The “epithelial barrier theory” suggests that genetic predisposition and exposure to diverse factors damaging the epithelial barriers contribute to the emergence of allergic and autoimmune conditions. Impaired epithelial barriers, microbial dysbiosis, and tissue inflammation have been observed in a high number of mucosal inflammatory, autoimmune and neuropsychiatric diseases, many of which showed increased prevalence in the last decades. Pets, especially cats and dogs, share living spaces with humans and are exposed to household cleaners, personal care products, air pollutants, and microplastics. The utilisation of cosmetic products and food additives for pets is on the rise, unfortunately, accompanied by less rigorous safety regulations than those governing human products. In this review, we explore the implications of disruptions in epithelial barriers on the well-being of companion animals, drawing comparisons with humans, and endeavour to elucidate the spectrum of diseases that afflict them.

Although the mechanistic understanding is poor, inhibition of IL‐4Rα and IL‐4/IL‐13 signaling improves loss of smell in CRSwNP patients. In the present study, we compare the effects of IL‐4, IL‐13, and IL‐4Rα blockade on murine olfaction and identify the underlying pathophysiological mechanisms of loss of smell.MethodsTo evaluate the effects of IL‐4 and IL‐13 on olfactory function, we administered these cytokines intranasally to BALB/c mice for 5 consecutive days and assessed their latency to find hidden food. Calcium uptake assays were conducted to measure olfactory neuronal activity in vitro and ex vivo. We also performed histological analyses, proteomics, bulk RNA sequencing, and single‐cell RNA sequencing to assess the impact of IL‐4, IL‐13, and IL‐4Rα blockade on the olfactory epithelium and to identify potential molecular or cellular correlations with smell loss in human CRSwNP patients.ResultsHere, we provide evidence for non‐redundant effects of IL‐4 and IL‐13 in olfaction, with loss of smell in mice evoked by intranasal administration of IL‐4, not IL‐13. We demonstrate that an IL‐4–IL‐4Rα axis has a direct functional impact on murine olfactory sensory neurons and evokes inflammatory cell infiltration and pathophysiologic modulation of unique molecular signatures in olfactory epithelium without compromising structural integrity. Furthermore, single‐cell analysis of olfactory epithelium reveals that IL‐4–IL‐4Rα signaling modulates neuronal crosstalk with mast cells, macrophages, and NK cells, suggesting a functional link between olfactory impairment and neuroinflammation.ConclusionCollectively, this study suggests that an IL‐4–IL‐4Rα signaling axis plays a unique pathophysiological role in olfactory dysfunction via direct effect on neurons and modulation of neuroimmune interactions.","PeriodicalId":122,"journal":{"name":"Allergy","volume":"1 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142448211","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}

It is now recognized that the immune response underlying eosinophilic asthma involves a complex network of interconnected pathways from both the adaptive and innate immune systems. Within this response, interleukin-5 (IL-5) plays a central role in eosinophil differentiation, activation and survival and has emerged as a key target for therapies treating severe asthma. The monoclonal antibodies mepolizumab and reslizumab target the ligand IL-5, preventing its interaction with eosinophils; in contrast, benralizumab binds to the IL-5 receptor (IL-5R), preventing IL-5 from binding and leading to substantially greater eosinophil reduction by enhanced antibody-dependent cell-mediated cytotoxicity. Although no direct head-to-head clinical trials of asthma have been published to formally evaluate the clinical significance of these different therapeutic approaches, the potential benefits of partial versus complete eosinophil depletion continue to remain an important area of study and debate.
