Abstract
Cerebrovascular diseases and their sequalae, such as ischemic stroke, chronic cerebral hypoperfusion, and vascular dementia are significant contributors to adult disability and cognitive impairment in the modern world. Astrocytes are an integral part of the neurovascular unit in the CNS and play a pivotal role in CNS homeostasis, including ionic and pH balance, neurotransmission, cerebral blood flow, and metabolism. Astrocytes respond to cerebral insults, inflammation, and diseases through unique molecular, morphological, and functional changes, collectively known as reactive astrogliosis. The function of reactive astrocytes has been a subject of debate. Initially, astrocytes were thought to primarily play a supportive role in maintaining the structure and function of the nervous system. However, recent studies suggest that reactive astrocytes may have both beneficial and detrimental effects. For example, in chronic cerebral hypoperfusion, reactive astrocytes can cause oligodendrocyte death and demyelination. In this review, we will summarize the (1) roles of ion transporter cascade in reactive astrogliosis, (2) role of reactive astrocytes in vascular dementia and related dementias, and (3) potential therapeutic approaches for dementing disorders targeting reactive astrocytes. Understanding the relationship between ion transporter cascade, reactive astrogliosis, and cerebrovascular diseases may reveal mechanisms and targets for the development of therapies for brain diseases associated with reactive astrogliosis.

Abstract
Arterial occlusive disease is the leading cause of death in Western countries. Core contemporary therapies for this disease include angioplasties, stents, endarterectomies and bypass surgery. However, these treatments suffer from high failure rates due to re-occlusive vascular wall adaptations and restenosis. Restenosis following vascular surgery is largely due to intimal hyperplasia. Intimal hyperplasia develops in response to vessel injury, leading to inflammation, vascular smooth muscle cells dedifferentiation, migration, proliferation and secretion of extra-cellular matrix into the vessel's innermost layer or intima. In this review, we describe the current state of knowledge on the origin and mechanisms underlying the dysregulated proliferation of vascular smooth muscle cells in intimal hyperplasia, and we present the new avenues of research targeting VSMC phenotype and proliferation.

Abstract
Interleukin (IL)-1β plays an important role in atherosclerosis pathogenesis. We aimed to investigate the effect of anakinra, a recombinant human IL-1 receptor antagonist, on the progression of atherosclerosis in apolipoprotein E knockout (ApoE−/−) mice. ApoE−/− mice (8-week male) were treated with saline (control), anakinra 10, 25, and 50 mg/kg, respectively (n = 10 in each group). Mice were fed a standard chow (4 weeks) followed by an atherogenic diet (35kcal% fat, 1.25% cholesterol, 12 weeks). Atheromatous plaques in ApoE−/− mice and the expression of inflammatory genes and signaling pathways in human umbilical vein endothelial cells (HUVECs), rat aortic smooth muscle cells (RAOSMCs), and 3T3-L1 adipocytes were assessed. Anakinra reduced the plaque size of the aortic arch (30.6% and 25.2% at the 25 mg/kg and 50 mg/kg doses, both p < 0.05) and serum triglyceride in ApoE−/− mice and suppressed inflammatory genes (IL-1β and IL-6) expressions in HUVECs and RAOSMCs (all p < 0.05). In RAOSMCs, anakinra reduced metalloproteinase-9 expression in a dose-dependent manner and inhibited cell migration. Anakinra-treated mice exhibited trends of lower CD68+ macrophage infiltration in visceral fat and monocyte chemoattractant protein-1 expression was reduced in 3T3-L1 adipocytes. Anakinra could be a useful component for complementary treatment with a standard regimen to reduce the residual cardiovascular risk.

Abstract
Obesity is frequently associated with cerebrovascular dysfunction; however, the underlying mechanism remains less well understood. In this study, by using pharmacological approaches, we show that neuroinflammation involving microglia plays an important role in obesity-related cerebrovascular dysfunction. PLX3397 treatment, which leads to depletion of microglia, reduced the wall thickness and collagen deposition in the basilar artery of diet-induced obesity (DIO) mice. Besides, the phosphorylation of endothelial nitric oxide synthase (eNOS) at Ser1177 was enhanced, suggesting improved endothelial function of the basilar artery. The wire myography data show that acetylcholine-elicited relaxation of basilar artery isolated from DIO mice was improved after the treatment with PLX3397. Moreover, our data demonstrate that brain administration of IL-18 impaired cerebrovascular function in mice with normal body weight. Together, these data suggest that neuroinflammation involving microglia is important in obesity-related vascular dysfunction in the brain.NEW & NOTEWORTHY We reported that microglia, the resident immune cells in the brain, contribute to obesity-related cerebrovascular dysfunction in mice. Moreover, we showed that excessive IL-18 can lead to vascular dysfunction in mouse brain.

Age-Dependent and -Independent Effects of Perivascular Adipose Tissue and Its Paracrine Activities during Neointima Formation. Int J Mol Sci 2019; 21:ijms21010282.

