Abstract
Pulmonary arterial hypertension (PAH), corresponding to group 1 of pulmonary hypertension classification, is a rare disease with a major prognostic impact on morbidity and mortality. PAH can be either primary in idiopathic and heritable forms or secondary to other conditions including connective tissue diseases (CTD-PAH). Within CTD-PAH, the leading cause of PAH is systemic sclerosis (SSc) in Western countries, whereas systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD) are predominantly associated with PAH in Asia. Although many advances have been made during the last two decades regarding classification, definition early screening and risk stratification and therapeutic aspects with initial combination treatment, the specificities of CTD-PAH are not yet clear. In this manuscript, we review recent literature data regarding the updated definition and classification of PAH, pathogenesis, epidemiology, detection, prognosis and treatment of CTD-PAH.

Abstract
Pulmonary hypertension (PH) is a malignant disease with progressive increase of pulmonary vascular pressure, which eventually leads to right heart failure. More and more evidences show that immune cells and inflammation play an important role in the occurrence and development of PH. In the context of pulmonary vascular diseases, immune cells migrate into the walls of the pulmonary vascular system. This leads to an increase in the levels of cytokines and chemokines in both the bloodstream and the surrounding tissues of the pulmonary vessels. As a result, new approaches such as immunotherapy and anti-inflammatory treatments are being considered as potential strategies to halt or potentially reverse the progression of PH. We reviewed the potential mechanisms of immune cells, cytokines and chemokines in PH development. The potential relationship of vascular cells or bone morphogenetic protein receptor 2 (BMPR2) in immune regulation was also expounded. The clinical application and future prospect of immunotherapy were further discussed.

Abstract
Pulmonary hypertension (PH) comprises five groups of serious clinical entities characterized by pulmonary artery vasoconstriction and vascular remodeling leading to right heart failure and death. In addition to vascular remodeling, recruitment and exaggerated accumulation of several perivascular inflammatory cells is also observed, including macrophages, monocytes, T and B-lymphocytes, dendritic cells and mast cells distributed in pulmonary perivascular spaces and around remodeling pulmonary vessels. Current pulmonary arterial hypertension (PAH)-targeted therapies aim to improve functional capacity, pulmonary hemodynamic conditions, and delay disease progression. Nevertheless, PAH remains incurable, with a poor prognosis and is often refractory to drug therapy, highlighting the need for further research. In the last three decades, the best pathophysiological understanding of PAH has allowed for progression from a disease of little-known pathogenesis, without specific and effective therapy to expanding the arsenal of drugs on a cellular, genetic and molecular basis. This article provides an overview on current knowledge and progress in recent advances in pharmacological therapy in PAH.

Abstract
Pulmonary arterial hypertension (PAH) is a rare condition that is characterised by a progressive increase of pulmonary vascular resistances that leads to right ventricular failure and death, if untreated. The underlying narrowing of the pulmonary vasculature relies on several independent and interdependent biological pathways, such as genetic predisposition and epigenetic changes, imbalance of vasodilating and vasoconstrictive mediators, as well as dysimmunity and inflammation that will trigger endothelial dysfunction, smooth muscle cell proliferation, fibroblast activation and collagen deposition. Progressive constriction of the pulmonary vasculature, in turn, initiates and sustains hypertrophic and maladaptive myocardial remodelling of the right ventricle. In this review, we focus on the role of inflammation and dysimmunity in PAH which is generally accepted today, although existing PAH-specific medical therapies still lack targeted immune-modulating approaches.

Abstract
Pulmonary arterial hypertension (PAH) is a chronic disease characterized by increased pulmonary artery pressure which if left untreated, can lead to poor quality of life and ultimately death. It is a group of conditions and includes idiopathic PAH, familial/hereditary PAH and associated PAH. The condition has been studied for many years and its association with the immune system and in particular autoimmunity has been investigated. The mechanisms for the pathobiology of PAH are unclear although research has highlighted the role of adaptive and innate immune systems in its development. Diagnostics and therapeutic approaches range from cytokine treatments to the use of immunomodulating drugs, although there is still scope for improvements in the field. This article discusses the mechanisms linked to PAH, its association with other conditions and recent therapeutic interventions.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive and devastating disease characterized by pulmonary artery vasoconstriction and vascular remodeling leading to vascular rarefaction with elevation of pulmonary arterial pressures and pulmonary vascular resistance. Often PAH will cause death from right heart failure. Current PAH-targeted therapies improve functional capacity, pulmonary hemodynamics and reduce hospitalization. Nevertheless, today PAH still remains incurable and is often refractory to medical therapy, underscoring the need for further research. Over the last three decades, PAH has evolved from a disease of unknown pathogenesis devoid of effective therapy to a condition whose cellular, genetic and molecular underpinnings are unfolding. This article provides an update on current knowledge and summarizes the progression in recent advances in pharmacological therapy in PAH.

Abstract
Pulmonary arterial hypertension (PAH) is a relatively rare disease, but, today, its incidence tends to increase. The severe course of the disease and poor patient survival rate make PAH a major diagnostic and therapeutic challenge. For this reason, a thorough understanding of the pathogenesis of the disease is essential to facilitate the development of more effective therapeutic targets. Research shows that the development of PAH is characterized by a number of abnormalities within the immune system that greatly affect the progression of the disease. In this review, we present key data on the regulated function of immune cells, released cytokines and immunoregulatory molecules in the development of PAH, to help improve diagnosis and targeted immunotherapy.

