Abstract
African swine fever (ASF) has become a global pandemic due to inadequate prevention and control measures, posing a significant threat to the swine industry. Despite the approval of a single vaccine in Vietnam, no antiviral drugs against the ASF virus (ASFV) are currently available. Aloperine (ALO), a quinolizidine alkaloid extracted from the seeds and leaves of bitter beans, exhibits various biological functions, including anti-inflammatory, anti-cancer, and antiviral activities. In this study, we found that ALO could inhibit ASFV replication in MA-104, PK-15, 3D4/21, and WSL cells in a dose-dependent manner without cytotoxicity at 100 μM. Furthermore, it was verified that ALO acted on the co- and post-infection stages of ASFV by time-of-addition assay, and inhibited viral internalization rather than directly inactivating the virus. Notably, RT-qPCR analysis indicated that ALO did not exert anti-inflammatory activity during ASFV infection. Additionally, gene ontology (GO) and KEGG pathway enrichment analyses of transcriptomic data revealed that ALO could inhibit ASFV replication via the PRLR/JAK2 signaling pathway. Together, these findings suggest that ALO effectively inhibits ASFV replication in vitro and provides a potential new target for developing anti-ASFV drugs.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 313:116613. [PMID: 37156447 DOI: 10.1016/j.jep.2023.116613] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/03/2023] [Accepted: 05/05/2023] [Indexed: 05/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Probiotic fermentation is a mild and safe biological method to boost the performance of herbs. Portulaca oleracea L. (PO), with folklore records of purgative, anti-dermatological and anti-epidemic effects, has been demonstrated to possess anti-inflammatory, immunomodulatory, and antioxidant properties. However, the potential of PO for the treatment of atopic dermatitis (AD) has not been sufficiently explored. AIM OF STUDY This study aimed to evaluate the therapeutic benefits of PO and fermented Portulaca oleracea L. (FPO) and explore their intrinsic mechanisms. METHODS By utilizing 2,4-dinitrofluorobenzene-induced AD mice as a model, the histopathology of the lesions was observed using H&E and toluidine blue staining methods; the levels of immunoglobulin E (Ig E), histamine (HIS), and thymic stromal lymphopoietin (TSLP) in serum were measured using ELISA, whereas, the expression of inflammatory cytokines in skin lesion was measured using ELISA and immunohistochemistry experiments. The expression of tumor necrosis factor-α (TNF-α), IKKα, NF-κB mRNA was measured using qPCR; and the expression of TNF-α、p-IKKα, p-IκBα, p-NF-κB was measured using western blotting. RESULTS Both 20 mg/mL PO and FPO alleviated mast cell infiltration and lesion pathology, reduced serum levels of Ig E, HIS and TSLP, down-regulated the expression of AD-related inflammatory cytokines, such as, TNF-α, interferon-γ, and interleukin-4, and increased filaggrin expression. Furthermore, they inhibited the expression of TNF-α, IKKα, and NF-κB genes and TNF-α, p-IKKα, p-NF-κB and p-IκBα proteins associated with the NF-κB signaling pathway. CONCLUSIONS PO and FPO has a positive therapeutic potential on AD, indicating that it may be employed as alternative therapies for AD.

Abstract
COVID-19, caused by the highly transmissible severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has rapidly spread and become a pandemic since its outbreak in 2019. We have previously discovered that aloperine is a new privileged scaffold that can be modified to become a specific antiviral compound with markedly improved potency against different viruses, such as the influenza virus. In this study, we have identified a collection of aloperine derivatives that can inhibit the entry of SARS-CoV-2 into host cells. Compound 5 is the most potent tested aloperine derivative that inhibited the entry of SARS-CoV-2 (D614G variant) spike protein-pseudotyped virus with an IC50 of 0.5 µM. The compound was also active against several other SARS-CoV-2 variants including Delta and Omicron. Results of a confocal microscopy study suggest that compound 5 inhibited the viral entry before fusion to the cell or endosomal membrane. The results are consistent with the notion that aloperine is a privileged scaffold that can be used to develop potent anti-SARS-CoV-2 entry inhibitors.

