Liver infiltrating T cells regulate bile acid metabolism in experimental cholangitis

In primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC), T cells are likely involved in targeting biliary epithelial cells [1]. Chronic bile duct inflammation leads to cholestasis, biliary fibrosis and potential malignant transformation in the case of PSC [2]. Adaptive immune responses are considered to contribute to early as well as late stages of disease [3]. Numerous genetic risk loci for PBC and PSC were identified that encode for genes involved in adaptive immune responses [4 –6] and portal infiltrates that were predominantly composed of CD4+ and CD8+ T cells have been described in the livers of PBC and PSC patients [7–9].
