Abstract
The first immune-activating changes within joint resident cells that lead to pathogenic leukocyte recruitment during articular inflammation remain largely unknown. In this study, we employ state-of-the-art confocal microscopy and image analysis in a systemic, whole-organ, and quantitative way to present evidence that synovial inflammation begins with the activation of lining macrophages. We show that lining, but not sublining macrophages phagocytose immune complexes containing the model antigen. Using the antigen-induced arthritis (AIA) model, we demonstrate that on recognition of antigen-antibody complexes, lining macrophages undergo significant activation, which is dependent on interferon regulatory factor 5 (IRF5), and produce chemokines, most notably CXCL1. Consequently, at the onset of inflammation, neutrophils are preferentially recruited in the vicinity of antigen-laden macrophages in the synovial lining niche. As inflammation progresses, neutrophils disperse across the whole synovium and form swarms in synovial sublining during resolution. Our study alters the paradigm of lining macrophages as immunosuppressive cells to important instigators of synovial inflammation.

[PMID: 31310649 PMCID: PMC7181722 DOI: 10.1093/jmcb/mjz077] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2019] [Revised: 05/31/2019] [Accepted: 06/18/2019] [Indexed: 12/30/2022] Open
Abstract
Although the adhesion molecules-mediated leukocyte adherence and infiltration into tissues is an important step of inflammation, the post-translational regulation of these proteins on the endothelial cells is poorly understood. Here, we report that TRIM65, an ubiquitin E3 ligase of tripartite protein family, selectively targets vascular cell adhesion molecule 1 (VCAM-1) and promotes its ubiquitination and degradation, by which it critically controls the duration and magnitude of sepsis-induced pulmonary inflammation. TRIM65 is constitutively expressed in human vascular endothelial cells. During TNFα-induced endothelial activation, the protein levels of TRIM65 and VCAM-1 are inversely correlated. Expression of wild-type TRIM65, but not expression of a TRIM65 mutant that lacks E3 ubiquitin ligase function in endothelial cells, promotes VCAM-1 ubiquitination and degradation, whereas small interference RNA-mediated knockdown of TRIM65 attenuates VCAM-1 protein degradation. Further experiments show that TRIM65 directly interacts with VCAM-1 protein and directs its polyubiquitination, by which TRIM65 controls monocyte adherence and infiltration into tissues during inflammation. Importantly, TRIM65-deficient mice are more sensitive to lipopolysaccharide-induced death, due to sustained and severe pulmonary inflammation. Taken together, our studies suggest that TRIM65-mediated degradation of VCAM-1 represents a potential mechanism that controls the duration and magnitude of inflammation.

Abstract
The endothelial cell adhesion molecule E-selectin is a key component of the bone marrow hematopoietic stem cell (HSC) vascular niche regulating balance between HSC self-renewal and commitment. We now report in contrast, E-selectin directly triggers signaling pathways that promote malignant cell survival and regeneration. Using acute myeloid leukemia (AML) mouse models, we show AML blasts release inflammatory mediators that upregulate endothelial niche E-selectin expression. Alterations in cell-surface glycosylation associated with oncogenesis enhances AML blast binding to E-selectin and enable promotion of pro-survival signaling through AKT/NF-κB pathways. In vivo AML blasts with highest E-selectin binding potential are 12-fold more likely to survive chemotherapy and main contributors to disease relapse. Absence (in Sele−/− hosts) or therapeutic blockade of E-selectin using small molecule mimetic GMI-1271/Uproleselan effectively inhibits this niche-mediated pro-survival signaling, dampens AML blast regeneration, and strongly synergizes with chemotherapy, doubling the duration of mouse survival over chemotherapy alone, whilst protecting endogenous HSC. The cell adhesion molecule E-selectin regulates haematopoietic stem cell self-renewal in the bone marrow vascular niche. Here, the authors show E-selectin adhesion directly induces survival signaling in acute myeloid leukaemia and therapeutic inhibition improves chemotherapy outcomes in mice.

Abstract
BACKGROUND The issue whether anaesthesia has an impact on the prognosis of carcinoma has been widely discussed and remains debated. Ropivacaine has been widely used in perioperative period as a long acting local anesthetic. An early event during recurrence or metastasis of carcinoma is the adhesion of circulating tumour cells (CTCs) to endothelial cells (ECs) through binding adhesion molecules that are up-regulated on inflamed endothelium during the perioperative period or other periods. This study was to explore the impact of ropivacaine on the adhesion of tumour cells, providing evidences of its influence on the prognosis of carcinoma. MATERIALS AND METHODS Human umbilical vein endothelial cells (HUVECs) were pre-treated with ropivacaine (10-7-10-5 M; 30 min) prior to treatment with tumour necrosis factor alpha (TNFα) (10 ng ml-1; 1, 4 and 8 h). Intercellular adhesion molecule-1 (ICAM-1), endothelial-selectin (CD62E) and vascular cell adhesion molecule-1 (VCAM-1) mRNA levels were detected via quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR). To clarify the underlying action mechanism, p65, p-p65, IκBα, p-IκBα, IKKα/β and p-IKKα/β protein levels were evaluated via western blotting. Cell viability and tumour cell adhesion assays were also assessed. RESULTS The clinically usage concentration of ropivacaine (10-6 M) produced a significant decrease in CD62E expression compared with that produced by TNFα only (p < 0.001). Moreover, adhesion assays showed that ropivacaine effectively inhibited the adhesion of hepatoma cells (p < 0.01), human colon cancer cells (p < 0.01) and human leukemic monocyte (p < 0.01). Western blot results showed that pre-treatment with ropivacaine inhibited the phosphorylation of p65 (p < 0.05), IκBα (p < 0.001) and IKKα/β (p < 0.01). CONCLUSIONS Ropivacaine decreased the adhesion of tumour cells. Ropivacaine modulated CD62E expression by inhibiting the activation of NF-κB. These results might provide new insight into the issue whether anaesthesia has an impact on the prognosis of carcinoma.

Abstract
Mannose receptor (CD206) and E-selectin are selectively expressed in M2-like tumor-associated macrophages (M2-TAMs) and activated endothelial cells of vessels surrounding tumor tissues. With the knowledge that D-mannose is the natural ligand of mannose receptors and L-fucose is the key calcium chelator for tumor-associated carbohydrate antigens (TACAs) binding to E-selectin, herein, we firstly reported D-mannose polyethylene glycol (PEG) conjugates (Man-PEG) and L-fucose PEG conjugates (Fuc-PEG) co-modified liposomal doxorubicin (DOX-MFPL) to improve tumor-targeting ability. The dual-ligand modified PEGylated liposomes (DOX-MFPL) were assessed by both in vitro and in vivo trials. Compared with the single-ligand D-mannose- or L-fucose-modified liposomes (DOX-MPL or DOX-FPL), DOX-MFPL achieved an increased distribution of DOX in tumor tissues. The antitumor study based on S180 tumor-bearing mice was conducted and the superior tumor inhibitory rate was shown with DOX-MFPL, probably owing to the superior tumor-targeting effect of DOX-MFPL and the modulation of the tumor microenvironment with the exhaustion of TAMs. In general, the dual-ligand drug delivery systems are expected to be promising in the development of specific and efficient methods for tumor treatment.

