Primary Nasal Epithelial Cells From Allergic and Non-allergic Individuals Show Comparable Barrier Function.

Previous reports suggested that ex vivo cultured primary nasal epithelial cells from allergic patients differ from those from non-allergic individuals by genuinely reduced barrier function. By contrast, we found that primary nasal epithelial cells from allergic and nonallergic individuals showed comparable barrier function and secretion of cytokines.
