1. Dietary modulation of peroxisome proliferator-activated receptor gamma.
Match Strength: 4.876

Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor that regulates intestinal inflammation. PPAR gamma is highly expressed in the colon and can be activated by various dietary ligands. A number of fatty acids such as polyunsaturated fatty acids or eicosanoids are considered as endogenous PPAR gamma activators. Nevertheless, other nutrients such as glutamine, spicy food or flavonoids are also able to activate PPAR gamma. As PPAR gamma plays a key role in bacterial induced inflammation, anti-inflammatory properties of probiotics may be mediated through PPAR gamma. ... Read More »

2. Role of local pulmonary IFN-gamma expression in murine allergic airway inflammation.
Match Strength: 4.655

Generalized underrepresentation of IFN-gamma has been implicated in the development of allergic asthma. However, the role of local IFN-gamma in the lung during the development of this disease has not been completely elucidated. We studied the influence of local pulmonary IFN-gamma expression on the development of allergen-induced lung inflammation. To restrict our analysis to IFN-gamma expression in the lung and to exclude influences of systemic IFN-gamma production, we generated a transgenic mouse line with a targeted deletion of the IFN-gamma gene and constitutive, lung-specific IFN-gamma ... Read More »

3. IFN-gamma-producing human T cells directly induce osteoclastogenesis from human monocytes via the expression of RANKL.
Match Strength: 4.643

The current study explored our hypothesis that IFN-gamma-producing human T cells inhibit human osteoclast formation. Activated T cells derived from human PBMC were divided into IFN-gamma-producing T cells (IFN-gamma(+) T cells) and IFN-gamma-non-producing T cells (IFN-gamma(-) T cells). IFN-gamma(+) T cells were cultured with human monocytes in the presence of macrophage-CSF alone. The concentration of soluble receptor activator of NF-kappaB ligand (RANKL) and IFN-gamma, and the amount of membrane type RANKL expressed on T cells, were measured by ELISA. In the patients with early rheumatoid ... Read More »

4. Interferon-gamma and atherosclerosis: pro- or anti-atherogenic?
Match Strength: 4.609

Atherosclerosis is considered to be a form of chronic inflammation governed by a complex network of inter- and intra-cellular signaling pathways. The pleiotropic cytokine interferon-gamma (IFN-gamma) is a key pro-inflammatory mediator that is expressed at high levels in atherosclerotic lesions. IFN-gamma regulates the function and properties of all the cell types in the vessel wall. The precise role of IFN-gamma in atherogenesis is complex, with both pro- and anti-atherogenic actions being identified. This review will discuss these actions of the cytokine along with recent findings that have ... Read More »

5. A spectroscopic study of the inclusion of azulene by beta- and gamma-cyclodextrins.
Match Strength: 4.575

The inclusion of azulene (AZ) inside the cavities of beta-cyclodextrin (beta-CD) and gamma-cyclodextrin (gamma-CD) was studied using absorption, fluorescence and induced-circular dichroism spectroscopy. The inclusion of AZ into the cavity of beta-CD has a stoichiometry of 1:1, whereas that of AZ/gamma-CD complex is 1:2. The equilibrium constants for the formation of the two complexes were calculated to be 780+/-150 M(-1) for AZ:beta-CD and (4.5+/-0.86)x10(5) M(-2) for AZ:(gamma-CD)(2). The latter is due to a stepwise equilibrium mechanism in which a 1:1 complex is formed with a binding ... Read More »

6. How interferon-gamma keeps autoimmune diseases in check.
Match Strength: 4.552

Interferon-gamma (IFN-gamma) is regarded traditionally as a proinflammatory factor and as the signature cytokine of Th1-dominated autoimmune processes. Early evidence indicative of an opposite, protective role has recently received further attention from reports revealing an increasing number of pathways by which IFN-gamma can counteract harmful inflammation in Th1-associated autoimmune diseases. Here, we review evidence for IFN-gamma's anti-inflammatory effects primarily from the perspective of one experimental model, collagen-induced arthritis (CIA), and question the classic proinflammatory ... Read More »

7. Does gamma-tocopherol play a role in the primary prevention of heart disease and cancer? A review.
Match Strength: 4.491

Vitamin E consists of a group of eight isomers, four tocopherols (alpha-, beta-, gamma-, delta-tocopherol) and four tocotrienols (alpha-, beta-, gamma-, delta-tocotrienol). While extensive literature has been published on the potential health benefits of alpha-tocopherol, little is known about gamma-tocopherol, the major form of vitamin E in food in the U.S. gamma-tocopherol has recently received more research attention based on findings from in vitro and animal studies indicating that it has potent anti-inflammatory and antioxidant properties. Based on these recent studies, it is important to ... Read More »

