Sweet taste receptor agonists attenuate macrophage IL-1β expression and eosinophilic inflammation linked to autophagy deficiency in myeloid cells. Clin Transl Med 2022; 12:e1021. [PMID: 35988262 PMCID: PMC9393075 DOI: 10.1002/ctm2.1021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Revised: 06/28/2022] [Accepted: 08/04/2022] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND Eosinophilic inflammation is a hallmark of refractory chronic rhinosinusitis (CRS) and considered a major therapeutic target. Autophagy deficiency in myeloid cells plays a causal role in eosinophilic CRS (ECRS) via macrophage IL-1β overproduction, thereby suggesting autophagy regulation as a potential therapeutic modality. Trehalose is a disaccharide sugar with known pro-autophagy activity and effective in alleviating diverse inflammatory diseases. We sought to investigate the therapeutic potential of autophagy-enhancing agent, trehalose, or related sugar compounds, and the underlying mechanism focusing on macrophage IL-1β production in ECRS pathogenesis. METHODS We investigated the therapeutic effects of trehalose and saccharin on macrophage IL-1β production and eosinophilia in the mouse model of ECRS with myeloid cell-specific autophagy-related gene 7 (Atg7) deletion. The mechanisms underlying their anti-inflammatory effects were assessed using specific inhibitor, genetic knockdown or knockout, and overexpression of cognate receptors. RESULTS Unexpectedly, trehalose significantly attenuated eosinophilia and disease pathogenesis in ECRS mice caused by autophagy deficiency in myeloid cells. This autophagy-independent effect was associated with reduced macrophage IL-1β expression. Various sugars recapitulated the anti-inflammatory effect of trehalose, and saccharin was particularly effective amongst other sugars. The mechanistic study revealed an involvement of sweet taste receptor (STR), especially T1R3, in alleviating macrophage IL-1β production and eosinophilia in CRS, which was supported by genetic depletion of T1R3 or overexpression of T1R2/T1R3 in macrophages and treatment with the T1R3 antagonist gurmarin. CONCLUSION Our results revealed a previously unappreciated anti-inflammatory effect of STR agonists, particularly trehalose and saccharin, and may provide an alternative strategy to autophagy modulation in the ECRS treatment.

Abstract
Background Ginsenosides have beneficial effects on several airway inflammatory disorders primarily through glucocorticosteroid-like anti-inflammatory activity. Among inflammatory cells, eosinophils play a major pathogenic role in conferring a risk of severe refractory diseases including chronic rhinosinusitis (CRS). However, the role of ginsenosides in reducing eosinophilic inflammation and CRS pathogenesis is unexplored. Methods We investigated the therapeutic efficacy and underlying mechanism of ginsenoside F1 (G-F1) in comparison with those of dexamethasone, a representative glucocorticosteroid, in a murine model of CRS. The effects of G-F1 or dexamethasone on sinonasal abnormalities and infiltration of eosinophils and mast cells were evaluated by histological analyses. The changes in inflammatory cytokine levels in sinonasal tissues, macrophages, and NK cells were assessed by qPCR, ELISA, and immunohistochemistry. Results We found that G-F1 significantly attenuated eosinophilic inflammation, mast cell infiltration, epithelial hyperplasia, and mucosal thickening in the sinonasal mucosa of CRS mice. Moreover, G-F1 reduced the expression of IL-4 and IL-13, as well as hematopoietic prostaglandin D synthase required for prostaglandin D2 production. This therapeutic efficacy was associated with increased NK cell function, without suppression of macrophage inflammatory responses. In comparison, dexamethasone potently suppressed macrophage activation. NK cell depletion nullified the therapeutic effects of G-F1, but not dexamethasone, in CRS mice, supporting a causal link between G-F1 and NK cell activity. Conclusion Our results suggest that potentiating NK cell activity, for example with G-F1, is a promising strategy for resolving eosinophilic inflammation in CRS.

