We investigated the effects of S-777469 (1-[[6-Ethyl-1-[4-fluorobenzyl]-5-methyl-2-oxo-1, 2-dihydropyridine-3-carbonyl]amino]-cyclohexanecarboxylic acid), a novel cannabinoid type 2 receptor (CB2) agonist, on 1-fluoro-2,4-dinitrobenzene (DNFB)-induced ear inflammation and mite antigen-induced dermatitis in mice. The oral administration of S-777469 significantly suppressed DNFB-induced ear swelling in a dose-dependent manner. In addition, S-777469 significantly alleviated mite antigen-induced atopic dermatitis-like skin lesions in NC/Nga mice...

BACKGROUND: Asthma is a common chronic lung disease characterized by airflow obstruction, airway hyperresponsiveness (AHR) and inflammation. IGFs have been reported to play a role in asthma but little is known about how the Insulin-like Growth Factor 1 Receptor (IGF1R) affects asthma pathobiology. METHODS: Female Igf1r-deficient and control mice were intranasally challenged with house dust mite (HDM) extract or PBS five days per week for four weeks. Lung function measurements, and bronchioalveolar lavage fluid (BALF), serum and lungs were collected on day 28 for further cellular, histological and molecular analysis...

Sheenal Patel, Rebecca Gruchalla
The hygiene hypothesis began as an attempt to explain the relatively rapid rise in atopic diseases. Strachan's early hypothesis regarding the role of family size and exposure to early childhood infections in the development of atopic diseases has clearly evolved to integrate the possible effects of hygiene, eradication of parasitic infections, immunizations, improvements in home heating and ventilation, dust mite exposure, breastfeeding duration, diet, parental smoking, pollution, and exposure to pets and farm animals...

The coffee berry borer (CBB) Hypothenemus hampei is the most limiting pest of coffee production worldwide. The CBB genome has been recently sequenced; however, information regarding the presence and characteristics of transposable elements (TEs) was not provided. Using systematic searching strategies based on both de novo and homology-based approaches, we present a library of TEs from the draft genome of CBB sequenced by the Colombian Coffee Growers Federation. The library consists of 880 sequences classified as 66% Class I (LTRs: 46%, non-LTRs: 20%) and 34% Class II (DNA transposons: 8%, Helitrons: 16% and MITEs: 10%) elements, including families of the three main LTR (Gypsy, Bel-Pao and Copia) and non-LTR (CR1, Daphne, I/Nimb, Jockey, Kiri, R1, R2 and R4) clades and DNA superfamilies (Tc1-mariner, hAT, Merlin, P, PIF-Harbinger, PiggyBac and Helitron)...

REVIEW
P Zieglmayer
The clinical efficacy of allergen-specific immunotherapy depends on tolerance induction. Treatment success is currently limited by treatment-related adverse reactions. Novel approaches mainly target improvement of tolerability in addition to optimized immunogenicity. For epicutaneous immunotherapy (EPIT), commercially available treatment extracts are applied to skin via a patch. The route exhibits excellent tolerability and good clinical efficacy. The first encouraging data on a peanut EPIT were published in 2016...

Placebo effects play an important role in the treatment of allergic diseases. Therefore, in this study, we analysed the described effects of placebo in all double-blind placebo-controlled clinical trials of allergen-specific immunotherapy (ASIT) with inhalant allergens (birch, grass, house dust mites) listed in the tables (updated July 2016) attached to the German S2k guideline on allergen-specific immunotherapy in IgE-mediated allergic diseases. The most common placebo consisted of verum without allergen, but when the subcutaneous route was used, histamine was sometimes added...

BACKGROUND: The prevalence of sensitization varies geographically based on multiple environmental factors including humidity. The aim of this study was to determine the prevalence of atopy in symptomatic adults. More importantly we aimed to obtain a regional statistic of sensitization to common allergens given Saskatchewan's dry climate. METHODS: One thousand consecutive symptomatic adults were screened for atopy via skin prick test over 10 years (2006-2016) in the Division of Respirology...

BACKGROUND: Atopic status of the mother and maternal exposure to environmental factors is associated with increased asthma risk. Moreover, animal models demonstrate that exposure to allergens in strongly sensitized mothers influences offspring asthma development, suggesting that in utero exposures can influence offspring asthma. However, it is unclear whether maternal exposure to common human allergens like house dust mite (HDM), in the absence of additional adjuvants, influences offspring asthma development...

The prevalence of allergic rhinitis (AR) and asthma has been increasing, and the comorbidity rates of these diseases are very high. Here, 176 AR patients, 124 patients with comorbid AR and asthma (AR-A) and 206 healthy Chinese children as controls were included in a case-control study. Six single-nucleotide polymorphisms (SNPs), miR-146a (rs2910164, rs57095329 and rs6864584), miR-196a2 (rs11614913), miR-499 (rs3746444) and miR-149 (rs2292832), were genotyped. The prevalence of homozygous miR-149 (rs2292832) CC genotype and C allele were considerably increased in AR and AR-A patients, compared with the controls...

Social immunity is a key factor for honeybee health, including behavioral defense strategies such as the collective use of antimicrobial plant resins (propolis). While laboratory data repeatedly show significant propolis effects, field data are scarce, especially at the colony level. Here, we investigated whether propolis, as naturally deposited in the nests, can protect honeybees against ectoparasitic mites Varroa destructor and associated viruses, which are currently considered the most serious biological threat to European honeybee subspecies, Apis mellifera, globally...

Climatic and biome changes of the past million years influenced the population structure and genetic diversity of soil-living arthropods in Europe. However, their effects on the genetic structure of widespread and abundant soil animal species such as the Collembola Parisotoma notabilis remain virtually unknown. This generalist and parthenogenetic species is an early colonizer of disturbed habitats and often occurs in human modified environments. To investigate ancient climatic influence and recent distributions on the genetic structure of P...
