Fructose biphosphate aldolase: A new cassava allergen.
Ontology highlight
ABSTRACT: Background
Food allergy has considerably increased in recent years and this situation has been aggravated mainly by the consumption of more processed and complex foods, since minor or potentially allergenic foods are not required to be labeled. Manihot esculenta (cassava) is a widely consumed food in South America, Africa, and Asia and can be used in the production of flour and starch, as well as several other products. This root can cause allergic reactions with symptoms ranging from mild to severe.Methods
Thus, the aim of this study was the characterization of the immunogenic cassava proteins responsible for sensitizing patients allergic to it. Using a 2D-SDS-PAGE based proteomic approach, six proteins were identified, including Fructose Bisphosphate Aldolase (FBA). Recombinant FBA was produced in Expi293 cells and evaluated by immunoblotting with the serum of 10 individual study subjects.Results
Our results showed six cassava IgE-reactive proteins. From those, recombinant fructose bisphosphate aldolase (FBA) showed a positivity of 80% among tested sera, proving to be a highly sensitizing protein.Conclusion
The recombinant FBA molecule obtained in this study can be important for in vivo diagnostic assays, by producing more accurate results, and for desensitization protocols, in which the use of the isolated molecule produces more precise results by avoiding secondary sensitization.Trial registration
All patients signed a consent form approved by the internal ethics committee CAPPesq, Comissão de Ética para Análise de Projetos de Pesquisa do HC FMUSP (CAAE: 10420619.6.0000.0068).