Abstract
The treatment of organ failure on patients requires the transplantation of functional organs, from donors. Over time, the methodology of transplantation was improved by the development of organ preservation solutions. The storage of organs in preservation solutions is followed by the ischemia of the organ, resulting in a shortage of oxygen and nutrients, which damage the tissues. When the organ is ready for the transplantation, the reperfusion of the organ induces an increase of the oxidative stress, endoplasmic reticulum stress, and inflammation which causes tissue damage, resulting in a decrease of the transplantation success. However, the addition of proteasome inhibitor in the preservation solution alleviated the injuries due to the ischemia-reperfusion process. The proteasome is a protein structure involved in the regulation the inflammation and the clearance of damaged proteins. The goal of this review is to summarize the role of the proteasome and pharmacological compounds that regulate the proteasome in protecting the organs from the ischemia-reperfusion injury.

Abstract
Activation of the blood vessel endothelium is a critical step during inflammation. Endothelial cells stimulated by pro-inflammatory cytokines play an essential part in the adhesion and extravasation of circulating leukocytes into inflamed tissues. The endothelial egfl7 gene (VE-statin) represses endothelial cell activation in tumors, and prior observations suggested that it could also participate in the regulation of endothelial cell activation during inflammation. We show here that Egfl7 expression is strongly repressed in mouse lung endothelial cells during LPS- and TNFα-induced inflammation in vivo LPS have a limited effect on Egfl7 expression by endothelial cells in vitro, whereas the pro-inflammatory cytokine TNFα strongly represses Egfl7 expression in endothelial cells. TNFα regulates the egfl7 gene promoter through regions located between -7585 and -5550 bp ahead of the main transcription start site and via an NF-κB-dependent mechanism. Conversely, Egfl7 regulates the response of endothelial cells to TNFα by restraining the induced expression of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin, resulting in a decreased adhesion of leukocytes onto endothelial cells stimulated by TNFα. Egfl7 regulates the expression of these adhesion molecules through the NF-κB and MEK/Erk pathways, in particular by preventing the proteasome-mediated degradation of IkBα both in non-activated endothelial cells and during activation. Egfl7 is thus an endogenous and constitutive repressor of blood vessel endothelial cell activation in normal and inflammatory conditions and participates in a loop of regulation of activation of these cells by pro-inflammatory cytokines.

Abstract
AIM The aryl hydrocarbon receptor (AhR), a ligand-inducible transcription factor mediating toxic effects of dioxins and uremic toxins, has recently emerged as a pathophysiological regulator of immune-inflammatory conditions. Indoxyl sulfate, a uremic toxin, is associated with cardiovascular disease in patients with chronic kidney disease and has been shown to be a ligand for AhR. The aim of this study was to investigate the potential role of AhR in indoxyl sulfate-induced leukocyte-endothelial interactions. METHODS Endothelial cell-specific AhR knockout (eAhR KO) mice were produced by crossing AhR floxed mice with Tie2 Cre mice. Indoxyl sulfate was administered for 2 weeks, followed by injection of TNF-α. Leukocyte recruitment to the femoral artery was assessed by intravital microscopy. Vascular endothelial cells were transfected with siRNA specific to AhR (siAhR) and treated with indoxyl sulfate, followed by stimulation with TNF-α. RESULTS Indoxyl sulfate dramatically enhanced TNF-α-induced leukocyte recruitment to the vascular wall in control animals but not in eAhR KO mice. In endothelial cells, siAhR significantly reduced indoxyl sulfate-enhanced leukocyte adhesion as well as E-selectin expression, whereas the activation of JNK and nuclear factor-κB was not affected. A luciferase assay revealed that the region between -153 and -146 bps in the E-selectin promoter was responsible for indoxyl sulfate activity via AhR. Mutational analysis of this region revealed that activator protein-1 (AP-1) is responsible for indoxyl sulfate-triggered E-selectin expression via AhR. CONCLUSION AhR mediates indoxyl sulfate-enhanced leukocyte-endothelial interactions through AP-1 transcriptional activity, which may constitute a new mechanism of vascular inflammation in patients with renal disease.

Abstract
Vascular injury is a serious complication of sepsis due to the gram‐negative bacterium Neisseria meningitidis. One of the critical early steps in initiating this injury is via the interaction of leucocytes, particularly neutrophils, with adhesion molecules expressed on inflamed endothelium. We have previously demonstrated that both lipopolysaccharide (LPS) and non‐LPS components of meningococci can induce very high levels of expression of the vascular endothelial cell adhesion molecule E‐selectin, which is critical for early tethering and capture of neutrophils onto endothelium under flow. Using an LPS‐deficient strain of meningococcus, we showed that very high levels of expression can be induced in primary endothelial cells, even in the context of weak activation of the major host signal transduction factor [nuclear factor‐κB (NF‐κB)]. In this study, we show that the particular propensity for N. meningitidis to induce high levels of expression is regulated at a transcriptional level, and demonstrate a significant role for phosphorylation of the ATF2 transcription factor, likely via mitogen‐activated protein (MAP) kinases, on the activity of the E‐selectin promoter. Furthermore, inhibition of E‐selectin expression in response to the lpxA− strain by a p38 inhibitor indicates a significant role of a p38‐dependent MAPK signalling pathway in ATF2 activation. Collectively, these data highlight the role that LPS and other bacterial components have in modulating endothelial function and their involvement in the pathogenesis of meningococcal sepsis. Better understanding of these multiple mechanisms induced by complex stimuli such as bacteria, and the specific inflammatory pathways they activate, may lead to improved, focused interventions in both meningococcal and potentially bacterial sepsis more generally.

Characterization of a novel endothelial biosensor assay reveals increased cumulative serum inflammatory potential in stabilized coronary artery disease patients. J Transl Med 2015; 13:99. [PMID: 25890092 PMCID: PMC4376347 DOI: 10.1186/s12967-015-0457-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2014] [Accepted: 03/10/2015] [Indexed: 11/10/2022] Open
Abstract
Background Vascular disease is promoted by systemic inflammation that can arise from sites distal to the affected vessels. We sought to characterize the net inflammatory potential of serum from patients with coronary artery disease (CAD) using cultured endothelial cells as a cumulative biosensor. Methods and results Serum samples from CAD patients (N = 45) and healthy control subjects (N = 48) were incubated with primary human coronary artery endothelial cells at a 1:10 dilution for 4 h, followed by isolation of the cellular RNA. Alteration of inflammation-responsive elements (adhesion molecules and cytokines) was assessed by gene expression. Specific indicators included intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and interleukin-8 (IL-8). Additionally, the cytokine levels in serum samples from all subjects were quantified. Serum from CAD subjects induced greater endothelial ICAM-1, VCAM-1, and IL-8 expression compared to healthy control serum (p < 0.001 for each analysis). The three indicators of inflammatory potential (ICAM-1, VCAM-1, and IL-8 mRNA) trended independently of each other and also of serum inflammatory biomarkers. IL-8 expression correlated negatively with serum HDL levels but positively correlated with VLDL, plasminogen activator inhibitor-1 and C-reactive protein. Interestingly, serum levels of cytokines in CAD patients were not statistically different from healthy control subjects. A year of follow-up in a sub-group of CAD subjects revealed relatively stable measures. Conclusions As yet unidentified circulating factors in the serum of CAD patients appear to activate endothelial cells, leading to upregulation of adhesion molecules and chemokines. This cumulative assay performed well in terms of discriminating patients with CAD compared to healthy subjects, with greater range and specificity than specific inflammatory markers.

