CD8 T cells primed in the gut‐associated lymphoid tissue induce immune‐mediated cholangitis in mice
Daniel Seidel, Ira Eickmeier, Anja A. Kühl, Alf Hamann, Christoph Loddenkemper, Eckart Schott – 26 August 2013 – The pathogenesis of primary sclerosing cholangitis (PSC) remains poorly understood. Since PSC predominantly occurs in patients with inflammatory bowel disease, autoimmunity triggered by activated T cells migrating from the gut to the liver is a possible mechanism. We hypothesized that T cells primed in the gut‐associated lymphoid tissue (GALT) by a specific antigen migrate to the liver and cause cholangitis when they recognize the same antigen on cholangiocytes.
