Occurrence of hepatotoxicity following prescription of etanercept, a tumor necrosis factor-alpha (TNF-α) antagonist, is a relatively well-known issue. On the other hand, acute hepatic failure which could lead to liver transplantation is extremely rare to the best of our knowledge, and there is no previously published case in the literature. In this article, we presented a case of acute liver failure followed by liver transplantaion, in a 32- year old man with a previous history of ankylosing spondylitis after etanercept usage...

Artemisinin (ART) was initially described for the control of inflammation and pain. However, the mechanisms involved with its antinociceptive effect are still poorly understood. Thus, this present study aimed to investigate the effect of ART in both free and nanocapsulated form on postoperative pain, as well as the participation of the spinal Toll-like receptor 4 (TLR4) in this process. Postoperative pain was induced using the skin/muscle incision retraction (SMIR) model in male Swiss mice. After 3 and 28 days of SMIR, the animals received an intrathecal injection of free or nanocapsulated ART, and the nociceptive threshold was evaluated by von Frey filament test...

Brain edema following brain infarction affects mobility and mortality. The mechanisms underlying this process remain to be elucidated. Animal studies have shown that aquaporin-4 (AQP4) expression in astrocytes increases after stroke, and its deletion significantly reduces brain swelling. Recently, two kinds of cells, resident microglia-derived macrophage-like cells (MG-MΦ) and bone marrow-derived macrophages (BM-MΦ), have been reported to accumulate in the ischemic core and stimulate adjacent astrocytes. Therefore, we hypothesized that these cells play crucial roles in the expression of AQP4 and ultimately lead to exacerbated brain edema...

Our previous study showed that propane-2-sulfonic acid octadec-9-enyl-amide (N15), a novel peroxisome proliferator-activated receptor α and γ (PPARα/γ) dual agonist, inhibits inflammatory responses in tumor necrosis factor alpha (TNFα)-induced vascular endothelial cells or lipopolysaccharide (LPS)-induced human myeloid leukemia mononuclear cells-1. However, little is known about whether N15 applies to other pathological or neuroinflammatory conditions. In the present study, we detected the effect of N15 on the LPS-induced neuroinflammatory response in mice and further investigated whether the effect of N15 on neuroinflammation and neuronal cells survival was related to PPARα/γ dual pathways...

With the objective of linking early findings relating to the novel SARS-CoV-2 coronavirus with potentially informative findings from prior research literature and to promote investigation toward therapeutic response, a coherent cellular and molecular pathway is proposed for COVID-19. The pathway is consistent with a broad range of observed clinical features and biological markers and captures key mediators of pathophysiology. In this proposed pathway, membrane fusion and cytoplasmic entry of SARS-CoV-2 virus via ACE2 and TMPRSS2-expressing respiratory epithelial cells, including pulmonary type-II pneumocytes, provoke an initial immune response featuring inflammatory cytokine production coupled with a weak interferon response, particularly in IFN-λ-dependent epithelial defense...

Neuropeptides synthetised in the enteric nervous system can change the function of the immunocells and play a role in inflammatory processes. In our review the effects of inflammation on the neuropeptide content of nerves and immune cells were compared. Inflamed tissue samples (human gastritis and animal models with experimental colitis and streptozotocin-induced diabetes mellitus) were examined. The number and contacts of neuropeptide-containing nerves and immune cells were studied using immunohistochemistry, confocal laser microscopy and electronmicroscopy...

Objective and Design: Allergic rhinitis (AR) is an immunoglobulin E (IgE)-mediated inflammatory respiratory hypersensitivity characterized by elevated Th2 cytokines and infiltration of inflammatory cells to nasal tissues. BX471 is a small-molecule C-C chemokine receptor type 1 (CCR1) antagonist involved in suppression of inflammation via blocking of primary ligands. In this study, we examined the anti-inflammatory effect of BX471 on ovalbumin (OVA)-induced AR mice model. Materials and Methods: Levels of OVA-specific IgE and Th1 cytokines were determined by enzyme-linked immunosorbent assay (ELISA)...

A 45-year-old man with steroid-dependent ulcerative pancolitis was hospitalized with frequent diarrhea, abdominal pain and distension 3 months after induction of golimumab, a tumor necrosis factor-alpha antagonist. Computed tomography showed wall thickening from the stomach to the colon and massive ascites. Peripheral blood test revealed eosinophilia. A large number of eosinophils were observed in the ascites fluid. Although esophagogastroduodenoscopy showed no abnormal findings and colonoscopy showed ulcerative colitis with a Mayo endoscopic subscore of 1, eosinophil infiltration was histologically observed...

Telmisartan is an angiotensin-II receptor blocker and acts as a selective modulator of peroxisome proliferator-activated receptor gamma (PPARγ). Several studies have demonstrated that telmisartan ameliorates depression and memory dysfunction and reduces brain inflammation. We hypothesized that the beneficial effects of telmisartan on brain could be due to modulation of the blood-brain barrier (BBB) function. Here, we examined the effect of telmisartan on tumor necrosis factor alpha (TNF-α)-induced expression of intercellular adhesion molecule 1 (ICAM-1) which plays an important role in leukocyte transcytosis through the BBB...

Targeted drug approaches have been a major focus for developing new anticancer therapies. Although many such agents approved in the last 20 years have improved outcomes, almost all have underperformed expectations. The full potential of such agents may yet be obtained through novel combinations. Previously, we showed that anti-estrogen drugs combined with a dendritic cell-based anti-HER-2 vaccine known to induce strong Th1-polarized immunity dramatically improved clinical response rates in patients with HER-2pos /ERpos early breast cancer...

Rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) are inflammatory diseases with different bone remodeling patterns. Fibroblast-like synoviocytes (FLS) are cells involved in the transition from an acute and reparable phase to a chronic and persistent stage in these diseases. The distinction of joint phenotypes involves inflammatory cytokines such as tumor necrosis factor alpha (TNF-α), interleukin (IL)-17, and IL-22 directly or through key signaling pathways such as Wnt...

Toll-like receptor 4 (TLR4) recognizes various endogenous and microbial ligands and is an essential part in the innate immune system. TLR4 signaling initiates transcription factor NF-κB and production of proinflammatory cytokines. TLR4 contributes to the development or progression of various diseases including stroke, neuropathic pain, multiple sclerosis, rheumatoid arthritis and cancer, and better therapeutics are currently sought for these conditions. In this study, a library of 140 000 compounds was virtually screened and a resulting hit-list of 1000 compounds was tested using a cellular reporter system...

Corona Virus Disease 2019 (COVID-19) pandemic is rapidly spreading all over the world. Excessive immune responses trigger life-threatening cytokine release syndrome (CRS) which can result in overproduction of pro-inflammatory cytokines including tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), and IL-1β with different pro-inflammatory roles. Anecdotal evidence suggests that the modulation of systemic immune responses may have a potential role in the treatment of patients with COVID-19. Given the importance of the issue and the lack of therapeutic treatment or vaccine; anti-cytokine therapy such as IL-6, TNFα and IL-1 antagonists have been suggested for the alleviation of hyper-inflammation status in these patients...

Acute respiratory distress syndrome (ARDS) is a severe condition with high morbidity and mortality and few interventions. The role of sympathetic stress in the pathogenesis of ARDS has attracted recent research attention. Blockade of alpha-2- or alpha2A-adrenoceptor (α2A-AR) has been shown to attenuate lung injury induced by lipopolysaccharide in rats. However, the mechanism is unclear. We confirmed the role of α2A-AR in ARDS using knockout mice and alveolar macrophages following lipopolysaccharide stimulation to assess the underlying mechanisms...
