Leukotrienes (LTs) are inflammatory mediators produced via the 5-lipoxygenase (5-LO) pathway and are linked to diverse disorders including asthma, allergic rhinitis and cardiovascular diseases. We recently identified the benzimidazole derivative BRP-7 as chemotype for anti-LT agents by virtual screening targeting 5-LO-activating protein (FLAP). Here we aimed to reveal the in ...

Acute inflammation triggered by macrophage infiltration to injured tissue promotes wound repair and may induce pain hypersensitivity. Peroxisome proliferator-activated receptor γ (PPAR)γ signaling is known to regulate heterogeneity of macrophages, which are often referred to as classically activated (M1) and alternatively activated (M2) macrophages. M1 macrophages have considerable antimicrobial activity ...

Persistent pain is a sequela of several neurological conditions with a primary immune basis, such as Guillain-Barré syndrome and multiple sclerosis. Additionally, diverse forms of injury to the peripheral or the central nervous systems--whether traumatic, metabolic, or toxic--result in substantial recruitment and activation of immune cells. This response involves the ...

BACKGROUND: More than 200 primary immune deficiencies have been described. In adults, their identification can be difficult. The lack of timely referrals, diagnostic facilities, and available expertise often delay appropriate treatment. Because an increasing number of adults are now diagnosed with immune deficiencies, there is a need to better understand ...

Let me begin by thanking Kristofor Ellestad (KE) for his open reviewing, for his perceptive, blunt critique and for agreeing to have his analysis published[1].This, in my mind, is how scientific discourse should be conducted. Further the associate editor, Zlatko Dembic, should be complimented for proposing this format.

Lung macrophages are critically involved in respiratory diseases. This study assessed the effects of the PDE4 inhibitor roflumilast and its active metabolite, roflumilast N-oxide on the release of a range of chemokines (CCL2, 3, 4, CXCL1, 8, 10) and of TNF-α, from human lung macrophages, stimulated with bacterial lipopolysaccharide LPS. ...

Infection of the bovine endometrium with Gram-negative bacteria commonly causes uterine disease. Toll-like receptor 4 (TLR4) on cells of the immune system bind Gram-negative bacterial lipopolysaccharide (LPS), stimulating the secretion of the proinflammatory cytokines interleukin 1B (IL1B) and IL6, and the chemokine IL8. Because the endometrium is the first barrier ...

Bronchopulmonary dysplasia (BPD) is characterized by alveolar simplification with decreased alveolar number and increased airspace size. Formation of alveoli involves a process known as secondary septation triggered by myofibroblasts. This study investigated the underlying mechanisms of altered lung morphogenesis in a rat model of BPD induced by intra-amniotic injection of ...

Our previous studies found that 4 compounds, namely pseudohypericin, amentoflavone, quercetin, and chlorogenic acid, in Hypericum perforatum ethanol extract synergistically inhibited lipopolysaccharide (LPS)-induced macrophage production of prostaglandin E2 (PGE2). Microarray studies led us to hypothesize that these compounds inhibited PGE2 production by activating suppressor of cytokine signaling 3 (SOCS3). In ...

Acute liver failure (ALF) is a relatively rare liver disorder that leads to the massive death of hepatocytes. Our previous study has reported that a novel small-molecule agent, (E)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5'-methyl-7,7'-dimethoxy-4,4'-biben-zo[d][1,3]dioxole-5,5'-dicarboxylate (7k), possessed potent anti-inflammatory activity. In the present study, we further evaluated the therapeutic effects of 7k on lipopolysaccharide (LPS)-induced ALF, ...

Pathological conditions and pro-inflammatory stimuli in the brain induce cyclooxygenase-2 (COX-2), a key enzyme in arachidonic acid metabolism mediating the production of prostanoids that, among other actions, have strong vasoactive properties. Although low basal cerebral COX-2 expression has been reported, COX-2 is strongly induced by pro-inflammatory challenges, whereas COX-1 is ...

