Abstract
BACKGROUND Despite advances in cardiovascular medicine, coronary artery disease (CAD) remains a leading cause of mortality. Among the pathophysiological features of this condition, platelet-leukocyte aggregates (PLAs) require further attention, either as diagnostic/prognostic disease markers or as potential interventional targets. OBJECTIVES In this study, we characterized PLAs in patients with CAD. Primarily, we investigated the association of PLA levels with CAD diagnosis. In addition, the basal levels of platelet activation and degranulation were assessed in patients with CAD and controls, and their correlation with PLA levels was analyzed. Finally, the effect of antiplatelet treatments on circulating PLA numbers, basal platelet activation, and degranulation was studied in patients with CAD. METHODS Participants were recruited at the Department of Cardiology of the University Heart and Vascular Centre Hamburg Eppendorf. Among patients admitted with severe chest pain, the diagnosis of CAD was made angiographically, and patients without CAD were used as controls. PLAs, platelet activation, and platelet degranulation were assessed by flow cytometry. RESULTS Circulating PLAs and basal platelet degranulation levels were significantly higher in patients with CAD than in controls. Surprisingly, there was no significant correlation between PLA levels and platelet degranulation (or any other measured parameter). In addition, patients with CAD on antiplatelet therapy did not display lower PLA or platelet degranulation levels compared with those in controls. CONCLUSION Overall, these data suggest a mechanism of PLA formation that is independent of platelet activation or degranulation and highlights the inefficiency of current antiplatelet treatments for the prevention of basal platelet degranulation and PLA formation.

Abstract
AIM To evaluate the lipid-lowering and antiplatelet combined strategies on the expression of the receptors CCR2, CCR5, and CX3CR1 and the percentage of CCR2, CCR5, and CX3CR1 cells in monocyte subtypes after acute myocardial infarction. METHODS Prospective, randomized, open-label study, with blinded analyses of endpoints (PROBE, ClinicalTrials.gov Identifier: NCT02428374, registration date: April 28, 2015). Participants were treated with rosuvastatin 20 mg or simvastatin 40 mg plus ezetimibe 10 mg, as well as ticagrelor 90 mg or clopidogrel 75 mg. The chemokine receptors CCR2, CCR5, and CX3CR1 were analyzed by real-time polymerase chain reaction as well as the percentages of CCR2, CCR5, and CX3CR1 cells in the monocyte subtypes (classical, intermediate, and non-classical), which were quantified by flow cytometry, at baseline, and after 1 and 6 months of treatment. RESULTS After comparisons between the three visits, regardless of the treatment arm, there was an increase in CCR2 expression after treatment, as well as an increase in intermediate monocytes CCR2+ and a reduction in non-classical monocytes CCR2+ at the end of treatment. There was also a lower expression of CCR5 after treatment and an increase in classical and non-classical monocytes CCR5+. Concerning CX3CR1, there were no differences in the expression after treatment; however, there were reductions in the percentage of intermediate and non-classical monocytes CX3CR1+ at the end of treatment. CONCLUSIONS The results suggest the persistence of the inflammatory phenotype, known as trained immunity, even with the highly-effective lipid-lowering and antiplatelet therapies.

Abstract
Platelets have a great ability to modulate immune responses. Monocyte-platelet aggregates (MPAs) are associated with the pathogenesis of cardiac disease. Notably, a low preoperative platelet count often indicates poor postoperative recovery following acute aortic dissection (AAD). The functions of platelets and MPAs in AAD, however, remain poorly understood. We found that, despite decreased platelet counts, platelets were also activated in AAD patients, with significant alterations in immune-modulating mediators. Of interest, monocytes in AAD patients had a suppressed immune status, which was correlated with poor outcomes following surgery. Interestingly, platelets preferentially aggregated with monocytes, and the levels of MPAs were related to recovery after surgical repair in AAD patients. Platelets restored suppressed monocyte functions in AAD patients by forming aggregates and partly by secreting matrix metalloproteinase-9 (MMP-9). Thus, the results point to a previously unknown mechanism for platelets involving monocyte reprogramming, which may improve postoperative outcomes following complex cardiovascular surgery.

