CD73 deletion in HNF1B-expressing metaplastic pancreatic epithelium during caerulein-induced chronic pancreatitis worsens injury and fibrosis and disrupts ADM recovery.
- Why it matters: It is unclear what determines whether acinar-to-ductal metaplasia resolves or persists with ongoing inflammation and scarring, shaping downstream disease risk.
- What they did: Single-cell RNA-seq from chronic pancreatitis enriched Nt5e (CD73) in Hnf1beta ADM; mice with CD73fl/fl;Hnf1bCreERT2 received 4 weeks of caerulein, then tamoxifen to delete CD73, followed by histology, immune profiling, and ex vivo ADM assays.
- The result: Metaplasia-specific CD73 loss increased ADM formation and MCP-1 and TIMP-1 production, and in vivo exacerbated fibrosis while altering inflammatory cell abundance and spatial organization, implying CD73 regulates epithelial-immune remodeling during repair.
