Proposed spatial niche framework for senescent liver-resident immune cells in chronic liver disease
This review proposes a 'spatial niche remodeling' framework linking senescence programs in liver-resident immune cells to their position along the portal-to-central axis of the liver lobule and to chronic liver disease. It is a proposal, not a validated clinical tool. [1]
Automatic summary · not editorially reviewed
The key findings
The review states that with age and chronic injury, liver-resident immune cell populations undergo senescence-associated changes spatially organized along the portal-to-central axis of the hepatic lobule. [1]
The authors propose a 'spatial niche remodeling' framework integrating cell-intrinsic senescence programs with lobular context and roles across chronic liver disease. [1]
The review discusses barriers to clinical translation and names spatial multi-omics, humanized models and epigenetic clock-guided trials as priority research areas. [1]

Liver immune cells and lobular position
The liver combines metabolism, detoxification and immune surveillance. Constant exposure to gut-derived antigens, molecular patterns and metabolites via the portal vein requires a balance between tolerance and immune activation. This balance depends on several liver-resident immune cell populations, including Kupffer cells, liver sinusoidal endothelial cells, hepatic stellate cells, dendritic cells, tissue-resident memory T cells, innate-like T cells (MAIT, NKT, γδ), innate lymphoid cells and neutrophils. With age and chronic injury, the review states these populations undergo senescence-associated changes that are spatially organized along the portal-to-central axis of the hepatic lobule.

Proposed mechanisms behind immune cell senescence
The review lists several mechanisms: telomere dysfunction and accumulated DNA damage driving persistent activation of the p53/p21 and p16/Rb pathways; mitochondrial dysfunction with leakage of mitochondrial DNA that fuels the senescence-associated secretory phenotype via the cGAS-STING pathway; epigenetic age acceleration, including genome-wide H3K27me3 heterochromatinization; and metabolic reprogramming toward glycolysis and lipid accumulation. The authors propose a 'spatial niche remodeling' framework to integrate these cell-intrinsic programs with the lobular context, rewired intercellular communication and roles across chronic liver disease, from steatosis through steatohepatitis, fibrosis and cirrhosis to hepatocellular carcinoma.

Senotherapies and open translation barriers
The review critically evaluates emerging senotherapeutic strategies aimed at specific liver-resident immune cell subsets and discusses barriers to clinical translation. It identifies priority areas for future investigation, including spatial multi-omics, humanized models and epigenetic clock-guided clinical trials. These are proposed research directions, not established treatments or validated clinical approaches.
