Effect of 24-hour PGE2 pretreatment on iloprost and albuterol signaling in HFL cells. (a) Effect of iloprost (Ilo, 0.1 μM) and albuterol (Alb, 0.1 μM) on fibroblast chemotaxis after PGE2 pretreatment in the presence or absence of PDE4 inhibition with Rof (1.0 μM). (b) Effect of Ilo (0.1 μM) and Alb (0.1 μM) on fibroblast cAMP accumulation after PGE2 pretreatment in the presence or absence of PDE4 inhibition with Rof (1.0 μM). *P < 0.05; **P < 0.01. Bars are means ± SEM; n = 3 separate experiments in all panels.
