Abstract
AIM JNK pathway-associated phosphatase (JKAP) regulates T cell-mediated immunity and inflammation, which are involved in atherosclerosis pathogenesis. This study investigated the effects of JKAP on T-helper (Th) cell polarization, inflammation, and atherosclerotic progression. METHODS Serum JKAP levels were measured in 30 patients with coronary heart disease (CHD) and 30 controls. CHD blood naïve CD4+ T cells were acquired, followed by JKAP overexpression and knockdown with or without treatment with PD98059 (ERK inhibitor) or BAY-11-7082 (NF-κB inhibitor) in vitro. CD4+ T-cell conditional JKAP ablation mice were established in vivo, followed by the construction of an atherosclerosis model. RESULTS JKAP was reduced and negatively correlated with the Gensini score, CRP, Th1 cells, Th17 cells, and proinflammatory cytokines in patients with CHD. In vitro, JKAP overexpression suppressed Th1 and Th17 cell differentiation and proinflammatory cytokines, whereas JKAP knockdown exerted the opposite effect; however, JKAP modification did not affect Th2 cell differentiation. Interestingly, JKAP negatively regulated the ERK and NF-κB pathways; meanwhile, the PD98059 and BAY-11-7082 treatments repressed Th1 and Th17 cell differentiation, and attenuated the effect of JKAP knockdown on these indices. In vivo, conditional CD4+ T-cell JKAP ablation increased Th1 and Th17 cell polarization in the spleen, lymph node, blood, and/or aortic root. Furthermore, CD4+ T-cell conditional JKAP ablation exaggerated atherosclerotic lesions in the aorta, elevated CD4+ cell infiltration and proinflammatory cytokines in the aortic root, and activated the ERK and NF-κB pathways in the aortic root. CONCLUSION JKAP ablation facilitates atherosclerosis progression by promoting Th1 and 17 polarization and inflammation through regulation of the ERK and NF-κB pathways.

Abstract
Atherosclerosis involves both innate and adaptive immunity. Here, we provide an overview of the role of regulatory T (Treg) cells in atherosclerotic diseases. Treg cells and their inhibitory cytokines, IL-10 and TGF-β, have been identified in atherosclerotic lesions and to inhibit progression through lipoprotein metabolism modulation. Treg cells have also been found to convert to T follicular helper (Tfh) cells and promote atherosclerosis progression. Treg cell involvement in different stages of atherosclerotic progression and Treg cell-mediated modulation of plaque development occurs via inflammation suppression and atheroma formation has been focused. Moreover, existing knowledge suggests that Treg cells are likely involved in the pathology of other specific circumstances including in-stent restenosis, neointimal hyperplasia, vessel graft failure, and ischemic arterial injury; however, there remain gaps regarding their specific contribution. Hence, advancements in the knowledge regarding Treg cells in diverse aspects of atherosclerosis offer translational significance for the management of atherosclerosis and associated diseases.

Abstract
Aim To analyze the relationship between serum concentrations of high-sensitivity C-reactive protein (hsCRP) in dynamics and development of restenosis at 12 months following elective coronary stent placement (CSP).Material and methods The key role in atherogenesis, neointimal proliferation and restenosis belongs to inflammation. This study included 91 patients (median age, 60 [56; 66] years) with stable exertional angina after an elective CSP using second-generation stents. Follow-up coronarography was performed for 60 patients at 12 months. Concentration of hsCRP was measured immediately prior to CSP and at 1, 3, 6, and 12 months after CSP. Restenosis of the stented segment (50% or more narrowing of the stented segment or a 5-mm vessel segment proximally or distally adjacent to the stented segment) was observed in 8 patients.Results According to results of the ROC analysis, the increase in hsCRP concentration >0.9 mg/l (>25%) at one month after CSP had the highest predictive significance with respect of restenosis (area under the ROC curve, 0.89 at 95 % confidence interval (CI) from 0.79 to 0.99; sensitivity, 87.5 %; specificity, 82.8 %; р=0.0005), which was superior to the absolute value of hsCRP concentration >3.0 mg/l (area under the ROC curve, 0.82 at 95 % CI from 0.68 to 0.96; р=0.0007).Conclusion Increased concentration of hsCRP ≥0.9 mg /l (≥25 %) at a month after CSP was associated with restenosis of the coronary artery stented segment.