CD40 ligand induces expression of vascular cell adhesion molecule 1 and E-selectin in orbital fibroblasts from patients with Graves' orbitopathy. Graefes Arch Clin Exp Ophthalmol 2015; 253:573-82. [PMID: 25576172 DOI: 10.1007/s00417-014-2902-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2014] [Revised: 12/03/2014] [Accepted: 12/15/2014] [Indexed: 11/30/2022] Open
Abstract
PURPOSE The aim of this study was to detect the effect of the CD40 ligand (CD40L) on the expression of vascular cell adhesion molecule 1 (VCAM-1) and E-Selectin in orbital fibroblasts (OFs) from patients with Graves' orbitopathy (GO), as well as the signaling pathways involved in this effect. METHODS OFs were isolated from orbital tissues obtained from patients with severe GO who were undergoing orbital decompression surgery. VCAM-1 and E-selectin RNA and protein expression levels were quantified in OFs stimulated with soluble CD40L (sCD40L). RNA and protein quantification was performed with real-time polymerase chain reaction (PCR) and western blot analysis. Cytoplasmic and nuclear fractions were isolated in order to detect the nuclear translocation of nuclear factor-κB (NF-κB). Signaling pathway inhibitors were applied to determine the pathways involved. RESULTS Compared to unstimulated OFs, the mRNA and protein levels of VCAM-1 and E-selectin in OFs incubated with sCD40L were significantly increased. This was observed in dose- and time-course experiments, and the inductive effects of sCD40L were much weaker in OFs from healthy donors. At the same time, we observed that CD40L induced nuclear translocation of NF-κB, also in a dose- and time-dependent manner. The up-regulation of VCAM-1 and E-selectin, as well as the NF-κB nuclear translocation induced by CD40L, was significantly attenuated by inhibitors targeting mitogen-activated protein kinases (MAPKs), phosphatidylinositol 3-kinase (PI3K), and NF-κB. CONCLUSIONS CD40L demonstrated the ability to up-regulate the expression of VCAM-1 and E-selectin at the pre-translational level in OFs from patients with GO. The MAPK and PI3K pathways and NF-κB may play important roles in CD40L-induced VCAM-1 and E-selectin expression.

Abstract
Background The metastasis of hematogenous cancer cells is associated with abnormal glycosylation such as sialyl lewis antigens. Although the hepatitis B virus X protein (HBx) plays important role in liver disease, the precise function of HBx on aberrant glycosylation for metastasis remains unclear. Methods The human hepatocellular carcinoma tissues, HBx transgenic mice and HBx-transfected cells were used to check the correlation of expressions between HBx and Sialyl lewis antigen for cancer metastasis. To investigate whether expression levels of glycosyltransferases induced in HBx-transfected cells are specifically associated with sialyl lewis A (SLA) synthesis, which enhances metastasis by interaction of liver cancer cells with endothelial cells, ShRNA and siRNAs targeting specific glycosyltransferases were used. Results HBx expression in liver cancer region of HCC is associated with the specific synthesis of SLA. Furthermore, the SLA was specifically induced both in liver tissues from HBx-transgenic mice and in in vitro HBx-transfected cells. HBx increased transcription levels and activities of α2-3 sialyltransferases (ST3Gal III), α1-3/4 fucosyltransferases III and VII (FUT III and VII) genes, which were specific for SLA synthesis, allowing dramatic cell-cell adhesion for metastatic potential. Interestingly, HBx specifically induced expression of N-acetylglucosamine-β1-3 galactosyltransferase V (β1-3GalT 5) gene associated with the initial synthesis of sialyl lewis A, but not β1-4GalT I. The β1-3GalT 5 shRNA suppressed SLA expression by HBx, blocking the adhesion of HBx-transfected cells to the endothelial cells. Moreover, β1-3GalT 5 silencing suppressed lung metastasis of HBx-transfected cells in in vivo lung metastasis system. Conclusion HBx targets the specific glycosyltransferases for the SLA synthesis and this process regulates hematogenous cancer cell adhesion to endothelial cells for cancer metastasis.

Abstract
Islet cell transplantation is a promising beta cell replacement therapy for patients with brittle type 1 diabetes as well as refractory chronic pancreatitis. Despite the vast advancements made in this field, challenges still remain in achieving high frequency and long-term successful transplant outcomes. Here we review recent advances in understanding the role of inflammation in islet transplantation and development of strategies to prevent damage to islets from inflammation. The inflammatory response associated with islets has been recognized as the primary cause of early damage to islets and graft loss after transplantation. Details on cell signaling pathways in islets triggered by cytokines and harmful inflammatory events during pancreas procurement, pancreas preservation, islet isolation, and islet infusion are presented. Robust control of pre- and peritransplant islet inflammation could improve posttransplant islet survival and in turn enhance the benefits of islet cell transplantation for patients who are insulin dependent. We discuss several potent anti-inflammatory strategies that show promise for improving islet engraftment. Further understanding of molecular mechanisms involved in the inflammatory response will provide the basis for developing potent therapeutic strategies for enhancing the quality and success of islet transplantation.

Abstract
EC activation and dysfunction have been linked to a variety of vascular inflammatory disease states. The function of microRNAs (miRNAs) in vascular EC activation and inflammation remains poorly understood. Herein, we report that microRNA-181b (miR-181b) serves as a potent regulator of downstream NF-κB signaling in the vascular endothelium by targeting importin-α3, a protein that is required for nuclear translocation of NF-κB. Overexpression of miR-181b inhibited importin-α3 expression and an enriched set of NF-κB-responsive genes such as adhesion molecules VCAM-1 and E-selectin in ECs in vitro and in vivo. In addition, treatment of mice with proinflammatory stimuli reduced miR-181b expression. Rescue of miR-181b levels by systemic administration of miR-181b "mimics" reduced downstream NF-κB signaling and leukocyte influx in the vascular endothelium and decreased lung injury and mortality in endotoxemic mice. In contrast, miR-181b inhibition exacerbated endotoxin-induced NF-κB activity, leukocyte influx, and lung injury. Finally, we observed that critically ill patients with sepsis had reduced levels of miR-181b compared with control intensive care unit (ICU) subjects. Collectively, these findings demonstrate that miR-181b regulates NF-κB-mediated EC activation and vascular inflammation in response to proinflammatory stimuli and that rescue of miR-181b expression could provide a new target for antiinflammatory therapy and critical illness.

