Abstract
Background The IgE-mediated activation of mast cells and basophils results in the secretion of many substances, including the release of FceRI-alpha subunit. This released alpha subunit can bind IgE and it may act as a down-regulator of subsequent IgE-dependent reactions. However, previous studies do not observe loss of the mass of FceRI-alpha associated with the cells, at least not for human basophils. This study was designed to understand the basis for the discordant observations. Methods Purified human basophils were stimulated with multiple activating secretagogues and supernatants were examined for histamine and released FceRI-alpha. In addition, cell surface IgE densities (occupied and unoccupied) were measured by flow cytometry and total cellular content of mature and immature FceRI-alpha determined with Western blots. Results Released FceRI-alpha, on average, represented 7% of the total surface FceRI before the reaction. The molecular weight of the soluble FceRI-alpha was approximately 54 kD, larger than immature subunit and somewhat smaller than surface subunit. In addition, 1) release ceased long before internalized FceRI-alpha was processed, 2) release was insensitive to Bafilomycin A, 3) release was independent of the starting density of FceRI and 4) release occurred more effectively with non-IgE-dependent stimuli, FMLP or C5a. Conclusions There appears to be relatively constant amount of nearly mature FceRI-alpha that is susceptible to secretion events induced by any form of stimulation. The amount, on average, represents about 7% of the mature form of FceRI-alpha.

Abstract
Calcitonin gene-related peptide (CGRP), nitric oxide (NO) and histamine are implicated in primary headaches but their role in vascular and nociceptive events in the dura mater is not well described. In an in vitro preparation of the hemisected rat skull, CGRP and histamine release from the cranial dura was measured using enzyme-linked immunoassays. While the NO donator NONOate (10-4 M) was without effect, CGRP (10-5 M) induced considerable histamine release from the rat cranial dura, which was blocked by the CGRP receptor antagonist CGRP8-37 (10-5 M). Conversely, histamine (10-4 M) did not stimulate CGRP release. In vitro recordings from single rat meningeal afferents showed that only one of 12 mechanically identified units but several mechanically insensitive units responded to histamine (up to 10-5 M). Increases in meningeal blood flow after histamine application (10-4 M) to the rat cranial dura remained unchanged during CGRP receptor blockade with CGRP8-37, inhibition of NO synthesis with L-NAME (20 mg/kg i.v.) and H3 receptor blockade with thioperamide (10-4 M). We conclude that histamine produces direct vasodilatation and activates a subset of largely non-mechanically sensitive, non-CGRP containing afferents in the rat meninges. Histamine is released from meningeal mast cells which are stimulated by CGRP. Similar mechanisms may be involved in the pathogenesis of headaches.

Abstract
Human basophils have been implicated in the pathogenesis of chronic spontaneous urticaria (CSU), and substance P (SP) is a possible candidate as histamine-releasing factor in some patients with CSU. However, little is known of relationship between basophils and SP in CSU. In the present study, we investigated expression of SP and NK1R on basophils from patients with CSU, and influence of SP on basophil functions by using flow cytometry analysis, basophil challenge, and mouse sensitization model techniques. The results showed that plasma SP level and basophil numbers in CSU patients were higher than that in HC subject. The percentages of SP+ and NK1R+ basophils were markedly elevated in CSU blood in comparison with HC blood. Once added, SP induced up to 41.2 % net histamine release from basophils of CSU patients, which was comparable with that provoked by anti-IgE, and fMLP. It appeared that SP induced dramatic increase in blood basophil numbers of mice following peritoneal injection. Ovalbumin (OVA)-sensitized mice had much more SP+ and NK1R+ basophils in blood than non-sensitized mice. In conclusion, the elevated plasma concentration of SP, upregulated expression of SP and NK1R on basophils, and the ability of SP in induction of basophil degranulation and accumulation indicate strongly that SP is most likely a potent proinflammatory mediator, which contributes greatly to the pathogenesis of CSU through basophils. Inhibitors of SP and blockers of NK1R are likely useful agents for treatment of CSU.

Abstract
Mast cell activation and degranulation can result in the release of various chemical mediators, such as histamine and cytokines, which significantly affect sleep. Mast cells also exist in the central nervous system (CNS). Since up to 50% of histamine contents in the brain are from brain mast cells, mediators from brain mast cells may significantly influence sleep and other behaviors. In this study, we examined potential involvement of brain mast cells in sleep/wake regulations, focusing especially on the histaminergic system, using mast cell deficient (W/Wv) mice. No significant difference was found in the basal amount of sleep/wake between W/Wv mice and their wild-type littermates (WT), although W/Wv mice showed increased EEG delta power and attenuated rebound response after sleep deprivation. Intracerebroventricular injection of compound 48/80, a histamine releaser from mast cells, significantly increased histamine levels in the ventricular region and enhanced wakefulness in WT mice, while it had no effect in W/Wv mice. Injection of H1 antagonists (triprolidine and mepyramine) significantly increased the amounts of slow-wave sleep in WT mice, but not in W/Wv mice. Most strikingly, the food-seeking behavior observed in WT mice during food deprivation was completely abolished in W/Wv mice. W/Wv mice also exhibited higher anxiety and depression levels compared to WT mice. Our findings suggest that histamine released from brain mast cells is wake-promoting, and emphasizes the physiological and pharmacological importance of brain mast cells in the regulation of sleep and fundamental neurobehavior.

