Abstract
In this study, we evaluated the effect of oral administration of galacto-oligosaccharide (GOS), famous biological molecules that are comprised of galactose and lactose, on ovalbumin (OVA)-induced allergic dermatitis. OVA-induced mice were divided into the OVA-administered group (OVA-C), promethazine hydrochloride-administered group (PC), and 100 and 200 mg kg-1 GOS-administered groups (GL and GH, respectively). GOS administration significantly improved epidermal thickness and decreased CD4+ cell numbers. The concentrations of IgE, OVA-specific IgE, and inflammatory cytokines (IL-4, IL-5, and INF-γ) in GH group mice were significantly lower than those in OVA-C group mice. Firmicutes and Bacteroidetes were identified as the major phyla in the intestinal microbiota in mice, and the relative abundance of Deferribacteres was significantly lower in the GH group than in the OVA-C group. Deferribacteraceae and Mucispirillum species were significantly lower in the GH group than in the OVA-C group. The relative abundance of Muribaculum species was significantly lower, but those of Lachnospira and Lactococcus species were significantly higher in the GH group than in the OVA-C group. Our results suggest that the alleviation effect of GOS on allergic dermatitis induced by OVA sensitization was achieved by regulating hypersensitive immune responses by improving the intestinal microbial ecosystem.

Abstract
BACKGROUND Atopic dermatitis (AD) is characterized by intense pruritis and is a common childhood inflammatory disease. Many factors are known to affect AD development, including the pleiotropic cytokine IL-4. Yet little is known regarding the direct effects of IL-4 on keratinocyte function. OBJECTIVE AND METHODS In this report RNA sequencing and functional assays were used to define the effect of the allergic environment on primary keratinocyte function and wound repair in mice. RESULTS Acute or chronic stimulation by IL-4 modified expression of more than 1000 genes expressed in human keratinocytes that are involved in a broad spectrum of nonoverlapping functions. Among the IL-4-induced changes, repression of fibronectin critically impaired the human keratinocyte wound response. Moreover, in mouse models of spontaneous and induced AD-like lesions, there was delayed re-epithelialization. Importantly, topical treatment with fibronectin restored the epidermal repair response. CONCLUSION Keratinocyte gene expression is critically shaped by IL-4, altering cell fate decisions, which are likely important for the clinical manifestations and pathology of allergic skin disease.

Abstract
Nodakenin, derived from the roots of Angelica gigas Nakai, is an important natural resource and medicinal material with anti-allergic and anti- inflammatory activities. We have previously shown that nodakenin inhibits IgE/Ag-induced degranulation in mast cells. In this study, we investigated the inhibitory effect of nodakenin on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD)- like skin lesions in ICR mice. Scratching behavior, skin severity score, blood IgE level, and skin thickness were improved in DNCB-induced AD-like ICR mice. Our results showed that nodakenin suppressed the increase of AD-like skin lesions in ICR mice. These results suggest that nodakenin may be a potential therapeutic resource for AD as well as an adjunctive agent to control itching associated with AD.

Abstract
Vaccinium uliginosum L. (VU) possesses various biological properties, such as antioxidant and protective effects against VU-induced skin photoaging. The purpose of this study is to evaluate the effects of oral administration of a mixture of polyphenols and anthocyanins derived from VU on 2,4-dinitrochlorobenzene- (DNCB-) induced atopic dermatitis (AD) in NC/Nga mice. We assessed anti-AD effects in NC/Nga murine model for a period of 9 weeks. Oral administration of the mixture significantly alleviated the AD-like skin symptoms and clinical signs including ear thickness and scratching behaviors. Orally administrated mixture reduced the level of IgE and IgG1, whereas it increased the level of IgG2a in a dose-dependent manner. The calculated IgG1/IgG2a ratio for each mouse revealed that the mixture derived from VU also significantly reduced the Th2/Th1 ratio, IL-4 and IL-13 (as Th2 cytokines), IFN-γ, and IL-12 (as a Th1 cytokine) in spleens. In addition, it significantly decreased gene expression, such as IL-4, IL-5, CCR3, eotaxin-1, IL- 12, IFN-γ, MCP-1, and IL-17, in AD-like lesions and suppressed Th17. Histological analyses revealed that the epidermis thickness and number of inflammatory cells were significantly reduced. In conclusion, oral administration of the mixture in the DNCB-induced AD is confirmed to improve AD disease in mice.

