    Overlap syndromes in autoimmune liver diseases exhibit unique immunopathogenic mechanisms distinct from classical AIH and PBC.

  • 2

    Approximately 10% to 20% of patients with overlap syndromes show therapeutic resistance, risking progression to end-stage liver disease.

  • 3

    Recent single-cell transcriptomic studies reveal specific immune cell signatures that contribute to the recalcitrant phenotype in overlap syndromes.

  • 4

    Cholangiocytes actively drive inflammation in overlap syndromes, creating a self-perpetuating inflammatory loop with the immune system.

  • 5

    Emerging biologic therapies targeting specific molecular pathways offer new hope for managing difficult-to-treat overlap syndromes.