Abstract
Pulmonary arterial hypertension (PAH) is a severe cardiovascular disease that is caused by the progressive occlusion of the distal pulmonary arteries, eventually leading to right heart failure and death. Almost 40% of patients with PAH are iron deficient. Although widely studied, the mechanisms linking between PAH and iron deficiency remain unclear. Here we review the mechanisms regulating iron homeostasis and the preclinical and clinical data available on iron deficiency in PAH. Then we discuss the potential implications of iron deficiency on the development and management of PAH.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive cardiovascular disease with high mortality. However, there were no efficient medical drugs for PAH to enormously improve the survival and quality of life measures. The present study aimed to explore the protective effect of baicalin against experimental PAH in vivo and vitro. All the experimental rats received intraperitoneal injection of monocrotaline (MCT) to induce PAH model. Baicalin was given by intragastric administration from 2 days after MCT injection. Forty animals were randomly divided into four groups: Control, MCT, saline-, and baicalin-treated groups (n = 10 in each). Post-operation, hemodynamic data, and index of right ventricular hypertrophy (RVHI) were recorded to evaluate the inhibition of baicalin on MCT-induced PAH. Furthermore, pulmonary artery smooth muscle cells (PASMCs) model induced by tumor necrosis factor-α (TNF-α) was used to observe the inhibition of vascular cells proliferation in vitro. The results demonstrated that baicalin significantly attenuated MCT-induced right ventricular systolic pressure (RVSP), the index of right ventricular hypertrophy, and vessel wall thickness; inhibit inflammatory and cell proliferation induced by MCT or TNF-α, respectively. In addition, we found that baicalin might protect against experimental PAH via regulating the TNF-α/BMPR2 signaling pathway.

Abstract
Pulmonary arterial hypertension (PAH) is a complex multifactorial disease with both genetic and environmental dynamics contributing to disease progression. Over the last decade, several studies have demonstrated the presence of genomic instability and increased levels of DNA damage in PAH lung vascular cells, which contribute to their pathogenic apoptosis-resistant and proliferating characteristics. In addition, the dysregulated DNA damage response pathways have been indicated as causal factors for the presence of persistent DNA damage. To understand the significant implications of DNA damage and repair in PAH pathogenesis, the current review summarizes the recent advances made in this field. This includes an overview of the observed DNA damage in the nuclear and mitochondrial genome of PAH patients. Next, the irregularities observed in various DNA damage response pathways and their role in accumulating DNA damage, escaping apoptosis, and proliferation under a DNA damaging environment are discussed. Although the current literature establishes the pertinence of DNA damage in PAH, additional studies are required to understand the temporal sequence of the above-mentioned events. Further, an exploration of different types of DNA damage in conjunction with associated impaired DNA damage response in PAH will potentially stimulate early diagnosis of the disease and development of novel therapeutic strategies.

Abstract
The adaptive immune response mediated by T lymphocytes is a well-established factor in the pathogenesis of pulmonary inflammation. Changes in the expression of various connexins (Cxs) or disruption of connexin-mediated cellular communication in T lymphocytes contribute to inflammation or tissue remodeling. The aim of the present study was to investigate the potential therapeutic value of blocking Cxs in a monocrotaline (MCT)-induced pulmonary inflammation rat model. Carbenoxolone (CBX) was used to inhibit connexin-mediated cellular communication. An MCT rat model was established by intraperitoneal (i.p.) injection of a single dose of MCT (60 mg/kg), and CBX treatment (20 µg/kg/day, i.p.) was initiated on the day following MCT treatment for 28 days. Vehicle-treated male Sprague-Dawley rats were used as the negative control. The MCT rat model was evaluated by measuring the pulmonary artery flow acceleration time and right ventricular hypertrophy index (RVHI). Histopathological features of the lung tissues and pulmonary arteriolar remodeling were assessed. The proportions of T lymphocyte subtypes, Cx40/cx43 expression in the T cell subtypes and the cytokine levels in the plasma and the lung tissues were also analyzed. Pharmacological inhibition of Cxs using CBX attenuated MCT-induced right ventricular hypertrophy, pulmonary arteriolar remodeling, lung fibrosis and inflammatory cell infiltration by decreasing the RVHI, pulmonary arterial wall thickening, collagen deposition and pro-inflammatory cytokines production as well as CD3+ and CD4+ T cell accumulation in lung tissues of MCT-treated rats. Furthermore, flow cytometry analysis revealed that CBX may inhibit MCT-induced Cx40 and Cx43 expression in CD4+ and CD8+ T lymphocytes in lung tissues. The present study provides evidence that pharmacological inhibition of Cxs may attenuate MCT-induced pulmonary arteriolar remodeling and pulmonary inflammatory response, at least in part, by decreasing Cx expression. The results highlight the critical role of Cxs in T lymphocytes in the MCT-induced pulmonary inflammatory response and that targeting of Cxs may be a potential therapeutic method for treating pulmonary inflammatory diseases.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive disorder characterized by vascular remodeling, endothelial cell (EC) dysfunction, and inflammation. The roles of microRNAs have received much critical attention. Thus, this study was attempted to show the biological function of miR-181a/b-5p (miR-181a/b) in monocrotaline (MCT)-induced PAH. Here, rats injected with MCT were used as PAH models. The expression of miR-181a/b and its effect on PAH pathologies were examined using miR-181a/b overexpression lentivirus. A luciferase reporter analysis was performed to measure the relationships between miR-181a/b and endocan. Additionally, primary rat pulmonary arterial endothelial cells (rPAECs) treated with tumor necrosis factor-α (TNF-α) were employed to further validate the regulatory mechanism of miR-181a/b in vitro. Our results showed that miR-181a/b expression was reduced in PAH, and its upregulation significantly attenuated the short survival period, right ventricular systolic pressure and mean pulmonary artery pressure increments, right ventricular remodeling, and lung injury. Furthermore, the increase of intercellular cell adhesion molecule-1 (ICAM1) and vascular cell adhesion molecule-1 (VCAM1) in PAH rats was inhibited by miR-181a/b overexpression. Similarly, our in vitro results showed that inducing miR-181a/b suppressed TNF-α-stimulated increase of ICAM1 and VCAM1 in rPAECs. Importantly, the increased expression of endocan in PAH model or TNF-α-treated rPAECs was restored by miR-181a/b upregulation. Further analysis validated the direct targeting relationships between miR-181a/b and endocan. Collectively, this study suggests that miR-181a/b targets endocan to ameliorate PAH symptoms by inhibiting inflammatory states, shedding new lights on the prevention and treatment of PAH.