Nutr Metab (Lond) 2020; 17:41. [PMID: 32508962 PMCID: PMC7251691 DOI: 10.1186/s12986-020-00461-z] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Accepted: 05/15/2020] [Indexed: 02/06/2023] Open
Abstract
Background Atherosclerosis (AS), which characterized with the accumulation of lipids on the vessel wall, is the pathological basis of many cardiovascular diseases (CVD) and seriously threatens human health. Resveratrol (RES) has been reported to be benefit for AS treatment. This research aimed to observe the effects of RES on AS induced by high-fat diet (HFD) and LPS in ApoE-/- mice and investigate the underlying mechanism. Methods ApoE-/- mice were fed with HFD companied with LPS to induce AS and RES was administrated for 20 weeks. Splenic CD4+ T cells were cultured and treated with anti-CD3/CD28 together with LPS, and RES was added. Serum lipids and the atherosclerotic areas of aortas were detected. The activation of CD4+ T cells were investigated both in vivo and in vitro and the expression of DNA methyltransferases (Dnmt) in CD4+ T cells were measured. Results In vivo, administration of RES prevented HFD and LPS induced dysfunction of serum lipids including TC (total cholesterol), TG (triglyceride), LDL-C (low density lipoprotein cholesterol) and HDL-C (high density lipoprotein cholesterol), ameliorated the thickened coronary artery wall and decreased the areas of atherosclerotic lesion on aortas. Besides, RES decreased the number of CD4+ T cells in peripheral blood, decreased the expression of CD25 and CD44, but not affected the expression of L-selectin (CD62L). In vitro, RES decreased the expression of Ki67, CD25 and CD44 in CD4+ T cells. Moreover, RES increased the secretion of IL-2, IL-10 and TGF-β1, decreased IL-6. In addition, RES decreased both the mRNA and protein level of Dnmt1 and Dnmt3b in CD4+ T cells. Conclusion These results indicated that RES ameliorated AS induced by HFD companied with LPS in ApoE-/- mice, inhibited the proliferation and activation of CD4+ T cells and regulated the expression of Dnmt1 and Dnmt3b.

Abstract
Aim Immune and inflammatory reactions contribute to the progression of atherosclerosis. The walls of the different arteries and segments of the arteries have heterogeneous haemodynamic and histological features. We aimed to explore the relationship between the circulating T-cell subsets and the abundance of carotid atherosclerosis in different segments of carotid arteries. Methods 70 patients underwent ultrasound duplex scanning to determine the degree of stenosis of the common carotid artery (CCA), the CCA bifurcation or the internal carotid artery (ICA). The blood frequencies of T-, B-, NK-cells, regulatory T cells (Treg), activated T-helpers (Th), IL10-producing Th, Th1 and Th17, as well as blood levels of hsCRP, sCD25, IL10 and IL17a were assessed. Results The frequencies of Th17 were increased in patients with ICA stenosis >35% and >50% vs. patients with ICA stenosis <35%. Th17 blood level ≥0.55 % of lymphocytes was associated with more severe stenosis of ICA (OR 4.3 (1.0–17.6), p < 0.05 for ICA stenosis of 35–50% and 6.8 (1.3–35.0), p < 0.05 for ICA stenosis >50%). BMI positively correlated with the CCA bifurcation stenosis degree (r = 0.33, p < 0.05). Conclusion The severity of ICA stenosis can be associated with the circulating Th17 level.

Targeting Early Atherosclerosis: A Focus on Oxidative Stress and Inflammation. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:8563845.

Abstract
Atherosclerosis is a chronic vascular inflammatory disease associated to oxidative stress and endothelial dysfunction. Oxidation of low-density lipoprotein (LDL) cholesterol is one of the key factors for the development of atherosclerosis. Nonoxidized LDL have a low affinity for macrophages, so they are not themselves a risk factor. However, lowering LDL levels is a common clinical practice to reduce oxidation and the risk of major events in patients with cardiovascular diseases (CVD). Atherosclerosis starts with dysfunctional changes in the endothelium induced by disturbed shear stress which can lead to endothelial and platelet activation, adhesion of monocytes on the activated endothelium, and differentiation into proinflammatory macrophages, which increase the uptake of oxidized LDL (oxLDL) and turn into foam cells, exacerbating the inflammatory signalling. The atherosclerotic process is accelerated by a myriad of factors, such as the release of inflammatory chemokines and cytokines, the generation of reactive oxygen species (ROS), growth factors, and the proliferation of vascular smooth muscle cells. Inflammation and immunity are key factors for the development and complications of atherosclerosis, and therefore, the whole atherosclerotic process is a target for diagnosis and treatment. In this review, we focus on early stages of the disease and we address both biomarkers and therapeutic approaches currently available and under research.
