Abstract
Atherosclerosis is one type of cardiovascular disease (CVD) in which activation of the NLRP3 inflammasome and toll-like receptor (TLR) pathways is implicated. One of the most effective treatments for atherosclerosis is the use of statin medications. Recent studies have indicated that statins, in addition to their lipid-lowering effects, exert inhibitory and/or stimulatory effects on the NLRP3 inflammasome and TLRs. Some of the statins lead to activation of the inflammasome and subsequently cause secretion of IL-1β and IL-18. Thus, these actions may further aggravate the disease. On the other hand, some statins cause inhibition of the inflammasome or TLRs and along with lipid-lowering, help to improve the disease by reducing inflammation. In this article, we discuss these contradictory studies and the mechanisms of action of statins on the NLRP3 inflammasome and TLR pathways. The dose-dependent effects of statins on the NLRP3 complex are related to their chemistry, pharmacokinetic properties, and danger signals. Lipophilic statins have more pleiotropic effects on the NLRP3 complex in comparison to hydrophilic statins. Statins can suppress TLR4/MyD88/NF-ĸB signaling and cause an immune response shift to an anti-inflammatory response. Furthermore, statins inhibit the NF-ĸB pathway by decreasing the expression of TLRs 2 and 4. Statins are cost-effective drugs, which should have a continued future in the treatment of atherosclerosis due to both their immune-modulating and lipid-lowering effects.

Abstract
OBJECTIVE The aim of this study is to investigate the molecular mechanisms and effect of rosuvastatin on adhesion molecule induction in human endothelial cells under high-glucose conditions (HG). METHODS AND RESULTS The effects of rosuvastatin on vascular cell adhesion molecule (VCAM)-1 production and pERK phosphorylation were measured in HG-induced human umbilical vein endothelial cells (HUVECs) with inhibitors targeting the mitogen-activated protein kinase (MAPK) signal pathway. HG increased levels of VCAM-1. Treatment with rosuvastatin inhibited VCAM-1 expression in a concentration- and time-dependent manner. In addition, we investigated the effects of rosuvastatin on the extracellular signal-regulated kinase (ERK) 1/2 signal pathway. Rosuvastatin completely inhibited HG-induced phosphorylation of ERK. ERK/MAPK inhibitors completely prevented the VCAM-1 inhibition effect of rosuvastatin under HG condition. CONCLUSIONS This study demonstrated that rosuvastatin suppresses HG-induced VCAM-1 production via the MAPK signalling pathway, playing a role in the suppression of atherosclerosis.

Abstract
Supplemental Digital Content is available in the text. Objective— Rosuvastatin has been widely used in the primary and secondary prevention of coronary heart disease. However, its antiatherosclerotic properties have not been tested in a mouse model that could mimic human coronary heart disease. The present study was designed to test the effects of rosuvastatin on coronary artery atherosclerosis and myocardial fibrosis in SR-B1 (scavenger receptor class B type 1) and apoE (apolipoprotein E) double knockout mice. Approach and Results— Three-week-old SR-B1−/−/apoE−/− mice were injected daily with 10 mg/kg of rosuvastatin for 2 weeks. Compared with saline-treated mice, rosuvastatin-treated mice showed increased levels of hepatic PCSK9 (proprotein convertase subtilisin/kexin type-9) and LDLR (low-density lipoprotein receptor) message, increased plasma PCSK9 protein but decreased levels of hepatic LDLR protein and increased plasma total cholesterol associated with apoB (apolipoprotein B) 48-containing lipoproteins. In spite of this, rosuvastatin treatment was associated with decreased atherosclerosis in both the aortic sinus and coronary arteries and reduced platelet accumulation in atherosclerotic coronary arteries. Cardiac fibrosis and cardiomegaly were also attenuated in rosuvastatin-treated SR-B1−/−/apoE−/− mice. Two-week treatment with rosuvastatin resulted in significant decreases in markers of oxidized phospholipids in atherosclerotic plaques. In vitro analysis showed that incubation of bone marrow-derived macrophages with rosuvastatin substantially downregulated cluster of differentiation (CD)36 and inhibited oxidized LDL-induced foam cell formation. Conclusions— Rosuvastatin protected SR-B1−/−/apoE−/− mice against atherosclerosis and platelet accumulation in coronary arteries and attenuated myocardial fibrosis and cardiomegaly, despite increased plasma total cholesterol. The ability of rosuvastatin to reduce oxidized phospholipids in atherosclerotic plaques and inhibit macrophage foam cell formation may have contributed to this protection.