Abstract
Inflammation in pulmonary arterioles initiates and maintains pathological processes in pulmonary arterial hypertension (PAH), and inhibition of it attenuates PAH development. Grape seed proanthocyanidin (GSP) is believed to be effective in protecting vascular system via inhibiting inflammation, while its effect on pulmonary circulation remains inconclusive. In this study, we made observations in monocrotaline (MCT)-induced PAH rats and found decreases in mean pulmonary arterial pressure, pulmonary vessel resistance, right ventricular hypertrophy index, percentage of medial wall thickness, percentage of medial wall area, and lung weight of wet and dry tissue ratio after GSP administration in vivo. At the cellular and molecular levels, we also found several effects of GSP on MCT-induced PAH: (a) endothelial nitric oxide synthase expression in lung tissue and plasma NO level were increased; (b) Ca2+ level in pulmonary arterial smooth muscle cell (PASMC) was decreased; (c) transcription of inflammatory factors such as myeloperoxidase, interleukin (IL)-1β, IL-6 and tumor necrosis factor alpha (TNF-α) was down-regulated in lung tissue; (d) nuclear factor-κB pathway was inhibited as IκBα was less phosphorylated; (e) TNFα-induced PASMC overproliferation could be inhibited. These results indicated a possible mechanism of GSP reversing pulmonary vascular remodeling and vascular contraction by inhibiting inflammation, and it may be useful for preventing PAH development.

Abstract
Pulmonary hypertension is a complex and fatal disease that lacks treatments. Its pathophysiology involves pulmonary artery hyperreactivity, endothelial dysfunction, wall remodelling, inflammation, and thrombosis, which could all depend on ORAI Ca2+ channels. We review the knowledge about ORAI channels in pulmonary artery and discuss the interest to target them in the treatment of pulmonary hypertension.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is characterized by the apoptosis resistance and hyperproliferation of pulmonary artery smooth muscle cells (PASMCs). Its pathogenesis has not been revealed. Here, we carried out experiments to investigate the functions of miR-140-5p and tumor necrosis factor-α (TNF-α). METHODS We selected GSE703 from Gene Expression Omnibus (GEO) Database to conduct microarray analysis using R software and Gene Set Enrichment Analysis (GSEA). Combing bioinformatics results, the upregulation of miR-140-5p inhibited PAH progression through targeting TNF-α. RNA expression was measured by quantitative real-time polymerase chain reaction (RT-qPCR) and protein level was measured by western blot analysis and enzyme-linked immunosorbent assays (ELISA). We conducted monocrotaline (MCT) injection to rats to form PAH animal models. The lung tissues were observed by hematoxylin-eosin (HE) staining and Sirius red-picric acid staining. Right ventricular systolic pressure (RVSP) and the ratio of right ventricle (RV)-to-left ventricle (LV) plus septum (S) weight (RV/[LV + S]) were measured in MCT-induced animal models. Overexpression of miR-140-5p and TNF-α were utilized to research the proliferation, migration, and phenotypic variation of hypoxia-mediated PASMCs. The binding between miR-140-5p and TNF-α 3'-untranslated region (3'-UTR) was confirmed via luciferase reporter assay. RESULTS Downregulation of miR-140-5p and upregulation of TNF-α were observed in PAH rat model and hypoxia-mediated PASMCs. And we proved that overexpression of miR-140-5p could suppress the proliferation, migration, and phenotypic variation of PASMCs, therefore inhibiting PAH pathogenesis. Luciferase assay verified that miR-140-5p targeted TNF-α directly. A converse correlation was also shown between miR-140-5p and TNF-α in PASMCs. CONCLUSIONS miR-140-5p and TNF-α are important regulators in PAH pathology and may serve as a therapeutic target for PAH.