Abstract
BACKGROUND Chronic kidney disease (CKD) is usually considered an immune inflammatory disease. Interaction between platelets and monocytes is associated with immune inflammation. Cross-talk between platelets and monocytes is reflected by formation monocyte-platelet aggregates (MPAs). This study aims to test MPAs and MPAs with the different monocyte subsets to evaluate their association with disease severity in CKD. METHODS Forty-four hospitalized patients with CKD and twenty healthy volunteers were enrolled. The proportion of MPAs and MPAs with the different monocyte subsets were tested by flow cytometry. RESULTS The proportion of circulating MPAs in all patients with CKD were significantly higher than those of healthy controls (p<0.001). A higher proportion of MPAs with classical monocytes (CM) was found in CKD4-5 patients (p=0.007), while another higher proportion of MPAs with non-classical monocytes (NCM) was found CKD2-3 patients (p<0.001). The proportion of MPAs with intermediate monocytes (IM) in CKD 4-5 group was significantly higher in comparison to CKD2-3 group and healthy controls (p<0.001). Circulating MPAs were found to be correlated with serum creatinine (r=0.538, p<0.001) and eGFR (r=-0.864, p<0.001). The AUC for MPAs with IM was 0.942 (95% CI 0.890-0.994, p<0.001). CONCLUSIONS Study results highlight the interplay between platelets and inflammatory monocytes in CKD. There are alterations in circulating MPAs and MPAs with the different monocyte subsets in CKD patients compared to controls which change with CKD severity. The MPAs may have an important role in the development of CKD or as a predictive marker for monitoring disease severity.

Abstract
Chemokine receptors are fundamental in many processes related to cardiovascular diseases, such as monocyte migration to vessel walls, cell adhesion, and angiogenesis, among others. Even though many experimental studies have shown the utility of blocking these receptors or their ligands in the treatment of atherosclerosis, the findings in clinical research are still poor. Thus, in the current review we aimed to describe some promising results concerning the blockade of chemokine receptors as therapeutic targets in the treatment of cardiovascular diseases and also to discuss some challenges that need to be overcome before using these strategies in clinical practice.

Abstract
AIMS P-selectin is a key surface adhesion molecule for the interaction of platelets with leukocytes. We have shown previously that the N-terminal domain of Staphylococcus aureus extracellular fibrinogen-binding protein (Efb) binds to P-selectin and interferes with platelet-leukocyte aggregate formation. Here, we aimed to identify the minimal Efb motif required for binding platelets and to characterize its ability to interfering with the formation of platelet-leukocyte aggregates. METHODS AND RESULTS Using a library of synthetic peptides, we mapped the platelet-binding site to a continuous 20 amino acid stretch. The peptide Efb68-87 was able to bind to resting and, to a greater extent, thrombin-stimulated platelets in the absence of fibrinogen. Dot blots, pull-down assays and P-selectin glycoprotein ligand-1 (PSGL-1) competitive binding experiments identified P-selectin as the cellular docking site mediating Efb68-87 platelet binding. Accordingly, Efb68-87 did not bind to other blood cells and captured platelets from human whole blood under low shear stress conditions. Efb68-87 did not affect platelet activation as tested by aggregometry, flow cytometry and immunoblotting, but inhibited the formation of platelet-leukocyte aggregates (PLAs). Efb68-87 also interfered with the platelet-dependent stimulation of neutrophil extracellular traps (NETs) formation in vitro. CONCLUSIONS We have identified Efb68-87 as a novel selective platelet-binding peptide. Efb68-87 binds directly to P-selectin and inhibits interactions of platelets with leukocytes that lead to PLA and NET formation. As PLAs and NETs play a key role in thromboinflammation, Efb68-87 is an exciting candidate for the development of novel selective inhibitors of the proinflammatory activity of platelets.

Abstract
Extracellular vesicles (EVs) are nanosized membrane-bound structures released by cells that are able to transfer nucleic acids, protein cargos, and metabolites to specific recipient cells, allowing cell-to-cell communications in an endocrine and paracrine manner. Endothelial, leukocyte, and platelet-derived EVs have emerged both as biomarkers and key effectors in the development and progression of different stages of vascular damage, from earliest alteration of endothelial function, to advanced atherosclerotic lesions and cardiovascular calcification. Under pathological conditions, circulating EVs promote endothelial dysfunction by impairing vasorelaxation and instigate vascular inflammation by increasing levels of adhesion molecules, reactive oxygen species, and proinflammatory cytokines. Platelets, endothelial cells, macrophages, and foam cells secrete EVs that regulate macrophage polarization and contribute to atherosclerotic plaque progression. Finally, under pathological stimuli, smooth muscle cells and macrophages secrete EVs that aggregate between collagen fibers and serve as nucleation sites for ectopic mineralization in the vessel wall, leading to formation of micro- and macrocalcification. In this review, we summarize the emerging evidence of the pathological role of EVs in vascular damage, highlighting the major findings from the most recent studies and discussing future perspectives in this research field.