Abstract
It has been reported that chymase activity was increased in allergic conjunctivitis patients and this activity was correlated with the severity of the disease. However, the precise roles of chymase in allergic conjunctivitis are unclear, and whether chymase inhibitors are effective for allergic conjunctivitis has not been reported even in experimental animal models. In this study, the roles of chymase in the pathogenesis were evaluated using a selective chymase inhibitor, ONO-WH-236, in a guinea pig model of allergic conjunctivitis induced by cedar pollen. Sensitized guinea pigs were challenged by the pollen, followed by assessing redness and edema in the conjuntiva, and counting the frequency of eye scratching as an itch-associated response. Treatment with the ONO-WH-236 (40 and 80 mg/kg, p.o.) dose-dependently inhibited the induction of redness, edema and scratching behavior. An anti-histaminic drug, ketotifen (3 mg/kg, p.o.), also significantly inhibited conjunctivitis symptoms. Chymase activity was increased in ophthalmic lavage fluid immediately after the pollen challenge. The increase in chymase activity was inhibited by in vivo treatment with ONO-WH-236. Interestingly, increased histamine in the ophthalmic lavage fluid immediately after the challenge was also inhibited by the chymase inhibitor. Administration of human recombinant chymase by eye dropping (0.09 and 0.9 μg/eye) dose-dependently induced scratching behavior, which was inhibited by not only ONO-WH-236 but also ketotifen; however, chymase administration induced only weak redness in the conjunctiva, which was resistant to treatment with anti-histaminic drugs. In conclusion, it was suggested that chymase was released from mast cells after antigen challenge, followed by the induction of conjunctivitis symptoms through histamine release from mast cells. Thus, chymase could be a potential target for pharmacotherapy for allergic conjunctivitis.

Abstract
Mast cells can secrete histamine in response to extrinsic stimuli. Histamine plays a role in the development of brain edema and can induce histamine receptor H3 (HRH3) expression in the brain to provide protective feedback effects against histamine neurotoxicity. We investigated time-dependent changes in dural mast cell numbers and HRH3 expression in the brain for one to 14 days after traumatic brain injury in a controlled cortical impact model in the rat. The number of tryptase-immunoreactive dural mast cells at the site of impact was significantly decreased one and four days after the injury. Furthermore, immunoreactivity and messenger RNA (mRNA) expression of HRH3 at the underlying cortical contusion site were significantly increased one and four days after the injury. These data suggest that histamine released from degranulated unstainable mast cells induces a transient increase in presynaptic autoinhibitory HRH3 immunoreactivity and mRNA expression as a mechanism to counteract histamine neurotoxicity.

Abstract
Chronic itch accompanying many dermatological, neurological, and systemic diseases is unresponsive to antihistamines. Our knowledge of endogenous chemicals that evoke histamine-independent itch and their molecular targets is very limited. Recently it was demonstrated in behavioral and cellular experiments that bovine adrenal medulla 8-22 peptide (BAM8-22), a proteolytically cleaved product of proenkephalin A, is a potent activator of Mas-related G-protein-coupled receptors (Mrgprs), MrgprC11 and hMrgprX1, and induces scratching in mice in an Mrgpr-dependent manner. To study the sensory qualities that BAM8-22 evokes in humans, we tested the volar forearm of 15 healthy volunteers with heat-inactivated cowhage spicules previously soaked in the peptide. BAM8-22 produced itch in each subject, usually accompanied by sensations of pricking/stinging and burning. The sensations were occasionally accompanied by one or more mechanically evoked dysesthesias, namely alloknesis, hyperknesis, and/or hyperalgesia, but no wheal or neurogenic flare in the skin surrounding the application site. The inactive truncated peptide BAM8-18 produced weak or no sensations. Pretreatment of the tested skin with an antihistamine cream (doxepin) inhibited histamine-induced sensations, dysesthesias, and skin reactions but not the sensations and dysesthesias evoked by BAM8-22. We show that BAM8-22 produces itch and nociceptive sensations in humans in a histamine-independent manner. Thus, BAM8-22 may be an endogenous itch mediator that activates, in humans, MrgprX1, a novel target for potential anti-itch treatments.

Abstract
Agave intermixta Trel. (Maguey) and Cissus sicyoides L. (Bejuco caro) are Caribbean plant species from the Dominican Republic used locally in traditional popular medicine that have shown an anti-inflammatory effect in experimental animal models. A phytochemical analysis on these species allowed us the isolation and identification of the steroidal sapogenins hecogenin and diosgenin from Maguey and the hydroxystilbene resveratrol from Bejuco caro. The effects of these plant extracts and their isolated constituents on compound-48/80-induced histamine release from peritoneal mast cells were investigated. Significant inhibition was produced by 0.5 mg mL−1 of a methanolic extract of Bejuco (41.1%) and by its constituent resveratrol (82.4%) at a dose of 250 μM. However, none of the steroidal sapogenins from A. intermixta showed a significant inhibitory effect on histamine release from mast cells. From these results, it can be deduced that the in-vitro anti-allergic activity towards the release of histamine from mast cells shown by the methanolic extract of C. sicyoides may be mediated by its constituent resveratrol and might contribute to the anti-inflammatory activity shown by this species.

Abstract
Chemokines are cytokines with chemotactic properties on inflammatory cells and other cell types. RANTES, MCP-1 and related molecules, constitute the C-C class of chemokine supergene family and a group of cytokines produced by hematopoietic cells, while IL-8 constitute the C-X-C class. The roles of most of these chemokines are not well known, although members of the chemokine family are inflammatory agents. The C-C chemokine plays a role in regulating Th-cell cytokine production and leukocyte trafficking. In this study we clearly show that RANTES and MCP-1 are mediators of acute inflammatory responses. Our report describes additional biological activities for RANTES, MCP-1, and IL-8, suggesting that these chemokines play a fundamental role in histamine and serotonin generation and cell function in mast cells.

Abstract
Allergic blood examination such as radioallergosorbent test (RAST) is an important and sensitive method for detecting the allergen against allergic diseases including bronchial asthma, allergic rhinitis, atopic dermatitis, and food allergy. In this review, blood examination such as RAST and histamine release test (HRT) will be discussed. In 1967, Wide et al developed allergen detecting system such as RAST that measures the allergen specific IgE antibody. Now, several systems including capsulated hydrophilic carrier polymer (CAP)-RAST or multiple antigen simultaneous test (MAST) by using the fluoroenzyme immunoassay (FEIA) or other methods by using the ELISA are available. Another method for blood test is HRT that measures histamine release from the peripheral blood basophils after antigen addition in vitro. In general, HRT is thought to be more sensitive than RAST but available for only ten allergens. Also, 10-20% of patients are non-responder for this test.