Abstract
The pathobiology of pulmonary arterial hypertension (PAH) is complex and incompletely understood. Although three pathogenic pathways have been relatively well characterised, it is widely accepted that dysfunction in a multitude of other cellular processes is likely to play a critical role in driving the development of PAH. Currently available therapies, which all target one of the three well-characterised pathways, provide significant benefits for patients; however, PAH remains a progressive and ultimately fatal disease. The development of drugs to target alternative pathogenic pathways is, therefore, an attractive proposition and one that may complement existing treatment regimens to improve outcomes for patients. Considerable research has been undertaken to identify the role of the less well-understood pathways and in this review we will highlight some of the key discoveries and the potential for utility as therapeutic targets.

Abstract
Trichloroethylene (TCE) is a chlorinated solvent that has been used widely around the world in the twentieth century for metal degreasing and dry cleaning. Although TCE displays general toxicity and is classified as a human carcinogen, the association between TCE exposure and respiratory disorders are conflicting. In this review we aimed to systematically evaluate the current evidence for the respiratory effects of TCE exposure and the implications for the practicing clinician. There is limited evidence of an increased risk of lung cancer associated with TCE exposure based on animal and human data. However, the effect of other chlorinated solvents and mixed solvent exposure should be further investigated. Limited data are available to support an association between TCE exposure and respiratory tract disorders such as asthma, chronic bronchitis, or rhinitis. The most consistent data is the association of TCE with autoimmune and vascular diseases such as systemic sclerosis and pulmonary veno-occlusive disease. Although recent data are reassuring regarding the absence of an increased lung cancer risk with TCE exposure, clinicians should be aware of other potential respiratory effects of TCE. In particular, occupational exposure to TCE has been linked to less common conditions such as systemic sclerosis and pulmonary veno-occlusive disease.

Pulmonary vascular remodeling patterns and expression of general control nonderepressible 2 (GCN2) in pulmonary veno-occlusive disease. J Heart Lung Transplant 2017; 37:647-655.

Abstract
BACKGROUND Heritable pulmonary veno-occlusive disease (PVOD) is linked to mutations in the eukaryotic initiation factor 2 alpha kinase 4 (EIF2AK4) gene, leading to a loss of general control nonderepressible 2 (GCN2). The role of GCN2 expression in pulmonary vascular remodeling remains obscure. We sought to identify specific histologic and biologic features in heritable PVOD. METHODS Clinical data and lung histology of 24 PVOD patients (12 EIF2AK4 mutation carriers, 12 non-carriers) were submitted to systematic histologic analysis and semiautomated morphometry. GCN2 expression was quantified by Western blotting in 24 PVOD patients, 44 patients with pulmonary arterial hypertension (PAH; 23 bone morphogenetic protein receptor type II [BMPR2] mutation carriers, 21 non-carriers), and 3 experimental pulmonary hypertension models. RESULTS PVOD patients showed a significant decrease of pulmonary arterial patency (p < 0.0001) compared with healthy controls. Histology of EIF2AK4 mutation carriers was distinctive from non-carriers regarding (1) arterial remodeling, with significantly more severe intimal fibrosis (p = 0.001), less severe medial hypertrophy (p = 0.001), and (2) stronger muscular hyperplasia of interlobular septal veins (p = 0.002). GCN2 expression was abolished in heritable PVOD (p < 0.0001), but also importantly decreased in sporadic PVOD (p = 0.03) as well as in heritable (p = 0.002) and idiopathic PAH (p = 0.003); moreover, GCN2 was abolished in 2 experimental pulmonary hypertension models and importantly decreased in 1 model (p < 0.0001 for all models). CONCLUSIONS Pulmonary arterial remodeling in PVOD is present to an important extent. A significant decrease of GCN2 expression is a common denominator of all tested groups of PVOD and PAH, including their respective experimental models. Our results underline specific morphologic and biologic similarities between PAH and PVOD and let us consider both conditions rather in one large spectrum of disease than as two distinct and clear-cut entities.

Abstract
Pulmonary arterial hypertension (PAH) is a severe and incurable pulmonary vascular disease. One of the primary origins of PAH is pulmonary endothelial dysfunction leading to vasoconstriction, aberrant angiogenesis and smooth muscle cell proliferation, endothelial-to-mesenchymal transition, thrombosis and inflammation. Our objective was to study the epigenetic variations in pulmonary endothelial cells (PEC) through a specific pattern of DNA methylation. DNA was extracted from cultured PEC from idiopathic PAH (n = 11), heritable PAH (n = 10) and controls (n = 18). DNA methylation was assessed using the Illumina HumanMethylation450 Assay. After normalization, samples and probes were clustered according to their methylation profile. Differential clusters were functionally analyzed using bioinformatics tools. Unsupervised hierarchical clustering allowed the identification of two clusters of probes that discriminates controls and PAH patients. Among 147 differential methylated promoters, 46 promoters coding for proteins or miRNAs were related to lipid metabolism. Top 10 up and down-regulated genes were involved in lipid transport including ABCA1, ABCB4, ADIPOQ, miR-26A, BCL2L11. NextBio meta-analysis suggested a contribution of ABCA1 in PAH. We confirmed ABCA1 mRNA and protein downregulation specifically in PAH PEC by qPCR and immunohistochemistry and made the proof-of-concept in an experimental model of the disease that its targeting may offer novel therapeutic options. In conclusion, DNA methylation analysis identifies a set of genes mainly involved in lipid transport pathway which could be relevant to PAH pathophysiology.