J Allergy Clin Immunol 2017; 141:938-950.e12. [PMID: 29225084 DOI: 10.1016/j.jaci.2017.10.038] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2017] [Revised: 10/02/2017] [Accepted: 10/23/2017] [Indexed: 12/31/2022]
Abstract
BACKGROUND Eosinophilic inflammation is a major pathologic feature of chronic rhinosinusitis (CRS) and is frequently associated with severe refractory disease. Prostaglandin (PG) D2 levels are increased in patients with CRS, and PGD2 is an important contributing factor to eosinophilic inflammation. Autophagy has a pleiotropic effect on immune responses and disease pathogenesis. Recent studies suggest the potential involvement of autophagy in patients with CRS and the PG pathway. OBJECTIVE We sought to investigate whether altered function of autophagy is associated with eosinophilic inflammation and dysregulated production of PGD2 in patients with CRS. METHODS We used myeloid cell-specific deletion of autophagy-related gene 7 (Atg7), which is vital for autophagy, and investigated the effects of impaired autophagy on eosinophilic inflammation in a murine model of eosinophilic chronic rhinosinusitis (ECRS). The effect of autophagy on PGD2 production and gene expression profiles associated with allergy and the PG pathway were assessed. RESULTS We found that impaired autophagy in myeloid cells aggravated eosinophilia, epithelial hyperplasia, and mucosal thickening in mice with ECRS. This aggravation was associated with gene expression profiles that favor eosinophilic inflammation, TH2 response, mast cell infiltration, and PGD2 dysregulation. Supporting this, PGD2 production was also increased significantly by impaired autophagy. Among other myeloid cells, macrophages were associated with autophagy deficiency, leading to increased IL-1β levels. Macrophage depletion or blockade of IL-1 receptor led to alleviation of eosinophilic inflammation and sinonasal anatomic abnormalities associated with autophagy deficiency. CONCLUSION Our results suggest that impaired autophagy in myeloid cells, particularly macrophages, has a causal role in eosinophilic inflammation and ECRS pathogenesis.

Abstract
Bioactive lipids regulate most physiological processes, from digestion to blood flow and from hemostasis to labor. Lipid mediators are also involved in multiple pathologies including cancer, autoimmunity or asthma. The pathological roles of lipid mediators are based on their intricate involvement in the immune system, which comprises source and target cells of these mediators. Based on their biosynthetic origin, bioactive lipids can be grouped into different classes [e.g. sphingolipids, formed from sphingosine or eicosanoids, formed from arachidonic acid (AA)]. Owing to the complexity of different mediator classes and the prominent immunological roles of eicosanoids, this review will focus solely on the immune-regulation of eicosanoids. Eicosanoids do not only control key immune responses (e.g. chemotaxis, antigen presentation, phagocytosis), but they are also subject to reciprocal control by the immune system. Particularly, key immunoregulatory cytokines such as IL-4 and IFN-γ shape the cellular eicosanoid profile, thus providing efficient feedback regulation between cytokine and eicosanoid networks. For the purpose of this review, I will first provide a short overview of the most important immunological functions of eicosanoids with a focus on prostaglandins (PGs) and leukotrienes (LTs). Second, I will summarize the current knowledge on immunological factors that regulate eicosanoid production during infection and inflammation.

Endothelial Regulator of Calcineurin 1 Promotes Barrier Integrity and Modulates Histamine-Induced Barrier Dysfunction in Anaphylaxis. Front Immunol 2017; 8:1323.

Abstract
Anaphylaxis, the most serious and life-threatening allergic reaction, produces the release of inflammatory mediators by mast cells and basophils. Regulator of calcineurin 1 (Rcan1) is a negative regulator of mast-cell degranulation. The action of mediators leads to vasodilation and an increase in vascular permeability, causing great loss of intravascular volume in a short time. Nevertheless, the molecular basis remains unexplored on the vascular level. We investigated Rcan1 expression induced by histamine, platelet-activating factor (PAF), and epinephrine in primary human vein (HV)-/artery (HA)-derived endothelial cells (ECs) and human dermal microvascular ECs (HMVEC-D). Vascular permeability was analyzed in vitro in human ECs with forced Rcan1 expression using Transwell migration assays and in vivo using Rcan1 knockout mice. Histamine, but neither PAF nor epinephrine, induced Rcan1-4 mRNA and protein expression in primary HV-ECs, HA-ECs, and HMVEC-D through histamine receptor 1 (H1R). These effects were prevented by pharmacological inhibition of calcineurin with cyclosporine A. Moreover, intravenous histamine administration increased Rcan1 expression in lung tissues of mice undergoing experimental anaphylaxis. Functional in vitro assays showed that overexpression of Rcan1 promotes barrier integrity, suggesting a role played by this molecule in vascular permeability. Consistent with these findings, in vivo models of subcutaneous and intravenous histamine-mediated fluid extravasation showed increased response in skin, aorta, and lungs of Rcan1-deficient mice compared with wild-type animals. These findings reveal that endothelial Rcan1 is synthesized in response to histamine through a calcineurin-sensitive pathway and may reduce barrier breakdown, thus contributing to the strengthening of the endothelium and resistance to anaphylaxis. These new insights underscore its potential role as a regulator of sensitivity to anaphylaxis in humans.

