INTRODUCTION: Prostaglandin D2 (PGD2), which is produced mainly by Th2 cells and mast cells, promotes a type-2 immune response by activating Th2 cells, mast cells, eosinophils, and group 2 innate lymphoid cells (ILC2s) via its receptor, chemoattractant receptor-homologous molecules on Th2 cells (CRTH2). However, the role of CRTH2 in models of airway inflammation induced by sensitization without adjuvants, in which both IgE and mast cells may play major roles, remain unclear. METHODS: Wild-type (WT) and CRTH2-knockout (KO) mice were sensitized with ovalbumin (OVA) without an adjuvant and then challenged intranasally with OVA...

INTRODUCTION: Mast cells are known for their involvement in allergic reactions but also in inflammatory reactions via secretion of numerous pro-inflammatory chemokines, cytokines, and enzymes. Drug development has focused on antiproliferative therapy for systemic mastocytosis and not on inhibitors of mast cell activation. The only drug available as a "mast cell blocker" is disodium cromoglycate (cromolyn), but it is poorly absorbed after oral administration, is a weak inhibitor of histamine release from human mast cells, and it develops rapid anaphylaxis...

INTRODUCTION: Epithelial barrier disruption is the initial cause of various diseases. We previously reported that acupoint catgut embedding (AE) improves tight junction proteins (TJs) in rats with allergic rhinitis. However, whether AE improves the epithelial barrier in local allergic rhinitis (LAR) remains unknown. METHODS: A total of 36 Sprague Dawley (SD) male rats aged 5-7 weeks were divided into 6 groups with 6 rats each: control group, LAR model group, false acupoint embedding + LAR group, acupoint embedding + LAR group, capsaicin + LAR group, and tunicamycin + acupoint embedding + LAR group...

INTRODUCTION: The muscarinic M3 receptor antagonist, tiotropium, has a bronchodilatory effect on asthma patients. Additionally, tiotropium inhibits allergic airway inflammation and remodeling in a murine asthma model. However, the underlying mechanisms of this M3 receptor antagonist remain unclear. Therefore, we investigated the effect of muscarinic M3 receptor blockage on M2 macrophage development during allergic airway inflammation. METHODS: BALB/c mice were sensitized and challenged with ovalbumin to develop a murine model of allergic airway inflammation mimicking human atopic asthma...

INTRODUCTION: Aspergillus fumigatus is the most common airborne allergen of the Aspergillus family. However, allergies to Aspergillus spp. are increasing, and subsequently, allergies to Aspergillus species other than fumigatus are also on the rise. Commercial diagnostic tools are still limited to Aspergillus fumigatus. Hence, there is a need for improved tests. We decided to investigate the correlation between serological sensitization to A. fumigatus and other Aspergillus species. METHODS: Hundred and seven patients with positive skin prick tests to A...

INTRODUCTION: IgE-mediated peanut allergy is an important public health problem of increasing prevalence leading to anaphylactic reactions both in children and adults. Allergen-specific oral immunotherapy (OIT) is the single treatment with the potential capacity to modify the course of the disease, but it still faces some drawbacks in terms of efficacy, safety, patients' adherence, and cost. Alternative strategies, including the use of novel adjuvants, to overcome such limitations are highly demanded...

INTRODUCTION: While a consensus seems to have been reached with regard to the definition of anaphylaxis, there is no universal instrument for scoring allergic reaction severity despite more than 30 having been proposed by the time of writing. This severely hampers comparison of data between studies. While scales have been compared with regard to their utility in grading food-related reactions, no such comparisons have been made for Hymenoptera venom-associated reactions. METHODS: The study conducted a retrospective analysis to compare the severity of Hymenoptera venom allergy reactions in 104 participants with suspected Hymenoptera venom allergy...
