PAR2-AP-induced mucus secretion in mice.

<p>(A) Images of mucus bubbles in the tracheas of wild type littermates, PAR-2 knock out and targeted ΔF508 CFTR mutant mice 10 min after PAR2-AP stimulation. Scale bar: 0.5 mm. (B) Secretion rates in response to PAR2-AP (100 µM) or carbachol (10 µM) in mouse tracheal glands. Data represent mean ± S.E.M. secretion rates from four to eight mice.