Abstract
Cardiovascular risk factors may act by modulating the composition and function of the adventitia. Here we examine how age affects perivascular adipose tissue (PVAT) and its paracrine activities during neointima formation. Aortic tissue and PVAT or primary aortic smooth muscle cells from male C57BL/6JRj mice aged 52 weeks (“middle-aged”) were compared to tissue or cells from mice aged 16 weeks (“adult”). Vascular injury was induced at the carotid artery using 10% ferric chloride. Carotid arteries from the middle-aged mice exhibited smooth muscle de-differentiation and elevated senescence marker expression, and vascular injury further aggravated media and adventitia thickening. Perivascular transplantation of PVAT had no effect on these parameters, but age-independently reduced neointima formation and lumen stenosis. Quantitative PCR analysis revealed a blunted increase in senescence-associated proinflammatory changes in perivascular tissue compared to visceral adipose tissue and higher expression of mediators attenuating neointima formation. Elevated levels of protein inhibitor of activated STAT1 (PIAS1) and lower expression of STAT1- or NFκB-regulated genes involved in adipocyte differentiation, inflammation, and apoptosis/senescence were present in mouse PVAT, whereas PIAS1 was reduced in the PVAT of patients with atherosclerotic vessel disease. Our findings suggest that age affects adipose tissue and its paracrine vascular activities in a depot-specific manner. PIAS1 may mediate the age-independent vasculoprotective effects of perivascular fat.

Abstract
RATIONALE A high incidence of GLA IVS4+919 G>A mutation in patients with Fabry disease of the later-onset cardiac phenotype, has been reported in Taiwan. However, suitable biomarkers or potential therapeutic surrogates for Fabry cardiomyopathy (FC) in such patients under enzyme replacement treatment (ERT) remain unknown. OBJECTIVE Using FC patients carrying IVS4+919 G>A mutation, we constructed an induced pluripotent stem cell (iPSC)-based disease model to investigate the pathogenetic biomarkers and potential therapeutic targets in ERT-treated FC. RESULTS AND METHODS The iPSC-differentiated cardiomyocytes derived from FC-patients (FC-iPSC-CMs) carried IVS4+919 G>A mutation recapitulating FC characteristics, including low α-galactosidase A enzyme activity, cellular hypertrophy, and massive globotriaosylceramide accumulation. Microarray analysis revealed that interleukin-18 (IL-18), a pleiotropic cytokine involved in various myocardial diseases, was the most highly upregulated marker in FC-iPSC-CMs. Meanwhile, IL-18 levels were found to be significantly elevated in the culture media of FC-iPSC-CMs and patients' sera. Notably, the serum IL-18 levels were highly paralleled with the progression of left ventricular hypertrophy in Fabry patients receiving ERT. Finally, using FC-iPSC-CMs as in vitro FC model, neutralization of IL-18 with specific antibodies combined with ERT synergistically reduced the secretion of IL-18 and the progression of cardiomyocyte hypertrophy in FC-iPSC-CMs. CONCLUSION Our data demonstrated that cardiac IL-18 and circulating IL-18 are involved in the pathogenesis of FC and LVH. IL-18 may be a novel marker for evaluating ERT efficacy, and targeting IL-18 might be a potential adjunctive therapy combined with ERT for the treatment of advanced cardiomyopathy in FC patients with IVS4+919 G>A mutation.

Abstract
Inflammatory cells play key roles in restenosis upon vascular surgical procedures such as bypass grafts, angioplasty and stent deployment but the molecular mechanisms by which these cells affect restenosis remain unclear. The p110δ isoform of phosphoinositide 3-kinase (PI3K) is mainly expressed in white blood cells. Here, we have investigated whether p110δ PI3K is involved in the pathogenesis of restenosis in a mouse model of carotid injury, which mimics the damage following arterial grafts. We used mice in which p110δ kinase activity has been disabled by a knockin (KI) point mutation in its ATP-binding site (p110δD910A/D910A PI3K mice). Wild-type (WT) and p110δD910A/D910A mice were subjected to longitudinal carotid injury. At 14 and 30 days after carotid injury, mice with inactive p110δ showed strongly decreased infiltration of inflammatory cells (including T lymphocytes and macrophages) and vascular smooth muscle cells (VSMCs), compared with WT mice. Likewise, PI-3065, a p110δ-selective PI3K inhibitor, almost completely prevented restenosis after artery injury. Our data showed that p110δ PI3K plays a main role in promoting neointimal thickening and inflammatory processes during vascular stenosis, with its inhibition providing significant reduction in restenosis following carotid injury. p110δ-selective inhibitors, recently approved for the treatment of human B-cell malignancies, therefore, present a new therapeutic opportunity to prevent the restenosis upon artery injury.

Abstract
The role of inflammation on atherosclerosis and restenosis is well established. Restenosis is thought to be a complex response to injury, which includes early thrombus formation, acute inflammation and neo-intimal growth. Inflammatory cells are likely contributors in the host response to vascular injury, via cytokines and chemokines secretion, including TNF-alpha (TNF). We have previously shown that IL-10 inhibits TNF and other inflammatory mediators produced in response to cardiovascular injuries. The specific effect of IL-10 on endothelial cell (ECs) biology is not well elucidated. Here we report that in a mouse model of carotid denudation, IL-10 knock-out mice (IL-10KO) displayed significantly delayed Re-endothelialization and enhanced neo-intimal growth compared to their WT counterparts. Exogenous recombinant IL-10 treatment dramatically blunted the neo-intimal thickening while significantly accelerating the recovery of the injured endothelium in WT mice. In vitro, IL-10 inhibited negative effects of TNF on ECs proliferation, ECs cell cycle, ECs-monocyte adhesion and ECs apoptosis. Furthermore, IL-10 treatment attenuated TNF-induced smooth muscle cells proliferation. Our data suggest that IL-10 differentially regulate endothelial and vascular smooth cells proliferation and function and thus inhibits neo-intimal hyperplasia. Thus, these results may provide insights necessary to develop new therapeutic strategies to limit vascular restenosis during percutaneous coronary intervention (PCI) in the clinics.