Abstract
BACKGROUND In animal models and clinical trials, statins are reported as effective in reducing cholesterol levels and lowering the risk of cardiovascular diseases. We have aggregated the findings in animal models - mice, rats and rabbits - using the technique of systematic review and meta-analysis to highlight differences in the efficacy of statins. MATERIALS AND METHODS We searched Medline and Embase. After examining all eligible articles, we extracted results about total cholesterol and other blood parameters, blood pressure, myocardial infarction and survival. Weighted and standard mean difference random effects meta-analysis was used to measure overall efficacy in prespecified species, strains and subgroups. RESULTS We included in systematic review 161 animal studies and we analysed 120 studies, accounting for 2432 animals. Statins lowered the total cholesterol across all species, although with large differences in the effect size: -30% in rabbits, -20% in mice and -10% in rats. The reduction was larger in animals fed on a high-cholesterol diet. Statins reduced infarct volume but did not consistently reduce the blood pressure or effect the overall survival. Few studies considered strains at high risk of cardiovascular diseases or hard outcomes. CONCLUSIONS Although statins showed substantial efficacy in animal models, few preclinical data considered conditions mimicking human pathologies for which the drugs are clinically indicated and utilized. The empirical finding that statins are more effective in lowering cholesterol derived from an external source (i.e. diet) conflicts with statin's supposed primary mechanism of action.

Abstract
Mutations in the NF1 tumor suppressor gene cause Neurofibromatosis type 1 (NF1). Neurofibromin, the protein product of NF1, functions as a negative regulator of Ras activity. Some NF1 patients develop cardiovascular disease, which represents an underrecognized disease complication and contributes to excess morbidity and mortality. Specifically, NF1 patients develop arterial occlusion resulting in tissue ischemia and sudden death. Murine studies demonstrate that heterozygous inactivation of Nf1 (Nf1(+/-)) in bone marrow cells enhances neointima formation following arterial injury. Macrophages infiltrate Nf1(+/-) neointimas, and NF1 patients have increased circulating inflammatory monocytes in their peripheral blood. Therefore, we tested the hypothesis that heterozygous inactivation of Nf1 in myeloid cells is sufficient for neointima formation. Specific ablation of a single copy of the Nf1 gene in myeloid cells alone mobilizes a discrete pro-inflammatory murine monocyte population via a cell autonomous and gene-dosage dependent mechanism. Furthermore, lineage-restricted heterozygous inactivation of Nf1 in myeloid cells is sufficient to reproduce the enhanced neointima formation observed in Nf1(+/-) mice when compared with wild-type controls, and homozygous inactivation of Nf1 in myeloid cells amplified the degree of arterial stenosis after arterial injury. Treatment of Nf1(+/-) mice with rosuvastatin, a stain with anti-inflammatory properties, significantly reduced neointima formation when compared with control. These studies identify neurofibromin-deficient myeloid cells as critical cellular effectors of Nf1(+/-) neointima formation and propose a potential therapeutic for NF1 cardiovascular disease.

