Title Age-related changes in blood and spleen-derived immune cells in long and short lived mice strains [RNA-seq]
Organism Mus musculus
Experiment type Expression profiling by high throughput sequencing
Summary Immune system aging contributes significantly to declining health with age. It is unknown to what extent human and mice immune systems go through similar age-related changes and whether there are conserved biomarkers of aging. We characterized age-related changes in the immune system of long (C57BL/6J) and short-lived (NZO/HILtJ) strains and compared them with blood-driven human aging signatures. Peripheral blood lymphocytes (PBL), spleen cells and spleen-driven naive and memory CD8+ T cells were profiled using flow cytometry, RNA-seq and ATAC-seq from young (3 months) and old (18 months) mice. Pro-inflammatory myeloid genes were activated with age across strains and tissues, echoing human 'inflammaging' signatures. ATAC-seq footprinting analyses uncovered increased binding of pro-inflammatory transcription factors with age (e.g., AP1 complex, NFKB signaling pathway). Machine learning models identified inflammation, cytotoxic, and naive T cell derived genes to be strong signatures of immunosenescence. These data are publicly shared as a resource for immune aging (https://immune-aging.jax.org/mice).
 
Overall design Spleen, PBL and spleen sorted CD8+ T cell profiles of B6 and NZO mice at 3,12 and 18 months
