PACAP6-38 administration decreased the overexpression of synaptic-associated proteins and restored the aberrant synaptic ultrastructure in CM rat model. A - C . Representative bands and quantification of PSD-95, syt-1 and syp protein levels showed that these proteins were significantly increased in the NTG + vehicle group compared to the saline + vehicle group, while PACAP6-38 blocked these effects. E – G . Representative images of the synaptic ultrastructure in the four groups. H - J . The width of the synaptic cleft ( H ) was decreased, and the thickness of PSD ( I ) and the synaptic interface curvature ( J ) were significantly increased in the NTG + VEHgroup compared to the Saline + VEHgroup. In the NTG + PA6-38 group, these abnormal alterations were alleviated. Mean ± SEM. n = 3/group. One-way ANOVA with Dunnett’s post hoc test; Scale bars = 500 nm. * p < 0.05, ** p < 0.01, *** p < 0.001 compared with saline + vehicle group, & p < 0.05, && p < 0.01, &&& p < 0.001 compared with NTG + vehicle group.

Inhibiting PAC1R with PACAP6-38 restored the aberrant neuronal dendritic spines via the ERK/CREB/BDNF signaling pathway in the CM rat model. A - D . Representative images of the dendritic spines in different groups. E . Golgi-Cox staining showed that the number of dendritic spines per 20 μm was significantly higher in the NTG + VEH group compared to the Saline + VEH group, and the effect was inhibited in the NTG + PA6-38 group. (F–H). Representative bands showed that the protein levels of p-ERK( F ), p-CREB ( J ) and BDNF ( H ) were significantly elevated in the NTG + VEH group compared to the Saline + VEH group. After PACAP6-38 treatment, the expression levels of these proteins were significantly reduced. Mean ± SEM, n = 3/group.
