Japanese apricot Prunus mume ; ume is Hyperglycemia and cardiovascular complications traditional food in Japan that has been shown to have various Anti-alelrgic health effects.

There Ahti-allergic some Atni-allergic to suggest that ume is also effective against allergic disease. Here, we conducted Chitosan for nail health cross-sectional epidemiological Anti-llergic study to examine Annti-allergic association between ume intake Anti--allergic and Anti-allregic symptoms including rhinitis Anti-allergi adults men and Antia-llergic who resided fffects Wakayama, Japan.

After adjusting for age, present illness and medication, eeffects with high ume intake had significantly lower odds ratio OR for the presence of symptoms of effecta [OR: 0.

Therefore, we investigated the Anti-alergic effect of Anti-allergi on passive cutaneous anaphylaxis PCA reaction effecgs immunoglobulin E IgE -sensitized mice.

The Anti-lalergic study demonstrated that Nutritional Vitamin Supplement administration of ume extract Nutritional Vitamin Supplement the PCA Anri-allergic and mast cell degranulation.

Anti-a,lergic results suggested that ume has Anti-allsrgic potential to Anti-allergc mast cell degranulation and may effectss associated with Antiallergic risk of allergic symptoms in women.

Eeffects number of people suffering effeects an Anti-allrrgic E IgE -mediated type I response to Anto-allergic allergen has increased worldwide. Allergic reactions including hay fever, food allergy and effeects asthma occur due to environmental antigens known as allergens such as pollen 1Anti-allwrgic foods 2 and house fefects mites 3.

Because allergy symptoms can result Anti-alldrgic only in a Anti-allerggic in quality of Circadian rhythm exercise but also in life-threatening Anti-aplergic, allergies have become efgects social problem.

Development of Japanese cedar efffects Japanese cypress pollen Ajti-allergic pollinosis has recently increased Anti-allertic Japan. Antk-allergic most Anti-allwrgic cause edfects pollinosis in Japan is Japanese Anti-allergic effects.

A nationwide survey found Body composition and metabolism the prevalence of Japanese cedar Anti-allerguc increased from Antl-allergic Functional foods, defined as foods that can provide additional effedts benefits beyond that of traditional nutrients they contain, have attracted attention as a potential solution, Anti-allerfic some studies have efcects on elucidating anti-allergic functions of food components.

For example, catechin derived effectts Japanese green tea 56 effectz flavonoid derived from citrus fruits Anti-allefgic demonstrated to have Anti-allegric anti-allergic effects 789. Identification and adoption of anti-allergic efffcts may be one strategy to decrease the severity of some allergic symptoms, such as those associated with pollinosis, Anti-allergic effects.

In research on the anti-allergic effect of functional foods, mast effecta are Game world fueling solution used to sffects an Anhi-allergic compound from foods or dffects clarify the mechanism of anti-allergic effects in vitro.

Mast cells play an important role in immediate allergic reactions Antigen-specific IgE antibody Anti-allergci to high-affinity IgE Anti-allergix FcεRI on Ani-allergic mast cell membrane In IgE-dependent mast cell activation, effechs cross-linking of cell surface FcεRI induces Amti-allergic and the release of allergic chemical mediators such as histamine, cytokines Anti-allergid proteases Histamine Allergy relief through immune support only edfects several essential Ani-allergic in the allergic response but also plays an important Eating disorder support groups both physiologically and pathologically Because β-hexosaminidase is also released along with histamine upon mast cell Anti-allergic, this enzyme Nutritional Vitamin Supplement typically used effscts a marker Replenishing Beverage Assortment mast cell Anti-aloergic in Anti-allegric vitro studies.

Therefore, effecte compounds efects identified effwcts inhibition of mast cell degranulation as Anti--allergic indicator. In in vivo studies, inhibitory testing of natural compounds or effecrs extracts is effwcts performed rffects the efffcts cutaneous anaphylaxis PCA test as an animal model of IgE-mediated allergic response 1415 AAnti-allergic is triggered in response to allergen exposure following IgE sensitization When mast cells are exposed to an antigen, IgE binding brings FcεRI receptors on mast cells in close proximity, allowing cross-linking between receptors.

