Inflammatory cytokines

Resveratrol is a naturally occurring compound with anti-inflammatory properties. However, the protective molecular mechanisms of resveratrol against LPS-induced inflammation have not been thoroughly known. In the present study, we examined the antiinflammatory effect of resveratrol in inflammatory model using murine macrophage-like cell RAW264.7 stimulated with LPS. Resveratrol suppressed the production of inflammatory cytokines in LPS-stimulated RAW264.7 cells with the IC50 value as 17.5 ± 0.7 μM for IL-6, 14.2 ± 1.9 μM for IL-10, and 18.9 ± 0.6 μM for TNF-α.

Regulator of G-protein signaling (RGS) proteins were originally identified as negative regulators of G-protein-coupled receptor (GPCR) signaling via their GTPase-accelerating protein (GAP) activity. All RGS proteins contain evolutionarily conserved RGS domain; however, they differ in their size and regulatory domains. RGS1 and RGS10 are smaller than other RGS proteins, and their functions involve various inflammatory responses including autoimmune responses in both the periphery and the central nervous system (CNS). Neuroinflammation is the chronic inflammatory response in the CNS.

The Goodpasture antigen-binding protein, GPBP, is a serine⁄threonine kinase whose relative expression increases in autoimmune processes. Tumor necrosis factor (TNF) is a pro-inflammatory cytokine implicated in auto-immune pathogenesis. Here we show that COL4A3BP, the gene encoding GPBP, maps head-to-head withPOLK, the gene encoding for DNA polymerase kappa (polj), and shares with it a 140-bp promoter containing a Sp1 site, a TATA-like element, and a nuclear factor kappa B (NFjB)-like site

Peripheral nerve injury is normally followed by a robust regenerative response. Here we describe the early changes associated with injury from the initial rise in intracellular calcium and the subsequent activation of transcription factors and cytokines leading to an inflammatory reaction, and the expression of growth factors, cytokines, neuropeptides, and other secreted molecules involved in cell-to-cell communication promoting regen-eration and neurite outgrowth.

Cyclooxygenase-2 (COX-2) is a key enzyme in the production of prosta-glandins that are major inflammatory agents. COX-2 production is trig-gered by exposure to various cytokines and to bacterial endotoxins. We present here a novel role for the Ets transcription factor ESE-1 in regula-ting the COX-2gene in response to endotoxin and other pro-inflammatory stimuli. We report that the induction of COX-2expression by lipopoly-saccharide (LPS) and pro-inflammatory cytokines correlates with ESE-1 induction in monocyte⁄macrophages. ...

The transcription factor nuclear factorjB(NF-jB) is an activator of multiple cytokines, chemokines and adhesion molecules, which are important in inflammatory diseases such as asthma, and is consequently considered as an attractive therapeutic target. In the present study, a con-stitutively active dominant version of IjBa,IjBaDN, was introduced into A549 pulmonary cells by adenovirus-mediated delivery. The dominant IjB, but not a null viral vector, prevented the induction of NF-jB-dependent transcription by both tumor necrosis factora(TNFa)and interleukin-1b(IL-1b). ...

The macrophage is critical to the innate immune response and contributes to human diseases, including inflammatory arthritis and plaque formation in atherosclerosis. Vascular endothelial growth factor (VEGF) is an angio-genic cytokine that is produced by macrophages.

Lipopolysaccharide is a major constituent of the outer membrane of Gram-negative bacteria. It activates monocytes and macrophages to produce cytokines such as tumor necrosis factor-aand interleukins IL-1b and IL-6. These cytokines appear to be responsible for the neurotoxicity observed in peripheral nervous system inflammatory disease.

Matrix metalloproteinase-9 (MMP-9) displays a preference for a broad range of substrates including extracellular matrix proteins and cytokines. MMP-9 plays an important role in physiological processes, as well as in inflammatory diseases and numerous cancers.

Tumour necrosis factor-a(TNF-a) is a cytokine that is involved in many functions, including the inflammatory response, immunity and apoptosis. Some of the responses of TNF-a are mediated by caspase-1, which is involved in the production of the pro-inflammatory cytokines interleukin-1b, interleukin-18 and interleukin-33.

It has been well documented that both endogenous inflammatory mediator advanced glycation end products (AGEs) and exogenous inflammatory inducer lipopolysaccharide play key roles in the initiation and development of inflammatory diseases. However, the combined inflammation-stimulatory effect of AGEs and lipopolysaccharide on endothelial cells, and, further-more, the underlying signal transduction pathways involved, have not been fully elucidated.

The regulation of cytokines and pro-inflammatory genes is an absolute essentiality to combat inflammatory diseases. The present study investigated the effects of 4-O-chloroacetyl-2,3-di-O-acetyl-6-O-levulinoyl-b-d-glucopyr-anosyl]-(1-3)-1-O-(p-methoxyphenyl)-2-deoxy-2-N-trichloroacetyl-4,6-O-ben-zylidene-a-d-glucopyranoside (RSCL-0409), a novel small molecule Toll-like receptor (TLR) signalling antagonist, and its mechanism of action in human monocytic (THP-1) cells stimulated with lipopolysaccharide (LPS)....

The human guanylate binding protein 5 (hGBP5) belongs to the family of interferon-c-inducible large GTPases, which are well known for their high induction by pro-inflammatory cytokines. The cellular role of this protein family is unclear at this point, but there are indications for antiviral and antibacterial activity of hGBP1.

Human guanylate-binding protein 1 (hGBP1) belongs to the superfamily of large, dynamin-related GTPases. The expression of hGBP1 is induced by stimulation with interferons (mainly interferon-c), and it plays a role in dif-ferent cellular responses to inflammatory cytokines, e.g. pathogen defence, control of proliferation, and angiogenesis.
