This project aimed to improve hazard identification of respiratory chemical allergens, as is presently being done by measuring proliferation and cytokine production in local lymph nodes and IgE in serum upon dermal application of the chemical in question. To this end respiratory allergy endpoints, induced by the respiratory allergen trimellitic anhydride (TMA), were characterised by whole genome analysis of lung tissue and blood proteomics. The endpoints were compared to those induced by the contact allergen dinitrochlorobenzene (DNCB). TMA induced up-regulation of genes for allergy-associated chemokines and inflammatory-associated genes including those associated with lung-remodelling. In addition, genes involved in down-sizing inflammation were activated. Bloodproteomics reflected activation of inflammation-down-sizing mechanisms. DNCB also up-regulated genes for allergy-associated chemokines, but not for lung remodelling and inflammation-down-sizing mechanisms.
It is concluded that parameters for lung remodelling are a promising tool in hazard identification of by low molecular weight (LMW) respiratory allergens. The results suggest also that, as long as inflammation-down-sizing mechanisms are present, chronic asthma may not occur.