Abstract
The human mast cell line (HMC-1(560, 816)) was used to study the effect of the tyrosine kinase inhibitor STI571 (Glivec) on exocytosis, intracellular Ca(2+) and pH changes, because STI571 inhibits the proliferation of HMC-1(560) and induces its apoptosis. This drug does not have these effects on HMC-1(560, 816). Exocytosis in HMC-1(560, 816) cells can be stimulated by alkalinisation with NH(4)Cl as well as with ionomycin. Surprisingly 24-h pre-incubation with STI571 decreases spontaneous histamine release of HMC-1(560, 816) cells, but increases the histamine response after alkalinisation and not after ionomycin-stimulation. After addition of NH(4)Cl, pH(i) has a higher increase in STI571 pre-incubated cells, without changing intracellular Ca(2+) concentration. Activation of PKC in combination with tyrosine kinase inhibition increases also histamine release in HMC-1(560, 816) cells. Strangely, STI571 pre-incubated cells with PKC inhibited by rottlerin show the same effects. In these cells, cytosolic pH increases more than in control cells. This is the first report of STI571 effect in HMC-1(560, 816) cells. It seems that different pathways modulate signals for proliferation and exocytosis. STI571 does not only inhibit KIT TyrK, but may also influence cytosolic pH after alkalinisation in both cell lines, HMC-1(560) and HMC-1(560, 816), and this ends in induced histamine release. This work is important since HMC-1(560, 816) cells are reported in 80% of aggressive systemic mastocytosis cases and the understanding of some signalling pathways involved in mast cell response could facilitate drug targeting.

Abstract
Different types of dental materials (DM) were studied for their capacity to release histamine in vitro from basophils of whole blood of allergic patients and healthy donors using automated and computerized glass fiber-based leukocyte histamine release test (LHRT). It was shown that some types of DM possessed ability to release histamine from basophils and some didn't. There were no differences in histamine releaseability from basophils obtained from allergic patients and healthy donors. LHRT gives opportunity to recognize of DM possessing high or low histamine releaseability as well as to detect individual sensitivity to different DM. Thus, LHRT can be used for preliminary assessment of DM for their biocompatibility and also for individual selection of suitable DM for particular patient to avoid unwanted side effects.

Abstract
In the present study, it was investigated whether the degranulation of mast cells and histamine release were involved in rat pain-related behaviors and edema induced by the venom of scorpion Buthus martensi Karch (BmK) or not. It was found that the obvious degranulation of mast cells could be triggered in rat hindpaw skin by BmK venom. The chronic degranulation of mast cells using compound 48/80 relieved the spontaneous nociceptive responses, the primary thermal and bilateral mechanical hyperalgesia and the rat paw edema, as well as partially reduced c-Fos expression in superficial layers (laminae I-II) of bilateral spinal cord induced by BmK venom. In addition, individual peripheral co-administration of either 100 nmol chlorpheniramine or 100 nmol pyrilamine (histamine H(1) receptor antagonist) or 500 nmol cimetidine (histamine H(2) receptor antagonist) and BmK venom suppressed the spontaneous nociceptive responses, partially the primary thermal and bilateral mechanical hyperalgesia and rat paw edema induced by BmK venom. Thus, these results suggest that the peripheral cellular incidents of mast cells degranulation and histamine release are involved in BmK venom-induced pain-related behaviors and inflammation.

Abstract
IL-33 is a recently identified member of the IL-1 family of molecules, which also includes IL-1 and IL-18. IL-33 binds to the receptor, T1/ST2/IL-1R4, and can promote cytokine secretion by Th2 cells and NF-kappaB phosphorylation in mouse mast cells. However, the effects of these molecules, especially IL-33, in human mast cells are poorly understood. Expression of the receptors for IL-1 family molecules, specifically, IL-1R1, IL-18R and T1/ST2, was detectable intracellularly in human umbilical cord blood-derived mast cells (HUCBMCs) by flow cytometry, but was scarcely detectable on the cells' surface. However, IL-1beta, IL-18 or IL-33 induced phosphorylation of Erk, p38 and JNK in naïve HUCBMCs, and IL-33 or IL-1beta, but not IL-18, enhanced the survival of naive HUCBMCs and promoted their adhesion to fibronectin. IL-33 or IL-1beta also induced IL-8 and IL-13 production in naïve HUCBMCs, and enhanced production of these cytokines in IgE/anti-IgE-stimulated HUCBMCs, without enhancing secretion of either PGD(2) or histamine. Moreover, IL-33-mediated IL-8 production by HUCBMCs was markedly reduced by the p38 MAPK inhibitor, SB203580. In contrast to findings with mouse mast cells, IL-18 neither induced nor enhanced secretion of the mediators PGD(2) or histamine by HUCBMCs. Our findings identify previously unknown functions of IL-33 in human mast cells. One of these is that IL-33, like IL-1beta, can induce cytokine production in human mast cells even in the absence of stimuli of FcepsilonRI aggregation. Our findings thus support the hypothesis that IL-33 may enhance mast cell function in allergic disorders and other settings, either in the presence or absence of co-stimulation of mast cells via IgE/antigen-FcepsilonRI signals.

Abstract
The number of mast cells (MC) that can be obtained from tissue is limited, making it difficult to study the role of MC. Cultured MC derived from cord blood (CB)-CD34(+) cells proliferate well compared with those derived from adult CD34(+) cells; however, they have been reported to be phenotypically or functionally immature regardless of culture system. For example, very few cells express FcepsilonRI. To resolve this problem, we addressed the effect of human bone marrow stromal cell line on the development of cultured MC. CB-CD34(+) (1 x 10(4)) cells were cultured for 8 weeks in a serum-free medium containing rhIL-6 and rhSCF with or without a human bone marrow stromal cell line, namely, co-culture and liquid culture, and were compared in various regards. MC were basically determined by metachromatic staining of granules. The number of MC obtained (60.3 +/- 15.8 x 10(5) versus 2.0 +/- 1.0 x 10(5)), percentage of FcepsilonRI(+) cells (29.3 +/- 9.4% versus 1.9 +/- 0.8%), histamine content (9.7 +/- 2.8 pg/cell versus 5.8 +/- 2.3 pg/cell), and IgE-mediated histamine release (46 +/- 10% versus 17 +/- 7%) were higher (P < 0.01 and P < 0.05) in the co-culture than in the liquid culture. When CB-CD34(+) cells were developed in liquid culture with the co-culture supernatant (CM), a significant increase (P < 0.01) in the percentage of FcepsilonRI(+) cells and in cell number was observed but these values were lower than those of co-cultured MC. We concluded that this co-culture system was useful for obtaining a considerable number of mature MC with a high basal level of functional FcepsilonRI expression from CB-CD34(+) cells. Yet unknown humoral factors in CM may partly mediate this effect.

