Schizophrenia is associated with chronic low-grade inflammation, which has been linked to increased vascular risk and rates of cardiovascular disease. Levels of vascular endothelial growth factor (VEGF), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) have been related to aging and neurodegeneration, but their role in schizophrenia remains uncertain. Using a cross-sectional, case-control design, this study included 99 outpatients with schizophrenia and 99 healthy comparison subjects (HCs)...

BACKGROUND: Therapeutics targeting tumour necrosis factor (TNF)-α are effective for psoriasis; however, in patients treated for other disorders, psoriasis may worsen and psoriasiform dermatitis (PsoD) may arise. T helper (Th) cytokines in psoriasis upregulate keratin (K)17, which modulates TNF-α transduction, leading to vascular adhesion molecule upregulation and lymphocytic extravasation. AIM: We investigated Th phenotype and expression of K17, intercellular adhesion molecule (ICAM)-1 and vascular adhesion molecule (VCAM)-1 in psoriasis and anti-TNF-α-related PsoD...

Apolipoprotein CIII (ApoCIII) has been shown to be associated with the inflammatory response, but the mechanism of its inflammatory effects remains unclear. Because vascular endothelial cells (VECs) play a key role in the development of inflammation, the present study was performed to investigate inflammatory mechanisms induced by ApoCIII in VECs. In this study, we screened differentially expressed genes (DEGs) using RNA-sequencing. The results identified 390 up-regulated genes and 257 down-regulated genes...

Clinical trials in patients with macular edema due to diabetic retinopathy or retinal vein occlusion (RVO) have shown that suppression of VEGF not only improves macular edema, but also reopens closed retinal vessels, prevents progression of vessel closure, and improves retinopathy. In this study, we show the molecular basis for those clinical observations. Increased retinal levels of VEGF in mice cause plugging of retinal vessels with leukocytes, vessel closure, and hypoxia. Suppression of VEGF reduces leukocyte plugging, causing reperfusion of closed vessels...

BACKGROUND: Microparticles (MPs) are vesicular structures shed from endothelial or circulating blood cells, after activation or apoptosis, and can be considered markers of vascular damage. We aimed to determine the levels of circulating MPs, their content of miRNA-126-3p and 5p, and their relationship with early endothelial activation/damage, in patients with different degree of glucose tolerance. METHODS: CD62E(+), CD62P(+), CD142(+), CD45(+) circulating MPs, their apoptotic (AnnexinV(+)) fractions, and miRNA-126 expression were determined in 39 prediabetic (PreDM), 68 type 2 diabetic (T2DM), and 53 control (NGT) subjects, along with main anthropometric and biochemical measurements...

Diesel exhaust particles (DEP) and their ultrafine fraction (UFP) are known to induce cardiovascular effects in exposed subjects. The mechanisms leading to these outcomes are still under investigation, but the activation of respiratory endothelium is likely to be involved. Particles translocation through the air-blood barrier and the release of mediators from the exposed epithelium have been suggested to participate in the process. Here we used a conditioned media in vitro model to investigate the role of epithelial-released mediators in the endothelial cells activation...

Obstructive sleep apnea syndrome (OSAS) is known to be a risk factor for atherosclerosis (AS), derived from a series of chronic inflammatory reactions caused by hypoxia. However, the association between chronic inflammation and high blood pressure caused by hypoxia remains to be fully elucidated. The aim of the present study was to investigate the effect of continuous positive airway pressure (CPAP) therapy on inflammatory cytokines and AS. A total of 100 patients with OSAS and 50 healthy control subjects were enrolled...

Diabetes with vascular complication needs strict interventions to retard possible serious complications. This research estimated the possible interaction of rosiglitazone (RGN) with losartan (Los) in diabetic rats. Male Spraque Dawly rats were randomly divided into: non-diabetic rats, diabetic rats, and diabetic rats received RGN, Los or combination of RGN and Los. Measurement of serum glucose, vascular adhesion molecule-1 (VCAM-1), interleukin (IL)-6, tumor necrosis factor and (TNF)-α levels, and aortic lipid peroxide (MDA), glutathione (GSH), superoxide dismutase (SOD) and total nitrate/nitrite (NOx) levels were done...

Thioredoxin-interacting protein (TXNIP) emerges as a central regulator for glucose homeostasis, which goes awry in diabetic subjects. Endothelial dysfunction is considered the earliest detectable stage of cardiovascular disease (CVD), a major complication of diabetes. Here, we hypothesize that TXNIP may promote endothelial dysfunction seen in Type 1 diabetes mellitus (T1D). Using a T1D-like rat model, we found that diabetic rats showed significantly higher TXNIP mRNA and protein levels in peripheral blood, compared to their non-diabetic counterparts...

Vascular cell adhesion molecule 1 (VCAM-1) is an important inflammatory biomarker correlating with retinal disease progression. Thus, detection of VCAM-1 mRNA expression levels at an early disease stage could be an important predictive biomarker to assess the risk of disease progression and monitoring treatment response. We have developed VCAM-1 targeted antisense hairpin DNA-functionalized gold nanoparticles (AS-VCAM-1 hAuNP) for the real time detection of VCAM-1 mRNA expression levels in retinal endothelial cells...

Chronic inflammation is a well-known risk factor in development of intestinal tumorigenesis, although the exact mechanisms underlying development of colitis-associated cancer (CAC) still remain obscure. The activity and function of immunoproteasome has been extensively analyzed in the context of inflammation and infectious diseases. Here, we show that the proteasomal immunosubunit LMP7 plays an essential role in development of CAC. Mice devoid of LMP7 were resistant to chronic inflammation and formation of neoplasia, and developed virtually no tumors after AOM/DSS treatment...