Abstract
BACKGROUND Effects of probiotics on the prevention of atopic diseases have been proposed recently. Although we have already reported the suppressive effects of the probiotic, ImmuBalance™, on a mouse model for peanuts allergy, its influence on atopic diseases remains unclear. OBJECTIVE Potential efficacy of ImmuBalance™, which is the fermented soy product, on treatment of atopic dermatitis (AD) was investigated using a mouse model for human AD, NC/Tnd mice. METHODS For in vivo study, ImmuBalance containing chow or a control diet were fed to NC/Tnd mice with moderate dermatitis for 2 weeks. Topical application of FK506 ointment was used as a positive control. Clinical skin severity scores, scratching behaviors, trans-epidermal water loss (TEWL), and histological features were analyzed. For in vitro study, suppressive effect of ImmuBalance™ on nerve growth factor (NGF)-activated neurite outgrowth of PC12 cells was examined. RESULTS Clinical skin severity scores of the mice fed with ImmuBalance containing chow were gradually reduced as well as the mice treated with FK506. Feeding with ImmuBalance completely inhibited the increase in scratching behavior of NC/Tnd mice. The value of TEWL of NC/Tnd mice fed with ImmuBalance was significantly decreased. In addition, histological examination revealed that application of ImmuBalance decreased the number of PGP9.5-positive neuronal fibers in the lesional skin. When ImmuBalance extract was added to the culture, NGF-activated neurite outgrowth of PC12 cells was diminished through the inhibition of the phosphatidylinositol 3-kinase phosphorylation. CONCLUSION ImmuBalance could exhibit favorable alterations on AD symptoms, particularly through down regulation of the itch sensation.

Abstract
Platycodi Radix has been used to treat chronic diseases, such as bronchitis, asthma, and hyperlipidemia. In this study, we examined the effect of an aqueous extract, Changkil (CK), from the root of Platycodi Radix on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD)-like skin lesions. Administration of CK onto DNCB-induced AD-like skin lesions in NC/Nga mice ameliorated lesion intensity scores, levels of IgE, thymus and activation-regulated chemokine (TARC), TNF-α, and IL-4 in serum and ears. In contrast, CK increased level of the immunosuppressive cytokine IL-10. Histopathological examination showed reduced thickness of the epidermis/dermis and dermal infiltration of inflammatory cells in the ears. CK also suppressed TNF-α/IFN-γ-induced mRNA expression and production of TARC in HaCaT cells. CK exerts beneficial effects on AD symptoms, suggesting that CK is an effective potential therapeutic agent for AD.

Abstract
BACKGROUND Immunosuppressive environmental chemicals may increase the potency of allergens and thereby play a role in the development of allergic diseases such as allergic rhinitis, asthma and atopic dermatitis (AD). OBJECTIVES This study's primary objective was to examine the mechanisms behind the development of allergic diseases and immunosuppression induced by some environmental chemicals. We focused on the aggravation of AD by the organophosphorus pesticide O,O-diethyl-O-4-nitro-phenylthiophosphate (parathion) and the organochlorine pesticide 1,1,1-trichloro-2,2-bis(4-methoxyphenyl)ethane (methoxychlor), in NC/Nga mice sensitized with extract of Dermatophagoides farinae (Df). METHODS NC/Nga mice were exposed orally to parathion or methoxychlor prior or coinstantaneous with sensitization with Df. The mice were subsequently challenged with Df. One day after the last challenge with Df, we analyzed dermatitis severity and expression of genes in the ear auricle, immunoglobulin (Ig) E and IgG(2a) levels in serum, and in auricular lymph nodes, T- or B-cell numbers and cytokine production. RESULTS Prior exposure to parathion or methoxychlor induced marked increases in the following: dermatitis severity and gene expression in the ear auricle, IgE and IgG(2a) levels in serum, expression of surface antigens on helper T-cell and IgE-positive B-cell, production of Th1 and Th2 cytokines, and production of IgE in auricular lymph-node cells. In contrast, coinstantaneous exposure to parathion or methoxychlor yielded, at most, small but significant decreases in all parameters. CONCLUSIONS Our results indicate that atopic dermatitis can be aggravated by prior exposure to immunosuppressive environmental chemicals.

