IL6 and post-traumatic stress disorder: Additionally, the Western blot assay techniques revealed that PTSD led to an elevation in IL-6 levels, a pro-inflammatory cytokine, and a reduction in IL-10 levels, along with a decrease in glucocorticoid receptor expression in both brain regions, which was also counteracted by a subthreshold amount of tBHQ.<h4>Conclusion</h4>These findings suggested that the beneficial effect of tBHQ on anxiety and depression induced by PTSD through hippocampal and amygdala MAO-A, MAO-B, IL-6, and IL-10, and glucocorticoid receptor.
