(author)Oxazolone (OXA) is a potent contact allergen in man, and it is used as a model Th1-allergen to test (Q)SAR's and screening assays for allergenic potential of chemicals. However, it elevates serum IgE levels and Thelper2 cytokines at relatively low doses in test animals, suggesting that it has also respiratory allergenic potential. The lack of...article 2011