Abstract
BACKGROUND IgE/Ag-stimulated mast cells release various pro-allergic inflammatory mediators, including histamine, eicosanoids, and pro-inflammatory cytokines. NecroX-5, a cell permeable necrosis inhibitor, showed cytoprotective effects in both in vitro and in vivo models. However, the anti-allergic effect of NecroX-5 has not yet been investigated. The aims of this study were to evaluate the anti-allergic activity of NecroX-5 in vivo and to investigate the underlying mechanism in vitro. METHODS The anti-allergic activity of NecroX-5 was evaluated in vitro using bone marrow-derived mast cells (BMMCs) and IgE receptor-bearing RBL-2H3 or KU812 cells and in vivo using a mouse model of passive anaphylaxis. The levels of histamine, eicosanoids (PGD2 and LTC4 ), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured using enzyme immunoassay kits. The mechanism underlying the action of NecroX-5 was investigated using immunoblotting, immunoprecipitation, and gene knockdown techniques. RESULTS NecroX-5 markedly inhibited mast cell degranulation and the synthesis of eicosanoids, TNF-α, and IL-6 by suppressing the activation of Syk, LAT, phospholipase Cγ1, MAP kinases, the Akt/NF-κB pathway, and intracellular Ca(2+) mobilization via the activation of phosphatase SHP-1. Oral administration of NecroX-5 effectively suppressed mast cell-dependent passive cutaneous and systemic anaphylactic reactions in a dose-dependent manner. CONCLUSIONS NecroX-5 might be a potential candidate for the development of a novel anti-allergic agent that suppresses IgE-dependent mast cells signaling.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE 15,16-Dihydrotanshinone I (DHT-I), isolated from the dried root of Salvia miltiorrhiza Bung, which is traditionally used to treat cardiovascular and inflammatory diseases agent in Chinese medicine. DHT-I has been reported to have a broad range of biological activities, including antibacterial activity, and has been used to treat circulatory disorders, hepatitis, inflammation, cancer, and neurodegenerative diseases. AIM OF THE STUDY The aim of this study was to evaluate the anti-allergic inflammatory effects of DHT-I on degranulation and on the generation of eicosanoids, such as, prostaglandin D2 (PGD2) and leukotriene C4 (LTC4), in IgE/Ag-stimulated bone marrow-derived mast cells (BMMCs). MATERIALS AND METHODS The anti-allergic inflammatory activity of DHT-I was evaluated using BMMCs. The effects of DHT-I on mast cell activation were investigated by following degranulation and eicosanoid generation using ELISA and immunoblotting and immunoprecipitation techniques. RESULTS DHT-I at a concentration of 20μM markedly inhibited degranulation and the generation of PGD2 and LTC4 in IgE/Ag-stimulated BMMCs (about 90% inhibitions, respectively). Analyses of FcεRI-mediated signaling pathways demonstrated that DHT-I inhibited the phosphorylations of spleen tyrosine kinase (Syk) and linker for activation of T cells (LAT), and inhibited downstream signaling process, including [Ca(2+)]i mobilization induced by the phosphorylation of phospholipase Cγ1 (PLCγ1), and the activations of mitogen-activated protein kinases (MAPKs) and the Akt-nuclear factor-κB (NF-κB) pathway. CONCLUSIONS DHT-1 inhibits the release of allergic inflammatory mediators from IgE/Ag-stimulated mast cells by suppressing a FcεRI-mediated Syk-dependent signal pathway. This result suggests DHT-I offers a novel developmental basis for drugs targeting allergic inflammatory diseases.

Abstract
Inflammation is the first response of animals to infection or tissue damage. Sparus aurata (Perciformes) was the first fish species shown to possess histamine-containing mast cells at mucosal tissues. We report a separation protocol for obtaining highly enriched (over 95% purity) preparations of fish mast cells in high numbers (5-20 million mast cells per fish). The peritoneal exudate of S. aurata is composed of lymphocytes, acidophilic granulocytes, macrophages and mast cells. We separated the lymphocyte fraction through discontinuous density gradient centrifugation. The remaining cells were cultivated overnight in RPMI-1640 culture medium containing 5% fetal calf serum, which allowed macrophages to adhere to the cell culture flasks. Finally, acidophilic granulocytes were separated from the mast cells though a Magnetic-Activated Cell Separation (MACS) protocol, using a monoclonal antibody against these cells. The purity of mast cells-enriched fractions was analyzed by flow cytometry and by transmission electron microscopy. The functionality of purified mast cells was confirmed by the detection of histamine release by ELISA after stimulation with compound 48/80 and the induction of the pro-inflammatory cytokines IL-1β and IL-8 following stimulation with bacterial DNA. This fish mast cells separation protocol is a stepping stone for further studies addressing the evolution of vertebrate inflammatory mechanisms.

Abstract
Curcumin is naturally occurring polyphenolic compound found in turmeric and has many pharmacological activities. The present study was undertaken to evaluate anti-allergic inflammatory activity of curcumin, and to investigate its inhibitory mechanisms in immunoglobulin E (IgE)/Ag-induced mouse bone marrow-derived mast cells (BMMCs) and in a mouse model of IgE/Ag-mediated passive systemic anaphylaxis (PSA). Curcumin inhibited cyclooxygenase-2 (COX-2) dependent prostaglandin D2 (PGD2) and 5-lipoxygenase (5-LO) dependent leukotriene C4 (LTC4) generation dose-dependently in BMMCs. To probe the mechanism involved, we assessed the effects of curcumin on the phosphorylation of Syk and its downstream signal molecules. Curcumin inhibited intracellular Ca2+ influx via phospholipase Cγ1 (PLCγ1) activation and the phosphorylation of mitogen-activated protein kinases (MAPKs) and the nuclear factor-κB (NF-κB) pathway. Furthermore, the oral administration of curcumin significantly attenuated IgE/Ag-induced PSA, as determined by serum LTC4, PGD2, and histamine levels. Taken together, this study shows that curcumin offers a basis for drug development for the treatment of allergic inflammatory diseases.

