The inflammatory environment is correlated with extracellular matrix (ECM) degradation and chondrocyte hypertrophy in the development of osteoarthritis (OA). Previous studies have reported the anti-inflammatory effects of wogonoside in several diseases. In the present study, we investigated the protective effects of wogonoside in relation to the development of OA and delineated the potential mechanism. In vitro, wogonoside decreased the production of pro-inflammatory cytokines like Nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor alpha (TNF-α), and interleukin-6 (IL-6)...

BACKGROUND: Tolerance to analgesic effects of opioids and dependence to them are main concerns in the treatment of chronic pain conditions, limiting clinical application of these drugs. This study aimed to evaluate the effect of simvastatin on the morphine-induced tolerance and dependence in mice. MATERIAL AND METHODS: For this purpose, mice were treated with either daily morphine (20 mg/kg, s.c.) alone, or in combination with simvastatin (2.5, 5 and 10mg/kg, i...

BACKGROUND: The precise mechanism of action of dimethyl fumarate (DMF) treatment in MS remains unknown. OBJECTIVE: To identify the changes in the blood lymphocyte profile of MS patients predicting no evidence of disease activity (NEDA) status after DMF treatment. METHODS: We studied blood lymphocyte subsets of 64 MS patients treated with DMF at baseline and after 6 months of treatment by flow cytometry. NEDA (41 patients) or ongoing disease activity (ODA, 23 patients) were monitored after a year of follow-up...

BACKGROUND: The Scandinavian Starch for Severe Sepsis/Septic Shock (6S) trial showed increased 90-day mortality with hydroxyethyl starch (HES) 130/0.42 vs. Ringer's acetate. To explore the underlying pathophysiology, we compared early changes in plasma cytokine concentrations between patients resuscitated with HES vs. Ringer's acetate. METHODS: In a subgroup of 226 patients from the 6S trial, we calculated delta plasma concentrations of tumour necrosis factor alpha (TNF-α), interleukin (IL)-6 and IL-10 from randomization to day 2...

The introduction of biological agents has revolutionized the management of many life-threatening and debilitating immune-mediated diseases. Because of the high cost of biological drugs and their patent expiration, the market has opened to biosimilar agents, copy versions of the originators, which can lead to reduced health care expenditure and increase treatment access worldwide. CT-P13 is the first biosimilar of infliximab (IFX) and has been approved for the same indications as its originator drug. It obtained regulatory approval by the European Medicines Agency in September 2013 and by the US Food and Drug Administration in April 2016...

Evolution of tumor cell phenotypes promotes heterogeneity and therapy resistance. Here we found that induction of CD73, the enzyme that generates immunosuppressive adenosine, is linked to melanoma phenotype switching. Activating MAPK mutations and growth factors drove CD73 expression, which marked both nascent and full activation of a mesenchymal-like melanoma cell state program. Proinflammatory cytokines like TNF-alpha cooperated with MAPK signaling through the c-Jun/AP-1 transcription factor complex to activate CD73 transcription by binding to an intronic enhancer...

Tanshinone I from tanshen has been used in traditional Chinese medicine for treating cardiovascular diseases and inflammatory diseases. Given the link between inflammation and Type 2 diabetes mellitus (T2DM), we suspect that tanshinone I may have a beneficial effect on T2DM. This study was to investigate the potential effects of tanshinone I on T2DM and its underlying mechanism. T2DM was thus induced in Sprague-Dawley (SD) rats using streptozotocin (STZ) and high-fat diet. It was observed that T2DM rats had higher levels of total cholesterol (TC), nonesterified fatty acids (NEFAs), total triglyceride (TG) and total low density lipoprotein cholesterol (LDL-C) compared with normal, healthy SD rats...

Intestinal Ischemia/Reperfusion injury (I/R) is associated with a high risk of mortality in the clinical situation. Many factors are involved in I/R including reactive oxygen species (ROS), cytokine release and apoptosis. We aimed to determine whether a pure methyl eugenol (ME) given before intestinal ischemia, protects against intestinal I/R and the possible mechanism involved in this protection. Rat received ME (100 mg/kg) for 30 days then underwent intestinal I/R with 30 min ischemia and 60 min reperfusion...

To evaluate the association of the -308 and -238 tumor necrosis factor alpha (TNF-α) gene polymorphisms with clinical manifestations of dengue and TNF-α serum levels in a northwestern Mexican population. The study populations included dengue fever (DF) and dengue hemorrhagic fever (DHF) patients, and a group of healthy controls (HCs) without history of dengue. Polymerase chain reaction-restriction fragment length polymorphism and Enzyme-Linked Immunosorbent Assay were performed to determine genotypes and serum concentration of TNF-α, respectively...

Sepsis is a life-threatening syndrome accompanied by an overwhelming inflammatory response and organ dysfunction. Selective targeting of phosphodiesterase 4 (PDE4) is currently being investigated as an effective therapeutic approach for inflammation-associated diseases. Roflumilast is a selective PDE4 inhibitor, used for the treatment of severe chronic obstructive pulmonary disease in clinic. However, its role in the treatment of sepsis-induced liver damage remains unclear. In the present study, we evaluated the effects of roflumilast in mice with cecal ligation and puncture-induced sepsis, and investigated the underlying mechanism...

Depression is a recurrent neuropsychiatric disorder that affects millions of individuals worldwide and impact negatively on the patients' social functions and quality of life. Studies have shown that i.p injection of lipopolysaccharide (LPS) induces depressive-like behavior in rodents via induction of oxidative stress and neuroinflammation. Methyl jasmonate (MJ), an isolated compound from jasmine plant has gained reputation in aromatherapy for treatment of depression, nervousness and memory deficits. This study was designed to evaluate the effects of MJ on LPS-induced depressive-like behavior in mice...

This study examined the impact of corticotropin-releasing hormone type 1 receptor (CRHR1) blockade using Antalarmin (ANT) on the expression of markers of neuroplasticity and inflammation, as well as neuroprotection and behavioral recovery following global cerebral ischemia. Male Wistar rats (N=50) were treated with ANT (2μg/2μl; icv) or a vehicle solution prior to a sham or four vessel (4VO) occlusion. Seven days post ischemia, anxiety was assessed in the Elevated Plus Maze and Open Field tests, and fear and spatial learning in a Y-Maze Passive Avoidance Task and the Barnes Maze...

Oxidation-associated malondialdehyde (MDA) modification of proteins can generate immunogenic neo-epitopes that are recognized by autoantibodies. In health, IgM antibodies to MDA-adducts are part of the natural antibody pool, while elevated levels of IgG anti-MDA antibodies are associated with inflammatory and autoimmune conditions. Yet, in human autoimmune disease IgG anti-MDA responses have not been well characterized and their potential contribution to disease pathogenesis is not known. Here, we investigate MDA-modifications and anti-MDA-modified protein autoreactivity in rheumatoid arthritis (RA)...

Inflammatory bowel disease (IBD) is a complex and relapsing inflammatory condition of the gastro intestinal tract characterized by diarrhea and abdominal pain. Farnesoid X receptor (FXR) plays an important role in enteroprotection and mucosal injury by regulating inflammatory responses and barrier function in the intestinal tract. Here we show the mechanisms of FXR agonist, GW4064, inhibits mucosal injury in ileum caused by lipopolysaccharides (LPS). Ileum injury was induced by intraperitoneal injection of LPS in Wild-type (WT) and FXR knockout (KO) mice...
