BACKGROUND: No specific (only subgroup) recommendations for the use of long-acting muscarinic antagonists in chronic obstructive pulmonary disease (COPD) exist. The aim of this exploratory hypothesis generating study was to assess whether different phenotypic/endotypic characteristics could be determinants of the short-term ineffectiveness of the initial tiotropium bromide monotherapy in treatment naïve moderate to severe COPD patients. METHODS: A total of 51 consecutively recruited COPD patients were followed for 3 months after the initial evaluation and prescribed initial treatment (tiotropium)...

Introduction: Inflammatory cytokines secreted from the nucleus pulposus are thought to lead to lumbar nerve root compression-like symptoms. Tumor necrosis factor-alpha (TNF-α), an inflammatory cytokine, likely plays an important role in lumbar disc hernia-related leg pain. In this experimental study, we compared the effectiveness of TNF-α antagonists administered through the intravenous or epidural route in lumbar spine pathologies. Materials and Methods: After ethics committee approval had been obtained, 24 Sprague Dawley male rats aged 70-90 days and weighing 250-300 g each were allocated to four groups...

OBJECTIVES: Anti-tumor necrosis factor alpha (anti-TNF-α) agents are generally well tolerated, yet they can be associated with serious adverse events (SAEs) in a minority of patients. We examined the incidence of SAEs in a pediatric referral center for chronic rheumatologic and gastroenterological inflammatory disorders. METHODS: Retrospective analysis of SAEs occurring during treatment with anti-TNF-α agents in patients with juvenile idiopathic arthritis (JIA) (n = 78)  or pediatric-onset inflammatory bowel disease (IBD) (n = 105) seen at the Institute for Maternal and Child Health IRCCS "Burlo Garofolo" in Trieste, Italy, between June 2001 and February 2016...

The mechanisms of chronic postsurgical pain remain to be elucidated.. We reported here that skin/muscle incision and retraction (SMIR), a rat model of postsurgical pain, phosphorylated the extracellular regulated protein kinases (ERK) signaling components c-Raf, MEK (ERK kinase) and ERK1/2 in lumbar 3 dorsal root ganglion (L3 DRG) in rats. Intrathecal injection of ERK specific inhibitor SCH772984 suppressed the mechanical allodynia induced by SMIR. Further more, SMIR upregulated tumor necrosis factor alpha (TNFα) in L3 DRG, which could be inhibited by SCH772984...

JNJ7777120, a histamine H4 receptor antagonist, was shown to be effective in different experimental settings of allergic inflammation, including contact hypersensitivity. Toll-like receptors (TLRs) are thought to function as a link between innate and adaptive immune responses to various haptens. Here, we studied the suppression of TLR signaling as a possible mechanism by which JNJ7777120 exerts its anti-inflammatory effects against the chemical hapten, fluorescein isothiocyanate (FITC). The potential anti-oxidant effect of JNJ7777120 in this model was also examined...

The anti-inflammatory actions of sevoflurane postconditioning are suggested as an important mechanism of sevoflurane postconditioning-induced neuroprotection against cerebral ischemia. Here, we determined whether the anti-inflammatory effects of sevoflurane postconditioning were mediated via inhibition of the toll-like receptor (TLR)-4/nuclear factor kappa B (NF-κB) pathway after global transient cerebral ischemia in rats. Forty-five rats were randomly assigned to five groups as follows: (1) control (10 min of ischemia, n = 10); (2) sevoflurane postconditioning (two periods of sevoflurane inhalation after ischemia for 10 min with a wash period of 10 min, n = 10); (3) resatorvid (intraperitoneal injection of a selective TLR-4 antagonist (3 mg/kg) 30 min before ischemia, n = 10); (4) sevoflurane postconditioning plus resatorvid (n = 10), and sham (n = 5)...

Lysophosphatidic acid (LPA) is a pleiotropic signaling lipid that acts as ligand for at least six specific G-protein coupled receptors. Schwann cells (SC) are known to mainly express the LPA1 receptor subtype. An emerging body of evidence has linked LPA with injury-induced peripheral nerve demyelination as well as neuropathic pain. However, the molecular mechanisms underlying its demyelinating effect have not been conclusively elucidated. We aimed to decipher the demyelinating effect in vitro as well as in vivo by studying markers of SC differentiation and dedifferentiation: Myelinated dorsal root ganglia (DRG) cultures were treated either with LPA, LPA plus AM095 (LPA1 antagonist) or vehicle...

