“It was found that PM2.5 + OVA co-exposure significantly enhanced inflammatory cell infiltration, increased higher tracheal secretions in lung tissue and upregulated respiratory resistance response to acetylcholine compared with PM2.5 or OVA single exposure and control groups.”
“It was found that PM2.5 + OVA co‑exposure significantly enhanced inflammatory cell infiltration, increased higher tracheal secretions in lung tissue and upregulated respiratory resistance response to acetylcholine compared with PM2.5 or OVA single exposure and control groups.”
“Here we show that OA inhalation following OA immunization increased airway responsiveness to acetylcholine and induced GM-CSF as well as IL-4 and IL-5 mRNA expression in the lung.”
“Results: Inhalation of OA increased both airway responsiveness to acetylcholine and the number of cells, mostly eosinophils, infiltrated into the airway.”

“ Ovalbumin antigen challenge produced a marked and significant eosinophil accumulation in the BAL fluids and airway hyperresponsiveness to ACh 24 h after the challenge.”

“At 3 h after ozone, OA induced further, but non-significant increases in bronchial responsiveness to ACh , but at 24 h after ozone, there was enhanced responsiveness.”

“IL-5 transgenic mice actively sensitized with ovalbumin displayed more profound airway hyperreactivity in response to acetylcholine 24 h after inhalation challenge with ovalbumin.”

“These results indicate that the sensitization by inhalation of OA produces increased airway responsiveness to ACh in vivo and that this airway responsiveness may be related, at least in part, to the altered airway epithelial functions.”

“After antigen challenge with high dose of OA , LAR occurred in twelve of fifteen animals (80%) and the bronchial responsiveness to acetylcholine was significantly increased.”
