Extended Data Fig. 7: Neurogenic niches in microbe-experienced mice have increased presence of T cells.

(a) Representative immunofluorescent images of CD8α+ T cells (green) and CD31+ vasculature (magenta) across neurogenic niches (subventricular zone and dentate gyrus) of n = 3 mice per group after D60 + . (b) Same as A but for CD4+ T cells (green). Experiments in (a,b) show one representative image from n = 3-4 replicate mice at every neurogenic niche region from 2 independent experiments. Scale bar = 200 μm. Graphical illustrations were created using BioRender (https://biorender.com).