Abstract
E-selectin, also known as CD62E, is a cell adhesion molecule expressed on endothelial cells activated by cytokines. Like other selectins, it plays an important part in inflammation and in the adhesion of metastatic cancer cells to the endothelium. E-selectin recognizes and binds to sialylated carbohydrates present on the surface proteins of certain leukocytes. E-selectin has been chosen as a target for several therapeutic and medical imaging applications, based on its expression in the vicinity of inflammation, infection or cancer. These systems for drug delivery and molecular imaging include immunoconjugates, liposomes, nanoparticles, and microparticles prepared from a wide range of starting materials including lipids, synthetic polymers, polypeptides and organo-metallic structures. After a brief introduction presenting the selectin family and their implication in physiology and pathology, this review focuses on the formulation of these new delivery systems targeting E-selectin at a molecular level.

Abstract
P120 catenin (p120ctn) is an adherens junction protein recognized to regulate barrier function, but emerging evidence indicates that p120ctn may also exert control on other cellular functions such as transcriptional suppression of genes. We investigated the hypothesis that loss of p120ctn in human endothelial cells activates transcription of pro-inflammatory adhesion molecules. For study, siRNA targeted to p120ctn was transfected into brain microvascular (HBMECs) or pulmonary artery endothelial cells (HPAECs) for 24-120h, which depleted 50-80% of endogenous p120ctn. This loss of p120ctn resulted in increased promoter reporter activity of transcription factors, NFκB, AP-1, and Kaiso, as well as of target genes, MMP-1 and ICAM-1. Real-time RT-PCR analysis indicated that the mRNA for ICAM-1, VCAM-1, and E- and P-selectins were all upregulated during the period of 24-120h of p120ctn depletion, although the time-course and extent of the expression profiles differed. The upregulated mRNA of adhesion molecules corresponded with increased PMN adhesion to the EC surface and elevated ICAM-1 protein expression. We further explored the role of ERK1/2 as a potential signaling mechanism responsible for regulation of transcriptional activities by p120ctn. Results indicated that loss of p120ctn increased phosphorylated ERK1/2, and a MEK1 inhibitor (PD98059) prevented NFκB nuclear translocation. This implicates ERK1/2 in signaling the NFκB activation induced by p120ctn loss. The findings provide strong evidence that deficiency in p120ctn expression in endothelial cells is a potent stimulus for transcriptional upregulation of multiple adhesion molecules. We conclude that p120ctn functions to suppress transcription, which is an important and novel regulation in vascular endothelium.

Abstract
BACKGROUND E-selectin is an attractive endothelial cell surface marker in inflammation and cancer. PURPOSE We sought to investigate retargeting of adenovirus via E-selectin as a viable pathway of infection in tumor necrosis factor-α (TNF-α)-activated human umbilical vein endothelial cells (HUVECs). METHODS E1, E3-deleted Ad5 expressing cytomegalovirus immediate-early (CMV IE) promoter-driven luciferase (Adluc) was coated with an amino-reactive multivalent hydrophilic polymer based on poly [N-(2-hydroxypropyl) methacrylamide] to generate pHPMA-adenovirus (pcAdluc). This was then retargeted by covalent attachment of a mouse antihuman E-selectin monoclonal antibody (MHES mAb), purified from the H18/7 hybridoma cell line (MHESpcAdluc). RESULTS MHESpcAdluc was efficiently taken up into HUVECs, generating a high level of transduction in TNF-α-treated E-selectin positive cells but not in untreated receptor-negative cells. Specific retargeting of MHESpcAdluc was demonstrated through reduced transduction of stimulated HUVEC when incubated in the presence of free E-selectin antibodies. DISCUSSION AND CONCLUSION Our results suggest that E-selectin could be a valuable target for gene transfer strategies internalizing polymer-coated modified adenovirus particles through a viable receptor-mediated endocytosis pathway, generating adequate levels of transgene expression per virus genome copy without compromising the specific activity of the parental virus.

Abstract
E-selectin is an early response adhesion molecule expressed on the surface of endothelial cells during inflammatory responses. We examined the effects of two pentacyclic triterpenoid acids, ursolic acid (UA) and oleanolic acid (OA), on the expression of E-selectin by cultured human umbilical vein endothelial cells (HUVECs). Treatment of the cells with UA or OA alone did not influence expression of E-selectin. Expression of E-selectin mRNA and surface antigen by HUVECs was induced by treatment with tumor necrosis factor-α (TNF-α) in a dose- and time-dependent manner. TNF-α-induced up-regulation of E-selectin was abrogated by pre-treatment of the cells with UA or OA which decreased expression of E-selectin mRNA. The repression of E-selectin mRNA expression caused by the pentacyclic triterpenoid acids paralleled the inhibition of NF-κB activation and nuclear translocation, as evaluated by electrophoretic mobility shift assays, although the degree of repression by UA was approximately two times more effective than that of OA. The results suggest that UA and OA suppress the inflammatory cytokine-induced expression of E-selectin in endothelial cells by decreasing E-selectin transcription via inhibition of NF-κB activation. Thus, UA and OA function as anti-inflammatory agents. The differences in the inhibitory efficacy between UA and OA may be due to conformational differences in ring-E of the two pentacyclic triterpenoid acids.

Abstract
Inflammation drives atherosclerosis. Both immune and resident vascular cell types are involved in the development of atherosclerotic lesions. The phenotype and function of these cells are key in determining the development of lesions. Toll-like receptors are the most characterised innate immune receptors and are responsible for the recognition of exogenous conserved motifs on pathogens, and, potentially, some endogenous molecules. Both endogenous and exogenous TLR agonists may be present in atherosclerotic plaques. Engagement of toll-like receptors on immune and resident vascular cells can affect atherogenesis as signalling downstream of these receptors can elicit proinflammatory cytokine release, lipid uptake, and foam cell formation and activate cells of the adaptive immune system. In this paper, we will describe the expression of TLRs on immune and resident vascular cells, highlight the TLR ligands that may act through TLRs on these cells, and discuss the consequences of TLR activation in atherosclerosis.

[PMID: 18937981 DOI: 10.1016/j.jneuroim.2008.09.006] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2008] [Revised: 09/03/2008] [Accepted: 09/04/2008] [Indexed: 01/05/2023]
Abstract
OBJECTIVE To study the effect of mucosal toleration to E-selectin on cerebral ischemia-reperfusion injury in rats and associated mechanisms. METHODS Rats were exposed to intranasal administration of E-selectin or PBS every other day for 10 days (single-tolerization group) or on two tolerization schedules separated by 11 days (booster-tolerization group). Control group received middle cerebral artery occlusion (MCAO) only. MCAO was performed 48 h after the last dose of E-selectin or PBS. After 2 h ischemia and 22 h reperfusion, the rats were killed. We examined the regional cerebral blood flow, neurological testing, frequencies of CD4+ T and CD8+ T lymphocytes in blood, plasma SOD activity, infarct volumes, and mRNA expressions of IL-10, TGF-beta(1), E-selectin, ICAM-1 and LFA-1 in the ischemic brain tissues. RESULTS There were 30.25% (P<0.05) decreases of infarction volumes in the E-selectin booster group accompanied by decreased neurological deficit scores compared with PBS group. Compared with PBS-treated rats, CD8-positive cells were significantly decreased (27.4%, P<0.05), CD4-positive cells tended to increase (P>0.05), SOD activity was obviously increased (P<0.05), mRNA levels of IL-10 were markedly increased (21.0%, P<0.05) and TGF-beta(1) showed an upward trend (6.2%, P>0.05), mRNA levels of E-selectin were prominently decreased (28.7%, P<0.01) and ICAM-1 and LFA-1 had downward trends (P>0.05) in E-selectin booster animals. CONCLUSIONS Mucosal tolerance to E-selectin after booster tolerization could relieve cerebral ischemia-reperfusion injury and induce ischemia tolerance in Wistar rats. The mechanisms may involve decreased frequencies of CD8+ T cells in blood, increased plasma SOD activity, heightened mRNA expression of IL-10 and lowered mRNA expression of E-selectin in the ischemic hemisphere.

