Hemodialysis (HD) patients experience vascular calcification, ultimately leading to high mortality rates. Previously, we reported associations between soluble receptor for advanced glycation end products (sRAGEs) and extracellular newly identified RAGE-binding protein S100A12 (EN-RAGE) and vascular calcification. Here, we extended our observations, investigating whether these biomarkers may be useful for predicting cardiovascular morbidity and mortality in these subjects. Thus, we evaluated the relationship between sRAGE and S100A12 and mortality in long-term HD patients...

Mycobacteria are a major human health problem globally. Regarding tuberculosis the situation is worsened by the poor efficacy of current vaccine regimens and by emergence of drug-resistant strains (Manjelievskaia J et al, Trans R Soc Trop Med Hyg 110: 110, 2016; Pereira et al., Lancet Infect Dis 12:300-306, 2012; http://www.who.int/tb/publications/global_report/en/) undermining both disease-prevention and available treatments. Thus, increased basic understanding of mycobacterial-and particularly Mycobacterium tuberculosis-virulence strategies and pathogenesis is of great importance...

Stroke is an important risk factor for bone fracture. We showed previously that bone fracture at the acute stage of ischemic stroke worsens, and activation of α-7 nicotinic acetylcholine receptor (α-7 nAchR) improves, stroke recovery by attenuating inflammation. We hypothesized that activation of α-7 nAchR also improves the blood-brain barrier (BBB) integrity. Permanent distal middle cerebral artery occlusion (pMCAO) was performed on C57BL/6J mice followed by tibia fracture 1 day later. Mice were treated with 0...

Until now, the surface markers of multipotent mesenchymal stem cells (MSCs) had not been fully identified. Here, we found that the IGF1 receptor (IGF1R), regarded as a pluripotent marker of embryonic stem cells (ESCs), was also expressed in human dental pulp derived-mesenchymal stem cells (hDSCs), which displayed a potential for both self-renewal and multipotency. hDSC-secreted IGF1 interacted with IGF1R through an autocrine signaling pathway to maintain this self-renewal and proliferation potential. Stereotaxic implantation of immunosorted IGF1R(+) hDSCs in rats with neonatal hypoxia-ischemia (NHI) promoted neuroplasticity, improving the neurological outcome by increasing expression of the anti-apoptotic protein Bcl-2, which enhanced both neurogenesis and angiogenesis...

Leukotriene A4 hydrolase has been identified as an enzyme with dual anti- and pro-inflammatory role, thus, the conversion of leukotriene to leukotriene B4 in the initiation stage of inflammation and the removal of the chemotactic Pro-Gly-Pro tripeptide. These findings make leukotriene A4 hydrolase an attractive drug target: suggesting an innovative approach towards the identification and design of novel class of compounds that can selectively inhibit leukotriene B4 synthesis while sparing the aminopeptidase activity...

Oxidative stress induced by hemorrhagic shock (HS) initiates a systemic inflammatory response, which leads to subsequent kidney injury. This study assessed the efficacy of c-type natriuretic peptide (CNP) in attenuating kidney injury in a rat model of hemorrhagic shock and resuscitation (HS/R). Sodium pentobarbital-anesthetized adult male Wistar rats underwent HS induced by the withdrawal of blood to a mean arterial pressure of 30-35 mmHg for 50 min. Then, the animals received CNP (25 μg/kg) or vehicle (saline) intravenously, followed byresuscitation with 1...

Convergent evidence indicates that abnormalities in the innate immune system may be pertinent to the pathogenesis, phenomenology, and possible treatment of several mental disorders. In keeping with this view, the targeting of interleukin-6 with the human monoclonal antibody sirukumab may represent a possible treatment and disease modification approach, for adults with brain-based disorders (e.g., major depressive disorder). A PubMed/Medline database search was performed using the following search terms: sirukumab; anti-IL-6; IL-6; major depressive disorder; inflammation...

Inflammation of synovial membrane and degeneration of articular cartilage in osteoarthritis (OA) lead to major changes in joint space width (JSW) and biochemical components such as collagen-II telopeptide (CTX-II) and matrix metallo protineases (MMP-3, 8, and 13). Low-level laser therapy (LLLT) is thought to have an analgesic effect as well as biomodulatory effect on microcirculation and cartilage regeneration in animal studies. The objective of this study was to examine the analgesic and biochemical effect of LLLT in patients with knee osteoarthritis...