Abstract
BACKGROUND AND PURPOSE HMG-CoA reductase inhibitors, statins, with lipid-reducing properties combat against atherosclerosis and diabetes. The favourable modulation of endothelial function may play a significant role in this effect. The present study aimed to investigate the cellular mechanisms responsible for the therapeutic benefits of rosuvastatin in ameliorating diabetes-associated endothelial dysfunction. EXPERIMENTAL APPROACH Twelve-week-old db/db diabetic mice were treated with rosuvastatin at 20 mg·kg⁻¹ ·day⁻¹ p.o.for 6 weeks. Isometric force was measured in isolated aortae and renal arteries. Protein expressions including angiotensin II type 1 receptor (AT₁R), NOX4, p22(phox) , p67(phox) , Rac-1, nitrotyrosine, phospho-ERK1/2 and phospho-p38 were determined by Western blotting, while reactive oxygen species (ROS) accumulation in the vascular wall was evaluated by dihydroethidium fluorescence and lucigenin assay. KEY RESULTS Rosuvastatin treatment of db/db mice reversed the impaired ACh-induced endothelium-dependent dilatations in both renal arteries and aortae and prevented the exaggerated contractions to angiotensin II and phenylephrine in db/db mouse renal arteries and aortae. Rosuvastatin reduced the elevated expressions of AT₁R, p22(phox) and p67(phox) , NOX4, Rac1, nitrotyrosine and phosphorylation of ERK1/2 and p38 MAPK and inhibited ROS production in aortae from db/db mice. CONCLUSIONS AND IMPLICATIONS The vasoprotective effects of rosuvastatin are attributed to an increase in NO bioavailability, which is probably achieved by its inhibition of ROS production from the AT₁R-NAD(P)H oxidase cascade.

Abstract
The purpose of this study was to investigate the short-term effects of rosuvastatin (RSV), a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, on transient, focal cerebral ischemia in C57BL/6J ob/ob mice with insulin resistance (IR). Male ob/ob, lean, or wild-type (WT) mice were treated with RSV (10 mg/kg per day, i.p.) or vehicle for 3 days. Ischemia was induced by 60 mins of middle cerebral artery occlusion (MCAO) and cortical blood flow (CBF) was monitored by laser-Doppler flowmetry. Infarct volumes were measured 24 h after reperfusion. IR mice exhibited a higher infarct volume compared with Lean or WT mice, and RSV reduced infarct volume only in obese mice (40%+/-3% versus 32%+/-3%, P<0.05). Blood cholesterol and insulin levels were elevated in ob/ob mice but were unaffected by RSV. The CBF reductions during MCAO were similar in all groups and were not affected by RSV. Although RSV did not increase cortical endothelial NO synthase (eNOS) levels in the ob/ob mice, it attenuated the increased cortical expression of intracellular adhesion molecule-1 (ICAM-1) after MCAO from ob/ob mice. Thus, RSV protects against stroke in IR mice by a mechanism independent of effects on the lipid profile, CBF, or eNOS but dependent on suppression of post-MCAO ICAM-1 expression.

Abstract
Statins, in addition to their beneficial lipid modulation effects, exert a variety of several so-called "pleiotropic" actions that may result in clinical benefits. Rosuvastatin, the last agent of the class to be introduced, has proved remarkably potent in reducing low-density lipoprotein cholesterol levels. At present, no large-scale primary or secondary prevention clinical trials document either its long-term safety or its effectiveness in preventing cardiovascular events. A substantial number of experimental and clinical studies have indicate favorable effects of rosuvastatin on endothelial function, oxidized low-density lipoprotein, inflammation, plaque stability, vascular remodeling, hemostasis, cardiac muscle, and components of the nervous system. Available data regarding the effects of rosuvastatin on renal function and urine protein excretion do not seem to raise any safety concerns. Whether the established "pleiotropy" and/or lipid-lowering efficacy of rosuvastatin may translate into reduced morbidity and mortality remains to be shown in ongoing clinical outcome trials.

Abstract
In diabetes the exposure of the vascular endothelium to high glucose levels results in increased oxidative insult and in vascular dysfunction. We have investigated the effects of rosuvastatin on oxidative stress and apoptosis induced in human umbilical vein endothelial cells (HUVECs) by constant and intermittent high glucose levels. HUVECs were incubated for 14 days in either low (5 mM) or high (20 mM) glucose concentrations, or intermittent high and low glucose on a daily basis. Constant high glucose levels increased p47-phox, p67-phox, and p22-phox expression [components of the Nicotinamide adenine dinucleotide phosphate [NAD(P)H] oxidase complex]; endothelial nitric oxide synthase, nitric oxide, and O(2)(-) production; nitrotyrosine, 8-hydroxy-2'-deoxyguanosine, and caspase-3 expression; and reduced Bcl-2 expression. These effects were significantly greater under intermittent compared to constant high/low glucose conditions. The effect of rosuvastatin (1 microM) in the presence or absence of mevalonate (200 microM) was evaluated in the cells under both constant and intermittent glucose conditions. Rosuvastatin almost normalized all these parameters. These effects of rosuvastatin were prevented when mevalonate was also added, demonstrating the link to inhibition of 3-hydroxy-3-methylglutaryl coenzyme A reductase. These data suggest that rosuvastatin has the potential to prevent damage to and apoptosis of HUVECs induced by high glucose exposure, by reducing oxidative stress. The action of rosuvastatin on antioxidant pathways is related to the inhibition of the overexpression of components of NAD(P)H oxidase induced by the two conditions of high glucose.

