Abstract
Macrophage activation plays a central role in the development of atherosclerotic plaques. Interaction with oxidized low-density lipoprotein (oxLDL) leads to macrophage differentiation into foam cells and oxylipin production, contributing to plaque formation. 7-Ketocholesterol (7KC) is an oxidative byproduct of cholesterol found in oxLDL particles and is considered a factor contributing to plaque progression. During atherosclerotic lesion regression or stabilization, macrophages undergo a transformation from a pro-inflammatory phenotype to a reparative anti-inflammatory state. Interleukin-10 (IL-10) and PGE1 appear to be crucial in resolving both acute and chronic inflammatory processes. After coffee consumption, the gut microbiota processes non-absorbed chlorogenic acids producing various lower size phenolic acids. These colonic catabolites, including dihydroferulic acid (DHFA), may exert various local and systemic effects. We focused on DHFA's impact on inflammation and oxidative stress in THP-1 macrophages exposed to oxLDL, 7KC, and lipopolysaccharides (LPS). Our findings reveal that DHFA inhibits the release of several pro-inflammatory mediators induced by LPS in macrophages, such as CCL-2, CCL-3, CCL-5, TNF-α, IL-6, and IL-17. Furthermore, DHFA reduces IL-18 and IL-1β secretion in an inflammasome-like model. DHFA demonstrated additional benefits: it decreased oxLDL uptake and CD36 expression induced by oxLDL, regulated reactive oxygen species (ROS) and 8-isoprostane secretion (indicating oxidative stress modulation), and selectively increased IL-10 and PGE1 levels in the presence of inflammatory stimuli (LPS and 7KC). Finally, our study highlights the pivotal role of PGE1 in foam cell inhibition and inflammation regulation within activated macrophages. This study highlights DHFA's potential as an antioxidant and anti-inflammatory agent, particularly due to its ability to induce PGE1 and IL-10.

Brain Behav Immun 2023; 114:407-413. [PMID: 37704011 DOI: 10.1016/j.bbi.2023.09.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 09/05/2023] [Accepted: 09/09/2023] [Indexed: 09/15/2023] Open
Abstract
BACKGROUND Inflammatory activity during pregnancy and the postpartum period shifts systematically due to pregnancy progression, delivery, and postpartum recovery. Factors that deregulate inflammatory activity increase the risk for adverse pregnancy outcomes and slower postpartum recovery. The IL-6:IL-10 or TNF-α:IL-10 ratio is potentially one way to capture peripheral inflammatory regulation; higher values indicate that anti-inflammatory IL-10 is less effective at regulating pro-inflammatory TNF-α or IL-6, skewing towards maladaptive pro-inflammatory profiles. Associations between partner relationship quality and IL-6:IL-10 or TNF-α:IL-10 trajectories during pregnancy and the postpartum period have not been assessed. The purpose of this study was to test whether partner relationship quality (support, conflict) is associated with attenuated IL-6, IL-10, TNF-α, TNF-α:IL-10 or IL-6:IL-10 trajectories from the third trimester to the postpartum period. METHODS A sample of 162 women from the Healthy Babies Before Birth study reported on partner relationship quality (support and conflict) using the Social Support Effectiveness Questionnaire during the third trimester. Plasma samples were collected in the third trimester and at 1-, 6- and 12-months postpartum, and assayed for TNF-α, IL-6 and IL-10. Associations between both indicators of relationship quality (support and conflict) and TNF-α, IL-6, IL-10, IL-6:IL-10, TNF-α:IL-10 trajectories were tested using multi-level modelling, controlling for sociodemographic, pregnancy and health variables. RESULTS Partner support interacted with time to predict IL-6:IL-10 trajectories, linear: b = -0.176, SE = 0.067, p =.010, quadratic: b = 0.012, SE = 0.005, p =.009. Lower partner support was associated with steeper increases in IL-6:IL-10 from the third trimester to 6 months postpartum, followed by steeper decreases in IL-6:IL-10 from 6 months postpartum to a year after birth. Partner conflict was not associated with IL-6:IL-10 levels at study entry, b = 0.233, SE = 0.219, p =.290, or over time, p's > 0.782. Neither indicator of partner relationship quality was associated with TNF-α, IL-6, IL-10, or TNF-α:IL-10 trajectories, p's > 0.205. CONCLUSION Lower partner support may be associated with reduced moderation of IL-6 by IL-10 between pregnancy and a year postpartum, with possible consequences for maternal health and well-being.

Abstract
Evidence suggests that inflammation plays an important role in atherosclerosis and the consequent clinical presentation, including stable coronary artery disease (CAD) and acute coronary syndromes (ACS). The most essential elements are cytokines, proteins with hormone-like properties that are produced by the immune cells, endothelial cells, platelets, fibroblasts, and some stromal cells. Interleukins (IL-1β and IL-6), chemokines, interferon-γ (IFN-γ), and tumor necrosis factor-alpha (TNF-α) are the cytokines commonly associated with endothelial dysfunction, vascular inflammation, and atherosclerosis. These molecules can be targeted by commonly used therapeutic substances or selective molecules that exert targeted anti-inflammatory actions. The most significant anti-inflammatory therapies are aspirin, statins, colchicine, IL-1β inhibitors, and IL-6 inhibitors, along with novel therapies such as TNF-α inhibitors and IL-1 receptor antagonists. Aspirin and statins are well-established therapies for atherosclerosis and CAD and their pleiotropic and anti-inflammatory actions contribute to their efficacy and favorable profile. Colchicine may also be considered in high-risk patients if recurrent ACS episodes occur when on optimal medical therapy according to the most recent guidelines. Recent randomized studies have also shown that therapies specifically targeting inflammatory interleukins and inflammation can reduce the risk for cardiovascular events, but these therapies are yet to be fully implemented in clinical practice. Preclinical research is also intense, targeting various inflammatory mediators that are believed to be implicated in CAD, namely repeated transfers of the soluble mutant of IFN-γ receptors, NLRP3 inflammasome inhibitors, IL-10 delivery by nanocarriers, chemokine modulatory treatments, and reacting oxygen species (ROS) targeting nanoparticles. Such approaches, although intriguing and promising, ought to be tested in clinical settings before safe conclusions can be drawn. Although the link between inflammation and atherosclerosis is significant, further studies are needed in order to elucidate this association and improve outcomes in patients with CAD.

Abstract
SCOPE While cocoa flavanol (CF) consumption improves cardiovascular risk biomarkers, molecular mechanisms underlying their protective effects are not understood. OBJECTIVE To investigate nutri(epi)genomic effects of CF and identify regulatory networks potential mediating vascular health benefits. METHODS AND RESULTS Twenty healthy middle-aged men consume CF (bi-daily 450 mg) or control drinks for 1 month. Microarray analysis identifies 2235 differentially expressed genes (DEG) involved in processes regulating immune response, cell adhesion, or cytoskeleton organization. Distinct patterns of DEG correlate with CF-related changes in endothelial function, arterial stiffness, and blood pressure. DEG profile negatively correlates with expression profiles of cardiovascular disease patients. CF modulated DNA methylation profile of genes implicates in cell adhesion, actin cytoskeleton organization, or cell signaling. In silico docking analyses indicate that CF metabolites have the potential of binding to cell signaling proteins and transcription factors. Incubation of plasma obtained after CF consumption decrease monocyte to endothelial adhesion and dose-dependently increase nitric oxide-dependent chemotaxis of circulating angiogenic cells further validating the biological functions of CF metabolites. CONCLUSION In healthy humans, CF consumption may mediate vascular protective effects by modulating gene expression and DNA methylation towards a cardiovascular protective effect, in agreement with clinical results, by preserving integrity of immunological-endothelial barrier functions.

