Induction by TNF- of IL-6 and IL-8 in Cystic Fibrosis Bronchial IB3-1 Epithelial Cells Encapsulated in Alginate Microbeads

Figure 1

Morphology (a) and viability (insert) of IB3-1 cell monolayers, as determined by bright field and fluorescence photomicrographs. Fluorescence photomicrographs were taken after double staining with Calcein-AM and propidium bromide. Analysis of the release of proinflammatory cytokines by IB3-1 cells, as determinated by Bio-Plex analysis (b,c). The indicated proteins were analyzed in the IB3-1 cell culture medium, namely, IL-1r 𝛼 (Interleukin-1 receptor alpha), G-CSF (Granulocyte-colony stimulating factor), MCP-1 (Monocyte chemotactic protein-1), IL-6 (Interleukin 6), IL-8 (Interleukin 8), RANTES (Regulated upon activation, normal T cell expressed and secreted), and VEGF (Vascular endothelial growth factor). Data are referred to control untreated cells (open bars) and to cells treated for 24 hours with TNF- 𝛼 (80 ng/mL) (closed bars). Data represent the average ± SD ( 𝑁 = 3 ).