Abstract
Simple Summary Cardiovascular diseases are the most common cause of death worldwide. Hence, novel biomarkers are urgently needed to improve diagnosis and treatment. Platelet–leucocyte aggregates are conglomerates of platelets and leucocytes and are widely investigated as biomarkers in cardiovascular diseases. Platelet–leucocytes aggregates are present in health, but increase in patients with cardiovascular risk factors and acute or stable coronary syndromes, making them a potential diagnostic marker. Moreover, platelet–leucocyte aggregates predict outcomes after surgery or percutaneous treatment and could be used to monitor antiplatelet therapy. Emerging data about the participation of platelet–leucocyte aggregates in cardiovascular diseases pathogenesis make them an attractive target for novel therapies. Furthermore, simple detection with conventional flow cytometry provides accurate and reproducible results, although requires specific sample handling. The main task for the future is to determine the standardized protocol to measure blood concentrations of platelet–leucocyte aggregates and subsequently establish their normal range in health and disease. Abstract Platelet–leucocyte aggregates (PLA) are a formation of leucocytes and platelets bound by specific receptors. They arise in the condition of sheer stress, thrombosis, immune reaction, vessel injury, and the activation of leukocytes or platelets. PLA participate in cardiovascular diseases (CVD). Increased levels of PLA were revealed in acute and chronic coronary syndromes, carotid stenosis cardiovascular risk factors. Due to accessible, available, replicable, quick, and low-cost quantifying using flow cytometry, PLA constitute an ideal biomarker for clinical practice. PLA are promising in early diagnosing and estimating prognosis in patients with acute or chronic coronary syndromes treated by percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). PLA were also a reliable marker of platelet activity for monitoring antiplatelet therapy. PLA consist also targets potential therapies in CVD. All of the above potential clinical applications require further studies to validate methods of assay and proof clinical benefits.

Abstract
Atherosclerosis is the leading cause of death worldwide and leukocyte recruitment is a key element of this phenomenon, thus allowing immune cells to enter the arterial wall. There, in concert with accumulating lipids, the invading leukocytes trigger a plethora of inflammatory responses which promote the influx of additional leukocytes and lead to the continued growth of atherosclerotic plaques. The recruitment process follows a precise scheme of tethering, rolling, firm arrest, crawling and transmigration and involves multiple cellular and subcellular players. This review aims to provide a comprehensive up-to-date insight into the process of leukocyte recruitment relevant to atherosclerosis, each from the perspective of endothelial cells, monocytes and macrophages, neutrophils, T lymphocytes and platelets. In addition, therapeutic options targeting leukocyte recruitment into atherosclerotic lesions-or potentially arising from the growing body of insights into its precise mechanisms-are highlighted.

Abstract
Extracellular vesicles (EVs) are emerging as key players in different stages of atherosclerosis. Here we provide evidence that EVs released by mixed aggregates of monocytes and platelets in response to TNF‐α display pro‐inflammatory actions on endothelial cells and atherosclerotic plaques. Tempering platelet activation with Iloprost, Aspirin or a P2Y12 inhibitor impacted quantity and phenotype of EV produced. Proteomics of EVs from cells activated with TNF‐α alone or in the presence of Iloprost revealed a distinct composition, with interesting hits like annexin‐A1 and gelsolin. When added to human atherosclerotic plaque explants, EVs from TNF‐α stimulated monocytes augmented release of cytokines. In contrast, EVs generated by TNF‐α together with Iloprost produced minimal plaque activation. Notably, patients with coronary artery disease that required percutaneous coronary intervention had elevated plasma numbers of monocyte, platelet as well as double positive EV subsets. In conclusion, EVs released following monocyte/platelet activation may play a potential role in the development and progression of atherosclerosis. Whereas attenuating platelet activation modifies EV composition released from monocyte/platelet aggregates, curbing their pro‐inflammatory actions may offer therapeutic avenues for the treatment of atherosclerosis.

