Lymphoid neogenesis and immune infiltration in aged liver.

Unlabelled: Immune dysregulation and inflammation play a major role in the pathology of age-related disorders. In an earlier study, the microarray data from our laboratory indicated an increase in inflammation-related gene expression in the liver with age. We further investigated immune-related changes in the aged liver and found that the levels of inflammatory cytokines, chemokines, and inflammatory genes were higher in aged animals.