Abstract
OBJECTIVES Constrictive pericarditis (CP) is an uncommon disease with multiple causes and unclear clinical outcomes. To date, few publications have clearly defined risk factors of poor outcomes after surgery for CP. We performed a retrospective analysis of almost 100 patients undergoing surgical treatment for CP at a single institution in order to identify risk factors for perioperative and long-term mortality. METHODS A total of 97 consecutive patients (67.0% male) undergoing surgery for CP at our institution from 1995 to 2012 were included in the study. CP was diagnosed either preoperatively by cardiac catheterization and appropriate imaging or during surgery. Preoperative and intraoperative risk factors for 30-day and late mortality were analysed using stepwise multivariate logistic and Cox regression analyses. Median follow-up was 1.23 ± 3.96 years (mean 3.08 ± 3.96 years). RESULTS The mean patient age was 60.0 ± 12.5 years and the underlying aetiology was idiopathic (50.5%), prior cardiac surgery (15.5%), prior mediastinal radiation (9.3%), and miscellaneous (24.7%). All patients underwent either radical (55.2%) or partial (44.8%) pericardiectomy. Concomitant procedures were performed in 54 (55.7%) patients. The total procedure time was 197.0 ± 105.0 min. Cardiopulmonary bypass (CPB) was used in 62 patients with a corresponding CPB time of 124.8 ± 68.4 min. In those patients who underwent CPB, cardioplegic arrest was performed in 53.2% of patients with a mean cross-clamp time of 74.9 ± 41.9 min. Overall 30-day, 1-year and 5-year survival rates were 81.4, 66.5 and 51.6%, respectively, without significant differences according to the underlying aetiology. Multivariate analysis revealed patients with reduced left ventricular ejection fraction (LVEF) [P = 0.01, odds ratio (OR) 3.6] and preoperative right ventricular dilatation (P = 0.04, OR 3.5) to be at significant risk of early mortality. Long-term mortality was independently predicted by the presence of coronary artery disease (CAD) [P < 0.001, hazard ratio (HR) 6.44], chronic obstructive pulmonary disease (P = 0.001, HR 4.21) and preoperative renal insufficiency (P = 0.012, HR 1.8). Concomitant tricuspid valve repair (TVR) appeared to provide protective effect on the long-term survival (P = 0.07). CONCLUSIONS Surgery for CP is associated with a significant risk based on the poor preoperative patient status. Whenever justified, partial over radical pericardiectomy should be preferred and TVR should be indicated liberally. Reduced LVEF and right ventricular dilatation were independent predictors for early mortality, whereas CAD, chronic obstructive pulmonary disease and renal insufficiency were risk factors for late mortality. Thus, an optimal timing for surgery on CP remains crucial to avoid secondary morbidity with an even worse natural prognosis.

Gingerol Inhibits Serum-Induced Vascular Smooth Muscle Cell Proliferation and Injury-Induced Neointimal Hyperplasia by Suppressing p38 MAPK Activation. J Cardiovasc Pharmacol Ther 2015; 21:187-200. [DOI: 10.1177/1074248415598003] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2014] [Accepted: 06/08/2015] [Indexed: 01/07/2023]
Abstract
Purpose: Gingerol inhibits growth of cancerous cells; however, its role in vascular smooth muscle cell (VSMC) proliferation is not known. The present study investigated the effect of gingerol on VSMC proliferation in cell culture and during neointima formation after balloon injury. Method and Results: Rat VSMCs or carotid arteries were harvested at 15 minutes, 30 minutes, 1, 6, 12, and 24 hours of fetal bovine serum (FBS; 10%) stimulation or balloon injury, respectively. Gingerol prevented FBS (10%)-induced proliferation of VSMCs in a dose-dependent manner (50 μmol/L-400 μmol/L). The FBS-induced proliferating cell nuclear antigen (PCNA) upregulation and p27Kip1 downregulation were also attenuated in gingerol (200 μmol/L) pretreated cells. Fetal bovine serum-induced p38 mitogen-activated protein kinase (MAPK) activation, PCNA upregulation, and p27Kip1 downregulation were abrogated in gingerol (200 μmol/L) and p38 MAPK inhibitor (SB203580, 10 μmol/L) pretreated cells. Balloon injury induced time-dependent p38 MAPK activation in the carotid artery. Pretreatment with gingerol (200 μmol/L) significantly attenuated injury-induced p38 MAPK activation, PCNA upregulation, and p27Kip1 downregulation. After 14 days of balloon injury, intimal thickening, neointimal proliferation, and endothelial dysfunction were significantly prevented in gingerol pretreated arteries. In isolated organ bath studies, gingerol (30 nmol/L-300 μmol/L) inhibited phenylephrine-induced contractions and induced dose-dependent relaxation of rat thoracic aortic rings in a partially endothelium-dependent manner. Conclusion: Gingerol prevented FBS-induced VSMC proliferation and balloon injury-induced neointima formation by regulating p38 MAPK. Vasodilator effect of gingerol observed in the thoracic aorta was partially endothelium dependent. Gingerol is thus proposed as an attractive agent for modulating VSMC proliferation, vascular reactivity, and progression of vascular proliferative diseases.