Abstract
Background: Monocyte subsets in humans, i.e., classical (CM), intermediate (IM), and non-classical monocytes (NCM), are thought to differentially contribute to the pathogenesis of atherosclerosis, the leading cause of cardiovascular disease (CVD). However, the association between monocyte subsets and cardiometabolic disorders and CVD is not well-understood. Thus, the aim of the current systematic review and meta-analysis was to evaluate recent findings from clinical studies that examined the association between the distribution of monocyte subsets in subjects with cardiometabolic disorders and CVD compared to healthy controls. Methods: Articles were systematically searched in CINAHL, PubMed and Cochrane Library. Articles were independently screened and selected by two reviewers. Studies that reported the percentage of each monocyte subset were included in the systematic review and meta-analysis. For the meta-analysis, a random-effects model was used to generate pooled standardized mean differences (SMD) between subjects with cardiometabolic disorders and healthy controls. Results: A total of 1,693 articles were screened and 27 studies were selected for qualitative analyses. Among them, six studies were included in the meta-analysis. In total, sample size ranged from 22 to 135 and mean or median age from 22 to 70 years old. We found studies that reported higher percentage and number of IM and/or NCM in subjects with cardiometabolic disorders (9 out of 13 studies) and in subjects with CVD (11 out of 15 studies) compared to healthy controls. In the meta-analysis, the percentage of CM was lower [SMD = −1.21; 95% CI (−1.92, −0.50); P = 0.0009; I2 = 91%] and the percentage of IM [SMD = 0.56; 95% CI (0.23, 0.88); P = 0.0008; I2 = 65%] and NCM [SMD = 1.39; 95% CI (0.59, 2.19); P = 0.0007; I2 = 93%] were higher in subjects with cardiometabolic disorders compared to healthy controls. Conclusions: Individuals with cardiometabolic disorders and CVD may have a higher percentage of IM and NCM than healthy controls. Future studies are needed to evaluate the cause and biological significance of this potential altered distribution of monocyte subsets.

Abstract
Platelets are a heterogeneous small anucleate blood cell population with a central role both in physiological haemostasis and in pathological states, spanning from thrombosis to inflammation, and cancer. Recent advances in proteomic studies provided additional important information concerning the platelet biology and the response of platelets to several pathophysiological pathways. Platelets circulate systemically and can be easily isolated from human samples, making proteomic application very interesting for characterizing the complexity of platelet functions in health and disease as well as for identifying and quantifying potential platelet proteins as biomarkers and novel antiplatelet therapeutic targets. To date, the highly dynamic protein content of platelets has been studied in resting and activated platelets, and several subproteomes have been characterized including platelet-derived microparticles, platelet granules, platelet releasates, platelet membrane proteins, and specific platelet post-translational modifications. In this review, a critical overview is provided on principal platelet proteomic studies focused on platelet biology from signaling to granules content, platelet proteome changes in several diseases, and the impact of drugs on platelet functions. Moreover, recent advances in quantitative platelet proteomics are discussed, emphasizing the importance of targeted quantification methods for more precise, robust and accurate quantification of selected proteins, which might be used as biomarkers for disease diagnosis, prognosis and therapy, and their strong clinical impact in the near future.

Abstract
Background: Increased expressions of CD16 on classical monocytes precede their transition to intermediate monocytes. Thus far, the influence of lipids on the expression of CD14 and CD16 on monocyte subsets in coronary atherosclerosis (CA) remains unclear. The aim of this study was to investigate the underlying association between blood lipids and the expression of CD14 and CD16 on monocyte subsets. Methods: This study enrolled 112 healthy controls and 110 CA patients. Monocyte subsets [CD14++CD16- (classical), CD14++CD16+ (intermediate) and CD14+CD16++ (non-classical)] were analyzed by flow cytometry. Median fluorescent intensity (MFI) was used to evaluate the expression levels of CD14 and CD16 on monocyte subsets. Results: Compared with the control group, the expression of CD16 was significantly increased on all three monocyte subsets in the patient group. Correlation analysis revealed that serum HDL-C was inversely associated with the expression of CD16 on intermediate monocytes after Bonferroni correction in the control group. In addition, a significant decrease in classical monocytes and an increase in intermediate monocytes were detected in patients. In linear regression analysis, intermediate monocytes showed an inverse association with serum HDL-C in the control group. Although CD14 was correlated with serum TC and HDL-C, there was no statistical difference in CD14 expression between the two groups. Conclusion: Low serum HDL-C may induce upregulation of CD16 on classical monocytes, which may in turn lead to the increase of intermediate monocytes in coronary atherosclerosis patients.

