Abstract
Mast cells are present in all vascularized tissues of the body. They are especially abundant in tissues that are in frequent contact with the surrounding environment and act as potential sources of inflammatory and/or regulatory mediators during development of various infections and diseases. Mature mast cells’ cytoplasm contains numerous granules that store a variety of chemical mediators, cytokines, proteoglycans, and proteases. Mast cells are activated via various cell surface receptors, including FcϵRI, toll-like receptors (TLR), Mas-related G-protein-coupled receptor X2 (MRGPRX2), and cytokine receptors. IgE-mediated mast cell activation results in release of histamine and other contents of their granules into the extracellular environment, contributing to host defense against pathogens. TLRs, play a crucial role in host defense against various types of pathogens by recognizing pathogen-associated molecular patterns. On the other hand, excessive/inappropriate mast cell activation can cause various disorders. Here, we review the published literature regarding the known and potential inflammatory and regulatory roles of mast cells in cutaneous inflammation, including atopic dermatitis, psoriasis, and contact dermatitis GVHD, as well as in host defense against pathogens.

Abstract
Flavonoids, found in almost all fruits and vegetables, belong to a class of plant secondary metabolites with a polyphenolic structure and have properties with health-improving potential. However, few experimental studies on the effects of flavonoids have been carried out in vivo after external application and using pure compounds. Aiming to fill this gap, in this study we tested the topical anti-inflammatory and antiallergic activity of three flavonoids of high purity, naringenin, naringenin chalcone, and quercetin, in mouse models. The topical anti-inflammatory effects were assessed against arachidonic acid- (AA) and tetradecanoylphorbol-13-acetate- (TPA) induced ear edema. The anti-inflammatory effect of naringenin against ear edema was noticeable at a 1% dose in the AA model and at half this dose in the TPA model. Quercetin (1.3%) did not exert any topical anti-inflammatory activity in the AA model, but its inhibitory effect in the TPA model was similar to that of naringenin (2%); in contrast, naringenin chalcone was more active against the AA-induced than TPA-induced inflammation. The flavonoid effect on IgE-mediated passive cutaneous anaphylaxis was also studied in mice, both intravenously and topically. Naringenin, naringenin chalcone, and quercetin all showed strong antiallergic activity after intravenous dosing (0.02%) and when applied topically (2%). The results of this study suggest that the flavonoids naringenin, naringenin chalcone, and quercetin may be useful alternatives for the topical treatment of inflammatory and allergic skin disorders.

Abstract
Epidemiological studies suggest increased fracture risk in patients using proton pump inhibitors (PPIs). We have previously shown that the H(+) /K(+) ATPase beta subunit knockout (KO) mouse, which is a model of PPI-use, have lower bone mineral density (BMD) and impaired bone quality compared to wild type (WT) mice. Like PPI users, these KO mice display elevated gastric pH and hypergastrinemia, which in turn stimulates gastric histamine release. Previous studies have suggested a negative effect of histamine on bone, thus, we wanted to study whether a histamine 1 receptor (H1R) antagonist could improve bone quality in KO mice. Female KO and WT mice aged 8 weeks received either an H1R antagonist (cetirizine) or polyethylene glycol (PEG) for 6 months. At the end of the study, KO mice displayed elevated plasma histamine levels compared to WT. As demonstrated previously, the KO mice also exhibited lower whole body BMD, reduced mechanical bone strength, and impaired bone quality assessed by μCT. No significant differences, however, were found between the KO groups receiving cetirizine or PEG for any of the measured bone parameters. In vitro gene expression analyses of histamine receptors revealed the presence of H1R and H2R both in osteoblasts and osteoclasts, and H3R in late stage osteoblasts. In conclusion, administration of the H1R antagonist cetirizine in a concentration of 3 mg/kg did not rescue the osteoporotic phenotype in H(+) /K(+) ATPase beta subunit KO mice. It can, however, not be ruled out that histamine may influence bone via other receptors. J. Cell. Biochem. 117: 2089-2096, 2016. © 2016 Wiley Periodicals, Inc.

