From: The novel TRPA1 antagonist BI01305834 inhibits ovalbumin-induced bronchoconstriction in guinea pigs
The impact of TRPA1 antagonist treatment (1 mg.kg−1 BI01305834) on the dose of ovalbumin (OA) required to induce respiratory distress and an increase in Ppl of more than 100%. Animals were exposed to increasing concentrations of ovalbumin and the cumulative dose needed for individual animals is plotted, P = 0.17 (Mann–Whitney U test). (Veh = 11 animals, BI = 13 animals)