Abstract
BACKGROUND Pulmonary arterial hypertension is a severe and progressive disease, a hallmark of which is pulmonary vascular remodeling. Nicotinamide phosphoribosyltransferase (NAMPT) is a cytozyme that regulates intracellular nicotinamide adenine dinucleotide levels and cellular redox state, regulates histone deacetylases, promotes cell proliferation, and inhibits apoptosis. We hypothesized that NAMPT promotes pulmonary vascular remodeling and that inhibition of NAMPT could attenuate pulmonary hypertension. METHODS Plasma, mRNA, and protein levels of NAMPT were measured in the lungs and isolated pulmonary artery endothelial cells from patients with pulmonary arterial hypertension and in the lungs of rodent models of pulmonary hypertension. Nampt+/- mice were exposed to 10% hypoxia and room air for 4 weeks, and the preventive and therapeutic effects of NAMPT inhibition were tested in the monocrotaline and Sugen hypoxia models of pulmonary hypertension. The effects of NAMPT activity on proliferation, migration, apoptosis, and calcium signaling were tested in human pulmonary artery smooth muscle cells. RESULTS Plasma and mRNA and protein levels of NAMPT were increased in the lungs and isolated pulmonary artery endothelial cells from patients with pulmonary arterial hypertension, as well as in lungs of rodent models of pulmonary hypertension. Nampt+/- mice were protected from hypoxia-mediated pulmonary hypertension. NAMPT activity promoted human pulmonary artery smooth muscle cell proliferation via a paracrine effect. In addition, recombinant NAMPT stimulated human pulmonary artery smooth muscle cell proliferation via enhancement of store-operated calcium entry by enhancing expression of Orai2 and STIM2. Last, inhibition of NAMPT activity attenuated monocrotaline and Sugen hypoxia-induced pulmonary hypertension in rats. CONCLUSIONS Our data provide evidence that NAMPT plays a role in pulmonary vascular remodeling and that its inhibition could be a potential therapeutic target for pulmonary arterial hypertension.

Abstract
Schistosomiasis is the most common parasitic disease associated with pulmonary arterial hypertension (PAH). It induces remodeling via complex inflammatory processes produced by the parasite eggs. Changes in the pulmonary vasculature after Schistosoma infection are common, but may not always be associated with a clinical manifestation of PAH. Those patients who presented with PAH show clinical signs and symptoms that are not distinguishable from other forms of PAH.

BMPRII influences the response of pulmonary microvascular endothelial cells to inflammatory mediators. Pflugers Arch 2016; 468:1969-1983. [PMID: 27816994 DOI: 10.1007/s00424-016-1899-1] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2016] [Revised: 10/13/2016] [Accepted: 10/24/2016] [Indexed: 10/20/2022]
Abstract
Mutations in the bone morphogenetic protein receptor (BMPR2) gene have been observed in 70 % of patients with heritable pulmonary arterial hypertension (HPAH) and in 11-40 % with idiopathic PAH (IPAH). However, carriers of a BMPR2 mutation have only 20 % risk of developing PAH. Since inflammatory mediators are increased and predict survival in PAH, they could act as a second hit inducing the development of pulmonary hypertension in BMPR2 mutation carriers. Our specific aim was to determine whether inflammatory mediators could contribute to pulmonary vascular cell dysfunction in PAH patients with and without a BMPR2 mutation. Pulmonary microvascular endothelial cells (PMEC) and arterial smooth muscle cells (PASMC) were isolated from lung parenchyma of transplanted PAH patients, carriers of a BMPR2 mutation or not, and from lobectomy patients or lung donors. The effects of CRP and TNFα on mitogenic activity, adhesiveness capacity, and expression of adhesion molecules were investigated in PMECs and PASMCs. PMECs from BMPR2 mutation carriers induced an increase in PASMC mitogenic activity; moreover, endothelin-1 secretion by PMECs from carriers was higher than by PMECs from non-carriers. Recruitment of monocytes by PMECs isolated from carriers was higher compared to PMECs from non-carriers and from controls, with an elevated ICAM-1 expression. CRP increased adhesion of monocytes to PMECs in carriers and non-carriers, and TNFα only in carriers. PMEC from BMPR2 mutation carriers have enhanced adhesiveness for monocytes in response to inflammatory mediators, suggesting that BMPR2 mutation could generate susceptibility to an inflammatory insult in PAH.