Abstract
Cold atmospheric plasma has been widely applied in medical treatment clinically, especially skin diseases. However, the mechanism of cold atmospheric plasma on the treatment of skin diseases is still undefined. In this study, dinitrofluorobenzene-induced atopic dermatitis mice model was constructed. Cold atmospheric plasma was able to decrease skin cells apoptosis, relieve skin inflammation, ER stress and oxidative stress caused by dinitrofluorobenzene stimulation, which was mediated by cold atmospheric plasma-induced MANF expression. In terms of mechanism, hypoxia-inducible factor-1α expression was increased intracellularly after cold atmospheric plasma treatment, which further bound to the promoter region of manf gene and enhanced MANF transcriptional expression. This study reveals that cold atmospheric plasma has a positive effect on atopic dermatitis treatment, also demonstrates the regulatory mechanism of cold atmospheric plasma on MANF expression via HIF-1α, which indicates the potential medical application of cold atmospheric plasma for atopic dermatitis treatment.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory allergic skin disease, characterized by pruritic and eczematous skin lesions. Lycopus lucidus Turcz (LLT) is a perennial herb that has been reported to have various biological properties, including effects on blood circulation, as well as anti-inflammatory, antioxidant, anti-vascular inflammation and wound-healing effects. However, whether LLT improves dermatitis and the underlying mechanisms has yet to be determined. The aim of the present study was to determine whether LLT can improve 2,4-dinitrochlorobenzene (DNCB)-induced dermatitis and to verify the inhibitory effect of LLT on the expression of chemokines and pro-inflammatory cytokines in the HaCaT immortalized keratinocyte cell line. In addition, the anti-inflammatory function of LLT in RAW264.7 mouse macrophages was investigated. In the DNCB-induced AD mouse model, LLT inhibited infiltration by mast cells, eosinophils and CD8+ cells in the dorsal skin tissue of AD mice, and suppressed the expression of IgE and IL-6 in serum. In addition, LLT inhibited the phosphorylation of ERK and JNK, as well as NF-κB in skin tissue. In the HaCaT cell model induced by TNF-α/IFN-γ, LLT inhibited the expression of thymus and activation-regulated chemokine, granulocyte-macrophage colony-stimulating factor, monocyte chemoattractant protein-1, TNF-α and IL-1β, whilst inhibiting the phosphorylation of NF-κB. In addition, in the lipopolysaccharide-induced RAW 264.7 cell inflammation model, LLT inhibited the expression of TNF-α and IFN-γ, the nuclear translocation of NF-κB and the phosphorylation of ERK and JNK. These results suggested that LLT may be a promising candidate for the treatment of inflammatory dermatitis.

Abstract
Aloperine, a quinolizidine-type alkaloid, was first isolated from the seeds and leaves of herbal plant, Sophora alopecuroides L. Empirically, Sophora alopecuroides L. is appreciated for its anti-dysentry effect, a property that is commonly observed in other Sophora Genus phytomedicines. Following the rationale of reductionism, subsequent biochemical analyses attribute such anti-dysentry effect to the bactericidal activity of aloperine. From then on, the multiple roles of aloperine are gradually revealed. Accumulating evidence suggests that aloperine possesses multiple pharmacological activities and holds a promising potential in clinical conditions including skin hyper-sensitivity, tumor and inflammatory disorders etc.; however, the current knowledge on aloperine is interspersed and needs to be summarized. To facilitate further investigation, herein, we conclude the key pharmacological functions of aloperine, and most importantly, the underlying cellular and molecular mechanisms are clarified in detail to explain the functional mode of aloperine.

A key role for IL-13 signaling via the type 2 IL-4 receptor in experimental atopic dermatitis. Sci Immunol 2020; 5:5/44/eaaw2938.

