Basophil activation tests serve as a method to determine the presence of drug-sIgE, highlighting the importance of optimising the assay. Optimisation involves considering multiple factors to ensure sensitisation helps detect an antigen sIgE. The study investigates the complex factors influencing basophil responsiveness thresholds and aims to provide rules-of-thumb guidance for expected results.</p><p><strong>Methods: </strong>Open and occupied FcεRI receptors were analysed by flow cytometry pre- and postdissociation of surface-bound sIgE. Basophils were then sensitised with serial concentrations of penicillin (BPO)-sIgE in serum or buffer and incubated for 1, 4 and 18 h with or without D₂O and/or IL-3. Basophil sensitivity was evaluated based on FcεRI receptor densities, sIgE/total IgE (tIgE) ratios, responses to BPO(21)-HSA, and D₂O and/or IL-3 effects, with maximal responses determined using anti-IgE human antibodies. These optimised conditions were tested with peanut-sIgE and cat-sIgE sera.</p><p><strong>Results: </strong>Basophils from five donors were used. The FcεRI receptor expression initially averaged 155,000/cell (47,000-344,000/cell), with 35% (5%-79%) unoccupied, which postdissociation increased to 98% (82%-100%) unoccupied. Upon sensitisation, the average reloading with BPO-sIgE was 39% (33%-48%). The ED₅₀ (a measure of cellular sensitivity) was approx. 6000 BPO-sIgE/cell, and the average maximal anti-IgE antibody response was 58% (25%-68%). A 4-h sensitisation at 4°C with IL-3 pretreatment and 70% D₂O allowed the detection of BPO-sIgE/tIgE ratios as low as 0.02%-0.05% without spontaneous histamine release. Under the same conditions, responses were detected with 0.33% peanut-sIgE and 0.1% cat-sIgE ratios.</p><p><strong>Conclusion: </strong>This study outlines a method to assess basophil sensitisation, emphasising the minimum sIgE/tIgE ratio needed for basophil responsiveness. It considers factors like FcεRI open/unoccupied FcεRI receptors, sIgE/tIgE ratios and the effect of D₂O and IL-3. This sets a strong foundation for refining and advancing basophil activation functional assays.</p>","PeriodicalId":10207,"journal":{"name":"Clinical and Experimental Allergy","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sibson","doi":"10.1111/cea.14589","DOIUrl":"10.1111/cea.14589","url":null,"abstract":"&lt;p&gt;‘Growing up’ or ‘toddler’ milks (GUM), marketed for children aged 1–3 years and older, are widely recognised by health bodies as unnecessary and unhealthy. Public health advice is that breastmilk, water, cows' milk or another animal milk should be the main drink for young children from age 1 onwards. Manufacturers claim that GUM are an effective medium to deliver nutrients to young children, especially vitamin D, calcium and iron, which are commonly used to fortify GUM. But GUM are advised against, mainly due to their high free sugars content. UK data show that GUM are the main source of free sugars among those 12- to 18-month-old children who consume them, accounting for half of their total free sugars intake [&lt;span&gt;1&lt;/span&gt;]. In 2011, 36% of children in this age group were GUM consumers. That figure is likely to have risen, because GUM sales are increasing worldwide. Globally, there was a more than twofold increase in GUM sales per child born, from 2005 through 2019 [&lt;span&gt;2&lt;/span&gt;]. In the context of increasing overweight and obesity and high levels of dental decay in young children, increasing GUM sales represent a worrying trend. While marketing of infant formula suitable from 0 to 12 months is strictly regulated in many regions, GUM marketing for children over 12 months has very few restrictions. This is despite World Health Organization recommendations that inappropriate marketing of all commercial milk formulas aimed at children &lt; 36 months old should be prohibited. The lack of regulations means that manufacturers are able to market GUM using misleading nutrition and health claims and in ways which cross-promote infant formula.&lt;/p&gt;&lt;p&gt;One GUM product category that has received much attention recently and appears to be growing in popularity is plant-based GUM. The increase in availability of plant-based GUM reflects a shift in consumption patterns in the general population—away from cows' milk, towards plant-based alternatives [&lt;span&gt;3&lt;/span&gt;]. The nutrient content of plant-based GUM is a cause for concern. Some of the highest-sugar GUM available are plant-based, and a lack of labelling regulation means that consumers are often not aware of the high free sugars content. Indeed, plant-based GUM marketing may misleadingly suggest these products are low in sugar. For example, most oat milks contain free sugars, which are produced by the processing of the oats, where naturally present starch is broken down into sweet-tasting free sugars. This means that an oat milk can claim to have ‘no added sugars’, while containing even more free sugars than a standard cows' milk–based GUM.&lt;/p&gt;&lt;p&gt;Plant-based GUM have low nutritional value in terms of protein concentration or quality and certain micronutrients, compared with animal milks [&lt;span&gt;3&lt;/span&gt;]. Thus, their role in young child feeding is uncertain, but there are clear health hazards associated with many plant-based GUM. In parallel with the shift towards plant-milk consumption, there is widesp","PeriodicalId":10207,"journal":{"name":"Clinical and Experimental Allergy","volume":"54 11","pages":"852-854"},"PeriodicalIF":6.3,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cea.14589","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142603443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