Abstract
PURPOSE OF REVIEW Pulmonary arterial hypertension (PAH) is a rare disease with poor prognosis and no therapeutics. PAH is characterized by severe remodeling of precapillary pulmonary arteries, leading to increased vascular resistance, pulmonary hypertension compensatory right ventricular hypertrophy, then heart failure and death. PAH pathogenesis shares similarities with carcinogenesis such as excessive cell proliferation, apoptosis resistance, metabolic shifts, or phenotypic transition. Although PAH is not a cancer, comparison of analogous mechanisms between PAH and cancer led to the concept of a cancer-like disease to emerge. MicroRNAs (miRNAs) are small noncoding RNAs involved in the regulation of posttranscriptional gene expression. miRNA dysregulations have been reported as promoter of the development of various diseases including cancers. RECENT FINDINGS Recent studies revealed that miRNA dysregulations also occur in PAH pathogenesis. In PAH, different miRNAs have been implicated to be the main features of PAH pathophysiology (in pulmonary inflammation, vascular remodeling, angiogenesis, and right heart hypertrophy). SUMMARY The review summarizes the implication of miRNA dysregulation in PAH development and discusses the similarities and differences with those observed in cancers.

Abstract
Pulmonary hypertension (PH) is defined by a mean pulmonary arterial pressure over 25 mmHg at rest and is diagnosed by right heart catheterization. Among the different groups of PH, pulmonary arterial hypertension (PAH) is characterized by a progressive obstruction of distal pulmonary arteries, related to endothelial cell dysfunction and vascular cell proliferation, which leads to an increased pulmonary vascular resistance, right ventricular hypertrophy, and right heart failure. Although the primary trigger of PAH remains unknown, oxidative stress and inflammation have been shown to play a key role in the development and progression of vascular remodeling. These factors are known to increase DNA damage that might favor the emergence of the proliferative and apoptosis-resistant phenotype observed in PAH vascular cells. High levels of DNA damage were reported to occur in PAH lungs and remodeled arteries as well as in animal models of PH. Moreover, recent studies have demonstrated that impaired DNA-response mechanisms may lead to an increased mutagen sensitivity in PAH patients. Finally, PAH was linked with decreased breast cancer 1 protein (BRCA1) and DNA topoisomerase 2-binding protein 1 (TopBP1) expression, both involved in maintaining genome integrity. This review aims to provide an overview of recent evidence of DNA damage and DNA repair deficiency and their implication in PAH pathogenesis.

The prognostic impact of thyroid function in pulmonary hypertension. J Heart Lung Transplant 2016; 35:1427-1434. [PMID: 27373820 DOI: 10.1016/j.healun.2016.05.022] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2016] [Revised: 03/29/2016] [Accepted: 05/30/2016] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Thyroid disease is common in patients with pulmonary hypertension (PH), but its effect on long-term survival remains unknown. We examined the prognostic significance of thyroid hormone levels of free triiodothyronine (fT3) and free thyroxine and thyroid-stimulating hormone (TSH), and thyroid hormone replacement (THR) therapy in PH. METHODS We conducted a retrospective analysis of 1,756 patients enrolled in the Giessen PH Registry in 1999 to 2013 with baseline thyroid function data; of these, 355, 533, 498, and 370 had pulmonary arterial hypertension (PAH); including 192 with idiopathic PAH (iPAH), PH due to left heart disease, PH due to lung diseases, and chronic thromboembolic PH (CTEPH), respectively. Thyroid function parameters associated with mortality were identified using Cox regression and Kaplan-Meier analyses. RESULTS Transplant-free survival at 1, 3, and 5 years was 86.7%, 65.6%, and 53.0%, respectively. Absence of THR therapy was an independent predictor of death in iPAH (multivariate hazard ratio [HR], 2.50; 95% confidence interval [CI], 1.06-5.75). In patients without THR therapy, TSH levels in the lowest and highest quartiles (compared with the middle 2 quartiles) independently predicted death in iPAH (HR, 1.98; 95% CI, 1.07-3.67), whereas reduced fT3 levels were independently associated with increased death in PAH (HR, 8.30; 95% CI, 2.50-25.00) and CTEPH (HR, 1.79; 95% CI, 1.14-4.20). CONCLUSIONS Thyroid hormone levels and THR therapy are prognostic factors in iPAH, PAH, and CTEPH. Prospective studies are warranted to verify the prognostic significance of thyroid function and the effect of THR therapy in PH.

(7R,8S)-Dehydrodiconiferyl Alcohol Suppresses Lipopolysaccharide-Induced Inflammatory Responses in BV2 Microglia by Inhibiting MAPK Signaling. Neurochem Res 2016; 41:1570-7.

Abstract
(7R,8S)-Dehydrodiconiferyl alcohol (DDA), a lignan isolated from the dried stems of Clematis armandii, has been found to exert potential anti-inflammatory activity in vitro. In the present study, we investigated the effects and possible mechanisms of DDA on lipopolysaccharide (LPS)-mediated inflammatory response in murine BV2 microglia. Our results revealed that non-toxic concentrations (6.25-25 μM) of DDA markedly suppressed LPS-induced production of nitric oxide, expression of inducible nitric oxide synthase and cyclooxygenase-2, and release of inflammatory factors, including tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in a concentration dependent manner. In addition, DDA time- and concentration-dependently attenuated LPS-induced phosphorylation of c-Jun N-terminal kinase 1/2 (JNK), but not protein kinase B, p38, or extracellular signal-regulated kinase 1/2. Moreover, DDA significantly suppress LPS-mediated nuclear factor-κB (NF-κB) activation by inhibiting phosphorylation and nuclear translocation of NF-κB p65. Collectively, our results demonstrated that DDA inhibited LPS-stimulated inflammatory response in BV2 cell, at least in part, through inhibition of NF-κB activation and modulation of JNK signaling.