Abstract
Ischemic stroke is a leading cause of disability and death. It imposes a heavy economic burden on individuals, families and society. The mortality rate of ischemic stroke has decreased with the help of thrombolytic drug therapy and intravascular intervention. However, the nerve damage caused by ischemia-reperfusion is long-lasting and followed by multiple organ dysfunction. In this process, the immune responses manifested by systemic inflammatory responses play an important role. It begins with neuroinflammation following ischemic stroke. The large number of inflammatory cells released after activation of immune cells in the lesion area, along with the deactivated neuroendocrine and autonomic nervous systems, link the center with the periphery. With the activation of systemic immunity and the emergence of immunosuppression, peripheral organs become the second “battlefield” of the immune response after ischemic stroke and gradually become dysfunctional and lead to an adverse prognosis. The purpose of this review was to describe the systemic immune responses after ischemic stroke. We hope to provide new ideas for future research and clinical treatments to improve patient outcomes and quality of life.

Abstract
ABSTRACT Atherosclerosis is the primary cause of many cardiovascular diseases, and an increasing number of studies have shown that berberine could delay plaque formation and development. Therefore, we aimed to evaluate its effects and explore its mechanisms in this meta-analysis. We searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang, and VIP databases for original preclinical studies to conduct meta-analysis. Twelve articles (16 studies; 312 ApoE -/- mice) were included, and all the studies scored 3-5 points according to SYRCLE's risk of bias tool. Berberine could significantly decrease plaque area and plaque macrophage content (plaque area, SMD = -2.02, 95% CI: -2.80 to -1.24, P = 0.000; plaque macrophage content, SMD = -4.28, 95% CI: -7.67 to -0.88, P = 0.013); lower the levels of TC, triglyceride, and low-density lipoprotein (TC, SMD = -1.47, 95% CI: -2.20 to -0.74, P = 0.000; triglyceride, SMD = -0.77, 95% CI: -1.21 to -0.33, P = 0.000; low-density lipoprotein, SMD = -0.61, 95% CI: -1.11 to -0.11, P = 0.000), and change the secretion of inflammatory cytokines (IL-1β, SMD = -2.29, 95% CI: -3.40 to -1.18, P = 0.000; interleukin-6, SMD = -1.48, 95% CI: -2.11 to -0.85, P = 0.008; tumor necrosis factor-α, SMD = -1.98, 95% CI: -3.01 to -0.94, P = 0.000; interleukin-10, SMD = 1.78, 95% CI: 0.76 to 2.80, P = 0.015), but there were no significant differences in high-density lipoprotein levels and plaque lipid content (high-density lipoprotein, SMD = 0.02, 95% CI: -0.35 to 0.40, P = 0.021; plaque lipid content, SMD = -6.85, 95% CI: -21.09 to 7.39, P = 0.007). The results were robust across a range of sensitivity analyses. Therefore, the results indicate that berberine is a promising drug for the treatment of atherosclerosis through regulating lipid metabolism, inflammation, and plaque composition. However, some potential mechanisms remain to be further elucidated.

Abstract
Resolution is an active and highly coordinated process that occurs in response to inflammation to limit tissue damage and promote repair. When the resolution program fails, inflammation persists. It is now understood that failed resolution is a major underlying cause of many chronic inflammatory diseases. Here, we will review the major failures of resolution in atherosclerosis, including the imbalance of proinflammatory to pro-resolving mediator production, impaired clearance of dead cells, and functional changes in immune cells that favor ongoing inflammation. In addition, we will briefly discuss new concepts that are emerging as possible regulators of resolution and highlight the translational significance for the field.

Abstract
Interleukin-10 (IL-10) is an important immunomodulatory cytokine, initially characterized as an anti-inflammatory agent released by immune cells during infectious and inflammatory processes. IL-10 exhibits biological functions that extend to the regulation of different intracellular signaling pathways directly associated with vascular function. This cytokine plays a vital role in vascular tone regulation through the change of important proteins involved in vasoconstriction and vasodilation. Numerous investigations covered here have shown that therapeutic strategies inducing IL-10 result in anti-inflammatory, anti-hypertrophic, antihyperplastic, anti-apoptotic and antihypertensive effects. This non-systematic review summarizes the modulating effects mediated by IL-10 in vascular tissue, particularly on vascular tone, and the intracellular pathway induced by this cytokine. We also highlight the advances in IL-10 manipulation as a therapeutic target in different cardiovascular pathophysiologies, including the physiological implications in animals and humans. Finally, the review illustrates current and potential future perspectives of the potential use of IL-10 in clinical trials, based on the clinical evidence.

Abstract
Blood-Brain Barrier (BBB) disruption is an important pathophysiological process of acute ischemic stroke (AIS), resulting in devastating malignant brain edema and hemorrhagic transformation. The rapid activation of immune cells plays a critical role in BBB disruption after ischemic stroke. Infiltrating blood-borne immune cells (neutrophils, monocytes, and T lymphocytes) increase BBB permeability, as they cause microvascular disorder and secrete inflammation-associated molecules. In contrast, they promote BBB repair and angiogenesis in the latter phase of ischemic stroke. The profound immunological effects of cerebral immune cells (microglia, astrocytes, and pericytes) on BBB disruption have been underestimated in ischemic stroke. Post-stroke microglia and astrocytes can adopt both an M1/A1 or M2/A2 phenotype, which influence BBB integrity differently. However, whether pericytes acquire microglia phenotype and exert immunological effects on the BBB remains controversial. Thus, better understanding the inflammatory mechanism underlying BBB disruption can lead to the identification of more promising biological targets to develop treatments that minimize the onset of life-threatening complications and to improve existing treatments in patients. However, early attempts to inhibit the infiltration of circulating immune cells into the brain by blocking adhesion molecules, that were successful in experimental stroke failed in clinical trials. Therefore, new immunoregulatory therapeutic strategies for acute ischemic stroke are desperately warranted. Herein, we highlight the role of circulating and cerebral immune cells in BBB disruption and the crosstalk between them following acute ischemic stroke. Using a robust theoretical background, we discuss potential and effective immunotherapeutic targets to regulate BBB permeability after acute ischemic stroke.

Abstract
Interleukin (IL)-10 cytokine family members, including IL-10, IL-19, IL-20, IL-22, IL-24, IL-26 and the distantly related IL-28A, IL-28B, and IL-29, play critical roles in the regulation of inflammation. The occurrence and progression of cardiovascular diseases closely correlate with the regulation of inflammation, which may provide novel strategies for the treatment of cardiovascular diseases. In recent years, studies have focused on the association between the IL-10 cytokine family and the physiological and pathological progression of cardiovascular diseases. The aim of this review is to summarize relevant studies and clarify whether the IL-10 cytokine family contributes to the regulation of cardiovascular diseases.