Abstract
Gastric enterochromaffin-like (ECL) cells release histamine in response to food because of elevation of gastrin and neural release of pituitary adenylate cyclase-activating peptide (PACAP). Acid secretion is at a basal level in the absence of food but is rapidly stimulated with feeding. Rats fasted for 24 h showed a significant decrease of mucosal histamine despite steady-state expression of the histamine-synthesizing enzyme histidine decarboxylase (HDC). Comparative transcriptomal analysis using gene expression oligonucleotide microarrays of 95% pure ECL cells from fed and 24-h fasted rats, thereby eliminating mRNA contamination from other gastric mucosal cell types, identified significantly increased gene expression of the enzymes histidase and urocanase catabolizing the HDC substrate L-histidine but significantly decreased expression of the cellular L-histidine uptake transporter SN2 and of the vesicular monoamine transporter 2 (VMAT-2) responsible for histamine uptake into secretory vesicles. This was confirmed by reverse transcriptase-quantitative polymerase chain reaction of gastric fundic mucosal samples from fed and 24-h fasted rats. The decrease of VMAT-2 gene expression was also shown by a decrease in VMAT-2 protein content in protein extracts from fed and 24-h fasted rats compared with equal amounts of HDC protein and Na-K-ATPase alpha(1)-subunit protein content. These results indicate that rat gastric ECL cells regulate their histamine content during 24-h fasting not by a change in HDC gene or protein expression but by regulation of substrate concentration for HDC and a decreased histamine secretory pool.

Abstract
Recent reports and our previous study suggest that mast cells play a crucial role in the pathological processes that follow cerebral ischemia. In this study, the effect of mast cells on neuron injury after cerebral ischemia was determined by adding in vitro ischemia-induced supernatant from mast cells to neurons and PC12 cells under the same conditions (oxygen-glucose deprivation, OGD). The degree of cell injury was evaluated by the 3-[4,5-dimethylthiazol-2-yl]-2,5-dipheny-ltetrazolium bromide (MTT) assay. Mast cell-derived supernatant protected against OGD-induced injury of PC12 cells and neurons, and this protection was reversed by a histamine H1 antagonist and by anti-histamine serum, but not by an H2 antagonist. However, histamine and nerve growth factor (NGF) added separately or together did not have protective effects against OGD-induced injury. These results indicate that mast cell-derived protection during in vitro ischemia is histamine-dependent, and involves cooperation with other mediators, but not NGF.

Abstract
BACKGROUND Allergen-mediated activation of the IgE signal pathway in basophils and mast cells leads to release of mediators in-vitro and in-vivo systems. However, basophils from 10% to 20% of the population do not release histamine and other mediators on activation of the IgE signal transduction pathway and this has been attributed to the absence of tyrosine kinases Lyn and Syk. Interestingly, when these non-releaser basophils are incubated with the IL-3, it leads to the recovery of the histamine releasibility. OBJECTIVE To investigate histamine releasibility in the Indian population and to evaluate the role of IL-3 with reference to non-releaser phenotypes. METHODS Peripheral blood basophils from healthy adults were purified by density gradient centrifugation and negative immuno-selection. Histamine release assay was performed fluorometrically. Assessment of Lyn and Syk expression were carried out by flow-cytometry. SNP analysis in the IL-3 gene was carried by sequencing analysis. RESULTS Histamine release after ConA challenge varied greatly from 0% to 100% in Indian subjects. Eighteen percent subjects showed less than 5% histamine release (non-releasers). Flow-cytometric analysis revealed a significantly reduced expression of Lyn and Syk kinases in basophils (p<0.05). Histamine release also significantly correlated with expression of Lyn and Syk kinase (p<0.05). Non-releasers showed the presence of SNP at +79 (T-C), which leads to the one amino acid change at 8th position in the mature IL-3 from serine to proline. CONCLUSIONS About 18% of the Indian subjects studied showed non-releaser phenotype and also had reduced Lyn and Syk kinase expression. Non-releasers have also shown the presence of less potent isoform of IL-3/P8, which is suspected to be responsible for the non-releaser phenotype. This needs to be extended to a larger sample size and could be a potential target for the development of therapeutics for allergic patients.

Abstract
In human airways mucosal mast cells are under the control of inhibitory muscarinic receptors. The described experiments tested, whether the inhibitory potency of two muscarinic receptor agonists (oxotremorine, acetylcholine) becomes impaired in advanced chronic obstructive pulmonary disease (COPD). Isolated human bronchi obtained from 26 patients with lung cancer were separated into two groups. Group 1 patients suffered from moderate COPD (mean FEV1 56%; range 34-71%; mean pack years of cigarette smoking 50, range 20-96; one non-smoker). Group 2 patients had no or only a mild form of COPD; mean FEV1 was 82% (62-97%) and the number of pack years 22 (6-45; 3 non-smoker). The calcium ionophore A23187 induced a maximal histamine release of 4100+/-870 pmol/g/5 min in group 1 bronchi, in contrast to only 1730+/-240 pmol/g/5 min in group 2 bronchi (p<0.02). Oxotremorine (1 nmol/L) reduced the stimulated histamine release by 81+/-5% in group 2 bronchi, but did not produce a significant effect in group 1 bronchi (11+/-14%). In conclusion, the present experiments show an enhanced histamine release in advanced COPD, which can be explained by a dysfunction of inhibitory muscarinic receptors.

