In order to investigate the effect of miR-142 inhibition on hippocampal inflammation in PTSD rats, the levels of the proinflammatory cytokines (IL-1β, TNF-α, and IL-6) and anti-inflammatory cytokine (IL-10) were measured by ELISA, western blot, or immunofluorescence. This evidence concerns the gene IL6 and post-traumatic stress disorder.
