Abstract
Here, we report the different antioxidant and physiological effects of maghemite nanoparticles (γ-Fe2O3 NPs) obtained using various Fe2+: Fe3+ molar ratios (FM1 = 1: 1, FM2 = 1: 2, and FM3 = 2: 3) via coprecipitation from ferrous/ferric salts. We investigated the physical, optical, and antioxidant properties of FM1, FM2, and FM3 nanoparticles by conducting UV, Raman, FTIR, and EDX spectroscopic analyses along with DPPH radical scavenging activity. Results showed the highest DPPH scavenging activity in the FM2 group (50.76%), while the activity in the FM1 and FM3 groups was 23.60% and 34.63%, respectively. In addition, topical application of nanoparticles induced significant but different anti-inflammatory and immunomodulatory effects in Dermatophagoides farinae extract/2,4-dinitrochlorobenzene (DFE/DNCB)-sensitized BALB/c mice. The FM2 treatment alleviates more effectively the DFE/DNCB-induced atopic dermatitis-like (AD-like) symptoms in mouse ears (edema, excoriation, scaling, and hemorrhage). In comparison with the DFE/DNCB-sensitized mice, FM2 treatment greatly reduced the size and weight of the spleen and the lymph nodes. It also suppressed mast cell infiltration (2-fold) and reduced dermal and epidermal thickness in mice. In addition, FM2 treatment exhibited better inhibition of the mRNA levels of Th1 (IFN-γ and TNF-α) and Th2 cytokines (IL-4, IL-5, IL-6, IL-10, IL-13, and IL-31), as well as the levels of various inflammation-related proteins (COX-2, iNOS, and TNF-α). Moreover, we demonstrated that an increasing proportion of Fe3+ in Fe2+: Fe3+ enhances the antioxidant activity and increases the anti-inflammatory and immunomodulatory effects of γ-Fe2O3 NPs in an AD mouse model. Thus, γ-Fe2O3 NPs could be used in the formulation of nonsteroidal drugs for AD treatment.

Abstract
Atopic dermatitis (AD) is a highly pruritic chronic inflammatory skin disease. Notoginsenoside R1 (NGR1), a unique ingredient of P. notoginseng which is a well-known medicinal herb for its long history of use in traditional Chinese medicine, has been identified to have various biologically active properties that include anti-inflammatory effects. However, the effects of NGR1 on AD remain unclear. Therefore, this study aimed to investigate the effect and mechanism of NGR1 on the in vitro cell model of AD induced by LPS stimulation. RAW264.7 cells were stimulated with 1 μg/ml LPS to establish the in vitro cell inflammation model of AD. RAW264.7 cells were treated with various concentrations of NGR1 (0.1, 1, and 10 μM); then, an MTT assay was performed to determine the cell viability. An ELISA assay detected the levels of pro-inflammatory cytokines (interleukin-1β, IL-1β; interleukin-6, IL-6; tumor necrosis factor-α, TNF-α). Additionally, NO production was measured using a nitrate/nitrite assay kit. Results indicated that LPS induced increases in the levels of TNFα, IL-1β, IL-6, and NO production was significantly reduced by NGR1 treatment in a dose-dependent manner. Further, NGR1 treatment inhibited the activation of the NF-κB pathway, and the NLRP3 inflammasome in LPS stimulated RAW264.7 macrophages. The study data indicated that NGR1 might relieve atopic dermatitis via inhibiting inflammation through suppressing the NF-κB signaling pathway and NLRP3 inflammasome activation.

Abstract
This study aimed to evaluate the effects of cinnamamides on atopic dermatitis (AD) and the mechanisms underlying these effects. To this end, the actions of two cinnamamides, (E)-3-(4-hydroxyphenyl)-N-phenylethyl acrylamide (NCT) and N-trans-coumaroyltyramine (NCPA), were determined on AD by orally administering them to mice. Oral administration of the cinnamamides ameliorated the increase in epidermal and dermal thickness as well as mast cell infiltration. Cinnamamides suppressed serum immunoglobulin (Ig) levels and expression of T-helper (Th)1/Th2 cytokines. Moreover, cinnamamides suppressed interleukin (IL)-4, which plays a crucial role in preparing naïve clusters of differentiation (CD)4+ T cells, and decreased the cervical lymph node size and weight. Interestingly, in almost all cases, NCPA exhibited higher anti-AD activity compared to NCT. These results strongly indicate that NCPA may have potential as an anti-AD agent, and further mechanistic comparative studies of NCT and NCPA are required to determine the cause of differences in biological activity.

