Abstract

Primary sclerosing cholangitis (PSC) is an autoimmune-like disease of the bile ducts that co-occurs with inflammatory bowel disease (IBD) in almost 90% of cases. Colorectal cancer is a major complication of patients with both PSC and IBD, and these patients are at a much greater risk compared to patients with IBD without concomitant PSC. Combining flow cytometry, bulk and single cell transcriptomics, and T- and B-cell receptor repertoire analysis of right colon tissue from PSC, IBD, and healthy controls we identified a unique adaptive inflammatory transcriptional signature associated with greater risk and shorter time to dysplasia specifically in patients with PSC. This inflammatory signature is characterized by antigen-driven IL-17A+ Foxp3+ CD4 T-cell and IgG-secreting B-cell responses. These data suggest that the mechanisms of PSC and IBD dysplasia are distinct and provide molecular insights to guide prevention of colorectal cancer in PSC.