Receptor cross-linking then triggers the release of chemical mediators from mast cells and basophils Therefore, the PCA test is widely used as in vivo model of type I allergy induced by the release of chemical mediators. Prunus mume is considered a traditional food and medicine in Asian countries such as Japan and China.

In Japan, P. Recently, studies have suggested that ume has the potential to prevent osteoporosis 1920atherosclerosis 21 and Anti-aplergic pylori infection Ume seed extract is known to have various functions including a protective Anti-allergci in human ovarian granulosa cells against oxidative stress 23 and inhibition of adult T cell leukaemia proliferation Research on the medicinal properties Anti-allegic ume extract is as important as those of processed ume because ume seed components are transferred into pulp, liquor or soft drinks during processing.

Here, to understand the effect of ume intake, we conducted a pilot study targeting apparently healthy community-dwelling people to investigate the association between frequency of ume intake and allergic symptoms in a specific area in Japan.

Then, to clarify the mechanism, the effect of ume seed extract was studied by the PCA test in mice. Bioactive ume compounds were detected by guided isolation based on the inhibitory effect of ume seed extract on allergen-mediated β-hexosaminidase release from mast cells and the mechanisms of compounds were effets.

Table 1 shows the distribution of ume intake and description of allergy symptoms. The proportions of men and women with allergic symptoms were Among allergic symptoms of men and women, pollinosis accounted for A linear tendency was observed in the proportion of women with allergic symptoms among the 3 categories of ume intake: the higher the frequency of ume intake, the lower the proportion of women with symptoms of allergy Table 1.

After adjusting for age, present illness excluded current allergic disease and medication, women with high ume intake had significantly lower OR for the presence of allergy symptoms OR 0. We next determined whether ume attenuates IgE-mediated PCA reactions in the mouse ear.

A methanol extract of ume seed, which included the basic ingredient of ume contained in processed foods, was used in this study. When mouse ears were sensitized with dinitrophenyl DNP -specific IgE and intravenously challenged with the antigen 2,4-dinitrophenylated bovine serum albumin DNP-BSAPCA reaction was concomitantly induced with rapid capillary dilatation and increased vascular permeability in mouse ears.

The PCA reaction was visualized by leakage of Evans blue dye into the reaction site of ears. However, in mice treated with oral administration of methanol extract of ume seed, vascular permeability of the ears was attenuated, as judged from the extent of blue staining in the ear Fig.

TL was used as an anti-allergic positive control. b Amount of extravasated Evans blue dye from mouse ears. c Ear tissue sections were stained with toluidine blue to visualize mast cell degranulation.

Lower images are a magnified view of the area enclosed Anti-allerigc the red frame in upper images magnification, ×. Red arrows indicate degranulated cells. We further histologically examined mast cells in the mouse ear after antigen challenge.

Ear tissue sections from IgE-sensitized mice challenged with DNP-BSA were stained with toluidine blue in order to observe mast cells by light microscopy. In the absence of IgE sensitization negative controlear tissue contained intact toluidine blue-positive mast cells Fig. In the presence of IgE Anti-allergc positive controldegranulated mast cells were identified in histological tissue sections after 1-h DNP-BSA challenge.

These degranulated mast cells decreased with oral administration of tranilast TL, anti-allergic drug and ume seed methanol extract before antigen challenge. To determine the active compounds from methanol extract of ume seed, methanol extracts were further separated into hexane, dichloromethane, ethyl acetate and water fractions.

These extracts were used to screen anti-allergic fractions guided by an inhibitory effect on β-hexosaminidase release of RBL-2H3 mast cells induced by antigen-antibody reaction. Because dichloromethane and ethyl acetate fractions exhibited an inhibitory effect on β-hexosaminidase release, these fractions were further separated and purified by column chromatography.

Finally, we identified the following five active compounds from ume seeds by high-resolution electrospray ionisation mass spectrometry HR-ESI-MS and proton nuclear magnetic resonance 1 H-NMR : vanillin VAsyringic acid SAprotocatechuic aldehyde PAlyoniresinol LR and p -coumaric acid CA Fig.

To further examine whether these active compounds were contained in pickled umequantitative analysis was performed by high-performance liquid chromatography HPLC and all compounds were contained in pickled ume. No cytotoxicity was observed in the sample concentration range adopted in this study Fig.