Lu Y, Son JK, Chang HW. Saucerneol F, a New Lignan Isolated from Saururus chinensis, Attenuates Degranulation via Phospholipase Cγ 1 Inhibition and Eicosanoid Generation by Suppressing MAP Kinases in Mast Cells. Biomol Ther (Seoul) 2013; 20:526-31. [PMID: 24009845 PMCID: PMC3762291 DOI: 10.4062/biomolther.2012.20.6.526] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2012] [Revised: 09/18/2012] [Accepted: 10/15/2012] [Indexed: 11/10/2022] Open
Abstract
During our on-going studies to identify bioactive compounds in medicinal herbs, we found that saucerneol F (SF), a naturally occurring sesquilignan isolated from Saururus chinensis (S. chinensis), showed in vitro anti-inflammatory activity. In this study, we examined the effects of SF on the generation of 5-lipoxygenase (5-LO) dependent leukotriene C4 (LTC4), cyclooxygenase-2 (COX-2) dependent prostaglandin D2 (PGD2), and on phospholipase Cγ1 (PLCγ1)-mediated degranulation in SCF-induced mouse bone marrow-derived mast cells (BMMCs). SF inhibited eicosanoid (PGD2 and LTC4) generation and degranulation dose-dependently. To identify the molecular mechanisms underlying the inhibition of eicosanoid generation and degranulation by SF, we examined the effects of SF on the phosphorylation of PLCγ1, intracellular Ca2+ influx, the translocation of cytosolic phospholipase A2 (cPLA2) and 5-LO, and on the phosphorylation of MAP kinases (MAPKs). SF was found to reduce intracellular Ca2+ influx by inhibiting PLCγ1 phosphorylation and suppressing the nuclear translocations of cPLA2 and 5-LO via the phosphorylations of MAPKs, including extracellular signal-regulated protein kinase-1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), and p38. Taken together, these results suggest that SF may be useful for regulating mast cell-mediated inflammatory responses by inhibiting degranulation and eicosanoid generation.

Abstract
The high-affinity receptor for immunoglobulin E (IgE) (FcεRI)-mediated activation of mast cells plays an important role in various allergic diseases. To assess the anti-allergic activity of natural vanadium-containing Jeju groundwater (JW), an in vivo passive cutaneous anaphylaxis (PCA) animal model and in vitro mouse bone marrow-derived mast cells (BMMCs) was used. JW inhibited cyclooxygenase-2 (COX-2)-dependent prostaglandin D(2) (PGD(2)) generation in a dose-dependent manner, with a concomitant reduction of COX-2 protein expression in IgE-induced BMMCs. In addition, JW inhibited 5-lipoxygenase (5-LOX)-dependent generation of leukotriene C(4) (LTC(4)) as well as degranulation in a dose-dependent manner. These results demonstrate that JW has dual COX-2/5-LOX inhibitory activity. In addition, vanadium pentoxide (V(2)O(5)), which is the major vanadium component of JW, also inhibited PGD(2) and LTC(4) generation as well as degranulation in IgE-induced BMMCs. Furthermore, oral administration of JW dose-dependently inhibited mast cell-dependent passive anaphylactic reaction in IgE-sensitized mice. Taken together, these results suggest that JW may be useful in regulating mast cell-mediated allergic response through the suppression of eicosanoid generation and degranulation in mast cells.

Abstract
The aim of the present study was to evaluate the inhibitory effect of glycoprotein isolated from Cudrania tricuspidata Bureau (CTB glycoprotein) on di(2-ethylhexyl) phthalate (DEHP)-induced allergic inflammatory response in mice. We evaluated the activity of β-hexosaminidase, expression of cyclooxygenase (COX)-2, p38 mitogen-activated protein kinase (MAPK), and activator protein (AP)-1, and production of immunoglobulin (Ig)E and interleukin (IL)-4 in DEHP-treated RBL-2H3 cells and ICR mice. Our results revealed that the CTB glycoprotein inhibited the activity of β-hexosaminidase and production of IgE and IL-4 in serum from DEHP-treated mice. We also found that the CTB glycoprotein reduced arachidonic acid release, COX-2 expression, and AP-1 transcriptional activation through p38 MAPK phosphorylation in DEHP-treated RBL-2H3 cells. The activation of AP-1 was completely blocked by treatment with p38 MAPK inhibitor (SKF86002). The results from these experiments indicate that CTB glycoprotein effectively protects against the allergic inflammation response, mainly through downregulation of MAPK/AP-1 in the mast cell degranulation stage. In conclusion, we suggest that the CTB glycoprotein may be one component of health supplements for the prevention of allergic inflammation.