Abstract
IL-13 and IL-4 are potent mediators of type 2-associated inflammation such as those found in atopic dermatitis (AD). IL-4 shares overlapping biological functions with IL-13, a finding that is mainly explained by their ability to signal via the type 2 IL-4 receptor (R), which is composed of IL-4Rα in association with IL-13Rα1. Nonetheless, the role of the type 2 IL-4R in AD remains to be clearly defined. Induction of two distinct models of experimental AD in Il13ra1 -/- mice, which lack the type 2 IL-4R, revealed that dermatitis, including ear and epidermal thickening, was dependent on type 2 IL-4R signaling. Expression of TNF-α was dependent on the type 2 IL-4R, whereas induction of IL-4, IgE, CCL24, and skin eosinophilia was dependent on the type 1 IL-4R. Neutralization of IL-4, IL-13, and TNF-α as well as studies in bone marrow-chimeric mice revealed that dermatitis, TNF-α, CXCL1, and CCL11 expression were exclusively mediated by IL-13 signaling via the type 2 IL-4R expressed by nonhematopoietic cells. Conversely, induction of IL-4, CCL24, and eosinophilia was dependent on IL-4 signaling via the type 1 IL-4R expressed by hematopoietic cells. Last, we pharmacologically targeted IL-13Rα1 and established a proof of concept for therapeutic targeting of this pathway in AD. Our data provide mechanistic insight into the differential roles of IL-4, IL-13, and their receptor components in allergic skin and highlight type 2 IL-4R as a potential therapeutic target in AD and other allergic diseases such as asthma and eosinophilic esophagitis.

Pediococcus acidilactici intake decreases the clinical severity of atopic dermatitis along with increasing mucin production and improving the gut microbiome in Nc/Nga mice. Biomed Pharmacother 2020; 129:110488. [PMID: 32768968 DOI: 10.1016/j.biopha.2020.110488] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Revised: 06/18/2020] [Accepted: 06/30/2020] [Indexed: 12/11/2022] Open
Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease that is associated with intestinal microflora. Since specific probiotics may have better efficacy for AD, we determined the efficacy of Pediococcus acidilactici SRCM102024 (PA) for treating AD in HaCaT cells and NC/Nga mice and explored the mechanism of action. AD-like pathology was induced in HaCaT cells and the dorsal skin of Nc/Nga mice by local exposure to 2,4-dinitrochlorobenzene (DNCB). In AD-lesion induced mice, PA in low-, medium- and high-dosages (5 × 10E6, 5 × 10E7 and 5 × 10E8 CFU/kg bw, respectively) and dexamethasone (3 mg/kg bw, positive-control) were orally administered for 5 weeks. The clinical AD severity, serum immunoglobulin E (IgE) and TNF-α, gene expressions of interleukin (IL)-4, IL-13, and TNF-α and gut microflora were measured. PA treatment (100-300 CFU/mL) dose-dependently increased cell survival in DNCB-induced HACAT cells. PA reduced the relative mRNA expression of PAR-2, TNF-α, IL-4 and IL-13 in the cells. In dorsal skin of Nc/Nga mice applied with DNCB, PA dose-dependently attenuated erythema, hemorrhage, edema, excoriation, dryness and scratching behavior and PA-H improved the clinical symptoms similar to the positive-control. PA-M and PA-H treatment significantly prevented the disturbance of the dorsal skin tissues and decreased the inflammatory cellular infiltrate of mast cells, compared to the control. PA dose-dependently reduced serum IgE and TNF-α concentrations and the mRNA expression of TNF-α, IL-4, and IL-13 in dorsal skin. In gut microflora, relative counts of Lactobacillales, Butyricicoccus and Ruminococcus were decreased in the AD-control compared to the positive-control and the PA-M and PA-H prevented their decrease. However, the positive-control increased serum AST and ALT activities, indicating liver damage as an adverse effect. In conclusion, oral treatment of PA (human equivalent 1 × 10E9-1 × 10E10) relieved the AD symptoms by dose-dependently preventing over-activation of the immune response. Oral PA intake may be a safe and effective alternative therapy for AD.

Abstract
Seaweed fulvescens (SF) is a green alga rich in chlorophyll with unique flavor and taste. It is also called Maesaengi which has antioxidant and other physiological activities. In the present study, we evaluated the therapeutic effects of SF in a mouse model of Dermatophagoides farinae body-induced atopic dermatitis (AD) and in tumor necrosis factor-α and interferon-γ-stimulated HaCaT keratinocytes. SF treatment (200 mg/mouse) inhibited the development of AD symptoms, compared to that in the control group, as evidenced from the improved dorsal skin lesion, reduced thickness and infiltration of inflammatory cells and smaller lymph nodes, and reduced levels of proinflammatory cytokines. In HaCaT keratinocytes, SF (10, 25, and 50 μg/mL) suppressed the production of proinflammatory cytokines in a dose-dependent manner. In addition, SF reduced the phosphorylation of signal transducer and activator of transcription 1, which is one of the major signaling molecules involved in cellular inflammation. These results suggested that SF could be a potential therapeutic alternative for the treatment of AD.

