Elevated Bcl2L12 levels likely exacerbate eosinophilic infiltration into nasal mucosal tissues by augmenting Th2 cell differentiation and cytokine production, thereby intensifying type 2 inflammation and eosinophilia within nasal mucosal tissues and heightening the risk of CRSwNP recurrence. This evidence concerns the gene BCL2L12 and Increased total eosinophil count.
