In vivo antidepressive effects of nanocapsules. A In vivo Cy7.5 fluorescence of C57BL/6J mice and CUMS mice after intravenous injection with VCNCs-Cy7.5, CNCs-Cy7.5, and VNCs-Cy7.5 at 400 μg 5-HT/kg for 3 h and 7 h. Living Cy 5.5 fluorescence images of mice after treatment with VCNCs-Cy5.5, CNCs-Cy5.5, and VNCs -Cy5.5 (C5-HT: 400 μg /kg) for 3 h. The representative western blot analysis of B Nrf 2 in the hippocampus of brain across all groups. The other two replicates were presented in Additional file 1: Fig. S38. Reverse transcription quantitative polymerase chain reaction analysis (RT-qPCR) of relative mRNA levels of C NLRP3 in the hippocampi of mice in all groups (n = 3). The levels of hippocampal D IL-6 in the mice hippocampi after treatment were detected using ELISA kits. The results were normalized by the protein concentration of each sample (n = 3). E ROS/DAPI staining and F GFAP / DAPI staining brains in groups subjected to different treatments. Analysis of hippocampal BDNF expression using G western blot, H RT-qPCR, I ELISA kits and J immunohistochemistry slides. The significant differences between groups were analyzed using the one-way ANOVA method, *P < 0.05, **P < 0.01, *** P < 0.001
