It is noteworthy that quinolones (Qs) have been observed to predominantly trigger immediate hypersensitivity reactions (IHRs). These reactions are categorized as either IgE-mediated or non-IgE-mediated, attributable to the off-target occupation of the recently described receptor, Mas-related G-protein coupled receptor member X2 (MRGPRX2), on effector cells. The increasing trend of HRs underscores the necessity for enhanced diagnostic and management strategies. The present position paper aims to shed light on the key mechanisms involved in immediate and non-immediate QHRs. The clinical spectrum of these reactions is discussed, as well as the utility of skin tests, in vitro diagnostic tests, and drug provocation tests in diagnosis. A further focal point of this study is the analysis of cross-reactivity between various Qs. The paper concludes with the presentation of diagnostic algorithms for both immediate and non-immediate QHRs. The paper's findings aid clinical practice for QHRs and address unmet needs, which should stimulate more in-depth investigations into the mechanisms and clinical practice of QHRs.","PeriodicalId":122,"journal":{"name":"Allergy","volume":"16 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032119","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}

Understanding microenvironment-primed immune responses is essential to elucidate the phenotypic/functional changes MCs undergo, and thus understand their contribution to diseases and predict the most effective therapeutic strategies. We exposed primary human MCs to cytokines mimicking a T1/pro-inflammatory (IFNγ), T2/allergic (IL-4 + IL-13), alarmin-rich (IL-33) and pro-fibrotic/pro-tolerogenic (TGFβ) microenvironment. We investigated MC surface receptor expression, activation, cytokine, histamine, and prostaglandin D2 release, and performed transcriptomics to define shared and unique genetic features. Using machine learning, we extracted minimal cytokine-activated signatures and performed gene set variation analysis (GSVA), single-cell clustering, and pseudotime analyses on tissue MCs from skin and respiratory diseases. MCs exposed in vitro to IFNγ acquire an antigen-presenting phenotype (HLA-DR+), increase IgE-mediated responses and histamine release, while TGFβ inhibits activation and boosts integrin αvβ3 expression. IL-33 primarily drives cytokine (GM-CSF, IL-5, IL-10, IL-13) and chemokine production (IL-8, MCP-1, MIP-1α) and facilitates mixed IgG-IgE responses. Among uniquely expressed genes, 245 were highly informative to discriminate cytokine-primed MCs. GSVA revealed MC IL-4 + IL-13 signatures enriched in atopic dermatitis and psoriasis, IFNγ in COVID-19 infection and cystic fibrosis, IL-33 in COVID-19 and chronic obstructive pulmonary disease (COPD) and TGFβ in pulmonary fibrosis (PF) and chronic rhinosinusitis. Furthermore, we detected positive IL-33/TGFβ priming in eosinophil-high COPD. Minimal cytokine-activated signatures identified disease-cytokine-specific MC clusters and pseudotime trajectories, suggesting involvement of MCs in fibrosis (COPD/PF), T1/alarmin-driven inflammation (COVID-19) and mixed T1/T2 inflammatory responses (AD/psoriasis). In conclusion, in cytokine-driven settings, MCs are phenotypically and functionally diverse. Thus, unique MC signatures will help to identify cytokine-primed MCs and predict the efficacy of anti-cytokine treatment in MC-driven diseases.","PeriodicalId":122,"journal":{"name":"Allergy","volume":"24 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025417","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}

Whilst literature on the topic remains slim, the majority of existing research has highlighted the potential risks, such as transmission of infections. Although the concerns are valid, potential beneficial aspects have, until now, received less attention. These benefits are hypothesised to include exposure to a healthy, balanced oral microbiome, in combination with the anti-inflammatory properties of saliva and the pre-digestion of food by salivary enzymes. The hypothesis is supported by various studies that have shown the importance of early exposure to microbes for the development of the child's immune system. Moreover, a more varied microbiome earlier on in life is assumed to reduce the development of atopic diseases. Provided that the person chewing and its receiver/the child are healthy, premastication could offer a simple, well-rehearsed method to shape the child's immune system with health-promoting effects particularly in regard to primary allergy prevention. The interactive benefits of transferring an immune-stimulating pre-digested soft food portion containing small amounts of (diverse) food proteins via the oral route could be a valuable contribution to oral tolerance development in the decisive period of microbial-driven immune system maturation. This review aims to evaluate the risks but especially the potential benefits of premastication, by focussing on its possible implications in (food) allergy prevention and oral tolerance development.</p>","PeriodicalId":122,"journal":{"name":"Allergy","volume":"80 10","pages":"2726-2737"},"PeriodicalIF":12.0,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/all.16676","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
