Regulation of Toll-Like Receptor Expression in Human Conjunctival Epithelial Cells

Figure 3

LPS and PGN stimulated IL-6 and IL-8 secretion in submerged and airlifted primary conjunctival epithelial cells. (a) LPS stimulated IL-6 secretion. (b) LPS stimulated IL-8 secretion. (c) PGN stimulated IL-6 secretion. (d) PGN stimulated IL-8 secretion. IL-6 and IL-8 concentrations were expressed as pg/mL medium/mg total cellular protein. Asterisks (∗) denote significant difference (𝑃<0.05 by paired 𝑡-test) between two groups. 𝑌 error bars represent the standard deviation of the averaged results from 3 different experiments.
