How FUT8 levels affect the mucous layer (IMAGE) Center for Genomic Regulation Caption The image shows the mucous layer (in green) by colonic cells in normal conditions (center). In cells without FUT8, the mucous layer is thinner and easily removed by washing (left). Cells with high levels of FUT8, as observed in Ulcerative Colitis patients, produce a more permeable mucus that cannot be washed away. The nucleus of the colonic cells is shown in blue, and the plasma membrane in red. Credit Gerard Cantero Recasense/CRG Usage Restrictions Credit must be given to the creator.
