Allergens and respiratory pollutants is a collection of 12 authoritative papers that draws upon the collective expertise of world leaders in the fields of innate immunity, immunotoxicology and pulmonary biology. The book critically explores the biological and immunological mechanisms that contribute to immune dysfunction on exposure to allergens and the susceptibility to infectious disease on exposure to ambient pollutants. The clinical relevance of exposure to ambient airborne xenobiotics is critically discussed and collectively, this book provides an educational forum that links the health effects of environmental exposures, immune dysfunction and inflammatory airways disease.