Abstract
Mast cells are known as effector cells of IgE-mediated allergic responses, but role of mast cells in contact hypersensitivity (CHS) has been considered controversial. In this study, we investigated role of mast cell in trimellitic anhydride (TMA)-induced CHS. The mice were sensitized to TMA on the back and repeatedly challenged with TMA on the left ear at 1-week intervals. The ear after challenge showed biphasic responses. The repetition of TMA challenge shifted in time course of ear response and enlarged the extent of early and late phase reactions in proportion to the frequency of TMA challenges in C57BL/6 mice. In late phase reaction, peak of ear response by single challenge showed at 24 hours after challenge, but the peak by repeat challenges at 8 hours after the last challenge. Number of mast cells and eosinophils per unit area increased in proportion to frequency of TMA challenges. However, mast cell-deficient WBB6F1/J-KitW/KitW-v mice developed the late phase reaction without the early phase reaction. The repetition of TMA challenge shifted in time course of ear response and enlarged the extent of ear response and the infiltration of eosinophils. The magnitude of these responses observed according to the frequency of the TMA challenge in mast cell-deficient WBB6F1/J-KitW/KitW-v mice was significantly lower than that in C57BL/6 mice. Also TMA elicited mast cell degranulation and histamine release from rat peritoneal mast cells in a concentration-dependent manner. Conclusively, TMA induces the early and late phase reactions in CHS, and mast cells may be required for TMA-induced CHS.

Abstract
The aim of the current study was to investigate the involvement of tryptase and protease-activated receptor-2 (PAR2) in the pathogenesis of itch using a recently developed murine model of atopic dermatitis (AD) elicited by epicutaneous sensitization with ovalbumin (OVA). We also examined whether tacrolimus exerts an antipruritic effect. Epicutaneous sensitization of BALB/c mice with OVA led to a significant increase in the number of scratches. Notably, PAR2 mRNA and protein levels as well as cutaneous levels of tryptase were significantly enhanced in epicutaneously sensitized mice. Pretreatment with the protease inhibitor, leupeptin, PAR2 antibody, and tacrolimus significantly reduced the number of degranulated mast cells and tryptase content, and consequently alleviated scratching behavior. Cetirizine (10mg/kg) exerted a significant inhibitory effect on the scratching behavior of mice, but did not affect the number of degranulated mast cells and induction of tryptase. Our results collectively suggest that tryptase and PAR2 are involved in OVA allergy-induced scratching behavior.

Abstract
Involvement of cannabinoid CB2 receptors in the IgE-mediated cutaneous reaction was investigated. Epicutaneous challenge with 2,4-dinitrofluorobenzene caused a triphasic swelling in the ear of BALB/c and C57BL/6 mice passively sensitized with anti-dinitrophenol IgE. Peak responses of the ear swelling appeared at 1 h, 24 h, and 8 days after the challenge in both strains of mice. In contrast, cannabinoid CB2 receptor-deficient mice failed to exhibit the obvious triphasic ear swelling observed in wild-type mice. Oral administration of cannabinoid CB2 receptor antagonist/inverse agonists [N-(benzo[1,3]dioxol-5-ylmethyl)-7-methoxy-2-oxo-8-pentyloxy-1,2-dihydroquinoline-3-carboxamide] (JTE-907) and {N-[(1S)-endo-1,3,3-trimethylbicyclo[2,2,1]heptan-2yl]5-(4-chloro-3-methyl-phenyl)-1-(4-methylbenzyl)pyrazole-3-carboxamide} (SR144528) at doses of 0.1-10 mg/kg significantly and dose-dependently suppressed all three phases of ear swelling in BALB/c mice. Interestingly, epicutaneous treatment with an ether-linked analogue of endogenous cannabinoids, 2-arachidonoylglycerol, caused an ear swelling that could be detected at 1 h, 24 h, and 8 days after treatment of both BALB/c and C57BL/6 mice. These results suggest that cannabinoid CB2 receptors are involved in induction of the triphasic cutaneous reaction mediated by IgE, and that cannabinoid CB2 receptor antagonist/inverse agonists may serve as anti-allergic agents in the treatment of allergic dermatitis.

Abstract
Phellinus linteus, a mushroom, contains constituents that exhibit potent antitumor effects through activating immune cells. Recently, anti-inflammatory and anti-allergic properties of P. linteus extracts have also been implicated. In the present study, therefore, we separated the constituents of mycelium of P. linteus into five fractions—chloroform-soluble (CF), ethyl acetate-soluble (EA), methanol-soluble (AE), water-soluble (WA) and boiling water-soluble (BW) fractions—and examined their suppressive effects on the IgE-dependent mouse triphasic cutaneous reaction. The triphasic reaction was induced in the ear of BALB/c mice passively sensitized with anti-dinitrophenol IgE by painting with 2,4-dinitrofluorobenzene 24 h later. Ear swelling appeared triphasically with peak responses at 1 h, 24 h and 8 days after the challenge. ME, WA and BW given orally at a dose of 100 mg kg−1 significantly inhibited the first and second phase ear swelling, and BW also inhibited the third phase response. CF only inhibited the second phase. The inhibition by BW was the most potent and almost dose-dependent at doses of 30–300 mg kg−1. BW also inhibited vascular permeability increase caused by passive cutaneous anaphylaxis and histamine, and ear swelling caused by tumor necrosis factor-α. In contrast, BW apparently potentiated the production of interleukin-4 and interferon-γ from anti-CD3-stimulated mouse splenocytes. These results indicate that BW derived from mycelium of P. linteus contains some constituents with anti-allergic as well as immunopotentiating properties.