Abstract
Background Danhong injection (DHI), which is one of the most well-known Traditional Chinese Medicine (TCM) injections, widely used to treat unstable angina (UA). However, its underlying pharmacological mechanisms need to be further clarified. Methods In the present study, network pharmacology was adopted. Firstly, the relative compounds were obtained by a wide-scaled literatures-mining and potential targets of these compounds by target fishing were collected. Then, we built the UA target database by DisGeNET, DigSee, TTD, OMIM. Based on data, protein-protein interaction (PPI) analysis, GO and KEGG pathway enrichment analysis were performed and screen the hub targets by topology. Furthermore, evaluation of the binding potential of key targets and compounds through molecular docking. Results The results showed that 12 ingredients of DHI and 27 putative known therapeutic targets were picked out. By systematic analysis, identified 4 hub targets (TNF, TLR4, NFKB1 and SERPINE1) mainly involved in the complex treating effects associated with coagulation and hemostasis, cell membrane region, platelet alpha granule, NF-kappa B signaling pathway and TNF signaling pathway. Conclusion The results of this study preliminarily explained the potential targets and signaling pathways of DHI in the treatment of UA, which may help to laid a good foundation for experimental research and further clinical application.

Abstract
Cardiac surgery results in a multifactorial systemic inflammatory response with inflammatory cytokines, such as interleukin-10 and 6 (IL-10 and IL-6), shown to have potential in the prediction of adverse outcomes including readmission or mortality. This study sought to measure the association between IL-6 and IL-10 levels and 1-year hospital readmission or mortality following cardiac surgery. Plasma biomarkers IL-6 and IL-10 were measured in 1,047 patients discharged alive after isolated coronary artery bypass graft surgery from eight medical centers participating in the Northern New England Cardiovascular Disease Study Group between 2004 and 2007. Readmission status and mortality were ascertained using Medicare, state all-payer claims, and the National Death Index. We evaluated the association between preoperative and postoperative cytokines and 1-year readmission or mortality using Kaplan-Meier estimates and Cox's proportional hazards modeling, adjusting for covariates used in the Society of Thoracic Surgeons 30-day readmission model. The median follow-up time was 1 year. After adjustment, patients in the highest tertile of postoperative IL-6 values had a significantly increased risk of readmission or death within 1 year (HR: 1.38; 95% CI: 1.03-1.85), and an increased risk of death within 1 year of discharge (HR: 4.88; 95% CI: 1.26-18.85) compared with patients in the lowest tertile. However, postoperative IL-10 levels, although increasing through tertiles, were not found to be significantly associated independently with 1-year readmission or mortality (HR: 1.25; 95% CI: .93-1.69). Pro-inflammatory cytokine IL-6 and anti-inflammatory cytokine IL-10 may be postoperative markers of cardiac injury, and IL-6, specifically, shows promise in predicting readmission and mortality following cardiac surgery.

Abstract
Hepatitis C virus (HCV) infects 180 million people worldwide and over 4 million people in the United States. HCV infection is a major cause of chronic liver disease and is recognized as a risk factor for clinical cardiovascular disease (CVD). Many studies have shown increased prevalence of cardiac and inflammatory biomarkers in patients with chronic HCV infection (CHC), and though these markers may be used to risk stratify people for cardiac disease in the general population their role in the HCV population is unknown. Patients with CHC have elevated cardiac and inflammatory biomarkers compared to noninfected controls which may play a role in CVD risk stratification. We undertook a systematic review of inflammatory and cardiac biomarkers in people with HCV infection with a focus on the effect of CHC on serum levels of these markers and their utility as predictors of CVD in this population. Medline, EMBASE, and Cochrane databases were searched for relevant articles until June 2019. A total of 2430 results were reviewed with 115 studies included. Our review revealed that HCV infection significantly alters serum levels of markers of inflammation, endothelial function, and cardiac dysfunction prior to HCV treatment, and some of which may change in response to HCV therapy. Current risk stratification tools for development of CVD in the general population may not account for the increased inflammatory markers that appear to be elevated among HCV‐infected patients contributing to increased CVD risk.

Abstract
Decreased anabolism because of alterations in the insulin-like growth factor 1 (IGF-1)/growth hormone (GH) axis and increased catabolism induced by proinflammatory cytokines like tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) have been reported to contribute to muscle wasting in chronic heart failure (CHF). However, it is unclear whether exercise training could modulate anabolic and catabolic markers in CHF patients. The purpose of this study was to investigate the effects of exercise intervention on anabolic and catabolic markers for patients with CHF. Literatures were systematically searched in electronic databases and relevant references. Only published randomized controlled trials (RCTs) focusing on exercise training for CHF were eligible for inclusion. Outcome measurements included serum level and muscle biopsy of TNF-α, IL-6, GH, and IGF-I. Of the six included studies, four showed no significant difference between exercise group and control group in the serum levels of TNF-α, IL-6, GH, and IGF-I. However, two studies showed significant reduction in TNF-α and IL-6 and increase in IGF-I by local skeletal muscle biopsy. We conclude that the decreases in catabolic markers and increases in anabolic after exercise training were evident only by local skeletal muscle biopsy. More RCTs on dose-response relation of exercise programs are needed to further optimize anabolic and anti-inflammatory benefits of exercise training in patients with CHF.

Abstract
Uremia-related inflammation is prone to be a key factor to explain high cardiovascular morbidity in hemodialysis patients. Genetic susceptibility may be of importance, including IL-10, IL-6, and TNF. The aim was to analyze IL-10, IL-6, and TNF gene polymorphisms in a group of hemodialysis patients and to correlate the findings with cardiovascular morbidity. This study included 169 patients on regular hemodialysis at Zvezdara University Medical Center. Gene polymorphisms for IL-10, IL-6 and TNF were determined using PCR. These findings were correlated with the cardiovascular morbidity data from patient histories. Heterozygots for IL-10 gene showed significantly lower incidence of cardiovascular events (p = 0.05) and twice lower risk for development of myocardial infarction, but experienced twice higher risk for left ventricular hypertrophy. Regarding TNF gene polymorphism, patients with A allele had 1.5-fold higher risk for cerebrovascular accident and cardiovascular events and 2-fold higher risk for hypertension and peripheral vascular disease. Patients with G allele of IL-6 gene experienced 1.5-fold higher risks for cerebrovascular accident. We need studies with larger number of patients for definitive conclusion about the influence of gene polymorphisms on cardiovascular morbidity in hemodialysis patients and its importance in everyday clinical practice.

Abstract
The influence of optimal medical treatment (OMT) with or without additional percutaneous transluminal angioplasty (PTA) on vascular inflammation in peripheral arterial occlusive disease (PAD) patients was investigated. Patients with intermittent claudication (IC) and angiographically verified PAD were randomized to OMT (n = 28) or OMT + PTA (n = 28) and followed for 12 months. Ankle—brachial index (ABI), treadmill walking distances (WD), visual analogue scale (VAS), and blood sampling for the determination of selected soluble biomarkers were undertaken at baseline and after 3 and 12 months. After both 3 and 12 months, ABI, WD and VAS were highly significantly improved in favour of OMT + PTA (p < 0.05 for all). Significant improvements were recorded in both groups in serum lipids (p < 0.01 for all), except for triglycerides, and in the inflammatory markers P-selectin, interleukin-6, interleukin-10, monocyte chemoattractant protein-1 and fibrinogen (p < 0.05 for all). There were, however, no differences in the changes from baseline between the groups in any variable. Intervention with OMT alone or in combination with PTA did not differ with regard to the effects on serum lipids and markers of inflammation in our population of PAD patients. The combined treatment was, however, better for the treadmill walking distance.

