With the aim of defining new, reliable biomarkers, we previously evaluated the potential of 94 genes to differentiate allergic asthma (AA) from nonallergic asthma (NA) based on their expression in peripheral blood mononuclear cells (PBMCs). Here, the most promising biomarkers were further analyzed in a 2-year longitudinal cohort of 24 healthy controls (HCs), 18 NA patients, and 51 AA patients.\nMethods: PBMC samples were collected at the beginning of the study (T0) and 2 years later (T2). The expression of 26 genes was analyzed using RT-qPCR. Genes showing stable expression over time (ie, with a high correlation between T0 and T2) were selected for further analysis. Differential expression and receiver operating characteristic (ROC) curve analysis were used to identify the best biomarkers for discrimination between phenotypes.\nResults: Longitudinal stability was good for 13 genes. Of these, 11 showed statistically significant differential expression between asthma patients and HCs. ROC curve analyses were used to rank these genes by their discriminatory power. Specifically, CPA3 expression was able to discriminate asthma patients from HCs, while LGALS3 and TGF\u00df1 made it possible to differentiate between NA and AA. Additionally, asthma severity was assessed based on the expression levels of RNASE3, IL4R, CHI3L1, PI3, and IL1R2.\nConclusions: We propose a diagnostic algorithm based on the expression profiles of 8 genes in PBMCs that could guide clinicians in the diagnosis and phenotypic classification of asthma.<\/jats:p>","DOI":"10.18176\/jiaci.1168","type":"journal-article","created":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T10:11:37Z","timestamp":1774519897000},"source":"Crossref","is-referenced-by-count":0,"title":["Development of a Panel of Molecular Biomarkers of Asthma: Analysis of Differential Expression and Stability Over Time"],"prefix":"10.18176","volume":"37","author":[{"given":"Luc\u00eda","family":"Cremades-Jimeno","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda","family":"L\u00f3pez-Ramos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Selen","family":"Baos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rub\u00e9n","family":"Fern\u00e1ndez-Santamar\u00eda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda","family":"de Pedro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ignacio","family":"Mah\u00edllo-Fern\u00e1ndez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Rosales-Ariza","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9","family":"Olaguibel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria","family":"del Pozo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda","family":"Caballero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Luna-Porta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Santiago","family":"Quirce","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Blanca","family":"Barroso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diana","family":"Betancor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcela","family":"Valverde-Monge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaqu\u00edn","family":"Sastre","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Blanca","family":"C\u00e1rdaba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7491","published-online":{"date-parts":[[2026,3,26]]},"container-title":["Journal of Investigational Allergology and Clinical Immunology"],"original-title":[],"deposited":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T10:11:37Z","timestamp":1774519897000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jiaci.org\/ahead-of-print\/development-of-a-panel-of-molecular-biomarkers-of-asthma--analysis-of-differential-expression-and-stability-over-time"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,26]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2026,3,26]]}},"URL":"https:\/\/doi.org\/10.18176\/jiaci.1168","relation":{},"ISSN":["1018-9068","1698-0808"],"issn-type":[{"value":"1018-9068","type":"print"},{"value":"1698-0808","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,26]]}}}
