Western blot detected the downstream signaling of IFN in WT and YAP-/- astrocytes just before and after IFN therapy (2 ng/mL) at indicated time point. (B ) Quantitative analysis of the absolute p-STAT3 level (normalized to total STAT3) (B), the relative SOCS1 (C), and SOCS3 (D) (normalized to time zero point) as shown in (A) (n = 3 per group, normalized to 0 h). (E) RT-PCR evaluation showed the relative gene expression of Ccl3, Ccl4, Ccl8, Ccl9, and SOCS3 in WT and YAP-/- astrocytes prior to and right after IFN therapy (two ng/mL) for 1 h. Chosen histogram was shown at higher magnification. (F) Double immunostaining evaluation of Flag (green) and nestin (red) in YAP -/- astrocytes transfected with Flag-SOCS3. (G) Quantitative analysis of nestin intensity in YAP-/- astrocytes transfected with Flag-SOCS3 or untransfected astrocytes. (H) Immunostaining analysis of p-STAT3 (red) in YAP-/- astrocytes cotransfected with GFP/Flag-SOCS3 (1 : three) just before and soon after IFN remedy (2 ng/mL). (I) Quantitative evaluation of your intensity of nuclear p-STAT3 in YAP-/- astrocytes transfected with Flag-SOCS3 induced by IFN. (J) A working model illustrates YAP’s function in reactive astrocytes and neuroinflammation. White arrowheads indicated transfected astrocytes. Scale bars, 20 m.

Sixteen hours following injection, the dye was of course accumulatedin the brains with the mutant mice, but not in WT mice (Fig. 7A,B), demonstrating impaired BBB permeability within the mutant mice. This view was additional confirmed by intravenous injection| Cerebral Cortex, 2016, Vol. 26, No.Figure 7. Impaired BBB permeability and altered BBB structure in Yapnestin-CKO brain.

(E) Confocal images of blood vessels labeled by laminin (green) and 70 kDa dextran (red) in P20 cortex of Yapf/f and YapnestinCKO mice (sagittal sections). White arrows indicated the dextran-labeled cells, and white arrowheads indicated the leaked dextran from blood vessels. The selected regions had been shown at higher magnification. Scale bars, 20 m.