8. Influence of IFN-gamma on gene expression in normal human bronchial epithelial cells: modulation of IFN-gamma effects by dexamethasone.
Match Strength: 4.474

Interferon gamma (IFN-gamma) plays a role in a variety of lung inflammatory responses, and corticosteroids are frequently employed as a treatment in these conditions. Therefore, the effect of IFN-gamma, of the corticosteroid dexamethasone (Dex), or of both on gene expression was studied in normal human bronchial epithelial (NHBE) cells. NHBE cells were exposed to medium alone, IFN-gamma (300 U/ml), Dex (10(-7) M), or both IFN-gamma and Dex for 8 or 24 h. Gene expression was examined using oligonucleotide microarrays. A principal components analysis demonstrated that the IFN-gamma treatment ... Read More »

9. Peroxisome proliferator-activated receptor-gamma ligands as bone turnover modulators.
Match Strength: 4.437

PPAR-gamma ligands are being used for the treatment of human metabolic disorders; they also exert anti-inflammatory and antineoplastic properties that are now being explored in clinical studies. Recent data have further extended the crucial role of PPAR-gamma and its ligands in bone turnover. This review summarises the latest knowledge of the expression of PPAR-gamma in bone tissue and the regulatory effect of diverse synthetic and natural PPAR-gamma ligands on bone formation and resorption. Taking into account the data so far, PPAR-gamma ligands seem to be able to contribute to the treatment ... Read More »

10. Abeta 11-40/42 production without gamma-secretase epsilon-site cleavage.
Match Strength: 4.367

The accumulation and deposition of fibrillar Abeta is thought to be the primary cause of Alzheimer's disease. Abeta is derived from Alzheimer amyloid precursor protein (APP) by sequential proteolytic cleavage involving beta- and gamma-secretase. Recently, gamma-secretase was shown to cleave near the cytoplasmic membrane boundary of APP (called the epsilon-cleavage), as well as in the middle of the membrane domain (gamma-cleavage). It has been reported that the C-terminus of Abeta is generated via a series of sequential cleavages, epsilon-cleavage followed by gamma-cleavage. However, recent ... Read More »

11. FcgammaRIII-dependent inhibition of interferon-gamma responses mediates suppressive effects of intravenous immune globulin.
Match Strength: 4.337

Intravenous immune globulin (IVIG) suppresses autoantibody-mediated inflammation by inducing and activating the inhibitory Fc receptor FcgammaRIIb and downstream negative signaling pathways. We investigated the effects of IVIG on cellular responses to interferon-gamma (IFN-gamma), a potent macrophage activator that exacerbates inflammation. Our study showed that IVIG blocked IFN-gamma signaling and IFN-gamma-induced gene expression and suppressed IFN-gamma function in vivo during immune responses to Listeria monocytogenes and in an IFN-gamma-enhanced model of immune thrombocytopenic purpura. ... Read More »

12. Mutual antagonistic relationship between prostaglandin E(2) and IFN-gamma: Implications for rheumatoid arthritis.
Match Strength: 4.310

Prostaglandin E(2) (PGE(2)) is a major mediator of inflammation and is present at high concentrations in the synovial fluid of rheumatoid arthritis (RA) patients. PGE(2), acting through the EP4 receptor, has both pro- and anti-inflammatory roles in vivo. To shed light on this dual role of PGE(2), we investigated its effects in whole blood and in primary human fibroblast-like synoviocytes (FLS). Gene expression analysis in human leukocytes, confirmed at the protein level, revealed an EP4-dependent inhibition of the expression of genes involved in the IFN-gamma-activation pathway, including IFN ... Read More »

13. Scaffold of the cyclooxygenase-2 (COX-2) inhibitor carprofen provides Alzheimer gamma-secretase modulators.
Match Strength: 4.271

N-sulfonylated and N-alkylated carprofen derivatives were investigated for their inhibition and modulation of gamma-secretase, which is associated with Alzheimer's disease. The introduction of a lipophilic substituent transformed the COX-2 inhibitor carprofen into a potent gamma-secretase modulator. Several compounds (e.g., 9p, 11f) caused selective reduction of Abeta42 and an increase of Abeta38. The most active compounds displayed activities in the low micromolar range and no effect on the gamma-secretase cleavage at the e-site ... Read More »