Abstract
Traumatic brain injury (TBI) triggers a complex sequence of inflammatory responses that contribute to secondary injury. Statins have demonstrated neuroprotective effects against brain injury, but the underlying mechanisms remain unclear. This study evaluated the effects of lovastatin on a rat model of controlled cortical impact (CCI) injury. Our two hypotheses were that pre-administration of lovastatin would reduce functional deficits and extent of anatomical brain damage and that lovastatin would attenuate levels of pro-inflammatory cytokines. Rats were injected with lovastatin (4 mg/kg) or vehicle for 5 days and subjected to CCI. Neurological status was evaluated using rotarod and adhesive removal tests. Contusion volume and neuronal degeneration were examined using cresyl violet and FluoroJade B (FJB) histochemistry. Levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) mRNA and protein were assessed by real-time quantitative reverse transcriptase polymerase chain reaction, enzyme-linked immunosorbent assay, and immunohistochemistry. Lovastatin significantly improved performance on both the rotarod and adhesive removal tests before post-injury day 7. Lovastatin also significantly reduced contusion volume (20%) and number of FJB-positive degenerating neurons (35%) at 4 days. These changes were associated with a significant decrease in levels of TNF-alpha and IL-1beta mRNA and protein at the contusion site at 6 h and 4 days, respectively. Our results show that pre-administration of lovastatin improved functional outcomes and reduced extent of brain damage, with a concomitant decrease in tissue levels of TNF-alpha and IL-1beta mRNA and protein. These findings suggest that lovastatin's protective mechanisms may be partly attributed to a dampening of the inflammatory response.

Abstract
BACKGROUND Rosuvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, has pleiotropic effects that are anti-inflammatory and antiatherothrombotic. It is important to understand the cardioprotective effects of rosuvastatin in order to optimize its additional advantages in the treatment and prevention of cardiovascular diseases. METHODS Human umbilical vein endothelial cells (HUVEC) were treated with tumor necrosis factor (TNF)-alpha (10 ng/mL) alone or with rosuvastatin (100 microM). The extent of inflammation was determined by U937 adhesion assay as well as analysis of the expression of intercellular adhesion molecule (ICAM)-1, monocyte chemoattractant protein (MCP)-1, interleukin (IL)-8, IL-6, cyclooxygenase (COX)-2, c-Jun N-terminal kinase (JNK), extracellular signal-regulated protein kinase (ERK), p38, and signal transducer and activator of transcription (STAT)-3. The activation of nuclear factor kappa B (NF-kappaB) was determined by Western blot. RESULTS Rosuvastatin decreased the extent of U937 adhesion to TNF-alpha-stimulated HUVEC. Rosuvastatin inhibited the expressions of ICAM-1, MCP-1, IL-8, IL-6, and COX-2 mRNA and protein levels. The activation of JNK and NF-kappaB was also blocked by rosuvastatin. The inhibitors of JNK, NF-kappaB, and STAT-3 produced a statistically significant decrease of the TNF-alpha induced U937 adhesion and IL-6 protein release. CONCLUSIONS This study suggests that the anti-inflammatory activity of rosuvastatin is accompanied by the inhibition of JNK and NF-kappaB.

