| Outline of Final Research Achievements |
To address the role of AE2 in preventing PBC pathogenesis, we took advantage of our ability to isolate human BEC and autologous splenic mononuclear cells (SMC). We studied the influence of hydrophobic bile acids (GCDC), on AE2 expression in BEC and the subsequent impact on the phenotypes of BEC and local inflammatory responses. We demonstrate herein that GCDC reduces AE2 expression in BEC through induction of ROS, which enhances senescence of BEC. In addition, a reduction of AE2 levels upregulates the production of IL-6, IL-8 and CXCL10 from BEC in response to toll like receptor ligands.