Abstract
In this study, we examined the effects of citreorosein (CIT), an anthraquinone component of Polygoni cuspidati radix (P. cuspidati, Polygonaceae), on cyclooxygenase (COX)-2 dependent prostaglandin (PG)D2 generation in mast cells, central effector cells of allergy and other inflammatory diseases. CIT strongly inhibited COX-2-dependent PGD2 generation in a concentration-dependent manner in mouse bone marrow-derived mast cells (BMMCs) stimulated with stem cell factor (SCF)/IL-10/LPS. In an effort to identify the mechanisms underlying the inhibition of COX-2-dependent PGD2 generation by CIT, we examined the effects of this compound on MAP kinases, Akt and NF-κB signaling pathways, which are essential for COX-2 induction. CIT inhibited nuclear translocation of the nuclear factor (NF)-κB p65 subunit and its cognate DNA-binding activity, which correlated with its inhibitory effects on the phosphorylation of Akt and IKK and subsequent phosphorylation and degradation of IκB. Furthermore, CIT significantly attenuated the DNA binding of activator protein (AP)-1 that regulates COX-2 expression through the reduction of the phosphorylation of c-Jun. Moreover, inhibition of PGD2 generation by CIT was accompanied by a decrease in phosphorylation of cytosolic phospholipase A2α. Taken together, the present study suggests that CIT represents a potential therapeutic approach for the treatment of inflammatory diseases.

Abstract
The high-affinity receptor for IgE (FcɛRI)-mediated activation of mast cells plays an important role in allergic diseases such as asthma, allergic rhinitis and atopic dermatitis. Emodin, a naturally occurring anthraquinone derivative in oriental herbal medicines, has several beneficial pharmacologic effects, such as anti-cancer and anti-diabetic activities. However, the anti-allergic effect of emodin has not yet been investigated. To assess the anti-allergic activity of emodin, in vivo passive anaphylaxis animal model and in vitro mouse bone marrow-derived mast cells were used to investigate the mechanism of its action on mast cells. Our results showed that emodin inhibited degranulation, generation of eicosanoids (prostaglandin D(2) and leukotriene C(4)), and secretion of cytokines (TNF-α and IL-6) in a dose-dependent manner in IgE/Ag-stimulated mast cells. Biochemical analysis of the FcɛRI-mediated signaling pathways demonstrated that emodin inhibited the phosphorylation of Syk and multiple downstream signaling processes including mobilization of intracellular Ca(2+) and activation of the mitogen-activated protein kinase, phosphatidylinositol 3-kinase, and NF-κB pathways. When administered orally, emodin attenuated the mast cell-dependent passive anaphylactic reaction in IgE-sensitized mice. Thus, emodin inhibits mast cell activation and thereby the anaphylactic reaction through suppression of the receptor-proximal Syk-dependent signaling pathways. Therefore, emodin might provide a basis for development of a novel anti-allergic drug.

Abstract
This study investigated the in vitro effect of Lactobacillus strains, a major group of probiotic lactic acid bacteria, on immunoglobulin E (IgE)- and antigen-induced mast cell degranulation and subsequent gene expression. Bone marrow-derived mast cells (BMMCs) from DBA/2 mice were cultured with heat-killed Lactobacillus strains for 24 h. Some strains significantly inhibited IgE- and antigen-induced β-hexosaminidase release from BMMCs. Furthermore, Lactobacillus reuteri NBRC 15892, which exhibited the strongest inhibitory activity, significantly reduced the elevated interleukin (IL)-4, IL-13, tumor necrosis factor-α, and cyclooxygenase-2 expression levels that was induced by 1-2 h of stimulation with IgE and antigens. The suppressive effect of NBRC 15892 strain on BMMC degranulation was significantly reduced in the presence of a toll-like receptor (TLR)2-neutralizing antibody. In addition, downregulation of cell surface FcεRIα expression was observed after 6 h of NBRC 15892 treatment. These results suggest that some Lactobacillus strains inhibited IgE-mediated mast cell degranulation and subsequent late-phase reactions involving mast cells via a TLR2-dependent mechanism with FcεRIα downregulation.

