Title: Steatohepatitis progresses to cancer via immunosuppression of HCC directed CD8+ T cells

Accession Number: GSE90497

Link to Dataset: https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE90497

Repository: Gene Expression Omnibus (GEO)

Data Type(s): Gene Expression

Experiment Type(s): Array expression profiling by high throughput sequencing

Organism(s): Mus musculus

Summary: We show that chronic inflammation and fibrosis in mice with non-alcoholic fatty liver disease (NASH) is accompanied by accumulation of immunoglobulin A (IgA) positive plasmocytes. These cells suppress activation of cytotoxic T cells (CTL) derived from liver infiltrating CD8+ cells. CD8+ T cell ablation greatly accelerates HCC appearance, genetic or pharmacological targeting of IgA and PD-L1 expressing plasmocytes attenuates hepatic carcinogenesis and induces CTL-dependent regression of established HCC.
