In mice, hydrolysed egg white proteins were shown to offer long lasting desensitization to egg allergy, more effectively than treatment with the intact allergen, through the upregulation of Tfgb1 (TGF-β), Il10, Il17 (IL-17), Foxp3, and Rorc in the small intestinal lamina propria, PPs, and MLNs, and the development of Foxp3+ cells that simultaneously expressed RORγt (34, 161). This evidence concerns the gene IL17A and egg allergy.