Abstract
NEW FINDINGS What is the central question of this study? Are circulating monocyte markers correlated with their derived macrophage polarization patterns and coronary artery disease severity? What is the main finding and its importance? There was an inverse relationship between circulating CD16+ monocytes (high) and M2 macrophages (low) that marked coronary disease severity, and the differences in polarization of macrophages were seen despite a week of cell culture ex vivo. This study highlights the importance, and potential prognostic implications, of circulating monocyte and descendant macrophage phenotypes in coronary artery disease. ABSTRACT Monocytes and macrophages are central to atherosclerosis, but how they combine to mark progression of human coronary artery disease (CAD) is unclear. We tested whether patients' monocyte subtypes paired with their derived macrophage profiles were correlated with extent of CAD. Peripheral blood was collected from 40 patients undergoing cardiac catheterization, and patients were categorized as having no significant CAD, single vessel disease or multivessel disease according to the number of affected coronary arteries. Mononuclear cells were measured for the monocyte markers CD14 and CD16 by flow cytometry, and separate monocytes were cultured into macrophages over 7 days and measured for the polarization markers CD86 and CD206. At baseline, patients with a greater CAD burden were older, with higher rates of statin, β-blocker and antiplatelet drug use, whereas other characteristics were similar across the spectrum of coronary disease. CD16+ (both intermediate and non-classical) monocytes were elevated in patients with single vessel and multivessel disease compared with those without significant CAD (P < 0.05), whereas regulatory M2 macrophages (CD206+ ) were decreased in patients with single vessel and multivessel disease (P < 0.001). An inverse relationship between paired CD16+ monocytes and M2 macrophages marked CAD severity. On multivariable linear regression, CAD severity was associated, along with age and traditional cardiovascular risk factors, with CD16+ monocytes (directly) and M2 macrophages (inversely). Circulating monocytes may influence downstream polarization of lesional macrophages, and these measures of monocyte and macrophage subtypes hold potential as biomarkers in CAD.

Abstract
BACKGROUND Monocyte-platelet interaction may favor the development of a proatherogenic monocyte phenotype. It is still uncertain which of the 3 monocyte subpopulations interact with platelets to form monocyte-platelet aggregates (MPAs) in acute myocardial infarctions. The aim of our study was to evaluate the monocyte subsets, the percentage of MPAs and the involvement of monocyte subsets in MPA formation among patients with ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI), and compared to patients with stable angina (SA). METHODS Monocyte subsets and MPAs formation were measured in blood collected in 3.2% sodium citrate tubes by means of flow cytometry. RESULTS Classical, intermediate and nonclassical monocyte percentages were statistically different when comparing patients with STEMI and NSTEMI. Moreover, classical and intermediate monocytes were statistically different when comparing the STEMI and SA group; however, only the classical monocyte subset was found to be higher in the acute myocardial infarction group compared to the SA group. The percentage of MPAs was significantly higher in STEMI (50.1%) compared to NSTEMI (22.9%). We found no differences in the involvement of monocyte subsets in MPA formation between patients with STEMI and NSTEMI and in comparison with the SA group. CONCLUSIONS These findings suggest that the increase in circulating levels of classical monocytes in patients with STEMI as compared to NSTEMI reflects the severity of the acute event. The increased percentage of MPAs may favor the development of STEMI compared to NSTEMI.

Abstract
Immune cells were traditionally considered as major pro-inflammatory contributors. Recent advances in molecular immunology prove that immune cell lineages are composed of different subsets capable of a vast array of specialized functions. These immune cell subsets share distinct duties in regulating innate and adaptive immune functions and contribute to both immune activation and immune suppression responses in peripheral tissue. Here, we summarized current understanding of the different subsets of major immune cells, including T cells, B cells, dendritic cells, monocytes, and macrophages. We highlighted molecular characterization, frequency, and tissue distribution of these immune cell subsets in human and mice. In addition, we described specific cytokine production, molecular signaling, biological functions, and tissue population changes of these immune cell subsets in both cardiovascular diseases and cancers. Finally, we presented a working model of the differentiation of inflammatory mononuclear cells, their interaction with endothelial cells, and their contribution to tissue inflammation. In summary, this review offers an updated and comprehensive guideline for immune cell development and subset differentiation, including subset characterization, signaling, modulation, and disease associations. We propose that immune cell subset differentiation and its complex interaction within the internal biological milieu compose a “pathophysiological network,” an interactive cross-talking complex, which plays a critical role in the development of inflammatory diseases and cancers.

Abstract
The immune effects of platelets and platelet-leukocyte aggregation are increasingly recognized. We studied the occurrence of platelet-monocyte aggregation (PMA) in patients with pulmonary tuberculosis (TB), the processes underlying PMA and consequences for cytokine responses. In a cross-sectional study involving 65 Tanzanian TB patients in different phases of treatment and 29 healthy controls, TB patients had a significantly higher PMA. This increased PMA in TB patients was associated with increased monocyte CCR5, CD16 expression and PF4, but not with increased membrane-expressed or soluble P-selectin expression. These findings were confirmed in vitro: whereas incubation of whole blood with Mycobacterium tuberculosis (Mtb) did not activate platelets, monocytes became activated with higher CD11b, CD16 and CCR5 expression, but this was independent of platelet-monocyte interaction. Still, platelets had an anti-inflammatory effect on cytokine responses as peripheral blood mononuclear cells (PBMC) incubated with Mtb in the presence of platelets produced less interleukin (IL)-1β, tumor necrosis factor-α, IL-6 and interferon-γ and more IL-10. In conclusion, increased PMA during TB infection is caused by monocyte and not platelet activation. By counteracting the Mtb-induced pro-inflammatory leukocyte response, platelets may protect against excessive tissue damage, but may also compromise the production of protective cytokines, such as IFNƴ and TNFα.