Abstract
Particulate matter is associated with different human diseases affecting organs such as the respiratory and cardiovascular systems. Very small particles (nanoparticles) have been shown to be rapidly internalized into the body. Since the sites of internalization and the location of the detected particles are often far apart, a distribution via the blood stream must have occurred. Thus, endothelial cells, which line the inner surface of blood vessels, must have had direct contact with the particles. In this study we tested the effects of metallic nanoparticles (Co and Ni) on oxidative stress and pro-inflammatory response in human endothelial cells in vitro. Exposure to both nanoparticle types led to a concentration-dependent cytotoxic effect. However, the effects on oxidative stress and pro-inflammatory response differed dramatically. Due to the nanoparticle-induced effects, a comparison between metallic nanoparticle- and metal ion-treatment with the corresponding ions was made. Again, divergent effects of nanoparticles compared with the ions were observed, thus indicating differences in the signaling pathways induced by these compounds. These paradoxical responses to different metallic nanoparticles and ions demonstrate the complexity of nanoparticle-induced effects and suggest the need to design new strategies for nanoparticle toxicology.

Abstract
AIM Drug-eluting stents are widely used to prevent restenosis but are associated with late endothelial damage. To understand the basis for this effect, we have studied the consequences of a prolonged incubation with rapamycin on the viability and functions of endothelial cells. METHODS AND RESULTS Human umbilical vein or aorta endothelial cells were exposed to rapamycin in the absence or in the presence of tumour necrosis factor alpha (TNFalpha). After a 24 h-incubation, rapamycin (100 nM) caused a significant cell loss associated with the increase of both apoptosis and necrosis, as quantified by propidium iodide staining, caspase 3 activity, and lactate dehydrogenase release. Rapamycin also impaired cell mobility, as assessed by a wound test, and promoted the formation of actin stress fibres, as determined with confocal microscopy. Moreover, the inhibitor prolonged TNFalpha-dependent E-selectin induction, inhibited endothelial nitric oxide synthase expression at both mRNA (quantitative real-time polymerase chain reaction) and protein level (enzyme-linked immunosorbent assay and western blot), and lowered bioactive nitric oxide output (RFL-6 reporter cell assay). Under the conditions adopted, rapamycin inhibited both mammalian target-of-rapamycin complexes (mTORC1 and mTORC2), as indicated by the reduced amount of raptor and rictor bound to mTOR in immunoprecipitates and by the marked hypophosphorylation of protein S6 kinase I (p70S6K) and Akt, determined by western blotting. The selective inhibition of mTORC1 by AICAR did not affect endothelial viability. CONCLUSION A prolonged treatment with rapamycin impairs endothelial function and hinders cell viability. Endothelial damage seems dependent on mTORC2 inhibition.

Abstract
OBJECTIVE Radiosurgery for arteriovenous malformations is limited to small lesions and may take 3 years to produce total occlusion. It has recently been shown that coadministration of low-dose lipopolysaccharide (LPS) and soluble tissue factor (sTF) selectively induces thrombosis in murine tumor models, attributable perhaps to the prothrombotic phenotype of tumor vasculature. Radiosurgery may induce changes in endothelial prothrombotic molecules similar to those found in tumors. This study aimed to determine if a similar strategy could be used to stimulate thrombus formation in an animal arteriovenous malformation model. METHODS Seventeen rats underwent creation of a carotid-to-jugular anastomosis. Animals were intravenously injected with sTF, low-dose LPS, a combination of both, or placebo 24 hours after stereotactic irradiation of the anastomosis. Control animals received both agents after sham irradiation. RESULTS Coadministration of sTF and LPS led to the formation of thrombi in up to 69% of small vessels and 39% of medium-sized vessels within the target region. The irradiated vasculature demonstrated intermediate rates of thrombosis after treatment with either sTF or LPS alone as did vessels within the fistula in the control group. Logistic regression analysis demonstrated significant associations between development of thrombi and treatment with radiation, sTF, or LPS (P < 0.005). There was no evidence of systemic thrombus formation or toxicity in any group. CONCLUSION Treatment with sTF and LPS selectively induces thrombosis of irradiated vessels in a rat model of arteriovenous malformation. Stimulation of thrombosis may improve the efficacy of radiosurgery, increasing the treatable lesion size and reducing latency.

Abstract
To date, cancer is still the second most prevalent cause of death after cardiovascular diseases in the industrialized word, whereby the primary cause of cancer is not attributed to primary tumor formation, but rather to the growth of metastases at distant organ sites. For several years it was considered that the well-known phenomenon of organ-specific spreading of tumor cells is mostly a mechanical process either directed passively due to size constraints (mechanical trapping theory) or due to a fertile environment provided by the organ in which tumor cells can proliferate (seed and soil hypothesis). Both mechanisms strongly depend on the adhesive properties of tumor cells either to endothelial cells and/or cancer cells, which are facilitated by a variety of cell adhesion molecules including carbohydrates and integrins. Within the past years it became evident that the organ-specific metastatic spreading of tumor cells does not only rely on heterotypic and homotypic adhesive interactions, but also on the interplay of chemokines and their appropriate receptors. Moreover, the identification of cancer stem cells in various tumor tissues has opened new questions. Cancer stem cells possess self-renewal, differentiation, and tumor-initiating capacities. Thus these cells are ideal candidates to be the seed of a secondary tumor. In the present review we will give a brief overview about the complex process of organ-specific metastasis formation depending on the interplay of adhesion molecules, chemokines, and the putative role of cancer stem cells in metastasis formation.

Abstract
The homeobox gene HOXA9 has recently been shown to be an important regulator of endothelial cell (EC) differentiation and activation in addition to its role in embryonic development and hematopoiesis. In this report, we have determined that the EC-leukocyte adhesion molecule E-selectin is a key target for HOXA9. The depletion of HOXA9 protein in ECs resulted in a significant and specific decrease in tumor necrosis factor alpha (TNF-alpha)-induced E-selectin gene expression. In addition, HOXA9 specifically activated the E-selectin gene promoter in ECs. Progressive deletional analyses together with site-specific mutagenesis of the E-selectin promoter indicated that the Abd-B-like HOX DNA-binding motif, CAATTTTATTAA, located in the proximal region spanning bp -210 to -221 upstream of the transcription start site was crucial for the promoter induction by HOXA9. Both HOXA9 in EC nuclear extract and recombinant HOXA9 protein bound to this sequence in vitro. Moreover, we showed that HOXA9 binds temporally, in a TNF-alpha-dependent manner, to the region containing this Abd-B-like element in vivo. We have thus identified a novel and functionally critical cis-regulatory element for TNF-alpha-mediated transient expression of the E-selectin gene. Further, we provide evidence that HOXA9 acts as an obligate proinflammatory factor by mediating cytokine induction of E-selectin.