Abstract
BACKGROUND Mutations in the KCNK3 gene have been identified in some patients suffering from heritable pulmonary arterial hypertension (PAH). KCNK3 encodes an outward rectifier K(+) channel, and each identified mutation leads to a loss of function. However, the pathophysiological role of potassium channel subfamily K member 3 (KCNK3) in PAH is unclear. We hypothesized that loss of function of KCNK3 is a hallmark of idiopathic and heritable PAH and contributes to dysfunction of pulmonary artery smooth muscle cells and pulmonary artery endothelial cells, leading to pulmonary artery remodeling: consequently, restoring KCNK3 function could alleviate experimental pulmonary hypertension (PH). METHODS AND RESULTS We demonstrated that KCNK3 expression and function were reduced in human PAH and in monocrotaline-induced PH in rats. Using a patch-clamp technique in freshly isolated (not cultured) pulmonary artery smooth muscle cells and pulmonary artery endothelial cells, we found that KCNK3 current decreased progressively during the development of monocrotaline-induced PH and correlated with plasma-membrane depolarization. We demonstrated that KCNK3 modulated pulmonary arterial tone. Long-term inhibition of KCNK3 in rats induced distal neomuscularization and early hemodynamic signs of PH, which were related to exaggerated proliferation of pulmonary artery endothelial cells, pulmonary artery smooth muscle cell, adventitial fibroblasts, and pulmonary and systemic inflammation. Lastly, in vivo pharmacological activation of KCNK3 significantly reversed monocrotaline-induced PH in rats. CONCLUSIONS In PAH and experimental PH, KCNK3 expression and activity are strongly reduced in pulmonary artery smooth muscle cells and endothelial cells. KCNK3 inhibition promoted increased proliferation, vasoconstriction, and inflammation. In vivo pharmacological activation of KCNK3 alleviated monocrotaline-induced PH, thus demonstrating that loss of KCNK3 is a key event in PAH pathogenesis and thus could be therapeutically targeted.

Abstract
Pulmonary arterial hypertension (PAH) is a rare, complex and multifactorial disease in which pulmonary vascular remodeling plays a major role ending in right heart failure and death. Current specific therapies of PAH that mainly target the vasoconstriction/vasodilatation imbalance are not curative. Bi-pulmonary transplantation remains the only option in patients resistant to current therapies. It is thus crucial to identify novel vascular anti-remodeling therapeutic targets. This remodeling displays several properties of cancer cells, especially overproliferation and apoptosis resistance of pulmonary vascular cells, hallmarks of cancer related to the metabolic shift known as the "Warburg effect". The latter is characterized by a shift of ATP production, from oxidative phosphorylation to low rate aerobic glycolysis. In compensation, the cancer cells exhibit exacerbated glutaminolysis thus resulting in glutamine addiction, necessary to their overproliferation. Glutamine intake results in glutamate production, a molecule at the crossroads of energy metabolism and cancer cell communication, thus contributing to cell proliferation. Accordingly, therapeutic strategies targeting glutamate production, its release into the extracellular space and its membrane receptors have been suggested to treat different types of cancers, not only in the central nervous system but also in the periphery. We propose that similar strategies targeting glutamatergic signaling may be considered in PAH, especially as they could affect not only the vascular remodeling but also the right heart hypertrophy known to involve the glutaminolysis pathway. Ongoing studies aim to characterize the involvement of the glutamate pathway and its receptors in vascular remodeling, and the therapeutic potential of specific molecules targeting this pathway.

Abstract
Nitric oxide (NO) is a critical signaling molecule in the pulmonary vasculature. NO activates soluble guanylate cyclase (sGC) resulting in the synthesis of cyclic guanosine monophosphate (cGMP) - a key mediator of pulmonary artery vasodilatation that may also inhibit smooth muscle proliferation and platelet aggregation. Pulmonary hypertension, a serious, progressive and often fatal disease is characterized by NO-sGC-sGMP pathway dysregulation. Riociguat is a member of a novel therapeutic class known as soluble guanylate stimulators. Riociguat has a dual mode of action, acting in synergy with endogenous NO and also directly stimulating sGC independently of NO availability. Phase 3 randomized control trials have demonstrated that riociguat improves clinical, physiologic and hemodynamic parameters in patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension. In this review we will discuss the pharmacologic properties of riociguat and its appropriate implementation into clinical practice.

