Main text (Immunity 59, 458–476.e1–e13; February 10, 2026) In the version of the article that was originally published, the legend colors in Figure 2K were inadvertently reversed: CD8 should appear in green and PD1 in red. This has now been corrected in the figure panel and the corresponding figure legend. In Figure 4J, the bottom left panel (Old WT IL-10) was inadvertently populated by the same image as the top right panel (Old control) during the final figure assembly.

Abstract Old age is associated with a decline in cognitive function and an increase in neurodegenerative disease risk1. Brain ageing is complex and is accompanied by many cellular changes2. Furthermore, the influence that aged cells have on neighbouring cells and how this contributes to tissue decline is unknown. More generally, the tools to systematically address this question in ageing tissues have not yet been developed.
