Figure 4. The effect of airway smooth muscle integrin α₉β₁ depends on SSAT.

Airway narrowing in lung slices (A and C) and tension in tracheal rings (B and D) from control and α₉smKO mice, either (A and B) untreated or (C and D) treated with control or blocking antibody, in the presence or absence of 50 μM BE3-3-3 for 24 hours. Results (mean ± SEM) are representative of 2 independent experiments (n = 10). *P < 0.01.
