FKBP5 and post-traumatic stress disorder: Amygdalar FKBP51 mRNA levels (n = 6–8) were significantly affected only by PTSD induction (P = 0.043); t-test comparisons, Bonferroni corrected, indicated that amygdala FKBP51 levels were only affected by PTSD induction if preceded by CRF-inducedPNS (P = 0.002, Fig. 3e).
