WNT10B and post-traumatic stress disorder: We were interested in understanding the probable involvement of miRNAs as well in the regulation of WNT10B expression in PTSD as we have previously reported significant downregulation of miRNAs in PTSD patients and showed that IFNγ, IL-12 and several other genes of the immune system, are regulated by miRNAs whose expression is decreased in PTSD (Zhou et al. 2014; Bam et al. 2016a, b, 2017).