Abstract
Immunophilin, FK506-binding protein 12 (FK506BP), is a receptor protein for the immunosuppressive drug FK506 by the FK506BP/FK506 complex. However, the precise function of FK506BP in inflammatory diseases remains unclear. Therefore, we examined the protective effects of FK506BP on atopic dermatitis (AD) in tumor necrosis factor-α (TNF-α)/interferon-γ (IFN-γ)-induced HaCaT cells and 2,4-dinitrofluorobenzene-induced AD-like dermatitis in Nishiki-nezumi Cinnamon/Nagoya (NC/Nga) mice using a cell-permeable PEP-1-FK506BP. Transduced PEP-1-FK506BP significantly inhibited the expression of cytokines, as well as the activation of NF-κB and mitogen-activated protein kinase (MAPK) in TNF-α/IFN-γ-induced HaCaT cells. Furthermore, topical application of PEP-1-FK506BP to NC/Nga mice markedly inhibited AD-like dermatitis as determined by a histological examination and assessment of serum IgE levels, as well as cytokines and chemokines. These results indicate that PEP-1-FK506BP inhibits NF-κB and MAPK activation in cells and AD-like skin lesions by reducing the expression levels of cytokines and chemokines, thus suggesting that PEP-1-FK506BP may be a potential therapeutic agent for AD.

Abstract
AIM OF THE STUDY Korean red ginseng (KRG, Panax ginseng C.A. Meyer) has traditionally been considered to harbor anti-allergic effects, however its action on atopic dermatitis (AD) is unclear. Therefore, we investigated the effect of KRG on AD using NC/Nga mice as an AD model. In addition, we examined the effect of aprepitant (substance P specific neurokinin receptor antagonist) on AD. MATERIALS AND METHODS The KRG extract and aprepitant were administered orally to NC/Nga mice. The efficacy of KRG and aprepitant was evaluated by assessing total clinical severity score, ear thickness, serum IgE level and histology. In addition, mRNA and protein expression were measured by real-time RT-PCR and immunohistochemistry, respectively. RESULTS The KRG extract significantly reduced the total clinical severity score, ear thickness and the level of serum IgE in AD mouse model, whereas aprepitant reduced only the serum IgE level. KRG not only decreased TNF-α, IFN-γ and substance P but also reduced the infiltration of FOXP3+ regulatory T (Treg) cells and CD1a+ Langerhans cells in the lesions, whereas aprepitant decreased only substance P and the infiltration of Treg cells. CONCLUSION These results suggest that KRG extract may be a potential therapeutic modality for AD and aprepitant could be used as adjunctive agent to control pruritus in AD.

Abstract
Atopic dermatitis (AD) is the extremely complicated syndrome that various abnormalities develop in a heap. There are various factors in patients for the onset and exacerbation of AD, including genetic cofactors of individuals, environmental factors, the failure of the skin barrier function, unfavorable regulation of the immune system, and the hypersensitivity of sensory nerves. In recent years, there have been many trials of the drug discovery that targets itch, because itch is one of the most serious clinical symptoms of AD. The selection of the suitable animal model that represents the condition of patients, as well as innovative analyzing protocols that can precisely evaluate itch, is indispensable for investigation of an effective drug for AD. In the paper, the unique spontaneous animal model for AD (NC/NgaTnd mice) and the novel quantification system of the laboratory animals that may bring a great progress in the future study of itch are outlined.

