Effect of LPS treatment on airway responsiveness and inflammation. (a) Effect of genotype and LPS treatment on lung inflammation assessed by identification of cells harvested from whole-lung lavage. Black bars represent WT LPS-treated mice; white bars represent βarr2–/– LPS-treated mice. Data are mean ± SEM; n = 13–15 mice per group. (b) Airway responsiveness to methacholine, defined by the time-integrated change in peak airway pressure was measured for βarr2–/– (circles) and WT (squares) mice treated with LPS (open symbols) or untreated (filled symbols). Data are mean ± SEM; n = 13–15 mice per group. *LPS treatment caused a similar significant increase in APTI in WT and βarr2–/– mice. P < 0.05.
