From: Human retinal endothelial cells express functional interleukin-6 receptor
Effect of IL-6 on permeability of human retinal endothelial cell monolayers. Results were generated in 5 independent experiments using the expanded cell isolate. A Plots of transcellular electrical resistance across IL-6-treated (red) versus untreated control (blue) cell monolayers, measured as cell index each hour. Arrowheads mark time of IL-6 treatment. Dots represent mean, with error bars indicating standard deviation. n = 3–4 monolayers per condition. B Graphs showing cell index at specified time intervals following IL-6 treatment for corresponding experiments. Bars represent mean, with error bars showing standard deviation. n = 3–4 monolayers per condition. Groups were compared by 2-tailed Student’s t-test: * = p < 0.05; ** = p ≤ 0.01
