Statins are mainstream therapy in the treatment and prevention of cardiovascular disease through inhibitory effects on cholesterol synthesis. However, statins' beneficial effects in cardiovascular disease may also be attributable to their role as anti-inflammatory mediators. Here, we investigated the effects of simvastatin treatment on expression levels of interleukin (IL) 1β in both patient with hyperlipidemia and healthy human peripheral blood mononuclear cells (PBMCs) using cholesterol crystals (CC), a cardiovascular pathogenic stimulus for activation of the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome...

The Salicornia europaea L. (SE) plant is a halophyte that has been widely consumed as a seasoned vegetable, and it has been recently reported to counteract chronic diseases related to oxidative and inflammatory stress. In this study, we performed an initial phytochemical analysis with in vitro biochemical tests and chromatographic profiling of desalted and enzyme-digested SE ethanol extract (SE-EE). Subsequently, we evaluated the anti-neuroinflammatory and ameliorative potential of SE-EE in LPS-inflicted BV-2 microglial cells and scopolamine-induced amnesic C57/BL6N mice, respectively...

Topical corticosteroids are effective anti-inflammatory drugs in the treatment of anterior uveitis. The intraocular efficacy of topical corticosteroids mostly depends on their intraocular permeability through the cornea. Lipophile derivatives such as dexamethasone and prednisolone acetate penetrate better into the anterior chamber than hydrophilic derivatives. Prednisolone acetate 1% is the first choice in the therapy of patients with anterior uveitis. Loteprednole and fluorometholone have a slightly weaker anti-inflammatory effect, but they induce less elevation of intraocular pressure and might be helpful in the treatment of patients with steroid response...

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for inflammation control and pain relief. However, while the adjunct use of NSAIDs is avoided for periodontal therapy because of related side effects, cyclic administration of NSAIDs may reduce or eliminate these effects. We evaluated the effect of a cyclic diclofenac potassium (DP) regimen on clinical parameters and levels of prostaglandin E2 (PGE2 ) and interleukin-1β (IL-1β) in the gingival crevicular fluid (GCF) of individuals with periodontitis...

BACKGROUND: Rheumatoid arthritis (RA) preferentially affects women, with the peak incidence coinciding with estrogen decrease in menopause. Estrogen (E2) may therefore have intrinsic immune-regulatory properties that vanish with menopause. Fc sialylation is a crucial factor determining the inflammatory effector function of antibodies. We therefore analyzed whether E2 affects immunoglobulin G (IgG) sialylation. METHODS: Postmenopausal (ovariectomized) mice were immunized with ovalbumin and treated with E2 or vehicle...

Background: Anti-tumor necrosis factor (TNF) therapy appears to be effective in the treatment of Crohn's disease (CD), a chronic inflammatory disease of the gastrointestinal tract. However, the mechanisms involved are not completely understood. Methods: Fifty-seven active CD patients were enrolled, and cytokine profiles in colonic biopsies of patients with active CD receiving anti-TNF monoclonal antibody (mAb) (infliximab [IFX]) treatment were determined using quantitative real-time polymerase chain reaction (qRT-PCR)...

Inhibition of heme oxygenase-1 (HO-1, encoded by HMOX1), a cytoprotective, anti-apoptotic and anti-inflammatory enzyme, may serve as a valuable therapy in various pathophysiological processes, including tumorigenesis. We compared the effect of chemical inhibitors - metalloporphyrins, with genetic tools - shRNA and CRISPR/Cas9 systems, to knock-down (KD)/knock-out (KO) HO-1 expression/activity. 293T cells were incubated with metalloporphyrins, tin and zinc protoporphyrins (SnPPIX and ZnPPIX, respectively) or were either transduced with lentiviral vectors encoding different shRNA sequences against HO-1 or were modified by CRISPR/Cas9 system targeting HMOX1...

Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase (COX) activity and are commonly used for pain relief and fever reduction. NSAIDs are used following childhood vaccinations and cancer immunotherapies; however, how NSAIDs influence the development of immunity following these therapies is unknown. We hypothesized that NSAIDs would modulate the development of an immune response to Listeria monocytogenes -based immunotherapy. Treatment of mice with the nonspecific COX inhibitor indomethacin impaired the generation of cell-mediated immunity...