Abstract
Aloperine is a quinolizidine alkaloid extracted from Sophora alopecuroides. It has been proven to alleviate oxidative stress and effectively promote tumor cell apoptosis in mice. Herein, we investigated whether aloperine could also mediate its protective effects on bleomycin (BLM)-induced pulmonary fibrosis. Pathological staining, western blot, RT-PCR and flow cytometry were used to evaluate the impact of aloperine on the development of pulmonary fibrosis. The effect of aloperine on fibroblast proliferation, differentiation and related signaling pathways were next investigated to demonstrate the underlying mechanisms. In the present report, we showed that aloperine provided protection for mice against BLM-induced pulmonary fibrosis as manifested by the attenuated lung injury and reduced fibrosis along with alleviated fibroblast proliferation and differentiation. Additionally, we provided in vitro evidence revealing that aloperine inhibited cellular proliferation in PDGF-BB-stimulated mouse lung fibroblasts by repressed PI3K/AKT/mTOR signaling and fibroblast to myofibroblast differentiation by repressed TGF-β/Smad signaling. Overall, our data showed that aloperine could protect the mice against BLM-induced pulmonary fibrosis by attenuated fibroblast proliferation and differentiation, which indicated that aloperine may be therapeutically beneficial for IPF patients.

Abstract
INTRODUCTION A major clinical challenge in treating allergic contact dermatitis (ACD) is that the first line of treatment is based on the use of corticosteroids. In this study, we aimed to develop a formulation that is devoid of steroids. METHODS We used mouse ears treated with dinitrofluorobenzene (DNFB) to induce ACD. The efficacy of the test formulation to ameliorate and to prevent induced ACD was determined. RESULTS To treat this experimentally induced ACD, we developed a formulation containing BIPxine (a mixture of Rosa moschata and Croton lechleri (antioxidants) and Aloe vera and D-panthenol (moisturizers), and hydroglycolic solutions of disodium cromoglycate. Our results show that clear inhibition of ACD took place. The target of this formulation was PAR-2, TRPV4, and other mediators of the inflammatory and pain responses. However, this formulation must be evaluated in other models besides the mouse to confirm its effectiveness. CONCLUSION The formulation presented here may provide new ACD therapies that do not involve the use of corticosteroids.

Abstract
Colitis is a major form of inflammatory bowel disease which involved mucosal immune dysfunction. Aloperine is an alkaloid isolated from the shrub Sophora alopecuroides L. and has been recognized as an effective treatment for inflammatory and allergic diseases. The present study aimed to examine the molecular mechanisms underlying aloperine-mediated colitis protection. We found that aloperine treatment improved colitis induced by dextran sodium sulfate (DSS) based on body weight, disease activity index, colonic length, and spleen index. Aloperine also effectively attenuated DSS-induced intestinal inflammation based on the pathological score and myeloperoxidase expression and activity in colon tissues. In addition, aloperine regulated T-cell proportions and promoted Foxp3 expression in the spleens and mesenteric lymph nodes of DSS-induced colitis mice and in the spleens of the Foxp3GFP mice. Aloperine inhibited Jurkat and mouse naïve T-cell apoptosis. Furthermore, aloperine inhibited PI3K/Akt/mTOR signaling and upregulated PP2A expression in the DSS-induced colitis mice and in Jurkat cells, but LB-100 (PP2A inhibitor) resulted in an elevated Akt activity in Jurkat cells, activated T-cells, and human splenic mononuclear cells. Aloperine inhibited T-cell and lymphocyte proliferation, but LB-100 reverse these effects. In conclusion, aloperine regulates inflammatory responses in colitis by inhibiting the PI3K/Akt/mTOR signaling in a PP2A-dependent manner.

