Infusion of soluble laminin-1 promotes neurodegeneration in tPA-deficient
mice. TPA-deficient mice were infused with mouse laminin-1, plasmin-digested
laminin-1, or buffer for 5 d, and then kainate was injected. Two days after
kainate injection, the mice were killed and brain sections were prepared. The
brain sections were processed for anti-laminin-1 immunostaining (A, D, and G)
or cresyl violet staining (B, C, E, F, H, and I). Infusion of soluble
laminin-1 or plasmin-digested laminin-1 promoted neurodegeneration in
tPA–/– mice (E, F, H, and I).
Higher magnification of the boxed areas in B, E, and H is shown in C, F, and
I, respectively. Ln, laminin immunostaining; CV, cresyl violet staining. Bar
in H for A, B, D, E, G, and H, 500 μm; bar in I for C, F, and I, 25
μm.
