Shellfish Allergy

Shellfish allergy affects 2% of the world’s population and persists for life in most patients. The diagnosis of shellfish allergy, in particular shrimp, is challenging due to the similarity of allergenic proteins from other invertebrates. Despite the clinical importance of immunological cross-reactivity among shellfish species and between allergenic invertebrates such as dust mites, the underlying molecular basis is not well understood. Here we mine the complete transcriptome of five frequently consumed shrimp species to identify and compare allergens with all known allergen sources. The transcriptomes were assembled de novo, using Trinity, from raw RNA-Seq data of the whiteleg shrimp (Litopenaeus vannamei), black tiger shrimp (Penaeus monodon), banana shrimp (Fenneropenaeus merguiensis), king shrimp (Melicertus latisulcatus), and endeavour shrimp (Metapenaeus endeavouri). BLAST searching using the two major allergen databases, WHO/IUIS Allergen Nomenclature and AllergenOnline, successfully identified all seven known crustacean allergens. The analyses revealed up to 39 unreported allergens in the different shrimp species, including heat shock protein (HSP), alpha-tubulin, chymotrypsin, cyclophilin, beta-enolase, aldolase A, and glyceraldehyde-3-phosphate dehydrogenase (G3PD). Multiple sequence alignment (Clustal Omega) demonstrated high homology with allergens from other invertebrates including mites and cockroaches. This first transcriptomic analyses of allergens in a major food source provides a valuable resource for investigating shellfish allergens, comparing invertebrate allergens and future development of improved diagnostics for food allergy.

Type I collagen was described as a major allergen in fish. The purpose of this study was to screen and identify the linear IgE epitopes of type I collagen α1 and α2 subunits in rainbow trout. Five bioinformatics tools were used to predict the potential epitopes and the resultant epitopes were confirmed by LAD2 cells degranulation assay with sera from fish allergic patients. As the result, 10 peptides of α1 and α2 subunits were predicted, respectively, and these peptides were assembled by solid-phase synthesis. 14 epitopes were identified by LAD2 cells degranulation assay, among which, peptide 2, 5–7 were identified as linear epitope of α1 and peptide 11–20 were identified as linear epitope of α2. Moreover, for α1 and α2 subunits, the similarity of sequences was greater than 79%, suggesting the cross-reactivity of fish collagen. The findings of this study provided a strong support for further research of reduction of the collagen allergenicity.
