Neonatal exposure with LPS and/or allergen prevents experimental allergic airways disease: development of tolerance using environmental antigens.

BACKGROUND Studies show that children in rural environments develop less asthma and allergic rhinitis than their urban counterparts. This may be a result, in part, of neonatal exposure to environmental antigens such as LPS and/or early exposure to allergens. OBJECTIVE This study examined the effects of neonatal allergen and/or LPS exposure on subsequent… (More)