Abstract
Psidium guajava (P. guajava) is an important food crop and medicinal plant with antioxidant, anti-inflammatory, and anti-allergic activities, supporting its traditional uses. However, its precise effects remain unknown. We investigated the effects of P. guajava ethyl acetate extract (PGEA) on IgE-mediated allergic responses in rat mast RBL-2H3 cells. PGEA reduced antigen (DNP-BSA)-induced release of β-hexosaminidase and histamine in IgE-sensitized RBL-2H3 cells. In addition, it inhibited antigen-induced IL-4 and TNF-α mRNA expression and protein production in IgE-sensitized RBL-2H3 cells. PGEA also suppressed antigen-induced COX-2 mRNA and protein expression in these cells, as well as antigen-induced activation of NFAT and reactive oxygen species. Moreover, it inhibited antigen-induced activation of NF-κB and degradation of IκB-α. To identify the mechanisms underpinning the inhibition of degranulation and cytokine production by PGEA, we examined the activation of intracellular FcεRI signaling molecules. PGEA suppressed antigen-induced phosphorylation of Syk, LAT, Gab2, and PLCγ2 but not Lyn, and inhibited antigen-induced phosphorylation of downstream signaling intermediates including MAP kinases and Akt. Collectively, the anti-allergic effects of PGEA in vitro suggest its possible therapeutic application to inflammatory allergic diseases, in which its inhibition of inflammatory cytokine production and FcεRI-dependent signaling events in mast cells may be hugely beneficial.

Abstract
Nitric oxide (NO) is an important signaling molecule that regulates MC function. However, the involvement of NO in an important lipid mediator, prostaglandin (PG) D(2) production by MC, is unclear. The role of NO in cyclooxygenase (COX)-2 expression and PGD(2) generation as well as IL-6 production in mouse bone marrow-derived MC (BMMC) was investigated using NO donors. Exogenous NO augmented COX-2 protein expression and increased COX-2-dependent PGD(2) generation in response to SCF, IL-10, and IL-1beta, or antigen activation in combination with IL-10 and IL-1beta after sensitization with IgE. The increased expression of COX-2 by NO donors was inhibited by hemoglobin. Moreover it was not affected by soluble guanylyl cyclase inhibitor, but reduced by the p38 MAPK inhibitor, SB202190. Downstream of p38 MAPK, NO donors augmented not only COX-2 mRNA transcription but also its stability. Exogenous NO also augmented IL-6 production by SCF, IL-10, and IL-1beta. These results show that exogenous NO can increase COX-2-dependent PGD(2) and IL-6 production by MC in inflammatory environments through the p38 MAPK pathway. Therefore, our novel observations suggest that the effect of NO on MC is not limited to the suppression of their activation as has been the emphasis previously, but can also augment certain MC responses.

Abstract
Mast cell stimulation leads to an early response with histamine release and prostaglandin (PGD(2)) production but attempts to link these two events have been contradictory. In IgE-mediated mast cell activation, a late-phase PGD(2)-production is caused by increased cyclooxygenase-2 (COX-2) expression whereas a COX-2 involvement in the early response is uncertain. The present study compares the influence of four COX-inhibitors (NSAIDs) on the histamine release of mast cells from naïve and actively sensitized rats. NSAIDs of different COX-1 vs. COX-2 selectivity were used, i.e. acetylsalicylic acid (ASA), piroxicam, meloxicam, and NS-398, a selective COX-2-inhibitor. All could inhibit antigen-induced histamine release, with 64%, 34%, 27% and 85% inhibition by ASA (5 mM), piroxicam (100 microM), meloxicam (100 microM) and NS-398 (100 microM), respectively. Similar inhibition was found with compound 48/80 without calcium added to the medium whereas compound 48/80 with calcium was affected less by ASA and NS-398 and unaffected by the oxicams. Only small differences between the two kinds of mast cells were found, except with NS-398 which was a significantly more effective inhibitor of naïve than sensitized cells when exposed to compound 48/80 with calcium present. The results do not show any consistent relationship between the influence of the NSAIDs and their COX-2-selectivity. The high NSAID-concentrations required for inhibition cast doubt about an involvement of COX-inhibition and indicate additional or other targets. The results seem to exclude toxic effects on mast cell energy production but are consistent with an interference with the calcium disposition.

Abstract
Several studies have demonstrated that nonsteroidal anti-inflammatory drugs, such as acetylsalicylic acid (ASA), can have inhibitory or enhancing effects on inflammatory cell function. These effects seem independent of cyclooxygenase activity and prostaglandin synthesis inhibition. Here, we examined the effect of ASA on bone marrow-derived mast cells in more detail. ASA blocked the expression of cyclooxygenase-2, the production of tumor necrosis factor-alpha and interleukin-6, and the release of granule mediators from mast cells in a concentration-dependent fashion. Concomitantly, ASA inhibited nuclear factor (NF)-kappaB activity, as well as the phosphorylation and breakdown of the inhibitory protein IkappaB-alpha. We thus propose that the anti-inflammatory effects of ASA in mast cells are due to suppression of IkappaB kinase activity, thereby inhibiting subsequent phosphorylation and degradation of IkappaB-alpha, activation of NF-kappaB, and transcription of proinflammatory cytokines. The inhibition of BMMC degranulation was independent of NF-kappaB activation, however. Interestingly, the expression of cyclooxygenase-2 was not inhibited at 1mM ASA, but was even enhanced significantly. The latter might contribute to the adverse effects of ASA in ASA-sensitive asthmatics.

