The availability of data on IAQ is limited, as are standardized approaches for evaluating its health impact. This expert review aims to describe the most important indoor air determinants affecting health, and present the IDEAL cluster, which comprises seven EU-funded scientific projects on the topic of IAQ and human health. Across the IDEAL projects, knowledge is generated on exposure to a wide range of indoor air pollutants, including well-known hazards and more explorative chemical and microbiological determinants. The projects will also contribute to the implementation of low-cost and/or real-time sensors on IAQ, as well as advanced chemical and microbiological analyses, and evaluate various interventions to improve IAQ. Several of them focus on particularly vulnerable groups. Raising public awareness and implementing measures to reduce pollutant levels are essential for safeguarding health, particularly in urban areas with elevated pollution levels.","PeriodicalId":122,"journal":{"name":"Allergy","volume":"7 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145663943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the last years, an important body of evidence resulting from mHealth data has led to a better understanding of AR. Such advances have motivated an EAACI-endorsed update of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines (ARIA 2024-2025). This manuscript presents the ARIA 2024-2025 recommendations for intranasal treatments, one of the mainstays for AR management.METHODSThe ARIA 2024-2025 guideline panel issued recommendations following the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) evidence-to-decision framework. Several sources of evidence were used to inform panel judgments and recommendations, including systematic reviews, evaluation of mHealth and pharmacovigilance data, as well as a survey of experts on costs.RESULTSEleven guideline questions concerning intranasal treatments for AR were prioritized, leading to recommendations. Overall, these questions concern the choice between different classes of intranasal medications-most notably, intranasal corticosteroids (INCS), antihistamines (INAH), fixed combinations of INAH+INCS and decongestants-or between different individual medications within each class. Four questions had not been evaluated in previous ARIA guidelines, while for the other three there was a change in the strength or directionality of recommendations. Overall, recommendations point to the suggested use of INAH+INCS over INAH or INCS and INCS over INAH.CONCLUSIONThis ARIA 2024-2025 article supports patients, their caregivers, and healthcare professionals in choosing an intranasal treatment. However, decisions on AR treatment should consider the clinical variability of the disease, patients' values, and the affordability of medications.","PeriodicalId":122,"journal":{"name":"Allergy","volume":"25 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145644890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to assess lung function in HnB and CC users and examine the mechanistic effects of HnB exposure using animal and in vitro models.METHODSSpirometry data from 650 non-smokers (NS), 293 CC smokers, and 49 HnB users enrolled in the Bialystok-PLUS cohort were analyzed. To investigate underlying mechanisms, a whole-body mouse exposure model was performed with HnB aerosol or 3R4F cigarette smoke, assessing lung transcriptomic profiles (by means of RNA sequencing), lung inflammation (by flow cytometry and histochemical staining), and barrier integrity (by using immunofluorescent staining). Moreover, an in vitro ALI-culture model of human airway epithelial cells was used to validate the mouse experiments. The effect of HnB and CC was assessed through cytotoxic effect (MTT and LDH), inflammatory responses (cytokine release by ELISA), and tight junction proteins (immunofluorescence staining).RESULTSpirometric analysis (FEV1, FVC, VC) revealed no significant overall differences in lung function among HnB users, CC smokers, and non-smokers (NS) in the unadjusted comparison. However, subgroup analyses showed that younger (< 45 years) HnB users and those with shorter smoking histories (< 20 years) already exhibited significantly lower FEV1, FVC, and VC compared to NS and CC smokers. After adjustment for age and smoking-related covariates, HnB users displayed modest but significant reductions in static FEV1 and FVC relative to NS, while no adjusted differences were detected between HnB and CC groups, indicating comparable baseline ventilatory function. Both exposures in mice increased eosinophils and B cell counts by ~2-fold, while decreasing ST2+ CD4+ T cells over 80%, and induced epithelial apoptosis. HnB aerosol selectively reduced basophils by almost 50%. Both HnB and CC exposure in mice caused significant epithelial damage and impaired airway barrier function, evidenced by a ~60% reduction in ZO-1. Transcriptomic analysis revealed that CC smoke triggered a robust inflammatory gene response, whereas HnB aerosol predominantly altered metabolic pathways. In vitro, barrier function was impaired under both conditions, but cytokine secretion increased only after CC smoke exposure.CONCLUSIONDespite different molecular impacts, HnB aerosol exposure induces a level of airway epithelial injury and immune cell infiltration comparable to CC smoke. Our findings challenged the narrative of HnB products being a harmless alternative and highlight their potential to cause significant lung pathology.","PeriodicalId":122,"journal":{"name":"Allergy","volume":"151 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145644897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sub-committee assigned names to 112 new allergens with 124 isoallergens/variants as well as 26 new isoallergens/variants of previously named allergens. Most new allergens were respiratory allergens from animals (35 allergens) and plants (25) as well as food allergens from animals (22) and plants (17). Many newly identified allergens reflect globalized allergen exposure and growing research activities outside of Western countries. This is illustrated by allergens from the tropical mite Blomia tropicalis, pollen allergens from tree and weed species native to Asia, and food allergens from regionally important foods such as mango, seafood, silkworm pupae, and natto. The allergen profiles of most relevant sources are well established, but gaps in our knowledge remain, particularly regarding allergens important for populations outside of Europe and North America.

