AB  - Transepithelial transport of proteins is an important step in the immune response to food allergens. Mammalian meat allergy is characterized by an IgE response against the carbohydrate moiety galactosyl-α-1,3-galactose (α-Gal) present on mammalian glycoproteins and glycolipids, which causes severe allergic reactions several hours after red meat consumption. The delayed reaction may be related to the processing of α-Gal carrying proteins in the gastrointestinal tract. The aim of this study was to investigate how protein glycosylation by α-Gal affects the susceptibility to gastric digestion and transport through the Caco-2 cell monolayer. We found that α-Gal glycosylation altered protein susceptibility to gastric digestion, where large protein fragments bearing the α-Gal epitope remained for up to 2 h of digestion. Furthermore, α-Gal glycosylation of the protein hampered transcytosis of the protein through the Caco-2 monolayer. α-Gal epitope on the intact protein could be detected in the endosomal fraction obtained by differential centrifugation of Caco-2 cell lysates. Furthermore, the level of galectin-3 in Caco-2 cells was not affected by the presence of α-Gal glycosylated BSA (bovine serum albumin) (BSA-α-Gal). Taken together, our data add new knowledge and shed light on the digestion and transport of α-Gal glycosylated proteins.

AB  - Red meat allergy is characterized by an IgE response against the carbohydrate galactose-alpha-1,3-galactose (alpha-Gal), which is abundantly expressed on glycoproteins from non-primate mammals. The mechanisms of how alpha-Gal is processed and presented to the immune system to initiate an allergic reaction are still unknown. The aim of this study was to reveal whether the presence of alpha-Gal epitopes on the protein surface influence antigen uptake and processing in immature monocyte-derived dendritic cells (iMDDCs). Immature MDDCs were prepared from healthy blood donors and red meat allergic patients. We found an increased internalization of alpha-Gal carrying proteins over time in iMDDCs by flow cytometric analysis, which was independent of the donor allergic status. The uptake of alpha-Gal carrying proteins was significantly higher than the uptake of non-alpha-Gal carrying proteins. Confocal microscopy revealed alpha-Gal carrying proteins scattered around the cytoplasm in most iMDDCs while detection of proteins not carrying alpha-Gal was negligible. Fluorescent detection of protein on SDS-PAGE showed that degradation of alpha-Gal carrying proteins was slower than degradation of non-alpha-Gal carrying proteins. Thus, the presence of alpha-Gal on the protein surface affects both uptake and degradation of the protein, and the results add new knowledge of alpha-Gal as a clinically relevant food allergen.