Abstract
Post-ischemic inflammation plays an important role in the progression of ischemia/reperfusion injuries. Prothymosin-α (ProT) can protect cells from necrotic death following ischemia; however, its immunostimulatory actions may counteract the neuroprotective effect. We proposed that ProTΔNLS, synthesized by deleting its nuclear localizing signal (NLS) at the C-terminal of ProT, can attenuate the immunostimulatory activity and has more salient neuroprotective effect. In this study, we examined the therapeutic effects of ProT and ProTΔNLS in a transient middle cerebral artery occlusion (tMCAO) model of rats. Rats that had sustained 90 min of tMCAO were treated with GST-vehicle, ProT, or ProTΔNLS. Therapeutic outcomes were evaluated by infarction volume assay and behavioral assessment. Changes to inflammatory mediators, including tumor necrosis factor α (TNF-α), interleukin-10 (IL-10), and myeloperoxidase (MPO) were evaluated by enzyme-linked immunosorbent assay. Activated matrix metalloproteinases 2 (MMP-2) and 9 (MMP-9) levels were evaluated by gelatin zymography. Microglial activation was identified by double-immunostaining for Iba-1 and CD68. Our results showed that while both ProT and ProTΔNLS reduce infarction volume and improve functional outcome, ProTΔNLS provides the best therapeutic outcome. ProT increases TNF-α but decreases IL-10 secretion after ischemic injury, reflecting its pro-inflammatory activity. ProTΔNLS suppresses expression of TNF-α, MPO, and activity of MMPs in ischemic brain tissue. It also suppresses activation of microglia in penumbral cortex. These data demonstrate the immunesuppressive activities of ProTΔNLS. In conclusion, ProT has pro-inflammatory effect that may counteract its neuroprotective effect. Deletion of NLS from ProT may attenuate post-ischemic inflammation and enhance the neuroprotective effects of ProT.

Abstract
Background: There is a strong relationship between physical inactivity and low-grade inflammation and its adverse health outcomes, particularly cardiovascular disease. The level of anti-inflammatory and pro-inflammatory cytokines may be changed by exercise. Objectives: The aim of the present study was to determine the response of certain inflammatory biomarkers to exercise with differences in maximal oxygen consumption (VO2max). These biomarkers were IL-1β, TNF-α, hs-CRP, IL-6, sICAM-1, IL-10, and ratios of TNF-α/IL-10 and IL-6/IL-in circulating peripheral blood (PB). Materials and Methods: In a semi-experimental study, twenty male students who performed regular football exercise at least three days a week, for two years, were selected by easy sampling at Shahid Chamran university of Iran. Subjects were then randomly assigned to two groups: the protocol of the first group was 30 minutes of running at a speed of 65% of VO2max, and the second group performed six periodic repetitions with three minutes at a speed of 85% of VO2max with a 90-second rest between the repetitions. Blood samples were taken at baseline, immediately after the exercise and at rest. Cytokine levels were quantified by the Sandwich enzyme-linked immunosorbent assay (ELISA) method. Results: The first protocol resulted in a decrease of serum IL-1β to 3.77 ± 0.28 pg/mL at rest, from 4.33 ± 0.28 at baseline and 4.32 ± 0.34 immediately after exercise (P = 0.008 and P = 0.013, respectively). There was also a decrease in the level of sICAM-1 to 260.11±15.64 ng/mL at rest, from 329.58 ± 20.82 at baseline and 302.7 ± 20.49 post exercise (P = 0.013 and P = 0.038, respectively). On the other hand, IL-6 and ratio of IL-6/IL-10 increased to 6.55±0.84 pg/mL and 2.12 ± 0.37 immediately after exercise from baseline (2.73 ± 0.58 and 1.16 ± 0.33) and rest (2.49 ± 0.45 and 0.95 ± 0.19) in the second protocol (P = 0.001 and P = 0.001, respectively for IL-6, and P = 0.047 and P = 0.024, respectively for IL-6/IL-10). Conclusions: The data of the present study demonstrated that a single bout of exercise with higher-intensity induces a transient increase in some proinflammatory markers, and lower-intensity can reduce these biomarkers.

We have studied the relationship between clinical and biochemical parameters and C-peptide and anti-inflammatory IL-10, as well as selected markers of inflammation and endothelial dysfunction such as: CCL2, CRP, sICAM-1, sVCAM-1 and E-selectin in obese women with various degree of glucose metabolism disturbance. MATERIAL AND METHODS The studied group consisted of 61 obese women, and 20 normal weight, healthy volunteers. Obese patients were spited in subgroups based on the degree of glucose metabolism disorder. Serum samples were analyzed using ELISA kits. RESULTS Increased concentrations of sICAM-1, sVCAM-1, E-selectin, CCL2 and CRP were found in all obese groups compared to the normal weight subjects. In patients with Type 2 diabetes mellitus (T2DM) parameters characterizing the degree of obesity significantly positively correlated with levels of CRP and CCL2. Significant relationships were found between levels of glucose and sICAM-1and also E-selectin and HOMA-IR. C-peptide levels are positively associated with CCL2, E-selectin, triglycerides levels, and inversely with IL-10 levels in newly diagnosed T2DM group (p<0.05). Concentrations of IL-10 correlated negatively with E-selectin, CCL2, C-peptide levels, and HOMA-IR in T2DM group (p<0.05). CONCLUSION Disturbed lipid and carbohydrate metabolism are manifested by enhanced inflammation and endothelial dysfunction in patients with simply obesity. These disturbances are associates with an increase of adhesion molecules. The results suggest the probable active participation of higher concentrations of C-peptide in the intensification of inflammatory and atherogenic processes in obese patients with type 2 diabetes. In patients with obesity and type 2 diabetes, altered serum concentrations of Il-10 seems to be dependent on the degree of insulin resistance and proinflammatory status.

Abstract
Monocytes and dendritic cells (DC) produce tumour necrosis factor (TNF)α during inflammatory processes, but secrete interleukin (IL)-10 simultaneously in order to balance the pro-inflammation. In the present study, we investigated the expression of TNFα and IL-10 by monocytes and DC in patients with a poor cardiovascular prognosis after 10 years. Peripheral blood monocytes were isolated from 30 patients with coronary artery disease (CAD) with stable angina pectoris (SAP), or with an acute coronary syndrome (ACS). Monocytes were differentiated over 7 days to DC. Intracellular accumulation of TNFα and IL-10 in monocytes and DC was analysed by flow cytometry and correlated with the heart function, total and cardiovascular (CV) mortality, as well as with cardiovascular event rate over 10 years. We observed a decreased left ventricular function (LV-EF) for both SAP and ACS patients (p<0.01), as well as a reduced IL-10/TNFα ratio for monocytes (p=0.01) and DC (p<0.01) for both patient groups in comparison to age-matched control group. Only the IL-10/TNFα ratio for monocytes correlated with LV-EF (r=0.4302; p<0.01). Patients with a low LV-EF as well as patients with a low IL-10/TNFα ratio showed an increased cardiovascular mortality over 10 years (both p<0.05). The IL-10/TNFα ratio is decreased in patients with low ejection fraction and poor prognosis. The reduced heart function correlates with an increased proinflammatory state (low monocytic IL-10/TNFα ratio) in patients with CAD. This observed imbalance of IL-10 and TNFα in monocytes might explain pathophysiological processes in atherosclerosis and heart failure.

