  abstract     = {{Rationale: Chronic rhinosinusitis with nasal polyps is characterized by a T-helper cell type 2-skewed upper airway inflammation. Mucosal Staphylococcus aureus colonization is found in the majority of patients with nasal polyps. S. aureus is known to induce type 2 cytokine release via enterotoxins. 
Objectives: To investigate the impact of non-enterotoxin-producing S. aureus on type 2 cytokine release. 
Methods: TSLP (thymic stromal lymphopoietin), IL-33, and type 2 cytokines were assessed in a human mucosal tissue model upon S. aureus infection. 
Measurements and Main Results: S. aureus exposure increased the expression of IL-33, TSLP, IL-5, and IL-13 in nasal polyp tissue, accompanied by elevated expression levels of TSLP and IL-33 receptors, predominantly on CD3(+) T cells. S. aureus infection led to the release of TSLP, but not IL-33, IL-5, or IL-13, from healthy inferior turbinate tissue. In contrast, S. epidermidis did not induce any epithelial cell-derived cytokines in nasal polyp or healthy tissue. S. aureus infection also increased the release of IL-33 and TSLP in BEAS-2B epithelial cells, accompanied by activation of NF-kappa B (nuclear factor kB) pathways. Incubation with CU-CPT22, a specific Toll-like receptor 2 antagonist, significantly reduced the S. aureus-induced release of TSLP and IL-33, and the activity of theNF-kappa B signal in BEAS-2B cells. 
Conclusions: This study demonstrates for the first time that S. aureus can directly induce epithelial cell-derived cytokine release via binding to Toll-like receptor 2, and may thereby propagate type 2 cytokine expression in nasal polyp tissue.}},
