Extended Data Fig. 5: The human choroid plexus harbors CD8+ and CD4+ T cells.

Lateral ventricle-derived choroid plexus was procured from three healthy human donors and stained for CD8α, CD4, or isotype control (cyan) and DAPI (magenta). Experiments show one representative image from n = 2 replicate sections from each human donor. Scale bar = 20 μm. Graphical illustrations were created using BioRender (https://biorender.com).
