Biological therapies have been developed to target T2\u2010inflammation in asthma. IL\u201013 is a key component of T2\u2010inflammation in asthma, driving mucus hypersecretion, IgE\u2010induction, and smooth muscle contraction. Early phase clinical trials for treatments that target T2\u2010inflammation require biomarkers to assess pharmacological effects. The aim of this study was to examine levels of IL\u201013 inducible biomarkers in the airway epithelium of patients with mild asthma compared to healthy controls. Ten patients with mild asthma with high blood eosinophil and high fractional exhaled nitric oxide (FeNO) were recruited, and six healthy subjects. Blood eosinophil and FeNO reproducibility was assessed prior to bronchoscopy. Epithelial brushings were collected and assessed for IL\u201013 inducible gene expression. Blood eosinophil and FeNO levels remained consistent in both patients with asthma and healthy subjects. Of the 11 genes assessed, expression levels of <jats:italic>15LOX1<\/jats:italic>, <jats:italic>POSTN<\/jats:italic>, <jats:italic>CLCA1<\/jats:italic>, <jats:italic>SERPINB2<\/jats:italic>, <jats:italic>CCL26<\/jats:italic>, and <jats:italic>NOS2<\/jats:italic> were significantly higher in patients with asthma compared to healthy controls. These six genes, present in patients with mild asthma with T2 inflammation, have the potential to be used in translational early phase asthma clinical trials of novel therapies as bronchial epithelial biomarkers.<\/jats:p>","DOI":"10.1111\/cts.13078","type":"journal-article","created":{"date-parts":[[2021,6,9]],"date-time":"2021-06-09T15:18:09Z","timestamp":1623251889000},"page":"1259-1264","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Type\u20102