Abstract
A role of IL-18 in the induction of gastric lesions by water immersion and restraint stress (WRS) was investigated. When wild-type BALB/c mice were exposed to WRS, levels of IL-18 in the serum and stomach increased rapidly with the development of acute gastric lesions. In IL-18-deficient mice [IL-18 knockout (KO) mice] similarly exposed to WRS, no gastric lesions were observed, but the administration of IL-18 before exposure to WRS resulted in the induction of WRS-induced gastric lesions. WRS enhanced gastric histidine decarboxylase (HDC) activity with concomitant increases in gastric histamine content. In IL-18 KO mice, the WRS-induced elevation of gastric HDC activity and histamine levels was much less than that in wild-type mice, but it was augmented by prior administration of IL-18. Treatment of wild-type mice with cimetidine, a histamine H2 receptor antagonist, inhibited the formation of WRS-induced gastric lesions with no effect on the induction of gastric IL-18 by WRS. Levels of corticosterone, one of the stress indicators, were lower in IL-18 KO mice than in wild-type mice. The glucocorticoid receptor antagonist mifepristone had no effect on gastric IL-18 and histamine levels but aggravated the stress-induced gastric lesions, indicating that corticosterone was not involved in the IL-18-mediated formation of stress-induced gastric lesions. These results indicate that IL-18 is involved in the induction of gastric lesions by WRS through augmentation of HDC activity and production of histamine in the stomach.

Abstract
A variety of cells, including fibroblasts, mast cells, macrophages, and ganglionic cells, are present in coronary artery adventitia. In the infarct-related coronary arteries of myocardial infarction patients, the majority of mast cells are found in the outer layer of the adventitia. Neurogenic stimulation of mast cells in the adventitia of coronary arteries may release vasoactive compounds, such as histamine and leukotrienes, which can contribute to the complex neurohormonal response that leads to abnormal coronary vasoconstriction. Lymphocytes and bacteria are also present mainly in the adventitial layer. Chlamydia pneumoniae is directly involved in the development of adventitial and plaque inflammation (pan-arteritis), leading to plaque rupture. Adventitial O(2)(-) may also play an extensive role in the control of vascular tone. Therefore, adventitial inflammation may play a pivotal role for atherosclerotic lesion development and atheroma instability.

Abstract
Allergy is the result of a complex immune cascade leading to the disregulated production of Th2 cytokines, the generation of allergen-specific IgE-producing B cells and the subsequent activation and degranulation of mast cells upon allergen challenge. Mast cell effector function significantly influences the quantity, duration and magnitude of most allergic reactions. Here, using isolated human umbilical cord blood mast cells (HUCBMC) from CD34+ cells, activated with anti-IgE (10 microg/ml) in culture, we found an augmented release of IL-6, tryptase and histamine (p < 0.01 compared with control). In addition, in these cells anti-IgE (10 microg/ml) activated the expression of histidine decarboxylase (HDC) and IL-6. In these studies we describe a new biological activity of anti-IgE in inducing histidine decarboxylase and IL-6, suggesting that this cytokine may have an important effect on allergic and inflammatory diseases mediated by mast cells. Moreover, with these data we confirm the immunoregulatory and inflammatory function of mast cells.

Abstract
Cardiac anaphylaxis refers to the functional and metabolic changes in the heart caused by the anaphylactic release of histamine and vasoactive products of arachidonic acid cascade by mast cells and basophils. As in most type I hypersensitivity-based diseases, histamine plays a key role in the pathophysiology of cardiac anaphylaxis. In the heart, mast cell activation and histamine release are controlled by multiple endogenous mechanisms, including adrenergic neural control, histamine-dependent negative feedback operated through H2 receptors, and the endogenous generation of nitric oxide (NO) and carbon monoxide (CO). All these mechanisms can be targeted by substances that have revealed a clear-cut effect in blunting cardiac anaphylaxis in experimental animal models, and could be developed as potential, novel anti-anaphylactic drugs. In this article, we discuss new findings and significant trends related to this topic.

Abstract
BACKGROUND Human lung mast cells (HLMC) lie in close proximity to the bronchial epithelium in asthma and adhere with high affinity to bronchial epithelial monolayers in vitro. We investigated the consequences of this adhesive interaction on HLMC activation in response to Fc epsilon RI cross-linking. METHODS Human lung mast cells were cultured with the bronchial epithelial cell line BEAS-2B or plastic control for either 30 min or 16 h and then activated with anti-IgE. Histamine was measured by radioenzymatic assay. RESULTS After co-culture for 30 min, IgE-dependent histamine release from HLMC was identical on both BEAS-2B and plastic. After 16 h of co-culture, there was a marked decrease in constitutive and IgE-dependent histamine release from HLMC cultured on BEAS-2B compared with those cultured on plastic or fibronectin. In contrast, the Ca(2+)/ATPase inhibitor thapsigargin produced concentration-dependent histamine release that was significantly increased on BEAS-2B compared with plastic. IgE-dependent degranulation was not significantly affected by BEAS-2B-conditioned medium. CONCLUSIONS BEAS-2B bronchial epithelial cells attenuate IgE-dependent but not thapsigargin-induced histamine release from HLMC. The differential effect with anti-IgE compared with thapsigargin suggests that the mechanism includes interference with the proximal Fc epsilon RI signalling pathway.

Abstract
BACKGROUND Immunoglobulin (Ig)E-sensitized persons with positive skin prick test, but no allergy symptoms, are classified as being asymptomatic skin sensitized (AS). The allergic type 1 disease is dependant on IgE binding to the high affinity IgE-receptor (FcepsilonRI) expressed on basophils and mast cells. However, a relationship between the AS status and FcepsilonRI has not been investigated. We aimed to characterize basophils from AS by looking at histamine release (HR) (sensitivity and reactivity) and the FcepsilonRI molecule, and compare it with nonatopic (NA) or allergic (A) persons. METHODS Blood was obtained from NA (n = 14), grass and/or birch A persons (n = 17) and mono-sensitized grass or birch pollen AS (n = 12). The basophil sensitivity and reactivity were examined by anti-IgE triggered HR. Surface expression of FcepsilonRI and IgE were measured by flow cytometry, FcepsilonRIalpha protein was identified using a radioimmunoassay and Western blot. mRNA coding for the classic FcepsilonRIbeta-chain and the truncated form (FcepsilonRIbetaT) were determined by real-time PCR. RESULTS The AS group was less reactive than NA or A persons when triggered by anti-IgE and had a significant higher number of nonresponders. However, there was no difference in sensitivity among the three groups and furthermore; the groups did not vary in FcepsilonRI- and IgE-surface expression, FcepsilonRIalpha-protein level or beta/betaT ratio. CONCLUSION Basophils from AS persons are less reactive and include more nonresponders than basophils from NA and A persons, but do not differ regarding the FcepsilonRI molecule.