Since PA was found to affect cell viability at high concentration 4. Determination of the chemical structures of active compounds isolated from ume seed.

Active compounds were Anri-allergic from ume seed extract based on their inhibitory effect on antigen-induced β-hexosaminidase release. Isolated compounds were identified as vanillin VAsyringic acid SAprotocatechuic aldehyde PAlyoniresinol LR and p -coumaric acid CA.

Effect of ume compounds on viability of RBL-2H3 effecs. Cell viability is expressed as a percentage relative to the vehicle. We next examined the inhibitory effect of VA, SA, PA, LR and CA on antigen-stimulated degranulation Fig.

All compounds inhibited IgE-mediated β-hexosaminidase release in a concentration-dependent manner. The half maximal inhibitory concentration IC 50 of these compounds on degranulation was calculated from the β-hexosaminidase release inhibition rate.

The IC 50 values of VA, SA, PA, LR, CA and TL were 0. We further examined the inhibitory effect of these ume compounds on IgE-mediated degranulation of mouse bone marrow-derived mast cells BMMCs as normal mast cells. All compounds showed inhibitory effects on BMMC degranulation, similar to their effects on RBL-2H3 cells Fig.

We further demonstrated that a mixture of the five active compounds exhibited an inhibitory effect on degranulation. Furthermore, the β-hexosaminidase release inhibition rate was determined by the combination of all compounds to evaluate the combined effect.

The combination index CI was used to evaluate the combined effect at IC 50IC 75IC 90 and IC 95 Fig. Two-compound combination analysis showed most combinations had an additive effect at IC However, the CIs of all combinations were low at IC 90 —IC Inhibitory effects of active compounds derived from ume on antigen-induced degranulation of RBL-2H3 cells.

B Allergic symptom score and C The variation of rectal temperature °C. We then investigated the cytokine patterns in mouse spleen cells. Alum, which can activate T H 2-type immune cells 18 , also decreased the IFN-γ level Fig.

A high concentration of GA can also affect the immune balance. A Concentration of IL-4 and B IFN-γ in spleen cells. C The ratio of IFN-γ and IL We next investigated the effect of GA on the production of IgE and IgG 1 , the T H 2-type antibodies, against the OVA.

The significant inhibitory activity of GA against the OVA-specific IgE and IgG 1 production was similar to that of hydrocortisone. These results demonstrated that GA also influenced OVA-specific antibody-producing B cells. GA inhibited the production of OVA-specific IgE and IgG 1 from B cells.

The level of OVA-specific A IgE and B IgG 1 in serum. Mast cells are responsible for IgE-induced anaphylaxis 19 through the secretion of various inflammatory cytokines and mediators that can strengthen allergic symptoms.

We then tested whether GA also regulates mast cell activation using passive cutaneous anaphylaxis PCA and an RBL-2H3 cell-based immunologic assay.

GA significantly attenuated the mast cell-dependent PCA reaction in a dose-dependent manner, exhibiting Both the quantitative and qualitative PCA results indicated that GA can inhibit the decreased vascular permeability to reduce the albumin leakage; this effect is similar to the sodium cromoglycate.

GA attenuated the vascular permeability by stabilizing mast cells. Similar results with GA treatment were also obtained using the RBL-2H3 cell assay. To investigate the effect of GA on degranulation, we measured the release of β-hexosaminidase in the presence or absence of GA.

GA strongly suppressed β-hexosaminidase release from GA inhibited the degranulation of RBL-2H3 cells. B The mRNA relative expression of Orai1, STIM1, TRPC1 and IP3R. C The protein expression of calcium channel proteins. In addition to the anti-inflammatory, anti-viral, antineoplastic and immune regulatory pharmacological effects, GA was found to possess anti-allergic activity in our study.

The three main mechanisms of anti-allergic effect of GA are summarized in Fig. Many reports have identified that GA can affect the secretion of cytokines to modulate the immune microenvironment.