Abstract
Atherosclerosis is primarily a disorder of lipid metabolism, but there is also a prominent chronic inflammatory component that drives the atherosclerotic lesion progression in the artery wall. During hyperlipidaemic conditions, there is a rapid influx of circulating monocytes into the atherosclerosis-prone areas of the arterial intima. These infiltrated monocytes differentiate into macrophages and take up the atherogenic lipoproteins in the intima of the vessel wall that have been modified within the lesion environment. Interleukin (IL)-10 is a prototypic anti-inflammatory cytokine made primarily by the macrophages and Th2 subtype T lymphocytes. In terms of atherosclerosis its major roles include inhibition of macrophage activation as well as inhibition of matrix metalloproteinase, pro-inflammatory cytokines and cyclooxygenase-2 expression in lipid-loaded and activated macrophage foam cells. Recent discoveries suggest another important role of IL-10 in atherosclerosis: its ability to alter lipid metabolism in macrophages. The current review will highlight the present knowledge on multiple ways in which IL-10 mediates atherosclerosis. As macrophages play a critical role in all stages of atherosclerosis, the review will concentrate on how IL-10 regulates the activities of macrophages that are especially important in the development of atherosclerosis.

Abstract
AIM To compare inflammatory response accompanying acute coronary syndrome (ACS) with that following coronary plaque rupture caused by coronary angioplasty (PCI). METHODS Twenty-seven consecutive subjects with either ACS or treated with PCI in the subacute phase of ACS underwent serial evaluation of circulating interleukin (IL)-2, IL-8, IL-10, interferon (IFN)-γ and tumor-necrosis-factor (TNF)-α levels. Blood samples were drawn immediately before angioplasty (T0) in the PCI group or at admission in the ACS group, 12 h (T1) and 24 h later (T2). RESULTS Differences between cytokine levels were substantially not statistically significant when comparing PCI, non-ST-elevation-ACS, and ST-elevation-ACS groups, especially 24 h after plaque rupture (T2, Type-II error 85-94%). CONCLUSIONS Inflammatory activation during the first 24 h of ACS or after PCI is comparable, regardless of myocardial damage in terms of troponin levels. Coronary plaque rupture may be presumed as being the main responsible for increased circulating cytokine levels in this early phase.

Abstract
Interleukin (IL)-10 is a prototypical anti-inflammatory cytokine that has been shown to attenuate atherosclerosis development. In addition to its anti-inflammatory properties, the anti-atherogenic effect of IL-10 has recently also been suggested to reflect a complex effect of IL-10 on lipid metabolism in macrophages. In the present study we examined the effects of IL-10 on cholesterol efflux mechanism in lipid-loaded THP-1 macrophages. Our main findings were: (i) IL-10 significantly enhanced cholesterol efflux induced by fetal-calf serum, high-density lipoprotein (HDL)2 and apolipoprotein A-1. (ii) The IL-10-mediated effects on cholesterol efflux were accompanied by an increased IL-10-mediated expression of the ATP-binding cassette transporters ABCA1 and ABCG1, that was further enhanced when the cells were co-activated with the liver X receptor (LXR)α agonist (22R)-hydroxycholesterol. (iii) The effect of LXRα activation on the IL-10-mediated effects on the ATP-binding cassette transporters seems to include enhancing effects on the IL-10 receptor 1 (IL10R1) expression and interaction with STAT-3 signaling. (iv) These enhancing effects on ABCA1 and ABCG1 was not seen when the cells were stimulated with the IL-10 family members IL-22 and IL-24. This study suggests that the anti-atherogenic properties of IL-10 may include enhancing effects on cholesterol efflux mechanism that involves cross-talk with LXRα activation.

Abstract
BACKGROUND Androgen deficiency (AD) is associated with increased risk of atherosclerosis, cardiovascular, and peripheral arterial disease. Although the biochemical and molecular mechanisms underlying this risk remain unclear, higher testosterone (TST) levels correlate to significant immunoprotective molecular and cellular responses. Our group has previously demonstrated that female sex hormones influence vascular pathogenesis via inflammatory-modulated matrix metalloproteinase (MMP) regulation. Here we investigated the role of AD and androgen replacement therapy in the modulation of these hormonally responsive pathways that could be playing a role in the development of vascular pathogenesis. METHODS Aged orchiectomized male rats underwent TST supplementation per controlled release pellet implantation (0-150 mg). Young and aged intact groups served as controls. Serum was collected at 0-4 wk and analyzed by enzyme-linked immunosorbent assays, qualitative cytokine screening, and quantitative multiplex analyses. Human aortic smooth muscle cells were treated with 4,5α-dihydrotestosterone (DHT; 0-3000 nM) before or after interleukin 1β (IL-1β; 5 ng/mL) stimulation. Quantitative polymerase chain reaction and in-gel zymography was used to assay the effect on MMP expression and activity. RESULTS Subphysiological, physiological, and supraphysiological levels of TST were achieved with 0.5, 2.5, and 35 mg TST pellet implants in vivo, respectively. Inflammatory arrays indicated that interleukin cytokines, specifically IL-2, IL-6, IL-10, IL-12, and IL-13, were elevated at subphysiological level of TST, whereas TST supplementation decreased interleukins. Supraphysiological TST resulted in a significant increase in MMP-9 and tissue inhibitor of metalloproteinase-1 (TIMP-1) in vivo. Pretreatment with IL-1β slightly increased membrane type 1-MMP (MT1-MMP) and MMP-2 expression at low to mid-level DHT exposure in vitro, although these trends were not statistically significant. CONCLUSIONS Here we demonstrate AD is a proinflammatory modulator and indicate that MMP-independent mechanisms may play a role downstream of AD-induced inflammatory signaling in dysfunctional vascular remodeling. Future in vivo studies will examine AD and TST supplementation in acute inflammatory response to vascular injury and in MMP-modulated vascular disease.

Abstract
BACKGROUND Patients with diabetes mellitus (DM) have an increased risk for periprocedural complications and adverse cardiac events after percutaneous coronary intervention. We addressed the potential for coronary microvascular obstruction and restenosis in patients with and without DM undergoing stenting for saphenous vein bypass graft (SVG) stenosis under protection with a distal occlusion/aspiration device. METHODS SVG plaque volume and composition were analyzed using intravascular ultrasound before stent implantation. Percent diameter stenosis was determined from quantitative coronary angiography before, immediately after and 6 months after stent implantation. Coronary aspirate was retrieved during stent implantation and divided into particulate debris and plasma. Total calcium, several vasoconstrictors, and tumor necrosis factor (TNF)α in particulate debris and coronary aspirate plasma were determined. RESULTS Patients with and without DM had similar plaque volume, but larger necrotic core and greater particulate debris release in patients with than without DM (20.3±2.7 vs. 12.7±2.6% and 143.9±19.3 vs. 75.1±10.4 mg, P<0.05). The TNFα concentration in particulate debris and coronary aspirate plasma was higher in patients with than without DM (15.9±6.6 vs. 5.1±2.4 pmol/mg and 2.2±0.7 vs. 1.1±0.2 pmol/L, P<0.05), whereas total calcium and vasoconstrictors were not different. Patients with DM had a greater percent diameter stenosis 6 months after stent implantation than those without DM (22.17±5.22 vs. 6.34±1.11%, P<0.05). The increase in TNFα immediately after stent implantation correlated with restenosis 6 months later (r=0.69, P<0.05). CONCLUSION In diabetics, particulate debris and coronary aspirate plasma contained more TNFα, which might reflect the activity of the underlying atherosclerotic process.

