Effects of Notch1 siRNA on the microglial activation, inflammatory cytokines production, BWC, modified Garcia scores, and neuronal injury after 24 h SAH. Notch1 siRNA decreased Iba1- and CD68-positive cells in the left cerebral cortex at 24 h post-SAH (a). The protein levels of the proinflammatory cytokines IL-1β (b), IL-6 (c), and TNF-α (d) were decreased while the levels of the anti-inflammatory cytokine IL-10 (e) were increased in the SAH + Notch1 siRNA group compared with the SAH + Scramble siRNA group; n = 6 in each group. Notch1 siRNA treatment significantly alleviated BWC (f) (n = 6/group) in the left hemisphere and increased modified Garcia score (g) (n = 12/group) at 24 h post-SAH, representative FJC and NeuN staining images (h), and quantitative analysis of FJC-positive cells (i) (n = 6/group) in the left cortex after SAH with Notch1 siRNA injection. Data are expressed as the mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001 versus Sham, #P < 0.05, ##P < 0.01, ###P < 0.001 versus SAH + Scramble siRNA group. Scale bar = 50 μm