Abstract
In the development of atherosclerosis, inflammatory cells adhere to and migrate into the vascular walls by interacting with vascular smooth muscle cells. To investigate the mechanism of aspirin's anti-atherogenic activity, we examined whether aspirin inhibits the adhesion of lymphocytes to human aortic smooth muscle cells (AoSMC). Aspirin inhibited T-cell adhesion to AoSMC activated by interleukin 1beta (IL-1beta) in a dose-dependent manner. Antibodies to the adhesion molecules ICAM-1 or VCAM-1, but not to E-selectin, prevented T-cell adhesion. ICAM-1 and VCAM-1 expression stimulated by IL-1beta was reduced by the treatment with aspirin, whereas the expression of E-selectin was unaffected. Nuclear factor kappaB (NF-kappaB) activity was enhanced by IL-1beta and reduced by aspirin, indicating that decreased ICAM-1 and VCAM-1 expression was due to reduced NF-kappaB activity.Thus, aspirin inhibits the adhesion of Jurkat T cells to IL-1beta-activated AoSMC by reducing NF-kappaB activity and decreasing expression of ICAM-1 and VCAM-1, and may prevent the development of atherosclerosis.

Abstract
OBJECTIVE Many processes that are involved in cellular invasion, including blastocyst implantation, placental development, and rapidly growing tumors, occur in reduced oxygen environments. It has been surmised that oxygen tension could regulate the cytotrophoblast ability to differentiate and, as a consequence, to express proteins that are critical for placentation. The objective of the current investigation was therefore to test the hypothesis that placental tissues and trophoblast cells in culture, under low oxygen tension, release angiogenic factors that could affect vascular behavior and invasive potential, thus providing a link between abnormal placentation and maternal vascular abnormality. METHODS Functionally active term placental explant culture and trophoblast cultures were used to demonstrate the secretion profiles of angiogenin and vascular cell adhesion molecule-1 (VCAM-1), and the real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR) technique was employed to demonstrate the mRNA expression under both normoxic and hypoxic conditions. RESULTS A significant increase in the secretion (P <.01) and mRNA expression (P <.01) of angiogenin and a significant decrease in the secretion (P <.04) and mRNA expression (P <.03) of VCAM-1 from both term placental explants and trophoblast cultures subjected to hypoxia in vitro were observed. CONCLUSION Because the primary defect in uteroplacental insufficiency is placental maldevelopment probably associated with hypoxia in situ, this study provides molecular evidence to indicate that the differential expression and secretion of angiogenic factors may play an important role in these pathologic conditions.

Abstract
BACKGROUND Therapeutic angiogenesis for ischemic diseases has been successfully induced by the implantation of autologous bone marrow cells (BMCs). It is understood that interleukin (IL)-1beta increases remarkably in ischemic tissue and has particular effects on angiogenesis. Thus, it is important to clarify how IL-1beta would effect BMCs survival and angiogenic potential. METHODS AND RESULTS The effect of IL-1beta on BMCs survival, adhesion, and endothelial differentiation, as well as the production of angiogenic growth factors, was investigated using an in vitro assessment approach. BMCs were harvested from Zucker obese rats and cultured at a density of 3x10(6) cells/ml with 5 ng/ml IL-1 beta (IL-1beta group) or without IL-1 beta (control group). Survival and adhesion of BMCs were significantly increased in the IL-1beta group than in the control group after 1, 3, and 7 days of culture (p<0.01). The release of vascular endothelial growth factor in supernatant was also significantly higher in the IL-1beta group than in the control group after 3 and 7 days of culture (p<0.01). Furthermore, the number of differentiated endothelial cells derived from BMCs was significantly higher in the IL-1beta group than in the control group after 7 days of culture (p<0.01). CONCLUSIONS These results suggest that IL-1beta has a positive effect on the angiogenic potential of BMCs in vitro.

Abstract
Immune surveillance depends on still poorly understood lymphocyte-endothelium interactions required for lymphocyte transendothelial migration into secondary lymphoid organs. The nuclear factor kappaB (NF-kappaB) regulatory system and its inhibitory IkappaB proteins control the inducible expression of adhesion molecules, cytokines and chemokines involved in endothelial activation and lymphocyte transmigration. Here we present results showing the activation of this system in response to the interaction of high endothelial cells from human tonsils (HUTEC) with human B and T lymphoid cell lines and primary tonsillar lymphocytes. Western blot and electrophoretic mobility shift assays show that adhesion of different lymphoid cells induce varying levels of NF-kappaB activation in HUTEC, with Daudi cells, tonsil-derived B cell line 10 (TBCL-10) and primary tonsillar B lymphocytes causing the strongest activation. The main NF-kappaB protein complexes translocated to the nucleus were p65/p50 and p50/p50. Results from reverse transcription-PCR and flow cytometry analysis of HUTEC indicate that the interaction with Daudi cells induce an increased expression of IL-6 and IL-8 mRNA and cell-surface expression of intercellular adhesion molecule-1, all of which were prevented by sodium salicylate, an inhibitor of NF-kappaB activation. Transwell experiments show that NF-kappaB activation and the response of HUTEC to the interaction of Daudi cells does not depend on direct cell-cell contact but rather on the production of soluble factors that require the presence of both cell types. These results suggest that lymphocytes and high endothelium establish a cross talk leading to NF-kappaB-mediated expression of cytokines and adhesion molecules, inducing endothelial cell activation.

Abstract
In vascular endothelial cells, cytokines induce genes that are expressed in inflammatory lesions partly through the activation of transcription factor NF-kappaB (nuclear factor-kappaB). Among the members of the NF-kappaB/rel protein family, homodimers of the RelA subunit of NF-kappaB can also function as strong transactivators when expressed in cells. However, the functional role of endogenous RelA homodimers has not been clearly elucidated. We investigated whether RelA homodimers are induced in cytokine-treated vascular endothelial cells. Gel mobility-shift and supershift assays revealed that a cytokine TNFalpha (tumour necrosis factor alpha) activated both NF-kappaB1/RelA heterodimers and RelA homodimers that bound to a canonical kappaB sequence, IgkappaB (immunoglobulin kappaB), in SV40 (simian virus 40) immortalized HMEC-1 (human dermal microvascular endothelial cell line 1). In HMEC-1 and HUVEC (human umbilical-vein endothelial cells), TNFalpha also induced RelA homodimers that bound to the sequence 65-2kappaB, which specifically binds to RelA homodimers but not to NF-kappaB1/RelA heterodimers in vitro. Deoxycholic acid, a detergent that can dissociate the NF-kappaB-IkappaB complex (where IkappaB stands for inhibitory kappaB), induced the binding of the RelA homodimers to 65-2kappaB from the cytosolic fraction of resting HMEC-1. Furthermore, TNFalpha induced the transcriptional activity of a reporter gene that was driven by 65-2kappaB in HMEC-1. These results suggest that in addition to NF-kappaB1/RelA heterodimers, TNFalpha also induces RelA homodimers that are functionally active. Thus RelA homodimers may actively participate in cytokine regulation of gene expression in human vascular endothelial cells.