14. Inhibition of inflammation and carcinogenesis in the lung and colon by tocopherols.
Match Strength: 4.263

Tocopherols, which exist in alpha, beta, gamma, and delta forms, are antioxidative nutrients also known as vitamin E. Although alpha-tocopherol (alpha-T) is the major form of vitamin E found in the blood and tissues, gamma- and delta-T have been suggested to have stronger anti-inflammatory activities. In the present study, using a tocopherol mixture that is rich in gamma-T (gamma-TmT, which contains 57%gamma-T), we demonstrated the inhibition of inflammation as well as of cancer formation and growth in the lung and colon in animal models. When given in the diet at 0.3%, gamma-TmT inhibited ... Read More »

15. Narrowing in on cardiovascular disease: the atheroprotective role of peroxisome proliferator-activated receptor gamma.
Match Strength: 4.247

Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor that has been suggested to play protective roles in the pathogenesis of diseases that are characterized by chronic inflammation, such as atherosclerosis. The study of nuclear receptors, including PPAR gamma, has led to the discovery of anti-inflammatory processes that are collectively known as transrepression. In this review, we will highlight some of the mechanisms of PPAR gamma-mediated transrepression that have surfaced throughout the past decade. We will also discuss the existing evidence for an ... Read More »

16. Interferon gamma: a master regulator of atherosclerosis.
Match Strength: 4.233

Atherosclerosis is a chronic inflammatory disease that is characterized by the development of fibrotic plaques in the arterial wall. The disease exhibits a complex aetiology and its progression is influenced by a number of environmental and genetic risk factors. The cytokine interferon-gamma (IFN-gamma), a key regulator of immune function, is highly expressed in atherosclerotic lesions and has emerged as a significant factor in atherogenesis. Evidence from both mouse models of atherosclerosis and in vitro cell culture has suggested that the role of IFN-gamma is complex since both pro- and anti ... Read More »

17. 1H-NMR study of the inclusion processes for alpha- and gamma-cyclodextrin with fenbufen.
Match Strength: 4.219

1H-NMR spectra of aqueous solutions of fenbufen and two cyclodextrins (alpha- or gamma-cyclodextrin, respectively) mixtures confirm the formation of an inclusion complex if gamma-cyclodextrin is used, whereas in the case of alpha-cyclodextrin no inclusion complex was obtained. The stoichiometry of the fenbufen/gamma-cyclodextrin complex is of the [2:1] type. The geometry of this supramolecular architecture was established through MM+ molecular mechanics calculations ... Read More »

18. In vitro restoration of post-operatively decreased IFN-gamma levels after cardiac surgery and its effect on pro- and anti-inflammatory mediators.
Match Strength: 4.207

BACKGROUND: A decreased synthesis of interferon gamma (IFN-gamma) by TH 1 lymphocytes after cardiac operations with cardiopulmonary bypass (CPB) is part of the inflammatory response to local operative and systemic traumas. The consequences of this mechanism on the release of pro- and anti-inflammatory cytokines remain unclear. To evaluate the role of IFN-gamma, we added recombinant IFN-gamma to peripheral blood mononuclear cells (PBMCs) on the first post-operative day in an attempt to restore pre-operative values and then measured the release of pro- and anti-inflammatory cytokines in vitro. ... Read More »

19. Preferential T(h)2 polarization by OCH is supported by incompetent NKT cell induction of CD40L and following production of inflammatory cytokines by bystander cells in vivo.
Match Strength: 4.205

The altered glycolipid ligand OCH is a selective inducer of T(h)2 cytokines from NKT cells and a potent therapeutic reagent for T(h)1-mediated autoimmune diseases. Although we have previously shown the intrinsic molecular mechanism of preferential IL-4 production by OCH-stimulated NKT cells, little is known about the extrinsic regulatory network for IFN-gamma production. Here we demonstrate that OCH induces lower production of IFN-gamma, not only by NKT cells but also by NK cells compared with alpha-galactosylceramide. OCH induced lower IL-12 production due to ineffective primary IFN-gamma and ... Read More »

20. How an increased intake of alpha-tocopherol can suppress the bioavailability of gamma-tocopherol.
Match Strength: 4.199

alpha-Tocopherol is the only form of vitamin E in vitamin supplements, whereas gamma-tocopherol is the predominant form of vitamin E in the US diet. gamma-Tocopherol has beneficial properties as an anti-inflammatory and possibly anti-atherogenic and anticancer agent. Excess a-tocopherol taken in supplements causes a reduction of gamma-tocopherol concentration in plasma. The biochemical mechanism of this effect, which is important to human nutrition, has recently been elucidated ... Read More »