Abstract
This study aims to investigate the relationship between the levels of IL-18, IL-10, and MMP-9 and -137G/C polymorphism of interleukin 18 with the risk of in-stent restenosis (ISR). The study population consisted of 68 patients with ISR, 173 in non-ISR group, treated with drug-eluting stent and evaluated by coronary angiography post-procedure and at follow-up, and also 109 without angiographic evidence of coronary artery disease (CAD) which formed a reference control group (non-CAD group). The sequential plasma IL-18, IL-10, and MMP-9 levels were assessed at admission, 24 h, and 2 weeks after percutaneous coronary intervention. The -137G/C polymorphism of IL-18 was genotyped by the ligase detection reaction-polymerase chain reaction. Plasma IL-18 and MMP-9 increased significantly from admission, peaking after 24 h and fall after 2 weeks. Compared with the non-ISR group, the ISR group had higher levels of IL-18 and MMP-9, but IL-10 level was the opposite. The -137GG genotype of IL-18 was significantly higher than of the CG and CC genotypes. A significant higher frequency of -137G allele or GG genotype of IL-18 was observed in patients with ISR group compared with the non-ISR group. There is correlation between the changes of IL-18, IL-10, MMP-9, and ISR. IL-18 promoter -137G/C polymorphism influences IL-18 levels and the susceptibility to ISR, suggesting that IL-18-mediated pathways are causally involved in the process of ISR.

Abstract
Nutritional research has shifted recently from alleviating nutrient deficiencies to chronic disease prevention. We investigated the activity of indicaxanthin, a bioavailable phytochemical of the betalain class from the edible fruit of Opuntia ficus-indica (L. Miller) in a rat model of acute inflammation. Rat pleurisy was achieved by injection of 0.2 mL of λ-carrageenin in the pleural cavity, and rats were killed 4, 24, and 48 h later; exudates were collected to analyze inflammatory parameters, such as nitric oxide (NO), prostaglandin E(2) (PGE(2)), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α); cells recruited in pleura were analyzed for cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) expression, and nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) activation. Indicaxanthin (0.5, 1, or 2 μmol/kg), given orally before carrageenin, time- and dose-dependently, reduced the exudate volume (up to 70%) and the number of leukocytes recruited in the pleural cavity (up to 95%) at 24 h. Pretreatment with indicaxanthin at 2 μmol/kg inhibited the carrageenin-induced release of PGE(2) (91.4%), NO (67.7%), IL-1β (53.6%), and TNF-α (71.1%), and caused a decrease of IL-1β (34.5%), TNF-α (81.6%), iNOS (75.2%), and COX2 (87.7%) mRNA, as well as iNOS (71.9%) and COX-2 (65.9%) protein expression, in the recruited leukocytes. Indicaxanthin inhibited time- and dose- dependently the activation of NF-κB, a key transcription factor in the whole inflammatory cascade. A pharmacokinetic study with a single 2 μmol/kg oral administration showed a maximum 0.22 ± 0.02 μmol/L (n = 15) plasma concentration of indicaxanthin, with a half-life of 1.15 ± 0.11 h. When considering the high bioavailability of indicaxanthin in humans, our findings suggest that this dietary pigment has the potential to improve health and prevent inflammation-based disorders.

Abstract
Aging has been associated with pathological vascular remodeling and increased neointimal hyperplasia. The understanding of how aging exacerbates this process is fundamental to prevent cardiovascular complications in the elderly. This study proposes a mechanism by which aging sustains leukocyte adhesion, vascular inflammation, and increased neointimal thickness after injury. The effect of aging on vascular remodeling was assessed in the rat balloon injury model using microarray analysis, immunohistochemistry, and LINCOplex assays. The injured arteries in aging rats developed thicker neointimas than those in younger animals, and this significantly correlated with a higher number of tissue macrophages and increased vascular IL-18. Indeed, IL-18 was 23-fold more abundant in the injured vasculature of aged animals compared with young rats, while circulating levels were similar in both groups of animals. The depletion of macrophages in aged rats with clodronate liposomes ameliorated vascular accumulation of IL-18 and significantly decreased neointimal formation. IL-18 was found to inhibit apoptosis of vascular smooth muscle cells (VSMC) and macrophages, thus favoring both the formation and inflammation of the neointima. In addition, injured arteries of aged rats accumulated 18-fold more fibrinogen-γ than those of young animals. Incubation of rat peritoneal macrophages with immobilized IL-18 increased leukocyte adhesion to fibrinogen and suggested a proinflammatory positive feedback loop among macrophages, VSMC, and the deposition of fibrinogen during neointimal hyperplasia. In conclusion, our data reveal that concentration changes in vascular cytokine and fibrinogen following injury in aging rats contribute to local inflammation and postinjury neointima formation.

Abstract
Bindarit, a selective inhibitor of monocyte chemotactic proteins (MCPs) synthesis, reduces neointimal formation in animal models of vascular injury and recently has been shown to inhibit in-stent late loss in a placebo-controlled phase II clinical trial. However, the mechanisms underlying the efficacy of bindarit in controlling neointimal formation/restenosis have not been fully elucidated. Therefore, we investigated the effect of bindarit on human coronary smooth muscle cells activation, drawing attention to the phenotypic modulation process, focusing on contractile proteins expression as well as proliferation and migration. The expression of contractile proteins was evaluated by western blot analysis on cultured human coronary smooth muscle cells stimulated with TNF-α (30 ng/mL) or fetal bovine serum (5%). Bindarit (100-300 µM) reduced the embryonic form of smooth muscle myosin heavy chain while increased smooth muscle α-actin and calponin in both TNF-α- and fetal bovine serum-stimulated cells. These effects were associated with the inhibition of human coronary smooth muscle cell proliferation/migration and both MCP-1 and MCP-3 production. The effect of bindarit on smooth muscle cells phenotypic switching was confirmed in vivo in the rat balloon angioplasty model. Bindarit (200 mg/Kg/day) significantly reduced the expression of the embryonic form of smooth muscle myosin heavy chain, and increased smooth muscle α-actin and calponin in the rat carodid arteries subjected to endothelial denudation. Our results demonstrate that bindarit induces the differentiated state of human coronary smooth muscle cells, suggesting a novel underlying mechanisms by which this drug inhibits neointimal formation.