COPD is a disease of innate immunity and bacterial infections are a dominant cause of exacerbations in the later stages resulting in poor health and high mortality. The pathogen-associated molecular pattern (PAMP) lipopolysaccharide (LPS) is sensed by immune cells through activation of the toll-like receptor 4 (TLR4). This leads to ...

The pathogenesis of sepsis is complex and, unfortunately, poorly understood. The cellular process of autophagy is believed to play a protective role in sepsis; however, the mechanisms responsible for its regulation in this setting are ill defined. In the present study, interferon regulatory factor 1 (IRF-1) was found to regulate ...

The lipopolysaccharide is the major component of Gram-negative bacteria outer membrane. LPS comprises three covalently linked regions: the lipid A, the rough core oligosaccharide, and the O-antigenic side chain determining serotype specificity. Wild-type LPS (sLPS) contains the O-antigenic side chain and is referred to as smooth. Rough LPS (rLPS) does ...

IL-27, which is produced by activated APCs, bridges innate and adaptive immunity by regulating the development of Th cells. Recent evidence supports a role for IL-27 in the activation of monocytic cells in terms of inflammatory responses. Indeed, proinflammatory and anti-inflammatory activities are attributed to IL-27, and IL-27 production itself ...

Aurentiacin is a chalcone isolated from Syzygium samarangense. In the present study, we examined the anti-inflammatory effects of aurentiacin in lipopolysaccharide (LPS)-stimulated mouse macrophages. Aurentiacin significantly inhibited LPS-induced nitric oxide (NO) production in RAW264.7 cells concomitantly with the suppression of inducible nitric oxide synthase (iNOS) expression. Aurentiacin also reduced the ...

Abstract We previously reported that the increment of carbohydrate content in the Viscozyme(®) L (Novozyme Corp., Oklahoma City, OK, USA) extract of Lactobacillus brevis-fermented Ecklonia cava affected the inhibition of nitric oxide (NO) production and that it might be related to the polysaccharide compound. However, there is no report of ...

Background: Although cutaneous and oral lichen planus (LP) share similar histopathological features, oral LP often follows a recalcitrant course while LP skin lesions tend to be self-limiting. Apoptosis, mediated by cytotoxic T-cells in LP, may be triggered by the release of molecules such as perforin and granzyme B. As variation ...

Previous studies of the HLA-B27-transgenic rat model of ankylosing spondylitis (AS) suggested that macrophages develop an intracellular stress response called the unfolded protein response (UPR) and, as a result, secrete increased amounts of cytokines in response to Toll-like receptor agonists such as lipopolysaccharide (LPS). Our objective was to determine whether ...

A large body of evidence suggests that epidermal melanocytes are an integral part of the skin immune system and can be considered immunocompetent cells. Recently, it has been reported that human melanocytes constitutively express Toll-like receptors and may be involved in the induction of several inflammatory cytokines. In the study ...

Acute lung injury (ALI), instilled by lipopolysaccharide (LPS), is a severe illness with excessive mortality and has no specific treatment strategy. Luteolin is an anti-inflammatory flavonoid and widely distributed in the plants. Pretreatment with luteolin inhibited LPS-induced histological changes of ALI and lung tissue edema. In addition, LPS-induced inflammatory responses, ...

Lipopolysaccharide (LPS), an endotoxin of Gram-negative bacteria, activates the innate immunity system through a receptor complex of myeloid differentiation 2 (MD-2) and toll-like receptor 4 (TLR4). MD-2 directly recognizes the lipid A domain of LPS, which triggers MD-2/TLR4-mediated cellular response aimed at eliminating the invaded pathogen. However, excess production of ...

Infection of the cornea with bacteria, viruses, or fungi can result in corneal ulceration. Corneal stromal cells participate in the immune and inflammatory responses to such infection in part by producing various cytokines and chemokines. The effects of lipopolysaccharide (LPS), polyinosinic-polycytidylic acid [poly(I:C)], and zymosan as surrogates for bacteria, viruses, ...
