Production of TSLPprotein in cell free supernatants by nasal healthy epithelium or nasal polyp epithelium in response to 24 hours exposure to TLR agonists.

Values are shown in pg/mL as average production values from 6 healthy and 5 polyp subjects (b.d. = below detection limit of 1.9 pg/mL). Fold changes (FC) are calculated as a ratio between cytokine production levels in polyposis and healthy tissue.
