Although this article has focused on the study of peripheral blood expression of IL5RA, in future studies, it would be interesting to analyze in parallel the expression of the membrane-anchored expression (TM-IL-5Rα) isoform in peripheral blood and in nasal tissue from control subjects and nasal polyp (NP) patients, since different expression levels have been previously described for both isoforms [33]. This evidence concerns the gene IL5RA and nasal cavity polyp.