Abstract
PROBLEM Genital herpes simplex infections are generally limited to epithelia and neurons. Vaccines have had activity in herpes simplex virus (HSV)-seronegative women only. Understanding how HSV-specific T cells traffic to infected sites may assist in vaccine design. METHOD OF STUDY Herpes simplex virus epitopes recognized by HSV-specific CD8 T cells were identified and used to make fluorescent human leukocyte antigen (HLA)-peptide tetramers. Molecules related to lymphocyte rolling adhesion were studied by flow cytometry and cell binding. HSV-specific CD4 T cells identified ex vivo by cytokine accumulation or activation marker expression, or detected in vitro by 5-(and-6)-carboxyfluorescein diacetate, succinimidyl ester (CFSE) dilution, were similarly investigated. RESULTS Herpes simplex virus-specific T cells are 10- to 100-fold more prevalent in lesional skin compared with blood and greatly enriched in lesions compared with normal skin. Diverse viral antigens are recognized by HSV-specific T cells. Functionally active E-selectin ligand, and cutaneous lymphocyte antigen (CLA), are expressed by circulating HSV-2-specific CD8 cells. CD4 cells display lower levels of CLA that are dramatically up-regulated upon re-stimulation with antigen. CONCLUSIONS Herpes simplex virus-2-specific CD8 and CD4 T cells differ in constitutive expression of skin homing molecules. Vaccines designed to induce proper homing are postulated to have increased efficacy.

Abstract
Phosphoinositide 3-kinase gamma (PI3Kgamma) in neutrophils plays a critical role in the directed migration of these cells into inflamed tissues. In this study, we demonstrate the importance of the endothelial component of PI3Kgamma activity relative to its leukocyte counterpart in supporting neutrophil interactions with the inflamed vessel wall. Despite the reconstitution of class-Ib PI3K function in neutrophils of p110gamma-/- mice, we observed a 45% reduction in accumulation of these cells in an acute lung injury model. Mechanistically, this appears to result from a perturbation in selectin-mediated adhesion as manifested by a 70% reduction in wild-type (WT) neutrophil attachment to and 17-fold increase in rolling velocities on p110gamma-/- microvessels in vivo in response to tumor necrosis factor alpha (TNFalpha). This alteration in adhesion was further augmented by a deficiency in p110delta, suggesting that the activity of both catalytic subunits is required for efficient capture of neutrophils by cytokine-stimulated endothelium. Interestingly, E-selectin-mediated adhesion in p110gamma-/-) mice was impaired by more than 95%, but no defect in nuclear factor kappa B (NF-kappaB)-induced gene expression was observed. These findings suggest a previously unrecognized partnership between class-I PI3Ks expressed in leukocytes and endothelium, the combination of which is required for the efficient trafficking of immunocompetent cells to sites of inflammation.

Abstract
Recent advances in clinical protocols have improved the outcomes of pancreatic islet transplantation (PIT), yet PIT recipients typically require pancreatic islet grafts derived from multiple donors to achieve insulin independence. This along with experimental models of syngeneic PIT, showing that up to 60% of pancreatic islet tissue undergoes apoptosis within the first several days post-transplantation, strongly suggest the involvement of nonalloantigen-specific, inflammatory events in partial destruction of the graft following PIT. Interleukin-1beta appears to be among the most important inflammatory mediators, causing pancreatic islet dysfunction and apoptosis through the up-regulation of inducible nitric oxide (NO) synthase and cyclooxygenase-2. Kupffer cells secrete many molecules, including cytokines, NO, and free radicals, which are known to be directly toxic to the pancreatic islets, and depletion or inhibition of Kupffer cells improves outcomes following experimental PIT. Immediately after transplantation, the pancreatic islets are perfused only by portal vein blood until the process of angiogenesis restores arterial blood flow some 7-10 days later. This delayed vascularization may have implications for the expression of leukocyte adhesion molecules, the effects of free radicals, and the role of ischemia-reperfusion injury. Finally, in the immediate post-transplant period, hepatocytes may contribute to pancreatic islet injury through the production of NO. This paper reviews literature regarding the inflammatory events that follow PIT as well as the pathogenesis of diabetes and the pathophysiology of hepatic ischemia-reperfusion and their relation to the survival and function of intrahepatic pancreatic islet grafts.

Abstract
Increased expression of adhesion molecules by the activated endothelium is a critical feature of vascular inflammation associated with several disease states such as atherosclerosis. However, mechanisms regulating the endothelial induction of adhesion molecules are not entirely clear. Herein we report that inhibition of the polyol pathway enzyme aldose reductase (AR) prevents the increase in ICAM-1 and VCAM-1 in human umbilical vein endothelial cells (HUVECs) and decreases monocyte adhesion to these cells. In TNF-alpha-stimulated HUVECs, treatment with AR inhibitors sorbinil and tolrestat diminished NF-kappaB activity, phosphorylation and degradation of Ikappa-Balpha, and the nuclear translocation of NF-kappaB. Inhibition of AR abrogated TNF-alpha-induced activation and membrane translocation of PKC, and antisense ablation of AR prevented both TNF-alpha-induced PKC and NF-kappaB activation. However, inhibition of AR did not prevent phorbol ester-induced activation of PKC or NF-kappaB, indicating that inhibition of AR does prevents events upstream of PKC activation. These results identify a novel regulator of endothelial activation and suggest that AR is an obligatory mediator of TNF-alpha signaling leading to an increase in the expression of adhesion molecules and increased binding of monocytes to the endothelium.

Abstract
The advanced glycation end products (AGEs) are a heterogeneous class of molecules, including the following main subgroups: bis(lysyl)imidazolium cross-links, hydroimidazolones, 3-deoxyglucosone derivatives, and monolysyl adducts. AGEs are increased in diabetes, renal failure, and aging. Microvascular lesions correlate with the accumulation of AGEs, as demonstrated in diabetic retinopathy or renal glomerulosclerosis. On endothelial cells, ligation of receptor for AGE (RAGE) by AGEs induces the expression of cell adhesion molecules, tissue factor, cytokines such as interleukin-6, and monocyte chemoattractant protein-1. A chief means by which AGEs via RAGE exert their effects is by generation of reactive oxygen species, at least in part via stimulation of NADPH oxidase. Diabetes-associated vascular dysfunction in vivo can be prevented by blockade of RAGE. Thus, agents that limit AGE formation, increase the catabolism of these species, or antagonize their binding to RAGE may provide new targets for vascular protection in diabetes.

