Results of the mass spectrometry analysis to assess bioactive peptides are shown. The top grey bar displays the sequence of the BLG, the main allergenic protein of the whey. All the peptides in the pHF-W1 and derived from BLG are represented by the red bars. Blue bars identify the peptides that were presented by the antigen-presenting cells. Previously published peptides position identified by Pecquet et al., 2015 [15], Meulenbroek et al., 2013 [23], and Gouw et al. 2018 [24], as being tolerogenic are displayed in orange (a). Exact sequences of the 9 core peptides identified are shown (b).
