Figure 9

In cell-type-specific analyses in the STR, the levels of Lamin B1 and HMGB1 are significantly lower in both astrocytes and microglia in α-syn PFF-injected mouse brains than PBS-treated ones, whereas the levels of p21 in both cell-types are increased with α-syn PFF. In the STR, both GFAP (A–C) and Iba-1 (E–G) were increased in PFF-injected STR (n = 6/group). The intensities of Lamin B1 and HMGB1 in both astrocytes (A,B,D) and microglia (E,F,H) were reduced, while the levels of p21 were significantly higher with α-syn PFF (C,D,G,H). The label intensities of Lamin B1, HMGB1 and p21 were quantified cell-type specifically (GFAP or Iba-1), based on double-labels in a blinded manner. DAPI stain (blue) was used to indicate the location of nucleus. In quantification, PBS injected STR region was used as a relative label intensity (100%, n = 5–6/group) in mean ± SEM and applied to unpaired Student’s t-test for statistical significance. ****: p < 0.0001.