Abstract
Chronic urticaria (CU) is a relatively common but vexing disease. The pathophysiology is based on the cutaneous mast cell release of mediators, predominantly histamine. Release can be induced via specific immunoglobulin E (IgE), components of complement activation and nonspecifically by various compounds including endogenous peptides, endorphins, and enkephalins. In >30% of CU patients, autoimmune phenomena have been found, characterized by positive autologous serum skin test, antibodies to the alpha-subunit of the basophil IgE receptor, to IgE itself, and, perhaps, the most clinically relevant, thyroid autoimmunity. Studies suggest that the products of the activated immune system can lower the cutaneous mast cell release threshold, possibly allowing activation by endogenous compounds. The resulting release of mediators produces the clinical picture of recurrent hives. Although the goal of management of CU is the identification of a treatable cause, in most CU patients, especially adults, a cause is not frequently found. Identified causes include drugs, foods, infections, immune complex production leading to urticarial vasculitis, autoantibody production, and underlying autoimmune disease, particularly autoimmune thyroiditis. The treatment of the thyroiditis with suppressive doses of thyroid hormone often results in the remission of the CU. Given the marginally effective and sometimes dangerous medical therapy available for CU, a systematic and thorough approach to identify a treatable cause in difficult CU patients is warranted.

Abstract
Role in pain sensation of both nociceptin (NC), the bioactive heptadecapeptide sequence of preproorphaninFQ and of histamine has been widely evidenced in the central nervous system (CNS). In the current series of experiments effect of intracerebroventricularly (i.c.v.) administered NC (5.5 nmol/rat) on histamine and serotonin levels in blood plasma, CSF and brain areas (hypothalamus and hippocampus) was studies and compared to the effect of the mast cell degranulator Compound 48/80(100microg/kg, i.c.v.) and the neuroactive peptide Substance P (50nmol/rat, i.c.v.). It was found that all the three compounds increased the histamine level in the CNS, however their activity concerning the mast cell-, and neuronal histamine release is different. NC could release histamine from both the mast cells and the neurons and it decreased CNS serotonin levels. Substance P was found the most potent in increasing CNS histamine levels. Compound 48/80 treatment resulted in elevated histamine levels both in the CNS and blood plasma. It is concluded that the histamine releasing effects of i.c.v. administered NC and SP are limited to the CNS, but in the effect of Compound 48/80 its blood-brain barrier impairing activity is also involved. Data also demonstrate that NC has significant effect on both the histaminergic and serotonergic neurotransmission in the CNS.

Abstract
BACKGROUND Recent studies have demonstrated relationships between cytokines and gastric acid secretion. The present study was performed in rats to elucidate the effects of interleukin-8 (IL-8) on gastric acid secretion through an increase in histamine release from the stomach. METHODS The experiments were performed in gastric lumen-perfused rats for the study of acid secretion and in totally isolated vascularly perfused rat stomach preparations for the study of histamine release. The histamine in the effluent was determined by radioimmunoassay. RESULTS IL-8 (500 ng) significantly enhanced gastrin-stimulated acid secretion. IL-8, at a concentration of 500 ng/20 ml per 10 min, did not alter basal histamine release, but at 100 ng/20 ml and 500 ng/20 ml it dose-dependently increased gastrin-stimulated histamine release. CONCLUSIONS IL-8 enhances gastrin-stimulated acid secretion and histamine release from the rat stomach, which may explain the enhancing effect of IL-8 on gastric acid secretion.

Abstract
Amphibian defensive skin secretions remain a largely untapped resource for the peptide biochemist with an interest in the identification, structural characterization, and precursor cDNA cloning of novel bioactive peptides. Here we report the isolation, structural characterization, functional profiling, and nucleotide sequence of precursor cDNA of a novel histamine-releasing heptadecapeptide, FIPVTLLALHKIKEKLN-amide, from the defensive skin secretion of the African running frog, Kassina senegalensis. This peptide was found to be a potent histamine secretagogue (EC(50) = 6 microM; maximal release = 25 microM) in a rat peritoneal mast cell model system and was accordingly named kassinakinin S. The open-reading frame of the cDNA encoding prepro-kassinakinin S was found to consist of 71 amino acid residues containing a single copy of kassinakinin S and its glycyl residue amide donor at the C-terminus. Kassinakinin S can thus be added to the growing list of amphibian skin bioactive peptide prototypes.

Abstract
Patients with food hypersensitivity suffer poor quality of life and several unexplained health complaints, both abdominal and extra-abdominal. Part of the suffering is due to healthcare providers' neglect and poor insight, allowing a strong position for alternative medicine. Distinguishing food allergy from functional and organic disorders can be extremely difficult. We have found examination of faecal calprotectin and gut permeability to be useful for excluding organic disease, whilst conventional provocation tests for positive diagnosis of food hypersensitivity are cumbersome. Our new ultrasound provocation test has been promising, but we acknowledge that much work remains to be done before its sensitivity and specificity can be finally established. The majority of patients with self-reported food hypersensitivity have a non-allergic hypersensitivity disorder. We suggest that cognitive-emotional sensitisation at the brain level, and not peripheral (immunological) sensitisation, is a major pathogenetic mechanism by which the patients' various abdominal and extra-abdominal health complaints are generated. Extensive activation of cognitive networks might be triggered by peripheral sensory mechanisms, often misinterpreted as 'food allergy'. Clearly, the approach to patients with food hypersensitivity should be interdisciplinary.