Abstract
OBJECTIVE Familial hypercholesterolaemia (FH) is associated with increased risk of premature atherosclerosis. Inflammation is a key event in atherogenesis, and we have previously reported an inflammatory imbalance between tumour necrosis factor (TNF)α and interleukin-10 in children with FH. Based on the potential role of TNF-related molecules in inflammation, we investigated the regulation of other members of the TNF superfamily (TNFSF)/TNF receptor superfamily (TNFRSF) in children and young adults with FH and matched healthy controls. METHODS Expression of TNFSF/TNFRSF genes in peripheral blood mononuclear cells (PBMCs) was quantified in children and young adults with FH prior to (n = 42) and after statin treatment (n = 10) and in controls (n = 25) by quantitative real-time polymerase chain reaction. RESULTS First we found that, compared with controls, the mRNA levels of OX40L, BAFFR and TRAILR1 were significantly higher, whereas TRAIL and TRAILR3 were significantly lower in children and young adults with FH. Secondly, levels of oxidized low-density lipoprotein (oxLDL) were significantly raised in the FH group, and correlated with the expression of OX40L, BAFFR and TRAILR1. Thirdly, oxLDL increased mRNA levels of BAFFR, TRAILR1 and TRAILR4 in PBMCs ex vivo from individuals with FH. Fourthly, OX40, acting through OX40L, enhanced the oxLDL-induced expression of matrix metalloproteinase-9 in THP-1 monocytes in vitro. Finally, after statin treatment in children with FH (n = 10), mRNA levels of OX40L and TRAILR1 decreased, whereas levels BAFF, TRAIL and TRAILR3 increased. CONCLUSION Our findings suggest the involvement of some TNFSF/TNFRSF members and oxLDL in the early stages of atherogenesis; this may potentially contribute to the accelerated rate of atherosclerosis observed in individuals with FH.

Abstract
Heart failure (HF) is a clinical syndrome manifested by signs and symptoms of low cardiac output, pulmonary, and/or systemic congestion. Immunologically, HF is defined as a state of immune activation and persistent inflammation, especially the circulatory levels of inflammatory cytokines have been found to increase. Traditional drugs used in HF have expressed immunomodulatory and/or anticytokine activities that may participate in their therapeutic efficacy in the disease. The angiotensin-converting enzyme inhibitors like captopril and enalapril as well as the angiotensin II receptor antagonist losartan indicated in HF exerted reducing effects on the inflammatory cytokines such as tumor necrosis factor-alpha and interleukin-6 at experimental and clinical levels. Aldosterone antagonists like spironolactone when administered concomitantly with losartan can attenuate angiotensin II-enhanced cytokine production in HF. Carvedilol beta-adrenergic blockers showed a wider spectrum of anti-inflammatory/anticytokine activity that proved to be associated with improvement of cardiac function and ejection fraction in patients with HF. The poor prognosis in HF despite the long experience with its treatment necessitated thinking about new drugs to be added to the traditional ones. Methotrexate and statins are examples of these drugs, especially because they exert immunologic effects. A low dose of methotrexate has been considered as a hopeful adjunct therapy in chronic HF, but large long-term clinical trials are required. Statins showed conflicting results, although they might be useful early after acute ischemic events associated with left ventricular dysfunction or failure, especially in younger patients with less advanced HF.

Abstract
OBJECTIVE The goal of this study was to examine the association of the antiinflammatory interleukin-10 (IL-10) with risk of cardiovascular disease (CVD). METHODS AND RESULTS In the PROSPER (PROspective Study of Pravastatin in the Elderly at Risk) cohort, we related baseline concentrations of circulating IL-10 to risk of CVD events in a nested case (n=819)-control (n=1618) study of 3.2 years of follow-up. Circulating IL-10 showed few strong associations with classical risk factors but was positively correlated with IL-6 and C-reactive protein. IL-10 was positively associated with risk of CVD events (odds ratio [OR] 1.17, 95% CI 1.05 to 1.31 per unit increase in log IL-10) after adjusting for classical risk factors and C-reactive protein. Furthermore, IL-10 was associated more strongly with CVD risk among those with no previous history of CVD (OR 1.42, 95% CI 1.18 to 1.70), compared with those with previous CVD (OR 1.04, 95% CI 0.90 to 1.19; P=0.018). Overall, IL-10 showed a modest ability to add discrimination to classical risk factors (C-statistic +0.005, P=0.002). CONCLUSIONS Baseline circulating levels of the antiinflammatory IL-10 are positively associated with risk of CVD among the elderly without prior CVD events, although the association is less evident in those with a history of CVD. Additional epidemiological and mechanistic studies investigating the role of IL-10 in CVD are warranted.

Abstract
INTRODUCTION Erectile dysfunction (ED) is highly prevalent among type 2 diabetes mellitus patients (T2DM). Although a link among systemic inflammation, endothelial dysfunction, and ED is described in clinical situations mainly related with coronary heart disease (CHD) risk, evidences of this link in T2DM patients are rather limited. AIMS To evaluate the association between endothelial dysfunction and balance of pro-/anti-inflammatory mediators with ED presence and severity in T2DM. METHODS We conducted a cross-sectional study of 190 T2DM patients without symptomatic CHD, 150 out of them with ED and 40 without ED. Serum levels of E-selectin, intercellular adhesion molecule-1, tumor necrosis factor-α (TNF-α), and interleukin (IL)-10 were measured using specific enzyme-linked immunosorbent assays (ELISAs). ED presence and severity were tested by the five-item version of the International Index of Erectile Function questionnaire. MAIN OUTCOME MEASURES Differences in circulating levels of endothelial dysfunction (ICAM-1, E-selectin) and inflammatory/anti-inflammatory (TNF-α, IL-10, TNF-α : IL-10 ratio) markers between T2DM patients with and without ED, and assessment of biomarkers ED predictive value while adjusting for other known ED risk factors. RESULTS Patients with ED were older and had longer duration of diabetes than patients without ED. E-selectin serum levels were significantly increased, while IL-10 were lower in patients with ED; because TNF-α levels tend to be higher, TNF-α : IL-10 ratio was more elevated in ED patients. No significant differences of ICAM-1 levels were observed between study groups. Endothelial activation markers and TNF-α, as well as diabetes duration, were negatively correlated with erectile function. On multivariate analysis including age, duration of diabetes, insulin treatment, hypertension, insulin resistance, fair-to-poor glycemic control, and metabolic syndrome, increments in E-selectin levels and TNF-α : IL-10 ratio predicted independently ED presence, while IL-10 increases were associated with lower risk of ED in T2DM patients. CONCLUSIONS ED in T2DM patients without symptomatic CHD is associated with systemic endothelial dysfunction and a predominant, imbalanced low-grade inflammatory response.

Abstract
The aim of this study is to investigate the release of some inflammatory cytokines (Cks) during the very early phase (first 24 h) of acute coronary syndrome (ACS). Twenty-six consecutive subjects admitted to coronary care unit with ACS underwent serial blood sampling in order to evaluate concentrations of interleukin (IL)-2, IL-10, IL-18, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ. Blood samples were taken within 6 h after onset of chest pain (T₀), at 12 h (T₁), and at 24 h (T₂). Patients were thus divided into four groups comparing pro-inflammatory Ck release (IL-2, TNF-α, and IFN-γ) and anti-inflammatory activity (IL-10). Clinical features, risk factors, incidence of adverse events, and coronary angiography findings were compared with Ck activation. Ck levels were significantly increased if compared with baseline. Subjects with marked inflammatory response showed a higher incidence of left anterior descending coronary disease (IL-2, p < 0.001; TNF-α and IFN-γ, p < 0.05) and more often incurred early complications (IL-2, p < 0.05; IFN-γ, p < 0.001). A correlation was detectable between IL-18 levels and myocardial enzyme release (creatine kinase, r = 0.47; lactate dehydrogenase, r = 0.54; troponin I, r = 0.58; p < 0.05). TNF-α levels were associated with a worse prognosis at follow-up (Log rank, p < 0.05). A Ck activation characterizes the early phase of ACS. Early inflammatory reaction seems to correlate with coronary disease and adverse events.

