Renal ischemia/reperfusion (I/R) injury is strongly related to morbidity and mortality. Oxidative stress, inflammation, and apoptosis play key roles in renal dysfunction following renal I/R. Aripiprazole is an atypical antipsychotic which used for the treatment of schizophrenia and bipolar disorder. Recent studies have reported aripiprazole as displaying certain anti-inflammatory effects. Regarding the underlying mechanisms of renal ischemia-reperfusion, therefore, nephroprotective effects might be predicted to be seen with aripiprazole...

Esophageal cancer is the sixth most common cause of cancer-related death worldwide. Current chemotherapy regimens include a combination of 5-fluorouracil (5-FU) and cisplatin, but more efficient therapy strategies are needed to increase 5-year survival. Alterations in the signaling pathway of the tumor suppressor gene Rb-1, which encodes a phosphoprotein (pRB) that negatively regulates the G1/S transition of the cell cycle, are present in 70% of all tumors, but its role in esophageal cancer is still unclear...

Asiatic acid, a triterpenoid compound derived from Centella asiatica, has been demonstrated to have antioxidant and anti-inflammatory effects. The present study evaluated the effects of asiatic acid on hemodynamic alterations, renin-angiotensin system (RAS), oxidative stress, and inflammation in 2K-1C hypertensive rats. Renovascular hypertension was induced in male Sprague-Dawley rats and treated with vehicle, asiatic acid (30 mg/kg/day), or captopril (5 mg/kg/day) for 4 weeks. We observed that 2K-1C hypertensive rats exhibited hemodynamic alterations such as high blood pressure, heart rate, hindlimb vascular resistance, and low hindlimb blood flow...

Neuroinflammation has been recognized as a factor in the pathogenesis of neurodegenerative diseases. Esculentoside A (EsA), a saponin isolated from Phytolacca esculenta, has been reported to have anti-inflammatory activity. However, little research has been reported on the anti-neuroinflammatory effects of EsA. EsA concentration-dependently suppressed LPS-induced TNF-α, IL-1β, and PGE2 production. LPS-induced NF-κB activation was inhibited by treatment of EsA. Furthermore, EsA concentration-dependently up-regulated the expression of PPAR-γ...

OBJECTIVE: Serum anti-citrullinated peptide antibodies (ACPA) may be present before development of rheumatoid arthritis (RA) and may predict more severe, erosive disease. This study examines synovial tissue immunophenotype according to ACPA status in RA patients, response to treatment and erosive status. METHODS: Consecutive RA patients were prospectively recruited and underwent clinical and serological assessment before and after treatment. Radiological assessment was performed at the time of clinical follow up...

Multi-glycoside of Tripterygium wilfordii Hook. f. (GTW) has been proven to be clinically effective in relieving microinflammation in patients with early diabetic nephropathy (DN). However, the therapeutic mechanisms involved in vivo remain unclear. In the process of early DN, microinflammation and activation of p38 mitogen‑activated protein kinase (MAPK) and canonical nuclear factor (NF)-κB signaling pathways are the important mechanisms by which hyperglycemia contributes to glomerulosclerosis (GS)...

In recent years, phosphodiesterase (PDE) inhibitors have been frequently tested for the treatment of experimental inflammatory and immune disorders. It is suggested that anti-inflammatory properties of PDE inhibitors are related to their ability to increase cAMP levels. The aim of this study was to verify the hypothesis that cAMP may be a useful marker of pharmacological response following administration of non-selective PDE inhibitors (pentoxifylline and (±)-lisofylline) to endotoxemic rats. Male Wistar rats were administered LPS (1 mg kg(-1), i...

OBJECTIVES: TNF is one of the key cytokines involved in cancer development. TNF signaling can result in both stimulating and inhibitory signals that can result in opposite biological effects in cancerogenesis. 2-(1-adamantylamino)-6-methylpyridine (AdAMP) enhances TNF secretion whereas N-a-tosyl-L-phenylalanine chloromethyl ketone (TPCK) is a NF-κB inhibitor potentially stimulating proapoptotic TNF signals. The aim of the study was to assess the effect of TPCK in combination with AdAMP on human ovarian cells...

Toll-like receptor (TLR)3 is a key component of the innate immune response to viral infection. The present study firstly examined whether sex differences exist in TLR3-induced inflammatory, endocrine, and sickness responses. The data revealed that TLR3-induced expression of interferon- or NFkB-inducible genes (IFN-α/β, IP-10, or TNF-α), either peripherally (spleen) or centrally (hypothalamus), did not differ between male and female rats, with the exception of TLR3-induced IFN-α expression in the spleen of female, but not male, rats 8 hr post TLR3 activation...

