#1
Seok-Joo Kim, Rachelle P Davis, Craig N Jenne
Platelets have classically been considered crucial effector cells in hemostasis, but now are increasingly recognized as players during inflammatory responses in innate and adaptive immunity. Platelets can recognize and kill invading pathogens, and, upon stimulation, also release a wide array of mediators that modify immune and endothelial cell responses. Increased platelet activity can protect the host against infectious insults; however, the excessive activity can lead to inflammation-mediated tissue damage...

Retinal vascular endothelial growth factor (VEGF) increased by neovascularization is well known as a pathogenic factor in ocular neovascular diseases. However, it is still unclear how retinal neurons are damaged by VEGF. The aims of this study are to demonstrate the inflammatory protein expression regulated by VEGF using mouse photoreceptor-derived cells and the protective effect of quercetin against VEGF-induced inflammatory response. Expression and phosphorylation of protein and expression of mRNA were detected by immunoblot and reverse transcriptase polymerase chain reaction...

The precise mechanism by which diabetes impairs spermatogenesis and testicular function is not exactly known. Vascular endothelial growth factor (VEGF) and poly(ADP-ribose) polymerase-1 (PARP-1) are important for germ cell homeostasis and repair of DNA respectively. The aim of this study was to investigate the correlation between diabetes-induced testicular damage and testicular VEGF and PARP-1 expression and the possible protective role of vitamin E supplementation. A total of 45 male Wistar albino rats were randomly divided into three groups: Group I (nondiabetic rats), Group II (streptozocin-induced diabetic rats) and Group III (streptozocin-induced diabetic rats treated orally with 0...

Uncoupling protein 2 (UCP2) is an inner mitochondrial membrane protein that belongs to the uncoupling protein family and plays an important role in lowering mitochondrial membrane potential and dissipating metabolic energy with prevention of oxidative stress accumulation. In the present article, we will review the evidence that UCP2, as a consequence of its roles within the mitochondria, represents a critical player in the predisposition to vascular disease development in both animal models and in humans, particularly in relation to obesity, diabetes, and hypertension...

Tissue regenerative medicine combines the use of cells, scaffolds and molecules to repair damaged tissues. Different cell types are employed for musculoskeletal diseases, both differentiated and mesenchymal stromal cells (MSCs). In recent years, the hypothesis that cell-based therapy is guided principally by cell-secreted factors has become increasingly popular. The aim of the present literature review was to evaluate preclinical and clinical studies that used conditioned medium (CM), rich in cell-factors, for musculoskeletal regeneration with a cell-free approach...

Importance: Nonalcoholic fatty liver disease (NAFLD) is a common condition that is most often asymptomatic. It is associated with metabolic syndrome, incident diabetes, carotid atherosclerosis, and endothelial dysfunction, conditions that in turn are strongly linked with brain damage and cognitive impairment. However, it is not known whether NAFLD is associated with structural brain measures in humans. Objective: To assess the association between prevalent NAFLD and brain magnetic resonance imaging (MRI) measures...

Primary varicella zoster virus (VZV) infection, predominantly in the pediatric population, presents with pyrexia and a classic pruritic vesicular rash. In adults, although less common, it is more severe and linked to more complications. Neurological complications, which account for less than 1% of all VZV complications, include meningitis, encephalitis, arterial vasculopathy, and venous thrombosis. We present a case of a 39-year-old male who developed extensive cerebral venous sinus thrombosis following primary VZV infection...

Shiga toxin is the main virulence factor of enterohemorrhagic Escherichia coli, a non-invasive pathogen that releases virulence factors in the intestine, causing hemorrhagic colitis and, in severe cases, hemolytic uremic syndrome (HUS). HUS manifests with acute renal failure, hemolytic anemia and thrombocytopenia. Shiga toxin induces endothelial cell damage leading to platelet deposition in thrombi within the microvasculature and the development of thrombotic microangiopathy, mostly affecting the kidney. Red blood cells are destroyed in the occlusive capillary lesions...

Endothelial progenitor cells (EPCs) contribute to neovasculogenesis and reendothelialization of damaged blood vessels to maintain the endothelium. Dysfunction of EPCs is implicated in the pathogenesis of vascular injury induced by homocysteine (Hcy). We aimed to investigate the role of Cyclin A in Hcy-induced EPCs dysfunction and explore its molecular mechanism. In this study, by treatment of EPCs with Hcy, we found that the expression of Cyclin A mRNA and protein were significantly downregulated in a dose-dependent manner...

Blood-brain barrier (BBB) breakdown has been determined to play a critical role in the pathogenesis of Alzheimer's disease (AD). However, the underlying mechanisms of BBB disruption in AD remain unclear. Our previous study suggested that the receptor for advanced glycation end-products (RAGE) functioned as a signal transduction receptor in Aβ1-42-induced damage in endothelial cells. In our present study, we revealed that RAGE-mediated endoplasmic reticulum stress (ERS) is essential for Aβ-induced endothelial cell damage...

AIM: In vivo vascular smooth muscle cell (VSMC) EGF receptor (EGFR) contributes to acute angiotensin II (AII) effects on vascular tone and blood pressure. The ubiquitously expressed EGFR has been implicated in vascular remodeling preceding end-organ damage by pharmacological inhibition, and AII signaling in cultured vascular cells is partly EGFR dependent. However the role of VSMC-EGFR in vivo during AII-induced pathophysiological processes is not known. METHODS: The present study assesses the in vivo relevance of VSMC-EGFR during chronic AII challenge without further stressors, using a mouse model with inducible, VSMC-specific EGFR knock out (VSMC-EGFR-KO)...

Epithelioid hemangioma is a locally aggressive vascular neoplasm, found in bones and soft tissue, whose cause is currently unknown, but may involve oncogene activation. FOS was one of the earliest viral oncogenes to be characterized and normal cellular FOS forms part of the activator protein 1 (AP-1) transcription factor complex which plays a pivotal role in cell growth, differentiation and survival as well as the DNA damage response. Despite this, to date, a causal link between aberrant FOS function and naturally occurring tumors has not been established...

Background and Objective Statins, 3-hydroxyl-3-methyl-glutharyl Coenzyme A reductase inhibitors showed their therapeutic potential in the treatment of atherosclerosis-related diseases. Recently, the properties of statins, separate from their lipid lowering activity have attracted much attention. These properties that cover a wide area of physiopathological activities including cell maturation, immune response regulation, tissue fibrosis, endothelial activity and are called pleiotropic activity. Many in vitro studies demonstrated significant, statins-dependent regulation of immune system reactivity, reduction of pro-inflammatory and pro-fibrotic cytokines as well as suppression of endothelial activity and damage...