Abstract
Pulmonary hypertension (PH) is a fatal syndrome that arises from a multifactorial and complex background, is characterized by increased pulmonary vascular resistance and right heart afterload, and often leads to cor pulmonale. Over the past decades, remarkable progress has been made in reducing patient symptoms and delaying the progression of the disease. Unfortunately, PH remains a disease with no cure. The substantial heterogeneity of PH continues to be a major limitation to the development of newer and more efficacious therapies. New advances in our understanding of the biological pathways leading to such a complex pathogenesis will require the identification of the important proteins and protein networks that differ between a healthy lung (or right ventricle) and a remodeled lung in an individual with PH. In this article, we present the case for the increased use of proteomics--the study of proteins and protein networks--as a discovery tool for key proteins and protein networks operational in the PH lung. We review recent applications of proteomics in PH, and summarize the biological pathways identified. Finally, we attempt to presage what the future will bring with regard to proteomics in PH and offer our perspectives on the prospects of developing personalized proteomics and custom-tailored therapies.

Abstract
Pulmonary arterial hypertension (PAH) is a devastating cardiopulmonary disorder with various origins. All forms of PAH share a common pulmonary arteriopathy characterised by vasoconstriction, remodelling of the pre-capillary pulmonary vessel wall, and in situ thrombosis. Although the pathogenesis of PAH is recognised as a complex and multifactorial process, there is growing evidence that potassium channels dysfunction in pulmonary artery smooth muscle cells is a hallmark of PAH. Besides regulating many physiological functions, reduced potassium channels expression and/or activity have significant effects on PAH establishment and progression. This review describes the molecular mechanisms and physiological consequences of potassium channel modulation. Special emphasis is placed on KCNA5 (Kv1.5) and KCNK3 (TASK1), which are considered to play a central role in determining pulmonary vascular tone and may represent attractive therapeutic targets in the treatment of PAH.

Abstract
Rationale:
Pulmonary arterial hypertension (PAH) is a vasculopathy characterized by enhanced pulmonary artery (PA) smooth muscle cell (PASMC) proliferation and suppressed apoptosis. Decreased expression of microRNA-204 has been associated to this phenotype. By a still elusive mechanism, microRNA-204 downregulation promotes the expression of oncogenes, including nuclear factor of activated T cells, B-cell lymphoma 2, and Survivin. In cancer, increased expression of the epigenetic reader bromodomain-containing protein 4 (BRD4) sustains cell survival and proliferation. Interestingly, BRD4 is a predicted target of microRNA-204 and has binding sites on the nuclear factor of activated T cells promoter region.
Objective:
To investigate the role of BRD4 in PAH pathogenesis.
Methods and Results:
BRD4 is upregulated in lungs, distal PAs, and PASMCs of patients with PAH compared with controls. With mechanistic in vitro experiments, we demonstrated that BRD4 expression in PAH is microRNA-204 dependent. We further studied the molecular downstream targets of BRD4 by inhibiting its activity in PAH–PASMCs using a clinically available inhibitor JQ1. JQ1 treatment in PAH–PASMCs increased p21 expression, thus triggering cell cycle arrest. Furthermore, BRD4 inhibition, by JQ1 or siBRD4, decreased the expression of 3 major oncogenes, which are overexpressed in PAH: nuclear factor of activated T cells, B-cell lymphoma 2, and Survivin. Blocking this oncogenic signature led to decreased PAH-PASMC proliferation and increased apoptosis in a BRD4-dependent manner. Indeed, pharmacological JQ1 or molecular (siRNA) inhibition of BRD4 reversed this pathological phenotype in addition to restoring mitochondrial membrane potential and to increasing cells spare respiratory capacity. Moreover, BRD4 inhibition in vivo reversed established PAH in the Sugen/hypoxia rat model.
Conclusions:
BRD4 plays a key role in the pathological phenotype in PAH, which could offer new therapeutic perspectives for patients with PAH.

Abstract
BACKGROUND Inflammation may contribute to the pathobiology of pulmonary arterial hypertension (PAH). Deciphering the PAH fingerprint on the inflammation orchestrated by dendritic cells (DCs) and T cells, key driver and effector cells, respectively, of the immune system, may allow the identification of immunopathologic approaches to PAH management. METHODS Using flow cytometry, we performed immunophenotyping of monocyte-derived DCs (MoDCs) and circulating lymphocytes from patients with idiopathic PAH and control subjects. With the same technique, we performed cytokine profiling of both populations following stimulation, coculture, or both. We tested the immunomodulatory effects of a glucocorticoid (dexamethasone [Dex]) on this immunophenotype and cytokine profile. Using an epigenetic approach, we confirmed the immune polarization in blood DNA of patients with PAH. RESULTS The profile of membrane costimulatory molecules of PAH MoDCs was similar to that of control subjects. However, PAH MoDCs retained higher levels of the T-cell activating molecules CD86 and CD40 after Dex pretreatment than did control MoDCs. This was associated with an increased expression of IL-12p40 and a reduced migration toward chemokine (C-C motif) ligand 21. Moreover, both with and without Dex, PAH MoDCs induced a higher activation and proliferation of CD4+ T cells, associated with a reduced expression of IL-4 (T helper 2 response) and a higher expression of IL-17 (T helper 17 response). Purified PAH CD4+ T cells expressed a higher level of IL-17 after activation than did those of control subjects. Lastly, there was significant hypomethylation of the IL-17 promoter in the PAH blood DNA as compared with the control blood. CONCLUSIONS We have highlighted T helper 17 cell immune polarization in patients with PAH, as has been previously demonstrated in other chronic inflammatory and autoimmune conditions.