Abstract
Prevalence of allergies has increased during the last two decades. Alteration of the gut microbiota composition is thought to play a crucial role in development of atopic diseases. Oral administration of probiotics has been reported to treat and/or prevent symptoms of atopic diseases in infants, but the results are still controversial. We investigated the potential efficacy of dietary interventions by a probiotic strain on prevention and treatment of atopic dermatitis (AD) in a human-like AD model, NC/NgaTnd mice by perinatal administration. Pregnant NC/NgaTnd mice were orally treated with the probiotic strain Lactobacillus rhamnosus CGMCC 1.3724 (LPR), which was followed by treatment of pups until 12 weeks of age. LPR-treated mice exhibited significant lower clinical symptoms of dermatitis, reduced scratching frequency, lower levels of plasma total Immunoglobulin E and higher levels of interferon-gamma in skin biopsies, compared with untreated mice. The protective effect was also observed when mice started to be treated at weaning time (5 weeks of age) even with limited supplementation period of 2 weeks. However, treatment of mice with the probiotic starting 1 week after the onset of the disease (8 weeks of age) had limited effects. The usefulness of LPR for primary prevention of AD was supported.

Abstract
PURPOSE OF REVIEW The classic role of topical and systemic corticosteroids for allergic dermatoses is discussed, with special attention to the impact on the current clinical treatment paradigm by newer systemic and topical therapies. These products are reviewed and recommendations presented on how to effectively assimilate them into clinical practice. RECENT FINDINGS Current knowledge about the etiopathogenesis of atopic dermatitis has resulted in drug development focused on agents with less toxicity than current topical and systemic corticosteroids. Some agents with ceramide/cholesterol/acid combinations demonstrate efficacy in restoring the dysfunctional skin barrier of atopic patients. Concerns resulting from the recent Federal Drug Administration announcement regarding a theoretical risk of cancer associated with topical calcineurin inhibitors are also addressed. Novel therapeutic entities are presented. SUMMARY Patients seeking relief from atopic dermatitis have historically had few really effective and safe therapeutic options. Topical calcineurin inhibitors represent an exciting new therapy for atopic dermatitis without the side-effect profile associated with topical corticosteroids. Nonsteroidal formulations incorporating glycyrrhetinic acid/telmesteine/Vitis vinifera extract and palmitoylethanolamide as 'active' ingredients recently entered the market, stressing antipruritic, antiinflammatory, and skin barrier repair. This confabulates against previously designed topical therapy paradigms. These new products may be used as monotherapy or alternatives to steroid agents.

Abstract
Atopic dermatitis is an especially common and frustrating condition, and the prevalence is increasing. The disease can adversely affect the quality of life of patients and caregivers. Significant advances in our understanding of the pathogenesis have led to improvements in therapy. Patient and caregiver education, avoidance of potential triggering factors, optimal skin care, and pharmacotherapy offer the potential for good control for most patients.

Abstract
Growing evidence has demonstrated the crucial role of NF-kappaB activation on disease severity in allergic disorders. In this study, we examined the clinical relevance of a novel NF-kappaB inhibitor, IMD-0354, for atopic dermatitis (AD) by its topical application. To investigate the in vivo efficacy, 1% IMD-0354 ointment was applied daily to NC/NgaTnd mice with severe dermatitis, which served as a model for human AD. During 2 weeks of treatment, scratching behavior decreased and severity of dermatitis reduced in mice treated with IMD-0354 as well as FK506 without diverse effects. Based on histological examinations, the hyperplasia of keratinocytes and infiltration of inflammatory cells were significantly reduced in the skin of IMD-0354-treated mice. The expressions of T-helper 2 cytokines and tumor necrosis factor-alpha at the affected skin sites were downregulated in IMD-0354-treated mice. Furthermore, IMD-0354 suppressed the proliferation of various immunocompetent cells, neurite outgrowth of nerve growth factor-stimulated pheochromocytoma cells, IgE production from splenic B cells, and IgE-mediated activation of mast cells in vitro. IMD-0354 effectively reduced the allergic inflammation in NC/NgaTnd mice in vivo. Thus, a drug that interferes with NF-kappaB activity may provide an alternative therapeutic strategy for the treatment of AD.