Abstract
Oxidative stress and inflammation are each implicated independently in the development and progression of heart failure. Their interaction, however, is also evident throughout the process from initial injury to cardiac remodeling and failure. In the failing heart, the linkage between excessive reactive oxygen species (ROS) and the cytokine elaboration is manifested in shared elements and cross-promotion within downstream signaling pathways. In spite of this, the failure of anticytokine immunotherapy and antioxidant therapy, which had previously shown promise, suggests that a more complete perspective of ROS-cytokine interaction is required. The present review focuses on two of the major cytokines that are demonstrably connected to oxidative stress--the pro-inflammatory tumor necrosis factor-alpha (TNF-alpha) and the anti-inflammatory interleukin-10 (IL-10)--and their interactions in cardiac remodeling and failure. It is proposed that an optimal balance between TNF-alpha and IL-10 may be of crucial importance in mitigating both inflammation and oxidative stress processes leading to heart failure.

Abstract
TNF-α is a proinflammatory cytokine and is an important mediator of maternal endothelial dysfunction leading to preeclampsia. In this study, we tested whether IL-10 protects against TNF-α-induced endothelial dysfunction in murine aorta. In in vitro experiments, aortic rings of C57BL/6 female mice were incubated in Dulbecco's modified Eagle's medium in the presence of either vehicle (distilled H(2)O), TNF-α (4 nmol/l), or recombinant mouse IL-10 (300 ng/ml) or in the presence of both TNF-α and IL-10 for 22 h at 37°C. In in vivo experiments C57BL6/IL-10 knockout female mice were treated with saline or TNF-α (220 ng·kg(-1)·day(-1)) for 14 days. Aortic rings were isolated from in vitro and in vivo experiments and mounted in a wire myograph (Danish Myotech) and stretched to a tension of 5 mN. Endothelium-dependent relaxation was assessed by constructing cumulative concentration-response curves to acetylcholine (ACh, 0.001-10 μmol/l) during phenylephrine (10 μmol/l)-induced contraction. As a result, overnight exposure of aortic rings to TNF-α resulted in significant blunted maximal relaxing responses (E(max)) to ACh compared with untreated rings (22 ± 4 vs. 82 ± 3%, respectively). IL-10 knockout mice treated with TNF-α showed significant impairment in ACh responses (E(max)) compared with C57BL/6 mice treated with TNF-α (51 ± 3 vs. 72 ± 3%, respectively). Western blot analysis showed that endothelial nitric oxide synthase (eNOS) expression was reduced by TNF-α in in vitro and in vivo experiments, whereas IL-10 restored the eNOS expression. In conclusion, the anti-inflammatory cytokine IL-10 prevents impairment in endothelium-dependent vasorelaxation caused by TNF-α by protecting eNOS expression.

Abstract
Potential mechanisms and biomarkers of atherosclerosis related to cigarette smoking - a modifiable risk factor for that disease - are discussed in this article. These include smoking-associated inflammatory markers, such as leukocytes, high-sensitivity C-reactive protein, serum amyloid A, ICAM-1 and IL-6. Other reviewed markers are indicative for smoking-related impairment of arterial endothelial function (transcapillary leakage of albumin, inhibition of endogenous nitric oxide synthase activity and reduced endothelium-dependent vasodilation) or point to oxidative stress caused by various chemicals (cholesterol oxidation, autoantibodies to oxidized low-density lipoprotein, plasma levels of malondialdehyde and F(2)-isoprostanes and reduced antioxidant capacity). Smoking enhances platelet aggregability, increases blood viscosity and shifts the pro- and antithrombotic balance towards increased coagulability (e.g., fibrinogen, von Willebrand factor, ICAM-1 and P-selectin). Insulin resistance is higher in smokers compared with nonsmokers, and hemoglobin A1c is dose-dependently elevated, as is homocysteine. Smoke exposure may influence the kinetics of markers with different response to transient or chronic changes in cigarette smoking behavior.

Abstract
The aim of this study was to analyze (i) ratios between pro-inflammatory cytokines interleukin 6 (IL-6), interleukin 1 (IL-1), tumour necrosis factor alpha (TNF-alpha) and anti-inflammatory cytokine interleukin 10 (IL-10) in patients with acute myocardial infarction (AMI) and stable angina pectoris (ii) as well as correlation between IL-6 and IL-10 in AMI and (iii) correlation between IL-6 and lipoproteins in AMI.The total of 71 patients were enrolled in this study, 41 of them with AMI (study group) and 30 with stable angina pectoris (control group). The concentrations of cytokines and lipoproteins were measured from blood samples. Pro-inflammatory to anti-inflammatory cytokine ratios were calculated by dividing concentrations of pro-inflammatory cytokines with IL-10. In statistical analyses we used descriptive statistics, normality tests and analysis of correlation.IL-6: IL-10 ratio is significantly higher in AMI than in stable angina (P < 0,001), TNF-alpha: IL-10 is also higher in study group but the difference is not significant. We found positive linear correlation between IL-6 and IL-10 (r =0,43; p = 0,015) and negative linear correlation between IL-6 and high density lipoprotein HDL (r = -0,47; p= 0,008) in AMI.IL-6: IL-10 ratio is higher in AMI than in stable angina. There is linear correlation between IL-6 and IL-10 and IL-6 and HDL in AMI.

Abstract
BACKGROUND Cytokines are responsible for the modulation of immunological and inflammatory processes and play a significant role in the pathogenesis of coronary artery disease (CAD). Tumor necrosis factor (TNF)-alpha is the major pro-inflammatory cytokine while interleukin-10 (IL-10) is the major anti-inflammatory cytokine in patients with CAD. We determined the significance of the TNF/IL-10 ratio and C-reactive protein (CRP) in patients of acute myocardial infarction as a marker for CAD in the atherosclerosis-prone North Indian population. METHODS The study group comprised of 100 patients of acute myocardial infarction (AMI) and 100 age and sex matched healthy controls. Lipid profile, apolipoprotein-A (Apo-A), apolipoprotein-B (Apo-B) and CRP concentrations were estimated using commercially available kits in all patients and control subjects. TNF-alpha, lipoprotein (a) (Lp(a)) and IL-10 concentrations were assayed by using commercially available ELISA kits. RESULTS The TNF-alpha concentrations were significantly higher in patients with acute myocardial infarction (86.9+/-4.7 pg/ml), as compared to control subjects (7.1+/-0.67 g/ml). AMI patients also exhibited higher serum concentrations of IL-10 (5.74+/-0.82 pg/ml), in comparison to the controls (1.22+/-0.06 pg/ml). The ratio of TNF-alpha to IL-10 was significantly increased in cases (15.2+/-1.13), in comparison to healthy subjects (5.8+/-0.64). CONCLUSIONS These cytokines underline the role of the immune processes during unstable atherosclerosis and in the pathogenesis of coronary artery disease in the Indian context.

