Protective and reparative effects of peptides from soybean β-conglycinin on mice intestinal mucosa injury

Abstract Peptides derived from alcalase digestion of soybean β-conglycinin, containing 8.52% carbohydrate, exhibits an inhibition effect on pathogen adhesion or translocation to intestinal cells in vitro. In this study, the protective and reparative effects of β-conglycinin peptides on intestinal mucosa injury in vivo were studied using mice with dextran sulfate sodium (DSS)-induced intestinal mucosa injury. The results showed that β-conglycinin peptides contained approximately 21.77% glutamic acid (Glu), and significantly reduced the histological injury in mice both in the protective and reparative experiments. The myeloperoxidase activity of mice treated with β-conglycinin peptides decreased compared with those treated DSS in the positive control group. Immunohistochemical analysis also showed that β-conglycinin peptides inhibited the expression of inflammatory factor NF-κB/p65. These results suggested that peptides derived from soybean β-conglycinin exhibited protective and reparative effects on mice intestinal mucosa injury.