Abstract
The redox-sensitive transcription factors NF-κB and activator protein-1 (AP-1) are critical mediators of ANG II signaling. The promitogenic and promigratory factor interleukin (IL)-18 is an NF-κB- and AP-1-responsive gene. Therefore, we investigated whether ANG II-mediated smooth muscle cell (SMC) migration and proliferation involve IL-18. ANG II induced rat carotid artery SMC migration and proliferation and IL-18 and metalloproteinase (MMP)-9 expression via ANG II type 1 (AT(1)) receptor. ANG II-induced superoxide generation, NF-κB and AP-1 activation, and IL-18 and MMP-9 induction were all markedly attenuated by losartan, diphenyleneiodonium chloride (DPI), and Nox1 knockdown. Similar to ANG II, addition of IL-18 also induced superoxide generation, activated NF-κB and AP-1, and stimulated SMC migration and proliferation, in part via Nox1, and both ANG II and IL-18 induced NOX1 transcription in an AP-1-dependent manner. AT(1) physically associates with Nox1 in SMC, and ANG II enhanced this binding. Interestingly, exogenous IL-18 neither induced AT(1) binding to Nox1 nor enhanced the ANG II-induced increase in AT(1)/Nox1 binding. Importantly, IL-18 knockdown, or pretreatment with IL-18 neutralizing antibodies, or IL-18 binding protein, all attenuated the migratory and mitogenic effects of ANG II. Continuous infusion of ANG II for 7 days induced carotid artery hyperplasia in rats via AT(1) and was associated with increased AT(1)/Nox1 binding (despite lower AT(1) levels); increased DPI-inhibitable superoxide production; increased phospho-IKKβ, JNK, p65, and c-Jun; and induction of IL-18 and MMP-9 in endothelium-denuded carotid arteries. These results indicate that IL-18 amplifies the ANG II-induced, redox-dependent inflammatory cascades by activating similar promitogenic and promigratory signal transduction pathways. The ANG II/Nox1/IL-18 pathway may be critical in hyperplastic vascular diseases, including atherosclerosis and restenosis.

Abstract
OBJECTIVES We hypothesize that minimally invasive valve surgery in patients with chronic obstructive pulmonary disease (COPD) is superior to the conventional median sternotomy approach. METHODS We retrospectively reviewed 2846 consecutive surgery performed at our institution between January 2005 and September 2010, and identified 165 patients with COPD who underwent isolated valve surgery. In-hospital mortality, composite complication rates, intensive care unit and total hospital length of stay of those who had undergone a minimally invasive approach were compared with a cohort that underwent a standard median sternotomy approach. RESULTS Of the 165 patients, 100 underwent a minimally invasive approach and 65 had a median sternotomy. Baseline characteristics did not differ between the two groups. The mean age was 71 ± 11 years for the minimally invasive group and 68 ± 12 years for the median sternotomy group, (P = 0.31). In-hospital mortality was 1 (1%) in the minimally invasive group and 3 (5%) in the median sternotomy group, P = 0.14. Composite postoperative complications were significantly reduced in the minimally invasive group (30 versus 54%, P = 0.002). The median intensive care unit length of stay was 47 h (IQR 40-70) versus 73 h (IQR 51-112), P < 0.001, and the median postoperative length of stay was 6 days (IQR 5-9) versus 9 days (IQR 7-13), P < 0.001, for the minimally invasive and the median sternotomy groups, respectively. CONCLUSIONS Minimally invasive valve surgery in patients with COPD is associated with excellent short-term results, and thus should be considered an option in these patients.

Abstract
Status epilepticus increases brain-blood barrier (BBB) permeability leading to vasogenic edema. This BBB disruption is usually confined within relatively limited cerebral regions including the piriform cortex (PC), and leads to epileptogenesis and contributes to progression of epilepsy. Although cytokines are at least partly responsible for changes in BBB permeability, the role of interleukin-18 (IL-18) in vasogenic edema is not yet explored in detail. In the present study, we investigated the role of IL-18 in SE-induced vasogenic edema formation. Following SE, IL-18/interferon-γ (IFN-γ) system was up-regulated in astrocytes and microglia/macrophages. Recombinant rat (rr) IL-18 infusion decreased vasogenic edema formation, while anti-rat IL-18 infusion increased it. In contrast, rrIFN-γ, and anti-rat IFN-γ infusion showed reverse effects on vasogenic edema formation. rrIL-18 or anti-rat IFN-γ IgG infusion elevated dystrophin expression accompanied by the reduction in vasogenic edema. However, rr-IFN-γ or anti-rat IL-18 IgG infusion significantly decreased dystrophin immunoreactivity within the PC following SE. These findings indicate that IL-18-mediated up-regulation of dystrophin expression may play either a direct or indirect role in maintenance of BBB function following SE. Therefore, our findings suggest that IL-18 may have protective effect on SE-induced BBB disruption in IFN-γ independent mechanism.