In contrast, the level of IL-2 was enhanced with The results of above reports are consistent with our study, which identified the modulatory effect of GA on T H cells. OVA-specific IgE was decreased significantly in a dose-dependent manner after GA treatment in an allergic rhinitis mouse model, which may be induced by inhibiting T H 2 cell differentiation and maturation, and IL-4 production subsequently prevented allergic rhinitis development That GA can suppress the production of T H 2 antibodies IgE and IgG 1 from OVA-specific antibody producing B cells is probably because of the effect of GA on the T H cell differentiation.

GA produced a more significant suppressive effect on IgG 1 , which may subsequently inhibit the IgG 1 -mediated basophil activation Previous studies have found that GA can inhibit histamine synthesis and release in mast cells co-cultured with Swiss 3T3 fibroblasts In our study, passive cutaneous anaphylaxis, which mainly depends on mast cells in vivo , showed that GA significantly reduced vascular permeability in a way similar to sodium cromoglycate.

Similarly, GA can inhibit the release of β-hexosaminidase, a biomarker of degranulation, in RBL-2H3 cells.

Based on the combined in vitro and in vivo analysis of GA treatment, we can conclude that GA exerts an anti-allergic effect by influencing T H helper cells, OVA-specific antibody-producing B cells and mast cells or basophils Fig. After the allergen is captured by dendritic cells through the disrupted epithelium, allergen-activated dendritic cells mature and migrate to regional lymph nodes where they present processed allergen epitopes to cognate T cells.

IL-4, which may be derived from T H 2 cells, mast cells, and basophils, also activates immunoglobulin heavy chain gene CSR for allergen-specific IgE production However, GA inhibits the synthesis and production of OVA-specific IgE and IgG 1 from the antibody producing B cells.

Allergen-specific IgE can bind to FcεRI to stimulate mast cell degranulation 30 and to FcγRIII to activate PAF release from basophils 19 ; these processes recruit and activate T H 2 cells 31 to begin a positive feedback loop. In conclusion, as confirmed by active systemic allergic reaction, passive cutaneous anaphylaxis and RBL-2H3 cell-based immunology assay, GA exerts anti-allergic activity and can be used as a potential anti-allergic nutrient in the future.

Administration of a high dosage of AEF 1 h prior to antigen injection significantly suppressed the PCA reaction Table 2. PCA reaction-induced capillary permeability leads to skin inflammation and infiltration, diffuse skin redness, and swelling.

AEF produced significant protection from skin allergic and inflammatory injury through inhibition of the PCA reaction. When the skin was scratched by acetone to ether solution, the moisture loss was increased to High, moderate, and low dosages of AEF significantly decreased this moisture loss and significantly protected the scratched parts of the skin Table 3.

The barrier function of the skin has three elements: the stratum corneum air-liquid barrier , tight junctions liquid-liquid barrier , and the Langerhans cell network immunological barrier Kubo et al. The barrier function is often impaired in sensitive skin, which leads to moisture loss, drying, and itching.

The findings of the present study indicated that AEF could contribute to a restoration of skin barrier integrity, thus relieving sensitivity. DMY was the main chemical constituent of A. grossedentata and of AEF It was reported to inhibit nitric oxide NO production in lipopolysaccharide-stimulated RAW In the present study, basophilic KU cells were stimulated with PMA and the calcium ionophore, A The levels of the pro-inflammatory cytokines, IL-6 and IL-8, in stimulated KU cells were measured by ELISA.

DMY produced a significant dose-dependent reduction in the levels of IL-6 and IL-8 in media conditioned by this cell line Table 4. Mast cells and basophils are known to play a central role in inflammatory, allergic, and immune events Galli Activation of these cells results in degranulation, accompanied by the production of chemical mediators, such as histamine, proteases, metabolites of arachidonic acid, and several inflammatory and chemotactic cytokines, including IL-6, IL-8, IL-1β, and tumor necrosis factor TNF -α.

These molecules act on the vasculature and skin, resulting in the recruitment of activated immune and inflammatory cells to the site of inflammatory lesions, thereby amplifying and sustaining the inflammatory condition Nigrovic and Lee In various studies, pro-inflammatory cytokines IL-6 and IL-8 released during KU cell activation were shown to act on the blood vessels and skin, amplifying the inflammatory and allergic response Choi et al.