Abstract
Allergic contact dermatitis is a common skin disease and the current treatment always along with frequent medication and side effect. In this research, poly(d,l-lactide- co-glycolide) microspheres encapsulating tacrolimus are first employed as a therapy of allergic contact dermatitis in mice model by subcutaneous injection. Allergic contact dermatitis is successfully induced in BALB/c mice by repeated painting of dinitrofluorobenzene on mice ear. Tacrolimus is efficiently encapsulated into poly(d,l-lactide- co-glycolide) microspheres by emulsion evaporation method, and then the microspheres are subcutaneously injected into dermatitis-suffered BALB/c mice. We find that the dermatitis mice treated with tacrolimus-loaded microspheres get a sustained suppression on ear swelling, dermatitis index, inflammatory cell accumulation, and serum immunoglobulin E concentration. The curative effect of tacrolimus-loaded microspheres is similar to daily tacrolimus injection and is even better in the inhibition of ear swelling. Dermatitis mice treated with blank microspheres get no curative effect during the whole experiment. The data suggest that subcutaneous injection of drug-loaded microspheres could be a potential candidate for the management of allergic contact dermatitis.

Abstract
Aloperine is an alkaloid that exerts significant inhibitive effects on acute inflammation and Type III and IV hypersensitivity caused by a variety of inflammatory agents. The aims of the present study were to investigate whether the protective effect of aloperine attenuates hydrogen peroxide (H2O2)-induced injury, and to identify the underlying mechanisms involved. Nucleus pulposus cells were extracted from adult male Sprague-Dawley rats, and incubated with fresh medium containing 200 µM H2O2 for 24 h. In the study, treatment with aloperine significantly increased cell viability and suppressed apoptosis in H2O2-treated nucleus pulposus cells in a dose-dependent manner. In addition, 10 and 100 nM aloperine significantly inhibited H2O2-induced tumor necrosis factor-α and interleukin-6 activities, and significantly increased the H2O2-reduced superoxide dismutase and glutathione peroxidase activities in nucleus pulposus cells (all P<0.01). However, aloperine treatment (10 and 100 nM) significantly reduced the H2O2-induced caspase-9 activity in nucleus pulposus cells. Furthermore, addition of 10 and 100 nM aloperine significantly suppressed nuclear factor-κB (NF-κB) and phosphorylated-protein kinase B expression levels in H2O2-treated nucleus pulposus cells. In conclusion, the protective effect of aloperine attenuated H2O2-induced injury via hyperproliferation, its anti-apoptotic activity and suppression of the NF-κB signaling pathway.

Abstract
The present study investigated the effect of Sargassum fulvellum ethanol extract (SFEE) on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD)-like skin lesions in BALB/c mice. The severity of skin dermatitis, production of cytokines, and total IgE content were measured, and the histopathological features were analyzed. SFEE decreased the severity of DNCB-induced dermatitis and suppressed the serum levels of total immunoglobulin E (IgE), tumor necrosis factor (TNF)-α, and interleukin (IL)-4. In addition, SFEE reduced the production of IL-4, IL-5, and IL-13 in mice splenocytes. However, the levels of IL-10 and interferon (IFN)-γ significantly increased in mice sera and splenocytes. Histological examination revealed decreased dermal thickness and infiltration by mast cells after treatment with SFEE. Furthermore, grasshopper ketone, a compound isolated from SFEE, was found to significantly decrease cytokine production in concanavalin A-stimulated splenocytes from BALB/c mice with no cytotoxicity. Taken together, these results indicate that SFEE and the isolated grasshopper ketone have an inhibitory effect on AD by regulating immune mediators and cells and may be a potential effective alternative therapy for AD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Chinese herb compound prescription Viola yedoensis Makino Anti-itching Compound (VYAC), which consists of Viola yedoensis Makino, herb, Sophora flavescens Aiton, root, and Dictamnus dasycarpus Turcz, root and rhizome, has been traditionally used to treat various skin allergic inflammatory diseases in clinic. AIM OF THE STUDY The aim of this study is to investigate the effects of VYAC on degranulation and to determine its anti-inflammatory mechanism in RBL-2H3 mast cells. MATERIALS AND METHODS VYAC was extracted with water-coction extraction (Shufen et al., 2012). The aqueous extracts were concentrated in vacuum under reduced pressure and lyophilized using a freeze dryer, and lyophilized powder was obtained. MTT was used to evaluate the cytotoxic of VYAC on RBL-2H3 cells. Degranulation was carried out with RBL-2H3 cell model, which was stimulated with A23187 plus PMA. β-Hexosaminidase and histamine were measured to evaluate degranulation. The mRNA levels of inflammation cytokines (IL-1β, TNF-α, IL-6, and iNOS) were investigated by RT-PCR to explain the anti-inflammatory mechanism of VYAC. RESULTS VYAC did not show cytotoxic effect on RBL-2H3 cells in the range of 25-400μg/mL. A higher dose of VYAC (800μg/mL) showed significant cytotoxicity (P<0.05). VYAC could significantly inhibit β-hexosaminidase and histamine release when treated with 100, 200, and 400μg/mL (P<0.05), but could not significantly inhibit β-Hexosaminidase and histamine release when treated with 25 and 50μg/mL (p>0.05). The mRNA levels of inflammatory cytokines (TNF-α, IL-1β, IL-6, and iNOS) could significantly decrease when treated with 200 and 400μg/mL (P<0.05) of VYAC, which were associated with the development of inflammation. CONCLUSIONS Results showed that VYAC inhibited β-hexosaminidase and histamine release, which was inhibit A23187 plus PMA stimulated RBL-2H3 cell degranulation and downregulated inflammatory cytokines (IL-1β, TNF-α, IL-6, and iNOS) expression to block inflammatory development.

