Article Title: Tetramethylpyrazine Produces Antidepressant-Like Effects in Mice Through Promotion of BDNF Signaling Pathway
doi: 10.1093/ijnp/pyv010
Figure Lengend Snippet: Anti-BDNF (brain-derived neurotrophic factor) infusion blocks the neurogenic effects of tetramethylpyrazine (TMP). (A) Representative confocal microscopic images show the staining of doublecortin (DCX; green) in the dentate granule cell layer. The scale bar is 200 µm for representative images and 50 µm for enlarged images, respectively. Density statistics showed that the increased number of DCX positive cells induced by TMP was blocked by anti-BDNF infusion. (B) Representative microscopic images showed the co-staining (yellow) of Neuronal Nuclei (NeuN) (green) and 5-Bromo-2-deoxyUridine (Brdu) (red) in the dentate gyrus (DG). The scale bar is 100 µm. Density statistics showed that co-injection with the anti-BDNF antibody blocked the TMP effects on the amount of NeuN+/Brdu+ cells in the DG. Data are expressed as means ± standard error of the mean (n = 5); * p < 0.01; n.s., no significance. Comparison was made by one-way analysis of variance followed by a post hoc LSD test.