Glycosylation, a post-translational modification, is emerging as a pivotal regulator in T2 inflammation and associated allergic diseases. This review synthesizes current knowledge on glycosylation patterns of key T2 inflammation players, including cytokines, immunoglobulins (e.g., IgE, IgG4) and their receptors, STAT6, mucins, and CTLA-4. We detail how site-specific glycosylation fine-tunes cytokine-receptor interactions, alters signaling pathways, and stabilizes proteins, thereby dictating their bioactivity. Moreover, we examine the enzymatic machinery orchestrating these glycosylation events and the regulatory factors modulating their activity in the context of T2 inflammation. By leveraging these mechanistic insights, we highlight how glycosylation aberrations contribute to food allergy, eosinophilic esophagitis, asthma, allergic rhinitis, and atopic dermatitis, while allergen immunotherapy exploits glycosylation reprogramming (e.g., sialylated IgG4 induction) to restore immune tolerance. Furthermore, we explore the diagnostic and prognostic potential of glycosylation patterns in predicting disease severity and allergen immunotherapy responsiveness, while underscoring the therapeutic promise of targeting glycosylation enzymes or glycan-immune receptor interactions to mitigate T2 inflammation-driven pathologies. A deeper understanding of glycosylation dynamics in T2 inflammation not only enhances our grasp of disease pathogenesis but also opens new avenues for innovative therapeutic interventions.","PeriodicalId":122,"journal":{"name":"Allergy","volume":"4 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145613350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diminishing symptoms and declining inflammation were accompanied by differential expression of genes in peripheral blood mononuclear cells (PBMCs) of 50 egg-allergic children following 8 months of OIT.METHODSHere, we explore the impact of OIT on long non-coding RNA (lncRNA) expression and its downstream effects on allergen-specific immune response with the help of PBMC transcriptome, co-expression gene module identification, pathway enrichment analyses and in vitro stimulation in both PBMC and THP1 cells.RESULTSWe observed 17 lncRNAs which correlated positively with genes involved in IL-13, IL-4, and IL-10 signaling pathways. The same set of lncRNAs correlated negatively with genes playing a role in neutrophil degranulation, phagosome formation, and pyroptosis signaling.

This study tests the hypothesis that mothers born in low‐income countries might have been exposed to diverse microbes—leading to greater diversity and higher levels of transplacental anti‐microbial antibodies, thereby conferring protection against asthma in offspring. Methods In the prospective Boston Birth Cohort, IgG antibody reactome against microbes (2740 species; 1311 genera) was profiled in cord blood, using Phage ImmunoPrecipitation Sequencing. Multinomial regression models were applied to examine the associations of cord blood IgG reactome with child risk of physician‐diagnosed atopy and asthma. Mediation analysis was performed to examine the inter‐relationships among maternal nativity, IgG reactome and risk of developing childhood asthma. Results This report included 943 mother–child dyads enrolled at birth and followed prospectively.
