activation of fasfasl pathway and the role of c flip in primary culture of human cholangiocarcinoma cells

iCCA cells express high levels of Fas and FasL that increase after co-culture with PBMCs inducing apoptosis in CD4+, CD8+ T-cells and in CD56+ NK-cells. In vitro, c-FLIP is expressed in iCCA cells and the co-culture with PBMCs induces an increase of c-FLIP in both iCCA cells and biliary tree stem cells. With this background,...
