Core Fucosylation on T Cells, Required for Activation of T-Cell Receptor Signaling and Induction of Colitis in Mice, Is Increased in Patients With Inflammatory Bowel Disease.

Core fucosylation of the TCR is required for T-cell signaling and production of inflammatory cytokines and induction of colitis in mice. Levels of TCR core fucosylation are increased on T cells from intestinal tissues of patients with IBD; this process might be blocked as a therapeutic strategy.
