Fig 5. Effects of KL on the NO release and expression of target proteins measured by western blotting and immunofluorescence analysis.
(A) Immunoblots of brain hippocampus homogenates with antibodies specific for 5-HT1AR, p-CREB, CREB, p-PKA, PKA, and nNOS. (B) Effects of KL on the release of NO in the hippocampus. *, **: different from the NO content of the blank group, P < 0.05, P < 0.001; ##: different from the NO content of the control group, P < 0.001; n = 12, mean ± SD; Bla: blank group, Con: control group, Bus: buspirone group, KL: Kadsura longipedunculata group. (C) Confocal immunofluorescence analysis of rat hippocampus with 5-HT1AR mAb (red) and neuro trace (green). The neuro trace was used to identify neurons.