Abstract
This study investigated the capacity of conjugated linoleic acids (CLA) to reduce ex vivo antigen-induced release of eicosanoids in a type I hypersensitivity model. Guinea pigs were fed a diet containing 0.25% safflower oil (control) or 0.25% CLA [43% trans (t)10, cis (c)12; 41% c9, t11/t9, c11 18:2] for 2 wk before and during sensitization to ovalbumin (OVA). Lungs, tracheas, and bladders were incubated in physiological saline solution (PSS) for 1 h (basal mediator release) and challenged with OVA (0.01 g/l PSS) for 1 h (mediator release in response to antigen). Eicosanoids were quantified by HPLC/tandem mass spectrometry or enzyme immunoassay. CLA feeding resulted in no change in basal release but decreased eicosanoid release from sensitized tissues in response to antigen challenge in the following manner: thromboxane B(2), 6-keto-prostaglandin (PG)F(1alpha), PGF(2alpha), PGD(2), PGE(2) by 57-75% in lung, 45-65% in trachea, and 38-60% in bladder; and leukotriene C(4)/D(4)/E(4) by 87, 90, and 50% in lung, trachea, and bladder, respectively. These data indicate that feeding CLA reduces lipid-derived inflammatory mediators produced by this type I hypersensitivity model.

Abstract
We have investigated possible factors that underlie changes in the production of eicosanoids after prolonged exposure of mast cells to Ag. Ag stimulation of cultured RBL-2H3 mast cells resulted in increased expression of cyclooxygenase (COX-2) protein and message. Other eicosanoid-related enzymes, namely COX-1, 5-lipoxygenase, and cytosolic phospholipase A(2) were not induced. Activation of extracellular signal-regulated kinase, c-Jun N-terminal kinase, and p38 mitogen-activated protein (MAP) kinase preceded the induction of COX-2, whereas phosphatidylinositol 3' kinase and its substrate, Akt, were constitutively activated in RBL-2H3 cells. Studies with pharmacologic inhibitors indicated that of these kinases, only p38 MAP kinase regulated expression of COX-2. The induction of COX-2 was blocked by the p38 MAP kinase inhibitor SB202190, even when added 12-16 h after stimulation with Ag when p38 MAP kinase activity had returned to near basal, but still minimally elevated, levels. Interestingly, expression of COX-2 as well as cytosolic phospholipase A(2) and 5-lipoxygenase were markedly reduced by SB202190 in unstimulated cells. Collectively, the results imply that p38 MAP kinase regulates expression of eicosanoid-related enzymes, passively or actively, at very low levels of activity in RBL-2H3 cells. Also, comparison with published data suggest that different MAP kinases regulate induction of COX-2 in inflammatory cells of different and even similar phenotype and suggest caution in extrapolating results from one type of cell to another.

Abstract
1. Methyl arachidonyl fluorophosphonate (MAFP), an inhibitor of phospholipase A2 (PLA2), has been widely used to assess the roles of PLA2 in various cell functions. Here, we report on a novel action of this compound at concentrations similar to those used for PLA2 inhibition. 2. The murine macrophage J774 released a large amount of prostaglandin E2 (PGE2) by MAFP (1-30 microM), which was abolished by indomethacin and NS-398 but not by valeryl salicylate, and results from increased cyclo-oxygenase-2 (COX-2) protein levels and gene expression. 3. This PGE2 release was blocked by inhibitors of tyrosine kinase (genistein), protein kinase C (PKC) (Ro 31-8220, Go 6976 or LY 379196), mitogen-activated protein kinase kinase (MEK) (PD 098059) or p38 mitogen-activated protein kinase (MAPK) (SB 203580). 4. Consistent with these results, MAFP caused membrane translocation of PKCbetaI and betaII isoforms and activated extracellular signal-regulated kinase (ERK) and p38 MAPK. 5. In accordance with these effects of MAFP, PKC activator phorbol 12-myristate 13-acetate (PMA) increased PGE2 release and caused activation of PKCbeta, ERKs and p38 MAPK. 6. This is the first report that the PLA2 inhibitor, MAFP, can induce COX-2 gene expression and PGE2 synthesis via the PKC-, ERK- and p38 MAPK-dependent pathways. Thus, the use of MAFP as a PLA2 inhibitor should be treated with caution.

