Figure 6. Effects of CVS on the number of PVN CRFR1-GFP, c-Fos/CRFR1, and pCREB/CRFR1 cells.
(A) The female PVN had significantly less CRFR1-GFP than the male, regardless of treatment, with no effect of CVS on CRFR1-GFP in either sex. (B) Representative PVN CRFR1-GFP images for NS and CVS female and male mice. (C) CVS males had significantly fewer c-Fos/CRFR1 co-localized cells than non-stressed male counterparts, with no differences between female groups. (D) Representative c-Fos/CRFR1-GFP labeling in female and male mice from NS and CVS treatments. (E) Males had an overall greater amount of pCREB/CRFR1 co-labeled cells than females, regardless of treatment condition, with representative PVN pCREB/CRFR1 images from NS and CVS female and male mice shown in (F). NS, non-stressed; CVS, chronic variable stress. Data are presented as mean ± SEM, and significance threshold set to p<0.05. * Indicates statistical significance p<0.05. ** indicates p<.01.
