Allergic diseases are common and frequently coexist. Allergen immunotherapy (AIT) is a disease-modifying treatment for IgE-mediated allergic disease with effects beyond cessation of AIT that may include important preventive effects. The European Academy of Allergy and Clinical Immunology (EAACI) has developed a clinical practice guideline to provide evidence-based recommendations for AIT for prevention of i) development of allergic comorbidities in those with established allergic diseases, ii) development of first allergic condition and iii) allergic sensitization...

BACKGROUND: Helminth infections, common in low income countries, may protect against allergy-related disease. Early exposure may be key. In the Entebbe Mother and Baby Study, treating helminths during pregnancy resulted in increased eczema rates in early childhood. We followed the cohort to determine whether this translated to increased asthma rates at school-age. METHODS: This randomized, double-blind, placebo-controlled trial, conducted in Entebbe, Uganda, had three interventions...

BACKGROUND: The importance of B lymphocytes to present antigens for antibody production is well documented. In contrast, very little is known about their capacity to influence CD4(+) T cell activation during primary or secondary response to allergens. OBJECTIVE: Using mouse models of asthma, we investigated the role of B cells as antigen presenting cells in propagation and initiation of T helper cell responses. METHODS: Mice were immunized via intranasal route with house dust mite extract (HDM) derived from Dermatophagoides pteronyssinus...

Few studies addressed trans-regional differences in allergen sensitization between areas within a similar latitudinal range but with distinct geomorphological features. We investigated specific IgE (sIgE) positivity to common allergens in populations from two southern China provinces. Using a uniformed protocol, serum samples were collected from 2778 subjects with suspected atopy in coastal Guangdong and inland Yunnan. The overall prevalence of sIgE positivity were 57.8% (95% CI: 56.0%, 59.6%) from Guangdong vs 60...

House dust mite (HDM) is a predominant source of indoor aeroallergen worldwide, which induces allergic diseases including allergic rhinoconjunctivitis, allergic asthma, atopic eczema and other allergic skin diseases. Allergen specific immunotherapy (AIT) is the only potential disease-modifying treatment for HDM allergic subjects. However, AIT remains underused due to no universally accepted allergen standardization and a shortage of rigorous clinical studies to confirm safety and efficacy. With the effort of doctors and researchers in allergy field, efficacy, safety, standardization and strategy of AIT are being continuously developed...

BACKGROUND: Numerous aeroallergens have been associated with the development of asthma, including Alternaria, house-dust mite, and pet dander. Tucson, Arizona, is located in the Sonoran Desert, which has the highest diversity of vegetation of any desert in the world. Given the unique pollen profile in this region, we sought to identify the most common aeroallergens associated with rhinitis and asthma diagnosis in the local adult population. OBJECTIVE: To identify the prevalence of aeroallergen sensitivity in the Tucson adult population and to identify which aeroallergens are associated with a diagnosis of asthma...

BACKGROUND: A clinical history of allergic symptoms and a skin-prick test with house-dust mite crude extracts are standard diagnostic procedures for Dermatophagoides pteronyssinus allergy. Specific immunoglobulin E (IgE) responses to Der p 1 and Der p 2 allergens have been used for the diagnosis of D. pteronyssinus allergy; however, evaluation of the diagnostic performance of Der p 1 and Der p 2 specific IgE (sIgE) produced inconsistent findings. We sought to evaluate the diagnostic accuracy of Der p 1 sIgE and Der p 2 sIgE measurement in the diagnosis of D...

A hallmark of immunity to worm infections and many allergies is a strong type 2 immune response. This is characterized by the production of cytokines interleukin-5 (IL-5) and IL-13 by adaptive T helper 2 (TH2) cells and/or type 2 innate lymphoid cells. Peroxisome proliferator activated receptor-γ (PPAR-γ) is typically regarded as an anti-inflammatory factor. We report that TH2 cells express high levels of PPAR-γ in response to the allergen house dust mite and after infection with the parasite Heligmosomoides polygyrus Mice lacking PPAR-γ in T cells failed to effectively differentiate into IL-5- and IL-13-secreting cells and, hence, did not develop TH2 cell-associated pathologies, including goblet cell metaplasia and eosinophilia, in response to allergen challenge...

Vemuri B Reddy, Ethan A Lerner
Cysteine and serine proteases function via protease-activated (PARs) and mas-related G-protein coupled receptors (Mrgprs) to contribute to allergy and inflammation. Der p1 is a cysteine protease and major allergen from the house dust mite and is associated with allergic rhinitis and allergic asthma. Der p1 activates PAR2 and induces the release of the pro-inflammatory cytokine IL-6 from cells. However, the possibility that Der p1 acts on Mrgprs has not been considered. We report here that ratiometric calcium imaging reveals that Der p1 activates the human receptor MRGPRX1 and the mouse homolog MrgprC11, implicated previously in itch...

Allergen immunotherapy is the only treatment altering the natural course of IgE-mediated allergies. Whereas the subcutaneous route for immunotherapy (SCIT) has been historically considered as a reference, we discuss herein the relative advantages of the sublingual and oral routes as alternatives to SCIT in order to elicit allergen-specific tolerance. The buccal and gut immune systems are similarly organized to favor immune tolerance to antigens/allergens, due to the presence of tolerogenic dendritic cells and macrophages promoting the differentiation of CD4(+) regulatory T cells...

TPL-2 (COT, MAP3K8) kinase activates the MEK1/2-ERK1/2 MAPK signaling pathway in innate immune responses following TLR, TNFR1 and IL-1R stimulation. TPL-2 contributes to type-1/Th17-mediated autoimmunity and control of intracellular pathogens. We recently demonstrated TPL-2 reduces severe airway allergy to house dust mite by negatively regulating type-2 responses. In the present study, we found that TPL-2 deficiency resulted in resistance to Heligmosomoides polygyrus infection, with accelerated worm expulsion, reduced fecal egg burden and reduced worm fitness...
