Raises a question worth testing. It does not answer one.
This is a narrative review synthesizing current understanding of cellular senescence in liver pathophysiology, emphasizing dual protective and pathologic roles depending on disease stage and context. The authors propose that therapeutic modulation of senescence—via pro-senescence, senolytic, senomorphic, and immune strategies—may offer future benefit in chronic liver disease and hepatocellular cancer, but this remains a conceptual framework rather than evidence from clinical trials.
Journal article. Hepatic cells and tissue; review does not report clinical patient data..
Senescence acts as a stress-response program coordinating cell-autonomous growth arrest and non-cell-autonomous tissue remodeling Senescence exerts dual and often opposing effects along the liver disease trajectory, protective in early tissue repair but pathologic in chronic liver disease and tumor progression Emerging therapeutic interventions targeting senescence include pro-senescence, senolytic, senomorphic, and immune-modulating strategies
Specific cell types and disease stages in which senescence is protective versus harmful are not rigorously delineated with evidence.
This review provides a conceptual foundation for understanding senescence in liver disease but does not directly inform clinical practice. Clinicians should recognize this as a state-of-knowledge synthesis identifying senescence as a potential therapeutic target, pending rigorous preclinical and clinical validation.

Cellular senescence is a stress-response program that coordinates cell-autonomous growth arrest and non-cell autonomous remodeling of the tissue environment. Initially defined through its role in aging and tumor suppression, senescence is now recognized as a highly complex program shaped by cell-intrinsic and environmental factors. This complexity places senescence as a broad stress response mechanism operating at the intersection of metabolic dysfunction, chronic inflammation and tissue repair. Given its constant exposure to metabolic, inflammatory and toxic stress alongside its high regenerative demands, the liver is particularly prone to engage senescence as a protective mechanism to maintain tissue integrity. In this context, senescence exerts dual and often opposing effects. This review discusses the multifaceted roles of senescence along the liver disease trajectory, from its early protective functions in tissue repair to its later pathologic contributions to chronic liver disease and tumor progression, underscoring how cell type, stage of senescence program, disease stage and microenvironmental cues shape these divergent outcomes. We highlight the potential of emerging therapeutic interventions that modulate senescence, including pro-senescence, senolytic, senomorphic, and immune-modulating strategies. Advancing our understanding of the multifaceted roles of cellular senescence will be essential to translate this knowledge into therapies that selectively modulate senescent cell states, harnessing their beneficial effects while limiting their detrimental roles in chronic liver disease and cancer.