Abstract
Antihistamines are useful medications for the treatment of a variety of allergic disorders. Second-generation antihistamines avidly and selectively bind to peripheral histamine H1 receptors and, consequently, provide gratifying relief of histamine-mediated symptoms in a majority of atopic patients. This tight receptor specificity additionally leads to few effects on other neuronal or hormonal systems, with the result that adverse effects associated with these medications, with the exception of noticeable sedation in about 10% of cetirizine-treated patients, resemble those of placebo overall. Similarly, serious adverse drug reactions and interactions are uncommon with these medicines. Therapeutic interchange to one of the available second-generation antihistamines is a reasonable approach to limiting an institutional formulary, and adoption of such a policy has proven capable of creating substantial cost savings. Differences in overall efficacy and safety between available second-generation antihistamines, when administered in equivalent dosages, are not large. However, among the antihistamines presently available, fexofenadine may offer the best overall balance of effectiveness and safety, and this agent is an appropriate selection for initial or switch therapy for most patients with mild or moderate allergic symptoms. Cetirizine is the most potent antihistamine available and has been subjected to more clinical study than any other. This agent is appropriate for patients proven unresponsive to other antihistamines and for those with the most severe symptoms who might benefit from antihistamine treatment of the highest potency that can be dose-titrated up to maximal intensity.

Abstract
Intradermal injection of human chymase (EC 3.4.21.39) into the mouse ear elicited an edematous skin reaction in a biphasic manner, with a transient reaction peaking at 1 hr, followed by a delayed response persisting for at least 24hr. The kinetics of this reaction was analogous to the biphasic skin reaction induced by ascaris extract in actively sensitized mice. A similarity between the two dermatitis models was also shown by histological analysis, i.e. accumulation of inflammatory cells was observed exclusively in the later phases of the skin reaction. A chymase inhibitor, SUN-C8077 [3-(3-aminophenylsulfonyl)-7-chloroquinazorine 2,4(1H, 3H)-dione], significantly inhibited both the early- and late-phase responses of the skin reaction induced by ascaris extract. These findings suggest that chymase may play an important role in the allergen-induced biphasic skin reaction. A histamine receptor antagonist, homochlorcyclizine, inhibited the early-phase but not the late-phase of the chymase-induced skin reaction. In addition, human chymase showed chemotactic activity to human polymorphonuclear leukocytes in vitro. Mast cell chymase may participate in the two phases of allergic skin inflammation by two distinct mechanisms, i.e. histamine- and leukocyte-dependent mechanisms, respectively.

Abstract
Antihistamines are drugs which act by competitive inhibition of the H1 or H2 histamine receptors. Little has been known about their clinical pharmacokinetics and biological responses until the last few years. In this paper, we propose quantitative retention-activity relationship, QRAR, models based on the retention data of antihistamines in a biopartitioning micellar chromatography (BMC) system using a Brij35 mobile phase for describing pharmacokinetic parameters such as half-life and volume of distribution, or the pharmacodynamic parameters, therapeutic plasma levels, lethal doses and drug-receptor dissociation constant. The predictive ability of these models is statistically validated. These results are compared to traditional quantitative structure-activity relationship, QSAR, models using lipophilicity data. The adequacy of QRAR models can be explained taking into account the fact that the retention of compounds in BMC depends on their hydrophobic, electronic and steric characteristics which are of great importance in pharmacokinetic and pharmacodynamic behavior.

Abstract
Anti-scratch effects of oxatomide and epinastine were examined in mice. Scratching behavior and cutaneous reactions were induced in BALB/c, ICR and ddY mice by dinitrofluorobenzene painting, passive cutaneous anaphylaxis and substance P injection, respectively. Although oxatomide and epinastine failed to inhibit scratching behavior in BALB/c mice, they inhibited the cutaneous reaction significantly. The drugs potently inhibited both scratching behavior and cutaneous reaction in ICR mice. They also inhibited scratching behavior and cutaneous reaction in ddY mice, although cetirizine and terfenadine failed to affect them. Histamine did not induce frequent scratching behavior in BALB/c and ddY mice. These results indicate that oxatomide and epinastine inhibit the scratching behavior in ICR mice associated with passive cutaneous anaphylaxis mainly through an antagonistic action on histamine H(1) receptors. The results also indicate that these drugs inhibit substance P-induced scratching behavior in ddY mice through an action independent of the antagonistic action on histamine H(1) receptors.