Abstract
Flavonols are compounds that have been shown to possess potent anti-inflammatory effects in cellular and animal models of inflammation. In the present study, the anti-inflammatory effects and mechanisms of two natural flavonols, quercetin and galangin, in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages were investigated. It was identified that quercetin and galangin markedly reduced the production of nitric oxide (NO), inducible NO synthase and interleukin-6, and the nuclear translocation of nuclear factor-κB (NF-κB). In addition, LPS-induced activation of extracellular signal-regulated kinase 1/2 (Erk1/2) and c-Jun N-terminal kinase (JNK) was suppressed by quercetin and galangin. Taken together, these data implied that NF-κB, Erk1/2 and JNK may be potential molecular targets of quercetin and galangin in an LPS-induced inflammatory response. Subsequently, the effects of oral administration of quercetin or galangin, either alone or in combination, in a 2,4-dinitrochlorobenzene-induced atopic dermatitis (AD) mouse model were investigated. As a result, measurements of ear thickness and the levels of serum immunoglobulin E, and histological analysis revealed that the two flavonols led to a decrease in inflammation, whereas, in combination, they were even more effective. These results suggested that quercetin and galangin may be promising therapeutic agents for AD. Additionally, their combination may be a novel therapeutic strategy for the prevention of AD.

Abstract
BACKGROUND Moringa oleifera (M. oleifera) is widely cultivated in tropical and subtropical regions and has been used as a vegetable and in traditional medicine. In this study, the anti-atopic dermatitis activity of the ethanol extract of M. oleifera leaf was investigated in vitro and in vivo. METHODS For the in vitro study, HaCaT human keratinocytes were used for cytokines and MAPKinase assay. In the in vivo study, M. oleifera leaf ethanolic extract (MO) was topically applied to BALB/c mice with Dermatophagoides farinae extract (DFE; house dust mite extract)- and 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD). RESULTS The expression of TNF-α, CCL17, IL-1β, IL-6 pro-inflammatory cytokine-related mRNA, and mitogen-activated protein kinases (MAPKs) in TNF-α/IFN-γ-induced HaCaT keratinocytes were reduced by MO. Epidermal and dermal ear thickness, mast cell infiltration, serum immunoglobulin levels, as well as gene expression of various cytokines in the ear tissue, lymph nodes, and splenocytes were improved by treatment with MO. In addition, MO reduced the expression of retinoic acid-related orphan receptor γT (RORγT), thymic stromal lymphopoietin (TSLP), and mannose receptor (CD206) mRNA in the ear tissue and improved cervical lymph node size. CONCLUSION The results of this study strongly suggest the beneficial effects of MO on AD via the regulation of inflammatory responses.

Abstract
BACKGROUND Cytokine responses accompanying sublingual immunotherapy (SLIT) responder phenotypes have not previously been reported. OBJECTIVE To investigate clinical and cytokine responses of house dust mite (HDM) sensitive patients with allergic rhinitis receiving HDM SLIT or placebo for 2 years. METHODS Sixty adults were randomized to receive SLIT or placebo. Clinical symptoms were measured using the Total 5 Symptom Score (TSS5) and Juniper Rhinitis Quality of Life Questionnaire. HDM specific IgE, IgG, skin prick tests, and HDM-stimulated release of interleukin (IL) 5 and interferon γ (IFN-γ) in peripheral blood mononuclear cells was studied at 0, 6, 12, and 24 months and IL-13, IL-4, and IL-10 at 0 and 24 months. RESULTS A total of 32 of 39 SLIT and 16 of 21 placebo patients completed the study. There was significant clinical improvement in both the SLIT and placebo groups. Median T5SS decreased from 14.75 to 5.25 in the SLIT group (P < .001) and 12.7 to 6.0 in the placebo group (P = .003). The median quality-of-life score also decreased in the SLIT group (P < .001) and the placebo group (P < .001). A subgroup analysis of patients found a 60% or greater improvement (on the T5SS and the Juniper Rhinitis Quality of Life Questionnaire) in the good responders group and a 30% to 59% improvement or no improvement in the intermediate responders group. This subgroup analysis also found more good responders in the SLIT group (47%) compared with the placebo group (25%; P = .07). Significant decreases in the IL-5/IFN-γ (P < .001), IL-13/IFN-γ (P < .001), and IL-4/IFN-γ (P = .03) ratios were found in the combined good clinical improvement group at 24 months. CONCLUSION A good clinical response (≥60% improvement in both TSS5 and quality of life) is associated with significant decreases in IL-5, IL-13, and IL-4 relative to IFN-γ during 2 years of SLIT therapy for HDMs.