Neurodegeneration is a progressive loss of neuronal cells in certain regions of the brain. Most of the neurodegenerative disorders (NDDs) share the communal characteristic such as damage or reduction of various cell types typically including astrocytes and microglial activity. Several compounds are being trialed to treat NDDs but they possess solitary symptomatic advantages along with copious side effects. The finding of more enthralling and captivating compounds to suspend and standstill the pathology of NDDs will be considered as a hallmark of present times...

Recent studies have demonstrated that inhibition of p38α MAP kinase could effectively inhibit pro-inflammatory cytokines including TNF-α and interleukins. Thus, inhibition of this enzyme can prove greatly beneficial in the therapy of chronic inflammatory diseases. A new series of N-[3-(substituted-4H-1,2,4-triazol-4-yl)]-benzo[d]thiazol-2-amines (4a-n) were synthesized and subjected to in vitro evaluation for anti-inflammatory activity (BSA anti-denaturation assay) and p38α MAPK inhibition. Among the compounds selected for in vivo screening of anti-inflammatory activity (4b, 4c, 4f, 4g, 4j, 4m, and 4n), compound 4f was found to be the most active with an in vivo anti-inflammatory efficacy of 85...

Chronic inflammation plays an essential role in the development of diabetic complications. Understanding the molecular mechanisms that support inflammation is a prerequisite for the design of novel anti-inflammatory therapies. These would take into consideration circulating levels of cytokines and damage-associated molecular patterns (DAMPs) that include the high mobility group box 1 (HMGB1) protein which, in part, promotes the inflammatory response through TLR4 signaling. The liver, as the source of circulating cytokines and acute-phase proteins, contributes to the control of systemic inflammation...

Obesity is a state of chronic inflammation influenced by lipids such as fatty acids and their secondary oxygenated metabolites deemed oxylipids. Many such lipid mediators serve as potent signaling molecules of inflammation, which can further alter lipid metabolism and lead to carcinogenesis. For example, sphingosine-1-phosphate activates cyclooxygenase-2 in endothelial cells resulting in the conversion of arachidonic acid (AA) to prostaglandin E2 (PGE2 ). PGE2 promotes colon cancer cell growth. In contrast, the less studied path of AA oxygenation via cytochrome p450 enzymes produces epoxyeicosatetraenoic acids (EETs), whose anti-inflammatory properties cause shrinking of enlarged adipocytes, a characteristic of obesity, through the liberation of fatty acids...

Severe demyelinating disorders of the central nervous system (CNS) such as multiple sclerosis (MS), can be devastating for many young lives. To date, the factors resulting in poor remyelination and repair are not well understood, and reparative therapies that benefit MS patients have yet to be developed. We have previously shown that the activity and abundance of Lipoprotein Lipase (LPL)-the rate-limiting enzyme in the hydrolysis of triglyceride-rich lipoproteins-is increased in Schwann cells and macrophages following nerve crush injury in the peripheral nervous system (PNS), suggesting that LPL may help scavenge myelin-derived lipids...

Tumor necrosis factor (TNF) antagonists are popular therapies for inflammatory diseases. These agents enhance numbers and function of regulatory T cells (Tregs) which are important in controlling inflammatory diseases. However, elevated Tregs increase susceptibility to infections, including histoplasmosis. We determined the mechanism by which Tregs expand in TNF-neutralized mice infected with Histoplasma capsulatum Lung CD11c+ CD11b+ dendritic cells (DC), but not alveolar macrophages, from H. capsulatum -infected mice treated with anti-TNF induced a higher percentage of Tregs than control DC in vitro...

BACKGROUND: Previous preclinical evidence has suggested that the elevation of epoxyeicosatrienoic acids (EETs) derived from the cytochrome P450 (CYP) epoxygenases-dependent metabolism of arachidonic acid has important anti-inflammatory effects. However, the levels of EETs and their synthetic and metabolic enzymes in human ulcerative colitis has not been evaluated. METHOD: To evaluate EETs and the expression of relevant CYP isoforms and the metabolizing enzyme, soluble epoxide hydrolase (sEH), tissue biopsies were collected from 16 pairs of ulcerative colitis patients' tissues and matched with adjacent non-inflamed tissues...