Abstract
Low-density lipoprotein (LDL) has been implicated in the initiation and progression of atherosclerotic vascular disease. But whether LDL can elicit similar effects in the microcirculation remain unexplored. To approach this issue, the hypothesis that LDL promotes oxidative stress in monocytes and results in microvascular inflammation was tested. Native LDL was capable of stimulating respiratory burst in rat monocytes, and this was blocked by BAPTA, cytochalasin B, apocynin, and diphenyliodonium. In monocytes from rats on a high-cholesterol (4%) diet, increased intracellular calcium, actin polymerization, respiratory burst, and surface CD18 expression were found. Concurrently, leukocyte-endothelial interaction was enhanced in the cremaster microcirculation. Rosiglitazone, an insulin-sensitizing agent with antiinflammatory properties, was found to suppress native-LDL-induced actin polymerization and respiratory burst in monocytes. It also improved leukocytes activation and leukocyte-endothelial interaction due to the high cholesterol intake. Hence, native LDL stimulation of monocytes contributed to hypercholesterolemia-associated microvascular inflammation, which could be treated by rosiglitazone.

Abstract
Statins reduce cholesterol synthesis and are widely used for the treatment of hyperlipidaemia and ischaemic heart disease. Besides their cholesterol-lowering effects, statins also possess broad immunomodulatory and anti-inflammatory properties. Vascular endothelial cells have a crucial role in the pathogenesis of inflammatory disease, and, alongside leukocytes and antigen-presenting cells, represent a key cellular target for statin therapy. Recent studies investigating how these drugs modify endothelial cell function demonstrate that the therapeutic effect of statins can be attributed, in part, to their action on the endothelium. Accordingly, statins attenuate endothelial MHC class II expression, increase endothelial nitric oxide synthase and fibrinolytic activity, decrease leukocyte adhesion and transmigration, and enhance resistance to local injurious stimuli. Many of these effects are brought about by the modulation of small GTPase function and the downregulation of proinflammatory gene expression.

Abstract
Statins possess anti-inflammatory effects that may contribute to their ability to slow atherogenesis, whereas nitric oxide (NO) also influences inflammatory cell adhesion. This study aimed to determine whether a novel NO-donating pravastatin derivative, NCX 6550 [(1S-[1alpha(betaS*,deltaS*),2alpha,6alpha,8beta-(R*),8a alpha]]-1,2,6,7,8,8a-hexahydro-beta,delta,6-trihydroxy-2-methyl-8-(2-methyl-1-oxobutoxy)-1-naphthalene-heptanoic acid 4-(nitrooxy)butyl ester)], has greater anti-inflammatory properties compared with pravastatin in normal and atherosclerotic apolipoprotein E receptor knockout (ApoE-/-) mice. C57BL/6 and ApoE-/- mice were administered pravastatin (40 mg/kg), NCX 6550 (48.5 mg/kg), or vehicle orally for 5 days. Ex vivo studies assessed splenocyte adhesion to arterial segments and splenocyte reactive oxygen species (ROS) generation. NCX 6550 significantly reduced splenocyte adhesion to artery segments in both C57BL/6 (8.8 +/- 1.9% versus 16.6 +/- 6.7% adhesion; P < 0.05) and ApoE-/- mice (9.3 +/- 2.9% versus 23.4 +/- 4.6% adhesion; P < 0.05) concomitant with an inhibition of endothelial intercellular adhesion molecule-1 expression. NCX 6550 also significantly reduced phorbol 12-myristate 13-acetate-induced ROS production that was enhanced in isolated ApoE-/- splenocytes. Conversely, pravastatin had no significant effects on adhesion in normal or ApoE-/- mice but reduced the enhanced ROS production from ApoE-/- splenocytes. In separate groups of ApoE-/- mice, NCX 6550 significantly enhanced endothelium-dependent relaxation to carbachol in aortic segments precon-tracted with phenylephrine (-logEC(50), 6.37 +/- 0.37) compared with both vehicle-treated (-logEC50, 5.81 +/- 0.15; P < 0.001) and pravastatin-treated (-logEC50, 5.57 +/- 0.45; P < 0.05) mice. NCX 6550 also significantly reduced plasma monocyte chemoattractant protein-1 levels (648.8 pg/ml) compared with both vehicle (1191.1 pg/ml; P < 0.001) and pravastatin (847 +/- 71.0 pg/ml; P < 0.05) treatment. These data show that NCX 6550 exerts superior anti-inflammatory actions compared with pravastatin, possibly through NO-related mechanisms.

