To determine whether GILT might influence the MHCII-restricted response to additional asthma-linked allergens, indicating a potentially more general role for GILT in asthma, we performed recall proliferation assays using the cockroach allergen Bla g 2 [20] and the house dust mite allergen Der f 1, which both contain disulfide bonds (Table 1). This evidence concerns the gene IFI30 and asthma.