Abstract
AIMS IκBNS regulates a subset of Toll-like receptor (TLR)-dependent genes including interleukin-6 (IL-6) by inhibiting nuclear factor-κB (NF-κB). IL-6 is an inflammatory biomarker for cardiovascular diseases. The aim of this study was to determine whether IκBNS changes arterial inflammation and intimal hyperplasia after vascular injury. METHODS AND RESULTS We investigated neointimal formation in IκBNS-deficient (IκBNS(-/-); C57BL/6 background) and wild-type (IκBNS(+/+)) mice 2 weeks after cuff injury. The mean intimal area and the intima/media ratio of IκBNS(-/-) mice increased 89% (8066 ± 1141 vs. 4267 ± 1095 μm(2); P = 0.027) and 100% (0.72 ± 0.13 vs. 0.36 ± 0.09; P = 0.032) compared with IκBNS(+/+) mice. We observed significant up-regulation of TLR4 in injured arteries of IκBNS(-/-) mice. NF-κB activity in the intima of IκBNS(-/-) mice was 5.1-fold higher (P = 0.008) compared with IκBNS(+/+) mice at 7 days post-injury. IL-6 mRNA levels in injured arteries of IκBNS(-/-) mice were 1.8-fold higher (P = 0.002) compared with those of IκBNS(+/+) mice at 3 days post-injury. Vascular smooth muscle cells from IκBNS(-/-) mice showed a significant increase in cell migration compared with those from IκBNS(+/+) mice after IL-6 stimulation in the scratch-wound healing assay. Furthermore, anti-mouse IL-6 receptor antibody (MR16-1) significantly reduced intimal hyperplasia compared with control IgG injection in IκBNS(-/-) mice. These findings suggest that IL-6 participates in the development of neointimal hyperplasia after vascular injury in IκBNS(-/-) mice. CONCLUSION IκBNS down-regulates TLR4 expression, NF-κB activity, and IL-6 production after vascular injury. IκBNS might suppress intimal hyperplasia caused by vascular inflammation such as atherosclerosis, and restenosis after angioplasty.

Abstract
We demonstrate for the first time that the pro-inflammatory cytokine interleukin (IL)-18 stimulates rapid and significant proliferation of SMC derived from human saphenous vein (VSMC), but not coronary artery. IL-18 also stimulates VSMC growth. Further investigations revealed that IL-18-induced VSMC proliferation was Wnt inducible secreted protein-1 (WISP1) dependent. In addition to inducing its own expression via phosphatidylinositol 3-kinase/Akt-dependent IKK/NF-κB activation, IL-18 stimulated glycogen synthase kinase 3β phosphorylation and degradation, β-catenin nuclear translocation and stabilization, T-cell factor-lymphoid enhancer binding factor (TCF-LEF) activation, and WISP1 induction. Moreover, WISP1 induced its own expression, and that of survivin and multiple matrix metalloproteinases via β-catenin/TCF-LEF interaction. WISP1 also activated AP-1, but not NF-κB, and induced matrix metalloproteinase (MMP)9 transcription in part via AP-1. Interestingly, WISP1 failed to regulate tissue inhibitors of matrix metalloproteinases (TIMP) expression. These novel findings indicate that IL-18 induces a series of signaling events that result in WISP1-mediated VSMC proliferation, survival and MMP induction that are key components of vein graft stenosis and this may be amplified by IL-18 and WISP1 autoregulation and cross-regulation.

Abstract
Fibroblasts are the primary cell type responsible for synthesis and remodeling of the extracellular matrix in the heart. A number of factors including growth factors, hormones and mechanical forces have been identified that modulate the production of extracellular matrix by cardiac fibroblasts. Inflammatory mediators including pro-inflammatory cytokines and chemokines also impact fibrosis of the heart. Recent studies have illustrated that interleukin-18 promotes a pro-fibrotic response in cardiac fibroblasts; however the effects of this cytokine on other aspects of fibroblast function have not been examined. While fibroblasts have long been known for their role in production and remodeling of the extracellular matrix, other functions of these cells are only now beginning to be appreciated. We hypothesize that exposure to interleukin-18 will stimulate other aspects of fibroblast behavior important in myocardial remodeling including proliferation, migration and collagen reorganization. Fibroblasts were isolated from adult male rat hearts and bioassays performed to determine the effects of interleukin-18 on fibroblast function. Treatment of fibroblasts with interleukin-18 (1-100ng/ml) resulted in increased production of extracellular matrix components and remodeling or contraction of three-dimensional collagen scaffolds by these cells. Furthermore, exposure to interleukin-18 stimulated fibroblast migration and proliferation. Treatment of heart fibroblasts with interleukin-18 resulted in the rapid activation of the c-Jun N-terminal kinase (JNK) and phosphoinositide 3-kinase (PI3-kinase) pathways. Studies with pharmacological inhibitors illustrated that activation of these pathways is critical to interleukin-18 mediated alterations in fibroblast function. These studies illustrate that interleukin-18 plays a role in modulation of cardiac fibroblast function and may be an important component of the inflammation-fibrosis cascade during pathological myocardial remodeling.

