Changes of mRNA abundance (Mean ± SEM ΔΔCt1) of immune factors in bMEC stimulated with six heat-inactivated S. aureus strains for 1, 6, or 24 h.

a–eMeans within a row without common superscript letters differ (P*Means differ significantly from negative control.1ΔΔCt values are normalized to negative controls and corrected for the two reference genes, GAPDH and ubiquitin.2IL-1β = interleukin-1β; TNF-α = tumor necrosis factor-α; IL-8 = interleukin-8; RANTES = regulated on activation, normal T cell expressed and secreted; SAA = serum amyloid A; Lf = lactoferrin; GM-CSF = granulocyte-macrophage colony-stimulating factor; COX-2 = cyclooxygenase-2; TLR2 = toll-like receptor 2.3SLAT(−) = S. aureus latex agglutination test negative; SLAT(+) = S. aureus latex agglutination test positive.