Abstract
BACKGROUND Monocyte-platelet aggregates (MPAs) form when Mon1, Mon2 or Mon3 monocyte subsets adhere to platelets. They are pathophysiologically linked to coronary artery disease (CAD). However, their individual roles in the occurrence of diffuse CAD remain unknown. MATERIALS AND METHODS Peripheral blood from 50 patients with diffuse CAD, 40 patients with focal CAD and 50 age-matched patients with normal coronary arteries was analysed by flow cytometry to quantify MPAs associated with individual monocyte subsets. Cutaneous forearm microcirculation was assessed using laser Doppler flowmetry at rest and after iontophoresis of acetylcholine (endothelium-dependent vasodilation) and sodium nitroprusside (endothelium-independent vasodilation) at 100 μA for 60 seconds. Patients with CAD had repeat assessment at 6 and 12 months. RESULTS Baseline counts of MPAs with Mon2 subset (CD14++CD16+CC2+ monocytes) were significantly higher in patients with diffuse CAD compared to focal CAD (P = .001) and patients without CAD (P = .006). On multivariate regression, MPAs with Mon2 independently predicted diffuse CAD (odds ratio 1.10, 95% confidence interval 1.02-1.19, P = .01) and correlated negatively with endothelium-dependent microvascular vasodilation (r = -.37, P = .008), an association which persisted after adjustment for covariates. Longitudinal observation confirmed the persistence of an inverse relationship between MPAs with Mon2 and endothelium-dependent microvascular function. CONCLUSION Monocyte-platelet aggregates with Mon2 are increased in patients with diffuse CAD and therefore could represent an important contributor to accelerated coronary atherosclerotic progression by a mechanism involving microvascular endothelial dysfunction.

Abstract
The receptor EMMPRIN is involved in the development and progression of cardiovascular diseases and in the pathogenesis of myocardial infarction. There are several binding partners of EMMPRIN mediating the effects of EMMPRIN in cardiovascular diseases. EMMPRIN interaction with most binding partners leads to disease progression by mediating cytokine or chemokine release, the activation of platelets and monocytes, as well as the formation of monocyte-platelet aggregates (MPAs). EMMPRIN is also involved in atherosclerosis by mediating the infiltration of pro-inflammatory cells. There is also evidence that EMMPRIN controls energy metabolism of cells and that EMMPRIN binding partners modulate intracellular glycosylation and trafficking of EMMPRIN towards the cell membrane. In this review, we systematically discuss these multifaceted roles of EMMPRIN and its interaction partners, such as Cyclophilins, in cardiovascular disease.

This study investigated how short-term intensive training (SIT) influences monocyte subset characteristics and exercise-induced monocyte and platelet aggregates (MPAs) following elective coronary bypass (CABG) in cardiac patients. Forty-nine patients hospitalised for CABG were randomised into SIT (N=26) and conventional training (CT, N=23) groups. The SIT subjects underwent supervised aerobic training at 80~120 % of the ventilatory anaerobic threshold based on sub-maximal exercise tests performed 7 days post-CABG for 20 sessions with two sessions/day and 30 min/session, which were completed within four weeks after surgery. The CT subjects performed light-intensity conditioning exercise for ≤4 sessions. Resting and maximal exercise-mediated monocyte characteristics and MPA were determined before and following intervention. The SIT group had a larger improvement in ventilation efficiency and anaerobic threshold than the CT group; the SIT group exhibited larger reductions in blood monocyte subtypes 1 and 2 (Mono1 and 2) counts at rest than the CT group; the SIT group but not the CT group exhibited attenuated formation of Mono1/platelet hetero-aggregation (MPA1) and CD42b expression on Mono1/2 caused by strenuous exercise; and plasma levels of macrophage inflammatory protein-1β and soluble P-selectin showed similar trends as Mono1/2 and MPA1, respectively. In conclusion, SIT modestly improved aerobic capacity in patients following CABG. Moreover, SIT simultaneously ameliorated the CD42b expression of Mono1/2 cells and maximal exercise-induced MPA1, which may reduce the risk of inflammatory thrombosis.

