Hepatocyte senescence and its immune interactions in metabolic fatty liver disease: a concise mini-review exploring mechanisms and implications.
Key Takeaways
- Senescent hepatocytes accumulate in MASLD and can persist when metabolic stress continues, promoting local tissue alterations.
- Persistent SASP signaling from retained senescent hepatocytes drives inflammatory activation of macrophages and fibrogenic activation of hepatic stellate cells.
- Effective immune surveillance can clear senescent hepatocytes transiently, but impaired or overwhelmed clearance favors fibrotic progression in chronic MASLD.
