Fig. 6: Capsaicin administration did not change TRPV1 expression.

A, B The protein expression of TRPV1 was measured by Western blot in the prefrontal cortex and hippocampus (n = 3 per group). C, L Representative immunofluorescence images show the expression of TRPV1 (red pixels), NeuN (green pixels), and DAPI (blue pixels) in the frontal association cortex (FrA) and in the hippocampal CA1, CA3, and dentate gyrus (DG) regions (n = 3 per group). D–K Quantitative analyses of the percentage of NeuN and TRPV1 co-labeling. Quantitative analysis of results and data are represented as mean ± SEM, n = 3 for each group; *P < 0.05; **P < 0.01.
