Although immunization with MHC class II-restricted ApoB peptides has been shown to be atheroprotective, the mechanism is unclear. Here, we investigated CD4(+) T cell populations in immunized atherosclerotic mice. Peptides (16-mers) from mouse ApoB, the core protein of low-density lipoprotein (LDL), were screened for binding to I-A(b) by computer prediction and confirmed by radiolabeled peptide competition. Three new peptides, P101 (FGKQGFFPDSVNKALY, 5.5 nM IC50), P102 (TLYALSHAVNSYFDVD, 6.8 nM), and P103 (LYYKEDKTSLSASAAS, 95 nM) were tested in an atherosclerosis model (Apoe(-/-) mice on western diet)...

BACKGROUND: A high fat diet has an essential role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). This condition is characterized by hepatic fat accumulation (steatosis) and is associated with obesity, diabetes, and fibrosis or cirrhosis of the liver. Probiotics may be useful in the treatment of steatosis. This study examined the effects of an ingested probiotic formulation on the lipid profiles, liver functions, leptin levels, and inflammatory marker levels of rats with NAFLD that had been induced via high fat and sucrose diet (HFSD)...

BACKGROUND: Obesity is known to be a complex disorder caused by both genetic and environmental factors. Patients with obesity tend to develop cardiovascular disease and type 2 diabetes. Previous studies have revealed that obesity is associated with genetic variations including those found in the apolipoprotein E (APOE) gene, which also affects lipid profiles. Hence, in this study, we aimed to perform a molecular characterization of APOE gene polymorphisms found in overweight subjects within a Saudi population...

PURPOSE: Xanthine oxidase catalyzes the oxidation of xanthine to uric acid. This process generates excessive reactive oxygen species (ROS) that play an important role in atherogenesis. Recent studies show that LRR and PYD domains-containing protein 3 (NLRP3), a component of the inflammasome, may be involved in the formation of foam cells, a hallmark of atherosclerosis. This study was designed to study the role of various scavenger receptors and NLRP3 inflammasome in xanthine oxidase and uric acid-induced foam cell formation...

The persistence of cholesterol-engorged macrophages (foam cells) in the artery wall fuels the development of atherosclerosis. However, the mechanism that regulates the formation of macrophage foam cells and impedes their emigration out of inflamed plaques is still elusive. Here, we report that adhesion receptor CD146 controls the formation of macrophage foam cells and their retention within the plaque during atherosclerosis exacerbation. CD146 is expressed on the macrophages in human and mouse atheroma and can be upregulated by oxidized low-density lipoprotein (oxLDL)...

BACKGROUND: Hypercholesterolemias are known risk factors for cardiovascular diseases. Although statins have reduced the cardiovascular morbidity and mortality and further therapeutic measures are available, treatment goals are often not achieved. In cases of very high levels of low-density lipoprotein (LDL) cholesterol or of intolerability, the established therapies are often not sufficiently effective or cannot be used in adequate doses. For these high-risk patients further treatment options are required...

Antioxidants are substances that may protect cells from the damage caused by unstable molecules such as free radicals. Flavonoids are phenolic substances widely found in fruits and vegetables. The previous studies showed that the ingestion of flavonoids reduces the risk of cardiovascular diseases, metabolic disorders, and certain types of cancer. These effects are due to the physiological activity of flavonoids in the reduction of oxidative stress, inhibiting low-density lipoproteins oxidation and platelet aggregation, and acting as vasodilators in blood vessels...

Multiple lines of evidence suggest that the physiologically normal levels of low-density lipoprotein cholesterol (LDL-C) and the thresholds for development of atherosclerosis and adverse coronary events are in the 30- to 70-mg/dl range. More patients have been studied in randomized controlled trials assessing the effects of statins on outcomes than any other drug class in the history of medicine. This cumulative body of evidence documents that atherosclerosis progression is halted and coronary heart disease events are minimized when statin therapy with or without ezetimibe, and possibly proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, is used to drive down the LDL-C to a range of about 30 to 50 mg/dl...

Familial hypercholesterolemia (FH) is characterized by high low-density lipoprotein (LDL) cholesterol with co-dominant transmission and high risk of cardiovascular disease (CVD), although with high variability among subjects. Currently, CVD stratification tools for heterozygous FH (HeFH) are not available. A definition of severe HeFH has been recently proposed by the International Atherosclerosis Society (IAS), but it has not been validated. Our study aims to see clinical characteristics and prevalence of CVD in subjects defined as severe HeFH by IAS criteria...

PineXol, extracted from Korean red pine bark, has beneficial effects, such as antioxidant, anti3 inflammatory, and anti-lipogenic activities in vitro. We tested the hypothesis that PineXol supplementation could have anti-obesity effects on mice fed a high-fat diet (HFD). Four-week old male C57BL/6 mice were fed normal chow (18% kcal from fat) or HFD (60% kcal from fat). HFD-fed animals were also subjected to PineXol treatment at a dose of 10 or 50 mg/kg body weight (BW) (PX10 or PX50, respectively) body weight...
