FIG. 4.
Effect of roxithromycin (RXM) on ICAM-1 expression on Bet-1A cells. Confluent Bet-1A cells were treated with IFN-γ and roxithromycin. After 18 h, the expression of ICAM-1 molecules was evaluated by cell ELISA. Roxithromycin inhibited the magnitude of ICAM-1 expression in a concentration-dependent fashion. ∗, P < 0.05 (ANOVA; n = 4); OD, optical density.
