However, although a significant relationship between altered expression levels of exosomal miRNAs and mPFC miRNAs was suggested in our FKBP5 KO mouse model (Fig. S2), it should be noted that the candidate miRNAs showing altered expression levels observed in the human PTSD model may originate from other tissues or different brain regions. The gene discussed is FKBP5; the disease is post-traumatic stress disorder.