Cardiovasc Res 2009; 84:485-93. [PMID: 19592568 PMCID: PMC2777949 DOI: 10.1093/cvr/cvp238] [Citation(s) in RCA: 42] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2008] [Revised: 06/30/2009] [Accepted: 07/08/2009] [Indexed: 12/12/2022] Open
Abstract
AIMS Bindarit is an original compound with peculiar anti-inflammatory activity due to a selective inhibition of a subfamily of inflammatory chemokines, including the monocyte chemotactic proteins MCP-1/CCL2, MCP-3/CCL7, and MCP-2/CCL8. In this study, we investigated the effect of bindarit on neointima formation using two animal models of arterial injury: rat carotid artery balloon angioplasty and wire-induced carotid injury in apolipoprotein E-deficient (apoE(-/-)) mice. METHODS AND RESULTS Treatment of rats with bindarit (200 mg/kg/day) significantly reduced balloon injury-induced neointima formation by 39% at day 14 without affecting re-endothelialization and reduced the number of medial and neointimal proliferating cells at day 7 by 54 and 30%, respectively. These effects were associated with a significant reduction of MCP-1 levels both in sera and in injured carotid arteries of rats treated with bindarit. In addition, in vitro data showed that bindarit (10-300 microM) reduced rat vascular smooth muscle cell (VSMC) proliferation, migration, and invasion, processes contributing to the injury-induced neointima formation in vivo. Similar results were observed in hypercholesterolaemic apoE(-/-) mice in which bindarit administration resulted in a 42% reduction of the number of proliferating cells at day 7 after carotid injury and in a 47% inhibition of neointima formation at day 28. Analysis of the cellular composition in neointimal lesions of apoE(-/-) mice treated with bindarit showed that the relative content of macrophages and the number of VSMCs were reduced by 66 and 30%, respectively, compared with the control group. CONCLUSION This study demonstrates that bindarit is effective in reducing neointima formation in both non-hyperlipidaemic and hyperlipidaemic animal models of vascular injury by a direct effect on VSMC proliferation and migration and by reducing neointimal macrophage content. All of these data were associated with the inhibition of MCP-1 production.

Abstract
Exercise training (EX) following percutaneous transluminal coronary angiography (PTCA) reduces progression to restenosis and increases event-free survival rates. Our aim was to determine whether EX inhibits lesion development and/or alters the extracellular matrix (ECM) composition of the neointima (NI) in a porcine PTCA model. Miniature Yucatan swine were assigned to cage confinement (SED) or EX for 20 wk. After 16 wk, all animals underwent a PTCA procedure of the left anterior descending artery (LAD) and left circumflex artery (LCX), with subsequent placement of an externalized jugular catheter. Animals recovered for 2 days and then resumed the previous protocol of SED or EX. Twelve days following PTCA, all animals received an intravenous bromodeoxyuridine (BrdU) injection to label proliferating cells. At 28 days following PTCA, the animals were euthanized, the LAD and LCX excised, and underwent standard histological processing for total collagen, type I collagen, fibronectin, BrdU, and Verhoeff-van Gieson stain. Our results demonstrate that EX significantly decreased lesion size and NI proliferation (-48%) in the LAD (P < 0.05) but not the LCX. Furthermore, EX attenuated type I collagen expression only in LAD, whereas total collagen was increased (5.9%) and fibronectin was decreased (-7.9%) in the NI of both vessels (P < 0.05). In conclusion, EX following PTCA may increase event-free survival rates following PTCA by decreasing lesion size and altering ECM composition.

Abstract
AIMS There is evidence to suggest that stromal interaction molecule 1 (STIM1) functions as a Ca2+ sensor on the endoplasmic reticulum, leading to transduction of signals to the plasma membrane and opening of store-operated Ca2+ channels (SOC). SOC have been detected in vascular smooth muscle cells (VSMCs) and are thought to have an essential role in the regulation of contraction and cell proliferation. We hypothesized that knockdown of STIM1 inhibits VSMC proliferation and suppresses neointimal hyperplasia. METHODS AND RESULTS We examined the effect of the knockdown of STIM1 using a rat balloon injury model and cultured rat aortic VSMCs. Interestingly, knockdown of rat STIM1 by adenovirus delivery of small interfering RNA (siRNA) significantly suppressed neointimal hyperplasia in a rat carotid artery balloon injury model at 14 days after injury. The re-expression of human STIM1 to smooth muscle reversed the effect of STIM1 knockdown on neointimal formation. Rat aortic VSMCs were used for the in vitro assays. Knockdown of endogenous STIM1 significantly inhibited proliferation and migration of VSMCs. Moreover, STIM1 knockdown induced cell-cycle arrest in G0/G1 and resulted in a marked decrease in SOC. Replenishment with recombinant human STIM1 reversed the effect of siRNA knockdown. These results suggest STIM1 has a critical role in neointimal formation in a rat model of vascular injury. CONCLUSION STIM1 may represent a novel therapeutic target in the prevention of restenosis after vascular interventions.

