Abstract
Bovine colostrum is a rich source of bioactive components which are important in the development of the
intestine, in stimulating gut structure and function and in preparing the gut surface for subsequent colonization of microbes.
What is not clear, however, is how colostrum may affect the repertoire of receptors and membrane proteins of the intestinal
surface and the post-translational modifications associated with them. In the present work, we aimed to characterize the surface
receptor and glycan profile of human HT-29 intestinal cells after exposure to a bovine colostrum fraction (BCF) by means of
proteomic and glycomic analyses. Integration of label-free quantitative proteomic analysis and lectin array profiles confirmed
that BCF exposure results in changes in the levels of glycoproteins present at the cell surface and also changes to their
glycosylation pattern. This study contributes to our understanding of how milk components may regulate intestinal cells and
prime them for bacterial interaction.