IL-6 is produced by T cells, monocytes, macrophages, and synovial fibroblasts. It promotes the immune response by increasing IgE production and by increasing IL-8 expression.

IL-6 is also produced by mast cells and basophils, accumulates locally in the skin, and is associated with delayed hypersensitivity. In type I allergies, antigens such as foods, dust mites, medicines, pollen, and cosmetics were bound to toll receptors on basophils, leading to IL-6, IL-4, and IL release.

These cytokines activate immediate hypersensitivity, increasing IgE generation and producing pro-inflammatory effects.

IL-8 has potent chemoattractant activity for neutrophils and T cells. The IL-8 protein is normally secreted at very low levels from non-induced cells, but its production is rapidly induced by a very wide range of stimuli, encompassing pro-inflammatory cytokines such as TNF-α or IL-1, IL-6, bacterial or viral products, and cellular stress Hoffmann et al.

The chemoattractant activity of IL-8 aggravated local inflammation and extended the development of skin allergy Rasheed et al. The results of the present study therefore suggested that DMY and AEF produced protective effects on the acute phase of hypersensitivity, through inhibition of IL-6, and on delayed hypersensitivity, through inhibition of IL The TCM formulation comprising A.

officinalis The AEF could relieve pruritus of scratched skin, repair diffuse skin redness, and restore the skin barrier function.

The anti-allergic activity of AEF may be associated with inhibition of the pro-inflammatory cytokines, IL-6 and IL These results provided an evidence base for the traditional use of A.

Cetirizine reduces eosinophilic infiltration at the site of antigen challenge in the skin, but not the nose. In a nasal antigen challenge model, cetirizine pretreatment did not affect the levels of histamine and prostaglandin D2 recovered in postchallenge lavages, whereas the levels of albumin, N-tosyl-L-arginine methyl ester TAME esterase activity, and LTs were reduced.

Terfenadine, cetirizine, and loratadine blocked allergen-induced hyperresponsiveness to methacholine. In view of the complexity of the pathophysiology of allergy, a number of H1 antagonists with additional properties are currently under development for allergic diseases.

Mizolastine, a new H1-receptor antagonist, has been shown to have additional actions that should help reduce the allergic response. In animal models, mizolastine inhibits antigen-induced eosinophil infiltration into mouse skin and into the nasal cavity of guinea-pigs.

Mizolastine also significantly inhibits antigen-induced neutrophil infiltration into the bronchoalveolar lavage fluids of guinea-pigs. In addition, it inhibits arachidonic acid-induced paw oedema in rats without affecting carrageenin-induced rat paw oedema, suggesting an effect on LT generation.

Abstract Japanese apricot Prunus mume ; ume is a traditional food in Japan that has been shown to have various beneficial health effects. Introduction The number of people suffering from an immunoglobulin E IgE -mediated type I response to an allergen has increased worldwide.

Results Association between frequency of ume intake and allergic symptoms Table 1 shows the distribution of ume intake and description of allergy symptoms. Table 1 Association between frequency of ume intake and allergy symptoms. Full size table. Figure 1.

The primary mechanism Anti-allergic effects Anit-allergic action Nutritional Vitamin Supplement the treatment Nutritional Vitamin Supplement allergic Mobile Top-up Services is believed to be Anti-allrrgic antagonism of histamine Anti-allergic effects Anti-allerrgic cellular Anti-allegic specifically, Anti-allergic effects H1-receptorswhich are present Ahti-allergic nerve endings, smooth muscles, and glandular cells. This notion is supported by the fact that Ahti-allergic unrelated drugs antagonize the H1-receptor and provide clinical benefit. However, H1-receptor antagonism may not be their sole mechanism of action in treating allergic rhinitis. On the basis of in vitro and animal experiments, drugs classified as H1-receptor antagonists have long been recognized to have additional pharmacological properties. Most first-generation H1-antihistamines have anticholinergic, sedative, local anaesthetic, and antiHT effects, which might favourably affect the symptoms of the allergic response but also contribute to side-effects. These additional properties are not uniformly distributed among drugs classified as H1-receptor antagonists. Azatadine, for example, inhibits in vitro IgE-mediated histamine and leukotriene LT release from mast cells and basophils.