BACKGROUND: Metabolic syndrome (MetS) is an obesity-driven condition of pandemic proportions that increases the risk of type 2 diabetes and cardiovascular disease. Pathophysiological mechanisms are poorly understood, though inflammation has been implicated in MetS pathogenesis. The aim of this study was to assess the effects of galantamine, a centrally acting acetylcholinesterase inhibitor with antiinflammatory properties, on markers of inflammation implicated in insulin resistance and cardiovascular risk, and other metabolic and cardiovascular indices in subjects with MetS...

X-linked Inhibitor of Apoptosis (XIAP) deficiency predisposes people to pathogen-associated hyperinflammation. Upon XIAP loss, Toll-like receptor (TLR) ligation triggers RIPK3-caspase-8-mediated IL-1β activation and death in myeloid cells. How XIAP suppresses these events remains unclear. Here, we show that TLR-MyD88 causes the proteasomal degradation of the related IAP, cIAP1, and its adaptor, TRAF2, by inducing TNF and TNF Receptor 2 (TNFR2) signaling. Genetically, we define that myeloid-specific cIAP1 loss promotes TLR-induced RIPK3-caspase-8 and IL-1β activity in the absence of XIAP...

High serum concentrations of TNF-related apoptosis-inducing ligand (TRAIL), a member of the tumor necrosis factor protein family, are found in patients with increased BMI and serum lipid levels. In a model of murine obesity, both the expression of TRAIL and its receptor (TRAIL-R) is elevated in adipose tissue. Accordingly, TRAIL has been proposed as an important mediator of adipose tissue inflammation and obesity-associated diseases. The aim of this study was to investigate if TRAIL regulates inflammatory processes at the level of the adipocyte...

Trypanosoma cruzi infection triggers a chronic inflammatory process responsible for the alterations in the extracellular matrix and functionality of the heart. The angiotensin converting enzyme (ACE) inhibitors affects T. cruzi in vitro surveillance and modulates in vivo some inflammatory mediators. In this study, we investigated the treatment with an ACE inhibitor (Enalapril) and the Benznidazole (Bz) in a single and combination therapies (CT) in C57BL/6 mice infected with VL-10 strain of the T. cruzi. Animals were treated during 20days with different doses of Bz (100, 80, 60mg/kg), Enalapril (25, 20, 15mg/kg) and their CT (100+25; 80+20; 60+15mg/kg) and euthanized at 30° (acute) and at 120° (chronic) days post infection...

Tumor necrosis factor (TNF)-α inhibitors target TNF-α to effectively treat autoimmune inflammatory conditions, such as rheumatoid arthritis. However, many cases of cutaneous and systemic vasculitis related to TNF-α inhibitors have been reported in the literature. Here, the authors report the first case of a 61-year-old Japanese woman who developed leukocytoclastic vasculitis with cutaneous perivascular hemophagocytosis, which was related to elevated cytokines and immune complexes after initiating adalimumab for rheumatoid arthritis without evidence of hemophagocytic syndrome and rarely encountered in the skin...

Biologic therapies are effective treatments for psoriasis and are often used in women of childbearing age. To evaluate the safety of biologic therapy in conception and/or pregnancy, we have performed a systematic review of Pubmed, MEDLINE, EMBASE and Cochrane databases for multivariable adjusted studies of women exposed to biologic therapy relevant to the treatment of psoriasis during conception and/or pregnancy. We identified four population-based cohort studies involving 1300 women exposed to TNF-α inhibitors (TNFi) 3 months prior to or during the first 3 months of pregnancy...

TNF inhibitors have been used in ankylosing spondylitis (AS). The efficacy of TNF inhibitors was already evaluated by meta-analysis of randomized controlled trials (RCTs). However, the safety of TNF inhibitors is still unclear. Therefore, we aimed to evaluate and update the safety data from RCTs of TNF inhibitors in patients treated for AS. A systematic literature search was conducted from 1990 through May 31, 2016. All studies included were randomized, double-blind, controlled trials of patients with ankylosing spondylitis that evaluated adalimumab, certolizumab pegol, etanercept, golimumab, or infliximab treatment...

Necroptosis is a regulated form of cell death involved in several disease models including in particular liver diseases. Receptor-Interacting Protein Kinases, RIPK1 and RIPK3, are the main serine/threonine kinases driving this cell death pathway. We screened a non-commercial kinase-focused chemical library allowed us to identify Sibiriline as new inhibitor of necroptosis induced by TNF in Fas-Associated protein with Death Domain (FADD)-deficient Jurkat cells. Moreover, Sib inhibits necroptotic cell death induced by various death ligands in human or mouse cells while not protecting from caspase-dependent apoptosis...
