Effects of hardwood smoke exposure on allergic airway inflammation in mice.

Hardwood smoke (HWS) from wood burning stoves and fireplaces can be a significant contributor to the composition of ambient air pollution. We hypothesize that the inhalation of HWS by ovalbumin (OVA)-sensitized mice with preexisting lung inflammation leads to the exacerbation of allergic airway responses. Two different models were employed to characterize the effects of inhaled wood smoke on allergic airway inflammation.