Abstract
In this study, we identify the bidirectional organic cation transporter 3 (OCT3/Slc22a3) as the molecule responsible for histamine uptake by murine basophils. We demonstrate that OCT3 participates in the control of basophil functions because exogenous histamine can inhibit its own synthesis--and that of interleukin (IL)-4, IL-6, and IL-13--through this means of transport. Furthermore, ligands of H3/H4 histamine receptors or OCT3 inhibit histamine uptake, and outward transport of newly synthesized histamine. By doing so, they increase the histamine content of basophils, which explains why they mimic the effect of exogenous histamine. These drugs were no longer effective in histamine-free histidine decarboxylase (HDC)-deficient mice, in contrast with histamine itself. Histamine was not taken up and lost its inhibitory effect in mice deficient for OCT3, which proved its specific involvement. Intracellular histamine levels were increased strongly in IL-3-induced OCT3-/- bone marrow basophils, and explained why they generated fewer cytokines than their wild-type counterpart. Their production was enhanced when histamine synthesis was blocked by the specific HDC inhibitor alpha-fluoro-methyl histidine, and underscored the determinant role of histamine in the inhibitory effect. We postulate that pharmacologic modulation of histamine transport might become instrumental in the control of basophil functions during allergic diseases.

Abstract
OBJECTIVE Mast cells play pivotal roles in immediate-type and inflammatory allergic and nonallergic reactions. Cross-linking of the high-affinity receptor for IgE (FcepsilonRI) on mast cells activates a signaling pathway leading to Ca2+ mobilization and is followed by degranulation and the release of histamine and other preformed mediators, as well as de novo synthesis of arachidonic acid metabolites. In a previous study, we have demonstrated that heat shock activates heat shock transcription factor-1 (HSF-1), induces heat shock protein 70 (HSP70), and suppresses cytokine production in bone marrow-derived mast cells (BMMC). In this study, we further investigated the effects of heat shock on the activation of mast cells and the release of mast cell mediators. METHODS In mouse mast cells, derived from a culture of bone marrow cells of male BALB/cBy and null HSF-1(-/-)mice, responsiveness to heat shock was monitored by measuring beta-hexosaminidase and leukotriene C4 (LTC4) release. RESULTS Using BMMC, we found that heat shock inhibits degranulation of BMMC without affecting leukotriene production. To further elucidate the mechanism of suppression of degranulation, we studied the effects of heat shock on the regulation of signal transduction in more detail. We found that heat shock inhibits calcium mobilization and tyrosine phosphorylation of Syk and SHIP upon IgE receptor activation, but increases the phosphorylation of SHP-1 and -2. Moreover, our results revealed that suppression of tyrosine phosphorylation of Syk and SHIP coincided with an increased tyrosine phosphatase activity. CONCLUSION The inhibitory action of heat shock toward mast cell degranulation is likely due to shifting the balance between kinase and phosphatase activity.

Abstract
BACKGROUND In the early phase response of allergic rhinitis, the nasal mucosa produces important mediators including histamine and leukotrienes. OBJECTIVE To investigate the relationship between antigen-induced leukotriene release and histamine secretion in nasal scrapings. METHODS Using nasal mucosal scrapings from patients sensitized to only house dust mite, we studied the time course of antigen-induced leukotriene release and its relationship to histamine release. RESULTS Cumulative peptydyl leukotriene (LT) production from nasal scrapings increased from 10 min to approximately 90 min following exposure to mite antigen. The rate of LT release was small (<5 pg/10 min) until 10 min following antigen exposure, increased to approximately 250 to 350 pg LT/10 min from 10 to 45 min post exposure, was reduced to <100 pg/10 min by 60 to 150 min, and by 180 min LT production was negligible. By contrast, histamine secretion began 30 sec after antigen exposure and was complete within approximately 10 min. Net antigen-induced LT secretion strongly correlated (R=0.72) with net antigen induced histamine secretion with a ratio of 1:8.7. In addition, net LT/ng histamine and total LT secretion correlated well with antigen-specific IgE in serum, and with the patients' symptoms. CONCLUSION There is a close relationship between amounts of histamine and LT secretion from antigen challenged nasal mucosa, although the time course of LT release is delayed. In the early phase response, LT are likely to be generated from mucosal mast cells, and thus, mast cell activation will provide an important therapeutic target.

Abstract
The purpose of this study was to investigate the effect of oxygen-glucose deprivation (OGD) on degranulation and histamine release of mast cells. Cultured mast cells were exposed to OGD for 1, 2, 4, 8, or 16 h. At 2 h of OGD exposure, the degranulation percentage of mast cells had increased and subsequently showed a progressive further increase, associated with a similar change in lactate dehydrogenase release. Histamine release increased significantly from 1 h of OGD exposure. These results indicate that OGD induces mast cells to degranulate, possibly via a cytotoxic response. This in vitro ischemic model of mast cells might clarify their roles in the pathological processes induced by cerebral ischemia.

Abstract
Infection with Salmonella typhimurium can produce multiple organ dysfunctions. However, document concerning with gastric hemorrhagic ulcers occur in this infectious disease is lacking. The aim was to study modulation of gastric hemorrhagic ulcer by oxidative stress and mast cell histamine in S. typhimurium-infected rats. Additionally, the protective effects of drugs, such as ofloxacin, lysozyme chloride, ketotifen, ranitidine, and several antioxidants, including exogenous glutathione (GSH), allopurinol and dimethylsulfoxide (DMSO) were evaluated. Male Wistar rats were injected intrajejunally with a live culture of S. typhimurium (1 x 10(10) colony-forming units/rat) and followed by deprivation of food for 36 h. Age-matched control rats received sterilized vehicle only. Rat stomachs were irrigated for 3 h with either normal saline or a simulated gastric juice containing 100 mM HCl, 17.4 mM pepsin and 54 mM NaCl. S. typhimurium caused aggravation of offensive factors, including enhancing gastric acid back-diffusion, mucosal lipid peroxide generation, histamine release, microvascular permeability and hemorrhagic ulcer, as well as an attenuation of defensive substances, such as mucosal GSH and mucus level. Intragastric irrigation of gastric juice caused further aggravation of these gastric biochemical parameters. This exacerbation of ulcerogenic factors was abolished by pretreatment of ofloxacin and lysozyme chloride. Antioxidants, such as reduced GSH, allopurinol and DMSO also produced significant (P < 0.05) amelioration of gastric damage in S. typhimurium infected rats. In conclusion, gastric oxidative stress and histamine play pivotal roles in the formation of hemorrhagic ulcers that were effectively ameliorated by ofloxacin, lysozyme chloride, ketotifen, ranitidine, diamine oxidase and various antioxidants in S. typhimurium-infected rats.

