Maternal house dust mite exposure during pregnancy enhances severity of HDM-induced asthma in murine offspring

Atopic status of the mother and maternal exposure to environmental factors is associated with increased asthma risk. Moreover, animal models demonstrate that exposure to allergens in strongly sensitized mothers influences offspring asthma development, suggesting that in utero exposures can influence offspring asthma. However, it is unclear whether maternal exposure to common human allergens like house dust mite (HDM), in the absence of additional adjuvants, influences offspring asthma development.