Abstract
Interleukin 18 (IL-18) is a pro-atherogenic cytokine associated with the occurrence of various cardiac complications. The IL-18 gene has a functional -137 G/C polymorphism (rs187238) in the promoter region. Using the ligase detection reaction-polymerase chain reaction, we genotyped a cohort of patients in Chinese Han population in Xiangfan region. Case patients of coronary artery disease and control patients were identified by coronary angiography. The plasma IL-18 concentrations were measured by ELISA. A significant increase of G allele or GG-genotype was observed in 241 case patients compared to 145 control individuals (frequency of G allele = 0.90 vs 0.83, p=0.004; frequency of GG-genotype = 0.81 vs 0.68, p = 0.005). In case patients, G allele carriers in multi-vessel disease patients had a higher occurrence rate when compared to single-vessel disease patients, but no significant difference was detected (frequency of G allele = 0.92 vs 0.88, p=0.107; frequency of GG-genotype = 0.84 vs 0.75, p = 0.089). IL-18 protein concentration of the -137GG genotype was much higher than concentration of the CG and CC genotype (case patients: 229.1+/-131.5 vs 122.7+/-73.6 pg/ml, P < 0.001; control patients: 65.9+/-31.6 vs 42.4+/-19.5 pg/ml, P < 0.001). To conclude, IL-18 promoter -137G/C polymorphism influences IL-18 levels and the occurrence of coronary artery disease, suggesting that IL-18 is causally involved in the development of atherosclerosis.

Abstract
BACKGROUND Inflammatory cytokines such as interleukin (IL)-1 beta and IL-18 play an important role in the development of atherosclerosis and restenosis. Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is an adaptor protein that regulates caspase-1-dependent IL-1 beta and IL-18 generation; however, the role of ASC in vascular injury remains undefined. Here, we investigated the contribution of ASC to neointimal formation after vascular injury in ASC-deficient (ASC(-/-)) mice. METHODS AND RESULTS Wire-mediated vascular injury was produced in the femoral artery of ASC(-/-) and wild-type mice. Immunohistochemical analysis revealed that ASC was markedly expressed at the site of vascular injury. Neointimal formation was significantly attenuated in ASC(-/-) mice after injury. IL-1 beta and IL-18 were expressed in the neointimal lesion in wild-type mice but showed decreased expression in the lesion of ASC(-/-) mice. To investigate the contribution of bone marrow-derived cells, we developed bone marrow-transplanted mice and found that neointimal formation was significantly decreased in wild-type mice in which bone marrow was replaced with ASC(-/-) bone marrow cells. Furthermore, in vitro experiments showed that the proliferation activity of ASC(-/-) vascular smooth muscle cells was not impaired. CONCLUSIONS These findings suggest that bone marrow-derived ASC is critical for neointimal formation after vascular injury and identify ASC as a novel therapeutic target for atherosclerosis and restenosis.

Abstract
BACKGROUND Stenosis at a vascular anastomotic site has been a significant clinical issue. We tested the hypothesis that rapamycin-eluting biodegradable poly L-lactic acid and epsilon-caprolactone copolymer (PLA-CL) film applied externally can inhibit neointimal hyperplasia in a canine vascular anastomosis model. METHODS Femoral artery graft interposition was performed in 25 beagles. Beagles were divided into five groups (five in each): graft interposition without PLA-CL film (control); with PLA-CL film only; and PLA-CL containing rapamycin 8 microg, 80 microg, and 800 microg. Orthotopic arterial graft interposition was performed on the left side and vein graft from the ipsilateral femoral vein was interposed on the right. Morphometric and immunochemical analyses were performed at four-week intervals. RESULTS In arterial graft models, the ratio of intimal area (intimal area divided by the entire vessel area) was significantly reduced in all the three rapamycin-eluting film groups compared with control (0.19, 0.07, 0.05, and 0.38 in 8 microg, 80 microg, 800 microg groups and control, respectively, p < 0.05). In vein graft models, the ratio of intimal area was significantly decreased only in the 800 microg rapamycin group compared with control (0.33 vs 0.54, p < 0.05). Inhibition of neointimal growth was associated with reduced cell proliferation, as evidenced by proliferating cell nuclear antigen immunostaining and diminished alpha-actin positive vascular smooth muscle cells. CONCLUSIONS Rapamycin-eluting biodegradable PLA-CL film applied externally can inhibit neointimal hyperplasia of arterial and vein grafts in a canine model. The inhibitory effect of rapamycin-eluting film against neointimal growth is more pronounced in the arterial graft than the vein graft.

Abstract
Interleukin 18 (IL-18) is suspected to play an important role in atherosclerosis and plaque vulnerability. We had previously shown that haplotypes combining two IL18 gene polymorphisms in complete linkage disequilibrium, C-105T (rs360717) in 5'-untranslated region (UTR) and A+183G (rs5744292) in 3'-UTR, were related to IL-18 circulating levels and cardiovascular outcome, the C(-105) G(+183) haplotype being associated with lower IL-18 levels and lower cardiovascular risk. This study was aimed at investigating the functional role of the two polymorphisms and their haplotypes on IL18 expression levels. Allelic imbalance experiments conducted in 24 and 20 subjects heterozygous for the C-105T and the A+183G polymorphisms did not detect any difference when subjects were considered as a whole (-0.009+/-0.044, P=0.85 and +0.114+/-0.082, P=0.18, respectively). However, when splitting individuals according to their haplo-genotype, the haplotype C(-105) G(+183) was associated with a lower expression level than C(-105) A(+183) (-0.287+/-0.076, P=0.005), but did not differ from T(-105) A(+183) (-0.138+/-0.083, P=0.13). The lower expression associated with C(-105) G(+183) was confirmed by real-time reverse transcription-PCR. Transfection of different haplotypic versions of the 3'-UTR did not show any difference in the expression of an upstream reporter gene. A 10-h study of the mRNA degradation kinetics by allelic imbalance with the A+183G polymorphism did not show any differential allelic degradation. In conclusion, the haplotype associated with lower IL-18 circulating concentrations and a lower cardiovascular risk was consistently associated with decreased IL18 expression levels, although the exact functional mechanisms remain to be elucidated.
