Figure 7: Effect of IL-17 on RPE cells.

(A) Change in gene expression following apical IL-17 exposure (5 ng/mL) was measured in mature ARPE-19 cell monolayers. C3 as well as IL-17 expression levels demonstrated an increase in fold change over the control, whereas VEGF and CFH were unaltered. (B) Transepithelial resistance measurements indicated a loss in barrier function in response to apical application of 5 ng/mL IL-17 after four hours. Data shown are average values (±SEM) (n = 3).