Abstract
Members of the immunoglobulin superfamily of endothelial adhesion molecules, vascular cell adhesion molecule (VCAM-1) and intercellular cell adhesion molecule (ICAM- 1), strongly participate in leukocyte adhesion to the endothelium and play an important role in all stages of atherogenesis. The aim of this study was to detect and quantify the changes of endothelial expression of VCAM-1, and ICAM-1 in the vessel wall after the short-term administration of simvastatin, atorvastatin, and micro dispersed derivatives of oxidised cellulose (MDOC) in apolipoprotein-E-deficient (apoE(-/-)) mice atherosclerotic model. Hyperlipidemic apoE(-/-) mice (n = 32) received normal chow diet or diet containing simvastatin or atorvastatin 10 mg/kg/day or MDOC 50 mg/kg/day. Total cholesterol, VLDL, LDL, HDL and TAG were measured and the endothelial expression of VCAM-1 and ICAM-1 was visualized and quantified by means of immunohistochemistry and stereology, respectively. Total cholesterol levels was insignificantly lowered only in MDOC treated mice but not in mice treated with statins. ICAM-1 endothelial expression was not affected by neither simvastatin nor MDOC treatment. However, significant diminution of VCAM-1 endothelial expression was observed in both atorvastatin and MDOC treated mice. These results provide new information of potential hypolipidemic substance MDOC and its potential anti-inflammatory effects. Furthermore, we have confirmed anti-inflammatory effects of atorvastatin independent of plasma cholesterol lowering. Thus, the results of this study show potential benefit of both MDOC and atorvastatin treatment in apoE(-/-) mouse model of atherosclerosis suggesting their possible combination might be of interest.

Abstract
In humans, hypercholesterolemia, steatohepatitis, and risk for arteriosclerosis are associated. Apolipoprotein E-deficient mice, a widely used animal model, show both arteriosclerosis and steatohepatitis in response to high-fat and cholesterol diets. We have found a relationship between these conditions and a higher mRNA aortic and hepatic monocyte chemoattractant protein-1 (mcp-1) gene expression. Both tissues respond in a similar way when dietary cholesterol is provided for a few weeks but differently if the conditions persist for a protracted period of time. After 8 months of treatment, the mcp-1 gene expression in the aorta continues increasing but in the liver decreases. This coincides with a significant increase in hepatic ppar-delta anti-inflammatory gene expression. Apparently, the arterial wall cannot prevent the deleterious effects of higher mcp-1 expression by increasing ppar-delta gene expression and the lesion progress. However, in the liver, the activation of anti-inflammatory genes may reduce the hepatic mcp-1 expression which significantly decreases the inflammatory response. This differential inflammatory gene expression in aorta and liver may support the idea that anti-inflammatory transcription factors are involved in the response to diet and inflammation. Therefore, the use of cholesterol-enriched diets should be carefully considered in the apolipoprotein E-deficient mice because they may trigger different stimuli and seriously hinder the interpretation of possible findings.

Abstract
INTRODUCTION Earlier we have demonstrated a prothrombotic state in spontaneously atherogenic rodents kept on Western-style high fat diet. The aim of the present study was to investigate the cellular mechanism of such prothrombotic state. MATERIALS AND METHODS Two kinds of diets, Western-style high fat diet containing 20% fat (w/w) and 0.05% cholesterol (w/w) and low fat diet containing 7% fat without cholesterol based on AIN93G, were added to diet-sensitive apolipoprotein E and low-density lipoprotein receptor double deficient male mice for 12 or 18 weeks from 6 weeks of age. Atherosclerosis was assessed by morphometry of the aortic wall or lipid-stained lesions. Endothelial function was measured by flow-mediated vasodilation (FMV) of the femoral artery. Platelet reactivity was measured ex vivo by a shear-induced platelet aggregation test. RESULTS AND CONCLUSIONS 12 weeks feeding of mice with high fat diet significantly impaired FMV, as compared with mice fed with low fat diet (P<0.05). In contrast, there was no significant difference in the lipid-stained areas and in the reactivity of platelets between the two groups. 18 weeks feeding with high fat diet significantly impaired FMV (P<0.05) and enhanced both lipid-stained areas (P<0.05) and platelet reactivity (P<0.01). These findings show that in high fat diet-induced prothrombotic state, endothelial dysfunction precedes both the morphologically detectable lesions and the enhancement of platelet reactivity.
