Protein modifications such as oligomerization and tyrosine nitration can impact the immune response to allergens and contribute to the prevalence of allergic diseases. This mini-review examines the effects of tetranitromethane, peroxynitrite, ozone, and nitrogen dioxide on the major birch and grass pollen allergens Bet v 1 and Phl p 5. It explores the mechanisms of tyrosine nitration and the formation of protein dimers and higher oligomers, as well as the resulting immunological effects.
Protein modifications such as oligomerization and tyrosine nitration alter the immune response to allergens and may contribute to the increasing prevalence of allergic diseases. In this mini-review, we summarize and discuss relevant findings for the major birch and grass pollen allergens Bet v 1 and Phl p 5 modified with tetranitromethane (laboratory studies), peroxynitrite (physiological processes), and ozone and nitrogen dioxide (environmental conditions). We focus on tyrosine nitration and the formation of protein dimers and higher oligomers via dityrosine cross-linking and the immunological effects studied.