Abstract
Cytokines are responsible for the modulation of immunological and inflammatory processes and play a significant role in the pathogenesis of coronary artery disease. We estimated the levels of pro-/anti-inflammatory cytokines in South Indian patients with coronary artery disease. The study population comprised of groups 1-3: 100 patients each with acute myocardial infarction, unstable angina, and stable angina, respectively, and group 4 (100 healthy controls). Cytokine levels (interleukin-6, interleukin-8, interleukin-10, and tumor necrosis factor-alpha) were estimated by enzyme-linked immunosorbent assay (ELISA). Interleukin-6, interleukin-8, and tumor necrosis factor-alpha levels were significantly higher in patients from groups 1 and 2, than in group 3 and controls. Acute myocardial infarction patients exhibited higher serum levels of interleukin-10 compared with other groups and control subjects. Patients with unstable angina had significantly lower interleukin-10 concentrations than those with stable angina. The ratios of pro-/anti-inflammatory cytokines in all the study groups increased significantly when patients with unstable angina were compared to other groups. In patients with acute myocardial infarction, interleukin-10 and tumor necrosis factor-alpha levels showed significant correlation with established risk factors such as body mass index, blood pressure, and lipid levels. Acute myocardial infarction patients show elevation in proinflammatory and anti-inflammatory cytokines, while unstable angina is associated with low levels of serum interleukin-10. Higher levels of anti-inflammatory cytokine interleukin-10 may be needed to provide protection in unstable angina. These cytokines are markers of coronary artery disease and may be used for the identification of high-risk patients with unstable angina/acute myocardial infarction.

Abstract
Our understanding of the multiple in vivo functions of the proinflammatory cytokine, tumor necrosis factor (TNFalpha), is advancing at a rapid pace. In addition to its antitumor effects, overproduction of TNFalpha provokes tissue injury and organ failure. TNFalpha has also been shown to be cardiodepressant and responsible for various cardiovascular complications. It appears that still much needs to be learned for a full comprehension of the role of TNFalpha in heart biology. Another cytokine, interleukin-10 (IL-10), has been shown to have anti-inflammatory properties. It is suggested to counterbalance many adverse effects of TNFalpha. IL-10 suppresses the production of TNFalpha and many other proinflammatory cytokines. TNFalpha-induced oxidative stress is also known to be mitigated by IL-10. Moreover, improvement in cardiac function after treatment with various drugs is also shown to be associated with an increase in IL-10 content. Based on the data reviewed in here, it is suggested that an optimal balance between IL-10 and TNFalpha may be a new therapeutic strategy for a healthier heart.

Abstract
AIM The aim of this study is to investigate the T helper (Th)2-dependent release of interleukin(IL)-4 and IL-13 in patients with unstable angina treated with coronary angioplasty (PCI). METHODS This study involved 48 consecutive patients with unstable angina who underwent PCI. Blood samples were taken before and 48 h after PCI to evaluate serum IL-4 and IL-13 levels. Coronary atherosclerosis was assessed in terms of the severity of the treated lesions and the presence of multivessel disease, and compared with IL release. RESULTS Before and after PCI, serum IL-4 levels were, respectively, 53.1+/-110.7 and 35.1+/-16.9 pg/ml (P not significant), and serum IL-13 levels 6.7+/-3.7 and 6.0+/-2.9 pg/ml (P<0.05). A correlation was present between the severity of the treated coronary lesions and serum IL-13 levels (r 0.36; P<0.05). The patients with multivessel coronary artery disease had a higher periprocedure ratio of IL-4 than those with single-vessel coronary artery disease (1.46+/-0.76 vs. 0.89+/-0.34, P<0.001). CONCLUSION A significant decrease was observed in Th2-dependent IL concentrations after PCI; increased Th2-dependent IL levels before PCI seem to correlate with the severity of coronary atherosclerosis.

Abstract
PRIMARY OBJECTIVE Granulocyte-colony stimulating factor (G-CSF) is used for the mobilization of bone marrow and endothelial progenitor cells, though G-CSF-induced inflammation may cause endothelial dysfunction. We examined the effects of G-CSF on endothelium, C-reactive protein (CRP), tumour necrosis factor-alpha (TNF-alpha) and anti-inflammatory cytokines namely interleukin 10 (IL-10). RESEARCH DESIGN We studied 60 women with breast cancer, who were randomized to either subcutaneous G-CSF (5 microg/kg), o.d. for 5 days after adjuvant chemotherapy (n = 40) or placebo (n = 20). EXPERIMENTAL INTERVENTIONS We measured flow-mediated dilatation (FMD%) of the brachial artery by ultrasonography, CRP, TNF-alpha, IL-10 and the ratio TNF-alpha/ IL-10 blood levels before, 2-h and 5-days after the G-CSF or placebo treatment. MAIN OUTCOMES AND RESULTS There was a greater increase of FMD, IL-10 and reduction of TNF-alpha/ IL-10, 2 h and 5 days after the G-CSF treatment compared to placebo. Although, CRP and TNF-alpha were higher, TNF-alpha/IL-10 was lower at the end of G-CSF treatment compared to placebo. Improvement of FMD was related to changes of IL-10 and TNF-alpha/IL-10. CONCLUSIONS Treatment with G-CSF improves endothelial function in vivo, possibly by shifting the balance between the pro- and anti-inflammatory cytokines.

Abstract
Initiation and progression of coronary atherosclerosis has been associated with inflammation and cytokines balance. The objective of this study is to understand the role of cytokines in the pathophysiology and management of coronary artery disease. Coronary artery disease has been revisited with revision of the pertinent published articles in the Medline, Scopus, and EBSCO Host research from 1987 to 2007. The 2 groups of cytokines (proinflammatory and anti-inflammatory) have been detected in human atherosclerotic plaques. The balance between the 2 groups may reflect the intensity of occult plaque inflammation and the vulnerability to rupture. Multiple studies have determined that a diverse set of proinflammatory biomarkers can furnish prognostic information beyond the traditional risk factors. Inflammatory responses after coronary revascularization are known to play key role in vascular lesion formation early in atherosclerosis and restenosis. Clinical utilization of cytokines remains promising yet incompletely explored and need more studies.

Abstract
BACKGROUND CD14 receptor is a mediator of the inflammatory response to bacterial products. A functional polymorphism in the promoter of the CD14 gene (CD14 C-260T) was associated with coronary heart disease and atherosclerosis albeit with conflicting data. METHODS To better clarify the role of CD14 in atherosclerosis, we typed CD14 C-260T polymorphism in old Italian (Central of Italy) atherosclerotic patients with carotid stenosis related to lipid assessment, inflammation (soluble CD14, IL-6 serum levels) and IL-6, TNF-alpha, IL-10, Metallothioneins (MT) gene expressions in carotid plaques. RESULTS There was an increased frequency of TT homozygotes in patients when compared to controls [26% vs. 13.5%, odds ratio=2.25 (95% C.I., 1.23-4.09, p=0.0082) (Fisher's Exact test)]. Subjects with TT genotype showed a significant increase of soluble CD14 and enhanced MT2A, IL-6, TNF-alpha and decreased IL-10 gene expressions within the carotid plaques. On the basis of lipid assessment, hypercholesterolemic -260TT CD14 patients displayed lower HDL cholesterol and higher triglyceride than did CT and CC carriers. Using Pearson's correlation, a high MT2A expression was associated with high IL-6, TNF-alpha, sCD14 and thereby with severe chronic inflammation. CONCLUSIONS These data provide insight into the pathogenetic role of the CD14 C-260T polymorphism in atherosclerosis as -260TT genotype may favour increased inflammation in atheroma promoting possible worsening atherosclerosis, at least in Central of Italy elderly population. Further studies are in progress in cohorts from different European geographic area (Zincage project).