Abstract
Abstract
Mast cells exhibit a biphasic (immediate and delayed) eicosanoid-biosynthetic response after stimulation with particular cytokines or FcεRI (high affinity receptor for IgE) cross-linking. Treatment of rat serosal connective tissue mast cells (CTMC) with nerve growth factor (NGF) induced only the delayed phase of PGD2 generation that depended on inducible cyclooxygenase-2 (COX-2), but not constitutive COX-1, even though the subcellular distributions of these isoforms were similar. Experiments using several phospholipase A2 (PLA2) isozyme-specific probes and inhibitors suggested that both constitutive cytosolic PLA2 and inducible type IIA secretory PLA2 (sPLA2) are involved in NGF-initiated, COX-2-dependent, delayed PGD2 generation in rat CTMC. A type IIA sPLA2 inhibitor, but neither cytosolic PLA2 nor COX inhibitors, reduced, while adding exogenous type IIA sPLA2 augmented, NGF-induced COX-2 expression and its attendant PGD2 generation, indicating that the sPLA2-mediated increase in delayed PGD2 generation was attributable mainly to enhanced COX-2 expression. Type IIA sPLA2 and its close relative type V sPLA2 associated with fibroblastic cell surfaces increased NGF-induced COX-2 expression more efficiently than the soluble enzymes, revealing a particular juxtacrine sPLA2 presentation route. Surprisingly, catalytically inactive type IIA sPLA2 mutants, which were incapable of promoting arachidonic acid release from cytokine-primed cells, retained the ability to enhance COX-2 expression in CTMC, indicating that the COX-2-inducing activities of sPLA2 are independent of their catalytic functions.

Abstract
Emerging evidence has suggested the pivotal role of mast cells in a host defense against bacterial infection. In this paper, we report that bacterial lipopolysaccharide (LPS) is a potent enhancer of the cytokine- and IgE-dependent delayed responses of IL-3-dependent mouse bone marrow-derived cultured mast cells (BMMC). LPS, although showing minimal effects, significantly augmented the c-kit ligand (KL)- or IgE-dependent expression of cyclooxygenase (COX)-2 and the attendant delayed PGD2 generation, with IL-10 and IL-4 acting as potentiating and inhibitory cytokines, respectively. The COX-2-inducing activity of LPS was mimicked by exogenous IL-1 beta. Assessment of endogenous cytokine induction revealed that IL-1 beta expression was stimulated by either LPS or exogenous IL-1 beta. IL-6 expression occurred in parallel with COX-2 expression. IL-10 expression, which lagged behind COX-2 expression, depended on exogenous IL-10, but not on LPS and IL-1 beta. Thus, LPS and IL-1 beta exhibited similar biological activities in terms of COX-2 and endogenous cytokine expression. However, adding an antibody against the type I IL-1 receptor to BMMC, which abrogated the effects of IL-1 beta, failed to neutralize the effects of LPS. These results suggest that LPS activates BMMC through the signal transduction pathway shared with exogenous IL-1 beta, rather than exerting its action indirectly via the production of endogenous IL-1 beta.

Abstract
We previously reported that BALB/cJ mouse-derived bone marrow-derived mast cells (BMMC) exhibited two sequential phases of prostaglandin D2 (PGD2) generation in response to Fc(epsilon) receptor I (Fc(epsilon)RI) crosslinking and cytokine stimulation, the late phase of which was suppressed by an antibody raised against type IIA secretory phospholipase A2 (sPLA2). Here we report that BMMC derived from C57BL/6J mice, which are genetically deficient in type IIA sPLA2, display both immediate and delayed PGD2 generation normally. Lysates of C57BL/6J-derived BMMC contained a Ca2+-dependent PLA2 that was absorbed to a column conjugated with anti-type IIA sPLA2 antibody and had a similar molecular mass of 14 kDa, as assessed by immunoblotting. Therefore we speculate that a sPLA2 similar to, but distinct from, type IIA sPLA2 would compensate for type IIA sPLA2 deficiency in C57BL/6J-derived BMMC. We found that the two type IIA-related sPLA2 family members, type V and type IIC sPLA2s, were expressed in BMMC as well as in rat mastocytoma RBL-2H3 cells.

Abstract
IgE-dependent and -independent activation of mouse bone marrow-derived mast cells (BMMC) elicited rapid and transient production of platelet-activating factor (PAF), which reached a maximal level by 2-5 min and was then degraded rapidly, returning to base-line levels by 10-20 min. Inactivation of PAF was preceded by the release of PAF acetylhydrolase (PAF-AH) activity, which reached a plateau by 3-5 min and paralleled the release of beta-hexosaminidase, a marker of mast cell exocytosis. Immunochemical and molecular biological studies revealed that the PAF-AH released from activated mast cells was identical to the plasma-type isoform. In support of the autocrine action of exocytosed PAF-AH, adding exogenous recombinant plasma-type PAF-AH markedly reduced PAF accumulation in activated BMMC. Furthermore, culture of BMMC with a combination of c-kit ligand, interleukin-1beta and interleukin-10 for > 24 h led to an increase in plasma-type PAF-AH expression, accompanied by a reduction in stimulus-initiated PAF production. Collectively, these results suggest that plasma-type PAF-AH released from activated mast cells sequesters proinflammatory PAF produced by these cells, thereby revealing an intriguing anti-inflammatory aspect of mast cells.