Abstract
Despite falling age-adjusted mortality rates coronary artery disease (CAD) remains the leading cause of death worldwide. Advanced diffuse CAD is becoming an important entity of modern cardiology as more patients with historical revascularisation no longer have suitable anatomy for additional procedures. Advances in the treatment of diffuse obstructive CAD are hampered by a poor understanding of its development. Although the likelihood of developing clinically significant (obstructive) CAD is linked to traditional risk factors, the morphology of obstructive CAD among individuals is highly variable - some patients have diffuse stenotic disease, while others have a focal stenosis. This is challenging to explain in mechanistic terms as vascular endothelium is equally exposed to injury stimulants. Patients with diffuse disease are at high risk of adverse outcomes, particularly if unsuitable for revascularisation. We searched multiple electronic databases (MEDLINE, EMBASE and the Cochrane Database) and reviewed the epidemiology, pathogenesis and prognosis relating to advanced diffuse CAD with particular focus on the role of endothelial shear stress, large artery stiffness, monocyte subsets and circulating microparticles. Key messages Although traditional CAD risk factors correlate strongly with disease severity, significant individual variation in disease morphology exists. Advanced, diffuse CAD is difficult to treat effectively and can significantly impair quality of life and increases mortality. The pathophysiology associated with the progression of CAD is the result of complex maladaptive interaction between the endothelium, cells of the immune system and patterns of blood flow.

Abstract
The formation of monocyte-platelet aggregates and neutrophil-platelet aggregates (MPA and NPA, respectively) is influenced by inflammation, but also might contribute to an exacerbation of inflammatory responses in atherosclerotic plaque. The purpose of this study was to analyze MPA and NPA proportions in regard to different stages of peripheral arterial disease (PAD). Forty-five patients with intermittent claudication (IC) (3 groups: Rutherford (R)-1, R-2, and R-3; each n = 15), 20 patients with critical limb ischemia (CLI) (Rutherford 5 (40%) and 6 (60%)), and 20 healthy controls were studied. Analyses of monocyte (Mon) subpopulations (CD14++CD16- (classical) Mon1, CD14++CD16+ (intermediate) Mon2, CD14+CD16++ (non-classical) Mon3), MPA, and NPA was performed from whole blood by flow cytometry. Controls showed an increased proportion of the Mon1 subpopulation (p < 0.001), whereas CLI patients showed a significant increase of the Mon2 subpopulation compared to controls, R-1, or R-2 patients (p < 0.0001). For the Mon3 subpopulation, CLI and R-3 patients showed an increased proportion (p < 0.05). MPA formation with the proinflammatory Mon2 and Mon3 subpopulations was increased in CLI patients (both p < 0.01). Similarly, NPA was significantly increased in CLI patients (p < 0.05). Serological markers of inflammation and procoagulation (fibrinogen [r = 0.459, p < 0.001], soluble triggering receptor expressed on myeloid cells (sTREM-1) [r = 0.237, p < 0.05] and P-Selectin [r = 0.225, p < 0.05]) correlated directly with MPA formation on the Mon2 subpopulation. We found an association of inflammatory and procoagulatory markers with increased formation of MPA on the Mon2 subpopulation. Since R-3 patients also had significantly increased MPA, one can speculate that the inflammatory burden might promote an aggravation of the disease.

Abstract
Pathogens-induced platelet activation contributes to inflammation in cardiovascular diseases, but underlying mechanisms remain elusive. Staphylococcal superantigen-like protein 5 (SSL5) is a known activator of platelets. Here we examined whether SSL5 is implicated in Staphylococcus aureus (S. aureus)-induced inflammation and potential mechanisms involved. As expected, we show that SSL5 activates human platelets and induces generation of platelet microparticles (PMPs). Flow cytometry and scanning electron microscopy studies demonstrate that SSL5-induced PMPs (SSL5-PMPs) bind to monocytes, causing aggregate formation. In addition, SSL5-PMPs provoke monocyte expression and release of inflammatory mediators, including interleukin-1β (IL-1β), tumour necrosis factor-α (TNFα), monocyte chemoattractant protein-1 (MCP-1) and matrix metalloproteinase-9 (MMP-9) in a dose- and time-dependent manner. SSL5-PMPs also enhance MCP-1-induced monocyte migration. Blockade of CD40 and CD40 ligand (CD40L) interactions with neutralising antibodies significantly reduce monocyte release of inflammatory mediators and migration induced by SSL5-PMPs. SiRNA-mediated silencing of CD40 or TNF receptor (TNFR)-associated factor 6 (TRAF6) gene largely abrogates phosphorylation and nuclear translocation of NFκB (p65). In conclusion, SSL5 provokes the release of inflammatory mediators in monocytes, at least in part, via PMPs-mediated activation of the CD40/TRAF6/NFκB signalling pathway, though it normally inhibits leukocyte function. Our findings thus reveal a novel mechanism by which S. aureus induces inflammation.

