Although the prevailing theory suggests that immunoglobulin E (IgE)-mediated type I allergies are the primary cause of ATRs, the IgE-mediated pathway has rarely been demonstrated. Furthermore, despite accumulating reports suggesting the role of allergic predispositions to food and inhaled antigens, the etiology of ATR has yet to be fully elucidated. The recent introduction of the basophil activation test (BAT) and passive immune BAT into transfusion medicine has provided novel insights into these issues.<\/p>\n<p>PMID:<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/40840009\/?utm_source=SimplePie&amp;utm_medium=rss&amp;utm_content=8900118&amp;ff=20250822004703&amp;v=2.18.0.post9+e462414\">40840009<\/a> | DOI:<a href=\"https:\/\/doi.org\/10.1016\/j.coi.2025.102644\">10.1016\/j.coi.2025.102644<\/a><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Curr Opin Immunol. 2025 Aug 20;96:102644. doi: 10.1016\/j.coi.2025.102644.
