  • Microorganisms having intestinal cell surface glycosylation modulating action
    Patent number: 8728743
    Abstract: The invention concerns micro-organism strains, in particular of lactic acid bacteria, having a glycosylation modulating effect of intestinal cell surface. The invention also concerns a method for selecting micro-organism strains, in particular of lactic acid bacteria, which consists in measuring the average fluorescence intensity variation of HT29-MTX cells incubated in the presence of a lectin coupled with a fluorochrome after being in contact with the supernatant of the strain concerned. Said lactic acid bacteria strains can be used, optionally in the form of their active fraction, for preparing food compositions or medicines or food supplements, modulating glycosylation of glycoproteins of intestinal epithelial cells.
    Type: Grant
    Filed: November 16, 2005
    Date of Patent: May 20, 2014
    Assignee: Compagnie Gervais Danone
    Inventors: Jean-Michel Antoine, Miguel Freitas, Chantal Cayuela, Germain Trugnan
