BACKGROUND/AIMS: Serum procalcitonin (PCT) is elevated in acute liver failure (ALF), but the expression of PCT in the liver has not been elucidated. We aimed to clarify the regulation of hepatic PCT expression and the cell sources in ALF. METHODS: Human monocytic leukemia line U937 cells were treated with 12-O-tetradecanoylphorbol-l3-acetate (PMA) (100 ng/ mL) for 24 h to induce activated macrophages. In the presence of lipopolysaccharide (LPS, 1 μg/mL), activated macrophages and human hepatocyte line L02 cells were incubated with LPS or co-cultured for 0, 2, 6, and 24 h...

Plants and natural molecules are generally consumed not in raw state but after different processing conditions (heating, mechanical agitation or cooking). The understanding of the chemistry and biological outcome of thermal treatment is still scarce. In the current study, Eriodictyol, a natural flavanone, has undergone heat treatment, generating hence three different products ((3-(3,4-dihydroxyphenyl)-3-hydroxypropanoic acid, (3-(3,4-dihydroxyphenyl) propanal) and an unidentified component). The consequences of aforementioned treatment on the immunomodulatory behavior of resulted molecules were evaluated...

Mucosa associated lymphoid tissue lymphoma translocation protein 1 (MALT1) is not only an intracellular signaling scaffold protein but also a paracaspase that plays a key role in the signal transduction and cellular activation of lymphocytes and macrophages. However, its role in endothelial cells remains unknown. Here we report that pharmacological inhibition of MALT1 protease activity strongly suppresses endothelial activation via enhancing MCPIP1 expression. Treatment with MALT1 protease inhibitors selectively inhibited TNFα-induced VCAM-1 expression in HUVECs and LPS-induced VCAM-1 expression in mice...

Neuromyelitis optica spectrum disorders (NMOSD) are a group of autoimmune astrocytopathies in the central nervous system, which are mainly caused by immunoglobulin G (IgG) against astrocyte water channel aquaporin-4 (AQP4). In this study, we aimed to establish a model of NMOSD-related optic neuritis (NMOSD-ON) and to evaluate the progressive changes of the optic nerve and visual function. AQP4 IgG-positive serum from NMOSD patients was injected into the subarachnoid space of the rat optic nerve to induce the NMOSD-ON model (AQP4 + group), and healthy serum was injected as the control...

Acute lung injury (ALI) is an acute failure of the respiratory system with unacceptably high mortality, for which effective treatment is urgently necessary. Infiltrations by immune cells, such as leukocytes and macrophages, are responsible for the inflammatory response in ALI, which is characterized by excessive production of pro-inflammatory mediators in lung tissues exposed to various pathogen-associated molecules such as lipopolysaccharide (LPS) from microbial organisms. α-Ketoglutarate (α-KG) is a key metabolic intermediate and acts as a pro-inflammatory metabolite, which is responsible for LPS-induced proinflammatory cytokine production through NF-κB signaling pathway...

Macrophages are among the main cells involved in generation of inflammation. To investigate the anti-inflammatory effect of Satureja hortensis (summer savory), lipopolysaccharide (LPS)-activated J774.1 macrophages were treated with various extracts, and the expression and release of various inflammatory molecules by macrophages were examined. We showed that dichloromethane and hexane extracts reduced nitric oxide (NO) production more efficiently than other extracts. Both extracts decreased gene expression of inducible NO synthase (iNOS) (<0...

While immunomodulatory monoclonal antibodies (mAbs) have therapeutic efficacy against many tumors, few patients are cured. Attempting to improve their therapeutic efficacy we have applied the TC1 mouse lung carcinoma model and injected established subcutaneous tumors intratumorally with 3 weekly doses of various combinations of mAbs. Combinations of mAbs to CTLA4/PD1/CD137 (the 3 mAb combination) and to CTLA4/PD1/CD137/CD19 (the 4 mAb combination) were most efficacious to induce complete regression of both the injected tumor and an untreated tumor in the same mouse...

PURPOSE: Previous investigations revealed influences of irradiation up to 2.0 Gy on the cytokine secretion profile of inflammatory, peritoneal mouse macrophages (pMФ). This raised the question if those alterations impact on dendritic cells and consecutive T-cell responses. Further, the impact of irradiation directly on pMФ capacity to induce T-cell responses was analyzed. MATERIALS AND METHODS: pMФ were LPS-activated, irradiated and the expression of activation markers was assessed...

A number of bacteria provoking zoonotic diseases present intracellular survival and a host cell tropism limited to the monocyte/macrophage lineage. Thus, infection is rendered difficult to eradicate, causing chronic inflammatory reactions to the host and widespread prevalence. Although self-inactivating lentiviral vectors have been successfully tested in the clinic against virally-induced human infectious diseases, little is known about the transduction susceptibility of ruminant animal phagocytes that play a critical role in the outbreak of zoonotic diseases such as brucellosis...

Chinotto ( Citrus myrtifolia Raf.) is a widely diffused plant native from China and its fruits have a wide-spread use in confectionary and drinks. Remarkably, only little has been reported thus far on its bioactive properties, in contrast to those of the taxonomically related bergamot ( Citrus bergamia Risso). The present study aimed to investigate potential in vitro anti-inflammatory and radical scavenging properties of chinotto essential oils (CEOs) and to establish to what extent their composition and bioactivities are dependent on maturation...

Aims Lumbar radicular pain after disc herniation may be associated release of pro-inflammatory cytokines from nucleus pulposus (NP) tissue. In the present study we examined the role of interferon-γ (IFN-γ) and cluster of differentiation 68 (CD68) in the acute phase of this process. Methods First, in an animal model mimicking the clinical situation after disc herniation, the role of IFN-γ on the dorsal horn single cell activity and gene expression close to the nerve roots was studied. Second, in patients with severe lumbar radicular pain due to disc herniation, we examined how two single nucleotide polymorphisms (SNPs; rs2069705 and rs2069718) important for the IFN-γ expression influenced the pain and disability measured by visual analogue scale (VAS) and Oswestry Disability Index (ODI)...

Background It is unknown why an acute pain condition under various circumstances can transition into a chronic pain condition. There has been a shift towards neuroinflammation and hence glial cell activations specifically in the dorsal root ganglion and spinal cord as a mechanism possibly driving the transition to chronic pain. This has led to a focus on non-neuronal cells in the peripheral and central nervous system. Besides infiltrating macrophages, Schwann cells and satellite glial cells release cytokines and therefore important mechanisms in the maintenance of pain...

In our previous work, we showed that during inflammation-induced epithelial-to-mesenchymal transition (EMT), mesenteric mesothelial cells express ED1 (pan-macrophage marker), indicating that they are transformed into macrophage-like cells. In this paper, we provide additional evidences about this transition by following the phagocytic activity and the TNFα production of mesenteric mesothelial cells during inflammation. Upon injection of India ink particles or fluorescent-labeled bioparticles (pHrodo) into the peritoneal cavity of rats pretreated with Freund's adjuvant, we found that mesothelial cells efficiently engulfed these particles...

Pericarditis is an inflammatory heart disease, which may be idiopathic or secondary to autoimmune or auto-inflammatory diseases and often leads to severe or life-threatening complications. Colchicine and non-steroidal anti-inflammatory drugs represent the mainstay of treatment, whereas use of corticosteroids is associated with recurrence of disease flares. While effective and safe anti-inflammatory therapies remain an unmet clinical need, emerging clinical and experimental evidence points at a promising role of inhibition of the pro-inflammatory cytokine interleukin-1 (IL-1)...