Down-regulation of FcεRI-mediated CD63 basophil response during short-term VIT determined venom-nonspecific desensitization. PLoS One 2014; 9:e94762.

Abstract
Background We recently showed a desensitization of FcεRI-mediated basophil response after short-term VIT. Our aim was to evaluate the allergen specificity of this desensitization. Methods In 11 Hymenoptera-venom double positive subjects, basophil threshold sensitivity (CD-sens) to anti-FcεRI, honeybee, and Vespula venom was assessed at the beginning and just before the first maintenance dose (MD) of single ultra-rush VIT. In some patients we also monitored CD-sens to rApi m 1 and/or rVes v 5 or other co-sensitizations (i.e., grass pollen). In additional 7 patients, basophils were stripped and sensitized with house dust mite (HDM) IgEs at the same time points. Results We demonstrated a marked reduction of CD-sens to anti-FcεRI and VIT-specific venom before the first MD in all 18 subjects included. Furthermore, in 10 out of 11 double positive subjects, a significant and comparable decrease before the first MD was also evident for non-VIT venom; this nonspecific decrease was further supported by the opposite recombinant species-specific major allergen. In one subject with additional grass pollen allergy, a decrease of CD-sens to grass allergen was also demonstrated. Similarly, in 7 cases of patients with passively HDM-sensitized basophils, a significant reduction of CD-sens was also evident to de novo sensitized HDM allergen. Conclusions Short-term VIT induced basophil desensitization to VIT-specific as well as to VIT-nonspecific venom. As opposed to long-term VIT, which induces venom-specific changes, the effect of short-term VIT seems to be venom-nonspecific.

Abstract
BACKGROUND The precise immunological mechanisms for the early clinical protection of venom immunotherapy (VIT) have not yet been explained. Our aim was to evaluate whether high-affinity IgE receptor (FcεRI) and the related basophil function have a role in the induction of short-term VIT protection. METHODS We included 60 adults and 48 children. Basophil threshold sensitivity (CD-sens) to anti-FcεRI stimulation, and FcεRI gene and cell-surface expression were assessed at the beginning and just before the first maintenance dose (MD) of 100 μg of ultra-rush VIT (day 5) and at the beginning, during buildup, and just before the first MD of 70 μg and of 100 μg of semi-rush VIT (weeks 1-2 and 5). RESULTS We demonstrated a significant reduction in CD-sens to anti-FcεRI stimulation before the first MD in both ultra-rush and semi-rush VIT in all included subjects. FcεRI gene and/or cell-surface expression was decreased in 34-100% of subjects, with different dynamics between VIT protocols. CONCLUSION We found a marked desensitization of FcεRI-activated basophils after short-term VIT. This suppression, which could be highly relevant for the development of early protective mechanisms, might be also related to the changes at the level of FcεRI expression.

Abstract
BACKGROUND We previously reported that prior nasal administration of highly attenuated Bordetella pertussis BPZE1 provides effective and sustained protection against lethal challenge with influenza A viruses. The protective effect was mediated by suppressing the production of major pro-inflammatory mediators. To further explore the anti-inflammatory properties of BPZE1, we investigated the effect of BPZE1 nasal pretreatment on two mouse models of allergic disease, allergic airway inflammation, and contact hypersensitivity (CHS). METHODS Allergic reactions were induced in mice nasally pretreated with live attenuated BPZE1 bacteria using the ovalbumin (OVA)-induced allergic airway inflammation and dinitrochlorobenzene (DNCB)-induced CHS models. RESULTS Prior BPZE1 nasal treatment suppressed OVA-induced lung inflammation and inflammatory cell recruitment and significantly reduced IgE levels and cytokine production. Similarly, BPZE1 nasal pretreatment markedly inhibited ear swelling, skin inflammation, and production of pro-inflammatory cytokines in the DNCB-induced CHS model. For both models, we showed that BPZE1 pretreatment does not affect the sensitization phase. Upon challenge, BPZE1 pretreatment selectively reduced the level of cytokines whose production is increased and did not affect the basal level of other cytokines. Together, our observations suggest that BPZE1 pretreatment specifically targets those cytokine-producing effector cells that are recruited and involved in the inflammatory reaction. CONCLUSION Our study demonstrates the broad anti-inflammatory properties of the attenuated B. pertussis BPZE1 vaccine candidate and supports its development as a promising agent to prevent and/or treat allergic diseases.
