Presence of IL-1β receptor-expressing cells in the choroid plexus stroma. Immunohistofluorescence staining revealed that some choroid plexus stromal cells expressed IL-1 receptor type I (IL-1R1) (A, arrows) and IL-1 receptor accessory protein (IL-1RAcP or IL-1R3) (B and C, arrows). The morphology and distribution of IL-1R1-immunopositive cells and IL-1RAcP-immunopositive cells were similar. The photomicrographic images were taken using sections from mice fixed 4 h after LPS injection. Nuclei were counterstained with DAPI. Bars =20 μm.