Abstract
The involvement of platelets in the pathogenesis of atherosclerosis has recently gained much attention. Platelet factor 4 (PF4), a platelet-specific chemokine released on platelet activation, has been localized to atherosclerotic lesions, including macrophages and endothelium. In this report, we demonstrate that E-selectin, an adhesion molecule involved in atherogenesis, is up-regulated in human umbilical vein endothelial cells exposed to PF4. Induction of E-selectin RNA is time and dose dependent. Surface expression of E-selectin, as measured by flow cytometry, is also increased by PF4. PF4 induces E-selectin expression by activation of transcriptional activity. Activation of nuclear factor-kappaB is critical for PF4-induced E-selectin expression, as demonstrated by promoter activation studies and electrophoretic mobility shift assays. Further, we have identified the low-density lipoprotein receptor-related protein as the cell surface receptor mediating this effect. These results demonstrate that PF4 is able to increase expression of E-selectin by endothelial cells and represents another potential mechanism by which platelets may participate in atherosclerotic lesion progression.

Abstract
The rapid and transient induction of E-selectin gene expression by inflammatory tumor necrosis factor (TNF)-alpha in endothelial cells is mediated by signaling pathways which involve c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK) kinase pathways. To explore this regulation, we first observed that in the continuous presence of cytokine TNF, activation of JNK-1 in both nuclear and cytoplasmic compartments peaked at 15-30 min, with activity returning to uninduced levels by 60 min. Phosphorylation of both the p38 kinase and its molecular target, the nuclear transcription factor, activating transcription factor-2, were transient after TNF-alpha or interleukin (IL)-1beta induction. However, cycloheximide treatment prolonged the TNF-alpha-induced JNK-1 kinase activity beyond 60 min, suggesting that protein synthesis is required to limit this signaling cascade. We investigated the possible role of the dual-specificity phosphatases MAPK phosphatase (MKP)-1 and MKP-2 in limiting cytokine-induced MAPK signaling. Maximum induction of MKP-1 mRNA and nuclear protein levels by TNF-alpha or IL-1beta were noted at 60 min and their expression correlated with the termination of JNK kinase activity, whereas nuclear levels of MKP-2 were not significantly affected by treatment with TNF-alpha or IL-1beta. Transient overexpression of MKP-1 demonstrated significant specific inhibition of E-selectin promoter activity consistent with a regulatory role for dual-specificity phosphatases. Inhibition of MKP-1 expression through the use of small interfering RNAs prolonged the cytokine-induced p38 and JNK kinase phosphorylation. Our results suggest that endogenous inhibitors of the MAPK cascade, such as the dual-specificity phosphatases like MKP-1 may be important for the postinduction repression of MAPK activity and E-selectin transcription in endothelial cells. Thus, these inhibitors may play an important role in limiting the inflammatory effects of TNF-alpha and IL-1beta.

Abstract
Endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. The aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), intercellular adhesion molecule-1 (sICAM-1) and E-selectin (sE-selectin) in sera of normal and preeclamptic pregnancies. We studied the serum levels of sVCAM-1, sICAM-1 and sE-selectin in normal pregnant women (n=63), mild preeclampsia (n=33) and severe preeclampsia (n=82). Concentrations of soluble adhesion molecules were determined with enzyme-linked immunoassay (ELISA). Serum concentrations of sVCAM-1 were significantly higher in both mild (p=0.004) and severe preeclampsia (p=0.000) than normal pregnancy. There were also significant differences in sVCAM- 1 levels between mild and severe preeclampsia (p=0.002). sICAM-1 levels of severe preeclampsia were statistically different from those of normal pregnancy (p=0.038). Levels of sE-selectin were elevated in both mild (p=0.011) and severe preeclampsia (p=0.000) compared to normal pregnancy, but no statistical difference between the mild and severe preeclampsia (p=0.345). These results suggest that all three soluble adhesion molecules are increased in severe preeclampsia, and sVCAM-1 among them may be useful in predicting the severity of preeclampsia.

Abstract
OBJECTIVE We tested the hypothesis that carvedilol, a beta-adrenoceptor and alpha-adrenoceptor antagonist with potent antioxidant property, could inhibit tumor necrosis factor-alpha (TNF-alpha)-induced endothelial adhesiveness to human mononuclear cells (MNCs), an early sign of atherogenesis. METHODS AND RESULTS Circulating MNCs were isolated from the peripheral blood of healthy subjects. Compared with control condition, pretreatment of carvedilol (10 micromol/L for 18 hours) or probucol (5 micromol/L for 18 hours), but not propanolol, prazosin, or both propanolol and prazosin significantly decreased TNF-alpha-stimulated adhesiveness of cultured human aortic endothelial cells (HAECs) to MNCs. Carvedilol inhibited TNF-alpha-stimulated endothelial vascular cell adhesion molecule-1 (VCAM-1) and E-selectin (66.0+/-2.0% and 55.60+/-1.0% of control, P<0.05, respectively) expression, whereas probucol inhibited only VCAM-1 expression (79.0+/-5.0% of control, P<0.05). Propanolol, prazosin, or both did not alter the expression of adhesion molecules. Further, pretreatment with carvedilol significantly inhibited TNF-alpha-stimulated intracellular reactive oxygen species (ROS) production and the activation of redox sensitive nuclear factor kappa B and activator protein-1 transcription pathways. CONCLUSIONS Carvedilol reduced TNF-alpha-stimulated endothelial adhesiveness to human MNCs by inhibiting intracellular ROS production, transcription factor activation, and VCAM-1 as well as E-selectin expression, suggesting its potential role in clinical atherosclerosis disease.

Abstract
Leukocyte adhesion to endothelial cells plays a key role in inflammatory processes associated with end-organ injury. Endothelin-1 (ET-1), which stimulates inflammatory processes, contributes to cardiovascular damage in deoxycorticosterone (DOCA)-salt hypertension. We investigated whether ETA receptor blockade modulates in vivo leukocyte-endothelial cell interactions and expression of cell adhesion molecules (CAM) involved in these processes. DOCA-salt and control uninephrectomized rats were treated with the ETA antagonist BMS182874 (40 mg/kg per day) or vehicle. Analysis of CAMs expression by reverse transcription-polymerase chain reaction and immunohistochemistry showed increased cardiac platelet selectin (P-selectin), detected mainly in endothelial cells, and vascular cell adhesion molecule-1 (VCAM-1), but not intercellular adhesion molecule-1 (ICAM-1), in DOCA-salt rats. Cardiac expression of endothelial selectin (E-selectin) was decreased, whereas immunoreactivity to ED-1 and myeloperoxidase (MPO) activity, markers of macrophage and leukocyte infiltration, respectively, were increased in DOCA-salt. Leukocyte-endothelial cell interaction, functionally assessed in venules of internal spermatic fascia by intravital microscopy, was significantly altered in DOCA-salt rats as evidenced by increased leukocyte adhesion and decreased rolling. BMS182874 treatment normalized leukocyte-endothelium interactions, decreased cardiac VCAM-1 expression in DOCA and control groups, and had no effects on ICAM-1 expression. BMS182874 also increased E-selectin and abolished P-selectin expression in DOCA-salt, but not in control rats. The ETA antagonist reduced cardiac ED-1 content and MPO activity and prevented cardiac damage in DOCA-salt rats. These data indicate that ET-1 participates, via activation of ETA receptors, in altered leukocyte-endothelial cell interactions in DOCA-salt rats, possibly by modulating expression of CAMs, and that the inflammatory status is associated with cardiac damage in mineralocorticoid hypertension.