Abstract
Cymbidium has known antibacterial and antiedema activity and has been used as an ingredient in cosmetics and fragrances. The effects of Cymbidium ethanol extract (CYM) on allergic response and the underlying mechanisms of action have not been reported. Therefore, the purpose of this study was to determine the effect of CYM on allergic responses. Topical application of CYM was effective against immunoglobulin E (IgE)/dinitrophenyl-conjugated bovine serum albumin- (DNP-BSA-) induced degranulation of RBL-2H3 cells and anaphylaxis in ICR mice. An allergic dermatitis-like mouse model was used to evaluate the therapeutic potential of CYM in vivo. Continuous application of 2,4-dinitrochlorobenzene (DNCB) not only induced dermatitis in ICR mice but also aggravated the skin lesioning. However, the application of CYM decreased skin lesion severity, scratching behavior, and IgE levels. In addition, CYM downregulated the expression of the proinflammatory cytokines interleukin- (IL-) 4, IL-13, and tumor necrosis factor- (TNF-) α. Studies of signal transduction pathways showed that CYM suppressed the phosphorylation of spleen tyrosine kinase (Syk), an upstream molecule. It also inhibited the phosphorylation of Akt, phospholipase C- (PLC-) γ, and mitogen-activated protein kinase kinase kinase (MEKK). These results indicate that CYM may be effective in preventing and reducing allergic response and may have therapeutic potential as an antiallergic agent in disorders such as atopic dermatitis.

Abstract
Atopic dermatitis (AD) is among the most common skin disorders in humans. Although a variety of regimens are available for the treatment of AD, preventive approaches are limited. Recent studies have demonstrated that certain naturally-occurring herbal medicines are effective in preventing the development of AD via divergent mechanisms, such as inhibiting cytokine and chemokine expression, IgE production, inflammatory cell infiltration, histamine release, and/or enhancement of epidermal permeability barrier function. Yet, they exhibit few adverse effects. Since herbal medicines are widely available, inexpensive and generally safe, they could represent an ideal approach for preventing the development of AD, in both highly developed and developing countries.

Abstract
Solanum tuberosum L. cv Jayoung (JY) is a potato with dark purple flesh and contains substantial amounts of polyphenols. In this study, we evaluated the therapeutic effects of S. tuberosum L. cv JY in a mouse model of Dermatophagoides farinae body (Dfb)-induced atopic dermatitis (AD). The ethanol extract of the peel of JY (EPJ) ameliorated Dfb-induced dermatitis severity, serum levels of immunoglobulin E (IgE) and thymus and activation-regulated chemokine. Histological analysis of the skin also revealed that EPJ treatment significantly decreased mast cell infiltration. The suppression of dermatitis by EPJ treatment was accompanied by a decrease in the skin levels of type 2 helper T-cell cytokines such as interleukin (IL)-4, IL-5, and IL-13. The induction of thymic stromal lymphopoietin, which leads to a systemic Th2 response, was also decreased in the skin by EPJ. Nuclear translocation of nuclear factor-κB p65 was decreased by EPJ in Dfb-induced NC/Nga mice. The protein expression of filaggrin in the AD-like skin lesions was restored by EPJ treatment. These results suggested that EPJ may be a potential therapeutic tool for the treatment of AD.