Several epidemiological investigations indicate that cancer survivors have a lower risk for Alzheimer's disease (AD) and vice versa. However, the associations between plasma amyloid-beta (Aβ) levels with cancer remain largely unknown. In this case-control study, 110 cancer patients, 70 AD patients, and 70 age- and gender-matched normal controls were recruited. The cancer types include esophagus cancer, colorectal cancer, hepatic cancer, and lung cancer, all of which were reported to be associated with a lower risk for AD...

Herpes simplex virus type 1 (HSV-1) encephalitis causes a deleterious inflammation and elevated intracranial pressure. As a step towards examining the origin of the inflammation, we here report the response of circulating proteasomes and complement factors in blood and cerebrospinal fluid (CSF) in rats infected with HSV-1. Infection was via the nasal route, with 1.1 × 10(4) plaque-forming units of HSV-1 strain 2762 given in one or both nostrils. A sandwich enzyme-linked immunosorbent assay was used to study the level of 26S proteasomes and their complex formation with complement factors 3 and 4...

PURPOSE: Fatigue is a prevalent and burdensome effect of breast cancer. Fatigue has been linked to chronic inflammation, and diets high in antioxidant nutrients have been associated with lesser prevalence and severity of fatigue. Studies are needed, however, to test if antioxidant-rich diets could improve fatigue. METHODS: Pilot, randomized, trial conducted between January 2014 and April 2015, to investigate if a 3-month diet rich in fruit, vegetables, whole grains, and omega-3 fatty acid-rich foods, named the fatigue reduction diet (FRD), improved fatigue and sleep compared to an attention control, named the general health curriculum (GHC)...

Asthma is a heterogeneous disease characterized by symptoms of chronic inflammation and airway structural and functional changes. It affects about 300 million people worldwide and causes 250 000 deaths annually, but its symptoms can be greatly relieved by regular use of inhaled glucocorticoids (GCs). GCs exert their function through interacting with glucocorticoid receptors (GRs). Diosgenin is a naturally occurring steroidal saponin abundantly present in many medicinal plants, including Dioscorea nipponica, which shares a similar steroidal structure with GC...

We identified and characterized the function of CD45(+)/collagen I(+) fibrocytes in acutely injured skeletal muscle of wild-type (WT) and Ccr2(-/-) mice, and in quadriceps and diaphragm muscles of mdx(5cv) mice, a mouse model for Duchenne muscular dystrophy. Fibrocytes were not detected in peripheral blood of WT mice after acute muscle injury or mdx(5cv) mice. Fibrocytes were detected in acutely injured muscles and in mdx(5cv) quadriceps and diaphragm muscles. These cells expressed F4/80 and CCR2, and they were mostly Ly6C(lo) They expressed a low level of collagens but a high level of profibrotic growth factors as compared with i...

Neutrophil migration is an essential step in leukocyte trafficking during inflammatory responses. Semaphorins, originally discovered as axon guidance cues in neural development, have been shown to regulate cell migration beyond the nervous system. However, the potential contribution of semaphorins in the regulation of neutrophil migration is not well understood. This study examines the possible role of a secreted chemorepellent, Semaphorin 3E (Sema3E), in neutrophil migration. In this study, we demonstrated that human neutrophils constitutively express Sema3E high-affinity receptor, PlexinD1...

The emergence of avian H7N9 influenza A virus (IAV) in humans with associated high mortality, has highlighted the threat of a potential pandemic. Fatal H7N9 infections are characterised by hyperinflammation and increased cellular infiltrates in the lung. Currently there are limited therapies to address the pathologies associated with H7N9 infection and what virulence factors may contribute to these pathologies. We have found that PB1-F2 derived from H7N9 activates the NLRP3 inflammasome and induces lung inflammation and cellular recruitment that is NLRP3 dependent...

: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely used medicine to treat pain, fever, inflammation and to inhibit platelet function. Understanding the expression regulation of enzymes of the prostanoid pathway is of great medical relevance. Histone acetylation crucially controls gene expression. We set out to identify the impact of histone deacetylases (HDACs) on the generation of prostanoids and examine the consequences on vascular function. Inhibition of HDACs (HDACi) with the pan HDAC inhibitor SAHA attenuated prostaglandin E2 (PGE2) generation in the murine vasculature and in human vascular smooth muscle cells...
