Background: Inhaled pollutants were recently shown to be responsible for an increased
incidence of airway allergic diseases, including asthma. A common feature of all forms of
asthma is airway hyperresponsiveness. Objective: Our purpose was to elucidate the effects
of diesel exhaust particulate (DEP), one of the most prevalent inhaled pollutants, on airway
responsiveness. Methods: A/J and C57Bl/6 mice were used; the former are genetically
predisposed to be hyperresponsive to acetylcholine, whereas the latter are not. DEP was …
