden) transgenic mice develop hyperlipidemia and are highly susceptible to diet-induced atherosclerosis. We have studied the progression and regression of atherosclerosis using immunohistochemistry. Female transgenic mice were fed a moderate fat diet to study atherosclerosis over a longer time period. Fatty...

The role of DNA damage and repair in ultraviolet B radiation-induced immunomodulation: Relevance for human photocarcinogenesis

Chemicals/CAS: Intercellular Adhesion Molecule-1, 126547-89-5; Pyrimidine Dimers

A spontaneous mutation characterized by chronic proliferative dermatitis in C57BL mice

Chronic proliferative dermatitis is a new spontaneous mutation in C57BL/Ka mice. Breeding results suggest an autosomal recessive mode of inheritance. Mutant mice develop skin lesions at the age of 5 to 6 weeks. The lesions occur in the ventral and dorsal skin of the body, whereas ears, footpads, and tail are not involved. The lesions are...
