Figure 4.

BAT in lung slices from T-bet KO-mice. Baseline airway tone was assessed by β-escin induced relaxation of airways in lung slices. Airways in slices from T-bet KO-mice (black columns) showed an increased baseline airway tone compared to airways in slices from wild-type mice (Balb/C, white columns, n = 28 slices from 5 different mice, * = P < 0.01).
