We propose a novel sublingual immunotherapy for peach allergy, using systems, that combine Prup3-T-cell peptides with mannose dendrons (D1ManPrup3 and D4ManPrup3). Peach anaphylactic mice were treated 1, 2 and 5 nM concentrations. Tolerance was assessed one/five weeks after finishing treatment by determining in vivo/in vitro parameters after challenge with Prup3. Only mice receiving D1ManPrup3 at 2 nM were protected from anaphylaxis (no temperature changes, decrease in Prup3-sIgE and -sIgG1 antibody levels, and secreting cells) compared to PBS-treated mice. Moreover, an increase of Treg-cells and regulatory cytokines (IL-10+/IFN-γ+) in CD4+-T-cells and DCs were found. These changes were maintained at least five weeks after stopping treatment. D1ManPrup3 is an effective new approach of immunotherapy inducing protection from anaphylaxis which persists after finishing treatment. 10.1038/s41598-019-40114-7 2045-2322 Scientific reports http://hdl.handle.net/10668/13688 30858392 http://hdl.handle.net/20.500.12105/17828 Glycosylated nanostructures in sublingual immunotherapy induce long-lasting tolerance in LTP allergy mouse model.