Abstract
Psoriasis patients exhibit an increased risk of death by cardiovascular disease (CVD) and have elevated levels of circulating intermediate (CD14(++)CD16(+)) monocytes. This elevation could represent evidence of monocyte dysfunction in psoriasis patients at risk for CVD, as increases in circulating CD14(++)CD16(+) monocytes are predictive of myocardial infarction and death. An elevation in the CD14(++)CD16(+) cell population has been previously reported in patients with psoriatic disease, which has been confirmed in the cohort of our human psoriasis patients. CD16 expression was induced in CD14(++)CD16(-) classical monocytes following plastic adhesion, which also elicited enhanced β2 but not β1 integrin surface expression, suggesting increased adhesive capacity. Indeed, we found that psoriasis patients have increased monocyte aggregation among circulating PBMCs, which is recapitulated in the KC-Tie2 murine model of psoriasis. Visualization of human monocyte aggregates using imaging cytometry revealed that classical (CD14(++)CD16(-)) monocytes are the predominant cell type participating in these aggregate pairs. Many of these pairs also included CD16(+) monocytes, which could account for apparent elevations of intermediate monocytes. Additionally, intermediate monocytes and monocyte aggregates were the predominant cell type to adhere to TNF-α- and IL-17A-stimulated dermal endothelium. Ingenuity Pathway Analysis demonstrated that monocyte aggregates have a distinct transcriptional profile from singlet monocytes and monocytes following plastic adhesion, suggesting that circulating monocyte responses to aggregation are not fully accounted for by homotypic adhesion, and that further factors influence their functionality.

Abstract
UNLABELLED Atherosclerosis is an inflammatory disease associated with the formation of atheroma plaques likely to rupture in which platelets are involved both in atherogenesis and atherothrombosis. The rupture is linked to the molecular composition of vulnerable plaques, causing acute cardiovascular events. In this study we propose an original targeted contrast agent for molecular imaging of atherosclerosis. Versatile USPIO (VUSPIO) nanoparticles, enhancing contrast in MR imaging, were functionalised with a recombinant human IgG4 antibody, rIgG4 TEG4, targeting human activated platelets. The maintenance of immunoreactivity of the targeted VUSPIO against platelets was confirmed in vitro by flow cytometry, transmission electronic and optical microscopy. In the atherosclerotic ApoE(-/-) mouse model, high-resolution ex vivo MRI demonstrated the selective binding of TEG4-VUSPIO on atheroma plaques. It is noteworthy that the rationale for targeting platelets within atherosclerotic lesions is highlighted by our targeted contrast agent using a human anti-αIIbβ3 antibody as a targeting moiety. FROM THE CLINICAL EDITOR Current clinical assessment of atherosclerotic plagues is suboptimal. The authors in the article designed functionalized superparamagnetic iron oxide nanoparticles with TEG4, a recombinant human antibody, to target activated platelets. By using MRI, these nanoparticles can be utilized to study the process of atheroma pathogenesis.

Abstract
This study aimed to examine the mechanisms of cellular activation by small-size platelet microparticles (sPMP) and to present the performance of high-resolution flow cytometry for the analysis of subcellular entities from different origins. Plasma counts of sPMP were analysed in coronary artery disease patients (n = 40) and healthy controls (n = 40). The effect of sPMP and platelet debris (PD) in pathophysiologically relevant doses on platelet and monocyte activation parameters and thrombogenesis was investigated via flow cytometry and thromboelastometry. New generation flow cytometry identifies differences in size, levels and surface molecules of sPMP derived in the absence of stimulus, thrombin activation and platelet disruption. Addition of sPMP resulted in platelet degranulation and P-selectin redistribution to the membrane (P = 0·019) in a dose and time-dependent manner. Blood clotting time decreased after addition of sPMP (P = 0·005), but was not affected by PD. Blocking P-selectin (CD62P) in sPMP markedly reverted the effect on thrombus kinetics (P = 0·035). Exposure to sPMP stimulated monocyte expression of intercellular adhesion molecule-1 (P < 0·03) and decreased monocyte interleukin-6 receptor density (P < 0·01). These results implicate sPMP as a direct source of downstream platelet and monocyte activation. In pathological coronary artery disease conditions, higher levels of sPMP favour a prothrombotic state, partly through P-selectin expression.
