Our results showed that the expression of BDNF was significantly higher in NAM-treated and NAM+ANA-12-treated groups at 7 d after stroke than BDNF expression level in the NAM+FK866-treated and saline-treated groups (Figures 4(a) and 4(b)), thereby showing a similar trend in NAD+ levels detected in the same groups at the same time point. Here, BDNF is linked to stroke disorder.