Abstract
In the present study, the impact of acquired neoplastic L-histidine decarboxylase (HDC) expression, and its direct consequence, the release of histamine in the tumor environment, was assessed on melanoma tumor progression. B16-F10 mouse melanoma cells were manipulated via stable transfection, and nine novel transgenic variants were generated in triplicates, constitutively expressing the full-length sense mouse HDC mRNA, a mock control, and an antisense HDC RNA segment, respectively. Establishing both primary skin tumors and lung metastases in C57BL/6 mice, the nine variants with different histamine-releasing capacities were subjected to a comprehensive comparative progression profiling in vivo. Our analyses showed trends of markedly accelerated tumor growth (P < 0.001), and moderately increased metastatic colony-forming potential (P = 0.010) along with rising levels of local histamine production. Using RNase protection assay for screening of the melanoma progression profile, and Western blotting for subsequent result validation, we looked for molecular progression markers affected by melanoma histamine secretion. Investigation of 21 functionally clustered markers associated with tumor proliferation, angiogenesis, invasivity, metastasis formation, local or systemic immunomodulation, and histamine signaling revealed positive correlations between histamine production, tumor histamine H2 receptor and rho-C expression (P < 0.001, P = 0.002, respectively). These observations confirm the involvement of histamine in the molecular machinery of melanoma progression.

Abstract
We studied the effect of Lo Han Kuo (Siraitia grosvenori Swingle) on histamine-induced nasal rubbing and compound 48/80-induced skin scratching behavior in ICR mice. An extract and glycoside (a complex of sweet components) of Lo Han Kuo were used in the study. Both the extract and glycoside caused no significant effect on nasal rubbing or scratching behavior, even at a dose of 1000 mg/kg when administered in a single dose. However, the effect of Lo Han Kuo became clear after repeated administration, and 300 and 1000 mg/kg of both extract and glycoside significantly inhibited nasal rubbing and skin scratching behavior after consecutive treatment for 4 weeks. Both the extract and glycoside inhibited the histamine release induced by compound 48/80 at concentrations of 300 and 1000 microg/ml. From these results, it is assumed that the inhibition of nasal rubbing and skin scratching behavior induced by Lo Han Kuo occurs through a mast cell-dependent mechanism.

Abstract
To resolve the controversy regarding substance P (SP) mediated stimulation of mast cells (MC), we demonstrate that SP triggers histamine release from purified human skin MC (sMC), but contrast to stimulation via FcepsilonRI, does not effect the production of TNF-alpha or IL-8. Conversely, both anti-IgE and SP are suppressive in terms of IL-6. By quantitative RT-PCR, the amount of templates at baseline (per 25 ng total RNA) is 2178 (IL-6), 2,665 (IL-8) and 94 (TNF-alpha), and remains unaltered by SP. Contrast to sMC, LAD2 MC respond to SP with stronger histamine release and robust TNF-alpha production in an only partially neurokinin-1R mediated manner, while histamine release of sMC is chiefly mediated by this receptor. We conclude that human sMC are responsive to SP in a selective manner by eliciting degranulation without the induction of cytokines and that SP-triggered cytokine production varies among MC subtypes, likely through differences in signaling mechanisms.

Abstract
The ECL cells in the oxyntic mucosa secrete histamine in response to gastrin, stimulating parietal cells to produce acid. Do they also operate under nervous control? The present study examines histamine mobilization from rat stomach ECL cells in situ in response to acute vagal excitation and to food or gastrin following vagal or sympathetic denervation. Applying the technique of microdialysis, we monitored the release of histamine by radioimmunoassay. Microdialysis probes were placed in the submucosa on either side of the stomach, 3 days before experiments. The rats were awake during microdialysis except when subjected to electrical vagal stimulation. One-sided electrical vagal stimulation raised serum gastrin and mobilized gastric histamine. However, gastrin receptor blockade prevented the histamine mobilization, indicating that circulating gastrin accounts for the response. Vagal excitation by hypoglycaemia (insulin) or pylorus ligation did not mobilize either gastrin or histamine. The histamine response to food was almost abolished by gastrin receptor blockade, and it was halved on the denervated side after unilateral subdiaphragmatic vagotomy. While the histamine response to a near-maximally effective dose of gastrin was unaffected by vagotomy, the response to low gastrin doses was reduced significantly. Abdominal ganglionic sympathectomy failed to affect the histamine response to either food or gastrin. In conclusion, gastrin is responsible for most of the food-evoked mobilization of ECL-cell histamine. The histamine response to electrical vagal stimulation reflects the effect of circulating gastrin rather than a direct action of the vagus on the ECL cells. Vagal denervation was accompanied by an impaired histamine response to food intake, probably reflecting the right-ward shift of the serum gastrin concentration-histamine response curve. The results suggest that the vagus controls the sensitivity of the ECL cells to gastrin.

Abstract
Herein we investigate the ability of live promastigotes and total lysate of Leishmania (Viannia) braziliensis, derived from parasites in the logarithmic (L-Lb) or stationary phase (S-Lb), to induce human mast cell line (HMC-1) activation. In comparison with medium-treated cells, a significant histamine release was observed in HMC-1 cultures stimulated with S-Lb. Lipophosphoglycan also induced histamine release by HMC-1 cells. In immunocytochemical assays, we found a marked staining for tryptase in medium-treated HMC-1 cells, however, stimulation with L-Lb or S-Lb caused a marked decrease in the color reaction as well as in the number of tryptase-positive cells. L-Lb and S-Lb induced an evident decrease in the intracellular expression of IL-4 but not IL-12. Live stationary promastigotes were able to induce high levels of IL-4 release in HMC-1 cultures. Furthermore, these cells released significant amounts of IL-12 when incubated with both types of live promastigotes. These results indicate that L. (V.) braziliensis promastigotes differ in their ability to induce direct human mast cells activation, according to the growth phase of the parasite. Furthermore, the release of pro-inflammatory mediators and cytokines could represent an important phenomenon that might favor the initial establishment of the infection.