Abstract
(S)-(+)-decursin is a biological coumarin compound isolated from Angelica gigas Nakai. (S)-(+)-decursin and its analogue have a variety of pharmacological activities. In the present study, the anti-inflammatory effect of a (S)-(+)-decursin derivative, (S)-(+)-3-(3,4-dihydroxy-phenyl)-acrylic acid 2,2-dimethyl-8-oxo-3,4-dihydro-2H,8H-pyrano [3,2-g]-chromen-3-yl-ester (Compound 6, C6), on in vitro and in vivo atopic dermatitis was investigated. C6 suppressed the secretion of IL-6, IL-8, and monocyte chemotactic protein-1 increase by the house dust mite extract in the eosinophilic leukemia cell line and THP-1 cells. C6 inhibited the production of TARC, IL-6, and IL-8 increase by IFN-γ and TNF-α in the human keratinocyte cell line. In the in vivo experiment, NC/Nga mice were sensitized to 2,4-dinitrochlorobenzene, and then C6 or dexamethasone (Dex) were orally and dorsally administered for three weeks. C6 treatment reduced the skin severity score compared with that of the control group. C6 inhibited the thickening of the epidermis and inflammatory cell infiltration into the dermis by evaluating the histological examination. The serum immunoglobulin E (IgE) level decreased in the C6-treated group compared with that of the control group. The inhibitory effect of C6 on IgE concentration was similar to that of Dex. The levels of IL-4, IL-5, IL-13, and eotaxin increased after treatment with concanavalin A in mouse splenocytes. The cytokine levels of the C6-treated group were lower than those of the control group. Taken together, C6 may attenuate atopic dermatitis-like lesions through its anti-inflammatory effect, such as inhibition of IgE and inflammatory cytokines, and it may be valuable as a therapeutic drug for the treatment of atopic dermatitis.

Int Immunopharmacol 2012; 14:384-91.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease for which few effective treatments are available. Resolvin E1 (RvE1; 5S,12R,18R-trihydroxy-6Z,8E,10E,14Z,16E-eicosapentaenoic acid) is an endogenous lipid mediator derived from omega-3 fatty eicosapentaenoic acid, which is a potent inhibitor of inflammation. AD-like skin lesion was induced by repetitive skin contact with DNFB in NC/Nga mice and the effects of RvE1 were evaluated on the basis of histopathological findings of skin, ear swelling and cytokine production of CD4(+) T cells. Intraperitoneal injection of RvE1 for one week after DNFB challenge significantly lowered ear swelling and improved back skin lesions. In addition, RvE1 significantly suppressed production of interferon-gamma (IFN-γ) and interleukin-4 (IL-4) by activated CD4(+) T cells and serum IgE level. Furthermore, RvE1 reduced DNFB-induced infiltration of eosinophils, mast cells, CD4(+) T cells, and CD8(+) T cells in skin lesions. Therefore, RvE1 may suppress the development of AD-like skin lesions in DNFB-treated NC/Nga mice by reducing IL-4 and IFN-γ of activated CD4(+) T cells and serum IgE levels and infiltration of immune cells to skin lesion.

Abstract
Various factors have been reported to influence lipid metabolism and cause metabolic syndrome. However, the influence of allergy on the liver that plays important role of lipid metabolism has not been clarified. The aim of this study was to examine the influence of allergy on lipid metabolism of liver. A model of atopic dermatitis was developed in the NC/Nga mouse using picryl chloride to induce allergy. Lipid metabolism parameters were measured and the mechanism of changes in these parameters was examined using DNA microarray analysis and quantitative reverse transcriptase PCR. Triacylglycerol accumulation was promoted in the liver in the mouse atopic dermatitis model despite reductions in food intake, body weight gain, and serum glucose. As this mechanism, it was thought that atopic dermatitis caused the suppression of fatty acid β-oxidation. These results suggest that atopic dermatitis causes lipid accumulation in the liver.
