Mice, divided into the five groups indicated on the left, were either sham-sensitized with PBS or sensitized with OVA. Provocation was carried out by application of OVA in a nebulized form. Mice were treated either during sensitization or during provocation with DMSO (sham; DMSO) or with mepyramine and/or JNJ 7777120.