Pro-inflammatory cytokine exposure in early postnatal life triggers clear neurotoxic effects on the developing hippocampus. Tumor necrosis factor alpha (TNF-α) is one of the inflammatory mediators and is a potent inhibitor of neurogenesis. Memantine (MEM) is an uncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist that has been demonstrated to increase the proliferation of hippocampal progenitor cells. However, the effects of MEM on TNF-α-mediated impairment of hippocampal precursor proliferation remain unclear...

BACKGROUND: Lead (Pb), cadmium (Cd), and arsenic (As) could cause health issues through oxidative stress that is indicated in the elevated tumor necrosis factor-alpha (TNF-α). However, some of the essential elements-selenium (Se), zinc (Zn), cobalt (Co), and copper (Cu)-are cofactors or structural components of antioxidant enzymes. It is suggested that single-nucleotide polymorphisms (SNPs) in the TNF-α gene have different TNF-α responses. This study aims to evaluate the effect of serum TNF-α levels through the interactions between toxic metals and essential elements and how the interactions between the toxic metals and TNF-α SNPs (-1031 T > C, -863 C > A, -857 C > T, -308 G > A, -238 G > A) influence serum TNF-α levels...

Plaque psoriasis and pustular psoriasis are overlapping, but distinct, disorders. The therapeutic response to biologics supports the pivotal role of the tumour necrosis alpha (TNF-α)/ interleukin (IL)-23/IL-17/IL-22 axis in the pathogenesis of these disorders. Recently, functional activation of the IL-36 receptor (IL-36R) was discovered to be another driving force in the pathogenesis of psoriasis. This was first highlighted by the discovery that a loss-of-function mutation of the IL-36R antagonist (IL-36Ra) causes pustular psoriasis...

Loss of cardiomyocytes occurs with aging and contributes to cardiovascular complications. In the present study, we highlighted the role of clusterin, a protein that has recently been associated with the protection of cardiomyocytes from apoptosis. Clusterin protects cardiac cells against damage from myocardial infarction, transplant, or myocarditis. Clusterin can act directly or indirectly on apoptosis by regulating several intracellular pathways. These pathways include (1) the oxidant and inflammatory program, (2) insulin growth factor 1 (IGF-1) pathway, (3) KU70 / BCL-2-associated X protein (BAX) pathway, (4) tumor necrosis factor alpha (TNF-α) pathway, (5) BCL-2 antagonist of cell death (BAD) pathway, and (6) mitogen-activated protein kinase (MAPK) pathway...

Tumor Necrosis Factor alpha (TNF-α) has been shown to be released by tumor cells in response to docetaxel, and lipopolysaccharides (LPS), the latter through activation of toll-like receptor 4 (TLR4). However, it is unclear whether the former involves TLR4 receptor activation through direct binding of the drug to TLR4 at the cell surface. The current study was intended to better understand drug-induced TNF-α production in tumor cells, whether from short-term drug exposure or in cells selected for drug resistance...

Pathogens can cause inflammation when inoculated into the skin. The vector-transmitted protozoan parasite Trypanosoma cruzi induces poor cellular-infiltration and disseminates, causing high mortality in the experimental model. Here, we characterized the inflammatory foci at the parasite inoculation site and secondary lymphoid organs using a murine model. While no macrophages and few neutrophils and monocytes (Mo) were recruited into the skin, T. cruzi infection elicited the mobilization of Ly6C(+) Mo to draining lymph nodes and spleen...

Curcumin is a phenolic compound that exhibits beneficial properties for cardiometabolic health. We previously showed that curcumin reduced the infiltration of immune cells into the vascular wall and prevented atherosclerosis development in mice. This study aimed to investigate the effect of curcumin on monocyte adhesion and transendothelial migration (TEM) and to decipher the underlying mechanisms of these actions. Human umbilical vein endothelial cells (HUVECs) were exposed to curcumin (0.5-1μM) for 3h prior to their activation by Tumor Necrosis Factor alpha (TNF-α)...
